Why does my 2018 Ford Ranger Wildtrak stutter when accelerating?

Asked by Glenn

I have a 2018 Ford Ranger Wildtrak. Over the last two weeks whilst overtaking - accelerating up a hill at approximately 80-100km/h - the vehicle doesn’t gain full power and feels like it is stuttering. It has gone to Ford once and they said they couldn’t find anything. Any suggestions or help?

This gets a bit political, because Rangers delivered after May 1, 2018 carried a five-year factory warranty, but cars sold before that date had just three years of factory cover. Which means that if your car was sold new before May 1 2018, it will now be out of warranty and, if it was sold later than that, the problem is still Ford’s as the warranty should still apply. Even so, it would seem fair that Ford should offer some pro-rata cover for a car that was built in early 2018 and missed out on the five-year warranty by a quirk of the calendar. But don’t count on it.

As for the actual problem, have you noticed any warning lights on the dashboard? If so, that could be a clue to what’s going on. But unfortunately, there are many, many things that could be making a modern turbo-diesel engine run poorly. Rough running or stuttering, for instance, could be caused by anything from a blocked fuel filter, worn fuel pump, faulty fuel-injectors or a DPF system that is blocked. Or any of literally hundreds of other things.

The best advice is to have the car electronically scanned to see if the on-board computer throws up a fault code. From there, you can home in on the actual problem without a hit-and-miss approach. That said, I would have expected a Ford dealer to have tried this already, so maybe it’s time to try another dealer. And don’t forget to press them on the warranty situation.
