Vehicles affected by service bulletin:
2014 Mitsubishi Mirage
2015 Mitsubishi Mirage
Equipped with continuously variable automatic transmission and built before Jan. 19, 2015.
The problem: Due to a rich air-fuel ratio, the vehicle may stall at low engine speeds just prior to stopping or during idling when operating in high ambient temperatures. This could lead to positive crankcase ventilation hose disconnection.
Corrective action: Dealers will reprogram the engine control module software to optimize the air-fuel ratio and eliminate the problem.
Warranty info: This repair is being done free of charge under the new-vehicle limited warranty.
What owners should do: Call your local dealer with your vehicle's identification number to determine if it's involved in this service bulletin. You can also call Mitsubishi at 888-648-7820 or NHTSA at 888-327-4236. Reference TSB No. 15-13-001R2.
