  Summary

  A New Automatic Transmission Fluid (ATF-A7) is being used for some 2023-2026 models. ATF-A7 is an extremely low viscosity formulation with low friction to achieve best-in-class fuel economy and driving performance. For easy identification, ATF-A7 is colored Red and ATF-FZ is colored Blue. There is NO interchangeability between ATF-A7 and ATF-FZ. For CX-30, Mazda3, and CX-5, some 2.5L and all 2.5T engines still use ATF-FZ. Verify the type of ATF according to what is in MGSS (TRANSMISSION/TRANSAXLE TECHNICAL DATA) or what is marked on the dipstick (see below).

  Summary

  Some vehicles may experience exterior trim heat damage such (melted, separating, etc.) when parked near a glass building or Low-E windows. This may be caused by the sun's reflection. If a structure's windows create enough of a curve, the concave glass can focus the sun's rays onto a small area and acting like magnifiying glass direct the sunbeams into a hot pinpoint of light. This magnifcation of the sun's rays can cause damage to vehicle trim (see examples). Additional information and exemplar images regarding this phenomenon can be found by performing a google search.

  Summary

  Some customers may notice water in the trunk after a car wash or heavy rain. This may be caused by insufficient sealing performance of the trunk lid weatherstrip. Due to improper installation of weatherstrips, the lip of the weatherstrip may lean toward the inside of the trunk, resulting in insufficient sealing performance.

  Summary

  Some customers may complain of an engine restart failure after i-stop activation, following a stop after low-speed driving (below 20 km/h). Engine restart is possible with key operation. This problem occurs when an IR request happens during an extremely short period (a few milliseconds) while transitioning to i-stop control, such as when the brake is released. In this case, the engine may fail to restart due to improper i-stop control. This concern has been eliminated through a PCM control software modification.
