I recently bought a 2012 sport DC. Ive had it for about a month now. Its not my daily driver so it only has about 300 miles on it. yesterday, after not driving it for about 5 days, i took it to run some errands. When i turned it on, the TPMS light was on. Wierd i thought. I checked the tire pressure in all 5 tires and they were all around 32-33 psi. Spot on. The ride after this was and continues to be awful. Its like i am constantly off roading. I can feel every crack and bump in the street. its a very rough ride. It was not like this for the first few weeks. It was firm but smooth. Now its very harsh. Im at a loss. Brand new truck with stock suspension. I had a TRD off road before this, and the ride in it was 10 times smoother. Any thoughts would be appreciated. Im pretty pissed right now.
