For the slip light, are you accelerating hard and loosing traction? Do you feel the truck loosing power? If thats the case than its doing what its meant for, which is to control the power output of the truck so you dont lose control. Its annoying as heck when your trying to screw off. I turn my vdc switch to off.:redblob"So I bought my titan a few weeks ago and I love it. Only a few problems though. When I turn the heat on to upper and lower it makes a clicking sound for like 10 seconds then shuts off. The sound is coming from the inside the dash. Also when I am accelerating from a stop sometimes the slip comes on and it sounds like its grinding something. Any help at all to a young kid with a big truck:redblob"
