Car tired keep deflating every 2-3 days. Three times stuck at different places unable to move my car, until my husband get there to inflate the tired. I have being told is the sensor valve for the tire which control the TPMS system. I call the dealer in laurel and they charge $265 for that, but many of the same car, had that problem and file a recall.this can cause an accident.

My Nissan Versa's front left passenger tire was losing air every few days. When I took it to an auto shop nearby, they found that the aluminum valve stem has cracked and that's what is causing the leak. This faulty valve stem could have lead to tire failure and potentially serious accident. Please advise how to go about addressing this issue.

The tire pressure sensor system in the Nissan Versa appears to have a systemic fault of constant leaking. I live in Wisconsin (salt in winter) and I am now forced to replace the tire pressure sensor system for the second time at a cost of $180 per tire. It appears to wear out every 2 years, leading to leaking of the tire, causing an unsafe situation.

Repeated flat tires due to air leaks which resulted in finally discovering the tire pressure monitoring valves on 3 of 4 tires were faulty. These valves were $150 each which is more than the tires cost! when took in for repairs, was told that the valves are made of metal which is prone to rust especially where they are located in the tire wells. Appears to be faulty engineering. Claim by repair personnel that a valve less likely to rust would be best but no valve available that will also meet Nissan requirements to provide tire sensor information back to the computer signal. Was told that if the sensors were not replaced could have unexpected flats or be dangerous to drive. I drive over 60 miles a day for work so safety is a concern. There needs to be an investigation about need for recall.

I just bought a 2009 Nissan Versa. While driving on a wet road and taking a corner the car lost traction forcing me to slow down to almost a halt. The stock tires (185/65R15) seem to be undersized for the high center of gravity.
