Guide to spotting aftermarket parts and possible consequences

[_veloci_]

Also depends on the dealer. I've had dealers that were pretty cool about saying there was no mods on the car to the warranty claims office if it is a completely separate issue, i.e. window switch broken etc.

Good stuff. Just to be clear though, from everything I understand modifications cause specific things not to be covered under warranty, but don't void the whole warranty. If I install an exhaust and my left headlight fails that would still be covered.

Exactly. Thee needs to be correlation between the failure and modification in order for the warranty to be affected.

So when i was considering an aftermarket exhaust just after I purchased my 2019 SCAB a little over a year ago, I was concerned about warranty consequences so I contacted my dealer to ask if there would be an issue with me installing it. After speaking with someone in service, she was kind enough to send me this Ford document that covers alot of aftermarket parts and their possible effects on warrantied parts. Its meant to be used as a guide by Ford service people on how to spot aftermarket parts and how they can affect different parts and essentially give Ford ammo to void your warranty. Interestingly enough, when I asked if I purchased the "Ford Performance" exhaust AND had it installed by a Ford technician if it would void the warranty, the answer was still YES.
I think you will find it interesting and useful, my apologies if it has already been posted before and is old news. I also hope that its not a top secret Ford document and I dont get in trouble for posting it.

Enjoy.

To clarify, Ford Performance products do not void the manufacturer’s warranty; they are just covered separately under their own warranty. Here are the details:

So just got off the phone with my local service tech. According to him, as long as the tune/modification is installed by them there should be no issues with warranty Planning on droping an MPT tune in. Nothing in writing though so what do you guys think? Sorry about the thread jack.

anyone with any common sense should be aware......modify any part of your car, and you should expect to forgo your warranty coverage for parts related to your change. The dealer has every right to do so. There is very little you can do to "hide" your modifications.

Those who get upset when warrenties are denied have nothing to be upset about. It is a risk we all take.

Does the ignition counter reset only on flashing ECM or also if battery is disconnected?

There is no way to hide flashing of the ECM. No amount of ignition cycles will hide the time stamp. If the ECM time stamp does not match what ford has, you are busted. They cant tell what you did to the software, but the know you did something, and that is enough. When you bought the vehicle, you signed an EULA for the software in the car and agreed you would not modify it. PERIOD.

Nothing in writing is a red flag.

Yeah official Ford Performance products should NOT void the warranty. I plan to keep mine stock but it shouldn't void the warranty if you add a FPP exhaust to your truck. I have to say the stock exhaust on these trucks sound bad very bad.

That is completely incorrect information from that technician/dealership.

If you experience any powertrain related issue/failure than can be attributed to the aftermarket calibration, it will not be warrantable.

If it is a significant failure, like a melted piston, rod through the block, etc Ford will often dispatch a Field Service Engineer our to inspect the vehicle. At that point they will determine the failure is non-warrantable due to the aftermarket calibration.

Tuning your engine is a kiss goodbye to your drivetrain warranty. People deep down know this, but choose to ignore it or pretend it isn't the truth for some odd reason. Case in point.
