Have a 2018 4x4 Silverado with eassist truck that I love but... when I apply light breaking pressure the whole truck can start to shake(normally backing, 4x4 not engaged, under 3 mph, and not always). Brought it in for service/inspection and was told this was normal??
Other- get about 19-23 mpg, much better than my 2012 silverados 14mpg.
