Mitsubishi Recalls i-MiEV: Third Time’s The Charm?

For the third time, Mitsubishi has recalled the 2012-2017 i-MiEV for potential vacuum pump failure. The vehicles are battery-electric and therefore have no way to produce vacuum for brake boosting other than with an electric pump.

While the -MiEV was discontinued by the company, the car has been plagued with braking trouble related to the booster.

According to Mitsubishi, water may get into the brake assist vacuum pump, causing corrosion and eventual failure of the pump.

If the brake vacuum pump fails, it causes a loss of braking assist, increasing the distance required to stop.

It’s a problem Mitsubishi knows all too well, according to, as the automaker recalled the cars for vacuum pump problems in 2013 and in 2014. Then in May 2019, the National Highway Traffic Safety Administration (NHTSA) opened a formal investigation into Mitsubishi’s recalls of the i-MiEVs.
