Filing in context
The Computer (steering) is the most frequently cited component category in this archive, appearing in 7 of its 4,890 filings. This filing is one of 21 Toyota notifications from 2010 in this archive. For scale, 657 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 1 year and 11 months.
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.
