Recall 16V156 affects 75 2016-2017 Mack Titan (Td) trucks for steering shaft separation. Do not drive. Free interim repair is available at franchised Mack dealers.
Separation of the steering shaft results in complete loss of steering and can lead to a crash. Do not drive the truck, even for short trips, until Mack's interim repair is applied. If it has to move, call the dealer and ask about towing. Repair will be free at any franchised Mack dealer once Mack opens it.
Mack is recalling 75 2016-2017 Titan (Td) trucks under recall 16V156 because the bolt connecting the upper and lower steering shafts can fail to secure the shaft, allowing the steering shaft to separate. Do not drive these trucks; separation causes complete loss of steering and raises crash risk, and the Mack dealer repair will be free once Mack opens it.

What's wrong?
The steering shaft on the 2016-2017 Mack Titan (Td) is the mechanical link between the steering wheel and the steering gear farther down the column. When the driver turns the wheel, the upper steering shaft transfers that motion through the lower steering shaft so the truck responds in the intended direction.
On affected Titan (Td) trucks, the bolt that connects the upper steering shaft to the lower steering shaft does not fully secure the upper shaft. Mack identified the issue on trucks built with a 2-piece steering shaft, and the root cause was still under investigation in the recall filing. If the connection loosens enough, the steering shaft can separate and the driver's steering input no longer reaches the rest of the steering system.
There is no warning sign before failure. A truck can steer normally until the shaft connection separates, which is why the VIN check and dealer repair matter even if the steering feels normal today.

What should I do?
- Check your VIN to confirm your 2016-2017 Mack Titan (Td) is included in this recall.
- Do not drive the truck until a Mack dealer applies the steering-shaft remedy.
- Arrange a tow if the truck has to be moved to the dealer; do not drive it there yourself.
- Contact a franchised Mack dealer to schedule the free repair for the steering-shaft bolt that can separate and cause loss of steering.
- Bring the recall notice if Mack mailed one. If not, reference recall number 16V156 when you call.
What happens at the repair
Until Mack applies the interim repair, if your VIN is included, do not drive the truck. At the dealer, a Mack technician addresses the upper steering shaft connection to the lower steering shaft, then completes the final steering-shaft remedy once that repair is available under the recall. Both the interim and final recall work are free. Mack's reimbursement plan covers eligible steering-shaft repairs paid before the recall notice. Keep repair documentation and contact Mack customer service at 1-877-800-4945 opt #1 with prior repair questions.
