I've been a fan of CHEVY since my first car (68 Chevelle). But this Suburban has shaken my faith in the most reliable engine, the 350, ever built. First problem with the transmission at 10k miles, gear replacement. Then 4-wheel drive issues, when in 4-wheel HIGH or LOW the car feels like it is braking when turning the steering wheel; the dealership can't find the problem & said do not use the 4-wheel drive feature (makes sense?). More problems w/ trans. @ 45k miles - lost REVERSE. Since then - an exhaust manifold leak & a head gasket replaced (this SUV only has 53k miles on it). Now A/C problems. AGAIN I say - BIG disappointment!
Purchased with 42k miles and now at 178k miles and still going. I perform maintenance at local mechanic when needed and never replaced the transmission in 178k miles. Brakes should be larger as others have suggested. Great SUV for families and very safe for highway and local traveling. Awesome camping vehicle for tent camping and now towing large Pop up camper. Recommend to anyone looking for late model large SUV.
This has been a solid vehicle. We've pulled a 28 foot RV, which does pull pretty tough up some modest hills. Gas mileage pulling the RV is about 7 MPG. Without the RV, it seems to range from 12 to 16 MPG depending on temp and driving habits. Lots of interior room and we love the storage in the back behind the 3rd seat. The dash lights for the hot/cold have been out since we got it. The fan speed no longer works - its always on full blast. The engine has been solid and we have had good luck with it. There are still a lot of these on the road, a true testament to their durability.
