I had one light that kept fogging up from moisture. Went in for service at Cadillac and ask them about it. They said it would cost $1,700 to replace one light because Cadillac had no way to take the moisture out. They didn't tell me it would cause my light to blow if I didn't fix it. The moisture would always dry up after a few days.

One night on my way home I noticed that my lights were not on. Took it to Cadillac and asked them why both my lights were not working. They said both had moisture in them and they would continue to blow unless I spent $3,100 to change both out. They never bothered to tell me this when it was under warranty. I had no choice but to replace them. My lights would not work until I replaced the unit, they said if I replaced just the bulb, which is around $400 each, it would just blow again very soon. I have owned many cars and never had this problem. I have not had a wreck or hit anything in this car.

Update from Dec 10, 2015: I had the same problem. They told me at Cadillac that they had never seen this problem, but they happened to have the lights for my 2011 SRX in stock. Go figure. There are many people who have had this problem in a SRX

This is the SECOND time we have lost the headlights because of the moisture getting into the headlight assembly. The first time the dealership said it would be $1,500.00 per headlight to get it repaired and we flew off the handle at this news! My husband argued that he would pay to replace the bulbs in the headlight assembly all day long but that the rest of the assembly, aka the wiring problem, was on the dealership because we bought the extended warranty. So this dealership DID re-wire the headlights to get them going again, which we said would only get us six months tops before the moisture caused the same problem AGAIN... We were wrong, it only got us three months time before I was driving at night and realized that I had no headlights again. Annoying AND dangerous, but luckily my fog lamps still work (because they are separate for the headlight assembly that has the broken seal) so I had enough light to be seen by others and creep my way home.

When we called the dealership this second time around they said they wouldn't cover ANY of the headlights since this was the second occurrence and the best they could do was cut us a deal to replace both headlight assemblies for $1,500.00 instead of double that amount it would normally have cost us. NOT ACCEPTABLE for headlight assemblies that are ONLY 3 years old...am I to pay this price EVERY 3 years?!?
