It was fixed by mechanic I bought car from. 2 weeks later same problem. Smelled burning in car. ONLY high beams. I know a lot of people with issue but never reported it.

This problem occurred while driving, the low beam lights shut off completely. This happened on a dark unlit road at night and caused me to not see the road. I had a small crash before bringing the car to a stop because I could not see the object in front of me as I was pulling over. The car was not damaged from this crash, but it would have been avoided had their been headlight.I have spent $850 repairing this problem without a solution. I replaced the multi-function switch which controls turning signals and high-beams. I have traced the problem to either a BCM or wire failure near the battery and radiator. The relay which controls headlights comes on, daytime running lights come on and high beams work. What looks like has happened is the wiring harness behind the battery has become corroded. There are MANY different vehicle functions controlled in this harness. Also this is a common complaint with GM vehicles. I see many people driving around impalas with their high-beams activated or no headlights at all.
All in all, very happy with my Impala. Fast car with the 3.8L, rides and handles well. Only problem was a one time problem with the lights. Cost nothing to fix, and the problem has never re-occured.
This is the second time this has happened. A year ago, they would go out when dimming. Playing with the dimmer switch would bring them back on. We put a new switch on the steering column and they still did it occasionally. Last night they went out and would not come back on. The only way we could have lights was to manually hold the dimmer switch on high beam (the only beam which would come on). We are elderly and this has been a huge problem, almost causing us to leave the road last night. We don't know what else to have done without going to a lot more expense.
My day time lights work fine but as soon as it gets dark and the damn headlights are suppose to come on automatically the day time lights cut off and the night headlights dont come on. How the hell do you put a sensor in a car that can cause an accident and dont put a manual switch just in case something goes wrong at night and you are driving out of town.
