v.iii-liter Chevy Engine Issues: What Should You lot Expect Out For?
Chevy's 5.3-liter V8 is known for its long-term lifespan and trustworthiness, but no engine is without problems. What should you look out for?
Ask any possessor of a Chevy 5.3-liter V8-powered vehicle about its dependability, and they'll likely tell you virtually how they've never had any major issues with it. The stigma that a Chevy V8 is reliable is rooted in decades worth of history and development. Over the years, technology'southward progression has led united states to V8 engines that are trustworthy, reasonable in terms of fuel economy, and put out enough power to go wherever gamble may take u.s.a.. In fact, it is not a rare occurrence for a 5.three Chevy to go above and beyond 200,000 miles. All the same, no engine or car is entirely without flaws. If you are in the marketplace for a Chevy five.3 vehicle, there are some things to look out for.
Earlier nosotros swoop into the issues, let's take a glance at the history of the Chevy 5.three and what vehicles you might detect them in.
The 5.3-liter displacement has remained the aforementioned for over 20 years now. It was start introduced in 1999 as a truck variant of the LS engine found in Chevrolet Corvettes and Camaros. Though many of the parts from an LS fit and the 5.3 are based on the same platform, the initial v.3-liter V8 had a cast-iron engine cake rather than aluminum similar you'd observe in the sports car going LS engine. Since then, the 5.3 has gone through 3 generational changes with a slew of variations between those changes.
Chevy 5.3 Generations and Changes
The initial run of the Chevy 5.iii-liter V8 comes in the third generation of Chevy'southward pocket-size-block V8 engine. For marketing purposes, this engine is known as the Vortec 5300. As nosotros mentioned before, it first became available in 1999. You'll find this engine in the Chevy Silverado and Avalanche too as the GMC Sierra. Additionally, this engine is under the hood of SUVs similar the Chevy Suburban and Tahoe, Cadillac Escalade, and the GMC Yukon. It is also plant in work vans like the Chevy Limited and GMC Savana. The Generation Three Smallblock V8 ran until 2007.
In 2005, Chevrolet released the quaternary generation smallblock V8. The name Vortec 5300 remains the same for this generation. While power did increase, this generation's biggest advancements are cylinder deactivation applied science known every bit Agile Fuel Management. When driving in atmospheric condition that do not require full engine power, the engine volition shut off four cylinders to salve fuel. This allows gen-four v.three equipped trucks to surpass 20 MPG highway. Similar the gen-three engines, you'll detect these 5.iii V8s in just about every GM truck, SUV, and van. The gen-four 5.3 is still produced for utilise in piece of work vans.
Finally, the fifth-generation smallblock brought a proper noun change for the v.three to the Ectotec3 5.3. This is the engine you'll find in GM trucks and SUVs from the model twelvemonth 2013 and newer. These engines feature both variable valve timing and cylinder deactivation with the addition of straight injection. Furthermore, all Ecotec3 engines are flex-fuel compatible, pregnant yous can run them on E85 without whatsoever altercations. Additionally, a hybrid version of the Ecotec3 5.3 is available, increasing the city fuel economy into the 20 MPG range.
Generation-three Vortec 5300 Problems
While the gen-three Vortec 5300 is the to the lowest degree complicated in terms of technology, information technology still has a few problems to scout out for when shopping. If y'all are in the market for a Chevy or GMC truck or SUV from 1999 to 2007, you may be looking at vehicles equipped with this engine. The easiest way to tell if a vehicle you lot're looking at is a gen-three or gen-four Vortec 5300 is to see if it has Active Fuel Management or cylinder deactivation. If information technology does not, it is a gen-three engine. Equally always, before purchasing any vehicle, use our free VIN enquiry tool to get a report on the vehicle's life, maintenance, and accident history.
A prominent issue you may see with the gen-three Vortec 5300 is gradual coolant loss due to a croaky cylinder head. While this outcome was not common enough to warrant a call up, GM did issue a technical service bulletin (TSB) about the problem. The issue stems from a manufacturing flaw when the cylinder heads were produced past an outsourced visitor called Castech.
Not all Castech heads have the outcome, and not all Vortec 5300 engines have Castech heads, so determining if a vehicle has or may accept this upshot can be a scrap difficult. The most straightforward way to see if the vehicle currently has this issue is to see if the vehicle is experiencing any engine coolant loss over fourth dimension. If non, the vehicle likely does non take the issue. Notwithstanding, if it does accept Castech heads, it may eventually encounter this issue. A pre-purchase inspection mechanic can remove the valve covers from the cylinder head and see if the head has the Castech marking stamped into them. If they do, you may somewhen run into the consequence.
Generation-three Vortec 5300: Additional Issues
Another issue yous may encounter with gen-iii Vortec 5300 engines is the failure of intake manifolds and intake manifold gaskets. Again, in that location is no official call back for this issue. Even so, gaskets are wear items that eventually tend to fail, and many higher mileage 5.three engines run into this issue. Furthermore, the intake manifolds are made of plastic and may be prone to cracking over time.
Symptoms of faulty intake manifolds or failed gaskets may include rough idling or stuttering and noticeable power loss when driving. In some cases, if the result is prominent enough, it may crusade a check engine light for misfires. This, again, is something a pre-buy inspection could identify.
Another issue gen-three Vortec 5300 engines commonly experience is the failure of the fuel pressure regulator. This may cause the vehicle to exist hard to start or may even prevent it from starting entirely. Additionally, it can crusade rough idling and stuttering, poor acceleration, and prematurely fouled spark plugs. Luckily, the fuel pressure regulator is easily accessed and inexpensive. This is a quick and elementary chore for an experienced mechanic. So, if a vehicle y'all're looking at has this issue and you can spare a day for information technology to be repaired, it may be a skilful mode to pick up a truck or SUV cheap.
Every bit with whatever car of this historic period, other engine-related gaskets may exist failing, spark plugs could need replacing, or in that location could exist a buildup of engine sludge if they are not well maintained. No affair how reliable an engine is, neglect can prematurely finish its service life. It'due south imperative to know a vehicle'due south service and repair history before purchasing.
Generation-four Vortec 5300 Bug
With advocacy also comes more than complex issues. While the fourth-generation Vortec 5300's Agile Fuel Management cylinder deactivation arrangement was a major leap forwards in the efficiency of V8 engines for GM, it was also ultimately one of the downfalls of this engine.
While this is yet another issue that is non nether retrieve, there is currently an active class-activeness lawsuit regarding 2010 through 2014 Vortec 5300 engines. The lawsuit alleges that owners experience excessive oil consumption due to a combination of the Active Fuel Management organisation and faulty PCV valves, which can describe oil out of the valvetrain and into the intake before it is burned in the combustion chambers. This lawsuit also claims the piston rings fail to maintain force per unit area in the crankcase and that a faulty oil force per unit area relief valve sprays oil directly at the piston skirts, overloading the rings and allowing oil to sneak past into the combustion bedroom. Many owners are using a quart of oil every 1,500 to 2,000 miles.
Furthermore, some owners say that their oil life monitoring system does not notify them when the engine is low on oil as information technology should. The combination of these issues can lead to unknowingly running the engine low on oil. Running an engine depression on oil tin crusade expensive damage like bearing failures, piston band failure, bent rods, and more. Many of these issues tin consequence in a necessary rebuild or entire replacement of the engine.
Overall, when shopping for a GM truck or SUV, it is best to tread lightly for these models and model years:
- 2010-2014: Chevrolet Silverado
- 2010-2014: Chevrolet Suburban
- 2010-2014: Chevrolet Tahoe
- 2010-2014: Chevrolet Avalanche
- 2010-2014: GMC Sierra
- 2010-2014: GMC Yukon
- 2010-2014: GMC Yukon XL
Generation-four Vortec 5300: Additional Problems
Some other upshot stemming from the same roots as the oil consumption problem is the gen-four Vortec 5300'south tendency to prematurely foul spark plugs. This, again, is an issue that is not under call up. Still, GM best-selling this trouble and released a technical service message outlining steps necessary to repair and prevent this issue, similar the gen-three cylinder head bug. The TSB outlines the fact that the valve encompass design on engines built before Feb 1st, 2011, has a poorly designed PCV pullover that volition draw oil out of the valve train and into the intake manifold and combustion chambers, exactly as the oil consumption lawsuit alleges.
Furthermore, the same TSB outlines problems with piston rings incorrectly sealing and allowing oil into the combustion chamber thanks to faults in the Active Fuel Direction system, as the lawsuit likewise alleges. According to the TSB, these faults are found on engines built before October 1st, 2010. The vehicles specifically listed in the TSB are below:
- 2007-2011: Cadillac Escalade Models
- 2007-2011: Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe
- 2010-2011: Chevrolet Camaro
- 2007-2011: GMC Sierra 1500, Sierra Denali, Yukon Models
- 2008-2009: Pontiac G8 GT
Gen-four Vortec 5300s also confront similar issues with intake manifold failures that the gen-three engines experience, as they as well are equipped with plastic intake manifolds.
In full general, it is appropriate to tread lightly when shopping in the range of 2007 to 2014 Vortec 5300 equipped vehicles. The Agile Fuel Management system tin be disabled. However, faulty PCV systems and fouling spark plugs are still an upshot. If you lot are looking to purchase in this appointment range, be certain to enquire for repair history to come across if the TSB repairs accept been washed to forestall yourself from getting in hot water.
Generation-five Ecotec3 v.three Problems
The Vortec 5300 namesake was finally replaced with the fifth-gen smallblock family, starting with model yr 2014 trucks and SUVs. The 5.three engine is at present known as the Ectotec3 five.3-liter V8. The major difference betwixt these engines and the Vortec 5300 engines is the fuel injection system. While Vortec engines use port injection at the intake manifold, Ecotec3 engines are direct injected. This means the fuel is sprayed straight into the cylinder rather than into the intake manifold. Most new vehicles use direct injection as information technology is a more than efficient and precise mode to command fuel that allows better fuel economy. However, direct injection does take ane major flaw, and the Ecotec3 engines are not exempt.
Straight-injected engines tend to encounter carbon buildup on valves and the within of the intake manifold. This is because there is no high-pressure fuel being sprayed on them to keep them make clean, as you'd see in a port injection engine. While there are cleaners that owners or mechanics can spray into the intake available to forestall excessive buildup, they will not foreclose buildup entirely. Many direct-injected engines need their valves and intakes cleaned via walnut blasting. This is a process that blasts the components with finely footing walnut shells via a loftier-force per unit area air organization. Walnuts are used considering they are biodegradable and are soft enough not to harm engine components while cleaning them. While this event isn't exclusive to the Ecotec3 five.3, it is worth keeping in heed.
Excessive carbon buildup in the intake system can cause rough idling, stuttering, misfires, and decreased power. These symptoms may go more noticeable over time as college mileage engines accumulate more carbon buildup.
Generation-five Ecotec3 5.3: Additional Problems
Another issue Ecotec3 engine owners may run into is failing fuel injectors. Given the nature of direct injection wherein fuel injectors are spraying direct into the combustion chamber, these injectors are exposed to a lot of heat and pressure. Eventually, they may wind up failing. This can result in either a instance of too much or not enough fuel, as injectors tend to fail open up or airtight. In either example, your engine will run incorrectly and may cause misfires and check engine lights. Though injector failure is not a premature upshot, information technology is certainly something to watch out for when looking at college mileage Etoctec3 equipped vehicles.
Equally of at present, this seems to exist the only concern of the Ecotec3 v.3 engine. While it does still use the GM Active Fuel Direction cylinder deactivation technology that caused a plethora of issues on the gen-four Vortec 5300 engines, it seems that GM has solved the issues related to excessive oil consumption.
Chevrolet five.3 Engine Problems and Recommendations
If you're shopping for an older used 5.three equipped Chevy, your best solution to avoid any major problems is to detect a low mileage and well-maintained gen-iii Vortec 5300 vehicle. Given that the major issues with oil consumption started in 2007, a 2006 or older model is a safe bet.
If you lot are searching for something newer with a 5.iii, then it is best to expect to models from 2014 or newer that are equipped with the Ecotec3 5.iii. They offer the later Vortec 5300 engine benefits like variable valve timing and cylinder deactivation for increased fuel economy without excessive oil consumption or spark plug fouling PCV issues. Practise keep in listen that yous may eventually have to pay for intake cleaning due to the direct injection system, though.
As with ownership any used car, nosotros tin can't recommend properly researching the vehicle'south VIN and service history prior to purchasing. Don't be afraid to inquire questions near what has and hasn't been done. Furthermore, many mechanics offer a pre-purchase inspection that can prevent you from ownership a motorcar with issues that aren't immediately obvious. This tin air current upwards saving you thousands in the long run.
Overall, a Chevy 5.3 equipped vehicle will go the job done, whether it be driving to the grocery shop or pulling a camper trailer for a weekend getaway. Knowing what to look for before buying is half the battle and ultimately will country you lot in your perfect vehicle.
Ofttimes Asked Questions
Aug 30, 2021
How long volition a five.three Chevy engine concluding?
A Chevrolet v.3L engine should be able to concluding 200,000 to 300,000 miles depending on how you care for the engine. These engines were first introduced in 1999 and they were used through the 2009 model year. They have been referred to every bit the Vortec 5300 when they were used in trucks.
The Chevy 5.3L engine is known to be very reliable because it was not pushed hard by Chevrolet, and they are congenital very strongly. The main block of the engine is virtually indestructible, you would have to send a piston through the side of it to interruption the block. This is a key to making an extremely reliable engine.
When you have a Chevrolet 5.3L engine you will need to do the normal services and replace some gaskets as they vesture out, but there are very few reports of the engine failing and leaving drivers stranded on the side of the road.
How much HP can a 5.3 Vortec handle?
During the 20 year production run for the Chevrolet 5.3L engine, it produced 270 horsepower to 295 horsepower direct from the factory depending on the vehicle that it was in. Since there are and then many 5.3L engines out on the market an aftermarket customs has formed around the engine and they are now very modifiable.
The stock internal components for the engine are by and large considered to be adept to virtually 450 horsepower. Whatever more than that and you volition want to first getting more reinforced internal parts. If you decide to upgrade the components in the engine and so y'all tin become close to 600 horsepower from the five.3L engine.
Modifying and increasing the power of whatsoever engine does event in them condign less reliable over fourth dimension. The extra stress on the components can crusade them to fail earlier, and then it is always a good idea to weigh the pros and cons before you commencement modifying any engine.
What problems do Chevy 5.3L engines take?
The most commonly reported problem for the Chevrolet 5.3L V8 engine is that in that location is excessive oil consumption from them. This is caused by the Chevrolet Agile Fuel Direction system that can crusade the vehicle to utilise 1 quart of oil for every 1,500 miles it drives. There is a known oil monitoring system problem besides so it is a good idea to physically check your oil regularly if yous have a v.3L engine.
Some other problem that happens with the Chevrolet 5.3L V8 is the cylinder heads have been known to crack. This is non a common trouble, but repairing information technology is costly. The heads that were made by Castech are the ones that are known to fail, merely in that location are 3rd-party options on the market to replace them that last much longer.
The last trouble is that the spark plugs have been known to fail prematurely due to excessive carbon buildup. This is pretty common on the 2007 and newer engines because of the revision to the valve cover design. Overall the Chevrolet 5.3L engine is very reliable, but there are a few problems that pop up.

I must of picked a good year LOL! 2016 Chevrolet Silverado Truthful North edition (Reside on Vancouver Island, British Columbia, Canada) LT w/tow bundle - 5.3L83, 6sp. 6L80E trans, iv × 4. Bought the truck brand new off the lot, had a few minor warranty issues every bit it saturday in the rain as a demo model (ODO -164 km). Brand new warranty OEM starter motor, make new warranty OEM exhaust (waste - gate/flap consequence), and the GM dealerships have been 100% - excellent in my experience. Had to accept a new OEM warranty injector installed also; got done at the same time as exhaust. ***MUST HAVES*** RANGE AFM DIABLER - OIL CATCH Can MOBIL 1 EXTENDED Performance OIL Apply FUEL System CLEANER W/PEA KEEP INTAKE & VALVES Clean My truck has seventy,000 km/45,000 miles on it and it runs smoother and improve than new. My v.3 RIPS and runs STRONG. The manual is clunky once in a while but I plan to pan drop & affluent with Amsoil full syn. ATF. Smoooooth on the highway, drives similar new. The locking back axle makes it certain - footed in the wet slop; I can drive upwardly mountains and play in the snow drifts - Falken Wildpeak A/T3W'S = excellent A/T treads. The ONLY part I've ever had to pay coin for in order to replace it was for a burned out tail light bulb 7444. LOL. I bought the truck in Dec. 2016 and have i year and 9 months left on the 7 year extended warranty. Love this truck. v/5 stars

2021 sierra lifter failure
Same every bit all the rest 8600 piece of cake miles, starts misfiring on the highway, no codes at all, dealer says keep driving bring it in tomorrow, likely a transmission air problem. xx miles after nuance board is a Christmas tree, also says the park brake is locked? Pulled into the dealer, barely withal running. GM has no lifter parts and is now shut downwardly. Mine has over 8k miles so I get the shaft, GM will merely do partial repair at best. Current new 2021 delivered trks practise not have AFM, cost to change out my trk for a non AFM is 13k. Does this ready the trouble, who knows. Question is, is GM going to step upward and resolve this upshot, or are we all going to swallow this for years to come up, I presume AFM engine equipped trks will have very depression value very rapidly without GM action. Already accept 50k into it.

5.3 engine failure
2015 Silverado 100,000 miles. The engine started ticking like it had a miss. I had it towed in to my mechanic and $ 1,800 after I was back on the road but they never found the root cause of the problem. two months later on same matter ticking in the engine number seven cylinder dead aptitude push rod. I had information technology towed to a Chevy dealership they've had it 3 months and finally called yesterday $7,000 for a new engine. Told me it was starved for oil I asked why they didn't know. Merely after watching a you tube video I found the reply it's a bad valve cover not letting it get oil. I'm currently looking for a good attorney to sue GM because they've known near this defect but have washed nothing nearly it.

Disappointed Silverado Owner
Today while driving home from work in traffic, doing less than 40 miles per hour and slowing down due to a red traffic light, I heard a"pop!" coming from under the hood. I kept slow down and when I came to a complete end, the truck started shaking and I could hear a loud ticking/popping racket. I managed to drive home doing less than xxx mph. I tried to look effectually the engine bay and listen to the audio, it is definitely coming from inside the engine. I turned off the truck, turned it back on and it got worse, I barely turned on. The noise is louder at present. At present I am online doing my research and see that I am not the only owner with the exact aforementioned issue. The engines definitely failed
Brad on January ten, 2022
I'm not that lucky
First I'd like to bespeak out almost of the negative reviews are not even for this engine. This engines use was stopped in 2009. The vehicles 2010+ are not using the engine they are taking virtually. At present that that'southward out of the style. I have a 2007 Chevy Tahoe LTZ over 400K miles on hee.purchased summer of 2018 with 151K and the residual take been mine. Halloween night 2020 I had a lifted plummet and replaced around 350K . This truck still runs amazingly. I average 3-5K a calendar month . Yes there is oil consumption but if there wasn't I'd be more concerned. If information technology wasn't for the AFM causing lifted plummet I'd requite this a 5 star.

half-dozen.2 in a 2015 High Country Silverado
77,000 miles engine starts to shake and barely runs. I limp it into the Chevy dealer in Athens Georgia. Information technology sits at that place for three days and they never become a risk to await at it. They tell me they doubtable it's a aptitude push rod. $6200 repair job. I have my mechanic come up and get the truck. He says bent push rod or rods for sure, they just fixed the bosses that did the same matter. $6200 repair ticket and sold me a plug in module to deactivate the AFM. I'g done with GM, they know at that place is a problem and even have a service bulletin out for it 15-06-01-002H dated March 2019.

Bought a 2021 Silverado RST 1500 on 19Mar21.i work on the road alot and so I already accept 12000 miles on the truck in June. This morning I bulldoze the truck 5 miles and notice a ticking noise from the engine.sure sounds like either a lifter or a valve failure to me.now I accept to tow this new truck to a dealer and have it fixed.i seriously doubt that I will purchase another Chevy someday before long. Did I mention I traded a 2017 silverado with a bad transmission in for this new truck? SMH.come on GM you can do much better than this

I purchased a 2021 Tahoe with a 5.3L engine back in November 2020. I at present have fourteen,300 miles on it. Last weekend I started to feel the same issues equally anybody else on this review. Dealer told me that the lifters have failed. Parts are on back society . Non sure if at that place is whatever other serious problems until the tech gets in to the engine. My bet is there are other serious bug. I hope we all become through this nightmare. Oh and my dealer has no loaner cars available for me to use in the meantime

Unhappy chey owner
Have a 2021 Chevy 1500 Silverado Z71. Texas Edition. It has 5.3L engine. At 11000 miles the engine started knocking. Parking interruption locked up. How vehicle towed to dealer. They said a lifter had failed when asked if this was a common occurrence I was assured it was non. This week I establish out two friends have new trucks with the 5.3L engine. Both take lifter problems one at 6000 miles and 1 at 11000 miles. Anyone else experiencing this issue with the 5.3?

I wonder how much they paid this clown to write this article. Easy to encounter why he doesn't dare prove his confront in the blurry moving picture. 70k and puff! Blown lifter. Thankfully my dealer has been neat with a loaner and GM is taking the sting out. Horrible though, peculiarly for those of us that actually use our truck to work for a living only horrible for everyone really. Wouldn't wish information technology on my worst enemy nevermind a long fourth dimension customer. Best of luck to everyone

I bought my truck in November of2020 it'due south a 2021 chev z71 . My problems are just like the others, my truck had 6700 miles on it, I was going to my Dr appointment it made a popping audio and started missing. Took to dealership and was told he had 7 on the lot right at present with aforementioned problems. They didn't accept a truck to loan to me and didn't know how long it will take to get parts in and fixed!!! Employ causing when perching a 2021 with the 5.3 engine.

09 Silverado 5.3
'09 286,000 miles. Awesome engine. Effectually 200k experienced low oil pressure. Found out it was due to the smaller OEM oil filter. Was told in that location is a service bulletin recommending a unlike oil filter on loftier mileage engines. As I understand there is a bypass pressure difference. I am now running nearly 20psi vs around 40 with that filter wondering what changed? Going to try an early oil filter swap to diagnose.

Exiting an off ramp and slowing for a stop low-cal. Engine begins to vibrate and knock. Engine struggled to idle. Nuance lath lights upwardly like a Christmas Tree. Multiple System failure warnings, engine light flashing, traction control flashing. Limped information technology to the dealership. Bent lifter for sure and peradventure other issues. Waiting on parts from GM. Definitely a major issue with this engine...only 8K miles. :(

Junk for years
It'southward not just the new trucks boys. My 2013 just collapsed a lifter at 79,000. Shes been run hard merely never abused just kept up on meticulously. AFM lifter on cyl.#7. Only sold my 96 5.7L for 100$ because of the intake manifold gasket problem. All of these issues are known past GM but left for u.s. to deal with. F#@ CK You GM!!! I HAVE Ane Word FOR ANY I LOOKING AT Any GM VEHICLE........HEMI

2021 GMC bad lifters at 6600 miles
I was on a return trip from Chicago to Alabama and my new GMC started a knocking and missing noise. Dealer determined that the lifters had collapsed. I had to go out the truck 600 miles from home. I am all the same waiting for GM to advise me about my options. I have been a loyal GM possessor and have purchased four new GM trucks. I am very disappointed with GM's client service.
Ralph p on December 20, 2021
Failed lifters
2021 silverado trail boss bought new 6300 miles just like others on this page driving and the five.3 Fifty engine with 6300 miles started misfiring and the dashboard lit upwardly with several lights made it to the dealer on a wing and a prayer they say bad lifters and so far unknown on parts back ordered til who knows when other than this the truck was a bang-up

2017 5.three engine failure
Same as many here, my 2017 had engine ticking noise at 17,000 miles. Engine light came on called dealer who said bring it in correct abroad. Lifter failure, barely fabricated it to shop. Over a month later even so waiting for replacement parts and only fixing on side. VERY disappointed in GM , no more than for me. Will endeavor trading for a Titan or Tundra
thomas bengtson on February 4, 2022
Very disappointed
I own a 2013 Silverado with simply 68000 have put so much money into this truck. And now low oil pressure dealer says needs an oil pump , in all my years I never seen an oil pump just get . Life long gm possessor was expecting to put 200000 miles on this beingness my concluding truck. So much for that I retire and have get a new truck this sucks!!

2020 TrailBoss LT lifters
Reading these reviews is shocking. I made information technology to 45000 before the lifters collapsed. Information technology's been over a month with my truck at the dealer. I have a rental but dealer only covers the basic. I need to pay out of pocket for protection insurance. Super disappointed. I left Tundra trucks for this fiasco. Regret it Big-TIME!!

Bad engine
Lifter issue with parking break engaging at 16,600 miles, Chevrolet knows about the problem just knowingly keeps selling the production hoping It makes it out of warranty. This is shameful and illegal.

Everyone but the author knows about the AFM lifter failures. Mechanics know all about them. I had never heard of a lifter failure until I had one and learned virtually the AFM.
