19V072000 · Power Train:Automatic Transmission:Control Module (Tcm/Pcm/Tecm)
Reported: 2019-02-01 (February 1, 2019) · Model years: 2019
Mazda North American Operations (Mazda) is recalling certain 2016-2019 MX-5 (Miata) vehicles with automatic transmissions. Due to incorrect programming of the Transmission Control Module (TCM), certain conditions may cause the vehicle to unexpectedly downshift and abruptly decelerate.
Consequence: If the vehicle abruptly downshifts, the driver may lose control of the vehicle, increasing the risk of a crash.
Remedy: Mazda will notify owners, and dealers will reprogram the TCM with corrected software, free of charge. The recall began March 14, 2019. Owners may contact Mazda customer service at 1-800-222-5500, option 4. Mazda's number for this recall is 3019A.

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
