What owners wrote
We where ran into on driver side no airbag came out we have had lots of steering problems. As of today there is still problems with the steering wheel engine light stays on and we just wont drive on highway at all.
2004 impala w/ 3.8l engine stalls when decelerating, leaving the car very difficult and un-safe to drive. Currently, the engine starts right back up, but it takes my eyes off the road to put the car in neutral and re-start. I have tried a few inexpensive things such as premium gas, fuel injector cleaner, and a new fuel filter...no affect on the problem. There is no "engine light" which appears. I have owned this car since new and taken very good care of it.
