What's wrong?
The brake vacuum pump is part of the power brake assist system on the 2010-2014 Mitsubishi I-Miev. This pump supplies vacuum assist so the brake pedal does not need heavy leg pressure during normal stops. The brake system still uses hydraulic pressure, but the pump helps the driver apply that pressure with less effort.
On affected vehicles, the pump can stop working for two different reasons. Improper programming in the EV-ECU, the electronic control unit that manages the electric vehicle system, can falsely read a stuck relay contact and shut the pump down. Road salt can also enter through the pump exhaust hole, mix with mud, and corrode the aluminum area until the exhaust hole becomes blocked.
When the pump becomes inoperable, the brake warning lamp illuminates and an audible warning alerts the driver. If that warning appears, the power assist is not working as designed, so the brake pedal requires more force than normal.
Who's affected?
Covers five model years of the I-Miev, all tied to the same hydraulic brake system.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific hatchback is included.
What's the safety risk?
If the brake vacuum pump stops working, the vehicle needs more distance to stop, which increases crash risk. A brake warning lamp and audible alert signal that the pump has become inoperable. If either warning appears, pull over safely and contact a Mitsubishi dealer before continuing. Repair is free at any franchised Mitsubishi dealer.
What should I do?
- Check your VIN to confirm your 2010-2014 Mitsubishi I-Miev is included in this recall.
- Contact a franchised Mitsubishi dealer to schedule the free brake vacuum pump repair, which is a controller reprogramming, pump replacement, or both.
- Bring the recall notice if Mitsubishi mailed one. If not, reference recall number 14V522 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance because brake assist can be reduced.
- Call Mitsubishi customer service at 1-888-648-7820 with questions, and reference Mitsubishi recall SR-14-007.
What happens at the repair
At the dealer, a Mitsubishi technician checks which repair applies to the affected vehicle. The dealer reprograms the brake vacuum pump controller, replaces the brake vacuum pump, or does both. The recall repair is available now, and parts and labor are free. If you already paid out of pocket for a repair tied to this recall, contact the Mitsubishi Customer Relations Department for refund instructions from the owner letter. Ask what documentation to submit with the reimbursement claim.

Frequently asked questions
What is recall 14V522?
Recall 14V522 covers 1,810 2010-2014 Mitsubishi I-Miev electric vehicles with a brake vacuum pump problem tied to software programming or road-salt corrosion. If the pump stops working, stopping distance can increase. Mitsubishi dealers will reprogram the controller, replace the pump, or do both for free.
What should I do if my 2010-2014 Mitsubishi I-Miev is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 14V522. If it is, contact a franchised Mitsubishi dealer to schedule the brake vacuum pump controller reprogramming, pump replacement, or both. Reference recall number 14V522 and Mitsubishi recall SR-14-007 when you call.
Is the recall repair free?
Yes. Mitsubishi's recall remedy says dealers will reprogram the brake vacuum pump controller, replace the brake vacuum pump, or do both free of charge. Federal recall law also requires the manufacturer to provide the recall repair at no cost at a franchised Mitsubishi dealer.
What is the safety risk?
The safety risk is longer stopping distance if the brake vacuum pump stops functioning. That loss of brake assist can increase crash risk, especially when quick braking is needed. Confirm your VIN, then have a Mitsubishi dealer complete the free recall repair.
What if I bought my Mitsubishi I-Miev used?
The free recall repair still applies. Recalls follow the vehicle, not the first owner. If you did not receive the 2014 owner notice, check your VIN to confirm whether your I-Miev is included, then call a franchised Mitsubishi dealer or Mitsubishi customer service at 1-888-648-7820.
