Noticed knocking in the engine and excessive oil usage. I keep my vehicle maintained. I went and had the values and seals replaced around engine for oil. Not even two to three weeks later knocking again. Took it back and engine is burning oil. Read about this make and model having defective pistons and rings causing oil to burn excessively. This has cost me thousands of dollars and it's still not fixed.

My daughter, the driver of this vehicle, noticed a noise. The check engine light came on. Over a short period, the noise from the engine progressively worsened. We brought the car to a certified mechanic. The mechanic's initial determination was that the engine would need to be replaced. It was determined that the engine was faulty, failing due to oil leakage that led to excessive oil consumption. As we were not ready to make that kind of financial commitment, we asked him if there was another option. We were instructed to check the oil frequently. We did so over the next couple of months, but the problem continued and worsened. As my daughter was driving, the engine would make a noise and lose power. Eventually, the vehicle started shaking and would shut down when stopped at red lights and stop signs, requiring the engine to be restarted each time. We then brought it back to the mechanic, and the engine was replaced with a new one.

Excessive oil consumption leading to a broken engine

Filed Jan 12, 2026 · Engine · TX

The 2015 Chevrolet Equinox equipped with the 2.4L Ecotec engine has been reported to have excessive oil consumption due to several issues: Defective Piston Rings: The oil control rings are prone to sticking and clogging, leading to oil blowby and excessive consumption. PCV System Issues: Problems with the Positive Crankcase Ventilation (PCV) system can create excessive vacuum in the crankcase, contributing to oil consumption. Timing Chain Problems: The timing chain can stretch over time, leading to misalignment and potential engine damage. Regular Maintenance: Owners are advised to monitor oil levels frequently and consider using synthetic oil for better performance and longevity. These issues can lead to significant engine wear if not addressed promptly. My vehicle is using too much oil. The 2.4L eco tec engine is installed in this vehicle. The Chevrolet dealership in Rockwall Texas texted me that the engine is bad and needs replacing. The vehicle is past is warranty, so the dealership is using that reason, to not fix this issue. The estimated cost to replace the engine is approximately $11000.00.

My 2015 Chevrolet Equinox has a cracked exhaust manifold, a known issue affecting many vehicles of this model. When using the heat or air conditioning, gas fumes enter the cabin, creating a serious risk of carbon monoxide exposure. I regularly transport my two young children in this vehicle, and we are forced to drive with the windows down in cold weather to reduce the risk. The vehicle also consumes oil and is still being financed. Despite the manufacturer being aware that this is a widespread problem, I am being quoted nearly $2,000 for the repair. This poses an immediate and serious threat to the health and safety of my children and myself.

excessive oil consumption 1qt per 600 miles

I just purchased the vehicle she hadn't even driven it 2 months when it started to shut off on it's on. Causing very dangerous situations. Then the oil consumption problem that's been well known and heavily documented time after time. Without warning lights or low oil pressure light or even a check engine light to give any type of warning the front seal blew out causing heavy oil loose that caused the engine bay and over the bottom of the vehicle drenching areas that have really high temperatures that could have caused the oil to possibly ignite at any time from the high heated areas that was covered in oil. Also with front seal blown out without warning led to timming chain becoming faulty and then breaking leading to my valves impacting with pistons because this is a interference engine. The impact caused every valve to bend which led to no compression and without compression no engine will start without compression. All this consumption issue is due to piston rings that are under sized which allows blow by leading to consumption. After all that the price of everything to be fixed at home by myself cost almost $1000 and many man hours not including all the time I have a vehicle that's new to me that I haven't been able to drive but just a few months after purchasing. Checker knows these problems exists and how dangerous these problems can be. You would think a car manufacturer as big as Chevrolet and GMC would do something to help there customers rather than not even showing any kind of care really in the world. I thought these companies stand by there products.

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)
