Cruise Control problems of the 2008 Hyundai Santa Fe

The contact owns a 2008 Hyundai Santa Fe. The contact stated while driving at an undisclosed speed with the cruise control activated, the contact stated that after depressing the brake pedal the cruise control briefly failed to disengage. The vehicle returned to normal functionality, but the failure became a regular occurrence. The electronic power control (epc) and power train warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the stop lamp switch. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA campaign number: 13v113000 (exterior lighting); the VIN was included, but the vehicle had already been repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 195,000.

6/25/14, on interstate with cruise control at 65mph. Depressed the throttle pedal to pass a vehicle. Throttle stuck wide open. Applied brakes but kept on increasing speed. Depressed throttle pedal several times but no change. Turned cruise control off, no change. Turned key to acc and then back to on but no change. Turned key to acc and waited several seconds then back on. Throttle pedal started to respond. Pulled over and checked if floor mat was jamming throttle pedal. No problem, no jamming. Problem repeated again. Continued to destination and tried cruise control but it would not set. Turned cruise conrol off. SUV was parked overnight at destination. On return trip throttle and cruise control worked fine. 6/30/14, took SUV to ray brandt Hyundai, they found no codes set and could not dupilicate the problem. It seems if both the throttle is wide open and the brakes are being applied then a code should be set. . Read more...

Was on an interstate with cruise control set to 65 mph. Was attempting to pass another vehicle, thus depressed the throttle pedal. The throttle stuck wide open. Applied brakes but kept on increasing speed. Depressed throttle pedal several times but no change. Turned cruise control off, no change. Had to pull over, put vehicle in park with brake pressed and turned key off. Waited several minutes then back on, throttle pedal started to respond. Second instance, was accelerating to merge onto interstate from a ramp, had previously had cruise control set to 65 mph, throttle stuck wide open, again had to pulled over, put the vehicle into park, and turn off ignition . I checked to ensure floor mat was not interferring throttle pedal, it was not. Problem has recurred 4 times now on this vehicle all while trying to accelerate to either pass a vehicle or merge onto an interstate. All times the cruise control had been engaged.

While driving my 2008 Hyundai santa on the highway on two separate occasions last week my Santa Fe decelerated unexpected to ~ 20 mph. The first time the car was on cruise control and started to lose power, the second time I was also using the cruise control and the same problem occurred. At the same time the esc warning light came on followed by the check engine light. The temperature was cold but the road conditions were dry the vehicle failed to accelerate. I took the car to the dealer and the they were able to fix it by replacing a sensor. This could have resulted in a very dangerous situation on the highway. The SUV failure and current mileage is ~ 25,400 miles.
