SHIFT INTO PARK WARNING WHEN CAR IS IN PARK
SHIFT INTO PARK WARNING WHEN CAR IS IN PARK
Powder Train When parking the car in garage, placed vehicle in park, then turned vehicle off, received a message on dash "SHIP TO PARK". The car was in park. Even thought the engine was off, it would now allow radio or lights to shut off util message goes off. Some times several minutes for it to go out. Taken it to the GM dealer ship was told shifter assembly needs replaced. I have learned their currently is a a class action suit for this issue at this time. My car was under warranty for 5 years and was still under the warranty when this happened to me. I don't feel I should have to pay $491.00 out of my pocket.
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. M

I am getting a shift to park message on my Buick. I have to shift through heats multiple times to get it to stop.
When I put the car in park and go to turn off the car, I'm getting a "Shift to Park" error when the car is already in park. This error will not allow the car to shut off. I have to shift it back out of gear and then back to park several times before it will recognize that it's in park and allow me to turn off the car.

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.
I was traveling to school when my breaks didn’t work I tried them twice and I crashed into another vehicle. And the month or march I took it into to Buick for break issues and they said everything was fine.
Shifter malfunction not allowing transmission to shift to park without multiple attempts. Car lurches at times while attempting to resolve problem.
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
