There were no events that lead to this failure. With all fuses operational, I do not have any dashlights illuminated at night. I have to use my cell phone light to place over my speedometer cluster panel to view my speed, gas levels and any warning lights. This has been ongoing for a little over a year. When my daytime running lights are on, they blink constantly and other drivers think I am experiencing an emergency. If I use my interior lights, they flash like I am trying to signal for help. Same if I open the visor to use the lighted mirror. I have not had this repaired since gm will not guarantee a resolution with a repair. I cannot afford to keep giving money to gm dealerships without a repair. This is very dangerous for me at night, I cannot use my cruise control everywhere. My traction control will not disengage either.

I have a 2002 chevrolet impala ls. Bought used in 2005 had 72,000 miles. It now has 89,800 miles. Since I have had the vehicle I have had to replace the bcm module, rebuilt transmission, replace the PCM module, replace all four rotors along with brake pads all around, and now my left turn signal has stopped working intermittently. The right turn signal works fine. When the left turn signal is working the hazards work fine as well, but when the left isn't neither does the hazard lights. Along with the problem it disengages the traction control, which therefore disengages the cruise control. I read on a forum that replacing the hazard switch will fix this problem however not my case. I have been told to replace the turn signal module, but the part is 299.99 plus labor or the dealership told me they could troubleshoot the problem, but at astronomical labor charges. From all the forums I've read and my own problems the 2000-2002 impalas are nothing, but garbage! This will be my last american made car! Very very disappointed chevrolet customer.

Cruise control not responding. Sudden lunge/acceleration caused car to speed off the road. Driver injured, car totaled. Suspect cruise control later kicked in, some 40 miles down the road, causing sudden acceleration and subsequent accident.

When using my cruise control, turning it on and canceling, there is a clunk. Brought it to the dealer under warranty and said based on another chevy impala it was normal.

When using the lane change feature on the turn signal lever, instead of flashimg at same speed as when using the turn signals, the flasher (at times) would flash at a rapid speed similar to when a bulb would be burned out in the tail lights. Consumer had a new switch put in, but that didn't remedy the problem. The consumer along with a dealer rep, had tested other of the same vehicle make, and noticed that one had acted the same as the consumers vehicle, with the cruise control switches on the turn signal lever. The one that acted properly did not have cruise control on the turn signal lever.
