Isuzu MU-X and D-Max: Cracked inner guard in engine bay

Have there been any reports of cracks appearing in the inner guard in the engine bay just forward of the compliance plate of the Isuzu MU-X?

I have seen some reports about the D-Max that seems to have the same complaint. I have an OEM bull bar and have upgraded the suspension to a 2-inch Old Man Emu lift. Our 2015 MU-X does the occasional off-roading and has done one big trip across the desert, but is mainly used on road as a passenger vehicle.
