2003 GMC YUKON DENALI Electrical Systemwiringinteriorunder Dash Problems

HAVING ELECTRICAL PROBLEMS WITH THE VEHICLE. SEATS WILL MOVE WHILE DRIVING,HEATER IN SEATS COME ON WITH OUT LIGHT INDICATING THAT THEY ARE ON. AIR CONDITIONING SPEEDS WILL VARY.THERE ARE TO MANY PROBLEMS. BUT THE MAIN ONE WAS PUTTING THE CAR IN DRIVE AND IT WOULD GO INTO REVERSE.*AK

WHILE DRIVING AT NIGHT THE HEADLIGHTS AND DASH LIGHTS FLICKER OFF AND ON. THIS CONDITION ONLY OCCURS WHILE TRAVELING AT SPEEDS ABOVE 35 MPH AND WHEN HITTING A BUMP OR MAKING A CURVE. THIS CONDITION IS NOT ONLY DISTRACTING, BUT WHEN DRIVING AT NIGHT WITH NO OTHER AMBIENT LIGHT I AM UNABLE TO SEE ADEQUATELY AHEAD OF MY VEHICLE. I HAVE HAD DRIVERS AHEAD OF ME PULL OVER THINKING THAT I WAS FLASHING MY LIGHTS AT THEM AND OTHER DRIVERS GET IRATE BELIEVING THAT I AM "BRIGHT LIGHTING THEM". THIS IS A SAFETY ISSUE THAT APPEARS TO BE WIDESPREAD ON THE DENALI'S WITH STABILITRAK. GM STATES THAT THIS CONDITION IS "NORMAL". I BELIEVE THAT HEADLIGHTS ARE MEANT TO BURN STEADY AND NOT FLICKER OFF AND ON. I AM REQUESTING THAT NHTSA INVESTIGATE THIS WITH THE AUTO MANUFACTURER TO MANDATE A FIX BEFORE THERE ARE INJURIES ATTRIBUTED TO THIS CONDITION.*AK
