I was driving my vehicle on the highway when all of a sudden I started to lose speed and my car wouldn’t accelerate. When my vehicle wouldn’t accelerate it started to shake significantly and the check engine, abs, traction control, and service stabilitrak light came on all at once. I was able to pull over and get my car towed to the dealership. Once it was at the dealership it was diagnosed that my car had jumped time causing a misfire in cylinder 4. My dealership stated this was due to low oil and my piston had become warped due to making contact with my valve. My car had no check oil warnings or any indication that vehicle was low on oil prior to this happening. My vehicle drove perfectly fine until that point. My vehicle also had no oil leaks (confirmed by myself not seeing any leaks under my vehicle as well as the dealership when they did the diagnostics). Before I bought my vehicle I did research and knew this model vehicle had oil consumption issues, so I made sure to routinely check my oil levels. Even with getting oil changes approximately every 3,000 miles and checking my oil levels and topping off my oil whenever it got less then 5 quarts I still had to get a total engine replacement. This was a huge safely issue since there was no warning that my oil was low and my car lost speed on the highway and was trying to stall out before I had a chance to pull off to safe place.

When temperatures were around 0 degrees, I was driving to work and I started hearing a noise and the car was shaking. I oil all over the ground and checked the oil once parked, the dip stick had no oil and there was white foam under the oil cap. This issue could've cause me to lose control of my vehicle while driving, putting myself and anyone around me at risk. I had the vehicle towed to a dealership where they found out that the rear main seal failed. They replaced the rear main seal along with the front main seal and sent me on my way. I had no issues for the next month, but the weather went back below 0 degrees and the same issue happened again, this time there was ice found in the intake manifold. This repair is being completed now. The vehicle has not been inspected by anyone other than the dealership. No warning light, messages or any other symptoms were present prior to the failure. The engine light DID NOT turn on when the seal "blew" but did turn on after turning the car off and back on.

Make: Chevy ---- Model: Equinox ----- Year: 2016 ----- Mileage: Just under 78,000 miles ----- Component or system: Rear main seal failed leaking nearly all the oil left in the vehicle over the course of a few minutes of driving, which also left a dinner sized plate of oil underneath the car after parking in my garage. ----- Available upon request: Incident occurred 1/14/2025, with diagnosis from dealer on 1/15/2025. As of this moment the vehicle is still available and is being held by the mechanic while I decide on next course of action (repair or scrap). ----- How was your safety or the safety of others put at risk? I luckily made it home before all of the oil had depleted but this could have caused engine damage and failure while driving. The repair shop noted they did not notice any signs of engine damage but they are worried that engine damage may have occurred. There is no warning on the dash or computer related to the seal breaking or oil being almost entirely depleted. ----- Has the problem been reproduced or confirmed by a dealer or independent service center? It was brought in to a local repair shop who I personally trust which also has a 4.8 stars with 700 ratings on google. They degreased the car due to the oil everywhere and noted the rear main seal on the car had a massive leak and the car is non-operable in this condition. ----- Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Vehicle has only been inspected by the dealer mentioned above. ----- Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There is no warning or check engine light on the dash or computer related to the seal breaking or oil being almost entirely depleted.

Maintained vehicle with regular oil changes, tire rotations and inspections. Last oil change was June of 2024. Minimal driving throughout summer as both drivers are teachers and home most of the summer. Vehicle engine light illuminated on 9/12/24 with no prior issues or lights illuminating. Vehicle then went into what felt like "limp mode." Vehicle was taken to certified Chevy dealership service center. Initial diagnosis indicated there was little to no oil left in the engine. No visible leaks were seen on driveway where it has been parked, no smell of burning oil occurred prior to engine light illuminating. Oil life monitor stated 65.89% remaining. Visible leak diagnosis passed inspection. Diagnosis of misfire/engine related concerns. While on phone with mechanic it was stated that pistons and rings were malfunctioning. Upon researching issues, I discovered that there is a well known issues within GM of this exact problem existing in which around roughly 90,000 miles (my vehicle is currently at 91,000+) this specific engine starts consuming oil at a massive rate without indicating any leaks or smells of burning oil. Service center quoted between $6500-$10000 to repair. After I provided feedback about what I had discovered, I was told by mechanic that this is a well known problem with this vehicle. Extended warranties for this issue has been issued however, I am being asked to cover the cost to repair a known problem within the 2011-2017 GM engines in the Equinox and Terrain models.

My chevy equinox 2016 2.4L vehicle engine signal went on. Two days after the light went on, my vehicle stopped on my way to a dealership to ask for assistance. In the early years of purchasing this vehicle everything was working smooth. After the first 3-4 years I remember the mechanics asking if I had done my oil changes, and the answer was yes every time. Now that I started to look further into the issue Im finding out that this exact engine burns through oil way too fast and has cause issue like engine going out. This is a big issue for others on the street and myself, thankfully I was not on the highway at the time when the vehicle shut down on me but I am constatnly utilizing the highway to get around town. This can easily cause an incident in any road/highway if the vehicle had shut off at the wrong time and wrong place. The vehicle has not been inspected for the reasons I'm stating here, but have been noticed by mechanics when doing maintenance. I did not think much of it because I am not a mechanic and I just thought that was the normal for a vehicle to do over time. Now I'm getting quotes to replace the engine plus labor can run anywhere from 6-8 thousand dollars. There was not any warning lights or anything in regards to the engine earlier on, this happened a few days ago and shortly after my vehicle gave out. The engine light never flashed either, it would just stay illuminated, and from my understanding that's a warning to take it to a mechanic shop for further inspection. The amber engine light that im aware of is to not move the vehicle and get somewhere safe.

The vehicle burns oil causing engine failure. This issue occurs without warning (no oil light, and the check engine light appears moments before the vehicle dies). The vehicle burns oil and reaches engine failure even when regularly scheduled oil changes are completed. THIS SHOULD BE TAKEN SERIOUSLY AND RESULT IN A RECALL.

[XXX] I drove to work 9.8 miles. It was very cold that week, Zero temps. During my drive I experience intermittent power surges/loss, horrible exhaust filled the vehicle to the point I had to open windows. NO ENGINE LIGHTS ever came on. I called repair shop and scheduled to bring it in after work. They notified me that the main rear engine seal had blown and caused the oil to leak all out and ruined my engine. The cost to repair/replace engine is going to be $6k. This was a very dangerous situation. I often drive with my daughters and grandchildren in my vehicle. We could have been in a serious accident if I had lost power on the freeway. Or, could have been stranded on the side of the road in zero temps. Upon researching this issue, there is an ongoing lawsuit, , et al.,[XXX] v. General Motors LLC.Case [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
