I am having an issue with my 2016 Grand Touring CX5. The tire pressure warning light and emergency brake warning dash lights came on after Costco installed new tires. Now they won't go off and Costco says I need to take it to the dealer. The dealer Service dept. is charging me $500.00 to "investigate the problem" After having my car the whole day the Mazda Dealer service dept. called me to tell my my emergency flashers and turn signals are not working and this is probably related to the tire pressure warning light issue. Which is really strange since they worked when I had to pull over (on my way to the dealership) to let my puppy out to go potty by the side of the road.
Anybody else experience this kind of problem? Any feedback would be much appreciated.
