2004 GMC Yukon Denali Driver assistance Problems

FIRST THE AIRBAG WARNING LIGHT CAME ON. THIS HAS BEEN AN ONGOING ISSUE SINCE 2008. MY SPEEDOMETER REGISTERED THE WRONG SPEED. MY SETTINGS FOR THE SEAT AND MIRRORS QUIT WORKING OVER TIME.HOT AIR WOULD COME OUT OF MY VENTS WHEN THE AIR CONDITIONER WAS ON RANDOMLY. RADIO, NAVIGATION, HEAT, AIR CONDITIONER AND MIRRORS WOULD TURN ON/OFF RANDOMLY WITHOUT TOUCHING CONTROLS. THE LAST 3 YEARS WENT THROUGH 3 BATTERIES IN 3 YEARS. TESTS SHOWED AT LEAST 5 THINGS ARE ACTIVELY DRAINING BATTERY IN THE FUSE BOX. ISSUES HAPPENED MOSTLY WHEN CAR WAS ON BUT MIRRORS WOULD RANDOMLY MOVE WHEN CAR WAS NOT ON, VERY CREEPY.

THE "STABILITY CONTROL DISABLED" SENSOR COMES ON FOLLOWED BY "REDUCED ENGINE POWER" AND MY VEHICLE WON'T GO FASTER THAN 5MPH. THIS HAS HAPPENED AT LEAST 6 TIMES IN THE PAST SEVERAL MONTHS ONLY UPON START UP OF THE VEHICLE. SOMETIMES, IF I WAIT A COUPLE OF MINUTES AND RESTART MY CAR, IT'LL START JUST FINE BUT THE CHECK ENGINE LIGHT COMES ON. I FIRST BROUGHT IT INTO HENDRICK CHEVROLET ON 10/15/12. THEY CHARGED ME ALMOST $700 TO REPLACE "APP SENSOR ASSEMBLY". THEN I BROUGHT IT IN AGAIN ON 11/6/12 FOR THE SAME ISSUE. THEY REPLACED THE "CONNECTOR AT THE THROTTLE BODY" AND CHARGED ME $223.09. THE ISSUE TEMPORARILY WENT AWAY. I THEN BROUGHT IT BACK ON 12/20/12 WITH THE SAME ISSUE BUT THIS TIME THE CHECK ENGINE WON'T TURN OFF AS A RESULT OF THE REDUCED ENGINE POWER-STABILITY CONTROL DISABLED WARNING. THEY SIMPLY RESET THE WARNING AND THAT WAS IT. TIL THIS DAY, I CONTINUE TO HAVE PROBLEM WITH THIS VEHICLE GOING INTO REDUCED ENGINE POWER/STABILITY CONTROL DISABLED. THIS HAS BECOME A CONSTANT ISSUE AND THORN ON MY SIDE AND EACH TIME I BRING IT IN FOR SERVICE, THEY ALWAYS TELL ME IT'S SOMETHING ELSE. I HAVE READ MANY OF THE SAME ISSUES OTHER OWNERS HAVE HAD. WHY HAVEN'T THERE BEEN A RECALL ON THIS??? *TR

WHILE DRIVING ON INTERSTATE TRACTION CONTROL LITE CAME ON IN DASH THEN POWER TO SUV WAS LOST THEN ELECTRONIC MESSAGE READ OUT STATED "STABILITY CONTROL DISABLED " THEN " REDUCED ENGINE SPEED" MESSAGE APPEARED. I WAS ABLE TO PULL OFF INTERSTATE BUT NEARLY GOT REARENDED HIT BY SEMI. ENGINE WOULD RUN ONLY AT IDLE SPEED. AFTER SHUTTING OFF VEHICLE AND WAITING MINUTE OR TWO THEN RESTARTING IT RAN FINE. THIS HAS HAPPENED NUMEROUS TIMES SINCE THEN. SPEEDS VARY 70,55,40 MPH IT DOESN'T MATTER. AFTER CALLING DIFFERENT GMC DEALERS ABOUT PROBLEM THEY ACT LIKE THIS IS SOMETHING THEY NEVER HEARD OF."BULL**** !!!!. ITS THE SAME PROBLEM NUMEROUS GMC OWNERS ARE FACING ON THE INTERNET. GMC CUSTOMERS HAVE SPENT THOUSANDS OF DOLLARS WITH NO PROBLEMS SOLVED. ALL THEY WANT TO DO IS HOOK YOU UP TO ELECTRONIC MACHINE AND OVERCHARGE YOU FOR THE SAME THING AUTOZONE ,ETC. BUSINESSES WILL DO FOR FREE. I DON'T HAVE THOUSANDS OF DOLLARS FOR THEM TO BE PARTS REPLACERS . GMC SHOULD KNOW THE EXACT PART TO FIX THIS PROBLEM. SOMEONE OR FAMILY IS GOING TO GET HURT BADLY IF GMC DOESN'T FIX THIS PROBLEM THEY KNOW THEY HAVE. *TR

WHILE IN THE MIDDLE OF DRIVING, THE "STABILITY CONTROL DISABLED" SENSOR COMES ON FOLLOWED BY "REDUCED ENGINE POWER" AND MY VEHICLE JUST SHUTS OFF. I HAVE BEEN FORTUNATE THE 4-5 TIMES IT HAS HAPPENED AS I HAVE BEEN ABLE TO PULL OFF THE ROAD, WAIT A COUPLE OF MINUTES AND RESTART MY CAR. I HAVE ALREADY REPLACED A HUB THAT MY MECHANIC SAID WAS CAUSING A "TRACTION CONTROL" PROBLEM FROM EARLIER. I AM READING ONLINE ALL OF THE NIGHTMARES AND I UNFORTUNATELY DO NOT HAVE THOUSANDS OF DOLLARS TO KEEP TRYING TO FIX AN ISSUE THAT GMC IS CLEARLY AWARE OF. I HAVE 5 KIDS AND FREQUENTLY DRIVE THEM AROUND AND SOMEONE IS GOING TO GET HURT AND I THINK GMC SHOULD TAKE SOME RESPONSIBILITY. *TR

2004 GMC YUKON XL DENALI SYSTEM STABILIZATION DISABLED WARNING LIGHT INTERMITTENTLY COMES ON. THE DEALER CANNOT REPAIR THIS ISSUE BECAUSE THERE ARE NO DIAGNOSTIC CODES IN THE CAR COMPUTER. I HAVE TAKEN THE TRUCK TO THE DEALERSHIP WITH THE WARNING LIGHT ON, BUT STILL NO ERROR CODES. ONSTAR RUNS DIAGNOSTICS AND REPORTS NO ERRORS AND TELLS ME TO DRIVE TO THE NEAREST DEALERSHIP BECAUSE THE VEHICLE IS UNSAFE. THIS FIRST OCCURRED IN DECEMBER WHILE THE TRUCK WAS STILL UNDER WARRANTY, NOW SEVERAL TRIPS TO THE SERVICE SHOP AND IT STILL IS COMING ON. I AM WORKING WITH GMC CUSTOMER SUPPORT TO TRY TO RESOLVE THE ISSUE, BUT TO DATE THEY ARE SAYING THEY CAN'T FIX IT BECAUSE THERE ARE NO DIAGNOSTIC CODES. I HAVE ASKED THEM IF THE TRUCK IS SAFE TO DRIVE WITH WARNING LIGHT ON, BUT THEY CANNOT ASSURE ME THAT IT IS. THEY REFUSE TO DOCUMENT ANYTHING IN WRITING ABOUT THE SAFETY OF THE TRUCK. TO DATE THERE HAVE BEEN NO ACCIDENTS NOR INJURIES, BUT I HAVE LOST ALL CONFIDENCE IN THE VEHICLE AS I WAS TOLD THE STABILIZATION SYSTEM WAS MANDATED BY THE GOVERNMENT AND IT MUST BE OPERATIONAL. WHAT RECOURSE DO I HAVE TO INSURE THE TRUCK IS SAFE? WHY CAN'T THEY REPLACE COMPUTER MODULES UNTIL THERE IS A RESOLUTION? THE TRUCK DID NOT DO THIS FOR THE FIRST 35 MONTHS I OWNED IT, DRIVING THE SAME EXACT ROADS THAT THE WARNING FLASHES ON NOW. *TR

FIRST MY OIL GAUGE STARTED GIVING FALSE READINGS ON MY 2004 GMC DENALI, I COULD LIVE WITH THAT. THEN MY SPEEDOMETER READINGS ARE ALL OVER THE PLACE...ALL THE TIME WITH DIFFERENT READINGS. I AM SCARED FOR MY SAFETY AND THE SAFETY OF OTHERS. FROM READING ONLINE THIS IS A VERY COMMON PROBLEM ON GMC VEHICLES AND I FEEL SOMETHING SHOULD BE DONE BY GMC TO REMEDY THE PROBLEM!!! *NM
