## What is wrong

Honda \(American Honda Motor Co.\) is recalling certain 2021 Acura RDX and 2022 CR\-V Hybrid vehicles.  A component in the right or left front driveshaft may have been improperly heat\-treated, which could result in driveshaft failure.


## What can happen

Driveshaft failure can cause a sudden loss of drive power, or cause the vehicle to roll away when parked if the parking brake is not applied.  Either condition can increase the risk of a crash or injury.


## The remedy

Dealers will replace the right or left front driveshaft as necessary, free of charge.  Owner notification letters were mailed January 24, 2022.  Owners may contact Honda customer service 1\-888\-234\-2138.  Honda's numbers for this recall are BBY, NBW, and OBX.
