UMW Toyota Motor (UMWT) has announced a special service campaign (a.k.a. recall) to update the hybrid software of the third-generation Toyota Prius.

A total of 6,160 units of the Prius sold by UMWT and manufactured from 2009 to 2013 are involved in this recall, which “serves to provide an additional remedy to the vehicles involved in the previous recall announced in 2014.”

UMWT does not elaborate, but a quick search reveals that Toyota has just announced a recall of more than 2.4 million hybrid vehicles worldwide produced between October 2008 and November 2014. A fault in the system can cause the cars to lose power.

“While power steering and braking would remain operational, a vehicle stall while driving at higher speeds could increase the risk of a crash,” the company said, adding that “the remedy conducted then (previous recalls in 2014 and 2015) did not anticipate the new condition identified in this recall.” There have not been any reported cases in Malaysia.

UMWT will notify all affected vehicle owners to update the ECU programming at no charge. The process should take around an hour. Know someone who drives a third-gen Prius? Do help to notify them.
