There are 2 owner-reported fuel system complaints for the 2016 GMC Yukonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
THE fuel pressure line from the fuel pump to the flex fuel sensor chaffed a pin hole leak near the front top of the fuel tank. This caused a significant fuel smell and trace leak at the front of the fuel tank which could lead to a fire or explosion. The new hose has a longer chaffing covering leading me to believe gm knew about this issue. vehicle has 127,000 miles. I feel gm should reimburse me for this repair as a fuel line should not have ever chaffed through and leaked.
YUKON HAS 27,855 MILES ON IT AND THE FUEL INJECTORS HAVE GONE BAD AND STALLS WHILE DRIVING. IDLES ROUGH AND WHEN ACCELERATING THE YUKON JOLTS. COST IS $2,200 DEALER IN CHANTILLY VA. CHECK ENGINE STATES THAT THE VEHICLE MISFIRES BASED ON DEALER'S DIAGNOSTIC. NO WARRANTY TO COVER THE VEHICLE. OTHER COMPLAINTS OF OWNERS EXPERIENCING THE SAME SYSTEMATIC FAILURES OF THE FUEL INJECTORS AND THERE IS BACK LOG FOR THE PART. NOT SURE HOW A LOW MILEAGE VEHICLE WOULD NEED TO REPLACE FUEL INJECTORS WITH LESS THAN 30,000 MILES. OTHERWISE THE VEHICLE IS IN EXCELLENT CONDITION. *TR
