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. ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****761455.
