Isuzu MU-X Q&As

Check out real-world situations relating to the Isuzu MU-X here, particularly what our experts have to say about them.

• Can AEB be turned off in a 2023 Isuzu MU-X?

  This is an increasingly common complaint among car owners who are finding that modern driver safety aids such as autonomous emergency braking and lane-keeping assistance programs are too sensitive and don’t take into account the whole picture at the time. Examples include shrubs in a driveway causing the emergency braking to activate, and lane-keeping assistance trying to maintain a car in the centre of its lane despite a looming wide-load on a truck next to it.

  I’m not sure what the solution is. But we can only hope that as cars get better and these programs more sophisticated, the errors won’t be as common. But while ever this tech relies on a computer and an algorithm, it will be doomed to (sometimes) fail. This is one of the reasons completely self-driving cars are not yet a reality on our roads; the tech is simply not foolproof yet.

  Meantime, covering your car’s cameras with tape might put a stop to the false alarms, but it might also create new problems as the computer searches in vain for the camera’s input. And your concerns about insurance hassles are well founded, too. It’s not hard to imagine the owner of a car with disabled safety features being refused cover in the event of a crash.

• Why is my 2023 Isuzu M-UX doing so many DPF burns?

  My experiences with the very latest turbo-diesel engines available suggests that DPF burn offs are being programmed to happen much more often. It’s likely to be a manufacturer response to the problems associated with DPFs that become clogged and then require manual cleaning or even costly replacement. By programming the DPF to burn off more often, the theory is that this will lead to fewer DPF blockages and other problems, making life easier for the car’s owner and reducing customer complaints.

  Perhaps another aspect of this is that the DPF burn usually takes several minutes and kilometres of driving to complete. If the vehicle is stopped before the burn is complete, it may try again for a complete regeneration (burn) as soon as possible, which could be why you’re seeing these frequent notifications on the dashboard.

• My 2015 Isuzu MU-X keeps showing a 'release park brake' fault

  Unlike some newer cars which use an electrically-operated park brake, this model Isuzu has a conventional, mechanical park brake set-up. So that’s a good start as the mechanical version is much simpler.

  The tiny switch that is operated by the park brake lever (and lights up the warning light) can often fail or short-circuit, leaving the car thinking that the park brake is still applied even though it’s not. But if you’ve gone to the trouble of changing the wiring to the park brake lever, then presumably this switch was replaced, too. Or at least checked.

  So the next thing to do is to make sure that the park brake is, indeed, releasing completely when you lower the park brake lever inside the cabin. If the park brake is poorly adjusted, you might find it’s not releasing all the way, and that’s what’s causing the problem. A quick squirt of contact cleaner on the switch would be your first move, however.

• The disable function of the blind spot monitoring system in my 2023 Isuzu MU-X is failing

  I’d be interested to know what happens after the 30 minutes when the system switches itself back on. Does it disable again if you give the connecting plug a wiggle? If so, it’s probably a poor electrical connection somewhere inside the plug assembly. If you need to turn the ignition off and back on to make the system disable itself again, then you might be dealing with some kind of computer (body computer?) problem.

  The thing is, if this is a genuine Isuzu accessory option, then it should come under the car’s new-car warranty. At which point it’s Isuzu’s problem to fix, regardless of whether the dealership you use has seen this issue before or not.
