GPS, Tire Pressure Monitors, Cell phone pairing all FAIL
First the GPS started providing seriously INCORRECT turn directions. Next, EVIC reported my tire pressure emergency but actually the sensors stopped working. Finally, the cell phone pairing periodically failed one day and reconnected another day repeatedly. Yes, it was very disappointing and a pain in the arse.
Today, I took the truck in AGAIN reporting all the problems. After two hours, I got the truck back. What was the problem, I asked? Turns out the last time I was in for service, the dealer had updated EVIC and the 8.4 radio. Apparently, the update was not successfully downloaded and the system became erratic. Everything was downloaded and reflashed. I am hoping all the problems will be history now.
