Official summary
Some vehicles may experience an engine stall when hard accelerating from a stop (often difficult to reproduce on a test drive), no codes are stored and the vehicle easily restarts with no other drivability concerns. This is only caused in certain situations by the torque reduction calibration in the PCM software. To correct this issue, the control software of the PCM has been modified to optimize the torque reduction feature.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
