2006 Cadillac DTS exterior lighting problems

“Driving at night on I-29 South and headlights went off intermittently but not simultaneously. Headlamps continued intermittent cut-out until reached destination (approx 3 hours later). As a safety issue for driving while dark, had both assemblies replaced at Cadillac dealer for approx $3,950.00. Replacement was Cadillac recommendation as it was stated the electronics do fail in these headlight assemblies. After replacement and as a follow-up, new assemblies were installed and are not sealed against the elements. In February 2024, on a 5,000 mile trip, drove several hours during cold, snowy and raining conditions. Both headlight assemblies had a considerable amount of moisture inside the lens housings (see photo). Cadillac dealer did replace one of the new headlight assemblies due to moisture accumulation in assembly under parts warranty, but not both.”

“While driving at night in July, 2023 on [XXX] , both headlights began to go out intermittently but not simultaneously. Continued driving for approximately 3 hours to final destination. Took to local Cadillac dealer for diagnostics (Invoice [XXX]) and after dialogue with dealer had both assemblies replaced as was informed the electronics have been noted to fail in these assemblies. I replaced both assemblies for approximately $2,950.00 (Invoice [XXX}). As a follow-up, during a recent 5,000 mile trip during February 2024, driving in cold, rain, snow and road spray conditions for days, both headlight assemblies accumulated a significant amount of moisture (see photo) behind the lenses. Cadillac dealer did replace left assembly (drivers side) under parts warranty but not the right side. Both headlight assemblies are operating without incident since replacement, except as noted above on assemblies not sealed against environment/elements.”

“I BOUGHT THIS CAR, AND THE STEERING WHEEL CONTROLS(AUDIO/CRUISE CONTROL) HAVE NOT WORKED, PRIOR OWNER WAS ADVISED TO REPLACE THE BCM. FRONT DRIVER'S HEADLIGHT INTERMITTENTLY GOES ON AND OFF WHEN DRIVING. THE STEERING WHEEL SWITCH TO ADJUST THE HEIGHT, ANGLE, AND SETTINGS FOR EACH DRIVER ALSO ARE NOT WORKING. APPARENTLY THESE ARE KNOWN ISSUES. I HAD SIMILAR ISSUES WITH MY 2000 CHEVY IMPALA, AND MY 2004 CHEVY IMPALA SS.”

“MY LIGHTS I HAVE CHANGED AND TRIED EVERY THING ONLY GOT 1 TO WORK SO FAR ! I SMELL A ! BURNING SMELL ! MY POWER STEERING IS SCREWED AND LIKES A SMALL LEEK ALL ELECTRIC SOME THINGS HAS HAD ISSUES ! BLOW FUSES CIGARETTE LIGHTER STOPS WORKING CAN'T CHARGE PHONE ! BACK REAR POWER STRUTS ONLY WORK PART TIME ME L BACK UP LIGHTS THAT WARNS DON'T WORK MOST OF THE TIME ! MY KEY CAN TURN THE CAR BUT DRIVE WITH OUT KEY IN THE IGNITION THE IGNITION CAN SWITCH IT SELF ! HAVE HAD TO FIX BATTERY AND ALTERNATOR PROBLEMS AND FRONT TIRE PROBLEMS!”

“HEAD LIGHTS GO OFF BY THEMSELVES WHILE DRIVING, EITHER THE LEFT ONE OR THE RIGHT ONE. SOMETIMES EVEN WHILE SITTING IN THE GARAGE WARMING UP THE VEHICLE THE HEADLIGHTS WILL START TO FLICKER AND THEN ONE WILL GO OUT. SHUT OFF THE LIGHT SWITCH WEATHER ITS IN THE AUTO MODE OR OFF MODE AND LIGHTS WILL COME BACK ON AND MY GO OUT AGAIN. VERY DANGEROUS WHEN DRIVING. BEEN GOING ON FOR MONTHS NOW AND CADILLAC DEALER SAYS THEY HAVE NO IDEA WHAT THE PROBLEM IS AND NO FIX. WHY NOT A RECALL FROM GM AS A NUMBER OF OTHERS WITH THE SAME VEHICLE ARE HAVING THE SAME PROBLEM”

“HEADLIGHTS NORMAL (LOW) BEAM INTERMITTENTLY GO OFF WHILE DRIVING, USUALLY INDIVIDUALLY (BOTH LEFT AND RIGHT) AND ON OCCASION BOTH HAVE GONE OUT ALTHOUGH SOMETIMES ONE GOES OFF, DON'T REALIZE IT AT FIRST UNTIL THE OTHER GOES OFF.. THERE IS NO COMMONALITY (FOR EXAMPLE, CAN HAPPEN ON SMOOTH ROADS, ON BUMPS, BUT ALSO CAN GO OVER BUMPS AND LIGHTS STAY ON) AND WHEN THE HEADLIGHT GOES OUT, THE ONLY WAY TO GET IT BACK ON IS TO TURN THE LIGHTS OFF AND ON. THIS HAPPENS WHETHER USING THE AUTOMATIC LIGHT FEATURE OR HAVING THEM MANUALLY TURNED ON. THIS HAS BEEN GOING ON FOR OVER A YEAR. I'VE SEEN SIMILAR COMPLAINTS ONLINE FOR THIS PARTICULAR CAR, AND GM APPEARS TO HAVE DONE A RECALL FOR SIMILAR CARS IN THEIR BUICK AND OTHER LINES BUT NOT FOR CADILLAC.”
