Vehicle suddenly stopped accelerating over 20 mph and became unable to reverse. This was discovered while driving. We do not have the funds to make this repair. The car has sat at the end of our driveway in a non-drivable condition since April 2019. The rear strut towers required complete replacement. This was noticed while driving 10 mph. The car made a clunking noise. I took it to the Buick garage and they recommended the strut towers be replaced and the rear axle. They have record of the date and mileage. The power steering cable rubbed on the air conditioning line and a a hole was created. The air conditioner became non-functional. A diagnostic was performed by the Buick garage but, we did not have the funds to repair the air conditioner since we needed to rebuild the strut towers. So we drove the car with a non-functioning air conditioning unit, until the car stopped operating in reverse and stopped accelerating over 20 mph. I am a single mom with 3 children. This has been a great hardship for us. It is very unlikely that I would purchase a car from Buick in the future.
