Broke down in March 2003 with this 2000 GMC 1500 6 cyl pickup at 73000 km and had to be towed. The distributor cap acquires moisture buildup and kills the spark. I am the second owner so this may have happened before. The towtruck operator and other owners in this area of Eastern Canada said this is a common problem with the newer Chev and GMC pickups in our Canadian wet but cold and damp weather. My previous 1988 Chev went for 15 yrs without this problem. What did they change?
This is a great truck, fun to drive, rides good, can haul a load, and its quick. Gas Mileage isnt bad for a full size truck with a V8. It has som weaknesses, like too much plastic inside and out. Weak bumpers (front especalliy) , and the metal on the tailgate and bed sides is too thin. but this is a great truck otherwise, and the best new truck you can get, but they sure dont build them like they use to
Overall, I love the truck. It fires up every morning. I have had it for almost four years. I drive 30,000 miles a year with my job and it holds up great. The biggest repair I had to make was to have the intake manifold gaskets replaced a few years ago. The Gen III LS-based engines are notorious for that. I get about 15-17MPG no matter what kind of driving I do. Piddly things are starting to fail like lights on the radio & HVAC, lumbar support, and the console lid, but mechanically, it's as Professional Grade as ever! Someday I'll trade it in on a new Sierra/Silverado, but right now it does what I need it to do.
Great truck with only a few minor problems. A few rattles (never off- road)and the tranny shifts odd in the cold weather. Tends to wheel-hop while braking over uneven surfaces even with anti-lock brakes. Awesome sound system and wonderful ride! I would buy another one.
