2020 Buick Encore Gx

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 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.

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.
