The light switch, part number 10283776, on my car developed an electrical short circuit and burned out the push-on electrical connector for the power supply wire to the lights in the instrument cluster. Enough heat was generated to damage the plastic connector, part number 12129431. The fuse did not blow. I replaced the light switch and connector.

My 2004 Impala has problems with it's light/dimmer switch. One has to click the handle twice in order to dim/brighten the lights. A couple of time the dash lights and headlights all went completely out when I tried to dim/brighten the lights. This is a hazard. There should be a recall!!!!!

I bought a used 2004 Impala in Aug. 2008 and basically since the first day I got it I have had problems with the speedometer. The dealer promised to have it repaired, but has yet to do so. They keep giving me the run around, and now for the past month my stereo has stopped working. Yesterday my fuel gauge started going haywire. The interior lights only work sometimes. The low tire pressure warning light wont reset. This is a safety problem that needs to be recalled. Because of my speedometer not working I almost went off the side of a freeway on ramp from not being able to tell how fast I was going. I just had to pray that I had slowed down enough to make the curve. Is someone going to have to be seriously injured or die before there is a recall on this. I have been to several websites researching the 2004 Impala and there are hundreds of complaints all saying the same thing. Its time that GM takes responsibility and does something about it. I am not able to have my car repaired because of the cost. It's way to expensive. I will never buy another GM vehicle.

The contact owns a 2004 Chevrolet Impala. The contact smelled gasoline in the vehicle. The dealer stated that the fuel system regulator was leaking. She smelled gasoline for over a month and took the vehicle to a mechanic. She thought the failure had been repaired; however, the odor remained. The contact then took the vehicle to a General Motors dealer and they made the repair. There is a safety recall on the vehicle, but the recall number was unknown. The powertrain was unknown as well. The current mileage was 60,899 and failure mileage was 50,000. *updated 12/12/07 the dealer stated repaired trunk light. Updated 12/12/07
