| My parking/emergency brake goes all the way to the floor and does not hold my vehicle on even the slightest grade. the dealer states that this is normal per gmc even though they have had numerous complaints. my engine has a knocking noise when i start it up in the morning. the dealer also stated that this is normal per gmc. my front passenger bucket seat back moves forward and back (wobbles). my rear end wheel bearing were replaced because of a loud hum. that was misdiagnosed twice by alfred mathews. my front end feels loose and squeaks when accelerating or braking. rear leather bucket seats rattle all the time when driving and the leather has ripped @ seams twice. alfred mathews replaced once and tried unsuccessfully to fix seat rattle. my newest complaint is a noise that comes from the rear of the vehicle when you shut the doors. *jb ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****761455 | |||

| Two other people have told me their wheel bearings have failed. also with low mileage. these are shielded bearings that do not require lubrication. bearing on my truck was half gone when they replaced it. it was mis diagnosed by j.p. thibodeaux gmc in new iberia, la. and correctly diagnosed by courtesy gmc of lafayette, la. i had made two trips to j.p. thibodeaux complaining about the noise and wheel locking up. i was told it was a wheel sensor, causing the problem. told to drive truck home which was approximately 20 miles each way at 70 mph. this was very unsafe and dangerous knowing what i know now. these bearings are defective and need to be replaced by a quality bearing.*ak | |||
