When trying to park/shut off, the vehicle gives ‘shift to park’ error message upon shifting to park and won’t shut off or when starting will give ‘shift to park’ error message and not start. This seems to be a common issue with this vehicle model…we could really use a recall

Trying to understand why a recall was not done on an engine issue on this car and instead GMC chose to send out 2 letters in 2024 detailing the problem that "might" happen with the engine losing power while driving and for owners to "carry" the letters in the glove compartment of the vehicle so the dealership could be aware of the issue. You were told to not bring the car to be serviced unless the issue was obvious. Well it happened when I was out of state and had to immediately find a GMC dealership to fix the issue for which my car was in a dealership in [XXX] for approximately one month. If the proper recall would have been made I would NOT have driven the car out of state prior to getting it fixed. I had family members in the car with me at the time and to lose power on an interstate was very scary to say the least. I feel that GMC failed it's customers with this vehicle and I will never buy another GMC vehicle or for that another vehicle US made vehicle. The issue was fixed

2021 Buick Encore with 25000 miles. Warning message “SHIFT TO PARK” while vehicle is in park. Dealership says shifter and knob need replaced at an out of pocket cost to me of nearly one thousand dollars. GM has already settled claims for this problem with Chevrolet owners.

When I put my car into Park, a bell alarm sounds and a message shows up to put the car into Park. While it’s already in Park. I then push the stick shift forward and the bell alarms stops and message disappears.

This is an ongoing issue that I have brought to the NHTSA's attention before, which resulted in a special coverage program being issued; however, now GM is not willing to assist me with the special coverage program due to a branded title (used vehicle), and the condition is only getting worse. Tonight, on August 16th, my vehicle experienced a complete loss of power, including engine functionality and fuel/propulsion systems. This stems from the original complaint I filed last fall (11614068) in relation to the turbocharger. I was advised by GM that they would not service my vehicle multiple times by rude supervisors, as my vehicle did not qualify under the special coverage because it's not a "safety issue:", and that the NHTSA has not issued a safety recall for this issue, when it's a safety issue. This is outrageous, and I URGE the NHTSA to look into the severity of this issue. It's only a matter of time before I am on the highway when my vehicle experiences what it did tonight. A com

Once a day sometimes twice, when I have pulled into a parking spot and put the car into Park, a bell alarm sounds and a message shows up to put the car into Park. Since I already put it into Park I then jiggle the stick shift lightly and the bell alarms stops and message disappears. This started within last 6 months.

About 6 times in the last 3 months when I put the car into reverse and the reverse camera comes on the image is kind of sketchy and in weird colors - definitely not clear then it completely goes black with message at the top saying something about getting the rear camera repaired. It doesn't happen often but I can't use the rear camera when it does that so it's back to old school when in reverse looking everywhere and in mirrors before moving. It hasn't happened but once so far this month July 2025 but thought you should know.

Car is put on Park and a warning light comes out saying car is not on park.

Turbo charger has gone out 4 times since I purchased it in April 2021. I have been on the interstate driving and suddenly my car slows down and a message that says “engine power reduced” comes up and my check engine light comes on. This is dangerous as I was on the interstate with 18 wheelers and could’ve been rear ended and badly hurt or killed. My grandchildren could’ve been in the car with me. When this happens the vehicle slows down considerably and does not accelerate properly. I have to drive in the right lane at a much slower speed putting myself and others in danger. Leachman Buick in Bowling Green, KY has repaired the car twice. Campbell Chevrolet in the same city has repaired it twice and it is currently at this dealership due to the engine power situation occurring again. This has caused me severe inconvenience as I have had to drop my car at the dealership several times in the past few weeks and rearrange my schedule as a rental car has not been provided. Campbell C
