2003 Chevrolet Avalanche Owner Comments

problem #1

Apr 122004

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 6,000 miles


While driving my 2003 chev Avalanche down a hill I realized that when I stepped on my brakes, they went to the floor, the vehicle slowed down, but very slowly. I have towed my boat with this vehicle in the past and I thought that it was having a hard time slowing down. I'm affraid that if I have to stop quickly the brakes will not stop the vehicle in time. I am a state trooper and I am very familliar with the braking systems to include ABS. I only have 9000 miles on the vehicle and this shouldn't be happening. I took the vehicle to a local GM dealership for several repairs, I requested them to check the brakes. I was advised by the service mgr that the brakes were within GM specs. I asked him what that meant? he said that he had had a lady come in several weeks ago complaining of the same thing and because she wouldn't go away he contacted the GM engineers, they came out and inspected her brakes, they told him that her brakes were within specs and they wouldn't do anything. He then told me that my brakes were better than her's. I asked him what he meant by that, he said that if her brakes were ok then my brakes would be within specs. I told him that I wasn't satisfied with the way the brakes worked and that I wanted him to make a note of my dis-satisfaction. He never wrote this on my invoice. The second complaint is that I had advised the service department of a problem with the remote controled outside mirrors. They were not working the way they were designed. I was advised that it was operator error. I told them that I was very capable of reading and setting the operator preferences. I told him that this was the second time that the vehicle had been to a GM dealership for the outside mirrors not working properly. I have read on you service bulletin web site that their had been one issued for this type of problem. I am also having a problem with the alarm system, it doesn't set properly, they again advised me that it was operator error.
