2004 Chevrolet Impala SS Supercharged 4dr Sedan (3.8L 6cyl S/C 4A)
We loved the car overall until the last year. It was a lease car. Most of the time when we got the car up to 50mph the car began to shake and lunge and lurch like it was hurting for gas. We took the car into several car dealers to fix it and they thought we were crazy. We did find one dealer that could see it, but was never able to get it to do it at the right time for the computer to tell there what to fix. Well, after the lease we were sad to give it up, but some poor person probably has it now.
dealers need to start listening the the owners that are driving the car on a regular basis to fix problems.
