Isuzu MU-X 2017 Q&As

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

• Vibration and engine labouring in my 2023 Isuzu MU-X

  What you’re experiencing is the transmission calibration that many modern vehicles use to increase fuel economy. By always trying to be in a higher gear, the vehicle will record a better fuel economy number on the official test that compares it with its competitors.

  The downside is that the constant upshifting means the vehicle will sometimes find itself in a gear that’s slightly too tall, and that’s when you’ll start to get the symptoms of feeling like the engine is labouring or lugging.

  As you’ve noted, when the car shifts down a gear, the sensation goes away. The solution is to manually pull the car back a gear when this happens. If t really bothers you, you could ask Isuzu if there’s a software update that makes the transmission a little less eager to be in top gear.

• Why did the wheel on my 2021 Isuzu MU-X fall off?

  Unless the wheel nuts have sheared off or the bearing or axle failed catastrophically, the most usual way for a wheel to fall off a moving car is if the wheel nuts were not torqued properly by who ever removed the wheels most recently. Has the car ever had a new set of tyres? Or was the wheel that jumped ship changed at any stage because the tyre was flat?

  Perhaps the best advice is to approach your state motoring club. These clubs often operate a technical inspection service where the cause of faults can be determined and a written report supplied. This is then considered an independent source of evidence and may be helpful if the matter is taken to a dispute hearing.

• Why has the fuel consumption in my 2018 Isuzu MU-X increased?

  The first question to ask is have you changed the way you drive the vehicle. Driving style has a huge bearing on fuel economy, and if you’ve started to drive the vehicle harder or even on roads that are more winding and hilly than before, a jump in fuel consumption is common. On that level, is it just you driving the vehicle or is somebody else using it lately who might have a heavier foot than you?

  Have you added a roof rack or more weight in the form of a winch. Even a new set of more aggressive or larger diameter tyres can do terrible things to fuel economy. But if the answer to all that is no, then you need to have the car scanned to see if any fault codes are thrown up by the computer. And when was the engine last tuned? Is the air cleaner free of dust and are the fuel injectors working as efficiently as they should be?

• Isuzu MU-X transmission is dropping out of gear

  The first thing to check is the fluid level in the transmission. Consult the owner’s manual for the correct method of doing this (sometimes the engine needs to be running and the transmission at operating temperature, in other vehicles everything needs to be cold, so this is important).

  Low transmission fluid can cause all sorts of problems with gear selection, flaring between gears and actually making the vehicle drive, so that’s why this is the first step. If the level (and the condition) of the fluid is fine, then you need to start looking deeper, and a transmissions specialist is probably your best bet there.

  The transmission is a sealed system, so any drop in the fluid level suggests a leak somewhere that needs to be fixed or the problem will return.

  Beyond that, running a transmission that isn’t behaving properly can cause damage to the unit itself, so continuing to drive the vehicle in this state is not a good idea.
