You might find that at high throttle inputs, the car’s computer is switching the fan on in anticipation of higher temperatures. Or, perhaps it’s the air-conditioning fan that is switching itself on to keep things cool, because you’re using lots of throttle at that moment. It could simply be that the fan itself is noisier when you spin it harder (in line with engine revs) and that’s what you’re hearing in the cabin.

If in doubt, make a note of this with the service department when the car gets its first service. Perhaps it’s not a fan at all, and the noise is the result of a poorly adjusted drive belt or a leak somewhere in the air-intake or turbocharger plumbing. Any small leak in the trunking that conveys the pressurised air from the turbocharger to the engine can contribute a range of hissing noises.

Either way, it should be a simple fix at best, and a warranty claim at worst.

If you check out a lot of used-car sites right now, you’ll see that a 2016 Navara ST-X can cost anywhere from $10,000 to $55,000. Why the huge price-range? Because there are so many variables with this type of vehicle. Frankly, I’d need a lot more information to make any sort of educated guess on the value of a car I haven’t even seen, so I’m not going to offer one.

Because this type of vehicle is often used off-road, its condition is crucial. If it’s been bashed up, you can take thousands off the price. Has it been a hard working tradie truck, towing a huge trailer every day? How’s the service record? What distance has it covered? What accessories are fitted? What’s its overall condition? Has it been heavily modified (A lot of Navara four-wheel-drives have)? Is it a dual-cab, single-cab? Is it fitted with a tub, a canopy or a drop-side tray?

Without all this information, it’s simply impossible to hazard a guess at the vehicle’s value.

This is a typical car company response to the problem of pedal error which has raised its head many times since about the 1980s when car maker started getting sued by drivers who had pressed the wrong pedal, but claimed the car had accelerated of its own accord.

The solution was to make sure that if the driver accidentally pressed the throttle, if they also pressed the brake in panic, the car would stop accelerating. By pressing the brake and throttle together in your car, you’re reproducing that exact situation. So, really, there’s nothing wrong with your car, and it’s only doing what it’s programmed to do.

A lot of drivers don’t like this feature, however, as it means the slightest hint that both the brake and throttle are applied at once is enough for the car to cut its power and not move, as you’ve discovered. Many have found that when trying to enter fast moving traffic or make a quick lane change, and operating both brake and throttle at the same time for a quick getaway, this function is actually dangerous.

Unfortunately, there’s not a lot you can do about it other than learn to not even brush the brake pedal when you want to make a quick start.
