What's wrong?
The 2021-2023 Mack Lr Electric uses hydraulic power steering assist to help the driver turn a heavy truck with less steering effort. The assist system builds hydraulic pressure and applies it through the steering gear, so the wheel responds without requiring the driver to supply all of the force by hand. That support matters most at low speed and during quick steering inputs.
On affected trucks, engineering testing found that the hydraulic assist falls outside Mack's internal allowance during evasive maneuvering. During aggressive steering, the assist system loses pressure. When that pressure drops, the steering wheel takes more torque to turn and the driver loses power steering assist for that maneuver.
There is no warning sign before failure. The change is felt at the steering wheel when assist drops away, with steering effort rising during the driving maneuver instead of building gradually beforehand.

What's the safety risk?
If steering assist drops out, the truck becomes harder to steer, especially at low speeds, and the risk of a crash increases. Slow down, avoid tight maneuvers, and schedule service promptly if your VIN is included. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2021-2023 Mack Lr Electric is included in this recall.
- Contact a franchised Mack dealer to ask about the free steering-gear replacement and power-steering-pump software update that fixes the loss of power steering assist.
- Reference recall number 22V204 and Mack recall SC0434 when you call.
- Bring the owner letter if Mack mailed one to you.
- Drive with extra steering room until the repair is complete, since loss of power steering assist increases crash risk.
What happens at the repair
At the dealer, a Mack technician replaces the higher ratio steering gear and updates the power steering pump software so the steering pump uses higher RPM settings. The final dealer repair will be free once available; parts and labor are covered under the recall. Mack has a general reimbursement plan on file. If you already paid for a steering gear, power steering pump software, or related power steering repair before the notice, contact Mack customer service and keep repair documentation for the claim.
