What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 6 years — the issue may be aging out of the active population.
What owners are reporting 2 most recent
Both rear tire pressure sensors failed due to either over-tightening or corrosion. Both sensors snapped off right below the sensor stem cap causing both rear tires to deflate. On a newer car still under warranty, Mazda claims sensors are only covered until 36000 miles. And they're not cheap either ($80 each, not including installation.) *tr
