Isuzu D-Max 2016 Problems

Blowing a major fuse suggests that your car has suffered a short-circuit somewhere within its kilometres of wiring. But a modern vehicle like your Isuzu will also have fuses protecting the various systems it needs to operate, so there’s a chance there’s a second fuse that protects the stereo system that has also blown when the problem occurred. Your owner’s manual should be able to identify the locations of the car’s various fuses. Don’t forget to replace them with a fuse of the correct amperage or you could cause more damage if the fuse ever needs to act as a circuit-breaker again (which is exactly the fuse’s role).

The other possibility is that the stereo unit itself has an internal fuse. Check around the rear of the unit (usually where the wiring for the speakers exits the stereo) and you might be able to locate the fuse in question. This is often the case in aftermarket stereo systems.

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.

You really need to work it out with the dealer and Isuzu. I'd be asking why they don't appear interested in your plight, and press them for some sort of action. Lodging it with the Office of Fair Trading is worth doing, and hopefully that will see some positive response. Beyond that I could suggest a lawyer's letter to the company demanding they take action.

It's an unproven brand, which is why they are cheap. It was the same with Great Wall and their resale values reflect the way owners and potential owners feel about them. I wouldn't do it.
