Top problems in owners’ words
Verbatim from NHTSA complaints, newest first
Engine
6 reports
“Engine power reduced all of a sudden on a highway. Turbo went out at less than 45k miles. Turbo was replaced by GM and was told this will occur every 2 years by the dealership. Very unsafe especially driving at highway speeds.”
Steering
5 reports
“Stabiltrack software jerking my car in a left curve. Took to dealership who seem to find nothing wrong. Reached out to GM with no response or action. Feels extremely dangerous in a left curve unless traction control and Stabilitrack is turned off.”
Electrical system
5 reports
“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.”
Service brakes
5 reports
“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. Clunking noise when turning left at a low rate of speed with minimal acceleration, such as in and out of a driveway, parking lot or after coming to a stop at an intersection. Mostly heard only turn left. Steering wheel vibrates at high rate of speed. Intermittent rattling noise heard from front center/passenger side. Ratting noise occurs after driving a while 25-30 minutes. Screw fell out of vehicle after being…”
Fuel/propulsion system
4 reports
“Engine light. Codes, P146B, P0114, C2B00 @ 64000 miles and the emission purge pump has failed, ECU, purge solenoid. I see an extended warranty has gone out for the same year Envision. As this is the same P/N for this brand and same problems, (I.E. 2020-2022 Encore extended warranty) will this be covered anytime in the future?”
Power train
3 reports
“When starting from a traffic light after the green light, the car made mechanical noises and would not accelerate above approximately 25 mph. It seemed obvious at the time that the transmission had failed, which was later confirmed after being towed to the dealership. There were no warning lamps or messages displayed; however, during the previous days, there were a few instances when the transmission "shifted" hard (this seemed odd considering it is a CVT transmission).”
