2004 GMC Yukon Owner Comments

problem #2

Apr 262005

Yukon 8-cyl

  • Automatic transmission
  • 500 miles


The problem I'm having is a horrible bubbling or gargling sound emmiting from my 2004 Yukon exhaust. It sounds really bad, enough to turn peoples heads while I'm sitting at the conveneience store or a drive thru. The dealer in which I bought it from states that they all make this sound, but I'm not stupid. I know others with the same make and year model and they do not have this problem. I just want it fixed. If I'm willing to pay $44,000 for a vehicle I expect it to look and sound great or at least look and sound like a new one. Please help!

Yukon 8-cyl

  • Automatic transmission
  • 500 miles
When my 2004 GMC Yukon warms up, a loud repetitive clanging noise eminates from the exhaust system. This can be heard while driving and continues for a period after the vehicle is turned off. The Yukon was purchased new on 5/31/04 and began making the noise within 500 miles. GMC says engineering has been working on the problem since 11/03 and it involves metal in the exhaust system being deformed by the heat. I have spoken with several other Yukon owners and made a point to listen to other Yukon on the road and have not found another Yukon exhibiting the same problem. GMC refuses to replace the exhaust system. If the metal is deformed, how do I know that it is not leaking fumes into the passenger compartment?
