I wanted the 6.2L L86 but it's not offered in the Tahoe chassis (yet)! Same engine in the Silverado/Sierra, anyone have any issues with them or the SUV platform?

Littleguy Posted September 10, 2015 Report Share Posted September 10, 2015 Good engines, but I don't like the displacement on demand. Since you are local... Quote Link to comment Share on other sites More sharing options...

POS VETT Posted September 10, 2015 Report Share Posted September 10, 2015 I love that engine. It has been fed E85 so far because I hate the way the engine behaves on 93-octane gasoline. AFAIK, the FFV part is no longer available for '16 model year. Quote Link to comment Share on other sites More sharing options...
Cordell Posted September 10, 2015 Report Share Posted September 10, 2015 Haven't had any real issues with the engines yet. I like the trucks, most of the issues I've delt with have to do with the infotainment not working right. They have some issues with the seat coushins moving, and a few trim parts, but overall nothing that has been much to fix. Quote Link to comment Share on other sites More sharing options...
