voiding your warranty

Be aware the car companies are trying to change this.

They don't want people effing with the software of self driving cars in the future.

I'm not a lawyer, but I believe your current 4Runner is fine.
 
Chevrolet is already doing it with Vettes and Camaros. Reflash the computer, and poof no more drivetrain warranty.
 
The short answer is it can but not the entire warranty. What this means is that the warranty claim can be denied if they can prove (very grey area on what this means and how much proof they need) that the modifications made to the truck caused the issue and obviously any factory parts that you swapped with aftermarket will not be covered. It WILL vary between dealerships and situation on what they will or will not cover.

Example: I have a lift and larger tires so I do not expect them to cover the aftermarket coils, wheel bearings, CV joints etc however I do expect that they transmission and engine issues would be covered. They could argue that the modifications put more stress on the drive train and attempt to void that portion of the warranty but I doubt it.

In regards to what [MENTION=92067]ic0517[/MENTION] said I have heard companies are cracking down harder on ECU modifications and that it is becoming much harder (if not impossible) to hide the fact that an ECU has been reflashed (Specific examples are on the new Duramax engines and Audi's). If they are finding you flashed the engine I am hearing they are voiding the power train warranty completely. No specific examples of this but I believe it and think they are well within their rights to do so. The good news is there are no tuners that I am aware of for our Engines so no worries for that one.
 
Nope! it only voids the components that were replaced with aftermarket.
Ex; Shocks, Springs, Control Arms...
Not exactly true it can extended to components that can be directly affected by said aftermarket components...
Manufacturers are well known to erroneously deny warranty.It's like they play 6 degrees with you car. I would not be surprised to see a Manufacturer rep explain his conclusion that you heater core failed due to your aftermarket lift (extreme and a bad example but hey)

From my professional standpoint I think it's the right thing to do. Personally I wouldn't want to be responsible for a machine I designed that has been modded in a driveway by some weekend warrior that is three beers shy of a twelve pack. You mod it and you own the mods and everything that mod can influence. We have enough trouble (and I'm sure Toyota does too) keeping the people TRAINED to fix it (dealers) from effing the machine up.
 
You can fight the ‘non-warranty repair’ bs that the techs will throw at you. I did it w/my FJ when the CV boots were leaking grease. They tried to tell me that the Icon aftermarket suspension caused an “extreme angle to the CV axle and that is what is causing the leak.”

I merely looked at him and told him to get a ruler/measuring tape and let’s measure the distance from my CV’s to the ground and go out on the lot and measure a stock FJ’s CV’s. He didn’t care for that too much, and after talking to the Service Manager and having him pull up the M-R Act they agreed to replace both CV axle’s on their dime. (FWIW this was the last time I went into McGill Toyota of Katy for anything).

It may also help to go to another Dealership and get the work done also. The current Dealership I deal with is the same franchise; Don McGill, but in a different part of town. The General Manager has a ’10 FJ that’s lifted so he understands the trials/tribulations/work that goes along w/having a modified vehicle. They never turn down an opportunity to replace parts/make repairs to Warrantied items.
 
My local Toyota dealer will install a lift and will warrant it just like factory. They specify that the warranty is only good there and other dealers may not honor it if a cv or other related item goes bad. If you are just using a simple spacer lift they may not even notice it especially if it is black and looks like it belongs there. A full on suspension with reservoir shocks and wild colors would stand out like a sore thumb. You most likely will never have a problem with a mild lift. I ran my 03 4runner 11 years with a Daystar spacer lift with zero problems.

I'm still shopping for my 4R but plan to do a small lift 2-3" to allow better fit of slightly larger tires. Initially I wanted the KDSS but seems like there is a lot of hate for KDSS and I thought it might make a small lift easier without the KDSS.
 
My last Land Rover Discovery ('04) was lifted 3 inches. This was the last model with solid front axle. When the front drive shaft u-joints went out my friendly dealer replaced the shaft for free but told me that they would only do it the one time.

They told me where the old shaft was disposed at (which trash can). I took it to a driveline shop and had it rebuilt with better joints and then carried it as a spare for the next nine years.

As far as Land Rover is concerned they will not warranty anything that was modified or is affected by modified components.

Not trying to bust your balls... but, your lift did probably cause the CV boots to go bad early. Why do you think Toyota should pay to repair something that is operating outside of the design specs. The increased angles causes more wear. Its just a fact.

Personally, I think people should be responsible for issues that they cause. If you want to play you need to pay...

Warranty is for the original parts operating within designed parameters. Anything else should not be covered. It's gray when trying to pinpoint related components...For CV axles... I think they should not be warrantied after a lift.

When they did replace them it was leaking from the end of boots, where they're clamped. Most issues arise (when lifted) from the boot actually wearing out, this wasn't the case, but they replaced them none the less.
