In this note we give three counter-examples which show that the Maximum Principle generally fails for classical solutions of a system and a single equation related to the \infty-Laplacian. The first is the tangential part of the \infty-Laplace system and the second is the scalar \infty-Laplace equation perturbed by a linear gradient term. The interpretations of the Maximum Principle for the system are that of the Convex Hull Property and also of the Maximum Principle of the modulus of the solution.
