What’s wrong with it?

If a vehicle downshifts unexpectedly, the driver may lose control of the vehicle, increasing the risk of crash.

Aisin World Corp. of America (Aisin AW) is recalling certain Transmission Control Modules (TCM), part numbers PSPD189E1, PEFB189E1B, PAC6189E1A, PEFB189E1A, PEFB189E1C, 50052911, PEFB189E1D, 50053305, and 50054938 sold for use in 2016-2019 Mazda Miata MX-5 and 2017-2019 Fiat 124 vehicles equipped 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.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
  • How many have been returned or fixed isn’t in the notice.
