2011 Jeep Grand Cherokee vehicle speed control problems

“Malfunction of the engine RPM governor, adaptive cruise control, or Electronic Throttle Control (ETC), or some combination of all of the above. On June 7-9, 2022, spontaneous high engine RPM occurred, which resulted in vehicle speeds that were above urban speed limits unless heavy braking pressure was applied. Additionally, on rural highways, the speed setting for the adaptive cruise control was exceeded without driver input. This also required manual breaking in order to control speed. During this situation, the “driver override “ message would appear although no accelerator pedal pressure was being applied. Additionally, the ETC warning light would randomly light up and then clear. When the vehicle was stopped and placed in park, the engine would rev to approximately 4000-5000 RPM. Especially in congested traffic conditions, this runaway engine RPM condition is a terrifying situation. This malfunction has occurred on this vehicle before, and to a similar extent. However, the Jeep dealer could find no underlying cause. The vehicle will also occasionally operate at a higher than normal RPM, but not to the extent described here. I do have an appointment with my…”

“The contact owns a 2011 Jeep Grand Cherokee. The contact stated that while pulling into a parking space with the foot on the brake pedal, the vehicle suddenly experienced unintended acceleration causing the driver to lose control of the steering wheel and crashed into a building.

A police report was taken at the scene and the vehicle was towed away. The cause of the failure was not determined. The local dealer and manufacturer were not contacted. The VIN was not available. The failure mileage was 66,000.”

“FOR THE PAST FEW WEEKS, MY 2011 JEEP GRAND CHEROKEE HAS BEEN STALLING WHILE DRIVING. THE FIRST TIME IT HAPPENED, I WAS IN A LINE OF TRAFFIC, HAD JUST COME A UP A HILL, I PRESSED THE GAS PEDAL, MY CAR BUCKED, AND THEN MY CAR "STALLED". THANKFULLY, WE KEPT COASTING, BECAUSE, LIKE I SAID, WE WERE IN A LONG LINE OF TRAFFIC GOING 50 MPH ON A MAJOR ROAD. I PULLED OVER, SHUT MY CAR OFF, TURNED IT BACK ON, AND WAS ABLE TO DRIVE US THE TWO MILES TO GET BACK HOME. I NO LONGER FEEL SAFE DRIVING MY TWO CHILDREN IN MY GRAND CHEROKEE, THEREFORE MY HUSBAND HAS BEEN DRIVING MY CAR AND I'VE BEEN DRIVING HIS. SO FAR THIS WEEK, THE GRAND CHEROKEE HAS STALLED SIX TIMES WHILE MY HUSBAND IS DRIVING, USUALLY WHILE HE IS ACCELERATING TO GET ONTO THE HIGHWAY. THERE IS A RECALL ON THE GRAND CHEROKEE; 19V-813, WHICH DESCRIBES A FAULTY FUEL PUMP RELAY. HOWEVER, THERE IS NO FIX AVAILABLE THROUGH JEEP. WE HAVE CONTACTED SEVERAL AUTHORIZED JEEP DEALERS IN THE OUR AREA AND NO ONE WILL OFFER ANY ASSISTANCE THAT RELATES TO THE RECALL. I BELIEVE THAT THE PROBLEM IS NOT JUST THE FUEL PUMP RELAY, BUT THE TOTALLY INTEGRATED POWER MODULE OR TIPM. I'M HAVING NUMEROUS OTHER ELECTRICAL PROBLEMS WITH MY…”

“TWO RECENT EVENTS, WHEN BRAKING IN SLOW TRAFFIC THERE WAS SUDDEN ACCELERATION WITH FOOT ON BRAKE. EVEN WITH STRONGER AND FORCEFUL BRAKE PRESSURE THE JEEP WAS STILL MOVING AND WANTING TO KEEP GOING WITH ENGINE REVVING. HAD TO SHIFT INTO NEUTRAL AND THEN ENGINE QUIT REVVING AND THINGS RETURNED TO NORMAL. I HAVE THIS JEEP 10 YEARS AND AM VERY FAMILIAR WITH IT. NEVER ANY WRECKS. NO MEDICAL PROBLEMS. THE FLOOR MAT WAS NOT INTERFERING WITH ANY PEDALS. THE DEALERSHIP WAS NOT AWARE OF ANY RECALLS ABOUT THIS PROBLEM BUT THEY SERVICED THE THROTTLE-BODY AFTER THE FIRST INCIDENT. THIS APPARENTLY WAS NOT THE PROBLEM AS THE UNINTENDED ACCELERATION WHEN BRAKING OCCURRED A SECOND TIME. IN GOOGLING THIS PROBLEM A BLOG MENTIONED THIS COULD BE THE JEEP BRAKE-BOOSTER WHICH HAS BEEN RECALLED AND WAS REPLACED ON MY JEEP 2 YEARS AGO. GOOGLE BRINGS UP THIS SUDDEN ACCELERATION AS A COMMON SEARCH BUT NO CLEAR ANSWERS. I KNOW ABOUT THE TOYOTA ACCELERATION PROBLEM IN THE 1990'S, THAT THEY NEVER FOUND OR ADMITTED ANYTHING MECHANICAL AND ASSUMED IT WAS GRANNY USING TWO FEET. THIS IS ABSOLUTELY A MECHANICAL PROBLEM WITH MY 2011 JEEP. WILL TAKE TO DEALERSHIP BUT THEY ALREADY SAID THEY AREN'T…”
