Safety Recall: 2016-19 ILX Driveshaft Inspection
Supersedes 19-035, dated June 7, 2019. See REVISION SUMMARY.
AFFECTED VEHICLES
| Year | Model | Trim | VIN Range |
| 2016-19 | ILX | ALL | Check the iN VIN status for eligibility. |
REVISION SUMMARY
Under INSPECTION PROCEDURE, several images were updated.
BACKGROUND
The right driveshaft may not have been properly assembled and installed, and may separate from the intermediate shaft. If this happens, it will cause a loss of power transfer to the wheels, leading to the vehicle coming to a stop. On a parked vehicle without the parking brake applied, this will allow the vehicle to move.
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
Inspect the right driveshaft installation on the intermediate shaft. If the installation is incomplete, or the driveshaft is not fully set to the intermediate shaft, replace both shafts.
