I bought my 2018 F150 PS Diesel used at 18k miles. Very shortly after that it started over heating. The issue was traced back to a recall repair that was done poorly and led to the replacement of both turbos and my dealership having my truck for about 8 weeks. This was before I took possession. Since then all was well, regular maintenance and was well cared for. Check engine light let to a code requiring a new DPF, and current one is “cracked”. This will cost over $3K and is not considered under power train. Can anyone guide me to any possible connection to the original issue and this one. I can’t afford that and common sense says it’s related OR it’s a manufacturer defect. Any guidance is appreciated. - Stacey

@SSBL - let me be the first to welcome you to the forums, although I would have preferred it be on a better note...

Any idea what you Vehicle manufacture date is? You "might" luck out with your 3yr/36K Bumper-to-Bumper Warranty.

You are well below the 36K part of the 3yr/36K Bumper-to-Bumper Warranty, but probably very close to the 3 years:
  • 2018 F150 PSDs (Power Stroke Diesels) were very late 2018 Model Year
  • Earliest delivery we saw here are the forums was June 2018
  • My 2018 Platinum was factory-ordered at end of Jan 2018 & I didn't take delivery until 09/22/18
    • With 34.5K on the odometer, my 3yr/36K B-to-B warranty will expire in 10 days!
Diesel Particulate Filter won't be covered by Powertrain Warranty but rather by Emissions Warranty:
  • Our vehicles are less than 8500 lbs so are classified in the Car and Light Truck category
  • Therefore All Emissions parts have a 2yr/24K Emissions Warranty
    • If you are lucky to be in California, all parts are covered 7yr/70K
    • All parts covered are listed on Page 20 of the Warranty Guide (attached below)
  • "Certain" vehicle Emissions parts have 8yr/80K Emissions Warranty:
    • Catalytic converters
    • Electronic emissions control unit
    • Onboard emissions diagnostic devices
    • Battery Energy Control Module (BECM)
I can't see how/why the DPF shouldn't be listed as one othe "Certain" parts, but it isn't. Not really sure I like this (I think we are getting screwed as the bigger PowerStrokes carry 5yr/50K on all Emission parts) but this is how I read the Warranty Guide.

My Plan of Attack would be:
  1. Play stupid and tell them this is covered by Emissions Warranty and the DPF is listed on Page 20
  2. If they push back that Page 20 parts are only 2yr/24K warranty, then ask for an OASIS report for your VIN
  3. Cross-your-fingers that your truck is < 3 years old and covered by 3yr/36K Bumper-to-Bumper
    => Pages 18/19 clearly state 3yr/36K B-to-B exceeds the federally mandated 2yr/24K Emissions
    => Warranty starts on date vehicle was sold and not manufactured
    => Hopefully with your very low mileage, yours was a 2018 leftover that wasn't sold until 2019
  4. Purchase a Flood ESP online and don't disclose your current dilemma
This is yet another reason as to why I purchased an Extended Warranty ESP from Ford.

I would hope given this truck's history with your dealership that they wouldn't screw you over and try to make things right, as I would be pissed if I bought a used truck from a Ford dealer and the DPF grenaded at 18K miles = something went wrong and they knew this truck was a problem child. Maybe a discussion with the Sales Manager and GM is warranted? I wouldn't back down... Up to GM + Sales Manager + Service Manager + Parts Manager to act as a team to make things right on this used "low mileage" vehicle their dealership sold you.

Good luck and please let us know how you make out!

I suspect something is very wrong with the place that did your service. They can't replace BOTH turbos since the truck only came with only one turbo, yes only 1 not 2. Try a different dealership and never come back to the same place.


I assume that you're in USA, Ford covers the emissions for 8 years/80k and DPF is one of the items that is covered under emissions.

When service guys slap you with a powertrain rate quote for emissions work; time to change. Not sure if it was the same place that did the recall but going to different place would by my

If you're out of warranty, you might find a shop to just delete the DPF and never have to worry about emissions.

@Stroki - that was what I initially thought also until I dug into the 2018 F150 Warranty Guide....

On Page 18, note that only "certain" parts are covered by 8yr/80K Emissions Defect warranty:
  • Catalytic converters
  • Electronic emissions control unit
  • Onboard emissions diagnostic devices
  • Battery Energy Control Module (BECM)
and everything else (Parts listed on Page 20 above) is 2yr/24K:

but clearly notes Ford's 3yr/36K Bumper-to-Bumper surpasses this mandatory federal coverage.

I should have stated the turbo was replaced twice. I misread the report. I have some questions but first thank you so much for the information. Service manager is dodging me, surprise!

Other information:

Truck was not purchased at this dealership and sold as is. I had a mechanic friend inspect it and drive it several times. I opened it up on the highway 3 times and also took it home first. Tough to believe a brand new diesel truck would have catastrophic issues. I also was relying on warranty which up until now has covered all repairs. But here we are.

1. Will the OASIS report have both sale and manufactured date on it? Will it have all the previous issues from former owner?
2. Assuming that the 3/36 is rated by what comes last because I have 50k on it.
3. I’m in South Texas, no CA advantage.
4. Showing up unannounced this pm or tomorrow am, where do I start?
5. Part is ordered, should I walk away or keep fighting.
6. They said it is drivable but will start to lose power. Drive it and get coverage?
6. I’m a retired teacher so I have the time and motivation to be a huge nuisance. Also know the owners but I’m really trying not to be that person.
Again, thanks!

@SSBL - thanks for filling in missing and since purchase details, as it helps fll in some blanks.

1a. Will the OASIS report have both sale and manufactured date on it?
It will have the date it was sold/entered into service
Manufacture date might only be on window sticker & Driver's side door pillar
1b. Will it have all the previous issues from former owner?
Yes, any recall work performed by any Ford Dealer will be documented in VIN-specifc OASIS report
2. Assuming that the 3/36 is rated by what comes last because I have 50k on it.
If you are over 50K now, then you've exceeded mileage part of the 3yr/36k (which ever comes first)
=> You only mentioned mileage when your purchased (18K) in your original post

With this new info, I don't think you have any cards to play with existing Ford Warranty coverages, but I'd still have a conversation with the Sales manager to see if they can discount parts or service unless they are being firm on "as-is" sale.

Thanks for correction. I was under assumption that emissions goes past 3/36 so from booklet 8/80 looked about right. Friend of mine had his SD DPF warranted past 70k but I'm not sure who warrantied.

SSBL,

Ouch, feel your pain from the service you got.

I concur jmperlik points

Since you are out of warranty. You can try getting local shop welding the crack, depending on the crack it might be possible..

I personally think you can find a shop to delete the DPF and save $1,000. With deleted DPF, never have to worry about adding DEF fluid or any other emission related problems and get more power and gas millage. Not sure if now Texas is doing tests for diesel emissions or not.

I’m sorry. I don’t understand. “Delete” DPF? Like have it removed from service record or from the vehicle? Or both, lol. I thought DEF was necessary for the engine? It’s just an emissions issue? I need to understand more. TIA.

Basically, remove from vehicle/operation completely by punching a hole thru it (filter) or replacing it with new hollow pipe in its place; it does require programming in order for engine to run properly.

DPF is Diesel Particulate Filter; deleting the "filter" part, everything else can stay in place. Other way of explaining is that the "filter assembly - aka DPF" can stay in place but the inside guts get to be removed.

If you just remove DPF without programing new software then truck isn't going to run. If you just program and keep program DPF in place truck is going to very slowly loose power until DPF fills up with sod(dust particles) and then completely stops once it's plugged up, depends on driving habit anywhere 5K -50k before getting plugged up.

If you are going to run over 60 horsepower tune than your truck will puff black smoke during acceleration that you might have noticed on the tractor trailers.

In order for DPF to be cleaned up from sod in the filter during the normal operation; vehicles go into "regenerative mode" and burn up the sod. Burning up the sod is done by putting fuel in the exhaust and cranking up the heat on the exhaust; the heat travels thru turbo before it gets to DPF. It heats up to the point that heat can melt the turbo during regeneration. Regeneration puts extra heat stress on the engine.

When deleted, no regeneration is needed and engine isn't cooking or looking at exhaust any longer.

DPF is purely emissions thing nothing to do with engine performance.
