2015 Chevrolet Equinox: misfire or rough idle

Filed Apr 9, 2026 · Engine · OH

Burns Oil so bad I don't need to change oil. I put about a quart of oil in it a week. Car runs rough. Sometimes overheating and sounds loud when low on oil. This occurs on a consistent regular basis since aquiring in October 2024

To Whom It May Concern, I am writing to formally file a complaint regarding my 2015 Chevrolet Equinox, which I purchased used approximately one year ago. Since acquiring the vehicle, I have experienced severe and excessive oil consumption as well as ongoing fuel injector problems. Specifically, the vehicle requires additional oil every 100 to 200 miles, which is far beyond what is considered normal or acceptable for a properly functioning engine. I have not noticed any external oil leaks, and there are no warning indicators until the oil levels are dangerously low. This not only puts the engine at risk of damage, but also presents a potential safety hazard while driving. In addition to the oil issue, I have experienced fuel injector malfunctions which affect the car’s performance and reliability. This has resulted in rough idling, reduced fuel efficiency, and difficulty accelerating at times. I have come to learn that many other owners of the 2015 Chevy Equinox are reporting the same issues, particularly with excessive oil consumption related to engine design flaws. I believe this is a manufacturing defect that should be addressed by GM and reported as a recall or service campaign due to its widespread impact and potential risk to drivers. I respectfully request that the federal safety agency investigate this matter further to determine whether a recall is warranted and to encourage General Motors to take responsibility for this recurring issue. Thank you for your time and attention to this matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

GM has long known about the oil consumption problem of the 2015 and settle a lawsuit for the 2013. Car issues including engine shutdowns and stalls, spark plug fouling, engine misfires, unexpected loss of power, vehicle “jerking”. Other people had the same issues included fires per blogs about the issues with the 2014-2015.

My vehicle has been having issues for a couple weeks with rough idle and my rpms reving when I let off the gas pedal. On 12/26/20, my vehicle stalled while driving it. Upon restarting it, it was making a loud noise, but no dash lights were on. I had it towed to a shop to see what was going on. The shop informed me that it had lost all of the oil due to a busted main seal. He told me that he had a bulletin that this was a common problem in my vehicle. The seal is busted because the design of my car allows moisture into the manifold which then freezes and busts the seal. It is costing me $1500 to fix the seal and clean the moisture from from the manifold. I am told that there is no way to prevent this from happening again. I am very scared that I will be driving down the road and this will happen again. I have talk to chevy, but nothing has been resolved.
