• Isuzu MU-X and D-Max: Cracked inner guard in engine bay

  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.

• 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 2018: How much can my car tow?

  It’s not a good idea to be towing in fifth gear into a head wind or uphill, or in other adverse conditions. If you do the gearbox will shift back to fourth, or lower if need be. I wouldn’t be too concerned about towing a larger van, providing of course it doesn’t overload the MU-X. You could upgrade the turbo with a chip or other device, but in my view you’re risking trouble by doing it.
