More power, a danger to warranty?

It's the equivalent of giving the dealers wife a rebore and still expecting a complimentary coffee...

I would be interested in help knowing what you are speaking of! Enlighten me, please.

Before tuning the engine or gearbox I would make sure the engine has no excessive oil consumption.

Tuning will void the warranty.

Dealers don’t like to tell you that because there also is no reason to pay for expensive inspections and oil changes at the stealership after tuning ?

Maybe there are a few dealers who are cool with the modifications and still give you warranty for anything except the tuned parts but don’t ever expect that.

It comes with free feet pics if you get a tune through them

If I boost my power output on my 2023 supra 3 L automatic either by tuning or by aftermarket parts, how likely am I to negatively affect my warranty? Thanks in advance for any thoughts

Eat paint chips as a child?

Did you really just ask this?

Does your supra have a tundra engine? Cuz then it may need to go back lol.

definitely will cause issues if you have any issues with your engine after. My Toyota stealer says as long as whatever you modified isn’t being claimed on warranty for an issue your good.

I’ve tested that a few times too

Ok so it appears no one is really answering his questions, so I will (nice old dad that I am)...

YES.

Once you add something of your own to your car, all warrantees related to it are now void. Examples are:

1. You add a wing and drill holes into your trunk. It starts to leak and shorts out the electronics in your trunk. Toyota won't fix it.

2. You flash your car to produce 1000 hp. The transmission fails or the engine throws a rod. Toyota won't fix it.

3. You swap out a suspension piece with a race version and the race version fails causing you to crash. Toyota won't fix it.

I've been in for "extended" warranty service (which is the lowest hassle level of service you can get) with stock AND modified cars. You can almost tow a car in on fire with a stock car and a warranty will cover it. In my case, wife's car needed an ALL NEW transmission - bill was $14k. Covered.

BUT with even on a lightly modified car - I've been denied service on marginal items... they claimed lowering springs "affected" the radar cruise control, the latter was malfunctioning before lowering. Even had BMW back me up. The labor cost to the warranty, 2 hours. :\

Although SOME dealers will warranty work if there's no catastrophic damage - I had a BM3 flash and needed a EVAP sensor replaced under recall. They mentioned the flash to me, I confessed the car was modded, but the EVAP wasn't related per se and they didn't mention it to BMW BUT it was logged as a modified car.

So in short, if you are going to mod it, be prepared to be an adult and accept responsibility if things blow-up.
