GMC = Government Motors Crap!
WHere do I start, Fuel economy sucks, 2 mps less than rated, been checked out no mechanical reasons, not driver error I drive conservatively.
Vehicles, people and objects disappear behind the review mirror because of the lowered roof line, I cannot clean the windshield because of the sloped design.
Your seats suck, around a 1,000 miles the foam starting softer and I now feel like I am sinking in the seat, very uncomfortable, no left ffo rest, so I am sliding around when braking.
Noisey peace of crap, stop klunks, bumps and thumps, hard downshifts.
Seats are made of cheap foam that compresses and is uncomfortable to sit on after 1k miles. I loved the first 1k miles and have hated it ever since. Fuel tank slosh when tank is 3/4 to full, you can hear it sloshing and and feel in banging from front to rear at a sudden stop. Accelerator and brake pedals are too close to together. Sole of right dress shoe get caught on right side by stupid piece of an ill conceived plastic cover. I am 6 ft & hit my head when entering in truck, roof line has been lowered too low, by inept idiots. Brake squeal at 5 and 15 mph. Trailer brake controller is low on left side of dash hard to reach and use. Stop Klunk noise. Dealers don't care.
I purchased this o9 after the deals made it to good not to get rid of 05 Right from beginning i have had a vibration from rear of truck at 70 mph and up the dealership tried swapping tires with brand new truck same tires same result GM has told the dealership what to check as they had and am now being told that i have to live with it I would like to hear from anyone that has had similar problem Truck only has 2000 miles on it something isn't right
The engineer who designed the headlamps on the GMC Sierra 2009 should be fired yesterday! You pretty much have to disassemble the front end to replace a freakin headlamp! If you don't have time to mess with it and take it to the dealer, they'll only charge you $174.86 dam dollars to put in a new head lamp which you can purchase at the auto parts store for $13. Ridiculous design!
