2003 GMC Yukon Xl Problems

Odometer Fraud. The contact purchased a 2003 GMC Yukon XL. It was later discovered that there was a mileage discrepancy. The vehicle was a dealer sale on January 26th, 2026. At the time of purchase and at the time of the vehicle registration, the vehicle mileage was 186,000. While applying for insurance on February 20, 2026, the contact was informed that the vehicle was due for a 300,000-mile maintenance plan. The contact confirmed through the Carfax Report that the actual mileage was 300,000. The dealer was contacted and informed of the odometer fraud discovery; however, the dealer refused further contact to resolve the issue. The odometer fraud was also reported to the State Consumer Protection Division.

TL* THE CONTACT OWNS A 2003 GMC YUKON XL. THE CONTACT STATED THAT WHEN THE KEY CHAIN WAS ATTACHED TO THE KEYS, THE VEHICLE FAILED TO START HOWEVER, WHEN THE KEY CHAIN WAS REMOVED, THE VEHICLE START AS DESIGNED. THE VEHICLE WAS NOT TAKEN TO A DEALER NOR AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 220,000.

BRAKE FAILURE DUE TO LEAK FROM RUSTED OUT BRAKE LINE UNDER DRIVER SEAT AREA AND LOSS OF BRAKE FLUID.

THE BRAKES FAILED WHILE DRIVING ON A CITY STREET CAUSING MY VEHICLE TO NEARLY STRIKE A NUMBER OF CHILDREN AT A CROSSWALK. AFTER EXAMINATION BY A MECHANIC, IT WAS DETERMINED THAT THE BRAKE LINE HAD CORRODED AND BURST UNDER PRESSURE. I HAVE RECEIVED NO NOTICE OF THIS POTENTIAL FAILURE FROM GMC EVEN THOUGH IT HAS BEEN INVESTIGATED BY THE NHTSA. SHOULDN'T THE MANUFACTURER HAVE AN OBLIGATION TO REPAIR THIS POTENTIALLY LETHAL PROBLEM? AT A MINIMUM I FEEL THAT GMC AND/OR THE NHTSA HAVE A MORAL OBLIGATION TO NOTIFY OWNERS OF AFFECTED VEHICLES THAT THEY ARE DRIVING A POTENTIALLY DEADLY VEHICLE.

WE PURCHASED OUR YUKON OUT OF THE SHOWROOM. IT HAS QUAD STEERING, A FEATURE WE PAID EXTRA WITH THIS VEHICLE. ABOUT A WEEK AFTER WE HAD THE VEHICLE, THE QUAD STEERING WOULD DROP OUT OF QUAD MODE AS INDICATED BY THE LIGHT ON THE DASHBOARD, AS WELL AS THE FEEL OF THE DRIVE, AND ON OCCASION NOT LOCK INTO POSITION EITHER. THE WHEELS WOULD THEN TURN SIDEWAYS AND WE TEMPORARY LOSE CONTROL OF THE VEHICLE UNTIL WE PULL OVER TO STRAIGHTEN OUT THE WHEELS IN ORDER TO LOCK THEM IN POSITION. WE'VE SINCE HAD THE VEHICLE INTO THE DEALERSHIP ABOUT 5 OR 6 TIMES WITH THE SAME COMPLAINT. THE DEALERSHIP HAS ATTEMPTED TO REPAIR ON MANY OCCASION, HOWEVER IT CONTINUES TO BE UNRELIABLE. WE ARE VERY CONCERNED THAT THIS VEHICLE IS GOING TO CRASH SOMEDAY BECAUSE OF THIS PROBLEM... OF WHICH IS UNEXPECTED AND DANGEROUS. AFTER GREAT CARE OF THIS VEHICLE, FAILURE OF THE QUAD FEATURE CONTINUES TO BE A SERIOUS UNRESOLVED DEFECT. THE IMPACT ON OUR SCHEDULE TO DROP THE VEHICLE OFF FOR SEVERAL DAYS, RENT A CAR, AND STILL HAVE NO SOLID REPAIR IS VERY UPSETTING AND BECOMING A HARDSHIP. *TR

AT 32,652 THE INTERMEDIATE SHAFT HAD TO BE REPLACED. WE HAVE HAD LOTS OF PROBLEMS WITH THIS VEHICLE AND HAVE NOT OWNED IT FOR A YEAR! BETWEEN THE MONTHLY TRUCK PAYMENTS AND REPAIRS WE COULD HAVE PUT A NICE DOWN PAYMENT ON A SECOND HOUSE AND KEPT THE RELIABLE TRUCK WE TRADED THIS ONE FOR!!*JB

THERE WAS A LOUD NOISE COMING FROM THE LEFT FRONT WHEEL - ONLY WHILE DRIVING AT HIGHWAY SPEEDS. THE DEALERSHIP REPLACED THE LEFT FRONT HUB AND BEARING FOR $550. *TR

WHEN THIS HAPPENS THE ENGINE POWER IS SHUT OFF IMMEDIATELY AND THE ENGINE WILL ONLY IDLE. THIS IS A KNOWN ISSUE WITH GM AND IS A POTENTIALLY EXTREMELY DANGEROUS SAFETY ISSUE. THE ENTIRE TAC SYSTEM ( THROTTLE BODY, TAC MODULE, PCM, WIRE HARNESSES/CONNECTORS) NEEDS TO BE INVESTIGATED.

VEHICLE STALLS WHILE IN MOTION. FIGURED OUT IT MAY BE RUNNING OUT OF GAS DUE TO THE GAUGE NOT WORKING. NOW, IT STALLS WHEN IT ONLY HAS A HALF A TANK OF GAS, NOT COMPLETELY EMPTY. PUT 16 GALLONS OF GAS IN THE 30 GALLON TANK, TRUCK RUNS SMOOTH. REPLACED THE FUEL FILTER TWICE. REPLACED THE BATTERY, TESTED THE ALTERNATOR, RESULTS NO ALT. PROBLEM. CHECK ENGINE LIGHT ON, SPEEDOMETER IS OFF, GAS GAUGE IS OFF, AND THE REAR VIEW MIRROR DISPLAY LIGHTS GO ON AND OFF ERRATICALLY. BIGGEST PROBLEM IS WHEN I BREAK THE TRUCK WILL SHUT OFF. THIS HAS BEEN GOING ON SINCE NOV. 2010, WHEN WE REPLACED THE BATTERY AND QUIT USING A CERTAIN TYPE OF GAS IT SEEMED TO BE FINE. NOW, IT IS ACTING UP AND TODAY WAS THE FIRST INCIDENT SINCE EARLY DECEMBER. *TR

SHOCKS ARE IN A MAINTAINED PRESSURE TO WHICH THE VEHICLE IS OPERATED IN A FIRM PRESSURE MAKING A SOLID RIDE AS IF THE VEHICLE WOULD BE IF IN TOW MODE.NOT SURE IF THE CHARACTERISTICS OF THE HANDLING ARE EFFECTIVE.

I HAVE A GMC YUKON AND THE WHEEL BEARINGS IN BOTH SIDES HAVE WENT OUT. I HEARD THAT THE H2 HUMMER HAS A RECALL ON ITS WHEEL BEARING. HOW COME THE YUKON DOESN'T? I HEARD OF OTHER YUKONS HAVING THE SAME PROBLEM. IS THIS A CHEVY PROBLEM? MY WHEEL ALMOST CAME OFF OF MY VEHICLE GOING DOWN THE HIGHWAY. THE MECHANIC SAID THE ONLY THING THAT WAS KEEPING IT ON WAS THE BRAKE CALIPER. I SURE HOPE NOBODY GETS HURT OVER SAVING A COUPLE OF DOLLARS, PLEASE THERE NEEDS TO BE A WARNING AND POSSIBLY A RECALL FOR THIS PROBLEM. *TR

THE TENSION OF THE DRIVER SIDE BUILT-IN-SEAT SEATBELT CAUSES PAIN IN LEFT SHOULDER EVEN AFTER A SHORT DRIVE. I CHECKED THE TENSION IN ANOTHER GMC CAR AND IT APPEARS TO BE THE SAME.
