Brakes are noisy more going in reverse. Dealer ordered updated front brakes on 12/8/2020 and as of 12/23/2020 they have not been received and do not have a date when they will be in. Tried to call gm customer service but they do not answer the phone. Also when the car was in the repair shop they completed recalls #'s a202310450, a202295530 & a202301230. Also I never received any notices on any recalls from Buick.

Dealership, fixed brakes due to previous recall. Brakes continue to squeal and grind with every stop. Was informed by dealership that they can do no further repair because it is considered a noise and not a safety issue. Grinding brakes are a safety issue!!!

For the past several months, my 2020 Buick Encore has been giving me a message to shift to park even though I placed my vehicle to park. This then does not allow my car to shut off, because it believes I am still in drive. I tried making an appointment with the dealership a month ago and their earliest availability was today, 12/10/2024. I took my Buick in, and they wrote me and stated that they figured out the issue and the shifter control would need to be replaced and was not covered under my powertrain warranty. I see this has been an issue on several Buicks and I even found the service notification Buick sent out for this specific issue. This is a definite safety issue since I cannot turn my vehicle off because it does not believe I am actually in park. This needs to be recalled for th

While driving up to an intersection I applied my foot to the brake pedal. Upon doing so the pedal did not move as if it was locked in place. I applied more pressure as I was coming up to the intersection and then the steering wheel locked in place as if the car was off. The brake pedal went completely to the floor with no brakes being applied. I quickly began pumping the brakes which started to slow me down but not before driving right through the intersection. I pulled over after I was able to slow the car down to a stop, turned off the vehicle, waited a few minutes, and turned it back on. I was able to return home but immediately called the dealership.

My vehicle is undrivable. Multiple times per trip the check engine light comes on and I see multiple messages come on the driver information center. These are: Service ESC Reduced Power Service Adaptive Steering System The codes that come up are: P0089 for low fuel pressure P00C6 This results in an immediate speed reduction nearly causing multiple collisions with people following me on the highway. As a result I have been using a code reader to clear the codes so i can continue driving. I refuse to drive on busy highways so I am always forced to drive back roads. This needs to be figured out ASAP!

To Whom It May Concern, I am submitting a formal complaint regarding a recurring issue with my 2020 Buick Encore GX (VIN: [XXX] ) related to the “Shift to Park” defect, which is documented in GM’s Technical Service Bulletin 23-NA-119. My vehicle intermittently fails to recognize when it is in park, preventing me from turning off the engine and causing safety and usability concerns. Despite following GM’s recommended steps and scheduling an appointment through Buick Customer Care, I was charged $195 for a diagnostic fee and quoted $495 to replace the shifter assembly. The dealership confirmed the issue matched the bulletin, yet refused to offer goodwill coverage or reimbursement. This expense is a significant hardship. I am still making payments on this vehicle, which is barely five year
