# Service bulletin 18245

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- [18296](/bulletins/10147333.md), 2018-11-13, Service bulletin: STEERING: STEERING WHEEL/HANDLE BAR; STEERING:LINKAGES:TIE ROD ASSEMBLY. 18296 \- Service Update \- Left front tie rod jam nut may be below torque specification, \(75 \+/\- 15 Nm\). Because the jam nut may be below torque spec, it could loosen and result in wheel alignment \(toe\) changing while driving. Drivers may notice a squeak noise when turning or hitting bumps, a loose feeling in the steering, or shaking in the steering wheel on bumps. In extreme cases the tie rod end could become disconnected, resulting in a loss of steering control. Perform toe adjustment and secure all fasteners to correct torque.
