The wife's 4.8 has the self leveling suspension inactive message coming off and on. Somedays its on.......and some days its off. I replaced the coolant tank back when we bought it (apprx a year ago) because the tank was leaking. Then, took it in to get a new battery, and they said I needed a new coolant tank. wtf?

They said this one was leaking, so I took them the receipt of when I bought the first one, and they said I installed it correctly, but it was leaking again so they covered it. Anyways, now they are saying that since it was leaking down onto the computer, its throwing it off making it think that the self leveling suspension is messed up, when essentially it was bad design/placement of the coolant tank, and thats why it is coming on. Just wondering if there is anything I can do about this before I drop money on a new computer? The SLSI light is off for right now and everything rides good, but Im sure its just a matter of time before it comes back on and rides like a wagon with no springs.
