I purchased a 2012 Chevrolet Equinox with 100,550 miles on it in April 2023. The original owner gave me all service receipts & records to show the automobile had been taken great care of. The interior & exterior are still in like new condition. The problem I've experienced is sudden "reduced engine power" that caused the engine to stall while driving. Two weeks prior, I had had a service check with an oil change and the works. I had it towed and to my surprise, the mechanic showed me that my automobile didn't have ANY oil. The oil indicator light NEVER came on. Afterwards, I did research and discovered that GM is aware of this exact problem in this particular make and model and been sued in a class action lawsuit for this and lost. WHY HAVEN'T THEY ISSUED A RECALL TO REPLACE THE FAULTY PISTONS THAT CAUSES THIS?

The car was in motion when the reduced engine power sensor came on and shut down. It was towed to a local repair shop where it was determined that the timing chain broke due to lack of oil due to bent piston rings and the oil escaping. All of that was repaired and maybe 6 months later the check engine light was back on. We took it back to the shop and it was decided there was extensive damage done to the engine based on the previous oil consumption issue. The engine was then replaced as well as the ECM board due to oil being all over it completely ruining the sensors. We also have had to replace the evap system due lack of oxygen and the car constantly chocking out while in motion and while ideling. We filed our claim when the class action lawsuit came out and of course we're denied, just like the thousands of other people due to there being 'lack of proof' that it was due to lack of oil. I was constantly checking my oil, getting it changed, adding the right oil when it was low and because I did not do the oil consumption test through gm we are out almost 10 thousand dollars on a car that still had issues due to the lack of oil. The first time it broke down I had a power train warranty on the vehicle and they did an investigation to make sure it was due to a lack of oil changes and build up of dirty oil, it was proved that the oil escaped through the bent piston rings and burnt off instead of going back into the engine. They did cover the timing chain but once the engine needed to be replaced we no longer had the warranty. I'm not sure why that investigation was not good enough for the settlement to go through but regardless these vehicles are so unsafe and money pits and are still being sold to innocent people who have no idea what they are getting themselves into. A recall absolutely should be made.

While driving my 2012 chevy equinox on illinois, I-90 at 70 MPH vehicle started to lose power. Engine could not accelerate, started shaking, than stalled. Putting myself & family at risk & in danger. Engine needed to be replaced or rebuilt, had it rebuilt. Gm is aware of their faulty engines but continues to sell these cars and put families at risk. They lost a lawsuit but continue to deny claims & resell the faulty vehicles. Waited almost a year to be denied. These vehicles with the faulty engines need to be pulled immediately & consumers need to be reimbursed for the cost of fixing gm's mistakes.

Driving normally about 35 MPH on suburban road when dashboard suddenly indicated "service power steering." the steering wheel seemed to lose all power assistance and was strenuous, even dangerously resistant, especially when needing to turn in front of oncoming traffic. Arrived home and check the power steering fuse, which was okay. Next day steering was back to normal power-assist and dashboard indicator message was gone.

My wife was driving down the highway and she received a warning stating 'reduced engine power' and 'service stabilitack'. Wishing a few seconds of this her car died on the highway and would not start back up. Upon initial review the pcv line was blocked with ice as it was single digit temperature. When I checked the oil level there was nothing. The oil light never came on according to my wife. I put 2 quarts of oil in the car and it started back up, however it barely made it 4 miles back to the house before the oil was gone and the undercarriage of my vehicle was smoking from the oil coming out. This is exactly described in bulletin 14882. My car has just over 107k miles and appears meet all criteria of said bulk item. However, upon speaking with chevrolet about this bulletin. My car is not covered.
