 Reading other reviews and it appears that the sluggish acceleration, constant gear hunting and rear end noise that I have are symptomatic for this vehicle. I've had the truck back at the dealership 4 times already for a reflash of the transmission firmware and the noisy rear end. The transmission still hunts all over the place when I'm on the highway and the rear end is still very noisy. I haven't experienced the leaking that others have complained about yet but I suspect it won't be long before I do. My brother bought a Colorado shortly after I bought this truck and after driving his I wish I had as well. I'd like to dump this truck now but I know I'll take a bath as I already have close to 10K miles on it. This is my second bad experience with a Toyota product and it will be my last.
