2009 GMC Sierra 1500 SLT 4dr Crew Cab 5.8 ft. SB (5.3L 8cyl 6A)
I purchased by GMC in November, from the very beginning I noticed an uncomfortable ride. I called the dealership, they advice me to bring it in. I complained about the hard downshift and they took a test drive and said that they couldn't replicate the problem. But they did find that the tires were out of balance. It was dissappointing to find out that a new vehicle was not inspected properly from the factory for this. But the hard downshift still remains.
Nice interior, driver seat needs to be more comfortable with a center fold down console, should have purchase one without fold down, instead with a full center console, front seats would have been whole and more filling.
Transmission, neet to improve the hard downshifts, makes ride uncomfortable and not smooth.
