| When accelerating from a stop the transmission reacts as if in neutral. after a few seconds, it drops into gear. since no codes show up when the car is taken in for repair the dealer will not acknowledge there's a problem. this is a severe safety hazard that could result in an accident if the driver is attempting to cross a roadway, mover over railroad tracks, etc. the vehicle doesn't move when the accelerator is applied. dt | |||

| Automatic transmission lunges forward and vibrates when shifting from first to second gear. dealership has examined vehicle to determine the cause of problem. *ak *yh | |||

| Transmission problem: at 40 mph going downhill unknowingly went into neutral and accelerating to maintain speed went over 3000 rpm. normally at that speed 1400 rpm. transmission bolt missing. found by owner after dealer performed oil change. no paint scratched where bolt would have been if there was a bold there from manufacturer. dealer replaced bolt at no charge. hot front brake left side & tire feels hot - noticed by smell from left side - right side front no heat or smell. found after traveling 60 mph and wheel & tire hot to touch. dealer examined all brakes, claimed all normal, even brake pad wear on all brakes and found no abnormal conditions, but no problem since they dealer looked at this.*ak (tiresize: 265/16)( dot number: tire size: 265/16 ) | |||

| Original transmission was slipping and truck going into a neutral while on highway, took to dealer and they kept it 11 days had to replace entire transmission. now, aprx 6 weeks later truck is again not shifting right, put in reverse from parked position, press accelerator and the truck slams into gear. when in drive from parked position accelerate and it revs and revs and finally slams into drive then intermittently while driving goes in & out of gear. pretty disgusted for a xmas gift at $45,000.00 never expected this. *ak | |||

| My 2000 yukon has had problems with the engine stalling during braking and turns since i bought it in 2001 with 10,000 miles on it. i took it in to the dealership several times while still under warranty and i was given the run around. the problem is now severe and has almost caused me to crash more times than you and i have fingers and toes. i cannot trade this vehicle in because of this problem nor can i find a mechanic or dealership (ha ha ) that can find out where the problem lies. i have been told that the intake motor or the intake gasket need to be replaced but diagnostics cannot back these theories up. today i nearly hit a telephone pole because the vehicle died and lost power steering while i was making a turn. *ak | |||

| Purchased vehicle used from mei auto brokers 407 834 6244 on 11/06/01 took vehicle to courtesy gmc 407 767 2070 on 11/08/01 spoke with dave junkins ext 1236 . dave told me that the driveshaft was unbalanced and that caused the shaking at speeds greater than 45 mph. he also stated that it was a manufacturing error and that it was like that(unbalanced w/ shaking ) since manufactured i am deeply concerned that this driveshaft shaking and vibrating since new has caused damage to either the transmission or differential and subsequent failure is imminent. to this date 11/20/01 i am still awaiting word from dave at courtesy on when a new part will arrive and repairs will be preformed. | |||
