Severe transmission shudder, issues accelerating. Torque converter failure is very common with this vehicle, even with following routine scheduled maintenance. There is no engine or MIL light on and symptoms appeared out of nowhere. Failing to be able to safely accelerate can cause accidents, putting lives and property at risk. Looking information up online will show that this is a very common issue with this model year and transmission.

The alternator failed randomly while driving down the road. The vehicle only has 26500 miles. There was no lights on prior to the car stalling. When it failed my whole car started to flash every warning at the screen to me. My car then stopped working and I barely was able to coast into a parking lot. Luckily I was not on the highway and no one was behind me when the car stopped working. The problem was confirmed by the dealer it was the alternator. What sucks though is that the alternator killed the battery. The battery is not covered by warranty so it is $507 to replace a battery.

Leaking exhaust noise at start up began around 7/14/25. Noise became louder over the following week. Check engine light came on morning of 7/25. Immediately took it to local GM dealership for inspection. Dealership first said it was a cracked front exhaust pipe but then they also determined that the check engine light was from the catalytic converter. Dealership said both the exhaust pipe and catalytic converter require replacement. Through research, we discovered there are already recalls and special coverage for the same issue on the 2019, 2021 and 2022 year models of this vehicle.
