If you've ever had any warranty work denied or your factory warranty voided, for ANY reason, this is your thread. We need to hear about it!
Please, no; my sister's cousin's uncle's brother's, stories. First or maybe strong second hand stories only.
Dont know if this is right place for this, so I will create separate post too.
As my car now sits at dealer awaiting transmission repairs, I was told by dealer that ANY repairs that may come under TSB or recall from Ford are NOT automatically repaired. Only time it is addressed is IF customer has specific complaint that leads to TSB or recall issue. This seems strange to me. I never had this approach by any car manufacturer. Typically if car goes into dealer, once VIN is submitted, any and all service needed including TSB, recall, oil change or any other "maintenance" item is documented, noted and repaired.
One of the first things dealer said to me about my car when I took it in for transmission problems was, "you are due for oil change! Want us to change your oil?" And, "your transmission fluid is a little low! Although car not having any problems relating to a late oil change (like a thrown or bent rod, lol) then why cant or wont they do the same check for TSB's and such. Especially if safety and maintenance of vehicles is the primary concern? Just saying!
http://www.ecoboostperformanceforum.com/index.php/topic,3008.0.html (http://www.ecoboostperformanceforum.com/index.php/topic,3008.0.html)
Most dealers I have worked for here in Canada do TSB's on cars as soon as they see it needs it.
I have seen many dealers refuse warranty work when they see that the problem, even if it may have been prevented by a TSB, may be caused by abuse/ modification.
I know we've all heard of it happening, but I want a first hand report of someone getting told their warranty was no good because of a mod or something.
It's a topic that gets brought up a lot on this forum andba concern of many of our. Just wondering how prevalent, or if it's just an urban legend. LOL
Anyone??

I'm like JimiJak.... Any first hand reports... especially FORD, and especially EB engines
I have yet to see an actual denial of service/cancellation of warranty here.... I'd like to here from someone who had it happen to them... not more speculation and 2nd party reports
I've had it happen to me, and I guy I work with also. For myself dealer refused to warranty. I still have factory warranty intact. My coworker ford axed his warranty. His issue was cam phasers, and the voided his warranty saying he didn't change his oil often enough on a truck that only had 20k on it. For myself had drive line whine which the dealer said was PTU and warrantied. When that didn't fixed it was a bearing in trans and they said they wouldn't submit they claim to ford due to the mods I had on my car.

Did you go to a different dealer? Its not the dealerships call to honor or not honor your warranty.
For ages we bought new F350 dually diesels for the race team every 3 years or so, the first one after the 7.3 was dropped (6.0 diesel if I remember?) lifted the heads (as they all did) and when we brought it in the dealer refused warranty claiming the K&N filter we added caused it. Went to dealer down the road (a Lincoln Mercury dealer) where we did not buy it from and they warrantied it no problem. And the second, and 3rd time as well. Then we did our own ARP head studs and no more problems after that.
Needless to say that dealer NEVER will get another purchase from us.....they lost a good long term customer, but the other dealer went up and above the call of duty. Bad dealers and good dealers.

so the mods were obvious? was it the tune or something else? did you try to flash to stock before bringing it in?

The dealer has to obligation to Ford motor to submit a valid claims. My dealer was aware of my mods to car, they warrantied PTU. And that didn't fix they couldn't turn around and say its the trans now. Especially when Ford head quarters is only 5mi's away. Ford would have sent a inspector and my warranty would be voided and the dealer would take a hit for submitting a invalid claim. Now should the repair been warrantied? I'd say yes, cause I have chalked up to being a faulty part. As I have more miles and more HP car now then I did prior to repair. But the rules are clear. If want to play be prepared to pay.

Did you ever consider the possibility that they refused to submit your claim because they would've been charged back for the misdiagnosed PTU?
Your claim was a valid claim up to the point they are able to prove the mods caused the failure.
I know for a fact that dealerships and Ford can and do honor the warranties of modded cars. I know specifically of a f250 that had been heavily modded (flash, gigantic exhaust, intake, etc), Ford was aware, and they covered
2 transmissions. The third one they washed their hands of, fair enough. 3rd time around he had a tranny built to handle the power.
Having a tuned car does not automatically void your warranty, and Ford and
good dealerships aren't running around voiding peoples warranties. In fact their policies have softened quite a bit since 04 ish.
That really sucks you were treated like that.
Sure there are always possibilities and serval scenarios it could played out for. For yourself I would say you where very lucky in your situation. But I work for ford motor, I wouldn't say where soft at all on warranty issues. It's the manufactures greatest expense. I know at my plant they investigate ever warranty claim.

I absolutely believe warranty claims are their greatest expense. I would love to know how the numbers break down when comparing modded vs stock claims.
It seems like there are some very different outcomes depending on the dealership. My suspicion is that owner loyalty, and behavior of said owner may play a huge part in the outcomes of these issues as well. I guess my point is this is not a broad stroke policy issue, it seems to be taken case by case.
This wasn't my truck and i wouldn't have faulted ford if they had denied it, I'm sure you're aware of the crazy shite some of these diesel owners do to their trucks...this was a classic example. In fact I think Ford went above and beyond in this case.
I just hope if I'm ever in this situation with the SHO, I get similar consideration. Every dollar spent on vehicle purchases and service goes to Ford. If my mod was proven to cause the issue, I'd take my lumps. But for them to say modded car = voided warranty without any investigation as to the cause of the failed part is a bit hard to swallow.
crash, why didn't you try another dealer?
and why does the one dealer know about all your mods, did you tell them?
seems to me, you working directly for Ford makes your perspective, and resulting behavior, different from what most would probably do...
They dealer chose cause I personally know the service manager. And do believe he did everything he could for me in my situation, without risking penalty to him self. So yes he was apprised of everything I did to my car, he was really in between a rock and hard place. The only he could do is give a great deal on the repairs, and from what he showed me for any one else it would have been double. And quote his words exactly. " if ford seen my car they'd void the warranty on the spot."
As I am a employee I will keep my opinions about Ford brief. Its not the place it use to be. Even with my coworkers ecoboost f150 with 20k on a cam phasers going out, which is well known problem. They wouldn't warranty because of varnish on internals, and he claims he changed the oil every 3-5k. And after working there for 28yrs you get to know a lot of people inside there, and nobody could help him. And he was told if he continued pursuing they'd just void his warranty all together.
I know all about magnus moss act. But Fords don't have to prove nothing, they got deeper pockets and better attorneys.
There is something very important everyone needs to take from crash's story.....maintenance! Make sure you keep excellent records if you don't have it dealership serviced. Make sure your exotic oils and fluids meet all of Fords standards because that is one thing I know for sure will get your claim denied. I find it simpler just to take my stuff to the dship.....have them do the labor using my fluids.
Also what I have heard (though rare) is a dealer that denies a warranty and charges the customer AND submits for warranty reimbursement. I have never seen it personally, just was related from an ex-employee. Hope that is very rare.

This is what I do I buy the oil and filter and pay them to do the labor. $14.95 is cheap labor for an oil change. Plus when I go to sell the car I have proof of all maintenance done on my car which is always a good selling point.
So we've heard from crash and about crash's friend, a couple of un-honored tsb's, and I've been pm'd with one instance of a dealer basically "warning" a customer to make sure they have their car back to stock when they bring it in for work.
This thread has 530views.
Happily, this is the response I was hoping to see. Please, if anyone else has had warranty work denied due to mods, please share so we can get a more accurate sense of this topic's prevalence.
This isn't Ford specific but when I modded as a mechanic for GM and Chrysler Dodge Jeep. I had only seen all few cases of voided and refusal To do warranty work. Most cases where due to extremely modded vehicles or horrible maintenance and or neglect.

Returning the car back to stock for the purposes of troubleshooting is pretty common.
http://www.ford.com/resources/ford/general/pdf/2013Warranty.pdf (http://www.ford.com/resources/ford/general/pdf/2013Warranty.pdf)
sadly, i may be testing this topic soon.
engine essentially blew up, i guess, with oil spilled all along my street. i was lucky it happened close enough to home that i could coast and park it. only thing it has is an unleashed tune, nothing overly aggressive. i haven't even been running it alot lately, mostly been stock. I did get the oil changed a few days ago, i have my receipts, and i'm thinking that shop may have done something wrong. i've used them before and they've been good, but when i checked my oil a couple of days ago it was very low, especially considering it had just been changed. i called the owner/manager and asked them if they put the entire 6 quarts i brought into the car. he talked to his tech and the guy said yes. so i added another quart and check the level and it was good. then last night the whole blow up thing happens!?! I spoke to him today to let him know the situation. he seems pretty confident that they are not at fault. i told him i will have it towed to the dealer and see what their diagnostic says. He's a cool guy and has given me good advice, he even loaded my tune to the car. But techs make mistakes sometimes.
the car was very recently at the dealership for servicing, actually its been at the dealer alot lately which has me a little frustrated, and i have all the records. I've been trying to get all problems solved before the warranty ended. this particular dealership was really good in the past, but their service dept has fallen off in the last year and their are different people working there than before.
we'll see what happens. if any of you have any advice, please let me know.
i did return the car to stock, as all the electronics are still working so i was able to load it...
I like when people say all it has is a tune lol!...you realize thats everything in this car......if all it has is a "tune" why bother returning to stock?...sorry i have to play devils advocate....i wouldnt be suspicious of the unleashed tune...i used to run one and would run it again...but the torque increas is dramatic to say the least with a "tune".
Yeah i know all about the magnusson moss act and how the onus is on the mfg to prove the mods caused the failure....but i hate sticking up for the big guy corporation but id be ok with them making buyers sign a release waiver saying if you tune you most likely lose engine and drivetrain warranty ...just like the guy you buy the tune from has disclaimers protecting them from the failures of the tune they sold you...they dont want anything to do with the liability of your thoughtless quest for power
Its unfortunate for the mfg that not only are they on the hook to fix peoples cars that suffer failures due to neglect and poor maintenance but the also have to be on the watch for people trying to dupe them and perform fraud...after all thats why you returned to stock. So the heavy modification hopefully goes unnoticed.
do you have any idea of what you're talking about?
there is no heavy modification! basically all my tune did was increase throttle response. i specifically wanted and received a conservative tune w no transmission shift programming at all. no 3bar map, meth, etc...
anyway, these engines have been shown to make way north of 500 HP quite reliably.
like i said, if you read my entire post, is that i believe it was the oil change that was the issue. i think the tech made some mistake at the other shop. my car has been at the dealer many times for service and i keep all records. if the tuning was causing problems, i'm sure they would have noticed.
Any visible exterior engine damage? Are you sure it blew up or did you just lose a gasket somewhere.

No i dont
So u have an unleashed tune with no boost increase , just throttle response...good for you....you are on an island all by yourself on that one
Why would the dealer try and notice if a tune was causing problems...not even on their radar for normal maintenance...and why would u remove the tune if they never said anything before?...fishy fishy
How many miles on this blown engine? F, if additional 50 hp were the cause of this engine blowing, I'm selling my AFAIC, and never buying a Ford in my life again. Anyway, I would test for the right viscosity of oil that that shop used, proper filter, and then wait for Ford to take the engine apart to see what went, before making an educated guess on the cause.
MeanKS are there any codes present at the moment? Receipts are Golden,based on your post it sounds like the tech forgot to tighten the oil drain plug or filter. Z

He brought them his own oil so i have to assume he used the viscosity in the owners manual.....and i wouldnt worry about the hp increase but the massive tq increase that the "tune" delivers which is can be 100 ftlbs for a 2 bar tune and 150 ftlbs for a 3 bar at the crank
I guess the reason I say to test the oil is just to make sure the oil shop actually used the oil he brought in, and did not make mistake by putting something else in. Which would not be surprising if there was miscommunication, or someone was daydreaming on their job.

i've had this tune for nearly 2 yrs. makes no sense that it would all of a sudden blow the engine.

sorry Cro, that wasn't meant for you...
im not sure why tou think a tune has to cause a failure immediately....after 2 years the constant extra stress could most defintely cause a failure....but since your conservative tune which has no extra power delivered makes you safe i guess

of course there was some HP and TQ increases, but not even close to what you state.

How do you know how much tq increase?...if u have a typical 2 bar tune u do have around 100 ft lb increase in tq at flywheel
I guess no sense in bickering around, let's just wait and see what the dealer says. How long will it take them to take the engine apart, what they said? i remember this one story by one of my buddy's when he took his car for transmission fluid change, and on his way home, half way, the trans pan came halfway lose and almost feel off. Someone forgot to put all the bolts in. Lol, we still laugh about it till this day.
Feel fer ya, MeanKS, been on the receiving end of improperly done oil changes a few times before. Now, even with my trusted shop, I am used to double checking their work! Best of luck with Ford, those receipts might be the key evidence.
If the oil pressure light is displayed on the instrument cluster followed by a long history of service records and receipts especially most recent,that alone should warrant any and all applicable repairs in your favor and best of luck and keep us updated on any progress,and Btw sure hate to see this happen to anyone else on this or any other forum. Z
sorry for the delay in response.
So Ford covered the new engine, really with no questions asked, which kinda surprised me. i think it was because i had saved all my records and had been at the dealer a lot recently due to other issues. they also replaced the torque converter, again i think because i had a previous issue with a squeak coming from what sounded like one of my wheels and the dealer thought it was a transmission issue with the AWD but hadn't got around to finalizing the diagnosis.
they are not entirely finished with the car, i will have to bring it in again soon. they still need to fix the auto park controller (previous issue). also, the car doesn't feel quite as strong as before (i'm talking w/o any tune) and the gas mileage is worse (15.5mpg). i also hear a whistle coming from the engine (assume its one of the turbos) during WOT in first and second gear.
i think the lack of speed is probably more due to the transmission than the engine (maybe) i really don't know, but its very slow to kick down making passing on the highway less than effortless the way it was before.
does anyone have an idea of which 3.5 they used? is it a gen 1 (2010-2012) or gen 2?
obviously i'm more wary to tune now, although i thoroughly believe its was a bad oil change that was the culprit, but i want to enjoy my car like i did before.
so we'll see...
Two steps forward ... Hopefully they used the latest version of the engine, but it's hard to say, I imagine it has to be compatible with the PCM and all wiring harnesses, so they would minimize any spec differences between old & new, if such differences exist. Might have gotten the updated valve covers with it, easily checked :)
The trans may need a teardown, or the PTU (or RDU) may need to be replaced. Can't get any more definite than that at this point tho, I don't think ...

thanks SHOdded.
anything specific i should do or ask?
i know i'm going to have to start all over with new plugs, 3 bar MAP, etc; but i'm not going to start any of that until they complete their work entirely...
I would mention the symptoms you have described: the whistle and the lack of power. Both could point to hoses not connected or tightened down properly, a common issue when doing more complex work in the engine bay. Also ask them to verify that the turbos and PTU are ok (no leaks). Since you have an MKS, there's a higher likelihood that the PTU IS ok from what I have seen so far, but ask anyway.
Did they install a shortblock or longblock, do you know?
no i don't. what is the difference?
i have the service records. is there something i can look for to see which?
Short Block
https://en.wikipedia.org/wiki/Short_block
Long Block
https://en.wikipedia.org/wiki/Long_block
If the valve covers are composite rather than aluminum, they likely put in a longblock. Put up a pic of the receipt (with personal info hidden of course), maybe there's an indication there, maybe not. What year is your MKS btw?
2010...
Meanks glad everything is working in your favor,check out this link from Lincoln,is your MKS a job 1 or job 2 ? and best of luck.

I am currently going back and forth with Ford about their warranty. My 2016 ecoboost has clearcoat peeling on the bumper, and has 20k miles on it. Ford is claiming that this is impossible, but the service station even agrees that this is ridiculous and should be covered. Such a hassle to deal with.
Are you dealing with the dealership or Ford?
I had warranty work denied by the Dealer and Ford. Threatened a 93A law suite and they paid me back. My F250 SD died while out one day. Had it towed to ford dealer. Chafed wire shorted fuel pump. They said repairing a chafed wire was not covered under ESP . I told them ESP specifically stated wiring harness. They said only if they replaced the whole harness LMAO . I paid the $300 to get my truck back then sent them a 93A letter. Two days later they called and said come get your $300. IMPERIAL FORD Mendon, Ma.
Same truck "death wobble" took it back 3 times, told they were aware of the problem but had no fix. I hired a Magnuson Moss act atty free of charge. They sued Ford got $8,000 gave me $5500 and kept $2500 no defect on title. Im guessing they do this all the time and get away with it because people don't pursue them.
Unreal. Just unreal.
Yeah, gotta crack the whip sometimes. Normally people live with it or take a hit on tradein.
Sorry to wake an old post however I came across this thread and I thought I could contribute.
To the OP's original question, "Has ANYONE EVER had warranty work denied by Ford?" My answer is ABSOLUTELY!
I have a 2017 Lincoln MKZ 3.0 TT Black Label. I am not the original owner. I bought the car with just over 52k miles on it. That means the 4/50k bumper to bumper was expired however the 6/70k powertrain warranty still applies. For those who don't know the manufacturer warrant follows the vehicle not the owner.
I was driving the car and check engine light came on and it was running rough. I pulled over and checked the codes (I carry a OBDII scanner with me). I got P0302 and P0305 (misfire on cylinder 2 and 5. I reset the codes to see how quickly they would come back. Fairly quickly the check engine came back on and P0305 was the fault.
I took the car to the a Ford Dealer (Lincoln dealers are further and more rare). Initially asked for the repairs required for the misfiring and "the works" oil change and service.
They pulled the cylinder 5 spark plug and the side electrode was mostly gone, the plug appears to be to be blackened don't know if it was cleaned at all but still has an oily sheen on it (obtained from dealer later). I had to wait a day for them to get tooling to pressure test the cylinder and then another day because the tech called out. Basically they found not compression on cylinder #5. They borescoped the cylinder and found metal pieces (likely from the plug electrode) and scoring of the cylinder.
They called to tell me I need a new engine, good news it would be covered under my powertrain warranty. They just needed to submit the parts list, but they did say they really didn't have the time or ability to do that work but the service tech was like, "but you didn't know that, I probably would have told you had I known". Keep in mind the appointment to drop off the car was booked online which they apparently say doesnt work but they would check it out anyway....because again as the service tech says, "you wouldn't have known that".
Anyway, long story shortened, the factory representative tells them if the spark plug caused the failure it is a maintenance item and therefore isn't under warranty. The dealer call to tell me and gave me the Ford Customer service number which I called. Spoke to a rep who had to look into the issue. Came back and said the same thing and when I said there is no way that they know for certain that the spark plug caused this, they don't know what caused the PLUG to fail. They said they would have Engineering evaluate it and days later I get the same result, the plug failed and therefore it is not covered under warranty.
They never inspected the other plugs, never pulled the heads to look for any other issues (didn't even ask as an option which I would have paid to have done). Also these are the factory plugs the mileage is just over 57k and first plug replacement by the manual is 100k. My take is the plug failed due to some other issue. However they are denying my warranty. So yes, it does happen and I am working to fight it but options are limited and the cost out of pocket goes up.
This is current and ongoing so still working through it. Hope that answers the questions and maybe someone else out there has seen this or finds this in a search.
Ford is bleeding money badly just like most manufacturers. So they are only gonna get tougher on all warranty work.
Look at the owners manual for spark plug service interval on your vehicle if no service replacement required on the plugs until later, then plugs likely are original. Also read the warranty supplement for Ford's warranty exclusion reasons. Seems like Ford also has customer service advocates, or they once did. I had a discussion with one of them in late 2000's about a dealer and a poor repair
If you have a good case, go to small claims court against the dealer, or what ever entity is denying the warranty. No attorney, jus a judge and presenting the facts, has worked for me before. Too bad about your situation, fires me up Ford does sometimes, but it is all I buy. Good luck, post what happens.
posting on ford's social media page may get you positive results in phone calls to corporate are not working out. were the plugs Motorcraft/Ford?
keep up the good fight.
