Well, I took the Yukon in for an oil change and inspection yesterday, about one week after purchase. After a thorough inspection, we found the lower ball joints to be bordering on unsafe, the driver side front sway bar link end is missing, and the rear axle seals are leaking. If I had purchased the truck from anyone off the street, I would expect a few things to be "undisclosed" for the sale, just so the guy could get rid of it.... but I bought this from a dealership. The guy has the standard dealer inspection sheet on the truck, with everything marked as "good" or "legal", and no mention of any of the problems I listed above. In Wisconsin, dealer inspections have to be done by a certified mechanic/ASC Certified shop. In this case, I'm not sure of the guy's qualifications, but he's the dealer's "friend". The Records Inspector (the guy that signs off on the inspection sheet after the inspection) is the dealer's brother. The truck was sold to me "As Is", but I was assuming that everything on the inspection sheet was accurate when I agreed to the "As Is" condition. Like I said, if it were some jackass off the street selling his truck, I wouldn't care, but this is a dealership, so what do you guys think I should do? There's a Lemon Law in Wisconsin, but I don't know if it applies to used (1994) vehicles, or only newer vehicles. I am thinking of just going to the guy, showing him his inspection sheet and my inspection sheet, and telling him he's gotta pay for at least the labor for getting these things fixed, since they were obviously existing problems. Need your suggestions, thanks guys.
