I was driving my car when the tire pressure light came on
(!) and started blinking. And my car completely stopped in
the middle of the street. I was able to turn it back on, but
now the car doesn't turn on at all. Every time I try and
start the engine the (!) just blinks. I have no idea what's
going on... The dealer says I'm no longer under warranty
so they can't help..
Your TPMS issue should indicate low tire pressure on one or more tires on your car. It should have nothing to do with your car shutting down without warning. Time to have a mechanic look it over. Surprised the dealership didn't want to help you.
The dealer can too help it is just that you will have to pay for it. I think you have more than just 1 problem though, the TPMS will not prevent the engine from starting and driving the vehicle. The TPMS sensors will last anywhere from 5 to 7 years and you almost at 5 years depending on the build date of your rig. Have you checked the security system cause it sounds like it has been activated.
The alarm has been going off for no reason. And sometimes it also prevents the car from starting. But eventually it would... I just find it weird that the (!) is blinking because it's never done that before, and it blinks when I try turning the car on.
That is the way it works when there is a problem with the tire pressures or the sensors. Your security system is your other problem with the not starting, possibly a failed door switch, it only takes 1 to shut down the whole system.
