TPMS Light After New Tire Install
I have a 2008 Cobalt. Last month, I bought new tires from Pep Boys. A week later, my Tire Pressure Monitoring System light started going off, and I discovered that one of my tires wasn't sending a pressure signal. Every time I would make an appointment to go get it checked out, the light would disappear. They claimed they couldn't make a diagnosis without a warning light.
Well, I finally went into the shop when the light was on. They claim that the battery in the unit is dead. This is despite not having any issues with the system since I bought the car in 2010. The guy claimed that the batteries start to die around 6-7 years, and that I should get them all replaced since the others are likely to start going bad. It would be $100 a piece. I declined.
Is 6-7 years the typical life cycle of TMPS sensor batteries, or do you think I was being played (since the life cycle magically lines up with the age of my car)?
