Engine Belts And Pulleys problems of the 2011 Buick Regal

Driving my car at around 30mph, the car completely shuts off without warning. There is no shutter or sound. It is just suddenly completely turned off. No brakes. No power steering. No gas. You must pull the car over. Come to a complete stop. Put the car in park. Turn the key completely off, and then the car will restart almost every time. This has happened to me 5 times in the 9 years that I have owned it. But it has happened 3 times in the last 3 days. No mechanic nor the dealer can identify the problem. I have replaced the serpentine belt twice, and the throttle body/throttle position sensor.

Our cur completely shut off all power lights engine everything doing 80 mph on interstate 84 in idaho. A semi seen it happen jumped in the middle of both lanes to block traffic so we could get to the shoulder. In a no cell phone area 13� we disconnected the battery and had to shift srive it in limp mode. No alert lights came on we took it yo a certified dealer to find the pistons, timing chain and other things are ntoken gm/ Buick was notified they decided to decline assistance because we are out of warranty 93k miles on the car and over 5,000$ in repair and possibly another 2100$ to repair the cadilitic converter. We were in a no cell service area and had to drive in the shoulder now the headlights won't turn on at all either. The car never alert us it just shut off the dealer says the oil was very low again no oil light came on with that yhe dealer says therecould be a bcm/ecm communication issue costing 1200. 00 to 2500. 00 to fix. They can't assess completely until the piston/ timing belt issue is fixed but the car is not communicating the steering is now super tight and the only yhing it says now is service stibilatrac and the mechanic didn't even bring that up.

I have had to turn my vehicle into the shop on multiple occasions regarding my vehicle breaking down in the middle of traffic, the card basically runs like a toy! within months of purchasing this precertified one owner vehicle, the oil light supposedly was recalled and did not function-car had absolutely no oil. I continued to received Buick handled maintenance and still experiencing issues. The vehicle still looses oil within range of not needing a change. The card jerks and when approaching stops and will completely cut off. I recently got my car back after two weeks of repairs replacing of engine pistons, belts so on and so forth however today after coming to a stop at a stop light, the car began to jerk and shake and the died. The light turn green and I was in front of a school bus! I cannot be on the road and my car cutting off in traffic after multiple repairs! this was my first car purchase and I am more than disappointed. Once again I have to take my car in to see why the issue continues.

I received a letter from Buick which said my balancing belt (timing chain) could break causing engine damage. They would not do anything about it until it broke. They extended the warranty in case that happened. If the timing chain breaks and the engine stops, I will lose steering control which is a comforting thought. If I am on interstate doing 70 mph and lose steering, good bye!.

While travelling 55 miles per hour on the high way the car shut off causing me to force the wheel on the road. I reported this and was given rental cars for the noises and belts to be examined. The noise subsided a few weeks only to return when driving about 45 miles per hour and the car cut off again. This time in traffic March 2013. The thrid time was in April 2013 . The last time was June 16, 2013. It has been in the shop over 45 days. Nothing was told to me was wrong. Then why is it shutting off while im driving?.
