Reported at 44,000 miles, February 2010 CrashInjury

I was involved in an auto rollover accident on January2, 2023 when a driver "t-boned" me in my 2008 Infiniti Qx56 striking the middle of the passenger side of my Qx56 after running a stop sign and failing to yield to my right of way causing my Qx56 to roll over 3 times. My driver's steering wheel airbag did NOT deploy. To my knowledge all the other airbags did deploy. I suffered neck, right shoulder, and lower back injuries from the rollover but remained in the driver's seat as the seatbelt system worked well.

The contact stated that while driving approximately 10 MPH and depressing the brake pedal, she noticed a vibration in the pedal and the vehicle would not stop. The brake light, vdc and the ABS warning lights illuminated on the instrument panel. The failure recurred six times while the contact was traveling at different speeds. The vehicle was taken to the dealer six different times.

Reported at 48,670 miles, September 2011 Crash

On 9-4-2011 I left tallahassee, florida. As I got to the edge of town I noticed it started to idle slightly high. By the time I got to thomasville, georgia, it would accelerate to about 45 MPH without any acceleration pressure and the brakes were required frequently. Between thomasville and moultrie, georgia, it would accelerate independently but it would drop down if I pressed and released the accelerator. It also seemed to maintain speed a bit better if I used the cruise control.
