Xxxxx Problems of Mazda MAZDA3

Mazda3 factory-installed tire inflation valve stems are prematurely failing resulting in an immediate tire deflation with no prior warning or indication of failure. Failures have occurred when the car was parked and when moving. There was no prior indication (I. E. No warning or slow loss of pressure) of a problem with the valve. Prior to this vehicle, I have never had a tire inflation valve stem fail in the 35+ years I have owned vehicles. However, this has happened three times to this specific vehicle (which we purchased in 2014) with the most recent occurrence happening today, 16 Jan 2019. A quick internet search revealed this is a wide-spread problem with Mazda 3 tire inflation valve stems. I've attached pictures of today's failure as well as an exemplar website printout of identical complaints by other Mazda owners. Given the unwarned and rapid failure of these valve stems, this is an immediate safety hazard due to the potential loss of control should the tire inflation valve stem fail at highway speeds, especially during adverse weather.

Was traveling at highway speeds on the bypass when the valve stem and tpms sensor broke off and immediately deflated the tire shaking the vehicle violently and almost causing driver to lose control. Have brought this complaint to Mazda in the past and they said they know that it is caused by using dissimilar metals on the tpms sensor causing erosion to the stem and ultimately the stem breaking off. This tpms sensor was already replaced on the vehicle at the tire change interval and still failed long before the vehicle was due for another set of tires. Mazda knows these are defective and refuses to do anything about it. I'd rather not have tpms and not know what my tire pressures are than to have that system endanger myself or my family any more. It is currently more dangerous to use these defective faulty tpms sensors than it is to not have them. That should tell you something. . .

Tpms/valve stem assembly failed suddenly causing an immediate lost of air in the tire on 2-lane marked highway(posted speed limit 55mph).

Twice now, when I was alerted via my tpms that I had low tire pressure in one of my tires, I stopped at a service station to add air to my low pressure tire. As I applied the air hose to the valve stem, the valve stem (and the attached tpms sensor, disappeared into the wheel and tire and the tire went immediately flat. . I believe this to be the result of faulty design of the tpms assembly. The materials used in the collar and nut that secure the tpms assembly to the wheel is not appropriate for the environment (exposed to road salt, dirt, grime, brake dust, etc. ) in which the tpms assembly must function. The collar and nut corrode and eventually fail due to that exposure. Fortunately for me, I was stopped at the time of those failures; had I been traveling at highway speeds the complete failure (no air pressure remaining in tire) could have been catastrophic. The first assembly failed at approximately 36,500 miles and this most recent one failed at 61,800 miles. Both tpms assemblies were oem parts and were installed on the vehicle when we bought the car new from Mazda. I have seen many reports online describing similar failures. To the best of my knowledge, Mazda has not yet recognized or acknowledged this as a problem with the design and failure of their tpms assemblies. I would like them to acknowledge the problem and take action to address their faulty design, before someone gets hurt or dies from an accident resulting from another tpms assembly failure.

At 78,000 miles one of my valve stems failed while driving at 65 mph. When I inspected the other three wheels, based on a recommendation from shop, I found another stem with about 2/3 of the nut missing along the entire length of the stem shaft. See pictures. If the front wheel stem had failed rather than the back wheel stem I could have had serious control issues.

Tire pressure sensors defective. I have had to replace all 4 of the sensors because of broken retaining nuts or corroded stems. 3 of the sensors failed during driving, causing an immediate loss of tire pressure, causing me to also replace 3 of my tires. Another failed as I was checking the tire pressure, falling into the tire. Per goodyear tire stores, other manufactures have gone to a replaceable rubber stem because of this, but not Mazda. First sensor replaced at Mazda dealership approximately mid 2011, second sensor replaced 6/01/2013, third sensor replaced 9/17/2014, and fourth sensor replaced 3/12/2016 all by goodyear tire stores.

Tire pressure sensors corrode and fall apart causing tires to go flat instantly. I have had 3 of the original sensors fail and the most recent one (2-16-16) also destroyed the tire. This happened to my wife on 2-16-16. These original sensors are a safety hazard and should be recalled.

[I bought my car used, and it came with the tpms light on. I was told it was because the passenger rear sensor wasn't transmitting. I check my tire pressure often, and ignore the tpms light because those sensors are expensive! more on this later. ] as I was accelerating from a stop light a few weeks ago, I realized I was getting a flat tire on the driver front. I pulled over and, as I was taking the lug nuts off, noticed the valve stem had disappeared. After I got to the tire shop and they were inspecting the tire, the tech informed me the flat was because the entire valve had fallen out of the tire! they also informed me the passenger rear tire did not have a faulty sensor; the valve had been replaced (by the previous owner) with a non-sensor valve. I found it strange that now two tire valves had been replaced on my car. When I researched this online, I discovered my model year has several complaints of the valves breaking or falling out! and now my driver rear tire is losing air, so I suspect that valve needs replaced, as well. I contacted Mazda and was surprised to find their email response included no mention at all of the tire valves - the entire point of my contacting them. I found other owners online stating Mazda is aware of this problem, but refuses to issue a recall. At this point, I have one replaced valve without a sensor (courtesy of the previous owner), the $80 valve I just replaced (with a sensor), one valve I suspect is leaking and needs replacedn, and one valve that may fail at any time like the one a few weeks ago. Mazda needs to address this and rectify it. They're lucky that valve failed before my road trip on the 9th, when I would have been going 70 mph on the highway! and I don't appreciate having to spend $320 to correct Mazda's mistakes.

Four new tires installed last summer. Since then two have failed while driving. The first time I thought my daughter hit something when the right front totally failed (replaced new tire under 5000 miles). She said it happened while driving slow thru neighborhood. Then the left front failed a few months later and she had it replaced. She was told the problem is the tpms, and that the right rear will probably fail too.

While driving on the highway I heard a loud clatter like a rock in the wheel well and the saw something bounce out from the side of my car. Moments later the car began to shake and veer to the left. I was able to move over and pull of to the side of the highway to find that my valve stem on my wheel had lost the nut holding it in place so that the valve fell into the tire leaving a large hole. After having the tire replaced (it was destroyed) I saw that the valve (which was part of the tpms) was corroded and could be easily snapped in half. Another of these valves had failed four months prior so I think this is a common problem. Mazda refuses to believe there is anything wrong with their part and suggests that I continue to drive with the remaining sensors.

The tire valve stem cracked while checking air pressure on one of the tires. After that the other stems looked like they were ready to fail. Had them all replaced.

While driving on the highway my tire pressure monitor system (tpms) light came on to indicate a low tire. I pulled into the gas station near my house right after and check my tire pressures. When checking the driver side rear tire pressure with a tire pressure gauge the tpms sensor and stem pushed in and air blasted out, blowing several pieces of the sleeve that keeps the stem in place off of the wheel/stem. I picked up the 2 remaining pieces (one third of the sleeve was missing and presumed to have fallen off while driving) and they had cracked lengh-wise and had a large amount of white corrosion in the threads. The remaining stem was also covered in white corrosion on the threads and the tire had lost most of its pressure. I still have those pieces of the cracked tpms sensor sleeve if needed to be examined. I took the vehicle and wheel to the Mazda dealership where they inspected that wheel as well as the others. They stated that 2 of my other tpms sensors had cracked sleeves that could come off at any time in addition the the one that had failed. If one of those had failed on one of my front wheels this could have caused a loss of control while driving.

On August 16th 2013 I was on the highway and the tire pressure warning came on and a few miles later felt the car pulling towards the left and realized I had a flat tired and pulled over. I changed the front drivers side tire and continued on my way. The next day I took it to a local mechanic shop and requested they look at the tire. They informed me the tire was perfectly fine and what caused the tire to go flat was the tpms sensor. The sensor threads had corroded and released all of the air from the tire. They then informed me all of the remaining sensors were in just as bad shape and could fail at literally any moment. I then took the vehicle back to the dealership. The dealership looked the vehicle and confirmed that tpms sensor was what caused the tire to go flat and the other sensors are bad and ready to fail as well. I had three sensors replaced and I went home and decided to call Mazda directly and speak with a representative and see what could be worked out. I spoke to a representative by the name of ann and I asked if there was any recall on the vehicles tpms sensor. She informed me that there was not a recall on the item I specified and that it was going to be documented. That was it. Basically I was told good luck with my problem. I went back to the dealership and had them replace the final tpms sensor since it was going to fail soon and I didn't want another flat tire or worse, an accident. I've looked around the internet and found other people complaining of the same issue on Mazda vehicles in a very close year range as mine. I feel this is a huge safety issue. It is not normal for an item of a vehicle to fail and release all of the air from the tire if the item wasn't damaged by some sort of external force.

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...

Only owner of a 2010 Mazda 3. Issues with car since purchasing. Replaced tires in winter of 2012, few weeks later tire pressure light came on. Filled tires with air. Few weeks later, same occurence. Brought car to the place were the tires were professionally installed. The inspected over all 4 tires and found that 2 of the 4 tire stems needed to be replaced. Called Mazda corp and they stated the car needed to go to a dealership to be diagnosed. ( for leaking tire stems ). Called my local Mazda where the car was purchased, they were great and said they wouldnt charge a fee to diagnose leaking stems as it was obvious. They did find that 2 of the 4 were broken. 1 was actually snapped in half. No driver error noted, or damage to rim. If you google this issue there are other complaints out there regarding this, but Mazda still wont recognize this as a safety issue. My question being. . . What if the stems failed at a high rate of speed ????.

I was driving on the highway traveling about 65 mph when my tire warning light came on, followed immediately by my front driver's side tire going completely flat. Luckily there was nobody too close to me, so there was no accident when I swerved onto the shoulder of the road. I changed my tire and made it to a service center where I was informed that it was my tpms and valve stem assembly that had corroded and failed, causing my tire to immediately go flat. Not only did I have to pay to install a new tire ($300) I had to replace the destroyed tpms sensor and replace another one that was also corroding. ($100 ea). The entire incident cost me about $500 due to a design flaw from Mazda that I have no power to avoid. The issue is that it is illegal to remove or not have the sensors re-installed, as they are a safety feature. The irony is that I have to pay $100 each to install a component that causes one of my tires to immediately deflate randomly in the next 3-5 years, depending on when it corrodes again. It is infuriating that I have to install a "safety feature" that will randomly cause me to lose control over my car in the near future. As it is right now, I will be forced to drive with a component that, over time, will corrode and fail, causing me to lose control of my car, then re-install the exact faulty component. The sensor / valve assembly should have never been made of a material that is susceptible to corrosion in the first place. I was lucky this time that this didn't cause an accident, but if the situation were different I could have easily been killed or have killed someone. This is a serious issue that needs to be addressed. Both Mazda and the government have been aware of this issue for a long time now. What is going to happen when someone does die from this, and it comes out that the issue has been known for years, but nobody did anything?.

Tire pressure monitoring system sensor failed causing the tire to blowout and go flat on the highway. The stem of the sensor was corroded which caused the incident.

Checking tire pressure in driveway and tpms sensor - tire valve cracked and failed in 3 of 4 tires/wheels. Two today, and the first approx. 3 months ago. Imagine what could happen if one of these valves failed while driving down the highway.

The contact owns a 2010 Mazda Mazda3. The contact stated that the rear tire pressure sensors failed. The vehicle was taken to a dealer and it was found that the inside of the valve stems had rusted. The dealer determined that the valve stem needed to be replaced with a rubber stem instead of a metal one to prevent rust. The vehicle had not been repaired. The failure mileage was not available. The current mileage was 27,000.

The contact owns a 2009 Mazda Mazda 3. The contact stated that while driving 55 mph, the tpms failed and the tire went flat. The vehicle tire was changed. The vehicle was taken to a dealer for inspection and they stated that the valve stem needed to be replaced. The vehicle was repaired but the failure recurred. The manufacturer was notified of the failure. The failure mileage was 38,000.
