AIR BAGS26/04/2019

Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2017-2018 Mirage G4 vehicles. The internal acceleration sensor in the Supplemental Restraint System (SRS) Electronic Control Unit (ECU) can misinterpret vibrations, such as from poor road conditions or a flat tire, as a malfunction and disable all the vehicle's air bags.

Risk: Air bags that do not deploy increase the risk of injury in a crash.

Fix: MMNA notified owners, and dealers will reprogram the SRS-ECU software, free of charge. The recall began May 24, 2019. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-19-001.
