2026 Mitsubishi ASX Pricing and Specs

There are several things that could be causing a loss of power on really hot days, but a prime suspect would be an engine that is getting too hot. When that happens, the car will often go into limp-home mode which is usually signalled by a loss of power and a check-engine light illuminating (the precise symptoms you’re seeing).

The air conditioner consumes quite a bit of engine power when its working, and this extra load might be the tipping point for the car starting to overheat. When you switch it off, the engine can relax a little and the temperature falls. So the advice would be to have the car’s cooling system checked. It could be low on coolant or have a faulty pump, hose or thermostat. While you’re at it, have the car electronically scanned to see if any fault codes have been recorded, as this will also help your mechanic diagnose the issue.

It’s amazing where rainwater will get to under the influence of a pressure difference between the inside and outside of the car, not to mention a 100km/h gale trying to blow everything inside the car. As such, you only need a tiny tear or crease in a door rubber for water to enter the car. And if it enters somewhere near the driver’s seat, that’s where it will stay when it hits the carpet.

Check the rubber seal in the door opening for any signs of damage or a small chunk missing. Even a piece of leaf debris stuck to the rubber can allow a gap big enough for water to enter. Make sure, too, that the door itself is properly aligned on its hinges and is making contact with the whole of the door rubber when it’s shut.

The ASX was launched in Australia in 2010 and from the very start was offered with a CVT transmission, as well as a conventional manual transmission, depending on what specification you chose. The ASX’s CVT differs from some by having six fixed steps which makes the car feel and sound a little less alien to drive, but also potentially sacrifices a small degree of efficiency. That’s because the CVT is most efficient when allowed to use an infinite range of just-so ratios, rather than the six fixed ones Mitsubishi specified.
