Model: 2005 Impala ,    Fail Date: Aug 18, 2008,     Location: Bristol, Connecticut

Low beam malfunction. Low beam connector completely fried. Connector melted on to the bulb. 3-5 bulbs need to be replaced each month and must take it to the auto shop to have a new connector placed on as well. Chevy would not help, said it was not covered under warranty. Dealer said that my whole electrical system would have to be re-done because there is too much power running to the bulbs. Price estimate $3500.

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.

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. 00 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.

While driving at night on several occasions myself and my wife have experienced headlight failure. It appears that there may be something wrong with the dimmer switch because when the lights do go out, manipulation of the switch usually causes the lights to come back on.

Model: 2003 Impala FWD 6-cyl,     Miles: 34,155,     Speed: 10 mi,    Fail Date: Apr 05, 2007,     Location: Covington, Virginia

Lights went off while driving at night. This happened soon,though not immediately, after flipping on the high beams. Fortunately, I was near home and not going fast,so was able to stop without incident. Somehow while playing around with the light switches, they came back on. I haven't tried to get it repaired as I can't get it to repeat the failure. This could have had serious consequences, and I suppose it may happen again.

Model: 2003 Impala FWD 6-cyl,     Miles: 75,000,    Fail Date: Mar 25, 2007,     Location: Delhi, New York

My headlights stopped working when I was out of town. Only had HI beams if I held the dimmer switch towards me. Once I released the switch, I had no lights. Took the car to my mechanic who replaced the dimmer switch with one from a wrecked car like mine because a new one from gm was $500. Also had heat/ac fan stop working. Now car is making a strange humming noise from the front end that is not coming from the motor. My husband believes the wheel bearings might be bad because our mechanic asked us if we had any problems with them. He has seen several cars like mine with wheel bearing issues.

Failure of dimmer control on 2002 Impala. Switch began feeling heavier to activate, then headlights failed multiple times, initially on high beam and then on low beam. Headlights would suddenly go off while driving. Toggling the dimmer switch would reactivate the lights. Fortunately I was driving on a fairly straight road. Dealer indicated they never heard of this problem. Review of internet complaints, this issue appears common. Repair with dealer cost $479.

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.

Model: 2002 Impala FWD 6-cyl,     Miles: 111,900,     Speed: 60 mi,    Fail Date: Dec 29, 2006,     Location: Marshfield, Wisconsin

Headlights and taillights went out while driving at night. The first time it was very momentary (just a few seconds and they again came on and functioned OK). None-the-less it caused a rapid application of the brakes. Second time, approximately 10 days or so later, same happening and rapid stop caused and pulled off to side of highway. Again the lights came on and functioned normally after about 30 seconds to a minute of time passed. Third time, approximately 2 days later, same happening only lights remained out. Was necessary to replace the dimmer switch and the cost to repair was $345.

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 headlights on our 2002 Impala will go out on their own. You can get them back on by quickly operating the high/low beam arm. When operating at night you don't dare try to switch to high beam or the lights shut off. This is a very,very dangerous situation not only for Impala owners but oncoming traffic. I took it to a local mechanic who told me the repair will likely be extensive and expensive because of the airbag . Why has there not been a recall?also the turning signal does not work properly all the time. To get this working once it has stopped you must turn off the car and restart it continually until it works again.
