I bought my new Mazda 3s on Friday and by Sunday I had no turn lights, power locks, stereo console lights, tachometer lights, working keyless entry, rear defrost or A/C, and it said my parking brakes were on even though it was disengaged. The service man said "Don't go blaming the car now, this is a common problem if you plug in an ac adapter into a Pontiac, Subaru, GMC car...." All this because I used a car charger to charge my phone?!
Blue on red tachometer lights, controls on steering wheel.
Better A/C and less anger provoking responses from dealership.
