2020 Buick Encore Gx

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.

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.

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 "

This is a new issue. Upon exiting my car last night. My car would not shift into park. Everytime I cycled the engine and shift to different gears then park. The car stated it need to be shifted into park still. Without it being in park The car could possibly roll down the hill. Also without it being able to be shifted into park. It continued to flash and keep lights and warning sign on. If not being able to shift into park. I could not leave my car until it recognized the car was in park. The car battery would have drained.
