Thanks for the replies guys, really appreciate the help here. So I started my car this morning and no low tire pressure light BUT it did come on for a split second and then disappeared again. Any idea what that might be? Is it a "check" by the TPMS? I don't recall seeing that when I first got my car.

 

Got an actual tire pressure gauge? If not, then get one.

Measure the tire pressure yourself & watch that one tire. The TPMS warning doesn't go off until it's a few pounds low. With a gauge you'll see that coming long before the idiot light goes off.

 

Leaks no necessarily can be on the tread area. Perhaps is a small leak around the rim.

Before worrying so much about this issue, if the low pressure happens to me even once and regardless of how new is the car or the replacement of a tire, I just take water with soap and check for tire leaks by myself. Doing so, I won't buy any story the mechanic might tell about the cause for the low pressure.

 

Yeah, checking with soapy water, looking for bubbles, takes less time than driving to the dealer. Don't forget it might be leaking around the valve stem, or around the bead of the rim, and don't forget the inboard side of the rim too.

 

Really appreciate the help here guys. But I am not techy at all so I rather take it to the dealer and have them take a look at it. I live 5 mins drive away from the dealership so it's ok.
