2007 GMC YUKON XL Engine Problems

Thr lifters shut down the engine and caused it to completely turn off the vehicle while in motion. It is available for inspection. Has not been confirmed by dealer. The code read cylinder 1 misfire but the lifters were not functional. The seizure of the engine and full stop of the vehicle while in motion nearly caused a 3 car pile up and a close collision into a fire hydrant as the steering locked and emergency brakes were not functional. There was no other warning lamps or messages offered prior to the shut down.

WHILE I WAS DRIVING THE STABILITRAK OFF LIGHT FLASHED ON THE DASHBOARD, INCLUDING THE TRACTION CONTROL OFF. THIS HAS SHUT DOWN MY CAR ON THE HIGHWAY SEVERAL TIMES SINCE 2016. WHEN I TOOK IT TO THE DEALERSHIP, IT WOULD RESET ITSELF AND THE CODES WOULD GO AWAY TEMPORARILY. THE DEALERSHIP RECOMMENDED TO CHANGE THE ENGINE CONTROL MODULE AND CABLES. I HAD TO GET TOWED OFF THE HIGHWAY AS THIS HAPPENS SO RANDOMLY. THE REPAIR SHOP SAYS THAT IT IS A MYSTERY TO THEM AS THEY HAVE CALLED THEIR GMC SPECIALTY TECHNICIANS FOR ADVICE. FINALLY, I WENT ONLINE AND STARTED A FORUM TO SEE IF ANYONE ELSE IS HAVING THESE ISSUES THAT NO ONE CAN SEEM TO FIX. THIS IS A KNOWN ISSUE SEVERAL SIMILAR STORIES 'CAR FORUMS/ GMC/ GMC ENVOY XL". I AM SURPRISED THIS IS NOT A RECALL AND SHOULD BE IMMEDIATELY. CHANGED SENSORS ON TIRES THAT WEREN'T THE ISSUE SINCE THE INDICATOR LIGHT STILL COMES ON. I HAVE PICTURES AND VIDEOS OF THE INDICATOR LIGHTS FLASHING AND THE CAR SHUTTING OFF. I AM NOT ABLE TO DRIVE MY TRUCK AS SOON AS IT IS TURNED ON ALL OTHE LIGHTS ARE FLASHING STABILITY LINK/ ENGINE/ AIRBAG/ BRAKES. IT IS RIDICULOUS CAN SOMEONE PLEASE CONTACT ME. THIS PROBLEM IS NOT ONLY WITH ME BUT SEVERAL OTHER WHO HAS DONE NOTHING WRONG.

PERSISTENT "TICKING" LIFTER UPON START OF A COLD ENGINE. SLIGHT LOSS OF POWER UNTIL THE ENGINE FINALLY WARMS AND THE TICKING SUBSIDES. THIS PROBLEM OCCURS IN BOTH WARM AND COLD WEATHER BUT IS WORSE DURING COLD WEATHER. WHEN I ASKED THE LOCAL GM DEALER ABOUT A SOLUTION, THEY DESCRIBED A POTENTIAL REPAIR; A BAFFLE MAY BE INSTALLED IN THE OIL PAN TO CORRECT THE PROBLEM OF OIL DRAINING OUT OF THE TOP SIDE OF THE MOTOR. THIS INDICATES TO ME THAT GM HAS RECOGNIZED A DESIGN FLAW IN THIS MOTOR (THE 5.3L WITH ACTIVE FUEL MANAGEMENT AND "FLEXFUEL" OPTION) THOUGH THE DID NOT OFFER TO PERFORM THE REPAIR FOR NO COST.

EXCESSIVE OIL LEAK WENT TO THE DEALER NUMEROUS TIMES, BUT THEY SAID IT WAS NORMAL TO LEAK A QUART BETWEEN OIL CHANGES. HAD NUMEROUS TESTS DONE AND THEY SAID IT WAS STILL WITHIN STANDARDS. I AM SORRY BUT I DON'T THINK THAT A QUART BETWEEN OIL CHANGES IS ACCEPTABLE. BEEN ONGOING FOR A WHILE AND I AM SURE IT IS LEAKING TWO QUARTS AND THERE IS A SEAL LEAKING NEAR THE OIL PAN. PRETTY SEVERE TO HAVE NOT BEEN FIXED BY THE DEALER IN THE BEGINNING. THEY WANT OVER $600 TO REPAIR THE LEAK NOW. *JS

WHILE PICKING UP MY CHILDREN FROM SCHOOL THE ENGINE STARTED BACKFIRING,PULLED THE CAR OVER AND PUT INTO PARK IDLE COMPLETELY UNSTABLE, TRACTION CONTROL SERVICE LIGHT CAME ON ENGINE LIGHT CAME ON. HARD SHIFT ON TRANSMISSION. TOTALLY DISAPPOINTED. TOOK IT TO THE DEALERSHIP FOR A DIAGNOSIS THEY SAY THE LIFTERS ARE BAD AND ARE NO LONGER COVERED UNDER WARRANTY. QUOTED ME 2700.00 TO REPLACE 2 LIFTERS SO NOT ACCEPTABLE THIS CAR DOES NOT EVEN REQUIRE A TUNE UP UNTIL 100000 MILES. EXPLAINED THAT TO THE SERVICE REP AND HE CAME BACK WITH A DIFFERENT QUOTE TELLING ME THEY WOULD BE WILLING TO COVER HALF. REALLY WHY WOULD YOU OFFER TO PAY HALF RIGHT OFF THE BAT. I BELIEVE THEY ARE AWARE THAT THERE IS A PROBLEM AND TRYING TO COVER IT UP. MY BROTHER IN LAW HAS A YEAR NEWER MODEL AND JUST HAD THE SAME ISSUE REPAIRED LAST MONTH. THEY ALSO PAID HALF FOR HIS. HOW IRONIC IS THAT. I DONT BELIEVE THE OWNERS OF THESE VEHICLE SHOULD BE RESPONSIBLE FOR A FAULTY PART ON AN ENGINE GM SHOULD BE! THERE ARE MANY POST ON THE INTERNET OF OTHER OWNERS EXPERIENCING SIMILAR PROBLEM THIS MOTOR NEEDS TO BE RECALLED. *TR

2007 YUKON XL - TRACTION CONTROL CAME ON CAUSING A REDUCTION IN POWER WHILE TRAVELING. THIS IS A SAFETY CONCERN THAT SHOULD BE ADDRESSED BY GENERAL MOTORS. THIS IS A VERY SERIOUS SAFETY ISSUE THAT NEEDS TO BE LOOKED INTO, BEFORE SOMEBODY GETS HURT OR KILLED. GM NEEDS TO RECALL THEIR PRODUCTS THAT ARE INVOLVED. *TR

ENGINE STARTED BY ITSELF WHILE CAR WAS IN THE GARAGE. ENGINE WAS RACING. GARAGE WAS EXTREMELY HOT FROM ENGINE RUNNING. KEY WAS IN IGNITION BUT PULLED OUT SO THE ALARM WOULDN'T DING. DOORS WERE NOT LOCKED (NEED TO BE LOCKED FOR REMOTE ENGINE START TO WORK). OPENED DRIVER DOOR, REACHED FOR KEYS AND THEY FELL OUT IN MY HAND AND THE ENGINE SHUT DOWN BY ITSELF. WE WILL TAKE THE CAR TO PIERCE DODGE/GM RONAN, MT FOR EVALUATION. *TR
