14,906 Toyota 86 vehicles recalled to fix power steering fault (Update: BRZ too)

Toyota Australia has announced a recall of 14,906 Toyota 86 vehicles to fix a potential issue with loss of power steering.

THE RECALL AFFECTS almost 15,000 Toyota 86 vehicles built between April 2012 and March 2015 which are right-hand-drive and equipped with driver’s knee airbags.

In a statement, Toyota said: “due to an improper wire harness layout, there is a possibility that the electric power steering harness may interfere with the instrumental panel lower cover which contains the driver’s knee airbag on Australian specification vehicles.”

“If this happens, there could be an electrical contact failure which may result in the loss of power steering assist. A warning light would then illuminate on the dashboard along with a short audible warning whilst manual steering would be maintained.”

The fix is to replace the power steering electronic control unit and related wiring harness. Toyota expects that the parts will arrive from late September, and affected owners will be contacted by registered mail to make an appointment at their dealer for the work to be done. The job takes a bit over an hour and is free of charge.

Toyota say there have been 62 reports in Australia of the condition occurring but no accidents or injuries reported as a result.

 

UPDATE: SUBARU BRZ AFFECTED TOO

Following Toyota Australia’s statement, Subaru Australia has also issued a recall of 3016 Model Year (MY) 2013-15 BRZ models.

Subaru said: “It is important to note that even if the power assistance for the steering is lost, the vehicle retains manual steering capability. Nevertheless, Subaru Australia has decided to carry out this recall out of an abundance of caution, following notification from the factory, Fuji Heavy Industries (FHI).

Like Toyota, Subaru said it would contact owners and advise them to make an appointment with their local Subaru dealer to have the recall work carried out free of charge.

The number of BRZs subjected to recall in each model year is:

Model Year (MY)        Number of vehicles

2013                            1194

2014                            929

2015                            893

 
Practical Motoring says: a power steering failure can feel strange, but the car has a mechanical steering system so it can still be steered and driven. You will suddenly find the steering much, much heavier and it will be particularly noticeable at slower speeds. This issue is not sufficiently critical that the cars needed to be taken off the road.
 
The 86 is also noted for having its power steering overheat under stress, noticeably slow-speed, tight motorkhanas where there is a lot of very quick steering work with no respite. The owner’s manual even make a note of this potential for overheating – the solution is simply to wait for the car to cool which doesn’t usually take very long. This recall is a separate issue to the overheating.

Toyota 86 Electric Power Steering (EPS) Assistance Q&A

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 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.

Q2: What is the function of the Electronic Power Steering?
A2: The electric power steering system generates torque to assist steering effort through operation of the motor and reduction gear installed on the steering column shaft.

The power steering electronic control unit (ECU) determines direction and the amount of assistance required in accordance with vehicle speed and signals from sensors built into the steering column assembly.

Q3: Which and how many vehicles are involved?
A3: There are 14,906 Toyota 86 vehicles involved in the Australian market.
