Q1: What is the condition?
A1: The subject vehicles are equipped with electric power steering (EPS).
During normal driving operation, the EPS rotation angle sensor terminals may wear over time. This wear of the connector terminal plating accumulates in debris which may oxidise and become non-conductive.
Under this condition if the driver’s knee contacts the knee airbag lower cover, the EPS wire harness routed behind the cover also moves significantly which allows the terminal to contact the debris resulting in electrical contact failure.
In this condition, the EPS ECU turns on the warning light and the steering assist is interrupted whilst manual steering is maintained.
The loss of power steering assist will increase the steering effort at low speeds which may increase the risk of an accident.



You guys might not get the recall, but it may be possible for the same fault to develop, given a different set of circumstances ?

Possible maybe but so unlikely that it is immeasurable. The situation you had took a perfect storm of circumstances for it to occur. Remove any of those conditions and the probability drops huge. We have no airbag nor cover and the wiring is routed completely different. No doubt they checked to make sure that this was the only model that it was probable on. Toyota Australia seems to be pretty tight with the TSB info so it would be interesting to see what their fix was.
