My dealer only has one trained as well. But they told me any of the mechanics can work on the crossfire but the trained mechanic must inspect the job. For most of the warranty work that was done on my car it doesn't matter who does the work. They can all replace parts. The last time my car was in for warranty work they replaced the cup holder, reflashed the ECU, replaced the radio, lubricated the spoiler per the TSB. Complied with the TSB on the rear deck lid and replaced the drivers seat motors. Dropped the car off at 8 am and got a free rental (PT Cruiser) and picked up the car at 5 pm the same day. I don't bring it in till they have all the parts in stock.
