Mods That Will Not Void Warranty

[Tenbrooks]

What modifications can be made to a new Mustang GT 5.0 that will not VOID the factory warranty? I expect most anything under the hood will void the warranty such as replacing the factory air intake with cold air intake, turbos, superchargers, tunes, etc. but I'm not certain. I'm not interested in cosmetic changes that would dress the car up but rather mods related to upgrades in suspension, exhaust, oil-air separators, etc. I expect Ford is not willing to stand by their warranty for a modified car and, I don't want to VOID the warranty just yet. Thoughts?

You can add a cold air intake. Tuning is what would void it.

I'm sure you can make a decent street car without voiding your warranty by buying ford performance parts and having a dealer install it for you. Also from what Ive gathered one of the biggest factors, if not the biggest is how lenient your dealer is on performance parts.

If you buy one of Ford's suspension packs and have a dealer install it, I don't think there should be any issues if a problem was to arise. Also, supposedly they are releasing the Performance Packs for 2018+ so you'll be able to bump up the power under warranty.

You could also die tomorrow. Mod the car, use a reputable tuner, and don't look back. Have fun.

Nothing you do will "void" the warranty. If something is modified, that particular part will not be covered for a warranty repair. If you tune the engine, it's probable that an internal engine failure will not be covered.

Manufacturers cannot, by law, "void" their warranty. What they can do is deny a warranty claim if they can prove a particular modification caused a failure.

I have had many repairs done under warranty on my last 3 Mustangs. All were tuned, but none had any sort of internal engine failure. I did have a cracked intake manifold, and it was replaced under warranty. I think I had a CAI installed at the time.

I also had a Steeda suspension on my last car, and the real wheel bearings/hubs were replaced under warranty.

Ford dealerships WANT to do the warranty repairs, it's a large part of their financial bottom line. As long as nothing is done to the car that clearly causes a failure, as long as you have a good relationship with the service department, everything will be taken care of. They couldn't care less about most mods, they just want to do the work and get paid.

I came home to 4 different letters in mail yesterday about extended warranty. One I thought was maybe a recall notice so I opened it last but after seeing the first 3 were junk I had already pegged that one the same

Yes, I got one last week asking me to verify my VIN.

So, I gave them the VIN of an 89 Probe that I sent to the crusher in March and asked about a warranty.

Never had someone hang up so quickly.

I think some of this is also dealer to dealer. At some dealerships, if they find an altered suspension, they won't work on the car, period. Others, as long as the mod did not cause the failure, they will warranty a failure. Its hit and miss.

They keep calling me about my 2011 GT that I traded in 2014.

Cold air intakes will not void the warranty. Especially if you purchase ford performance or rousch intakes.

Most ford performance parts are covered as long as its dealer installed.

My warranty specialist was explaining that ford is actually pretty lenient about modifications within reason... They basically assume that all mustang owners modify their cars. The only time they squawk is if the mod was a contributing factor to a part failing, and most dealers will just refuse to work on the car until you return it to stock then they will cover the car... Its very rare that they completely deny coverage.
Also its illegal for a manufacturer to refuse to honor a warranty unless they can prove the modification caused the part to fail.. So a dealer cant deny covering your engine for bad crank bearings because you have a catback.

Any exhaust modification after the resonator will not void the warranty. Some dealerships measure it after the downstream o2 sensors.

So basically any catback will not/should not void your warranty.

The warranties are also broken down into subwarranties

So there's the overarching powertrain warranty then thats broken up into the emissions control systems, EFI system, and engine mechanical, drivetrain etc warranties...

Also. I have replaced my tires with other brands hit a pothole and the replacement wheel and tire was covered by the wheel and tire warranty. Its not specific to,brand.

Headers are complicated. Because they are part of the engine mechanical warranty though they are emissions related. Running headers Will probably void the engine warranty. I know on the gt350 they're very strict on that.

My warranty guy also said doing the Roush stage 3 automatically voids all the powertrain warranty BUT Roush comes with an extended warranty that takes over your powertrain warranty... Now here's the rub... The Roush warranty covers the ROUSH parts from defects... If the supercharger causes your engine to blow they cover it...

If your axles blow while doing a drag launch, not covered.

All warranties are automatically voided if the car breaks at a competition racing event.
