I had a dead battery upon leaving work on Friday. I may have unknowingly left in ACC when I got out of the car around 2PM. By 5PM when I returned it was completely dead. After dealing with the morons at the road side assistance line, I finally got a jump start. I drove around ~ 15 miles to get a good charge on the battery. All seems to be fine except I have the tire inflation icon lit on the dash. I checked all 4 tires and get ~ 35 PSI -about 2 psi above the nominal reccomendation. The icon only appeared after the battery jump. Anybody have a similar experience?

 

i have an 08' g37s and i had a battery issue and they told me that the battery that they put in the g37 were too small to hold a charge, so they ran a few tests and gave me the battery that came on the m class. they also replaced the vent control valve. its all under warranty so you should get it for free like me. but the tpms light.... i have no idea. hope this helps.

 

Tons of threads on this. Very common and covered under warranty.
