Many of the repairs to current model year Chrysler vehicles require software updates to complete. These updates are only available through Chrysler's portal called DealerConnect and TechConnect. Unless you work at a dealership, you have to pay for a 48 hour window in which you can access these websites and obtain the software needed. Many independent shops refuse to pay the money required to do that.
So basically, many shops simply cannot fix modern vehicles because they do not have the knowledge, equipment or permissions to do it.
