2020 Chevrolet Traverse

I recently had to replace my transmission (2020 Chevrolet Traverse) due to shuddering from manufacturer's fault in assembly process. Now I'm having to replace the transmission in my mother's 2018 Chevrolet Colorado that has less than 65k miles. These issues cause power loss while driving. I was in the middle of passing another vehicle when my vehicle experienced power loss. This is a HUGE safety issue, not only for my family but many others that I know that are experiencing or have experienced the same issues. I have 3 family members that have had to have the same repairs as well as over 40 acquaintances. I had assumed with the thousands others that I've chatted with on facebook and reddit that this would have been a recall, sadly, GM/Chevrolet doesn't seem to care that it is their fault that their consumers are having to spend THOUSANDS of dollars to correct an issue that leaves the manufacturer at fault. With the thounsands experiencing the same issue, i feel that those that have already had to spend money should be reimbursed.

I am sure this was an issue to begin with.

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.

The contact owns a 2020 Chevrolet Traverse. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate while depressing the accelerator pedal. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who retrieved diagnostic trouble code: P0091 (Fuel Pressure Regulator 1 Control Circuit Low). The contact was informed that the high-pressure fuel pump needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.

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.
