2007 GMC Yukon Fuel system Problems

Travelling on an FM road, going 55 when Yukon began accelerating on its own, even when I took foot off the accelerator. tapped brakes, thinking cruise control had engaged. Vehicle swerved violently. Speed kept increasing. Saw I was traveling 75mph! Braked hard! Felt as if acceleration was fighting against the brakes. Then spun out in the middle of the highway, spinning around 1 1/2 times while fully braking. Finally I slowed enough to throw it into park, regardless of what it might do to my transmission, I had to stop the vehicle. I came to rest straddling the lane I had been in and the oncoming lane, facing the direction from which I came. Traffic behind me had seen my struggles in time to stop back far enough that they weren’t endangered and there was no oncoming traffic at that moment. The fuel propulsion system (throttle?) seems to be at fault. There was no warning on the dash about any issue prior to this. The issue was real, a danger to myself and others. A mechanic examined the vehicle and discovered accumulation of debris on top of connector under the hood. He believed just enough water caused the conductivity needed to trigger the acceleration. State that these vehicles allow more intrusion from wheel well area than most. He thoroughly cleaned all connectors and no further issues have happened (yet!) Further research uncovered a report on ‘Sudden Unintended Acceleration’. The link follows: https://www.gmfullsize.com/threads/sudden-unintended-acceleration-gm-full-size-trucks.327479/ I also have a report quoting all the GM document #'s if need be.

ON 10/08/2020 I WAS DRIVING IN HEAVY TRAFFIC AT 5 PM WHEN THE ENGINE LOST POWER AND THE DASH STARTED FLASHING FIRST IT WAS TURNING OFF THE STABILITY CONTROL SYSTEM AND THE NEXT MESSAGE WAS GOING INTO REDUCED ENGINE POWER MODE. AT THAT POINT, THE VEHICLE DROPPED TO ABOUT 30 MPH WITH FULL THROTTLE AND I HAD TO MANEUVER THRU TRAFFIC TO GET OFF THE FREEWAY. NOT EASY TO DO WITH A CAR THAT WILL ONLY DO 30 MPH OR SO. WITH CAUTION LIGHTS BLINKING AND WAVING AT CARS I NEARLY GOT REAR-ENDED TWICE BEFORE I COULD GET OFF THE FREEWAY.

THIS IS ANOTHER INCIDENT THAT OCCURRED THE SAME WEEK AS MY LAST COMPLAINT. WHILE DRIVING HOME FROM LUNCH I SLOWED THE VEHICLE AS I WAS GOING DOWN A HILL, THIS DID NOT REQUIRE ANY USE OF THE ACCELERATOR PEDAL. UPON SLOWING DOWN MY VEHICLE DISPLAYED THE FOLLOWING MESSAGES: "SERVICE TRACTION CONTROL", "SERVICE STABILITRACK", "REDUCED ENGINE POWER". THE SUV WOULD NOT ACCELERATE OVER 15MPH REQUIRING MY TO PULL TO THE SIDE OF THE ROAD. THE VEHICLE SHOOK VIOLENTLY UNTIL I WAS ABLE TO PUT IT IN PARK AND TURN OFF THE ENGINE. AFTER 10 MINUTES OF SITTING ON THE SIDE OF THE ROAD I STARED THE ENGINE AGAIN. THE SUV STARTED RIGHT UP BUT THE "CHECK ENGINE" LIGHT REMAINED ON UNTIL THE FOLLOWING DAY. ENGINE CODES LEAD TO A FAULTY THROTTLE BODY POSITION SENSOR WHICH WAS REPLACED AFTER THE INCIDENT ON 7/13. I TOOK MY VEHICLE TO THE GMC DEALER TODAY WHO INFORMED ME OF THE SAME PROBLEM YET AGAIN. THESE ARE EITHER BAD PARTS OR A SOME BIGGER GM ISSUE.

AFTER 10 MINUTES OF SITTING ON THE SIDE OF THE ROAD I STARED THE ENGINE AGAIN. THE SUV STARTED RIGHT UP BUT THE "CHECK ENGINE" LIGHT REMAINED ON. THIS WAS A TERRIFYING EXPERIENCE ON A BUSY STRETCH OF HWY 88 OUTSIDE OF CHICAGO. I HOPE OTHERS DO NOT HAVE TO GO THROUGH THIS EXPERIENCE.

VEHICLE GETS EXTREMELY LOW GAS, 13 MPG ON AVERAGE. BURNS OIL . NEED TO ADD 2-3 QUARTS OF OIL BETWEEN OIL CHANGES. ENGINE COOLING FAN STAYS ON FOR EXTENDED PERIODS WHILE DRIVING. ALL OF WHICH THE DEALERSHIP SAYS IS NORMAL FOR THE TRUCK. THEY REMOVED THE DRIVESHAFT BECAUSE OF CLUNKING AT 25K MI. REACTION CARRIER REPLACED AND TRANSMISSION RECONDITIONED AT 36,663 MI AFTER CAR STOPPED IN THE MIDDLE OF THE STREET. CAR HAD TO BE TOWED IN. AT 62K MILES ENGINE LIGHT ON AND IDLES ROUGH. REPLACED THROTTLE BODY. AT 67K WON'T ENGAGE IN REVERSE AND MAKES CLUNKING SOUND FROM REVERSE TO DRIVE. REPLACED REVERSE HOUSING, REACTION SHELL, ETC. AT 75K HAD A REACTION CARRIER FAILURE, LOST POWER BRAKES AND LOST POWER TO THE CAR. ALMOST WAS REAR ENDED. HAD TO STOP IN MIDDLE OF PARKING LOT DURING CHRISTMAS RUSH. WAITED 5 MIN AND RESTARTED. ENGINE LIGHT STAYED ON, BUT WAS ABLE TO GET TO DEALERSHIP. WAS TOLD THAT THROTTLE BODY NEEDS TO BE CLEANED EVERY 15K MILES UNDER SERVICE MAINTENANCE. THIS WAS THE FIRST TIME I HEARD THIS! NOT REALLY SURE WHY IT HAD TO BE CLEANED, THOUGH, JUST HAD THE THROTTLE BODY REPLACED 13K MILES AGO. IT SEEMS THAT THERE ARE MAJOR FLAWS IN THE DESIGN OF THE ENGINE. OBVIOUSLY, THE DEALERSHIP HAS BEEN PUTTING BAND AIDS ON MY PROBLEM BECAUSE THEY DON'T KNOW HOW TO FIX. I HAVE BEEN VERY LUCKY THAT MY FAMILY AND CHILDREN HAVE NOT BEEN IN A MAJOR ACCIDENT DUE TO THE MAJOR FLAWS IN THE ENGINE DESIGNS. EVERY TIME I GET MY CAR FIXED, THE TECH ASSURES ME THAT THEY HAVE FIXED THE PROBLEM. I AM REALLY AFRAID TO DRIVE THIS CAR WITH SO MANY CLOSE CALLS. THE CAR IS A HAZARD TO DRIVE! *TR
