Prius computer fault prompts recall

Prius computer fault prompts recall

Toyota has launched a recall of almost 31,000 UK-registered Prius cars due to a computer fault that could cause the vehicle to stop.

The recall - which applies to 30,970 cars manufactured between March 2009 and February 2014 - is the latest in a series of recalls in recent years affecting the Prius and other Toyota cars.

Toyota confirmed there have been 11 incidents in Europe involving the computer problem, but it has not led to any accidents or injuries.

Drivers of other Toyota models may be reassured, however, by the carmaker's announcement that the problem will not occur in its other hybrid vehicles as they run on different systems.

The possible glitch relates to the software "used to control the boost converter in the intelligent power module" of the Prius.

It "could lead to higher thermal stress" which in turn could result in certain insulated-gate bipolar transistors in the boost converter becoming damaged, causing the car to switch to "failsafe" mode resulting in a drop in power.

"In limited cases the hybrid system may shut down, causing the vehicle to stop. The driver will not experience any change in the vehicle's behaviour or performance prior to the problem occurring," Toyota added.

UK Prius owners affected by the move - part of a wider recall of 1.9 million Prius models worldwide - will have their control software updated to address the problem.
