My Honda dealer found DTC 151-11 and wants to update the VSA modulator-control unit software based on TSB 14-006. I've seen a few posts on this in the thread. However, because the code posted only now, they won't cover the update under warranty and want $140 for labor to do this. Is this reasonable? It didn't develop because of mechanical wear; it was a known software bug in 2014 prior to when I bought the car certified pre-owned. It seems absurd that they won't cover this.
