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. …

I had stopped at store on way home from work. When I came out of store I noticed smoke coming from under the hood of my car. I popped the hood and saw my engine on fire and proceeded to try and put the fire out. I took my jacket off and started hitting the engine and this burned up my jacket and scorched my hand. An employee from the store came out with a fire extinguisher and put out the fire. The fire department was called but fire was out before they got there. It burned up the entire top and sides of my engine. Their was a recall that would have stopped this but I did not receive it.

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.

On or around October 2013, I started experiencing difficulty in turn ignition switch off and removing key. Now its worsen where I spend anywhere 5 mins. To 15 min trying to remove the key. Only way I can do that is by turning the steering wheel or moving the gear selector back an forth till it decides it release the key.I thought it might have been the anti-theft in column that was locking up. I'm scheduled to have a new ignition installed after replacing the old key with a new key. I like to make sure this is covered before I sink anymore money into it. I depend on the car to make to doctor appointments and suck I often am late for because I"m in the parking lot playing spin the wheel. The other factor is steering wheel get extremely hot when driving at times. Where I have to put on gloves to drive. …
