Isuzu MU-X Problems

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

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.

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.

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.

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.

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.

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. 

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.

The MU-X is rated to tow 3000 kg, which is well above the 2100 kg you say your caravan weighs. On that basis it would seem to be well suited to your towing needs.

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.
