The door locks intermittently lock with key fob and sometimes do not unlock. It's very random. If you lock them all by hand, a different door or doors will unlock with the key fob.

The same thing has happened to my car as well, the rear door lock has stopped working. It tries a couple times to open then quits. Sometimes can't even use manual open.

Both the front passenger door & the rear driver side door stopped at the same time & no longer works, we were advised $750 each door to repair. Also, the air conditioning unit dissolved & had to be totally replaced. Along with the heating & a/c unit for the front passenger seat. It seems to me that the entire electrical system is faulty. Cadillac has definitely gone down in quality & will not be purchased by us again.

My 2008 Cadillac EXT doors will not lock or unlock. When I first bought the truck new the rear passenger door lock was replace and two days later the I noticed the front passenger door had the same problem. I assumed they just switched the locks from front to back and didn't replace it. Now all locks don't work. I am so aggravated by this. I must look really attractive reaching in back to lift up the locks.
