Last year around this same time I was driving to work around 4:30 am on I 85 nb in atlanta, ga. Going to work when my car suddenly went totally dark. I didn't realize it until I got to a stretch of highway that had no lights. It was very scary cause I didn't know if any of the other cars could see me. I got off the hwy at the 1st exit and waited until daylight to go continue to work. I went to the 1st mechanic that opened and the lights were working again so the mechanic couldn't find anything wrong. 1 year later on 2/12/08, my 7year old son and I went to the drug store to get his medication and as we were driving up sr 139, I noticed that I couldn't see the road!!! again, I'm on a stretch of road with no street lights and this time I have interior lights, blinkers and parkers, but I have no headlights. I immediately pulled over and cut the car off hoping to reset the computer or whatever was causing the problem and when I restarted the car the headlights still didn't come on. I waited approx 45 minutes and still in the dark. I was sooo afraid because I had my son with me and I had about 2.5 miles to go before getting home. I took my chances and drove home trying to be as careful as possible as oncoming cars flashed their lights at me and honked. My son was scared and kept asking if other cars were going to hit us or if they could see us. I tried to stay calm for him, but truthfully, I was scared stupid. I've been reading up on similar situations like this and GM has got to step up and fix this problem. Why should it take for someone to loose their life for GM to take notice"?" I've owned a 99 Grand Am, 00 Oldsmobile Alero & now the the 04 Impala. I thought that I had moved up and bought a really good car that I loved not a death machine. My next car might have to be a Nissan or a Toyota. My grandma & mom only buy Toyota and have never had these types of problems. But I'm trying to keep my fellow americans employed even though I've lost my job.

While driving with hi beams on the headlights will repeatedly shut completely off. I have to move the hi/low beam lever and the low beams will come on. This can be very dangerous since I live on un-lit country roads. This in not an occasional problem, it happens every time the lights are on.

Last winter I was driving to work on a dark morning and without warning my headlights went totally out. I kept flipping my headlight switch off and on and my dimmer switch until they came back on. I continued down the road and it happened repeatedly until I got to work. Took it to the dealer, they replaced a computer module. I didn't think to much about it until this morning when it happened again. It has been cool or cold out both times it has happened so I don't know if it has anything to do with temperature or not. I have lost time from work because our area auto dealers service depts. Are not open on saturdays, not to mention the danger of driving a black car in the dark with no headlights!

Driving along at night with headlights on and they just went out, luckily, there was a bright moon and straight highway, happened 3 more times on way home, approximately 10 miles. After turning car off and on, lights off and on, they would come back on. Have not driven it after dark since then. Experienced more problems.

Chevy 2004 Impala for no reason the head lights will turn off and will not come back on... I have been caught several times in very dangerous roads when this has happened.... thankfully no crashes or injuried. I called Chevy several times and they can't tell me why it happens or how to fix it.

I was driving home one night at about 9:30 in the country and it was pitch-black when all of a sudden my headlights go out. I had to be going about 55 mph when this occurred. They wouldn't come back on until I pulled the dimmer switch in and out repeatedly. Luckily I was familiar with the area to come to a stop without incident. Within the next couple of days I will be taking my car in to a dealer and get an inspection.

- Spring Grove , IL, USA

: the contact stated the head lights fail intermittently without warning. The problem began four months ago and the vehicle was taken to service dealer who replaced an unknown module. The problem has now returned and the head lights go out without warning and re illuminate without warning. Manipulating the switch does not automatically make the lights re illuminate. The contact is planning to make an appointment with the dealer later today for inspection. The vehicle is a police cruiser.

The new model year 04 Chevrolet Impala sedans have poorly designed and or mis-adjusted daytime running lights, causing blinding glare to on coming drivers, drivers in front of these vehicles and pedestrians walking at night. These excessively glaring lights distract and cause eye pain to other drivers and temporary blindness. This is a serious safety problem that needs to be addressed especially for pedestrians walking against traffic at night.
