Driving on the NYS Thruway with Cruise Control on and it dropped out. I tried to reengage several times and it would not engage. On the way home I tried it again it kicked on and kicked off right away and since this incident I've had no cruise control. I researched recalls and see there are 3 1999 Recall 99V124000, Electrical System. 2007 Recall07V336000 Vehicle Speed Control. 2008 Recall 08V051000 Speed Control Recall. I spoke with Ford and they suggested I spoke with the Ford they said to contact the federal safety agency. My car has less than 60,000 miles and has been well maintained so this is concerning me. The car is from Florida. Checked the fuse they are fine.

While entering onto the woodrow wilson bridge from I-295s on 2/1/2018, I pulled into the center lane and backed off the gas pedal, but the car continued to accelerate on its own. Luckily the traffic was light, after hitting the brake and the off button for the cruise control, to no effect, I was able to pull into the right lane and turn the car off. While still in motion, I turned the key back on and everything was normal again. Since it wasn't a cruise control issue, it would appear it is similar to the toyota problem with the drive by wire issue.
