My 2008 4.8 (build date 12-2007) has been in the shop maybe 5 times over five years for items covered under warranty and extended warranty.

Some major stuff but mostly electronic related. The only mechanical issue I remember was leaking hose fittings on the transmission. I hope the electronic gremlins have been dealt with as I am at 103K miles.

I suspect at some point I will be paying for something expensive. BTW, my indie says the shocks and struts on this bad boy are $1K each.

They usually last until about 150K miles he says.
