Front Collision Mitigation System, FCM, failed on frontal impact and airbags did not deploy. Vehicle did not activate audible or display emergency warning signals prior to frontal impact. We filed a complaint with Mitsubishi Motors national CR, and Director of Service with many calls, voicemails and emails just fell on deaf ears. Their response documented in the case report on the last call we made to Mitsubishi Motors on 6/17/22 the CR rep said the decision is final and that they would not do anything, and we should contact our insurance. Mitsubishi's not only "Did not inspect the vehicle" but also never inquired with any intelligent questions as to why the airbags and FCM system failed to operate. Vehicle has not been inspected by anyone and is currently in my garage with less then 400 miles on it and is available for inspection. No prior warning lights were displayed. The dashboard currently displays crash signal and forward warning lights.
