Electrical system

79 reports1 crash4 fires
“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.”
