SPEEDOMETER AND BRAKING LIGHTS FAILED WITHOUT WARNING WHILE DRIVING. ALSO VEHICLE WOULD NOT SHIFT ABOVE 2ND GEAR. DEALER DIAGNOSED THAT ELECTRONIC CONTROL MODULE(ECM) WAS FLOODED WITH GASOLINE DUE TO A DEFECTIVE LEAKING FUEL INJECTOR. DEALER RECOMMENDED THAT CONSUMER REPLACE ALL 8 INJECTORS BECAUSE THEY ARE EXHIBITING THE SAME POTENTIAL TO FAIL/LEAK.*AK HARNESS, CPI FUEL, METER, VCM, CORE RETURN, SEAL AND SWITCH ASSEMBLY WERE REPLACED. *TT

ENGINE AND ENGINE COOLING
I NOTICED AN APPROXIMATE 4'' CRACK ON MY DASH BETWEEN THE WINDSHIELD AND STEERING WHEEL HUMP. I THEN NOTICED A SIMILAR CRACK EMERGING NEAR THE TOP LEFT PORTION OF THE FRONT PASSENGER SIDE AIR BAG. I THOUGHT MAYBE THE EMPLOYEES WHERE I GET MY CAR WASH WERE APPLYING TOO MUCH PRESSURE. HOWEVER, AFTER LOOKING ONLINE TO BUY A NEW DASH, I FOUND THAT I WAS AMONG MANY GMC OWNERS THAT HAVE THE SAME ISSUE. I DONT THINK IT IS A COINCIDENCE THAT WE ALL HAVE THE SAME CRACKS, IN THE SAME LOCATION ON THE DASH. ALSO, THE CHROME PLATING ON BOTH MY DRIVER AND FRONT PASSENGER INNER DOOR HANDLES IS PEELING OFF. I HEARD THAT EXPOSURE TO THE SUN MAY BE A CAUSE, HOWEVER, MY TWO FRONT WINDOWS HAVE HAD 5% TINT ON THEM SINCE I BOUGHT IT. ALSO, I JUST GOT MY VEHICLE BACK FROM THE DEALERSHIP BECAUSE OF CHECK ENGINE LIGHT ISSUES. THE PROBLEM IS FIXED FOR NOW, HOWEVER, AFTER RESEARCHING ONLINE IT SEEMS LIKE THERE ARE HUNDREDS OF GMC YUKON OWNERS EXPERIENCE VERY SIMILAR ISSUES WITH THEIR VEHICLE'S ENGINE. I KEEP READING ABOUT THE "REDUCED ENGINE POWER" AND "SERVICE STABILITRAK" WARNINGS. *TR
