Modern tire pressure monitoring systems are great, however the murano lacks certain easy access features that other vehicles offer. Bought new winter tires on steel rims without TPMS installed (high cost). Once installed on the vehicle the check engine light is constantly on indicating low tire pressure. Only way to remove this alarm is to get the dealer to re flash the TPMS in the car for a high cost considering the swap back to summer rims will require another re flash. Other vehicles allow you to do this yourself, not the case with the murano. It would have been cheaper to install the TPMS in the winter tires than deal with the head ache of re flashing them every winter and summer tire swap. Some tire shops will offer this service free of charge, should you get your tires swapped through them, but they must have the nissan specific tool to re flash the TPMS. The forums mention that you can re flash the TPMS yourself using a jumper to ground or paperclip on a certain connector under the dash but that sounds like a host of problems waiting to happen should you ground out the wrong thing. Choice is up to the individual, pay for TPMS on your second set of rims, pay for the re flash every time you swap (or included in swapping fee at tire shop), risk damage to other electrical components attempting to DIY the re flash or live with the constant check engine light.
