Interesting
My brother and my dad BOTH had to replace the intake manifold gaskets on their Yukon Denali and Suburban respectivly at $1000 a pop. Both were 6L V-8 engines with less than 50k miles on them.
My brothers Denali intake gaskets crapped out a second time a few months later and he got pissed and traded it in for a Tundra crew cab. Said it was his last GM vehicle.
Pretty sad when my Dad is retired from GM and my sister works for them and they are the only ones in my family that will by a GM product.
I went Ford Truck 21 years ago and also have a Toyota Tacoma that my wife inherited. I've had too many problems with Chebys and my brother has Tacoma and a Tundra and is looking for an Excursion w/ 7.3 Diesel because he needs more seating than the Tundra can offer.
