Hey everyone! Just found this while on the web so decided heck, a bunch of people with the same vehicle (and maybe issues) as me! I own a 2011 Tahoe LT and am the third owner. The SUV is coming up on 150k just having had my third oil change done since taking ownership. I've had only a firing issue at the throttle body but I cleaned out the intake and around the problem area and no issue since! About to purchase my first set of tires (Goodyear Wrangler DuraTrac). Regular upkeep at this millage to come but I love this thing. It is the envy of my friends and the perfect vehicle for road trips. Quality, class, and functionality at its best!
