Only reason I haven't switched-out their stuff in the past several trucks, is because I get a new one every four years.
If I decide to keep the 2014 Silverado I have now, may go with someone else's "permanent" anti-freeze?
This truck has the 5 year/100K power train warranty and they've dropped that with the 2016s. So I may hang onto it as long as that warranty is still good?
The extended factory warranty on all the stuff that croaks, like A/C, power windows, etc is good until 77K miles and 5 years. Used that once on the 2010, when the A/C compressor developed a slow leak. No deductible on that warranty, like there was on the 2006 Sierra.
Had to use that once also, for the fan switch and a noisy blower. $100 deductible on about $400 worth of repairs beyond the original 3 year coverage. Only other warranty work done was a new power steering box that leaked at about 29K miles, no charge.
Other than a new intake gasket and tailgate straps on the '02 S 10, that's it for warranty-covered stuff for the past four trucks and 13 years. Also got a new tire on the S 10: BFG T/A KO that had a heavy spot and couldn't be balanced.
So yeah, no major beef here with GM trucks and the '14 does 20 MPG or better on combined trip mileage. And it's a rocket on the road.
