I have a 2007 Nissan Altima and got new tires on the car at NTB back in December, so about 10 months ago. A week after I got the new tires on, the low tire pressure light came on, took it back into NTB and they said it was because of the cold weather. It happened a couple more times and I filled them up with air. When it happened the next time, I took it in to NTB and they said that I needed a new tire pressure sensor because it was allowing the tire to leak. I got that done and in the process, they told me that the whole tire was bad. So, I had to get that replaced. Recently, they told me another tire was leaking b/c of the sensor and I had to get a new sensor. I got a new one and now a week later, the tire pressure light is on again. I am trying to figure out if this is a problem with Altimas and their sensors or if NTB put faulty tires on and messed up the sensors in the process? Any feedback would be appreciated! Thanks!
