Since my selling dealership has been closed since 2009 and they were awesome to deal with, sales, parts and service, never had a problem, I now split my business between two dealerships, Lapeyrouse Motors in Jeanerette, LA and Acadiana Dodge in Lafayette, LA.
I have had some issues with Lapeyrouse in the past on another vehicle (shoddy work for what they called a "deal" of a price, vehicle returned dirty/greasy and a nice scratch in a door that they refused to admit they had done even though it was not there when I brought it in), they are relegated to oil changes/maintenance.
Acadiana Dodge handles any mechanical/warranty issues (they did the second pinion seal under warranty in 2010 and my evaporator core in December of that same year). If you don't want a loaner vehicle and would rather wait, they have a shuttle service that will drop you off somewhere and pick you up when your vehicle is done. They listen to your concern and work to get to the bottom of the symptoms you describe. Service gives you an estimated time frame to complete the repair and they come out ahead of schedule, well worth the hour or so drive to deal with them!
