GM named in class action lawsuit over excessive oil consumption in Chevrolet Equinox vehicles

General Motors

 

This class action pertains to Model Year 2010-2017 Chevrolet Equinox vehicles with 2.4-liter engines. These engines were denominated within GM as the “LAF” and “LEA” engines (also referred to herein as the “EcoTech 2.4L” engine).

 

As alleged, GM knew that these vehicles contained one or more design and/or manufacturing defects that cause them to be unable to properly utilize the engine oil and, in fact, to improperly burn off and/or consume abnormally high amounts of oil (the “Oil Consumption Defect”).

The primary cause of the Oil Consumption Defect was the composition and construction of faulty piston rings, including both “compression” and “oil” rings. In particular, the composition of compression rings did not permit these rings to withstand the higher compression ratios of the LAF and LEA engines, in that the coating would fail and cause premature ring wear, and that these rings were too thin. Additionally, GM installed low-tension oil rings in these engines that do not maintain sufficient tension to keep oil in the crank case within design specifications.

Included in the EcoTec 2.4L engines, which further contributes to the Oil Consumption Defect, are spray jets that spray oil onto the piston skirt and cylinder wall. This was not common on other engines with adequate piston rings. This oil spray overloads and fouls the defective piston rings, triggering oil to migrate past the piston rings into other places in the engine. This excess oil either burns off or accumulates as a carbon buildup on the combustion chamber’s surfaces.

The complaint also alleges that the EcoTec 2.4L engine includes a flawed Positive Crankcase Ventilation system that vacuums oil from the valve train into the intake system, where it is ultimately burned in the combustion chambers.

The engine oil defect can cause a myriad of issues creating a safety issue including:

  • Sudden engine shutoff, resulting in loss of power, loss of braking, and inability to adequately maneuver in high-speed or congested driving situations;
  • Driver distraction due to sudden and unexpected engine shutoff, caused by sudden loss of power, illumination of warning lights and sounds, and loss or diminution of power brake assist;
  • Loss of maneuverability in high-speed or congested driving conditions due to unexpected loss of engine power—even when the engine does not shut off;

I have the same issue with my 2014 Equinox. It is currently at a mechanic's because it completely shut off on me driving to work a few nights ago. I have been noticing that I needed to change the oil more frequently and have been told many times by the dealership that "it's normal with this vehicle".

I have a 2012 Equinox that I purchased brand new and around 75,000 miles I noticed a ticking sound in the engine and took it to the dealership that I bought it from and who has done all the routine service on it since it was new. The vehicle was 3 quarts low on oil and I did not receive a warning and it wasn’t even close to due for an oil change. Since then, it has been consuming probably a quart of oil every 500-700 miles and the ticking has never went away.

Our equinox has had this problem ever since 50,000 miles. It shuts off out of nowhere, rocks back and fourth when at a stop. There is a ticking noise and is very dangerous to drive. We have to put oil in it every week now about every 200 miles. We had all the maintenance done accordingly but that has not stopped the problem. I cant believe there hasn't been a recall on theses vehicles.

I have had this problem since I purchased my 2011 Chevy Equinox. It consumes so much oil I have to put oil in it every 200-300 miles. I have had the oil changed early and often. If I didn’t add oil it would have been blown by now. . It makes a loud noise on startup if it gets low. It will act like it’s going to stall. And has stalled a few times. I have had the consumption test done and it showed there was a problem. They did their “fix”, but it still has burned oil at an alarming rate. The fix they supposedly said would work doesn’t. And there has never been a low oil pressure warning light. They extended the warranty for about 20000 miles but it never fixed it to start with.

My 2013 Equinox is going in to have the engine “rebuilt/ fixed”after going through the 1,000 mile test because no longer under warranty and took it in when under warranty but “NOTHING FOUND WRONG” although there was most definitely something wrong... and GM is going to give me $700 toward the $2,250 cost and will “ONLY” cost me $1,550 to have GM fix/rebuild my engine at 82K miles and 2 more years of payments left. How generous of them!

I have a 2013 GMC Terrain and I have the same oil consumption issue. GM refuses to replace my blown motor due to oil consumption because I'm outside of the 120,00 mileage they are willing to cover. I was also told by GM customer service that even if my vehicle was within the mileage parameters I still wouldn't be covered because a oil consumption test cannot be performed on a blown motor. Someone please get us GM Equinox and Terrain owner's a damn recall already!!!!

I have a 2013 Chevy Captiva and was shocked when I was told myoil lecsl was dangerously low. I’ve always kept up with oil changed but the car was running rough and stalling out and just wasn’t right so I took it in thinking it was a bad cam shaft sensor as the engine code read. Was told to take it back to Chevy and repair was basically a new engine and 20 hours of labor.

My engine just failed because of this. I have a 2010 Chevy Equinox with 108,000 miles on it. The car isn't worth saving but this is going to start happening more and more to customers with Equinoxes. Rattling in my engine started happening in November, once I put oil in it was fine. Once my oil was at 25% my engine starting shaking (on monday). By Wednesday the engine was dead. Dangerous situation.

I have had the same issue with my 2014 GMC Terrain. I had a synthetic oil change on 12/17/18 and on 2/16/19 my engine completely shut off without warning on the highway. It then flashed engine power reduced. After having it towed to our mechanic he said the motor was blown due to a host of problems caused by no oil at all left in the vehicle. No oil lights have shown up prior to the engine problem.

My 2014 Equinox that I've had for 2 months is broken due to faulty pcv valve, consequently the seal broke, and then the piston is now broken. I just bought this car. I'm struggling just to pay my bills and now I don't even have a vehicle to drive. GM won't repair it although I bought the warranty.

I own a 2011 Equinox, having had the throttle body replaced only 3 months after purchase.. it also had high oil consumption, using a quart a week. I have had to have the balancer belt and timing chain replaced in November, and now 4 months later, I have a blown motor, it sits at the dealership because it will cost 7,600.00 to replace the motor, which is more than the car is even worth. Debating on where I go from here. I have already thrown thousands of dollars at this car in repairs...this car has been nothing but a nightmare

Same issue. 2 quarts every 500 miles. No warning light for low oil. Pcv system froze solid and blew out the rear main seal. Cost more to fix the car then we bought it for. Second GM vehicle I own in less then a year to have a catostofic failure due to faulty parts/software. Gm has cost me over 20,000$ in 2018/2019

Purchased 2011 Equinox 2.4L brand new in 2011. Noticed excessive oil consumption almost immediately, having to add a quart between oil changes. Was told this is normal. Has been happening entire time and now I have excessive engine noise with startup. Naturally, the drive train is beyond the 7 year warranty period (and at 110,000 miles). The only time I was offered an oil consumption test was prior to driving from FL to NY and I was unable to come in for [known] results [of oil consumption].

2 quarts every 500 miles. No warning light for low oil. Only GM vehicle I have owned, only GM I have ever owned. I am petrified to drive and constantly checking oil level AND carry quarts of oil with me. Oil changes for what? There is no oil to change because it burns faster than fuel. Scary that nothing has been recalled.

2013 Equinox was burning 2 / 3 quarts every 5000 miles. Mechanic advised us not to follow oil consumption display on dash and change oil at 50 % oil life.
I followed his advice last two oil changes. Last week my wife was driving home and the engine went into low power mode. She drove the car home ( -about 5 miles ). I had the car towed from my house to local dealer. ( $95.00 ). Dealer checked issue and found rear main seal failure caused oil leak and lower engine failure.
Dealer quote to replace engine was $8100. I declined cant afford cost at this time. I had the car towed back to my house, another ( $95.00 ) towing fee plus a $65.15 dealer charge. I now have a clean looking 2013 Equinox parked in my driveway that needs an engine I cant afford. So frustrated!!!.

I just got a 2010 chevy equinox with 2.4 motor in it back in may 2018 which it had 107××× mile on it and now there are about 124××× mile on it, and i realized that I've been burning oil alot. A couple time when went to get the oil change they told me there was no oil on the dip stick. i made it a habit to check the oil every other day just to make sure there was oil in there. I just recently had to replace the 4 fuel injector in it because of the oil in the them and before that the throttle body I had to replace. I have a thing of oil in my car just so I have some when it gets low. As of right now I'm in the process of the dealer ship doing the oil consumption test where I go back every 1000 miles. Got results back from the oil consumption test 3qrts low within 1000 miles. Warranty will only cover it if the dealership tears it apart and it's a part that's on the warranty list if not I have to pay for it. Not sure whatvtondonat this point! I feel like I've had nothing but trouble since I've got it and It hasnt even been a year since I've had it and the loan for it is for 5 years!

Same here. Burning oil like crazy. Truck throws the P0521 code more and more lately. Replaced the pressure sending unit and screen a few weeks ago just to be sure that wasnt the issue. 2013 Sierra with only 58,000 on it. Never really had an issue until the last few oil changes. Mobil filters and conventional Mobil 5W-30 like I've been using for years. My next vehicle will certainly NOT be a GM product.
