Metallic odor in the Santa Fe salon may occur if the full-drive lock is turned on. He's talking about a scuffle. But more often, the problem lies elsewhere. With low quality fuel and heavy load on the engine (e.g. off-road), the unburned residues of high sulfur fuels are burned into the catalyst and are the source of an unpleasant odour. To correct this problem, we need to refueling quality fuel and "burn" the catalyst on forced regimes. Another cause of smell may be the specific exhaust of diesel engines with the Common Rail system.
