POWER TRAIN
On 4/14 with only 21 miles on the odometer in this newly purchased car the entire transmission failed, per the dealership because of a “leaking valve”. The check engine light came on after the car was jumpy and then the car refused to speed up on an extremely busy street and began locking up, putting us at serious risk of an accident. It was barely able to reach a parking lot and at that point all of the transmission fluid leaked out all over the parking lot.

POWER TRAIN
At 44 K miles, my car started giving me a message "Shift in to park" after I stopped my car and turned off the motor. I was unable to essentially shut my engine off and leave my vehicle. I called the GMC shop, where they diagnosed it as faulty wiring. It is not under warranty, therefore I will encure the cost which is not a normal item to go out on a vehicle. Also, our 22 Trailblazer is also giving us this same message.

UNKNOWN OR OTHER
Upon starting vehicle it would idle for 30secs to 1 minute before shutting completely down, then would prompt to engage brake and push start/stop button to turn back on. Two different times while driving at 60+ mph the vehicle completely stalled losing power steering and brakes. Both times when the vehicle shut down it would say to push start/stop button and then place vehicle in park, engage brake to restart. When the vehicle stalled I was getting onto a highway and was about 2 seconds from being hit from behind by a semi while I was at almost a standstill while they were doing 70+. Have taken it back to the dealership both times and it died on them once but there is no solution to this issue as no codes come up.

UNKNOWN OR OTHER, POWER TRAIN
The gear handle, when I place in park, will NOT park, therefore, I am not able to turn off my car. I have to jiggle, push start button and try over and over. This is a 2 .5 year old vehicle.Warning alert comes on stating the obvious, Unable to park! Also, it sounds like when I do drive of like the dragging, rough sound, which sounds like the gear is not fully in drive. Again, this is a new vehicle. It is unsafe and getting worse. Thank you.

The check engine light and other error codes are on. The vehicle would run fine and then the engine would go into 1/2 power and go slow while driving. This has happened other times too. It has been in the shop and the dealership and GM do not know what is wrong with it. It has been there for almost 2 weeks.

SERVICE BRAKES, FUEL/PROPULSION SYSTEM, ENGINE
The ABS system in this vehicle flashes warnings at quick restarts and while holding the brake down, it has no “sponge” when this happens. The brakes squeal constantly. I’ve had them inspected at every single maintenance and there can be no flaw found. When driving on the interstate, the engine is very “jerky” almost like the transmission can’t keep up with the speed of 70-80mph (not always, but it is noticeable when it happens). At first I didn’t think much of it but with the mass recall of chevys identified, I believe it needs to go on record - particularly about the brakes.

STRUCTURE:BODY, UNKNOWN OR OTHER
I could turn off the engine after driving, but the key stays in the position between the engine being on and the car being off (for example when you can listen to music but your car isn’t running). The battery light came on after the issue started and so the car service place charged us to replace the battery, because they had to turn on and of the car a lot and the car had to continue to run. I took it to a car service place and they ran tests and called Chevy test support to run diagnosis tests. They can’t figure it out. They think it might be the body control module. Not sure what that is. The car only has 31,000 miles on it and this is a safety issue because what if this happens and the steering wheel locks or it becomes a rolling hazard. This would affect the driver and others. There were no lights or errors indicating a problem before this happened.

Alert for shift to park keeps alerting after already in park. I have to turn car on and off at least 20xs to get notice to shut off . I cannot leave car with notice on dash screen or it will beep at me and drain battery. I went to service at Chevy and they told me this isn’t a recall and the part I need is a new shifter and it will cost me money on a 3 yr old car to fix with 14000 miles. I am extremely upset because the part is unavailable and no estimate when I can get it fixed. I’ve been dealing with this for a few months and it take me 20mins off and restarting to get error to go away. I need answers !

VEHICLE SPEED CONTROL, STEERING, SERVICE BRAKES
Two times in a month after getting fixed the first time the esc error code pops up and the engine starts running at 1/2 capacity and the steering gets hard to steer. There is also a braking error code that displays. I have had to tow it to the dealership twice now and can not drive it. It is a danger since it will decelerate when in traffic and becomes hard to steer.
