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

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.

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.

The contact stated that the failure only occurred while the air condition was activated. The local dealer and the manufacturer were not notified of the failure. The failure mileage was 18,000.

EXTERIOR LIGHTING

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 on without my control, but I am unable to upload them. I brought it to my dealership and they returned the next day saying there is nothing they can do and to bring it in when it occurs next. I live 40 minutes from the dealership and don't really have time to stop what I'm doing when the computer glitches, usually 40% of the time. In addition, I reported it to my dealership and Buick customer care. I was told on January 30th that a supervisor would reach out regarding my case, but I have not heard back.

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.

While driving at a low rate of speed, turning or speed bumps the vehicle starts to rattle in the front end and steering wheel. Engine feels like it slips while rattling from the front. Seems like a motor mount, suspension, tie rod or some other component. Brakes are very hard and make lots of noise. When starting the vehicle on an incline it Lunsford forward out of control.

Malfunction of rear passenger doors and back trunk/hatch. My safety and the passengers of others is significantly at risk, the doors open slightly when turning, the seal of weather stripping opens and sounds of road noise is louder than if the door windows were open. Upon closing the drivers door and a passenger opening the rear driver side door the metal touched and made a loud metal impact sound. Paint has been removed from both doors in the exact same spot that this occurred. It seems as if the doors installed either have a faulty hinge, wrong doors attached on the rear passenger doors or their is a faulty design or weld. The rear door on the driver side is visibly unaligned to the drivers door and it appears the manufacturer added extra weather stripping to compensate for the incorrect door being installed. While the doors are locked and the vehicle turns or travels over bumps in the road it is very noticeable and I do not feel my passengers are safe. I’ve never had a vehicle separate the door from the frame while driving. This can’t be safe.

Vehicle appears not equipped to operate in heat with air conditioning on. Vehicle struggles to keep running, idles high and jerks while driving on the highway. When trying to accelerate after slowing down it doesn’t accelerate.

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.

WHEELS

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 serviced at a local dealership, took it back with said bolt and they did not put it back. To date I’m unaware of where it belongs. Dealership has oil change tech diagnosing, consistently “functioning as normal” and “can’t duplicate issue”. I do not feel safe driving. Hard to stop and feel in control. I’ve resulted in getting rides from others when possible. 2023 GX AWD is not safe. Manufacture notified.

I bought my car, new, on 10/1/ 2023. The middle of November i noticed the headlights randomly dimming. On 12/3/23 I to the dealership to have them looked at. I was told there was nothing wrong but make an appt. they had my car 3 times in less than 2 months. I repeatedly told them my headlights were dimming and or going off. On Jan 13 after taking my daughter to the airport my headlights went off as i was merging on to hiway at 6:30vam. at that point i filed a complaint with GM.. They won't do anything because the dealer said the lights function'. I have not driven my car after dark Jan 113. I am terrified that it will happen again.

SEAT BELTS

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.
