The 2009 Infiniti M35 has 4 recalls, the most serious being a passenger-side airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death.
Prior repair attempts did not fully resolve this issue, and multiple campaigns have addressed the same defect across different affected populations. The airbag inflator concern should be treated as the primary priority for this vehicle. On the mechanical side, the accelerator pedal sensor can degrade over time and send an incorrect signal to the engine, causing it to drop into a reduced-power mode. In that state, throttle deposits can cause the engine to stall when slowing to a stop or sitting at idle, which raises the risk of a crash.
