1,810 i-MiEV (including some demos build in 2009) Were Recalled In The US
The Recall Does Not Affect Newer/Recently Built (post March 25th) i-MiEVs
All Mitsubishi model year cars between 2010 and 2014 have been recalled in the United States as a failure can occur in the brake vacuum pump.
And has most people enjoy stopping in a reasonable amount of distance, Mitsu is bring all the cars - some 1,810 worth, back to the shop for repairs. The cars in the recall were build from September 15, 2009 to March 25, 2014.
Sidenote: if you are thinking what model year 2010 i-MiEVs build in 2009 ever made it to the US, well there was 4 demo cars sent over the pond...apparently they are still out there somewhere.
Per the NHSTA on the problem:
Description of the Defect: The brake vacuum pump may become inoperable. Description of the Safety Risk : Brake vacuum pump inoperability may result in increased stopping distances, which can increase the risk of crash. Description of the Cause : Due to either of the following two reasons, the brake vacuum pump may become inoperable:
- 1) Improper programming of the EV-ECU, which controls the brake vacuum pump, may cause the ECU to falsely judge that the relay contact point is stuck.
- 2) Due to the location of the brake vacuum pump exhaust hole, mud containing road salt could enter and adhere to it, causing the exhaust hole to be blocked from corrosion of the aluminum portion.
As a solution, Mitsubishi will reprogram the software and/or replace the pump itself.
