Engine problems with the 2017 Ford S Max: loss of power and hissing noises

Loss of engine power

Shaking while idling

Unsteady engine

Check engine light on

Jerking on acceleration

Loud hissing on acceleration

Hey guys! I have a problem with my 2017 Ford S Max with 127,960 km mileage and a gasoline engine. The check engine light has been on for some time, the engine has lost power, runs rough, twitches when accelerating, makes loud hissing noises and shudders at idle. I suspect it could be due to leaks in the intake system? Have any of you had similar experiences and can report on your visit to the workshop? I would really appreciate some tips, as I had a rather bad experience last time. Thanks a lot!

Hey, sure, I had a similar problem with my 2014 Ford Galaxy. The symptoms you describe sound really familiar. What finally helped me was that the intake hose was leaking. At my garage, they checked the system and found that the intake hose was quite pulverized and therefore leaking. They replaced the hose and after that the car ran clean and stable again. It took a while to find the problem, but it definitely wasn't a bad defect that could ruin the whole car. Hope this helps!

Hey, that sounds exactly like my problem! Thanks for the tip about the intake hose. Can you remember what you paid for the repair? And did anything else crop up afterwards or did everything go smoothly?

Hey, sure, I remember it well - the repair cost me €100. Expensive fun, but since then the intake hose has been tight again and the leak in the intake system is a thing of the past. Since the visit to the mechanic, the problem has not recurred and my car purrs like a kitten. Everything has been running perfectly and smoothly ever since. Hope this helps you!

Great, that reassures me a little. Of course, €100 isn't exactly a bargain, but if it helps, it's worth it. Your input is a great help! I'll be at the workshop tomorrow and will tell them directly to take a closer look at the intake hose. I'll then report back on how it went. Thanks again!

Intercooler pipe was broken ... part number for Ford Edge -> 2462863 cost 605€ as pipe is only offered in conjunction with the hoses ... quickly looked in the bay and bought a new one for 15€ ... installed fault rectified Greetings ✌🏻

It's great to hear that you've found a solution, Schnitzel. However, AnniWinter, I would still recommend having your car checked by a professional mechanic. The symptoms you've described could also be due to other issues such as a failing spark plug or fuel injector. It's always best to get a comprehensive diagnosis to ensure all potential problems are addressed. Please keep us updated on your progress and don't hesitate to ask if you have any further questions.
