Buick Electra Engine problems by year

Vehicle 2009 buick enclave. Keeps turning on the light engine and at the dealership they keep telling me that is because I don't close the gas knob correctly. When the engine light turns on while im driving it gives me a message of power engine reduce and it reduce my speed and I can't continue driving. I've almost cause 2 accidents while im driving due to this issue. It will completely stop in certain times while im driving. Last incident 06/05/10. As well, my tire got flat around a month ago and I realized the dealership sold me the vehicle with no extra tire and emergency equipment to change my tire. *Tr

Consumer bought a vehicle that was suppose to be in perfect condition. While driving home vehicle stalled and would not restart. Dealer was notified, but informed the consumer to pay for a diagnostic test and the repairs.*Ak

The crank sensor-which controls engine timing-the bracket its housed in can work loose during normal driving causing the sensor to move away from the magnet causing the engine to stall w/no warning. It happened first laste year in july-99 had it replaced by dealer using oe part. Worked loose this year oct-00, causing vehicle to stall on busy street and barely made it to the side. Contact dealer-would not replace part-made us buy another....

Timing chain broke, resulting in steering ability lost, replaced timing belt. Ttwhile at a stop light, engine shut down and failed to restart, vehicle was towed to dealer and consumer was advised that this was a common problem, consumer contacted manufacturer and was told there is no defect in the part.*Jb
