  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!

  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 these vehicles since Buick is aware of the issue. I am getting the shifter control replaced, but due to it being a safety concern, it should be covered by Buick. Instead, this is being told to me that it is a $400 replacement part and not covered under Buick's warranty. I wanted to file a complaint so NHTSA can be aware of this issue.

  The dash shows an error message "Shift to park" whenever I put the car in park. This message last for about 10 minutes or more locking me in the car.

• 10/25/2025· UNKNOWN OR OTHER,BACK OVER PREVENTION

  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 years old. I previously owned a Honda for 20 years without encountering issues like this. Unfortunately, this is not the first time I’ve faced a manufacturer-documented defect with no support. My previous vehicle, a Mitsubishi Outlander, suffered from a known transmission issue that was later part of a class action lawsuit. Despite experiencing the same symptoms, my VIN was excluded. The cost of repair outweighed the value of the vehicle, and I ultimately had to walk away from it as a total loss—leaving me without a car. I am deeply disappointed to now face a similar situation with Buick. I chose this vehicle expecting reliability and support, and I’ve done everything asked of me to address this issue responsibly. I believe GM should be held accountable for this known defect and the financial burden it places on consumers. Thank you for your attention to this matter. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

• 07/22/2026· ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM

  I am submitting this complaint regarding several serious mechanical and electrical issues with my 2020 Buick Encore GX that raise significant concerns about the vehicle's reliability and safety. Most concerning, I was recently informed by the dealership that my vehicle requires another transmission replacement, despite having the transmission replaced in 2024. I was also advised that I would need to pay for an additional diagnostic inspection because technicians discovered oil leaking through the lines, which appears to have contaminated engine components. According to the dealership, metal particles have been found within the engine, causing it to malfunction. They have stated that they are unable to determine the source of the contamination at this time. In addition to these major mechanical concerns, I am experiencing several electrical and system malfunctions, including: The passive keyless entry system does not consistently unlock the doors using the exterior door handle, even with a brand-new battery installed in the key fob. The vehicle repeatedly displays a "Shift to Park" warning even though the gear selector is already in the Park position. The vehicle continues to display brake-related alerts and notifications indicating that the brakes need to be serviced or replaced, despite having brand-new brakes installed. These ongoing issues have resulted in repeated repair costs, loss of confidence in the vehicle, and concerns about my safety while driving. The transmission failure occurring shortly after a previous replacement, combined with unexplained engine contamination and persistent electronic malfunctions, suggests there may be underlying defects that warrant further investigation. I respectfully request that these issues be thoroughly investigated to determine whether they are related to known manufacturing defects or warrant a safety recall or other corrective action. I also request that Buick review my repair history and provide appropriate assistance.

I called the Buick GMC dealership where I purchased the vehicle and they said to bring it in. They pulled codes on it and it gave a code of "engine under boost" and they said they ran tests on it and could not find anything wrong after 3 days at the shop, they did a software update and told me to come and pick it up. Then not even a week later, I was driving and out of nowhere came the same engine light, message read "engine power reduced" and the engine lost power immediately and I called the Buick GMC dealership again and they said to bring it back in and it's there now. I called today to check in and they said they are going to test the Turbo on it and order parts, etc. but they still do not have a definitive answer as to what's wrong with it yet.

  I have started to receive multiple 'Shift to Park' messages when attempting to turn off my vehicle after already being placed in park. To get the car to register that it is indeed in park, I have to re-shift or slam the gear shift into place. I was advised that the issue was with the shifter assembly which prevents the vehicle from recognizing whether or not it is in gear. I had no issues with the vehicle prior to the message and I get my vehicle serviced regularly.

  I have only had the vehicle for a year. On multiple occasions the vehicle feels like it is slipping gears (more often when the autostop feature is turned on). On multiple occasions the vehicle has stalled out and would not do anything when pressing on gas- didn't even rev, did absolutely nothing. These stall outs happened crossing highways, at stop lights, stop signs, etc. There were no warnings prior to the incidences, though the vehicle did through an engine/transmission code afterwards, the code would go away. The first several attempts of taking it to the dealership (last year) as it is still under warranty- it was not checked. i was simply told it was a "glitch" and it was fine. They did not record in their system that i requested it to be checked either apparently. They only recorded that i brought it in for an oil change. They only checked into it this February after my boyfriend told them what it was doing. They kept it and replaced one part in the transmission. The vehicle continued to have the same issues and threw a code withing the first 5 minutes after picking it up. I took it back in- and they said it was doing the issues because of the code it threw. I told them it was doing it again before it threw the code. They said it simply needed a line vacuumed out, and then gave it back to me. It continued to have the same issues and stalled out again causing me to roll backwards onto the highway-into traffic. I took it back again. They kept it, and then told me they'd be replacing the entire transmission, but it is on backorder. Still no time frame when it will be repaired. They then told me i could have my car back and continue to drive it until the transmission comes in?!? I said no- it isn't safe, I just told you what happened and i could have been hurt or killed. I am not driving it, especially when i have my son to drive around as well! I have been without my car for at least a month now. I am paying for a car that i don't even have/can't drive.

This should be covered FREE of charge by GM as they are aware of the issue affecting the 2020 Buick Encore GX.

• 04/13/2021· UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE

  THE VEHICLE HAS A SOFTWARE ANAMOLY ACCORDING THE THE DEALER THAT HAS MY SES LIGHT ON AND MY PRE-COLLISION ALTERS SEEM TO NOT BE WORKING SINCE THIS OCCURRED. THE SES LIGHT CAME ON 4/9/21 AND WAS TAKEN TO THE DEALER. I PICKED THE VEHICLE UP ABOUT 6 PM 4/12/21 AND THE LIGHT WAS ON STILL AND NOTICED IMMEDIATELY THAT THE PRE-COLLISION WARNING DID NOT WORK WHEN ANOTHER VEHICLE CUT ME OFF AND STOPPED SHORT IN FRONT OF ME. I DO NOT FEEL SAFE DRIVING THE VEHICLE. BUICK WAS SUPPOSED TO HAVE ANOTHER DEALER CONTACT ME TO GET A SECOND OPINION BUT AS OF THIS THEY HAVE NOT CONTACTED ME. THEY EXPECT MT TO DRIVE THE VEHICLE AND IGNORE THE LIGHT SO IF SOMETHING DOES HAPPEN I WILL HAVE NO WAY OF KNOWING BECAUSE THE LIGHT IS JUST ALWAYS ON. IF GM CANNOT KEEP UP WITH SOFTWARE UPDATES TO KEEP THEIR CUSTOMERS SAFE PERHAPS THEY SHOULD NO LONGER BE IN THE AUTOMOTIVE BUSINESS.

  While driving this 2020 Buick Encore GX with around 7,000 miles on the odometer, the entire electrical/electronic system shut down. Windows were inoperative, the AC stopped, the radio failed, the flashers did not work, etc. The only things that worked were the engine and brakes. I have no idea if the brake lights worked. I was able to drive the car to the dealership - Van Buick GMC in Scottsdale, Arizona where the car is now sitting and awaiting their inspection. In the 95 degree temperature here in AZ, I thought that I would die as I could not open the doors. I have since learned that I could have opened the doors by pulling the door handle twice. No one ever educated me on this. There were no advance warnings prior to the failure. This car is a death trap. Please NHTSA help me.

  The gear shift when placed in park and the car ignition turned off would cause an alarm to go off and a message to show up on the dash that the gear shift should be placed in parks (which it was in already). When I contacted the GM in CA dealer and talked to him he advised me it was a common problem and the was a shortage of parts to repair but bring it in because the alarm would where down the battery. After jamming the gear shift in park many times I was able to stop the alarm. Them I drove from CA to NV to the Buick dealer there and told me the same thing that the GM dealer tome about a shortage of parts because of this being a common problem and that he would try and get GM to pay for repairs. When I picked up the car I was advised that although this was a common problem GM was not going to be a recall so I had to pay the $558.40 to repair the gear shift. The recipt shows: "SHIFT CONTROL ASSEMBLY REPLACEMENT - found intermittent failure to register shifter position of park - Need to replace shifter assembly "
