WASHINGTON, DC (February 1, 2019) – Mazda North American Operations has filed a Defect and Non-Compliance Information Report with NHTSA regarding a safety concern with certain Model Year (MY) 2016-2019 Mazda MX-5 Miatas. In affected vehicles equipped with automatic transmissions, electrical noise in the range signal may be detected while driving in “D” range (including “Manual” mode). Due to inappropriate control logic of the clutch control software in the Transmission Control Module (TCM), this signal noise may cause the vehicle to unexpectedly downshift, causing an abrupt deceleration of the drive wheels.
A sudden decrease in the speed of the drive wheels while driving may negatively affect the directional stability of the vehicle, increasing the risk of a loss of vehicle control and potentially resulting in a crash.
Approximately 14,370 vehicles are affected.
There have been no reports of accidents or injuries.
Mazda North American Operations is headquartered in Irvine, California, and oversees the sales, marketing, parts and customer service support of Mazda vehicles in the United States and Mexico through nearly 700 dealers. Operations in Mexico are managed by Mazda Motor de Mexico in Mexico City.
