I have had ongoing problem with this since I bought the car used last august 2012. The passenger side headlamp cover gets a lot of moisture inside. I was going to fix myself so I went to "cadillac forums" and searched problem. Amazed to find all models of cadillac and always on passenger side is the moisture problem. Started in 03 model year and last questioned on 08 model year (after that warranty problem so dealer would handle. This is to much to be a coincidence and a recall should be issued. Thank you in advance. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

High beam headlights out of adjustment left side way high and to the left lights up trees not road. Right side way to high. Per cadillac and dealer no adjustment is possible. Only adjustment is on low beams, none for high beams. Complaints to cadillac went no place. After many e-mails finally talked to a real person and was offered $200.00 of service work to go away, I turned it down, per cadillac they would now close my compliant out. I drive on county roads, two lane farm county and the high beams do not light up the road ahead of my car, only tree tops to the left. Per calif law all headlights must be adjusted properly, if no adjustments is on the high beams it is against calif state law but cadillac will not do anything to correct this.

Vehicle parked in garage for 4 days. Car battery was completely drained of power. Needed to be re-charged. Dealership was unable to identify cause of battery loosing power. Problem originally occurred on september 25, 2006 same as march 2, 3007 - battery completely drained of power. Car was towed to dealership - dealership claimed problem was body control module (would cause high beams to come on when car was off) - replaced.
