I have just replaced the second intercooler hose in my 2018 Mitsubishi Pajero Sport in succession. Heads up: If you're replacing this yourself you need to twist the bottom section before tightening, if not it will sit too close to the fan pulley and tear.
Why hasn't Mitsubishi addressed this issue?
This problem has occurred before and happens when the pulley rubs through the hose, which finds itself in the wrong position under full turbo-boost. From what I can gather, the problem is due to a running change in supplier of this hose. And even though the hose was a slightly different shape, the manufacturer used the original alignment marks from the previous hose. So, when the mechanic fits the new hose, it places it in the path of the fan pulley when the engine comes on boost.
Ideally, the hose needs to be fitted so that there's at least 25 or 30mm of clearance between itself and the pulley. Your twist-at-the-bottom method should work, because you're effectively altering the incorrect alignment marks to where they should be.
