2021 BUICK ENCORE Complaints

Evap leak detection pump failed at 78,871 miles. 2022 models and beyond are covered for this defect.

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.

The contact owns a 2021 Buick Encore. The contact stated that while driving at an undisclosed speed, the brake pedal was firm while depressed. The contact had to slam on the brake pedal to stop the vehicle. The contact stated that the Hill Assist message was displayed. The brake pedal was pumped several times before the brake pedal released. The vehicle was taken to an independent mechanic, who determined that the brake sensor needed to be replaced. The dealer and another dealer, Mangino Chevrolet, INC. (4447 NY-30, Amsterdam, NY 12010); were made aware of the failure, but informed the contact that there was no recall associated with the VIN. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V588000 (Service Brakes); however, the VIN was not included in the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 38,000.

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 complete loss of power, engine functionality, and the fuel/propulsion systems. I already had a near-death experience while driving on the highway when my engine power was reduced, which caused me to go from 65MPH to 40MPH in seconds on a highway, in the left lane, and I almost got rear-ended by someone going 75MPH. This is a safety issue, and it's not just impacting me. I find it so misleading that GM sent me a legal letter stating they knew there was an issue with the turbocharger and that they would take care of the repairs at no cost to me. The first line on the legal document states, ' Your satisfaction with our product is important to us," unless your car is used and has a branded title. There is nothing on that special coverage notice that explicitly states your title must be clean. I urge the NHTSA to issue a safety recall on the turbocharger so other Americans like me don't have to spend months going back and forth to get a simple repair done, an essential safety repair.

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.

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.

Took to the dealership. They stated my flex pipe had melted and the o2 sensors are stuck in the pipe need replacement as well. They have to replace flex pipe and everything leading to the 2nd o2 sensor. They stated there was no damage or tampering to the flex pipe. This should not have happened in this new of a vehicle. This is a dangerous and costly repair that falls on a faulty flex pipe and not covered by the warranty.

The contact owns a 2021 Buick Encore GX. The contact stated that after parking the vehicle and shifting to park(P), the vehicle failed to immediately shut off. During the failure the message "Shift to Park" was displayed. The contact stated that the failure was intermittent. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 57,000.

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 Chevrolet repaired the vehicle a few weeks ago and the check engine light and reduce power message was back on within 6 hours of them initially completing the repair. Two weeks or less it was the waste gate actuator solenoid that was replaced but the engine message and check engine light are back on. I am VERY FRUSTRATED at having to jump through hoops regarding this vehicle. I own the Bluegrass Edition model and it is obvious that something serious is wrong with the car and Buick needs to recall the car IMMEDIATELY. It is either a lemon or something else is causing the turbo charger to repeatedly fail. I have taken the car to TWO different dealerships and neither one of them have been able to rectify the issue long term. The vehicle needs to have a TOTAL diagnostic test on EVERYTHING relating to the engine and power system. PLEASE LOOK INTO HAVING THIS VEHICLE RECALLED AS I DO NOT WANT TO LOSE MY LIFE ON THE INTERSTATE DUE TO REDUCED ENGINE POWER AND MY CAR AUTOMATICALLY SLOWING DOWN!!

Vehicle overheating randomly due to faulty Coolant Control Valve. Vehicle goes into reduced power mode and also instructs you to pull over and idle engine. Part is on National backorder for weeks. The issue could cause Vehicle to become inoperable and cause a crash.
