general problems of the 2003 Volkswagen Jetta

I have a 2003 vw Jetta. On numerous occasions, when I start the car and get out to scrape the snow & ice off of the windows, the door locks engage and lock me out of the running car. Since I have just left my car to remove snow, of course my purse and cell phone are in the car, so I have to leave the locked car running while I knock on neighbors doors to call someone to bring me a spare key to my house, so I can get the spare key to my car. I have not had the locks repaired, but when I took my car to gebhardt vw in boulder for other repairs, I was told the problem is so common that the mechanics roll the windows down whenever a car comes in for service, to make sure they won't get locked out. The mechanic actually had a broken lock sitting on his desk, and showed me how the lock was supposed to work, but what it does instead.

Intermittent malfunction of rear door locks. Can't open. Reporter to dealer while under warranty. Dealer could not remedy. After warranty expired, dealer recommender service. Dealer checked and verified that the problem had been reported previously when serviced(from their records). Neftin Volkswagen, thousand oaks CA.
