Customers may also comment on one or more of the following: ● K0 Adaptation routine runs when vehicle stationary and EV Mode. ● Vehicle loses propulsion capability. ● Service transmission warning indicator is on. NOTE: Require key cycle to recover. ● Shifts rough occasionally when coming down to a stop. ● Shifts rough occasionally when accelerating. ● Shifts rough when transitioning from EV to Hybrid operation on low SoC. ● Shifts rough when engines starts. ● On part throttle accelerations with little to no battery available the transition from battery power to engine on is harsh and abrupt. ● The engine oil life on dashboard drops down too fast when the engine oil dilution reaches high level without the ability to recover. This bulletin involves reprogramming the TCM with the latest available software."

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
