Electrical system
79 reports1 crash4 fires3 related recalls
“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.”
Exterior lighting
79 reports1 crash
“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.”

“The contact owns a 2006 Cadillac DTS. The contact stated that a recurring power steering failure had occurred at startup, and the steering wheel was firm. The contact stated that upon adding power steering fluid to the power steering reservoir, there was an immediate power steering fluid leak. Additionally, the brakes and check engine warning lights were illuminated on the instrument panel. The contact associated the failure with NHTSA Campaign Number: 06V105000 (Steering). However, after contacting the manufacturer, the contact was informed the vehicle was not under recall. The vehicle was not repaired. The contact was referred to a local dealer for potential assistance from Goodwill. The failure mileage was approximately 192,000.”

“I called OnStar because my car would not start and they sent someone from GM. The guy looked at my car, could not identify the problem, so I got it towed to a repair shop. Ends up, I had to replace the transmission. The repair shop ran electric test on the vehicle and no codes or issues. My dash is now reading service power steering and this is a safety issue that needs to be fixed by the manufacturer.”

“TODAY I HAD THE GM RECALL 14299 PERFORMED ON MY CADILLAC DTS AT MY LOCAL CADILLAC DEALERSHIP. THE REPAIR TOOK ABOUT 1 HOUR AND THE CAR WAS RETURNED TO ME WITH THE INSTRUCTIONS FROM THE DEALERSHIP THAT ONE KEY HAD A "CLAMP" ON IT AND IF I REMOVED THE "CLAMP" AND THE NEW KEY INSERT DID NOT STAY IN PLACE THAT THEY WOULD NEED TO "FIGURE SOMETHING OUT". I WAITED AN HOUR FOR THE GLUE TO DRY AND ATTEMPTED TO REMOVE THE "CLAMP" AND THE INSERT WAS ADHERED TO THE CLAMP AS IT APPEARED RESIDUAL GLUE HAD STUCK TO THE FACE OF THE INSERT AND THE UNDERNEATH SLIDE OF THE CLAMP. I THEN WENT TO PUT A KEY CHAIN ON MY GM VALET KEY AND THE INSERT POPPED OUT OF PLACE ON THAT KEY AS WELL. I HAVE NOT YET CONTACTED THE GM DEALERSHIP, BUT THIS RECALL REPAIR IS VERY TROUBLING AS IT DOES NOT APPEAR THAT THIS REPAIR WILL HAVE THE LONGEVITY NEEDED TO STAY IN PLACE AND PROTECT THE CONSUMER. I HAVE PHOTOS OF THE KEYS IF NEEDED. *TR”
