Isuzu MU-X Problems

The Jeeps are perfectly capable of doing the trip you are planning, and if anything did go wrong while you were away there are dealers all around the country who cold fix it for you. At 2000 kg your caravan is not particularly heavy and shouldn’t stress the Jeep at all. The Prado is the other obvious choice, and it too will do the job with ease. Others to look at are the Kia Sorento and Isuzu MU-X.

It could be some form of wind noise, either from the door seal, the rear view mirror, windscreen trim, or anything else that might be in the wind stream. To check the door seal, try running a strip of tape around it to block off the door gap and see what that does. It’s going to be a process of elimination.

I wouldn’t go on a trip without fixing the issue. I'm surprised to hear that there is no stock in Australia, but I would reach out to Isuzu Ute Australia head office if you've only tried dealers so far.

UPDATE 12/2/19: Greg advises that this part was replaced under warranty shortly after this response was published. 

The MU-X is solidly built and reliable, and I can’t see any reason why you should be unsure of it. If you want a seven–seat SUV it’s worth considering.

It could a sensor in the ABS/TCS system; it could perhaps be the computer controlling the electronics. You need to have a diagnostic check done on the car to properly identify the cause of the problem.

It’s good insurance, particularly if you are going to be towing, as you plan to do.

What do you know about its history before you bought it? It could have occurred before you bought it, and just shown up now. It’s not something we hear about.

We haven’t had anything reported to us about cracking of the inner guard, but like you have seen reports of cracking on the D-Max. That suggests it could also affect the MUX.

Because of the modifications you have made, and the off-roading you have done, I doubt you would have any success if you were to make a claim against Isuzu for repairs.

It's not something that we have come across before, and it doesn't seem right, but it needs further investigation to find out if it is a normal function of the car or a fault. I suspect the latter, but couldn't say one way or the other without witnessing it do it. Take it up with your dealer again, and if he says it is normal with the MU-X ask him to demonstrate it on another car. If he can't reproduce it on another one press him and Isuzu to investigate why it's happening on your car. If he can show you that it does happen on others you have to believe that it is an in-built fault with the MU-X.

They all have child seat anchorages in the second row, but you're right that the Everest has anchorages in the second and third rows. The Everest would be the one to go for; it's got the most up-to-date cabin and would be best suited to your needs.
