The contact owns a 2010 Mazda Mazda3. The contact stated that while driving 65 mph, the tire pressure warning lamp illuminated and after inspecting the left rear tire, the contact noticed that the sleeve for the tire pressure sensor was corroded. The contact also noticed that both of the rear and the passenger side tire pressure sensor sleeves had developed cracks. The vehicle was taken to the dealer. The technician verified that the sensors were defective and corroded the inside of the tire. As a result, all four sensors and one of the tires needed to be replaced. The manufacturer was not made aware of the failure. The vehicle was repaired. The failure and current mileage was 58,000.

Tire pressure warning light came on, so I checked the pressure of each tire. One was low, so I asked my mechanic to fix it. He found the leak was a cracked valve stem assembly, allowing air to escape along the valve stem. Fortunately it didn't damage the new tire, but still cost $150 to fix and I found this to be a common complaint for the Mazda3. For me, the safety issue is having this problem happen when my wife is driving this car on a trip, sees the warning light come on, and has to find help to fix it or to change the tire for the spare, or the leak becomes fast enough to give her a flat tire.

New car, Mazda M3, purchased in April 2010. Yokohama tires were on the car. Car currently has approximately 18,000 miles and tires have been rotated. Last night while traveling approximately 40mph, the rear passenger tire went flat. Upon removing the tire to fix the flat, the sidewall had split from the tread. This happened on the inside of the tire meaning the side of the tire against the car so it was not visible from just looking at the outside of the tire. The split is 15 inches in length and I can see that there are other areas that look like they are about to split as well. I found NHTSA campaign id number: 12T025000 talking about recall of a yokohama tire that seems to match what I have had. I have contacted my car dealer as the recall says the dealer will replace free of charge, but they aren't aware of any recall. I've been on hold for yokohama for 30+ minutes with no luck in speaking to a live person. I can't afford not to have a car and based on all I've read about these tires, I can't afford to have my children ride on tires that perform like this. I can't afford to wait on a process to determine if yokohama will make good on their warranty claims. I have to purchase new tires and will be purchasing 4 new tires and not yokohama.

The valve stem of my tire pressure monitoring system (TPMS) had significant corrosion leading to immediate and rapid deflation of front left tire while removing air hose while tending to TPMS warning light. The rapid deflation was due to complete and immediate severance where the threaded portion of valve stem met valve cap without any torque or abnormal pressure applied. The severed edge of the valve stem shows clear evidence of corrosion 360 degrees and inward, with a thin halo (appx. 1/10 of the wall) remaining. Both the tire and valve stem showed no sign of leaking and held proper pressure while filling to recommended pressure until removal of air hose caused the stem to split horizontally between the 9th and 10th thread. Plastic valve caps were in place on all 4 tires. Spare tire also not able to be put in place due to 'stuck' lug nuts on same tire; similar corrosion is suspect, possibly caused by galvanic corrosion due to metals found in disk brakes, shoes or alloy rim. Vehicle is still under warranty and needed tow to nearest Mazda dealership for repair. When calling the service department about sending my vehicle over I addressed my concerns about the other 3 valve stems needing replacement and was told "they are $150 each so if you want to pay to have the other ones replaced you can, but the dealership isn't going to pay for it" my response: "really" I'm thankful this didn't happen on the highway, I would hope the safety of your customers would come first"..no im sorry, no we'll look into it for you, just "well can I give you the number for roadside assistance""

2010 Mazda 3 excessive tire wear. Bought car new in Oct 2009. May 7th 2010 the car has 18,000 miles on it and the rear tires are down to the steel belts. My net searching shows this is a very common problem. How a car can have only 18,000 miles on it and have dangerously worn tires is beyond belief. The dealership considers this "normal on Mazda 3's". tires were well maintained with tire pressure by me. My car has never been in an accident or hit a significant road hazard. Car is used for mostly straight line highway driving.
