  Summary

  A tapping/rattling noise may be noticed from the valve train area. This operating condition can occur on new vehicles which have been delivered to Mazda dealers (due to loading and unloading from transport trucks or customers moving their vehicles in and out of their garages to wash the vehicle, etc.). This condition may also occur if the engine is not allowed to warm up after multiple cold starts.

  Summary

  Some vehicles may exhibit wiper blade contact with the A-pillar trim, with or without a chattering noise. This condition may be caused by worn or contaminated wiper blades. It can also be caused by bent wiper arms, or loose wiper arm retaining nuts due to improper handling. Improper handling occurs when pulling on or forcing the wiper arms. Technicians should be aware that while replacement of the wiper blade may resolve some cases, correction of bent components or repositioning of the wiper arms, particularly when the retaining nut is loose, requires additional steps to ensure proper alignment and function.

  Summary

  A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. “Mazda Air Cooling Coil Coating” is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years.

  Summary

  Some customers may complain of a squeaking noise from the driver side seat back. The noise may be due to rubbing between the lumbar part of the driver’s seat back (1) and the rear console lid. The lumbar support pad may be deformed outward and may rub against the rear console lid while driving or when adjusting the seat memory. This can cause a squeaking noise.

  Summary

  The new AWD rear differential DOES NOT come with a breather cap on the rear of the differential, therefore a new one will need to be ordered and installed when replacing the differential. NOTE: The breather threads have a sealant and locking compound that prevents it from being reused. Refer to GEPC for the correct part number of the Differential Breather. The instructions on MGSS will be updated soon to include replacing the breather when replacing the differential with a new unit.

  Some vehicles may experience a sunvisor that does not stay in the fully retracted position (as shown below). The left and/or right side sunvisor may lower slightly due to its own weight. The part where the sunvisor connects is broken, so the spring cannot hold the sunvisor in the fully retracted position.
