I left for work, acceleration at slow speed around 30 mph within 40 seconds, the car began to gain speed, I let off the gas pedal, still accelerated. I tried slowly using brakes to slow down - no response. At this point, I notice that cruise control light, was lit up, on the dashboard but not set. I'm now gaining speed of 72 MPH. Not even 1 mile, from turn off. I literally fish tailed three times, then the car slowed down and I ended up sideways, in a ditch. Chipped hubcap and some plastic piece hanging, from underneath the car. I had a bystander, whom was headed towards me - stop in fear of what happened. Got the car out of ditch. I parked, checked for leaks, nothing. Since this incident, I'm in fear of this happening again. I'm assumption was the accelerator stuck. No brakes is dangerous, let alone feeling like my life was gonna end. I cried. Thinking Jesus my children were home. I have noticed that both airbag "warning" signs have displayed and won't go off. I would hate to have or hear of a fatality, from this. Please look into other reports. I felt like I couldn't even explain this bizarre, unlikely/impossible event to happen but it did.
