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 (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.

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. 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.

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.

So we bought the car. In 2012 or 2013. And in 2014 we received a yellow letter in the mail saying that our car needed to be serviced for a recall. We set it up. Ended up taking it in To be serviced for the recalls. Not knowing in 2008 they recalled what is now going wrong in the car, I didn-??t say anything at the time we repaired it. It they didn-??t either I believe and even if we didn-??t say anything they honestly should-??ve just repaired the part that was messed up for us and then let us know: now we have spent so much money towing our car back to our house so that it is safe, and have missed appointments, been stranded, I mean we have really, honestly and truly, very very compromised but this issue with the electrical system Our car is having all the time since this recall repair was administered: NOW IT HAS JUST GOTTEN SO BAD WE CAN NOYT EVEN DRIVE IT. We will get stuck where ever we turn it off unfortunately. I-??ve not looked online at information taken all the necessary needs to find out if my vehicle was given the recall before we owned it just to be sure too, it was not. I know that everything that I have read relates directly perfectly to Every single issue that we are have ig Now on our car. The recall from 2014 the key doesn-??t come out the ignition anymore and that-??s very good, but I know that The CADILLAC Dealer, DID NOT!! Install any other part into the car but that service it asked for. Like beyond a doubt I don-??t know what to do and would love to be able to get some answers soon. Thank you very much.

The drivers side headlight shuts off and on or flickers - most noticeable during night time driving. Our dealer, ed shults Chevrolet, advised us that this particular model of the Cadillac cts was not under recall. We wanted an explanation as to why when all of the testimonials from other 2006 Cadillac owners reported the same problem. They dealer stated it had to do with where the car was manufactured. The total charge to us was $901.80 to replace the light + labor. This was probably happening all the time we were driving but we only began to notice it during night time driving, most especially driving back from the buffalo international airport on the thruway. We live in the city of jamestown, NY so it wasn't really noticeable because of the city lights. After that, we were more diligent when driving at night and discovered0 it was on a daily thing. That was very scary.

As part of state inspection, told dealer that front seats are not heating. Told by dealer that problem was "connector to climate control seat module burned/shorted out module" and to replace connector and module would cost $1016. Asked dealer personnel if a safety issue and they said it is a routine/recurring problem with these components melting from the heat but don't worry it's not a safety issue (despite reference to " burned/shorted out"). internet search showed similar problem with same components in other Cadillac but accompanied by/with smoke and/or fire-- if occurs while operating vehicle at a high speed on a busy street or highway, could result in a major accident involving serious injury or death. Needs to be investigated.
