 Consumer stated the vehicle would leak diesel fuel into the oil, and overflow when the injectors stuck open. the problem happened 14 times. vehicle would go into limp mode, and would reach certain rpms when this happens.*jb

 State inspection, failed due to rotted fuel filler neck. was told for awhile it was due to gas cap, replaced that, light would go on and off. when it would no longer go off took back to dealers. dealership replaced fuel filler neck, along with valve/sensor at a cost of over $500. gm will not help as they claim it was due to environmental factors (we live in ma). also, parking brake backing plates rusted out, e-brake cables frozen, had to replace those at another $850. old parts not available, dealer repaired. *tr

 When the air conditioner (a/c) is used it takes at least eight minutes for the cool air to flow. there is a foul odor coming from the vents that smells like rotten eggs. also, consumer is concerned with the sound of the engine. although the vehicle is equipped with a gas engine, it sounds like a diesel engine. there is a irritating noise that occurs intermittently at any speed. the dealer claims that the noise is normal. *ak engine burns 3 qts. of oil every 3000 miles and the fuel gauge isn't accurate. *ph *nlm

 I recently purchased a 2001 gmc sierra,the first tank of fuel that was put in the fuel gage jumps from full to empty, it has continued to do this until the current date, i have several people i have talked to in my area with same vehicle with different years 1999-2002, experiencing same problem, was told by mechanics that it is the fuel sending unit, have talked to people who's vehicles have shut down because of it, should be a recall on this problem,very unsafe!*jb

 Many problems: 4 wheel drive sensor, front end suspension, parking brake, service brakes, anti-lock brakes, speed sensors, radio, center console, engine noise rapping when starting, tailgate cables, anti-theft sensor, and now the battery voltage gauge needle excess dropping when stopping, engine idling to low when stopping. dealer says problem is normal. let's test drive a new truck and show me it is normal. this truck is a lemon in my eyes!*jb

 Fuel gauge has never worked properly( jumps from 1/2 tank to empty) today i was drive on ! 40 east at the posted speed of 75 mph with 1/2 tank of fuel and the vehicle just shut down, i did get safley to the shoulder, to find i was out of fuel ...i t read 1/2 tank previously i had heard of this happening to other gmc owners in this area but it was their fuel pumps. the dealer says it is the local refinery's falt for additvies in the fuel .. and this is the only area where the fuel system is being affected. my employeer had 2 fuel pumps put in her new gmc yukon in 6 months, at her expense. i do not want to pay for defective parts or an vehicle that is unsafe for the intersate.

 After fuel pump was replaced, the vehicle wouldn't start. *ph while the vehicle was under warranty, it would not start. the fuel pump was changed but not the connector. the problem resurfaced and quit running numerous times. the service dealer stated that the fuel cap was not tight enough which caused this problem. (the cap was tightened) the vehicle stopped running while at a traffic light more than once. the consumer had taken the vehicle to the dealer and had to pay for repairs because the vehicle was then out of warranty. several weeks later the problem recurred and the service dealer found no gas pressure and replaced the pump. the vehicle stopped again while the consumer was making a left turn. the consumer had taken upon himself to go under the vehicle and wiggled the wiring harness which started the vehicle. the service dealer changed the fuel pump connector harness. (the connector was burned and pitted) *sc *jb

 Fuel gauge has been malfunctioning for several months now - sometimes works properly, but other times reads empty when tank is full, reads more fuel than in tank, etc. i have several friends who have this generation of gm full-size truck (gmc sierra, chevy silverado, gmc yukon, chevy tahoe - gmt800 series), and most of them have the same problem. i am told that the issue is with the fuel sending unit. *jb

 Dt*: the contact stated while driving any speed, the gas gauge goes up and down, and the fuel light flashes. the dealership determined the fuel sending unit needs to be replaced.

 My gas gauge dances constantly or just stays on empty with gas gauge always on gmc sierra 2001. sometimes it shows the gas level correctly for about 30 minutes after getting gas then it moves around or goes to empty even though it is not empty. *jb
