UMW Toyota Motor (UMWT) has announced a recall to replace potentially faulty airbag sensors on selected units of the Toyota Corolla Altis as well as the Lexus NX and RX. The recall is part of the same exercise by Toyota Motor Corporation (TMC), which was revealed on January 31.

Based on information from TMC, 2,800 units of the Corolla Altis are affected, and around 500 units of the NX and RX. The affected cars were were manufactured from June 2015 to January 2016, and distributed by UMWT and Lexus Malaysia.

In detail, the defect relates to manufacturing issues where there is a possibility the insulation used for integrated circuit (IC) chips in affected pressure sensors and G sensors could peel off over time, creating an open circuit in the IC chip.

This could cause the airbag warning light to illuminate, and the side/curtain airbags and/or front airbags could also be deactivated and will not deploy when required to. This increases the risk of injury to occupants in the event of a crash.

Affected vehicle owners will be notified by UMWT, when parts are available, to bring their cars to an authorised Toyota or Lexus service centre for necessary replacements. The process should take about 30 minutes to four hours (depending on the model), with all costs involved for the replacement being borne by UMWT.

The company says Toyota customers can contact Toyota service centres or get in touch by Toyota Freephone at 1800-8-TOYOTA (869682). There’s also a dedicated webpage for customers to check if their vehicle is involved using a VIN checker, which you can find here. For Lexus owners, customers can contact Lexus authorised dealers nationwide or contact its Freephone at 1800-88-LEXUS (53987) or visit
