Brakes
Brakes squeaking, squealing and screeching. Replaced once at approximately 8k miles. Dealership ground down rotors twice, brakes replaced once. Tires are worn in the center. AWD GX, steering seems off and unstable. Brake pedal sounds and feels like a faulty spring inside. Pedal gets stuck when switching from gas to brake. Bounces back with spring feel and noise. At times it feels like I can't control the brake when traveling at a low rated of speed and having to suddenly stop. Then while stopped on an incline the brake feels as if it releases while still depressing the brake jolting forward. Nearly forcing into intersection. Having to leave larger distances between vehicles in front to prevent vehicle from forcibly trying to rear end another vehicle. …
I am reporting a serious safety issue with my 2023 Buick Encore GX that repeatedly shuts off while driving and doesn't restart when auto stop is on, it leaves me stranded in traffic. The vehicle has been in the shop multiple times since February 13, and the issue has not been resolved. A service advisor has stated he is not comfortable putting me back in the vehicle and wants to help get me out of this car. I am requesting escalation, a case number, and immediate resolution. After having the oil changed in February, the check engine light came on soon after. Car had left me stranded prior to the battery being replaced. After 4 times in the same shop, they say a bad ground connection may now be the problem, however they also said they recharged the battery the visit prior.
Electrical system
