There is a Volvo recall 226 (NHTSA campaign #10V190000) to replace an incorrect FMVSS label that shows tire pressure of 33 psi and to replace a page in the owners manual that shows the pressure should be 35 psi. The correct pressure is 36 psi. This is information is also contained in a letter from Volvo to NHTSA dated 4 May 2010 (10V-190 3 pages). According to Volvo, our XC70 (mfd 8/09) is not part of this recall. However, the tire pressure on the FMVSS label and listed in the owners manual match the information in the recall. Since the information on the FMVSS label does not match what is listed in the owners manual for our XC70, Volvo needs to 1) include our XC70 in the recall or; 2) issue a new recall or; 3) inform us how the two different pressures (on the FMVSS label and owners manual) are correct.

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.

Driving on the interstate highway there was a sudden loss of tire pressure. This was caused by a failure of the tire pressure valve due to corrosion of the metal. The new valves are made of plastic. However, the issue is that one doesn't know about the problem until it occurs. If the front tire had loss pressure there may have been a worse incident. This had previously occurred about 6 months earlier with another tire. I stopped to add air to a tire and discovered that the valve was pushed into the tire when tried to apply the air hose. The tire valve was replaced, but I didn't think anything of it at the time. This time around I had all of the original valves replaced, and found that the dealers in the area are all out of stock with the valves, so it appears to be a universal problem. I believe that the original valve can be characterized by a defective design with respect to the materials used. As a result, I have had to replace two damaged tires, as well as four tire pressure valves due to this issue. My suggestion is that the issue should be quickly investigated for a possible recall and replacement at the expense of the manufacturer. Thank you.

The contact owns a 2010 Volvo XC70. While driving approximately 80 mph, the rear passenger side tire deflated suddenly. The vehicle was taken to the dealer for diagnostic testing. The technician advised the contact that all four valve stems were cracked and would have to be replaced. The vehicle was not repaired. The approximate failure mileage was 22,000.
