NHTSA Complaint #10356349 — 2007 NISSAN MURANO

TIRE PRESSURE MONITORING SYSTEM (TPMS) IS DEFECTIVE. THE PRESSURE INDICATOR IN MY VEHICLE CONSTANTLY LIGHTS UP TELLING ME MY TIRES ARE UNDERINFLATED. I HAVE CHECKED THE TIRES WITH THREE DIFFERENT TYPES OF PRESSURE GAUGES AND THE READING IS THE RECOMMENDED 32 PSI BUT THE CAR SAYS 27 PSI. WHEN I TOOK THE VEHICLE TO NISSAN THEY TOLD ME TO OVER INFLATE MY TIRES TO 37 PSI WHEN THE PLACARD IN THE DOOR SAYS TO INFLATE TO 32 PSI. BASICALLY THE TPMS IS OFF BY 16% WHICH I BELIEVE IS A SAFETY CONCERN. EITHER I OVER INFLATE MY TIRES, RESULTING IN LESS STABILITY AND UNEVEN WEAR, OR I IGNORE THE WARNING LIGHT AND TAKE THE RISK THAT I MAY DRIVE OVER A NAIL OR OTHER ROAD HAZARD AND NOT KNOW ABOUT IT. I FIND THE PROBLEM ESPECIALLY INTERESTING WHEN YOU SEE THAT ON ALL OF MY NISSAN MAINTENANCE WORK THEY REPORT THEY INFLATED THE TIRES TO 33 PSI, WHEN IN TRUTH THEY INFLATE IT TO 36-37 PSI SO THAT THE LIGHT WILL NOT COME ON. I HAVE NOTIFIED NISSAN ON 11/28/2008 BUT NO AVAIL. IT SEEMS THAT THIS IS A COMMON PROBLEM FROM MY SEARCH ON THE INTERNET AND I HOPE YOU WILL LOOK INTO IT. *TR
