Safety Recall: 2021 RDX Left Side Front Driveshaft
AFFECTED VEHICLES
| Year | Model | Trim | VIN Range |
| 2021 | RDX | ALL | Check the iN VIN status for eligibility. |
BACKGROUND
A small number of 2021 RDXs were manufactured with left side front driveshafts that have constant velocity joints (CV Joint) which were improperly manufactured. If the complete driveshaft is not replaced it could result in premature wear, excessive noise, vibration, and over time possible part failure. The affected vehicles will only have a left side front driveshaft that will need to be replaced. No vehicles will require both front drive shafts to be replaced. The VIN inquiry system will identify which vehicle needs the left side front driveshaft to be replaced.
CLIENT NOTIFICATION
Owners of affected vehicles will be sent a notification of this campaign.
Do an iN VIN status inquiry to make sure the vehicle is shown as eligible.
Some vehicles affected by this campaign may be in your new or used vehicle inventory.
Failure to repair a vehicle subject to a recall or campaign may subject your dealership to claims or lawsuits from the client or anyone else harmed as a result of such failure. To see if a vehicle in inventory is affected by this safety recall, do a VIN status inquiry before selling it.
CORRECTIVE ACTION
Replace the left side front driveshaft.
