Isuzu Problems

While all second-generation Isuzu D-Max pick-ups ride on a 3095mm wheelbase the other dimensions differ depending on the specification ordered. The single cab is 5215mm long while the dual cab is 5295mm in length. Widths range from 1775mm to 1860mm, and height ranges from 1690mm to 1785mm depending if you choose a 4x2, 4x4, single cab, space cab or dual cab.

The idle is too slow to maintain running, so check and clean the airflow sensor in the intake, and replace the air filter.

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’s clearly frustrating you, but I don’t believe you’ve copped a lemon on the basis of what’s happened. Isuzu fixed the diff, end of story, they also replaced the first pump under warranty, again end of story. The issue is why have two pumps failed, and why didn’t Isuzu cover the second pump. These are questions I would be putting to Isuzu. I’m guessing that the second pump wasn’t covered because the warranty had expired after three years.

Mining company utes operate in the harshest environments there are, so I wouldn't take a lot of notice of hearsay reports of problems. The chassis might indeed crack under the stress of the mining site, but that's a far different environment than anything you will encounter in your travels.

Don’t mess about fit another EGR valve.

There’s clearly something wrong with it. Take it to a dealer and have it diagnosed.

It’s true that diesels are at their best on longer trips when they are fully warmed up and not accelerating and decelerating all the time. You can have problems with the DPF clogging up and not regenerating if the car isn’t getting up to speed for any length of time. You could take it for a run on a highway or freeway once a month or so to get fully up to working temperature, so the DPF burn-off car hopefully happen. If the burn-off doesn’t happen automatically you face the prospect of having to have the dealer do it manually, and that would involve a cost.

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 ADR requires carmakers to have a side indicator so there is always a visible turn signal light, so you should be able to see that even if you can’t see the front light.
