The contact owned a 2020 Mazda CX-9. The contact stated that while driving approximately 60 MPH, a second vehicle crashed head-on into the front of the vehicle. During the head-on crash, no air bags inside the vehicle deployed. The contact sustained a concussion and right eye injury and later received medical attention. A Police report was filed at the scene. The vehicle was destroyed and towed to a local storage facility. No information was available concerning the second vehicle's occupants.
The mazda cx-9 uncommanded engine acceleration reported herein did not result in any damage primarily because it commenced several seconds after I began light braking while approaching a red traffic light. My immediate response was to increase brake pressure; there was no need for me to move my leg other than pressing harder with my foot. My foot had been off the accelerator for many seconds while allowing the car to slowly decelerate while coasting toward traffic stopped at a red light.
Fuel cap light on in dec 2020. Our car mileage ~14,000 miles . We bought brand new cx9 2020 in august. Dealer inspected it and found nothing wrong. Dealer reprogrammed it. A month later jan 1,2021, fuel cap light is on on again. We ignored it thinking it is another program issue. Car started to jerk and vibrate at stop sign. We brought to dealer the next day. Dealer said charcoal box is leaking. I thought charcoal box should last a life time.
