Toyota Motor Corporation is preparing a recall of Lexus LS models equipped with Variable Gear Ratio Steering (VGRS). The number of cars involved is still being finalised but initial figures show approximately 11,500 affected vehicles globally.
VGRS is a feature that enables easier handling during low speed driving and better stability at high speeds by changing the gear ratio. The LS’ problem occurs at low speed when manoeuvring the steering wheel to full lock position. If the driver then returns the steering wheel very fast, this could lead to a steering wheel off-centre condition even though the driving wheels would be straight.
This phenomenon will be resolved automatically in a few seconds and the driver may notice this correction as the steering wheel moves slowly by itself to the centre position when driving straight during the correction operation. The driver remains in control of the vehicle as the steering wheel self corrects itself.
This matter has been under investigation by TMC since March this year after have received approximately 10 complaints in Japan. No accidents have been reported relating to this issue and no other Lexus vehicles are affected.
A quick check at Lexus Malaysia’s website show that both LS models sold here – the LS 460L and LS 460 Sport – come with VGRS. The company should be already in touch with customers of the big limo. We’ll post updates, if any.
