Went to the dealer today to get an extra Fob and key (ouch) . I brought up a couple of isses with the service manager like the Hemi tick and erratic idle. I need to bring the truck back to address those issues, BUT he told me that I need to wax my back bumper regularly. There were some signs of rust starting around the sensors. Apparently he has changed out quite a few on the 2010/11 models due to inferior plating. I cant believe that at 3500 miles My motor tics, truck idles like crap and my bumper is starting to rust. I expect this from a japanese truck but not Dodge. OK I gotta go, need to hurry out and wax my bumper, rain is on its way.
