|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | November 4, 2010 |

Defect
The control software for the electric power steering (EPS) control computer is incorrect. When the vehicle is driven at high speed over rumble strips installed for lane departure warning, the computer may misinterpret the resulting vibration and shut down EPS assist. This causes the steering to become heavy.
Corrective action
On vehicles where the control computer software can be updated, reprogram the software. On all other vehicles, replace the entire steering column assembly with one incorporating a corrected/revised part control computer.
