Mazda MAZDA5 owners have reported 4 problems related to tire pressure monitoring system (under the tire category).
While checking the customer's tire pressure as part of an oil change service, the valve stem broke. The valve stem was part of the tpms sensor resulting in the tire going flat and the car to become inoperable. A new tpms sensor was procured and we (the service center) had to pay the $205. 77 to repair the fault.

While driving at 70mph on us23 in michigan, tpms low pressure telltale illuminated. Within 30 secs, vehicle began to pull hard to the left. Pulled off the side of this 4 lane 70mph highway in the rain to investigate. Left front tire completely flat. Nut holding the tpms sensor to the rim was missing & had corroded, allowing the tpms sensor to fall inside tire cavity, resulting in rapid air loss. Threads of tpms sensor exhibited corrosion. Drove vehicle to GMC dealership in milan mi which confirmed the tpms sensor nut failure due to corrosion. Tire destroyed, rim edge chewed up. Contacted Mazda USA and they would not offer any consideration, stating that the 3 year warranty had expired 1 month prior, and that corrosion was not covered beyond 3 years. I stated that this isn't a cosmetic rust issue, that the corrosion resulted in a safety concern for me and my family, but Mazda would not offer any resolution. The vehicle has been driven during 3 mild ohio winters; there is not any signs of corrosion anywhere else on the vehicle; I drive the car thru automatic car washes every 3 weeks or so in the winter just to wash off any road salt. No other component on the vehicle is exhibiting corrosion. Had vehicle on lift to inspect the underbody. It does not seem technically sound that a vehicle component specifically mandate by NHTSA to prevent tires from being ran low in inflation pressure on a vehicle should instead cause my tire to rapidly lose all air pressure. This is a safety issue. I bought this vehicle new and know its service life. This tpms sensor was in use for only 37 months. A 3 cent nut put my family at significant safety risk.

Valve stem broke off while low filling tire with air. Each time the tire looked a little low and when air nozzle was used it broke off and flew forcefully and all the air came suddenly rushing out. The computer low tire light was on the first time this happened, that is why I checked the pressure. I had to call service both times and had them changed tire and replace valve stem with non-computerized kind. They did not find any reasons that the tires had gone low other than the valve stem may have been already leaking. I then went to dealer to get new parts, which were still under warranty, and they said it was from misuse and wouldn't do anything about it. They were very rude. Said it was from hitting curb. It was not. The valve stem is well protected inside the rim. This has happened twice within the last six months. Both failures were nearly identical. I did not report the first time, but after checking around I found out this has happened to others and tire repairmen said they have had to change out several. Had I not seen that the tire was a little low and checked it in my garage this could have been much more devastating. I'm almost afraid to drive in case one of these would break on the road and kill me. The failures happened in December 2010 and April 2011. The vehicle I'm driving is a 2009.
Since I purchased the vehicle in April 2010, I have had to return it to the dealership 2 times (June 15-June 19, 2010 and August 2 - August 20, 2010) for the same safety issue: a defective fuel pump. These 2 occurrences have now accumulated to 24 days in total that vehicle has been out of service in the 5 month period of ownership. Date of 2nd occurrence! Friday. July 30, 2010 date of 1st occurrence; Monday. June 14, 2010 length of repair: Tuesday, June 15 - Saturday, June 19, 2010: 5 days on Monday, June 14, 2010 around 7pm, the vehicle suddenly shut down while driving on highway route 287, during my evening commute from my work location to my home. Length of repair; Monday. August 2, 2010 - August 20, 2010 - 19 days on Friday, July 30, 2010, while traveling on highway route 80, the vehicle again suddenly shut down while driving on the highway. During this incident, not only was I about 80 miles away from home, but I was traveling with 5 children in the vehicle! at this point, I became very concerned for the safety of my children in the car! the possibility that an accident could occur if my car lost power and another vehicle impacted the rear of the vehicle; or if I wasn't able to properly steer the vehicle was extremely high on such a busy highway! again, on Tuesday, September 14, 2010, the car shut off on NJ rt 78 (65 mph zone). It then continued to turn on & off during stop & go traffic. It even shut off in the credit union drive up banking window!!! since these defects substantially impair the use, value or safety of my vehicle, or the defect is one that is likely to cause death or serious bodily injury if the vehicle is driven.
