NHTSA Complaint #11686056 — 2007 FORD CROWN VICTORIA

My 2007 Crown Victoria has had a worsening unintended acceleration issue over the past year. When hitting hard bumps the car will suddenly begin revving my itself (normal RPM is 600 idling in drive and 800 idling in neutral) when this issue occurs it will sit around 1k rpm in drive (pushing against the brakes so I must hold them down very hard) and will shoot up to 2k rpm in neutral. when the issue is occurring it drives the car forward with no user input. this issue has been becoming more and more frequent with it happening up to 5 times in a 15 minute drive. It is very unsafe and has caused me to hit a parking pole before as I could not slow the car down fully.
