Vehicle struggles to stay running in the heat with the air conditioning running. Low voltage codes pulled at dealership. When the air conditioner is running there is an awful toxic smell from the vents both with or without recycling the air. Vehicle struggles to slow then accelerate, such as normal driving conditions in rush hour traffic. Poor ability to accelerate, hesitant and jolting. AWD model with winter package in the desert doesn’t fair well.

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.

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 l

I was driving and randomly my new 2023 Buick Encore GX and two error messages popped up and my brakes started being less responsive. The two error messages that popped up was "Service ESC" and "Service Power Steering". I will be calling the service department tomorrow to get it checked to make sure nothing is wrong. This is apparently an issue with GM cars but I need to verify that it is not an ongoing issue.

The shifter assembly failed. When shifting to Park, a "Shift to Park" message appears on the driver information center. Although the shift lever is in the Park position, it is not recognized, and the car cannot be turned off or locked. The selling dealership inspected and confirmed the failure, which first appeared at about 21,000 miles (2023 model). The solution was to replace the shifter assembly (car is out of warranty by less than one month), at a cost of $562.10. Invoice breakdown: 1) Labor = 350.00, 2) Parts = 169.50, 3) Sales Tax = 42.60 It is interesting to note that the Labor rate of 350.00 is almost certainly a "flat rate", as the time to complete the repair was only about 30 minutes.

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).

Vehicle chrome trim on the inside dash blinds driver between 12:00 PM - 2:00 PM. The bright chrome is blinding and becomes a safety issue while driving. The design and placement of the chrome is burns my eyes while driving. Perhaps not using chrome on the interior when sending vehicles to places where it is sunny 95% of the time would prevent safety issues with visibility.

What component or system failed or malfunctioned, and is it available for inspection upon request? I reported that my display screen would often appear corrupted when navigating. The screen will either go blank or appear grainy, preventing me from accessing the navigation or music features. Restarting my phone or turning off the display does not help. I missed a turn on a highway with heavy traffic en route to the airport most recently and it is increasingly stressful dealing with it. At another instance, my brights would come on randomly. I turned the lights off and on, which was dangerous, which did not even work. I am concerned that this may happen again, which will put the safety of myself and others at risk. I have a video of the incident where the brights kept going off and

11/14/2022 ODI #11493530.0

Our new 2023 Buick ENCORE GX's brakes continually GRAB whether we are approaching a slowed vehicle in front of us or not. Also, beginning yesterday, the brake pedal that I step on to start the vehicle was totally locked up and I was unable to start the car for awhile. Then, this issue went away and I could start the vehicle. More so, the constant grabbing of the brakes is dangerous. There is no rhyme or reason with this dangerous problem. The Buick dealer in Redlands says they are aware of the touchy brakes but offer no resolve. Can you help us? Thanks

No accident just a concern. On my Buick the clasp for the front set belts are buried between the seat and center console. Making the fastening and unfasting very difficult. The further the seat is forward the more difficult it is. I guess my concern is this over sight may hamper the use of them or possibly cause entrapment during a stressful situation.
