These stats are promptly updated four times a year, to much more closely track Chevrolet Impala reliability as the cars age.

Rock solid, roomy, reliable. Chevy knows how to build a car. Affordable for a family on a budget, great gas mileage. This is teh 2nd Impala we have owned, and almost certainly there will be a third.

2008 4dr Sedan 211-horsepower 3.5L V6
4-speed automatic FWD
Had to replace wiper motor and body computer module in less than 2 years with no aid from dealer or Chevrolet. $1150 that could have been caused by using the windshield wipers in the winter time. De
2008 4dr Sedan 211-horsepower 3.5L V6

Electrical component failures caused by poor body assembly and sealing. GM will not warranty BCM or under hood fuse panel that failed by "environmental conditions" (snow & Ice & rain) Poor engineering.

4-speed automatic FWD
Thus far, have had problems with the gas cap (the P0455 fault), the speakers rattle, two of the four power door locks have failed, and the gas gauge has gone on the fritz.

We had a lot of little repairs. In 120K miles, 3 water pumps, power steering pump, cracked front cover, alternator, instrument cluster (speedometer, etc..), roof liner started sagging, A/C required a lot of maintenance, int trim coming off and much more.
2004 4dr Sedan 200-horsepower 3.8L V6

Engine oil leaking into the coolant, required major overhaul of engine.
2002 4dr Sedan 200-horsepower 3.8L V6
4-speed automatic FWD
I had the front rotors warp every 3 to 6 months. I had to replace them at my cost as GM would not warranty them. The rear have now warped too. Both front wheel bearings had to be replaced as well as the tie rod ends. All within 70,000 miles. Very poor.
