• Cracking on 2019 Isuzu MU-X air conditioning dial LCD display

  It doesn't matter whether it's a common fault with this make and model, because the reality is that the vehicle is still under the factory warranty, so it's Isuzu's problem, not yours.

  Provided, that is, that the fault occurred on its own and not as the result of an impact that would be deemed accidental damage.

  Generally speaking, these LED information screens and other touch screens are pretty reliable and robust, but problems have been known to occur including loss of touch control and the sort of crazing you're noted. Isuzu is not alone either, and many brands have similar issues. The crazing can also be the result of temperature extremes (hot and cold) and will sometimes go away when the ambient temperature returns to a more moderate level.

  The type of problem can often be fixed by replacing the actual screen (or in this case, rotary dial) rather than the entire control unit. But it's a specialist job and involves dismantling at least some of the dashboard to achieve.

• Why is the fuel consumption high on my 2019 Isuzu MU-X?

  A lot of people buying this type of vehicle are horrified the first time they work out their real-world fuel consumption and compare it with the official sticker on the windscreen. Frankly, very very few cars can get anywhere near that official figure. It’s the result of a standard test that bears little relationship with real driving and it’s really only for comparisons with other vehicles, not a realistic idea of what to expect.

  Even so, 14 litres per 100km at highway speeds does seem high. Being a 2019 model, it won’t be that the engine is still brand-new and tight, so we can rule that out. But, there are many other factors that affect fuel consumption more than you might imagine. Does the car have a roof rack fitted, for instance? If it does, you can easily use an extra litre per 100km at freeway speeds thanks to the extra drag. And that’s if there’s nothing on the rack (it will be worse loaded).

  Is the car carrying a lot of accessories such as a bull-bar, rear step, extra fuel tanks and maybe even a winch? All these add weight and weight kills fuel economy. What tyres are you running? Big mud tyres with an aggressive tread can drastically ruin fuel economy, so can taller tyres than standard which mess up the gearing and force you to use more accelerator pedal than a car on standard tyres. Also, the road from Melbourne to Wagga is mostly freeway with a 110km/h limit. Experience has shown that most cars will give their best fuel economy around the 80 to 90km/h mark, and every kilometre over that sees fuel economy go downhill. There could be a very big difference in your car between 100km/h and 110km/h. Even a stiff headwind in a big, bluff-fronted car like a MU-X can make a difference over the distance you’ve quoted.

  If none of those factors are at work, then you really should have the car scanned to see if there’s any problem with the mechanical or fuel systems. Even a dirty air filter can cause a big hike in fuel use, so a once over at the workshop might reveal the answer.

• Why is the fuel consumption of my 2019 Isuzu MU-X getting worse?

  My initial thought is that 11 or 12 litres per 100km for an overall average is about what I would have expected. These are not small cars, they’re not light and they have fairly ordinary aerodynamics.

  What you need to keep in mind is that the official fuel consumption figure is a number achieved on a very specific test cycle that in no way approximates a real-world experience. Car makers go to great lengths to nail a good number on these tests (for marketing purposes) often at the expense of real-world fuel economy. Yes, it does seem crazy, doesn’t it?

  You also mentioned you use your car mostly for high-speed driving. What’s your definition of high speed? Thanks to the aerodynamics of vehicles like the MU-X an extra 10km/h at freeway speeds can have a huge effect on economy. Even removing a roof-rack when you’re not using it can save a litre per 100km.
