2022 Chevrolet Trailblazer

I was driving down the highway when the 3 bolts holding the exhaust under the car broke off. My exhaust was dragging down the highway until I could safely get pulled over. The bolts are welded in of course so you can’t just put new bolts in you have to replace the whole catalytic converter, which is a pain to do unless you take it to the dealer and pay $2000.

The car showed an error message saying shift to park when trying to turn the car off. The car was in park and showed in park on the dashboard & shifter but the error message still said it wasn’t in park. While this error is showing it will not allow the car to shut off or lock doors. I have a little over 19k miles on this car and should not have this issue. After researching this has been a know issue with their vehicles for years and it still has not been addressed.

I am having issues with putting car in park. Keeps showing not in park and will not shut off until I yank on handle. Getting worse & taking so long. Took to dealership and they said probably the harness and would cost $400 to $600 to fix. My research shows they have had this issue since 2018!! Only recall I could find was in Ohio. I feel angry they still keep using a defective part and expect us to pay to fix. I am older and on fixed income & don't have the money. Also why should I when it's their ongoing issue. I'm scared of this not letting me shut off car till I run out of gas!!

Vehicle experiences intermittent loss of acceleration at highway speeds. While driving at highway speed or going uphill, up ramp, down hill, down ramp the engine loses power and enters reduce power mode, making it difficult or impossible to maintain speed or safely merge with traffic. The issue is unpredictable and has occurred despite prior repair attempts. Vehicle is covered under a GM special turbo warranty for a known defect. Warranty came out Oct 2022, Due to the loss of power the vehicle is unsafe to operate and is currently at the dealer.

The cruise control system intermittently fails to engage indicating an error with the system. After several random occasions it was finally determined that the issue is related to the brake pedal sensor not determining that the brake pedal has been fully released. It requires having to manually pull the brake pedal up to properly set the sensor to allow the cruise control system to engage. This does not present any clear danger in itself, however, after having the vehicle inspected the manufacturer service center states that the entire pedal assembly has to be replaced because of worn parts and that the pedal may continue to get worse. While the mileage has taken the vehicle out of warranty that covers this issue the car is primarily driven on the interstate with minimal wear and tear on the pedal assembly.
