SummarySome vehicles may exihibit a vibration in the accelerator pedal and steering wheel when accelerating during a sharp left-hand turn. An abnormal noise may also be heard from the footwell area. This may be caused by insufficient clearance between the engine mount stopper rubber and the engine mount bracket. Customer may state: - Vehicle shudders/vibrates on left turns, most often when accelerating from a stop or entering a driveway. - They feel a pop or grind in the accelerator pedal when the vibration occurs. - They hear a rumbling or grinding noise, mainly from the right side, during the left-turn shudder. NOTE: The condition does not occur at shallow steering angles or when the vehicle is stationary and the steering effort remains unchanged when the vibration and noise are present.

SummaryThere are currently 2 methods for cutting a new auxiliary key blank. A. Auxiliary Key Trace Cut Method • B. Auxiliary Key Code Cut Method 2019 and newer models require a 10-digit key code to accurately cut keys • 5-digit codes CANNOT be provided for 2019 and newer vehicles (the traditional 5-digit code from the key tag or driver's door lock cylinder is not sufficient and will not be issued for key cutting on these models). • Only Mazda-approved key cutting machines can process these 10-digit codes. • Many older key machines do not support 10-digit codes and cannot be updated to do so. In these cases, dealers will need to purchase one of the newer Mazda-approved key cutting machines capable of handling this requirement. • For a list of current Mazda-approved machines and purchasing options, refer to the Mazda Dealer Equipment Program or view the current Mazda approved key machines below.

SummarySome vehicles may exhibit a key-in lock situation when the speed-sensitive door lock activates unexpectedly while idling in the P-range. This may be caused by the noise generated by the Anti-lock Braking System (ABS) wheel speed sensor being mistakenly recognized as a vehicle speed pulse. To eliminate this concern, the IC chip in the ABS wheel speed sensor has been modified.

SummaryThere are wrinkles on the leather seat cushion and/or seat back surface at PDI, when new vehicle is delivered, or when new upholstery is installed under Warranty repair. NOTE: This repair is not a permanent fix, it is meant to make new seats look their best when the vehicle is first presented to the customer. Wrinkles may not be completely removed after the repair is completed. Leather is a natural material and may develop some wrinkles due to aging and wear during normal usage.

SummaryThe 7G large platform utilizes a new 8-speed automatic transmission. Due to changes in the parking lock mechanism, which is now hydraulically operated, the neutral range in the transmission can only be achieved if the engine is running (or “Ready-On” for PHEV). With this design, there is no provision to manually engage neutral. This can cause challenges to dealers, customers, or towing providers when a vehicle cannot start and can't move, usually due to a discharged (dead) battery. In the event that a vehicle cannot be started or achieve “ready-on”, wheel dollies must be used to allow the vehicle to be rolled and moved. NOTE: The following procedure is for moving vehicle around the service shop and not for towing purposes. Please reference the owner's manual for towing instructions.
