2017 Focus RS Rev. Hang/Climb problem.

If pulling up on the pedal fixes the issue, then it sounds like you just need to have them replace the gas pedal. The sensor is part of it.... and I'm not sure if it can be replaced on its own. Or maybe the return spring on the pedal (or some part related to that) is wearing out.

I don't recall seeing anyone else here that had that issue before.

Thank you for the response. I have said that to them and they told me that can’t be the problem. They don’t know what is wrong and they are calling it normal and want to give the car back to me with fixing the issue. The cars warranty end in July this year.

They said it themselves that the car is fly-by-wire, so how could the pedal assembly not be related? It sounds like the dealer is just being a dealer. Good luck getting them to look more into it! They should at least be looking at the TPS value to see if the throttle is being commanded open during those rev hangs.

Some rev hang is normal during the warm-up process. During normal driving there shouldn't be any hang, other than the couple seconds of rev matching that the car provides.

Luckily the part is very easy to replace, but I'm not sure about its cost. Not that you should have to pay for it, but just in case....

I appreciate that. I have not said that to them. I will go see them and tell them what you said. I really appreciate the help. Maybe they will look more into those two things.

Take it elsewhere, clearly that dealer is shi7.

That will be the next step. Thank you

Excellent advice from morbid and Jamo!

Obviously; I don't know who you've been talking to/dealing with at your dealer---------but, have you tried (politely) taking it up "their" chain of command? If not it might be worth a try. Hope you get it fixed right on their dime soonest!

They sent it to ford. It’s ford telling them that the car is running normal. I believe that they Don’t trouble shoot cars anymore. They plug in their diagnostic device and wait for the answer. If the car is not kicking any codes they don’t seem to ever know what to do.

You might as well get the car back and replace the gas peddle assembly yourself. Depending on which one you get it’s less than $100 from RockAuto. Also, if you’re getting rev hang like that after the car is warm it’s 100% the pedal assembly. I had that problem and know I’m not the only one and that’s the solution pretty much always. I even tried taking logs and video of it for the dealer and they just didn’t either understand or get how to fix the problem, despite me giving them the answer. For some reason it’s either a high failure part on RS’s or we complain about it more because I’ve seen them on this form and on The RS Facebook group.

TLDR, just replace it yourself. It’s 2 bolts and 15 minutes.

If you're replacing the pedal assembly and wanting a gas pedal spacer, you could add that during the install of the new pedal, and make the process even better.

Thank you for the response. If they don’t fix it I will do that. I will also let them know that you had the same problem and was able to fix it with a peddle assembly.

If you need a throttle body let me know

Had the same issue. For me, it was the pedal. Took about 10 minutes to replace it myself (time-value prop for me it wasn't worth waiting on the stealership to realize it was the issue). If you search for that part #, it came on several Ford models. I got one from eBay for $43 shipped.

Thank you for the response. I told the dealer that it was the peddle. They replaced it. They said it fixed the problem. I will be picking up the car today. I appreciate all the information I received here. It was a huge help. Also my warranty runs out in July so I will look here for advice on any other problems. Thank you all agin.

Let us know if it indeed fixed your issue.

I will.

I drove the RS most of the day yesterday and this morning. The gas pedal assembly replacement fix the issue. The dealer listened to me when I told them I join this forum and that the problem was the pedal assembly.

Most dealers/mechanics/tuners hate it when you mention you got the information from a forum, since there is sometimes misinformation on forums, and they just want to do their job. I'm glad they listened to you about this though!
