| Description of the problem | On august 1st at approximately 10:11pm [144298 miles on the vehicle] at the i-10east to i-75south interchange after merging onto i-75 south. Traveling on i-10 east from tallahassee to orlando using the cruise control which was set at 75mph according to the speedometer - in order to take the i-75 southbound (tampa-orlando) exit i applied the brake to slow down and release the cruise control. Upon merging onto i-75 from the ramp i was traveling at about 55 to 60 mph and went to select resume on the cruise control. I removed my foot from the accelerator as i always do and let the cruise do the work. The vehicle accelerated as expected to 75 mph - the set point and stayed there for about 2 seconds (long enough for me to notice the speedometer pause at 75mph and then the vehicle accelerated fast and hard again (like full throttle) and kept going in about 2 seconds i was now at 85 and still accelerating; i applied my brakes to release the cruise control and slow the vehicle - it released the cruise and i was able to slow down - i did not use the cruise control after that. |
