I have a Chevy 2006 4.8. It has used 2 to 3 quarts since it was new. Fouls number 3 plug.
I purchased a 2011 Silverado 1500 WT new in Aug 2011. 6 cylinder, A/T, A/C, 4WD, cloth buckets. Runs great, very comfortable, handles great, zero mechanical problems, gets a combined 17 MPG. Would definitely buy another one.
Problems with our GM vehicles have been non-existent. We've never had a problem with any of them. Our current GM SUV has over 115,000 miles on it, and the only expenses on it in ten years have been for oil changes every 10,000-15,000 miles, one set of tires and two batteries. It hasn't even had a brake job yet. No shocks, no alignments, no belts... NOTHING.
I suppose a rare few GM vehicles may encounter problems, but with a 100,000 mile warranty that should not be an issue. If a dealer refuses to fix a problem you can go to any GM dealer. Some are much better than others. If you still cannot get the problem resolved, you can contact your local BBB or the area GM customer relations office.
In my area GM has a reputation second only to Ford in satisfying customer complaints, sometimes even after the warranty has expired. Many years ago (1971) a relative of mine purchased a 1971 Pontiac that did have an engine failure several thousand miles after the warranty expired. The GM dealer installed an entire new factory engine at no charge.
Ditto. Purchased my Silverado WT 6 cyl 8' bed the same month. Very comfortable, drives great, averages about 17 MPG around town, zero problems.
OK, great! But what does a 10 year old SUV have to do with a new Silverado. Unless you are just trying to hype GM products?
Don't know about the other guy, but I had a 2004 Silverado and a 2006 Trailblazer, both with the 6. I didn't have any issues. There are times I miss my smaller engine Silverado. Sometimes people own two of the same manufacturer and compare the two in their descriptions.
