- Buick Ownership
- Regal 2013
I have a 2013 Buick Regal with eAssist. This occurs at multiple speeds, but the latest event was when driving at around 65 mph on the highway without the cruise control engaged the vehicle door locks suddenly unlock and lock, the car downshifts and the rpms go way up and a light comes on that says "service power steering". I have been taking it to the dealership for the last year for this issue and they say that because there is no code dropped in the computer when it does it and they don't have it happen when they test drive it, they don't know what to do. The car has 80K miles. The issue is occurring more frequently now than when it started. The entire event lasts for about 10 seconds but it is vary scary when you are driving along at 65 mph and all of these these events just happen, especially the high rpms, because it's like engine braking as the transmission downshifts I all of the sudden I am at 58 mph and people behind me are having to dodge me. Is anyone else experiencing this and what was done to resolve.
