Recall - Brake Vacuum Pump Replacement
No: SR-13-001REVIIDATE: March, 2013
MODEL: 2012 i-MiEV
SUBJECT:
2012 i-MiEV VACUUM PUMP - SAFETY RECALL CAMPAIGN
This bulletin supercedes SR-13-001REV, issued March, 2013 to clarify the replacement procedure. Changes are indicated by <.
PURPOSE
Certain brake vacuum pumps equipped on 2012 i-MiEV vehicles built between December 2, 2011 - September 7, 2012 may become inoperable due to failure of an internal component. If the vacuum pump becomes inoperable the brake warning light will illuminate and the brake warning buzzer will alert the vehicle operator. Vacuum pump inoperability will result in reduced brake power assist which may increase stopping distances and could lead to greater risk of crash.
Replacing the vacuum pump on affected vehicles will resolve this potential condition.
AFFECTED VEHICLES
Certain 2012 i-MiEV vehicles built between December 2, 2011 - September 7, 2012
IMPORTANT
Affected new or used inventory vehicles must be repaired before the vehicle is delivered. Dealers must check their inventory vehicles' VINs on the Warranty Super Screen to verily whether the vehicle is involved in this recall campaign. It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (Including a tire) covered by the notification under a sale or lease until the defect or non-compliance is remedied.
CUSTOMER NOTIFICATION
A letter will be sent to all owners of affected vehicles requesting them to schedule an appointment with their local certified Mitsubishi i-MiEV dealer to have their brake system vacuum pump replaced. A copy of the customer notification letter appears at the end of this bulletin.
