After 70,000 have only had one problem
By ~CRASH~ on
2006 GMC Sierra 1500 Work Truck 2dr Regular Cab 4WD 8 ft. LB (4.8L 8cyl 4A)
I love my truck, its mainly a work truck but I put more miles on it than any of the other trucks. Yeah after about 15,000 miles dash started rattling but till after 70,000 miles it's been loyal and I beat the hell out of this truck i.e. racing, fish tailing around corners, bad terrain. And so far the tranny dumped out on acceleration at 50 mph. Rebuild was 850. So no bad review here.
5.3 L v8 flex fuel motor.
disk breaks all the way around, center seat needs to fold down, needs a better transmission cooler.
