The contact owns a 2004 Chevrolet Impala. While driving approximately 45 mph in the evening, the exterior headlights on both the driver and passenger sides failed. The contact stopped the vehicle and turned the dimmer switch on and off, which allowed the exterior lights to regain power. The vehicle was driven to the contact's residence. The following day, the vehicle was driven to the dealer and they stated that the dimmer switch needed to be replaced. The dimmer switch was replaced that same day. The manufacturer stated that there was no recall; therefore, they were not liable for the repairs. The current mileage was 67,924 and failure mileage was 67,919. Updated 12/30/08 updated 12/30/08.

I have a 2004 Chevy Impala that has had problems with warped rotors, which I had replaced. Then a wheel bearing went bad. Took vehicle to Chevy dealer. They diagnosed it as left front hub bearing being bad. I had left front hub bearing replaced and problem wasn't fixed. Turned out it was right front hub bearing that was bad, so both ended up replaced. A few weeks later "service traction system" light started coming on every day and shuts off the ABS and traction control systems. Outside temperature and weather conditions don't make any difference. Also having problems with headlights going from high beams to dim. Sometimes it takes two or three attempts before it will go from high beams to dim. I've never had these kinds of problems with Chevrolet's before. I've had Chevrolet's with 150,000 miles on them and have never had to replace rotors, wheel bearings, or had ABS problems before, just normal maintenance.

Problem switching from high beam to low beam etc and sudden headlight failure at night while driving down road. Believe problem is multi function switch which has been reported by numerous people for this vehicle type. Started out as infrequent but getting progressively worse.

Multifunction switch on steering colum failed, as a result I have no highbeams, if I attempt to put them on all lights go out, this is a very expensive problem that I think General Motors should come good for.

2004 Chevrolet Impala. Headlights suddenly stopped working completely while backing out of my driveway onto my road. While I was able to pull back into my driveway quickly, it would have been another story a minute later when I would have been at a busy intersection. Because there was no accident or injuries, does not make this any less of a serious safety related failure of this vehicle. If the police can ticket you for not fixing one headlight when it fails, why would this not be a more serious safety problem? I had the vehicle in to the GM dealership where they determined that the multifunction switch (on the steering column) had failed. It was replaced and it cost me $786 Canadian. My wife told me that the lights had gone out a few weeks prior to this while driving home one night. They suddenly went out for a few seconds and then came back on by themselves. I am assuming this was caused by the same malfunction.

Wow same problem as everyone else. Speed does not register properly seems to be whenever it wants it will show speeds higher then what they are. This is a danger because speeds are guessed in school zones and highways. After a couple days speed will begin to work ok. Now the blower motor and heater do not work unless you pound by the ashtray area and hopefully the air conditioning will start blowing but the heat will not come on when switched to heat. This is a safety issue living in Montana when it gets below 32 and colder it would be nice this winter to thaw out the windows so I can see when driving at unknown speeds. Sometimes when the air is blowing you can smell something burning. We are in drought conditions in Montana and if my car were to catch on fire on side of road and continue up the mountains this could be a disaster be creating a wildfire. I am unhappy with my car which has started problems around the 30,000 mile mark. Another problem is the high beam switch is needing to be clicked twice before dimming down from high beam. This is a safety issue due to blinding oncoming traffic. Transmission has been like slipping into gear as well.

The blinker switch malfunctions from bright to dim, sometimes goes black.

Driving at night, headlights turned off on their own. Pulled forward several times on the dimmer switch and they came back on. If the dimmer switch is on lo-beam & switched to hi-beam, occasionally there is no "click". this is when the lights go off. If I hear the "click" the lights have not failed. Will schedule appointment with dealer to correct the problem.

I lost my bright lights on my 04 Chevy Impala. My daughter had filed the same complaint on her 04 Impala also in Oct. Of 06. I now have to get my dimmer switch replaced, and I know you had a recall on the 02's, why not the 04's also?
