Please also check out the statistics and reliability analysis of the 2007 Chevrolet Silverado 1500 based on all problems reported for the 2007 Silverado 1500.
The truck is in excellent condition and has been well-maintained. At 127,000 the engine started making a noise diagnosed as lifter noise. Within a hundred miles or so, while driving on a highway, it started to make a very loud noise, and again diagnosed as lifters on at least 2 cylinders needing replaced. Upon the advice of a 25+ year gm mechanic I will be replacing the motor as this is most cost effective as well as buying a program chip to bypass the "active fuel management" which has caused the problem. This was also recommended as gm has not altered anything engineering wise to prevent this from happening on a brand new motor that would be purchased from them.
