2009 Mazda MAZDA3: tire blowout or tread separation

Filed Sep 7, 2013 · 74,904 miles · KY

Three out of four tire pressure monitors have failed causing tire deflation. The first two times this was discovered in my driveway.upon trying to re-inflate the low tires I found that the tire pressure monitors just fell away into the interior of the tire. My tire dealer was able to reinstall the monitors(only to have them fail again later) my complaint stems from the incident (after I have stewed about it for a while) that happened on 6-26-2013. My wife,with daughter, had a blowout on interstate 75 at rush hour in a driving rain storm. Of course it was a harrowing experience getting the vehicle to the shoulder. Luckily a less experienced driver was not at the wheel. When I arrived to change the tire I decided to try and re-inflate it first to try and get to a safer location. Once again the tire pressure monitor fell to the interior of the tire!!! My tire dealer (tire discounters walton ky) told me that the threads on the stem that holds the monitor to the wheel corrodes and eventually cracks the nut holding the monitor. What a piece of junk. I still have the old monitors and indeed the corrosion looks like something that comes from a dissimilar metal on metal contact. This is a major safety concern in my opinion and I should have complained as soon as I could but I really think that nothing will come of it. I almost paid for new monitors(decided to just replace with plain stems on my own as I do not trust ,nor do I want to finance mazda any further), I lost a tire due to the highway incident and I found out that this is no surprise to the tire store.

12/26/12, tire pressure light came on, pulled off highway immediately, tire flat, nut holding pressure stem had disintegrated and stem went inside tire. 1/2/13, another tire went flat in parking area, neighbor came over to put air in tire, nut holding pressure stem had disintegrated and stem went inside tire. Mazda dealership made repair and said the other two tire stem nuts would go in about two weeks. All four tire stem nuts were replaced. Research on internet shows that this same problem has occured to many people owning different make/model/year vehicles. Apparently a defective nut and stem system with one of three serial numbers were on all the vehicles experiencing this dangerous situation. I believe these nut and stem systems with these serial numbers should be recalled as soon as possible as to avoid anyone experiencing a dangerous blowout. A nut on the wheel should not be made of a material that disintegrates in less than 4 years even if it is in contact with road salt. This is very dangerous. The fact that two nuts disintegrated in 8 days and probability of next two in two weeks should raise red flags immediately. This should not happen to anyone! I am submitting this information for my daughter as she is still very upset over this having happened and having incurred great expense on her part.

Tpms valves badly corroded and leaking air, these need to be recalled and replaced by mazda due to thousands of complaints about this occurring under normal use and care. This is definitely a major safety issue because of possible blowouts at highway speeds.

Purchased my 2009 mazda in january, 2009. I had to replace the tires 7/ 30/10 because they were almost bald. They didn't even have 16,000 miles on them! Less than 16,000 miles in 18 months shows I'm not a hot rodder who abused my tires. I had them rotated at least once during the time I had them; I don't think lack in rotating the tires would cause all four tires to go bald! Good thing I noticed it before I got a blow out. Even if they are specialty/performance tires, to need replacement of tires before 16,000 miles is ridiculous! This is my 4th mazda and I must say I am disappointed at the quality of tires they have on a new vehicle, less than 16,000 is not acceptable. I now have new tires which have 10,000 miles on them and you can hardly tell they have been used. Cost me $650!

Tl* the contact owns a 2009 mazda mazda 3. While driving approximately 60 MPH, the front passenger side tire blew. The contact inspected the failure and discovered that the front passenger valve stem casting was disintegrated. Also, the rear passenger side valve stem casting was cracked. The vehicle was driven to an independent mechanic where the front passenger side tire sensor and valve stem were removed. The mechanic replaced the valve stem with a standard valve stem yet the sensor was not replaced. The vehicle was later taken to a second independent mechanic to repair the cracked tire valve stem on the rear passenger side. The vehicle was repaired. The contact was concerned that the front and rear driver side valves would experience the same failure. The manufacturer stated that the repairs for those valves would not be covered under warranty because the valves had not failed. The approximate failure mileage was 45,000. Updated 08/31/11

Had my mazda 3 oil changed today and found out that it needed new tires - at just under 15,600 miles. I had these tires rotated at just under 6,000 miles and just under 12,000 miles. The defect is due to the alignment set at the factory, that causes the rear tires to "tilt in at the top" to improve handling. I am having to pay for (4) new tires and paying an extra charge to get the alignment set correctly. I will never buy another mazda product. If this defect at not been found today, the way the rear tires looked, I possibly could have had a blowout over the next 3,000 to 5,000 miles.
