GM Oil Class Action Lawsuit Consider The Consumer

Advertising & Reviews

GM Oil Class Action Lawsuit Investigation Commences

There have been a number of complaints concerning Chevy Equinoxes and GMC Terrains, in that they are consuming oil much more quickly than they should be. Some consumers have even come out to say that the cars need one quart of oil for every 1,000 miles driven. Due to these complaints, numerous lawyers have taken action against GM, which may lead to a potential GM Oil Class Action Lawsuit. reports that although GM has already been hit with class action lawsuits over the oil consumption issue in certain Chevy Equinoxes, more people are needed to come forward to help strengthen the case. Furthermore, a lawsuit has not yet been filed for GMC Terrain drivers, so these people, in particular, are needed to speak up. If you had problems with the oil consumption in your Chevy Equinox or GMC Terrain, fill out the form on this page and tell us your story.

Were the Cars Recalled Over the Oil Consumption Issue?

Unfortunately, no official recall has ever been issued. In July 2015, however, the company sent out a service bulletin titled “Special Coverage Adjustment – Excessive Oil Consumption.”

The service bulletin concerned 2011 Chevy Equinox and GMC Terrain vehicles with 2.4L engines. It warned that these cars could “exhibit excessive oil consumption (less than 2,000 miles per quart of engine oil).” Additionally, the service bulletin noted that:

“If this condition is present, the oil can light may illuminate on the instrument panel or the following message may appear in the Driver Information Center: ‘Oil Pressure Low – Stop Engine.’”

The notice instructed dealers to replace the four piston assemblies on the 2011 models at no charge to the customer. No such fix, however, was ever offered for the other model years. 

In fact, consumers have complained that GM’s only policy for the other models is to have the customer bring in the car every 500 miles for an oil check.

What Problems Have Consumers Reported?

Drivers have posted a number of complaints online about their cars burning excessive amounts of oil, stalling, shutting off while driving and other issues.

How Could a Class Action Help?

In a successful case, a class action lawsuit could help drivers and lessees get back money they spent on:

  • Unreasonably frequent oil changes
  • Oil purchased to be carried around in the car “just in case”
  • Inspections, diagnostic tests and repairs to their car
  • Loss of the car’s value

Plus, a lawsuit could order GM to replace the engines in the affected cars.

  • Bob Schomer says:

    We Aldo’s have a 2012 Terrain. After numerous visits to the dealer, where we always have out oil changed they fixed he problem charging us half the cost. I knew if they went half with us they knew it was a problem, but we needed it repaired.

  • Sherril says:

    What years have been reported. Just bought a 2017.

  • Joe Romp says:

    Just bought a 2015 Equinox,2.4 L any problems with this vehicle?

  • Derek says:

    They need to look back even further, my 05 silverado burns 1 qt per 1000 miles, and has since I bought it with 80k on it.

  • April Maines says:

    What years are affected and what engines? I have a 2012 terrain with a 3.ol

  • r ditmore says:

    i have a 2014 sierra 1500 5.3 that uses oil as well.warning chimes come on at around 2500 miles after oil change. dealer just blows me off. i have been a mechanic for over 30 yrs. never have i seen such crap

  • Robert Roll says:

    i have a 2012 Chevy Equinox LTZ… have the same issue present was doing it before the 140,000 mile cut off from the warranty letter even took it to a dealer for the same issue and they told me the oil was low. now after 140,000 miles i get this recall letter but since the car was over 140,000 miles they wont touch it because i didn’t have an oil consumption test done when i took it in before the cut off … and how was i suppose to know to do that?

  • Audrey Foster says:

    Please help. I am having same problems.

  • Mandy says:

    I have a 2011 Suburban that had oil consumption beginning at 55k miles and dealership did a “try this part see if it works” of course didn’t & now over warranty, then had to pay to have bottom half of engine rebuilt at 60k miles, and then had to pay to have whole engine replaced at 72k miles. I keep hoping to find a class action on the Suburbans as well, I would be more than happy to get some of my money back – the problem I have is that two dealerships new this was an issue and that they even offered a “try & fix” for it just to hopefully push it passed the warranty which they succeeded –

  • Christopher Hawkins says:

    Chevrolet replaced the engine in my 2013 Chevy Equinox due to excessive oil consumption. The first time they “fixed” it, they simply replaced the pistons and rings. This didn’t fix the issue so they replaced in engine in July 2018 when it had 100k miles.

  • Terri Schimelpfenig says:

    GMC would not cover or replace my engine in my 2010 GMC Terrain. The Timmy g chain guide broke and there was piston to valve contact that caused severe internal engine damage. Cost me over $4000 to put in a new engine.

  • Robert Barber says:

    I have a 2013 and Just had the oil changed and never had this happen. Car started julerking and trying to die and checked oil and didn’t even register on the dipstick. Added 2 1/2 qts and now it’s full but has only been 2000 miles since oil change.

  • Randt says:

    Need to check and start a lawsuit for the frozen pcv valve issue also.
    GM answers .”your Vin is not civered”.

  • Joe Romp says:

    What year, model,engine size has pcv valve issues?

  • Jerome Brandon says:

    I have a 2013 GMC and I had to get an oil change every 1,000 miles. The oil light never comes on and you would never know unless you felt the car start to jerk. It’s a travesty you have to file a class action law suit for something to get covered for your vehicle. This is absolutely terrible on GMCs part . My car now died due to this fact and my mechanic is trying to replace head gasket and cilinders to correct this issue .

  • Tom Cowan says:

    “Purchased vehicle. It was smelling and knocking although it had had a recent oil change. It was alarming that the engine light never indicated a problem. Checked oil, had to put quarts of oil in. Had to check it regularly (every other day) to see if there was a leak or problem that would result in the engine being blown. From this observation we found we had to add a quart a few times a month. We were sure to use the oil required although it is more expensive. We ended up purchasing the oil in cases. We tried to drive it as little as possible. It was very stressful and went on for a considerable amount of time. Finally the recall occurred. Once the recall repair was completed, we continued to check the oil consistently.”

  • Will never buy another Chevy, purchased a 2012 in October 2017 Chevy Equinox had to replace engine (January 2018) because oil had burned out and panel never indicated oil was low. Still have to check oil weekly because of oil consumption. New problem – Wiper transmission, had that repaired plastic band broke, within 6 weeks have to replace total wiper transmission. Was told by mechanic next time “Don’t buy American cars they are pieces of Shit”. Buy a Toyota. This is a shame I want to keep us (Americans) working but, quality is no longer a priority in this country, just screw us and take our money!

  • Tammy Wilson says:

    Bought a 2011 Equinox in April, had it in the shop for multiple issues with extended warranty. putting oil in it every couple days, stabilitrak light and traction control lights stay on. The special coverage expired 6 days before I took it in, had no idea there was a known issues with the bad piston rings.. The car lot I bought it from and I paid Chevy 5000.00 to fix it. Came back still stalling and lights on, took it back again, still lights on and now they wont fix it… Need an Attorney!!

  • Mackenzie Vaughn says:

    We bought my 2010 Chevy Equinox about a year and a half ago.
    I started having issues with the vehicle shortly after purchasing it. We took it to a shop and they told us it was a bad fuel injector and the harness needed to be replaced. $2000 later, find out it is an oil consumption issue.

    I had an oil change less than a month ago and my car has already burned through all of that oil in less than 1000 miles and my engine is still on.

  • Mike Baniak says:

    2011 Terrain goes through 3 qts between oil changes. My catalytic converter is now clogged due to the excessive oil going through exhaust system. 1250.00 for repair!! GMC said there is no recall for this particular problem?!?! Really??? What a joke!!!

    Unfortunately we are all stuck with a worthless vehicle, but on the bright side we are keeping the oil manufacturers happy!

  • Michelle Linkous says:

    Bought a 2013 Equinox a year ago it now has 55,000 miles on it. It broke down on me and would not start back up, had it towed to a Chevrolet dealership on January 25, 2019 and as of today still no answers as to them covering it. Technician said motor needs replaced. I have been paying for a rental car for going on 2 weeks and no answers yet.

  • Jamie says:

    I have a 2013 Chevy equinox that only used oil one time but checked it frequently after that and a few months later choked up three times and died leaving my daughter and I on the side of the road I’m freezing temperatures and I am being told blown engine and 5700.00 to fix it. Cars are junk and GM needs to step up and back it or I will never own another GM product as long as I live. I have been in contact with GM case number 9-5047291041 and basically told me to take it to a Chevy dealer for diagnostic testing and if something warrants it is their fault they will get in touch with me. I’ve read several posts on several sites and there are thousands of people with this issue!

  • Amy Babb says:

    My 2013 Chevrolet Tahoe has this problem. My husband’s 2008 GMC Sierra had the same problem and we had to have the engine rebuilt. Both problems started occurring around 120,000 miles.

  • Terence Johnson says:

    I have a 2014 GMC Terrain a while my car showed the oil life at 48 Percent there was oil in the engine and blow a main seal now I am stock with a worthless car

  • Rodney Damon says:

    My 05 uses oil a qt every 900 miles

  • Christopher Richards says:

    2013 Chevy equinox 125,000 miles bought it from a dealer ship thought we got a great deal car looked brand new 1 owner car had I a month now and today it cuts off at a red light started right back up and stalled a little bit but the took off strong got to next light stopped and it seemed fine took off from that light got half way throw light and shuts off the car behind me liked to hit me I had to struggle to get the wheel to turn to get off to the side put it in park cranked right up fibe called husband he drove it home it cut off 3 times with him and that’s how I found out about all of the problems it’s got less the 500 miles on a new oil change and when he checked it nothing not a drop o. The dip stick GM needs to be punished severely for this it can kill you and your family and they knew it and I’ll be calling my own lawyer tomorrow not for money but to make this a recall on all the Chevy 2.4l ecotec engines

  • Renee Poole says:

    Our 2012 Terrain stopped on a 55 mph road. We had to tow it to GM, biting fingers $$. Done with American made, very sad to feel like you have no recourse. God Bless America!!!

  • Billie Jolley says:

    I have a 2011 GMC Terrain. It has used massive amounts of oil since I purchased it in 2015. Although it has gotten low on oil prior to being due for an oil change, the “low oil” warning light has never came on. I have taken it to the Certified GMC dealership several times only to be told that they can’t find anything wrong with it. It has broken down 2 different times in the middle of heavy traffic, scaring me and my family, as we tried to maneuver to safety. The motor bogs down and gives a “loss of power” warning, the check engine light comes on, the traction control light and warning come on, and the SUV dies as you are going down the road. I just got the news today that I need a new motor because it has jumped timing. I have been advised that my Terrain does have the EcoTech 2.4L engine that is mentioned in the class action lawsuit and I do plan to get involved. I do not have $6,000 for a new motor nor do I have money to waste on a monthly vehicle payment for something I can not drive.

  • Mike Ludwig says:

  • A. Rankin says:

    I purchased a 2013 Chevrolet Captiva Sport LTZ in November 2018. I have never had problems with my previous vehicles, both Ford and GM. However, I am having the same issue like everyone else. Captiva’s have the same engine. I came close to destroying the engine when it started making a noise that I thought was due to the gas I put in. I got my brother to check it out for me and it had no oil in it. I was darn lucky that I didn’t lock it up. I had the oil changed on March 8th and on May 21st I check my oil and it had mostly disappeared; took 4 qts. to fill it up. Had no idea where the oil went as I didn’t see any oil spots on driveway or at work where I park my vehicle. My brother told me to get Lucas Engine Oil Stabilizer to slow the leak. I had a mechanic to check my vehicle out and he said oil was leaking slowly around the rear main seal. Great! I really need that. The Captiva should be added to any lawsuit because I have investigate the situation and there are a lot of complaints on
