Electrical system all 42 →
After driving about ten minutes into my trip last night at about 60 MPH, my Buick Regal 2000 ended up losing the ability to accelerate. It then lost all power and left me stranded on the interstate. I lost the power steering, the instrument panel started flickering. This occurred in a work zone at about midnight. Within five minutes the flashers and lights also went totally dead. Even the trunk would not respond to my remote. The car lights and engine had been very strong and never gave any reason for concern. The key has been difficult to remove from the ignition cylinder for several years. This has been the only source of trouble with the car. The red security light on the instrument panel was illuminated - which is unusual - until the lights quit working. Could this have been a problem with the security system? We have not altered the factory security system. It is original. …
Tl* the contact owns a 2000 Buick Regal. While driving at an unknown speed, the vehicle began to independently reduce speed without warning. The contact pulled over and shut off the vehicle, but it failed to restart. The contact stated that the front of the vehicle began to smoke and caught on fire. The fire department extinguished the fire. A police report was filed and there were no injuries. The vehicle was towed to the contact's residence, but was not diagnosed or repaired.

Steering all 30 →
While driving 20 MPH the steering failed. As a result, the vehicle crashed into a snow bank. The consumer experienced two crashes due to the brakes and the steering locking. The consumer had taken the vehicle to the dealer on three occasions for the steering problem but the locking continued. The dash lights would come on (gas gauge and oil light), the vehicle pulled to the right and the trunk would fly open while the vehicle was in motion.
I was driving my 2000 Buick Regal coming back from work, as I was driving and about ready to go into a steep turn, my stereo system first completely shut off, then everything else in my car failed as well, engine, power steering, etc. I was barely able to get it to the side of the road and when I tried to restart it, it barely turned over. Clearly there is an electrical problem in these vehicles and my car hasn't even reached 100,000 miles even.
