I had just picked up the car from the Volvo dealership where the car was there for two weeks. I stopped for gas and did some shopping and as I was entering highway the 'tire pressure low' warning light came on. I thought it was probably due to work that was done in the shop. I entered the highway and as I was speeding up, I noticed the noise coming from the wheels, noticed that there was a flat. The flat was due to TPMS valve stem failing and as I was told later by the dealership, the loss of air was very quick and the 13 month old tire was damaged after only driving on low pressure for less than a mile. As I understand it would have been dangerous if it happened while driving at high speeds. After I took the car back to the dealership, they replaced all TPMS sensors on the car due to the Volvo tsb tj-24767 dated Dec 2011 titled 'tire monitoring system - TPMS sensor nut corrosion'. my main complaint is that Volvo knew about this issue and neither they tried to replace the TPMS sensors at a few times the car was at their dealership, nor they tried to educate the car owners about the possible risks. As a result, one of the tires was damaged which I have billed to pay for.
