NHTSA Complaint #10551781 — 2006 CADILLAC DTS

WHILE ON A TRIP IN WISCONSIN, I WAS TRAVELING AT NIGHT ON A 4-LANE HIGHWAY WITH TWO FRIENDS IN THE CAR AT A SPEED OF 65 MPH. BOTH HEADLIGHTS WENT OUT WITH NO INDICATION OF FAILURE ON THE DASH. THANKFULLY, WE WERE THE ONLY ONES ON THE ROAD. I SLOWED DOWN AND PULLED TO THE SIDE AS BEST AS I COULD SEE. UPON STOPPING THE CAR, I SWITCHED THE LIGHT SWITCH ON AND OFF SEVERAL TIMES UNTIL BOTH HEADLIGHTS CAME ON AGAIN. I PULLED BACK ON THE ROAD TO PROCEED - AGAIN NO INDICATION ON THE DASH THAT ANYTHING WAS WRONG WITH THE HEADLIGHTS. A FEW MILES DOWN THE ROAD, ONE HEADLIGHT WENT OUT. I SWITCHED THE HEADLIGHTS ON-OFF SEVERAL TIMES AND BOTH CAME ON AGAIN. I TOOK THE CAR TO THE DEALER ON 28SEP2009 AND THEY REPLACED BOTH HEADLIGHTS UNDER WARRANTY. A FEW WEEKS LATER ON 4DEC2009, I RETURNED THE CAR TO THE DEALER BECAUSE THE RIGHT HEADLIGHT CONTINUED TO GO OUT WITH NO INDICATION ON THE DASH. THE DEALER REPLACED THE RIGHT HEADLAMP AND I HAD NO FURTHER PROBLEMS UNTIL RECENTLY. I RETURNED THE CAR TO THE DEALER 8NOV2013 BECAUSE THE LEFT HEADLIGHT WOULD GO OUT, COME BACK ON, GO OUT, COME BACK ON, ETC. WITH NO WARNING OR INDICATION ON THE DASH. THIS IS A BIG SAFETY ISSUE!!!!! IF YOU READ SOME BLOGS ON THIS PROBLEM ON THE INTERNET, YOU WILL FIND THAT THIS IS NOT A UNIQUE CASE - AND THERE IS NO EXPLANATION WHY IT OCCURS. IF THE HEADLIGHTS GO OUT, YOU SHOULD GET AN INDICATION ON THE DASH THAT A LAMP IS BAD. CERTAINLY, BOTH LIGHTS SHOULD NEVER GO OUT AT ONCE WHILE YOU ARE TRAVELING. IT IS EXTREMELY EXPENSIVE TO REPLACE HEADLAMPS IN THIS CAR >$550 PER LIGHT!!!!! MORE IMPORTANTLY, I CANNOT BELIEVE THERE IS NO INVESTIGATION INTO THIS PROBLEM. *TR
