Air bags

This is a follow-up and correction to a complaint previously submitted for VIN [redacted] regarding airbag non-deployment during a passenger-side T-bone collision on [redacted]. A [redacted] child was properly restrained in a rear-facing car seat in the rear passenger-side seat. The vehicle was struck directly on the passenger side at an estimated 30 mph. The front passenger door was deformed to the point it can no longer be opened. Despite this significant side impact and the presence of an occupied child seat in the rear, no side curtain airbags deployed-including those designed to protect rear outboard passengers. This vehicle is equipped with side curtain airbags as standard equipment. We believe this may constitute a failure of the Supplemental Restraint System (SRS) to perform as intended under FMVSS 214 and 226. …

On 05AUG25, my wife was involved in a frontal collision while driving our 2018 Mitsubishi Outlander Sport. The vehicle struck another vehicle at an estimated speed of over 30 mph, resulting in significant damage to the front passenger side, including deformation of the hood and front quarter panel. Despite the severity of the impact, no airbags deployed. My wife was properly restrained and sustained visible bruising across her torso. She is currently in her second trimester of pregnancy. The seatbelt force alone presented a serious safety risk to her and our unborn child. There were no airbag system warning lights prior to the collision, and the SRS appeared to be functioning normally. The failure of the airbags to deploy under these conditions indicates a potential defect in the supplemental restraint system. This appears to be a dangerous failure of the airbag system. …

I am filing this complaint regarding serious safety issues with my 2018 Mitsubishi Outlander Sport, VIN: [redacted] , purchased from Carvana in 2019. Recurring transmission problems have created a significant safety risk for me and others. About a year after purchase, the vehicle's transmission began failing, and I replaced it in 2021. Despite this, the transmission warning light activates intermittently in stop-and-go traffic, and now the vehicle has started stalling on highways, creating a critical hazard by suddenly losing power. In 2021, I took the vehicle to a now-closed Mitsubishi dealership in Brooklyn, where I was informed that this transmission issue was not covered, despite it being a drivetrain problem that should have been under the 100,000-mile powertrain warranty. …
