NHTSA Complaint #10210317 — 2007 TOYOTA CAMRY

TIRE PRESSURE MONITORING SYSTEM. CONSTANT ARGUING/DISAGREEMENT BETWEEN DEALER, ME, AND TOYOTA CORPORATE ABOUT HOW THIS SYSTEM WORKS/IS SUPPOSED TO WORK. DEALER SUSPECTS MY TIRE PEOPLE DAMAGE THE SENSOR. I AM INCLINED TO THINK EITHER THE SYSTEM DOESN'T WORK PROPERLY/CONSISTENTLY OR THE DEALER MECHANIC DOESN'T UNDERSTAND HOW TO PROGRAM THE SENSOR CODES. DEALER HAS CONTACTED THEIR TOYOTA SUPPORT FOR CLARIFICATION AND LEARNED LOTS FROM THEM BECAUSE OF MY PERSISTENCE AND CONTINUED MALFUNCTIONS. IN A NUTSHELL, THE MONITORING WILL NOT REPORT A PRESSURE PROBLEM UNLESS THE CAR HAS BEEN DRIVEN 20+ MILES IN A SINGLE START. I ONLY GO OVER 20 MILES IN A SINGLE ENGINE START ABOUT EVERY THREE MONTHS. SO, IT SEEMS LIKE THE MONITORING SYSTEM IS NOT PROCESSING THE AVAILABLE INFORMATION IN SUCH A WAY THAT IS RELIABLE/MEANINGFUL. FURTHER, IF THERE IS AN ACCIDENT, I DON'T KNOW IF THIS DATA IS A RECORDED ELEMENT IN THE BLACK BOX FEATURE OF THE CAR (HOW FAST, SEAT BELT USE, OTHER DRIVING INTERPRETATIONS). IF IT IS, HOW CAN THAT DATA ELEMENT BE CONSIDERED AS A POTENTIAL FACTOR (OR NOT) IF THE MONITORING SYSTEM ITSELF DOES CANNOT BE TRUSTED IF DRIVING LESS THAN 20 MILES IN ANY SINGLE ENGINE START?? I DO HAVE DIFFERENT SENSORS IN MY SUMMER AND WINTER TIRES; MY RECENTLY REMOUNTED WINTER TIRES (ON THEIR OWN WHEELS) WORKED FINE UNTIL I DROVE OVER 20 MILES LAST WEEK. BACK TO THE DEALERSHIP, TO ARGUE ABOUT THE MONITORING SYSTEM, RECEIVER, SENSORS, AND MY TIRE GUYS. *TR
