Mazda e-Skyactiv D 3.3 seis cilindros microhíbrido (T3-VPTS)Electronics
Stalling and restart failures due to control unit software on the e-Skyactiv D 3.3
Why this rating?
High severity: Risk of a serious engine, turbo or gearbox failure.
Frequency occasional: These are preventive campaigns with a software fix; no source quantifies how many cars suffered the symptom. In the UK, for example, the DVSA counts 758 cars in AR056A, 429 in AP049A and 3,067 in AP047A. On the guide's scale, a preventive campaign with a definitive fix is "occasional".[1][2]
Symptoms
- The engine may stall at idle or fail to restart after an i-stop shutdown, even when the accelerator is pressed, according to the DVSA and Safety Gate.[1][2]Engine stalls: other faults that cause it · As soon as possible
- The engine and electric motor may go into limp mode with little or no prior warning (DVSA campaign AP047A).[1]Limp mode: other faults that cause it · Garage soon
Why it happens
Incorrect software programming in several control units (engine control PCM, battery management BECM, transmission TCM and the instrument cluster power supply unit, Dash-ESU) according to Safety Gate; in the older British campaigns the PCM or the DC-AC inverter of the mild-hybrid system is reprogrammed.[1][2]
If it is not repaired: A stall or start failure while driving increases the risk of an accident; Safety Gate classes AR056A as a serious alert.[2]
Affected cars and years
AR056A affects CX-60 cars with "T3 M Hybrid Boost" (the 3.3 diesel) built between 28/09/2022 and 23/07/2024 (Safety Gate SR/01913/25). The British campaigns AP014A, AP047A and AP049A are listed for the CX-60 without distinguishing the powertrain, with production between September 2022 and July 2023, so we cannot be sure which ones include the diesel.[1][2]

What owners say
Frequently asked questions
Is it a fault of the 3.3 diesel engine?
According to the sources it is a control unit software fault, not a mechanical defect of the inline-six; the remedy is reprogramming at the official dealer.[1][2]
How do I know if my CX-60 is in the campaign?
Give the VIN to an official Mazda dealer: they will tell you which campaigns affect your car and whether they have already been carried out.[2]
Can I keep using the car?
The campaigns themselves point to a risk of accident if the engine stalls while driving, so it is best to visit the official dealer as soon as possible.[2]
