   The car suddenly started bucking while driving on I95 at about 75 miles per hour. We were able to coast off highway and when finally towed to a dealership we were told we needed a new engine. The vehicle at the time had about 57,300 miles. It was very scary to be on a dangerous highway with tractor trailers speeding past and have NO control over the vehicle.

The vehicle had a prior Safety Recall performed regarding this issue, but the engine failed anyway. GM did replace the engine under warranty, but I…

My family and I were trapped on the express lanes for over an hour in a dangerous location. The vehicle stayed stuck in park even on the tow truck.

We had to arrange our own transportation for both us and the vehicle 8 hrs back to our home in Rapid City, SD where our local dealership replaced the engine. The vehicle had approximately 65,000…
