Okay, I can press the gas and try to go one speed.And my car will go either way, too slow for that gear or way too fast.For that gear , I have almost been several wrecks , because it's either going too slow , went when i'm supposed to be going to certain speed or it's going to fast one supposed to be going to certain speed

This is a periodic occurance when going starting at 0mph at any point during a trip. Normally the engine will rev smoothly but there are times when going from a complete stop to getting to at least 30mph it feels as if the engine is just taking in air and it just revs up and the car starts to roll but doesnt actually accellerate properly and this can result in an accident if you have to move suddenly to avoid being hit. I have the lt1 model specifically.

The engine loses 1% of its oil every 20 driven miles. GM knows about this excessive oil consumption and refuses to resolve the cause. I bought this as a new car, with 2059 miles on it. Right now my oil gauge reads 96%, or a 4 % oil loss, after 80 driven miles. I am deathly afraid to take this car out on a interstate highway with high speed traffic because this will really stress the engine. The 1st 80 driven miles was on city streets in orlando, fla. What I don't understand is that NHTSA has known about this GM engine problem since 2014, so why hasn't something been done to get GM to put safe, reliable engines in their cars? Their opel cars have excellent reputation for engines which do not lose oil between oil changes.I also am aware the Daewoo block has been re-worked and GM wants to get its investment back, using ultra cheap korean labor, where the engine is made. …

The manufacturer was not made aware of the failure. The failure mileage was approximately 59,392.

This report concerns a known CVT defect and subsequent TCM failure that left the vehicle unsafe and inoperable. The vehicle suffered internal CVT failure consistent with GM Special Coverage N192271110. After the first transmission failed in May 2024 (and the second time October 5 2025), the TCM failed again shortly after the second failure-consistent with GM Preliminary Information Bulletin PIP5525A. Critical Safety Details: Both failures occurred while driving on highways with heavy traffic, where speed limits were 75 mph. On each occasion, the vehicle lost power and became unable to accelerate safely, presenting a serious safety risk to me and other drivers. GM is refusing coverage despite widely documented cases and their own bulletins describing this exact failure chain.
