While driving my 2020 Buick Encore GX, the vehicle experienced a sudden and dangerous loss of acceleration, immediately dropping into 'Reduced Engine power' limp mode in active traffic, but no other car was Infront or behind my car. A diagnostic scan revealed Diagnostic Trouble Code (DTC) P2138, which triggered the computer's safety override system to cut engine throttle. The official dealer repair invoice confirms a manufacturing and assembly defect covered under GM Technical Service Bulletin (TSB) #07-06-04-019G. The technician located water intrusion Panel/Body Harness Connector X112. The root cause was an improperly seated weather seal from the factory, which allowed moisture to short-circuit the accelerator pedal sensor voltage lines. The shop had to reposition the factory seal and apply dielectric grease to the terminals to correct the defect, for which I was charged out of pocket. This manufacturing defect caused a sudden, unpredictable loss of vehicle power on public roads, creating a severe rear-end collision hazard.

There was no service engine warning light on my dashboard. Pending codes in the pictures below popped up on my diagnostics tool less than 24 hours after buying the vehicle from an Audi Dealer. The engine went into limp mode as you can see from the picture below that shows Engine Power is Reduced. After researching these error codes, I was made aware that this is a common issue on this vehicle ad is should be a recall as it states the engine failure is a very serious issue, especially if it occurs while driving. This could cause fatal accidents.

While reversing, the vehicle suddenly jumped/jerked unexpectedly. Another vehicle was parked close behind me, and I was afraid my vehicle was going to jump into it because the movement was sudden and difficult to control. On another occasion, while traveling approximately 20 mph through a longer curve, the vehicle suddenly jumped/jerked again and I was concerned I could lose control of the vehicle or strike another vehicle. The vehicle has also intermittently shuddered/jumped during normal driving and acceleration. At times the engine RPM increases without the vehicle accelerating normally. The problem is intermittent and may stop and then happen again. This makes the vehicle’s acceleration and movement unpredictable, which I believe creates a collision risk when reversing, entering traffic, traveling through curves, or accelerating around other vehicles. An authorized Buick/GM dealership inspected the vehicle and diagnosed the CVT transmission as needing replacement at a cost of approximately $4,700. The dealership told me there were no transmission diagnostic trouble codes and no transmission warning lights despite the symptoms and their diagnosis. I am concerned that this transmission condition can cause sudden jerking/jumping and unreliable acceleration without a warning light or diagnostic code alerting the driver. The transmission has not been replaced and the vehicle is available for inspection.

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.

My 2020 Buick Encore GX which has only $30,600 had the "Shift to Park" message appear on the dashboard screen and my car was not turning off properly. I read online that it is a widespread known issue: however, I had to pay $630.14 to fix the GM well know widespread issue so I can turn off my vehicle. This should be covered FREE of charge by GM as they are aware of the issue affecting the 2020 Buick Encore GX.

I am writing to formally report a serious mechanical failure involving my vehicle and to request further review and assistance. While operating my vehicle, it unexpectedly stalled in the middle of an intersection, creating a significant safety hazard. At the time of the incident, the check engine light illuminated and the RPMs surged to a range between 6 and 8. I was able to safely move the vehicle to the side of the road, place it in park, and have it towed to a dealership for inspection. Following their evaluation, I was informed that the transmission requires replacement. I have since become aware of a recall related to transmission issues; however, I was advised by a Buick representative that my VIN is not included in the recall. Given that my vehicle is experiencing the same or a substantially similar failure, this determination raises concerns and warrants further review. I have consistently adhered to all recommended maintenance schedules and have taken proper care of my vehicle. Based on the circumstances, I respectfully request a thorough reassessment of my case, including reconsideration for coverage or assistance with the necessary repairs. I appreciate your prompt attention to this matter and look forward to your response.

My 2020 Buick Encore GX is showing a message with accompanying ding ding sounds "Shift to Park" after I put my car in park. This malfunction will not allow the car to be locked. I see there are many complaints and lawsuits that GM has not attended to. How do we get GM to initiate a recall on something they are and were well aware of.

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)

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. This malfunction can lead to battery drain, failure of a vehicle to shut off completely, or difficulty starting it.

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 "

I was at a stop light and the light turned green, I preceded to press the accelerator, I was just starting to move forward and the, peddle seemed to take over with my assistance went all the way down and began speeding up. I tried breaking and the car just kept going and not wanting to slow down and kept gaining speed, I had to put car in neutral and turn engine off. Same day, same trip about 4 miles down the road, I began to slow down (35mph) due to a turning vehicle and when I was clear to accelerate once again, it happened again, again, I tried the breaks, and the car kept fighting the break and kept gaining speed, once again I had to put the car in neutral and turn off the engine, the speeds reached 65 mph. before I was able to place in neutral and turn off the engine. No warning lights, car ran normally until those terrifying moments, no check engine lights on before or after the above experiences. My husband and I's safety was put at risk due to the road's travelers and Deadmans curves and cross sections, it put us at risk with a higher chance of crashing into a vehicle or accelerating before being able to make a turn safely. As soon as I made it home, I called the Buick service center and delivered the car the following morning to the service technician. It is at the Ross Downing Service Station today.
