What's wrong?
The 2024 E-One Cyclone N and Typhoon N use an independent front suspension assembly at the front axle. In that system, the lower control arm helps hold the wheel and suspension in position as the truck steers, brakes, and carries weight. Retention bolts clamp that lower arm into place, so the joint depends on the bolts staying strong after installation.
On affected trucks, the bolts used in the independent front suspension were stripped of their original coating and re-plated with zinc. That process caused hydrogen embrittlement, which means hydrogen made the metal brittle. After the bolts were tightened, a brittle bolt can break instead of holding clamp force on the lower control arm.
There is no warning sign before failure. An owner or fleet should not expect looseness, noise, or a dashboard warning before a bolt breaks, so the vehicle needs recall handling even without symptoms.
