I have been completely unable to drive my 2007 gmc envoy at 33000 because my car makes the loudest noise when I cut the car on and when I accelerate it gets louder. I heard it first in the front of the vehicle on the drivers side. Called the dealer and they state its the idler pulley....Oh really well when my gas tank meter stopped reading and when I was unable to steer my car from a bad wheel bearing in september and october how come yall didn't fix it then. Or when I came in for the GMC oil change in september and received a 27 point check why wasn't it discovered then. Every month I came in I paid at minimum 300 dollars all way up to 500. Since I am the single owner of this vehicle and regularly get all my maintenance from GM dealers why is this happening. So now I have an appointment on Monday for the idle pulley and whatever else they tell me is wrong with the car. I bought a new car so I would have a reliable vehicle and unfortunately GMC let me down. I am terrified to drive this car. All this stuff has happened to me as soon as my car went over 30,000 miles and out of warranty. Shame on GMC for causing a hard working consumer and graduate student so much trouble!
