Power Train, lane Departure, forward Collision Avoidance
08/30/2026
Sudden slamming on the brake automatically when in reverse and there is nothing around the car to cause this. Has happened many times The car will alert that something is too close when turning right by there is nothing there. It is intermittent. When you start the car it the motor reves up very high and will stay there until you push the gas and then it quiets down. This is usually the first start of the day. High and rough idle Super hard intermittent transmission shift or down shifting while normal driving. It jerks really hard and sometime it’s so hard it throws you forward like the brake is being applied. Symbol intermittently shows up on dash. Then goes away after the car has been turned off and restarted. Brakes squeal bad. Acceleration reduction message then check engine light came on 8/30. Roaring loud noise before the light came on. Put 1 gallon coolant in it and light went off. Now runs and idles high.

Vehicle had large puddle of antifreeze under drivers front of vehicle. Antifreeze reservoir was completely empty upon opening the hood. There is an active drip of antifreeze under the car as displayed by placing a clean piece of cardboard under the vehicle. There were no indicator lights displaying a problem on the dashboard. Upon using an endoscopic camera, there is an active leak at the hose on the radiator. If I had not noticed the active leak, I would have driven the vehicle and overheated the engine with the possibility of seizing the engine. Vehicle is in service currently at Superior Chevrolet. There is a known issue under Special Bulletin N262546590 for the seal at the quick connect inlet on the radiator.

While traveling to the gas station I got notification that my acceleration was being reduced and it was very noticeable. After arriving and pumping gas, I started the car and got 3 additional messages. The car aside my brake assist and ESC needed service, my ABS system was off, and my forward collision system was off. While driving, I noticed that the brakes were still working but acceleration was still being reduced. This is an everyday use car and I have a 6 children who I don’t feel are safe anymore in the car. Not being able to utilize the brakes and the reduced acceleration is very concerning especially when in traffic. I have a little over 27500 miles on the car. It just came from the...

While driving with AWD engaged (winter time only ) , AWD will disengage on its own randomly . Will not allow me to reengage AWD for 24hrs plus, unless battery is disconnected . Dealer has hooked up reader and NO code pops up. Also knocks out lane assist and weather temp gauge .

Wife had car sitting over night from doing a EMS shift. Went out to car in morning to start to return home and when car started ABS light, ECS light, Brake Light, and Collision light came on. This has resulted in no ABS or safety features. Called dealer and can't look at car for over a month. There was no mention about not driving. If the wife needs ABS or front radar, she will not have it resulting in a more serious accident.
