GMC Sierra 1500 Reliability and Durability: Cons
YearBody/PowertrainComment
2006 4dr Extended Cab 6.5ft bed 295-horsepower 5.3L V8
4-speed automatic 4WD w/low range
Slightly better than Dodge, but at the bottom of the reliability pile. This truck is on its third set of front wheel bearings and a new alternator at just 130,000 miles.
