Tire Pressure Monitoring System problems of the 2010 Mazda MAZDA3

I purchased two tires from les schwab in molalla, or on 1/15/25 in which upon them changing the tires they damaged one of my tpms sensors and they did not replace it. I didn't have a warning light before I went in and now I do and they knowingly did not replace it when tpms sensor service was part of purchasing the new tires. Instead they quoted me $451. 96 to replace the sensors in all 4 tires other than replaced the one they broke. A set of tpms sensors online cost $28, this is unethical of them to take advantage of consumers like this and they should be held accountable. If I'm not mistake it says in "49 usc 30122(b)" that "prohibition. -a manufacturer, distributor, dealer, rental company, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicle safety standard prescribed under this chapter unless the manufacturer, distributor, dealer, rental company, or repair business reasonably believes the vehicle or equipment will not be used (except for testing or a similar purpose during maintenance or repair) when the device or element is inoperative.

While servicing a customer's vehicle we inflated their tires. When the air chuck clamped on the valve stem, it broke causing all air to escape from the tire, immobilizing the vehicle.

The contact owns a 2010 Mazda 3. While driving 65 mph, the rear passenger side tire exploded. The tire was replaced with a spare. The vehicle was taken to an independent mechanic. The mechanic stated that the tpms sensor was corroded and the nut was fractured. The tire was replaced and the sensor was replaced with regular valve stems. The contact also stated that the dashboard was melting, which caused a glare from the sun. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failures. The approximate failure mileage was 83,000. Updated 09/14/lj.

While adjusting the air pressure in a customer's vehicle the tire air valve/tpms sensor broke and needed to be replaced.

Within 2 days of driving, my Mazda 3 had two separate incidents, where the valves of the tire pressure monitoring system (tpms) failed, on two separate tires. On Monday, July 18, 2013 while traveling at highway speed on rt. 25 in bourne, MA, the tire pressure warning light came on. I stopped at the nearest gas station. The driver's front tire was very flat. When I attempted to fill it with air, the valve pushed into the tire. Luckily, I was at a gas station and they were able to repair the tire with "standard" (non-tpms) valve and I was on my way. As I was on vacation. I parked the car for a week. When I returned to my car (July 22), I drove the car for about 50 miles. I stopped to have lunch and noticed that the driver's side rear tire was very flat. When I attempted to put air into the valve, it too pushed into the tire. That is two tpms valves that failed in two days of driving. I called Mazda customer service (800-222-5500, ext. 6) explained the situation to jose (ext. 1180). He was sympathetic, but would not commit to Mazda repairing the tpms valve at no cost to me. I am having my mechanic put in non-tpms valves in the remaining two tires on the car, as I feel they are a real safety hazard. I will not drive the car until it is repaired. . Read more...

While checking a customer's tire pressure the tpms sensor broke causing all air to escape the tire, immobilizing the vehicle. We had a new tpms sensor installed and the tire repaired for $81. 41.

My daughter was driving the Mazda 3 headed east on I-94 in brookfield, WI near the moorland road exit on Saturday afternoon, February 9, 2013 the car was moving at about 65mph. The low tire pressure warning light came on suddenly. Then a few seconds after that the steering became wobbly and the right front tire blew. She was able to get control of the car, decelerate and pull to the shoulder. The right front tire outside sidewall was completely shredded. With the help of state trooper david w. Hanson she got the tire changed. On Monday, February 11, 2013 I took the car to a trusted mechanic. We found the tire valve and tire pressure sensor inside the shredded tire. The valve stem had blown into the tire. We didn't know what could have caused that. I had the mechanic, rob of erv's service in hartland, WI examine the other tires and valve stems on the remaining wheels of the car. He found another valve stem with a cracked housing that was ready to fail. I had the mechanic remove it and secure the valve stem. I retained the faulty parts. I believe the valve stem assembly failed causing the sudden loss of tire pressure, the shredding of the tire sidewall and near loss of control of the car. This could have resulted in a crash. Injuries and possibly loss of life.

While servicing a 2010 Mazda3 we checked the customer's tire pressure as required by law. The valve stem snapped off when an air line was attached to inflate the tire.

Tire pressure and regulating systems - I own a 2010 Mazda 3 automatic (14,542 miles) --also purchased just over a yr ago. I have now had "three" valve stems that have broken; with slow leaks and flat tires. The last one leaving me stranded for 2 hrs until help arrived. This also happened 2 days after I had my car in for service for another tire with a "valve" stem replacement--costing me $198. 00. Also told there is no recall and it appears Mazda having problems now with this for a few years. Also thought it funny that when dealership completing my papers they commented that they just completed exact same papers for car before mine !!!! I am a cautious driver and I know my wheel/tires where not damaged and that was the cause of the valve stem. I now have 3 new valves stems thru my cost ---just waiting for last one to go and then will see how long the "newer" ones last. Have a feeling this will be an ongoing problem. At least dealership changed the one today as a good will free of charge.

I own a 2010 Mazda speed 3. Purchased just over a year ago. I have a valve stem that has broken, which released pressure. The valve stems used on the vehicle are incorporated into tire pressure monitoring system (tmps), and the dealer requires that both items be replaced for $125. Aftermarket companies, such as dorman offer replacements that are modular, and allow the consumer to replace just the stem, if broken. The factory, conveniently does not offer them component individually. By the looks of online forums, this is a problem that has been around for a couple of years. I have owned vehicles for 30 years now, and I have never encountered a broken valve stem like this. There is no trauma to the wheel itself that would explain a busted stem that does not protrude beyond the rims outer edge. I believe that this dangerous problem could be eliminated if Mazda were to redesign the threaded portion of the stem to be thicker. The aluminum stems are machined so thinly, that they fail, or are easily damaged while performing basic maintenance. The Mazda dealer does not feel that the parts are faulty, and they refuse to cover this under warranty. The service manager says they have never heard of this broken stem problem. I find that extremely hard to believe. Resolution: I need to get my spare tire off the car, so I will be dropping the wheel off at a tire shop to replace the unit with a standard metal stem until I decide what route to take. My research leads me to believe that this will not be the last problem I have like this, until I get the dangerous factory ones off of my vehicle.

The contact owns a 2010 Mazda, Mazda3. While parked, the contact noticed the rear driver side tire was low on air and seemed as if the tire was flat. The vehicle was taken to a tire shop where the technicians stated the sensors were damaged and the tire was not flat. The failure also occurred to the front and rear passenger side tires. The vehicle was taken back to the tire shop where the technicians stated all three tire pressure sensors needed to be replaced. The vehicle was not repaired. The dealer was contacted and stated the repairs would not be covered by warranty because the vehicle was originally taken to the tire shop instead of the dealer. The approximate failure mileage was 32,000.

Bought a used 2010 Mazda 3 5-door in January 2013. I was driving down the highway on may 18th 2013 when I suddenly lost control of the vehicle, I cut off traffic to get into the emergency lane. Noticed that the driver side front tire was flat, put on the spare and took car to the closest tire repair shop (good year tire). Turns out that the tires tpms (tire-pressure monitoring system) sensors threads striped causing the sudden loss of air pressure in the tire. Ironically the small little sensor that is supposed to prevent running on low air pressure was at fault in this traffic incident.
