- [A21\-046](/bulletins/10200408.md), 2021-08-17, Service bulletin: ENGINE AND ENGINE COOLING; POWER TRAIN. "Service Bulletin \- An incorrect value in the PCM may cause a pressure problem in the CVT under certain driving conditions, causing increased surface pressure on the belt leading to a partial or complete breakage as well as possible ring breakage. New PCM software will increase the overall durability of the CVT primary belt within the transmission. This is accomplished by revising operational loads placed on the belt under certain driving conditions. DTC P271E is added so at the early stages of a CVT primary belt failure, the D light will flash, the MIL will come on, and engine power output will be reduced. This will lessen the chances of an unexpected, sudden loss of acceleration and allow the customer an opportunity to get the vehicle to a Honda dealer."
