The Engines in Chevy Silverados Were ‘Engineered to Fail,’ Class Action Lawsuit Claims

General Motors has had its share of lawsuits over the years, and the latest involves some of its best-selling trucks and SUVs. In fact, the newest lawsuit against GM alleges the engines in vehicles such as the Chevy Silverado were “engineered to fail” from the beginning, that the automaker knew about it, and that it refuses to acknowledge or fix the issue.

With so many owners complaining about the same faulty engine, it appears GM’s time to ignore its mistake has run out.

GM faces another lawsuit over fuel consumption

GM is facing a new proposed class-action lawsuit over the engines in some of its most popular models. This complaint contends some Vortec motors used in GM SUVs and trucks, such as the Chevy Silverado, are plagued with oil consumption problems owing to the defective engine. Owners contend that the fourth-generation Vortec engine was designed with flawed piston rings, leading to issues with oil consumption and even the potential for engine fire, according to CarComplaints.com.

The engine in question is the 5.3-liter Vortec in the following GM models:

  • 2010-2014 Chevrolet Avalanche
  • 2010-2013 Chevrolet Silverado
  • 2010-2014 Chevrolet Suburban
  • 2010-2014 Chevrolet Tahoe
  • 2010-2013 GMC Sierra
  • 2010-2014 GMC Yukon and Yukon XL

GM’s faulty engine and what you need to know about the lawsuit

According to the proposed class-action complaint, GM intentionally created a defective engine that was “built to fail” from the beginning. The Vortec 5300 was designed with defective piston rings, which fail to maintain oil in the crankcase and ultimately compel the engine to consume excessive oil.

The plaintiffs also claim the engine’s fuel-management system contributes to the problem. Owners say it inhibits the oil pressure gauge, so oil levels fall low. Additionally, drivers are not informed of the low levels. Some also report the problem with oil levels destroying the spark plugs, causing their vehicles to operate badly, misfire, and even stop down.

What’s more, the plaintiffs and experts believe GM has known about the oil consumption concerns since its 2007 model-year vehicles were initially offered. The lawsuit alleges the Vortec engine’s engineering problems consume too much oil, causing low oil levels, inadequate lubrication, and, ultimately, internal damage that results in huge repair costs. When confronted with concerns, GM has declined to take accountability for these repairs.

Filed with the U.S. General Motors LLC is being sued by Airko, Inc., et al., in the Northern District of Ohio’s Cleveland Division. The lawsuit alleges that GM violated both its implied warranty and Ohio’s Consumer Sales Practices Act.

  1. Bought a 2015 new out the dealership and I had to replace the transmission and air condenser all because Chevrolet put in a thermometer in the transmission so it gets stuck after a few months

  2. 2007 Suburban with 5.3l. It’s true AND the active fuel management band aid fix they threw on it to help gas mileage does exactly what this article claims. I replace the 4 plugs that “shut off” once a year. This doesn’t even scratch all the awful electrical and ground issues these vehicles have that send them into limp mode. I’m surprised this lawsuit hasn’t come long before now.

  3. This should be limited to just those years and models. Any trunk with the AFM. Something 2006 and 2007 and up all have this issue. The compress lifters causing the cylinder to misfire. You cant tell oil is low unless you constantly check it yourself and when it gets low it messes with the afm resulting in engine failure

  4. I own a 2009 Silverado. It has been an awesome truck. It did start burning oil for last 6 years. Now I have a misfire on piston 7. Dealer says bad lifter and camshaft. Suggest to replace engine. 9500.00
    172,000 miles on it.

    • Check your rear main seal. That might he where the oil is going. Next oil change sub a quart of transmission fluid for a quart of oil. Might clean up the lifter. Don’t replace the engine until it dies. Some shops are known for selling customers an unnecessary engine and then turning around and selling the old on after a minor repair or just as a junkyard motor. $10000 should by quite a custom performance engine.

  5. I have a 2012 silverado 1500 when I bought it had 72k on it the motor took a crap at 86k had to buy another motor was not happy that I’m paying the truck off and had to buy another motor. I had the same problem bad oil consumption misfiring on all cylinders smoking like a diesel running really rough… using alot of fuel . All this messed up my truck I spent alot of money fixing it

  6. If the lawsuit is worded as this article is written, GM will prevail. The problem isn’t piston rings. It is the valve stem to valve hide clearance that is causing the excess oil clearance. The production tolerances are too wide, and when the right tolerances stack up, you get oil consumption. Further, there is nothing GM did that prevents owners from checking their oil level, or following recommended maintenance schedules. Few people do either. Run the engine low on oil, bad things happen.

    GM has had numerous bulletins and campaigns over the years about this exact matter. And it isn’t just the 5.3, several Gen III/IV engines are affected. I have worked in the engine industry a long time. The industry has been very familiar with this situation for many years. This would be less of an issue if people checked oil levels, maintained their cars, and understood what was really happening. Could GM have done a few things better? Absolutely. Are these engines within industry standard? Yes, they are.

    • The motor is the problem. I do my own maintenance and check oil every 500 miles or less if not driven often. The engine consumes the oil. I don’t. Even with diligent maintenance the engine continues to consume quarts of excess oil. Problem is the engine, not all owners. Yes some could check oil more often but the engine is junk. My Ram will only consume a pint per 3000 miles at 137,000 miles.The engine is junk and nobody should ever buy any junk GM product again unless they stand behind their products. 56,000 miles on my GMC and the engine and truck value are worthless. God Made Crap in the GMC products!

    • Please clarify for me. Are you saying these problems come up only when components with tolerances on the max and min happen to come together in a given motor? Thank you.

  7. My 2013 Silverado “Black Widow Edition” that I purchased NEW and had a sticker price of $70k with the 5.3 liter Vortec engine and started using excessive oil back with 65k miles and now with 87k miles it’s getting worse. The dealership where I purchased it at is telling me that they have NO solutions to this issues, now I believe that I found it and I’d like in on this Class Action Lawsuit against GM…..HOW??

    • No as the 6.2’s unlike the 5.3’s have been a solid engine out all gm v8’s over the last decade.Also they had some changes after 2014.

  8. My 2008 Silverado crew cab 5.3 with AFM has the same problem with oil consumption, Since it was new I’m always checking the oil,not always but sometimes it’s low before 3k miles.

  9. I own a 2013 Silverado 1500 with the 5.3L.
    Last year in September I had a lifter collapse at 145k miles. It always consumed about 1 full quart of oil every week! I performed an AFM/DOD delete using a stage 2 can kit from TSP. Now I no longer have any oil consumption problems at all!!! Although I lost about 2 MPG, at least I’ll never have to worry about running low on oil not having another lifter collapse ever again!! Cost about $4 with everything said and done.

  10. I believe these problem actually started in the 2000 year model. My 2000 Chevy Silverado 4×4 v8 5.3ltr engine has all the same issues except mine constantly reads high oil pressure.

  11. What about the infamous 5.3 flexfuel with cylender shutdown. Failing 08 avalanch x tahoe and silverado that was a bigger failure I worked for chevy dealers since 1984. Gets me to think about if I should fix or replace engine on my avalanch x tahoe as they both sit in my yard.

  12. GM has been doing everything in their power to destroy America’s great car brands. Consider that GM destroyed Oldsmobile, Pontiac, Saturn, SAAB, Holden, Daewoo and they tried, but failed, to destroy Opel and Lotus. GM “Killed The Electric Car” EV1. GM’s Hummers are disasters. GM’s Special Ignitions Killed many Americans, for a decade. GM doesn’t stand for Gruesome Murderer for nothing, they earned it.

    • I had the weld break in my 2017 Chevy Silverado. No AC cooling. After a few weeks of studying the recalls on the Tahoe and GMC Serria but Not the Silverado I had a long talk and asked for area rep to get involved. Dealer agreed to fix for $300. Two months later I received a check in mail for $300

  14. All engines, as well as vehicles themselves are engineered to fail, so they can sell more of them. They want you to trade in every 5 years. Why do trucks rust so badly and so fast when they could use better metals? Everything about them is designed to last a specific amount of time, then fail, so you need to get a new one.

  15. My 2014 Silverado has the 6 cylinder engine and has the same problem. I bought it with 39,000 miles and its consumed a lot of oil since I bought it. Every other gas fill up I have to add oil. It now has 113,000 miles and at start up the engine has a slight knock. As it warms up it quiets down. The frame is rusting badly and the right rear quarter panel is rusting out. What a huge disappointment. Chevy trucks are designed to fail early. The seats are cheap and speakers sound aweful. Over priced junk.

  16. I have a 2006 suburban. Got it third hand. The only complaint is the headliner and paint oxidation. Otherwise the people before me never took care of it. I bought it with 123,K miles. I put all the maintenance needs in it. Pull a 24ft .enclosed trailer with it. Had it for a year. No smoke or burning oil. It has over 132k miles now with no engine problems. I like the power. It did have a dash cluster issue. But I had it redone. Maybe it was built on a Wednesday.

  17. I installed a EFM delete years ago on my 2012 Silverado Z-71 that keeps the engine running on all 8 cylinders all the time, hasn’t used oil since the day I plugged the EFM unit in.
    The need a class action lawsuit on the rear fenders rusting out.

  18. I own a 2007 Silverado that I purchased new in August of 2007. I have had no issues with the Vortex 5.3 liter engine, however the 4 speed automatic transmission has been another story. Twice under warranty I had to have the transmission fixed at the dealership and now that the warranty is long expired, the truck has been parked for several years in need of a new transmission. I just haven’t had the time or money to sink into it.
