Recall 19V424 affects 49,898 2016-2019 Acura Ilx vehicles for driveshaft separation that can cause loss of drive. Repair is free at any franchised Acura dealer.
Acura is recalling 49,898 2016-2019 Ilx vehicles because excessive grease can keep the set-ring on the half shaft from fully engaging, and the driveshaft can separate from the half shaft. A separated driveshaft can cause loss of drive or let the vehicle move while in Park, which raises the risk of a crash or injury, and the Acura dealer repair is free.

What's wrong?
The right driveshaft on the 2016-2019 Acura Ilx is part of the driveline that carries engine power from the transmission side to the wheel side. A set-ring is a small retaining ring that helps lock the driveshaft into the half shaft, so the connection stays seated while the suspension moves and the wheels turn.
On affected vehicles, too much grease was applied to the right driveshaft during production. That extra grease can keep the set-ring from fully engaging. When the ring does not lock into place, the driveshaft can separate from the half shaft. If that happens, the vehicle loses motive power because the driveline connection is no longer transferring power to the wheel.
There is no warning sign before failure. The problem is inside the driveshaft connection, so an owner is not given a sound, light, vibration, or pedal change that confirms the set-ring has not seated.

What happens at the repair
At the dealer, an Acura technician inspects the driveshaft and half shaft connection and checks whether the set-ring is fully engaged. If the parts are not seated correctly, the technician replaces the driveshaft, the half shaft, or both. The recall repair is free, and parts and labor are covered. If you've already paid for a related driveshaft or half shaft repair before the recall notice, Acura's standard reimbursement plan applies to documented expenses. Ask Acura customer service or the service desk what paperwork they need.
