Almost immediately following a tire rotation and balance, vehicle received DSC FAULT, ABS FAULT, TRANSMISSION FAULT, AIR SUSPENSION FAULT, AND VEHICLE TOO LOW MESSAGES.
A few more facts I feel are important: my battery light came on appox. 5-6 wks following the installment of an isimple (audio AUX outlet) which just so happened to be the day I was on way to the auto shop for the tire service. AutoZone diagnostics code read, "Transmission Electrical". Withthat said Tranny does shift somewhat ruff and once (months ago shifted so hard it felt like we were rear-ended (The Rear-Ended Shift Has Only Happened Once).
