Here's the key finding:
"While a final report is not yet complete, there are strong indications that the driver's account of the event is inconsistent with the findings of the preliminary analysis.
The investigation revealed the following initial findings:
• The accelerator pedal was tested and found to be working normally with no
mechanical binding or friction. It should be noted that the Prius is not subject to a recall for sticking accelerator pedals and the Prius component is made by a different supplier than the one recalled.
• The front brakes showed severe wear and damage from overheating. The rear brakes and parking brake were in good condition and functional.
• A Toyota carpeted floor mat of the correct type for the vehicle was installed but not secured to the retention hooks. It was not found to be interfering or even touching the accelerator pedal.
• The pushbutton power switch worked normally and shut the vehicle off when depressed for 3 seconds as the 911 operator advised Mr. Sikes to do.
• The shift lever also worked normally and neutral could be selected. The neutral position is clearly marked and can be easily engaged by moving the lever left to the "N" marking.
• There were no diagnostic trouble codes found in the power management computer, nor was the dashboard malfunction indicator light activated. The hybrid self- diagnostic system did show evidence of numerous, rapidly repeated on-and- off applications of both the accelerator and the brake pedals.
• After examination of individual components, the front brakes were replaced and the vehicle was test driven, during which the vehicle was observed to be functioning normally.
• During testing, the brakes were purposely abused by continuous light application in order to overheat them. The vehicle could be safely stopped by means of the brake pedal, even when overheated.
