If you ar planning on buying a new Silverado, DON'T. One of the worst vehicles I have purchased. I bought mine 2015 brand new and with in 2500 miles the transmission went out. I now have a problem with the 4 wheel drive being stuck in 4 high. Not the first time this has happened. From everything I have read all the problems with the 4 wheel drive has been going on since at least 2004. If Chevrolet can't figure out how to produce a quality product the maybe they need to find new engineers. Again do not waist your hard earned money on a half ***'d design like the Silverado. Chevy just lost a long time customer. Probably going with dodge next since Ford went to aluminum crap. What happened to vehicles that actually lasted?

 

Of course they know how. 4WDs have been around for ages. They're just trying to save money (at your expense).
