Recently, my check engine light came on in my 2006 Yukon denali xl w/ a 6. 0 engine. The diagnostic test showed a gas cap problem. However, this did not fix the issue. Several weeks later, the engine started making what sounded like a clicking sound. Upon further investigation, it was discovered that there was a leak in the driver's side exhaust manifold. While in the shop, the mechanic discovered 2 bolts that were broken on the driver's side and it was found that one of the bolts on the passenger side is broken, but the passenger side exhaust manifold was not yet leaking. The auto shop was able to extract one of the bolts, but has found it impossible to remove the other on the driver's side without pulling the engine. This is a necessary repair because improper exhaust is a direct violation of epa standards. Furthermore, engine fires can result from this type of issue. Upon further research, I have found numerous other gm vehicle owners with a similar exhaust manifold bolt problem. In fact, there is a video created by carquestions on this exact issue. .

On June 12, 2008 had my oil changed and was informed that my front pinion seals were leaking on my 2006 Yukon. On June 13, 2008 I had them service at my local midas dealer. On June 18, 2008 I blew my front axle out pushing the transmission fluid out taking 4th gear out of my transmission. GMC has my Yukon now repairing @ $4,000. 00 claiming midas is at fault and midas is claiming GMC is at fault.
