Hi guys! I’ve been driving a new Santa Fe Diesel, automatic for 3 months. Had to take it a little harder yesterday on wet meadow and Maisacker, because it finally got more muddy than I had initially suspected: On a slight incline, with slightly spinning wheels, it went slower and slower to a standstill. It was a slight incline, therefore set back, was difficult, but went, then again, tried to take a little more swing, did not go back. before, the track was probably a little tighter, the wheels picked up a little better, then suddenly indicator light of the 4wd-lock turned on and – standstill! Luckily one day before I had read a test in the car-picture-all-wheel, that the all-wheel system of the Santa Fe passed itself when overheating and switched everything to front-wheel drive. Otherwise I would have thought that something had broken. Only with front-wheel drive of course one has the feeling that there is no traction at all So I waited 2 minutes, again set to 4-lock and I slowly pulled myself out of the mud! Now my question to the forum: Does this happen more often, for example when driving free from high snow? Does someone know why the central differential overheats, although one actually suspects that it would have to be firmly connected when you have operated the 4lock switch and should actually not cause frictional heat? I am grateful for all the answers except comments like: On such fields one does not drive where one sinks almost 20 cm! Tires were of course not MT, but new winter tires Bridgestone 4×4.
