| 2003 gmc yukon awd w/ stabilitrak. 40,000 mi.: when accelerating from a stop, the traction active dash display will very often come on, the powertrain disengages and i have to let up on gas until transmission re-engages. this has been occurring since september, numerous times a day. i have almost been rear-ended, since the drivers behind me presuppose i will continue accelerating. a gm dealer, after exam & diagnostics, could find no problem, even after being advised about possible wheel corrosion. in the meantime of course, it continues. an entry in edmunds car space has referred me to document id#1819672 202 gmc truck gmc k sierra 4wd; subject: product safety - front wheel speed sensor corrosion #05068b - (04/21/2006). this seems to be a dangerous, serious problem which should merit a recall. *jb | |||

| Dt: the contact stated when making turns there was a screeching noise coming from the rear of the vehicle. in snowy conditions when the four wheel drive was engaged there was difficulty driving followed by another screeching noise when shifting from automatic to four wheel drive. the vehicle has been to the dealer for inspection. the dealer overhauled the four wheel drive, but noted all four tires were off balance and varied in size. this could possibly be the culprit of the screeching noise when turning. the tires have not been replaced. *ak | |||

| We purchased a 2003 gmc yukon. before it had reached 3000 miles the neutral light came on on the 4x4 unit. from there it would shift itself into 4 low. we have had it into the dealer a total of 6 times now and they have replaced one of the components 3 times, two of the other components once. after the secon d replacement it started showing neutral again on the 4x4 unit. it seems as though the problems do not arise until after 1000 miles. the dealership service department told me that they have had a lot of problems with these units. we are trying to do a buy back but gm is dragging things out and giving us a hard time.*ak | |||
