What's wrong?
The front driveshaft on affected 2021-2022 Acura Rdx and Cr-V Hybrid vehicles carries turning force from the powertrain to the front wheels. Its outboard joint sits near the wheel and lets the shaft keep spinning while the suspension moves and the wheels steer. That joint depends on hardened steel balls that roll smoothly under load.
In these vehicles, a component inside the right or left front driveshaft was not heat-treated correctly. The steel balls inside the outboard joint were not hardened to specification. As the driveshaft heats and turns during use, those balls can deform, wear faster than designed, and cause the outboard joint to seize. Once that happens, the driveshaft can fail.
There is no warning sign before failure. An owner should not rely on noise, vibration, or a dashboard light to tell them the front driveshaft is damaged.

What's the safety risk?
A front driveshaft failure can cut drive power without notice. It also can let the vehicle roll away after parking when the parking brake is not applied, increasing the risk of a crash or injury. Use the parking brake every time you park and schedule the repair soon. Repair is free at any franchised Acura dealer.
