Wiring harness was replaced, found by parking sensor and passenger mirror fault. I noticed this problem during the initial test drive. Only replicated once out of warranty. They paid half after I proved that it was on every service request. Heater on diesel fuel additive tank, and a signal light. Started when leaving dealer after wiring harness repair. Dealer says it's a new issue and a $1,300 part. Not ready for another expensive repair yet.
