What's wrong?
In recall 19V497, the powertrain control module on certain 2018-2019 Mazda CX-5, MAZDA6, and MAZDA3 vehicles is the engine computer. It controls engine functions, including the hydraulic valve clearance adjuster, which uses oil pressure to keep valve parts moving in the right position.
The problem is in the software that controls that oil-pressure action during the change from cylinder deactivation back to full cylinder operation. If the control signal is wrong, an intake valve rocker arm can move out of position and contact internal engine parts. That can lead to rough running, an engine misfire, loss of power, a check engine light, or an engine stall.
There is no warning sign before failure. The first thing an owner notices can be lack of power, an engine stall, or the Malfunction Indicator Light, also called the check engine light.

What should I do?
- Check your VIN to confirm your 2018-2019 Mazda CX-5, MAZDA6, or MAZDA3 is included in this recall.
- Contact a franchised Mazda dealer to schedule the free PCM software reprogramming that fixes the engine stall software error.
- Bring the recall notice if Mazda mailed one. If not, reference recall number 19V497 and Mazda recall 3719F when you call.

What happens at the repair
At the dealer, a Mazda technician reprograms the Powertrain Control Module software that controls engine operation. The recall repair is free, with parts and labor covered by Mazda. If you already paid out of pocket for a repair tied to this PCM software issue, Mazda's standard reimbursement plan covers documented expenses. Bring the repair paperwork and payment records to the service desk so the dealer can tell you how the claim is handled.
