On 429 Mitsubishi i-MiEV electric cars from 2012-2013, vacuum pump operation could be affected by software defects and/or a blocked pump exhaust hole.
A non-operational vacuum pump would affect the power brake system, increasing brake pedal effort and potentially increasing stopping distances, which could increase the risk of a crash.
Mitsubishi dealers will therefore update vehicle software and replace the vacuum pump as necessary. Note: In the event that the vacuum pump fails, the brake warning lamp will illuminate and an audible warning will be heard.
