I was at the dealer for other work and was chatting with the mechanic about anything they see coming in on the 2013 Edge with 3.5L V6.

He said that one thing they see a LOT of is dirty or failed Throttle Body.  That they recommend having it cleaned every 15-20K miles.  For $65 no less.

So, I googled around for an hour or so and came up with NOTHING on this issue.  Is this another "dealer service scam" or is this a REAL problem?  He described it as causing the car to stall and, if bad enough, to not run at all.  He also said that there was a "national shortage" of replacement throttle bodies due to the problem. 

 

You'd think that would show up somewhere if it were happening with such regularity.

 

Anyone familiar with this issue or have this problem??

my dad is a parts and service director for a Ford dealer in VA, and i have been having problems with my 08 3.5L. i asked him about it and his first thought was the throttle body as he sees alot of those come through. i would say, just by what he was telling me, that there are problems with them. not real sure about year models though.

I can understand mechanical/electrical throttle body issues...but dirty TB's? Why would they be getting dirty TB's on 2013's? Strange info if you ask me!

Especially since there is an air filter ahead of the the TB, and there is no PCV vent pre-TB!  Is the TB clogging from the intake manifold side?  Blowback maybe?

It's oil from the pcv that comes into the intake tube from the left side (when looking from the front.)

Hmm.  Maybe a catch can is in order if the TB is getting dirty from that.  Space is already plenty tight in that compartment tho.

Some good discussion so far... but not the "confirmation" I'm looking for.

 

I did more googling around and found a couple of cases where people had to have their Throttle Body replaced... one at 15k and another at 33k... but no mention of any regular service required or further issues after replacement.  Replacement with that low a miles sounds like defective part from the start.

 

I searched all the "official" Ford sources.  The manual has no mention of it.  In fact, one thing that makes me suspicious of "dealer service scam" is that the Ford info calls for radiator and tranny flush plus spark plugs at 100k and this dealer tried to tell me every 30k for flushes and 50k for plugs.  Which I knew was bogus or Ford shouldn't be building engines at all.  I've run other V6 engines 100k before doing any of that and my daughter has one of my old cars that now has 180k on it and has had ONLY plugs and an O2 sensor at around 110k and no other issues in all those miles.

 

So, looking for that person who can confirm that the TB will fail early and often if not serviced (cleaned) every 15-20k miles.  Or that there really is a "national shortage" of TB because of failures... which sounds like a case for a recall to me.  I still think the dealer is looking for a fast $65.

Quote directly for the Ford Service Manual:

 

The TB :

  • controls air supply to the intake manifold by electronically positioning the throttle plate.
  • is not adjustable.
  • cannot be cleaned. 

Not only is cleaning not required, it should never be done and would technically void the warranty on the throttle body.

OK!  Waldo, that's the type of info I was looking for!!

I assume you have the Service Manual?  Where can I get one?  And, most importantly, I would like to have the part on the TB that I can copy/paste into an e-mail to my "great" dealership service manager.

I had a feeling what they were telling me was WRONG!

 

THANKS!!!

OK... I had a chat with the Service Manager at a local Ford dealer.  He swears... and he sounded sincere... that there is a FLAW in the TB design.  That Ford has fixed it.  BUT... there are nowhere near enough of them available.  "A nationwide back order status." according to him.  That, when they catch up, there will likely be a Service Bulletin for this issue.  He still thinks that cleaning it at 15-20k miles will avoid a failure until they can replace them.

So, I'm keeping an eye out for this.  Still surprised there's no real info anywhere on the interweb.

Definitely going to DEMAND a new one before my warranty expires.  This, to me, seems like it justifies a RECALL not just a TSB.

It is true that there are a lot of throttle body failures, but cleaning them is not going to make any difference.

Noticed a mpg drop over last week after filling up Costco gas.  Took it in for service at dealer.  Dealer suggested MAF cleaning with BG service/Air Filter replacement, stating that the throttle bodies get dirty.  Guess it's time to look inside the Edge's throat myself.  Yippee!

Demand that they replace your TB with the "new improved" version.  I found out there has been a nation-wide backorder since spring... because they will ALL fail eventually.  Hopefully the BO is clearing out.  But that tells you that it is a problem for ALL the engines. 

I will absolutely demand mine be replaced under warranty... just waiting a bit to make sure they can actually get one when I do.  I'm thinking spring cause I have time left on the warranty.

This is a REALLY SAD thing for Ford to pull right when they are kicking butt in the marketplace.  Sigh...

I hear ya, Maavalous1!  Just might do that.  BTW, the dealership found nothing wrong with the Edge at all.  It was just a "suggestion" to get the service.  To their credit, assuming someone actually looked at the vehicle, they did not charge me anything for the "diagnostics" :)

Dimples, what symptoms were you having to merit the replacement?
