Service bulletin A21-047
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| PUD - 2016-20 HR | 2022-05-06. Service bulletin. "Customer letter - Our records indicate that a PRODUCT UPDATE has not been completed on this vehicle. The current continuously variable transmission (CVT) software does not properly monitor internal fluid pressure and detect early CVT belt failure. This can possibly cause the vehicle not to move when accelerating. Honda is providing a product update with new CVT software to fix this issue." |

Service Bulletin - Due to the possibility of early deterioration of the Continuous Variable Transmission (CVT) drive belt, American Honda is extending the warranty coverage on these CVT models to 7 years from the original date of purchase or 150,000 miles, whichever comes first. If the PCM software was previously updated in service bulletin 21-046, Product Update: 2016-20 HR-V Software Update and CVT Inspection, the warranty extension applies, since the CVT primary drive belt is now a OBD-monitored part due to the addition of DTC P271E. |

| A21-046 | 2021-08-17. Service bulletin. "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." |
