Brake Abs Warning Light problems of the 2005 Chevrolet Impala

Hi I purchased my Impala last year used and for about the first 6 months it ran fine. . . Now electrical panel goes on the fritz dimming my lights and dashboard. . . Power windows and mirrors not working. . . Also abs light and traction lights on consistently. . . Traction randomly activates and car lighters just stopped working. Something is wrong with this specific model and it really needs to be recalled. Also turn key to start car and the car doesn't start so I do this 2-3 times to start car up. . . Really needs to recall all 2005 Impalas.

Recently, I have been having trouble with my 2005 Impala and the abs/traction system. At the beginning, the "abs, traction off and service traction system" lights would come on. The abs and traction lights would stay on and the service traction was intermittent. The car also makes a loud "dinging" sound when the lights come on. When I would make a turn, the car would also make a grinding sound and the service traction light would come back on. Eventually, the traction began kicking in when it was not suppose to and the car would not stop properly. This of course was a serious safety issue. I have researched this problem and found complaints upon complaints about this same problem. I contacted gm and they told me they never heard of this problem which I find hard to believe. I have spent an enormous amount of time and money trying to fix this problem. My local dealership wanted almost $4,000 for repairs. I then took the car to a very reputable repair shop and they, like two other shops I checked with, told me they have seen this numerous times in these cars. They attempted to fix the problem but the problem still exists. I spent $2,000 having the wheel hubs, abs harnesses and brake pressure modulator valve replaced. The lights, although intermittent, are still coming on! sometimes it is when I turn the car on, back up or even just driving down the road. This car only has 77,000 miles on it and I feel I should not be having this problem. I have had to take it back twice and they are still attempting to find the source of the problem. This is the only major problem I have had with this car. Any assistance you could give me would be appreciated.

Tl-the contact owns a 2005 Chevrolet Impala. The contact stated that the abs traction waring light remained illuminated and when the brake pedal was applied she would hear an abnormal noise. The independent mechanic diagnosed that the abs light needed repaired. The vehicle was replaced but the failure recurred. The manufacturer was not notified. The approximate failure mileage was 149,000. Ne.
