While driving at 65 mph, the Yukon just shut down and the battery light came on. Got to shoulder of road, put it in park, turn of the ignition and started it right back up. Did it again, 15 minutes later - same results. The next 7 times, the car at low speed (15-20 mph) started acting like it wasn't getting gas and running rough, not pulling. Pulled of road. Would turn over and try to start and if it started, was very rough. After about 15 minutes, the Yukon started like nothing was wrong and would run for 10-15 minutes. This also happened to me in June. Took to an independent mechanic who could find nothing wrong. Happened to my parents in 2006 in this vehicle traveling to mississippi. GMC dealer could find nothing wrong. Currently the dealer wants to change the fuel pump. I have researched and others with this problem have replaced the fuel pump and it doesn't stop happening. Speedometer just failed too. Wonder if it could be an electronics/electrical problem.
The needles for my speedometer and engine temp. Both sit in the 6 o'clock position and are completely inoperative. Speedometer has been broke since December of 2005 and the engine temp gauge broke October 2007.
2003 Yukon xl would die like it was out of gas when it still had at least 1/4 tank or it would not start when it had at least 1/4 tank of gas but if you added 1 - 5 gallons of gas it would start. Took to dealer and they said the fuel pump had low pressure and they replaced fuel sending unit. Seems to be fine now. Dealer stated they had not seen any other vehicles with this problem but I know of at least 4 other gm SUV's that are having the same problem in the small town that I live in.
The passenger side rear tire blew out while consumer was traveling at 60 mph. At 1,000 miles the vehicle's fuel pump failed while driving on the freeway at 65 mph.
2003 GMC Yukon denali xl engine stalled while driving. The fuel pump failed.
While driving 65 mph and pulling a trailer vehicle stalled. Prior to stalling there was some hesitation and jerking as if not getting fuel to engine. The dealer took vehicle to dealership in arizona, and fuel pump had to be replaced. This was the second occurrence for fuel pump problem. Also, experienced steering problem. The steering would be sticking, and it would jam when making turns either left or right. The mechanic at dealership had to replace a seal in column shaft of steering wheel. The light clunk noise in the steering, low voltage, and insufficient fuel pressure on aceleration intermittently.
I have a 2003 GMC Yukon. It now has 20,000 miles. Gm has had to replace the fuel pump twice so far and will have to every time I run low on gasoline. It seems that the pump is located in the gas tank and the pump depends on the tank having enough liquid to keep the electric pump cool. Otherwise it overheats and burns up. I can't believe such dumb engineering. I'm sure that I am not the only consumer who has had this trouble. The service people make no secret that you must keep at least a quarter tank at all times to keep the pump from burning up.
Complete loss of power on the highway while driving 65 mph. The dealer diagnosed the problem as a fuse and faulty fuel pump but could not gaurantee that the problem would not recurr.
When filling the vehicle with fuel a leak has developed underneath. Consumer has scheduled an appointment with the dealer.
