Enjoy wearing your tin foil hat.

 

They can absolutely void your emissions warranty. The stated life is 30k, as it's a copper plug. If you don't change your plugs, past their stated effective life, they will not spark as much, unburnt fuel will go into the cats, and destroy the catalyst. Sooner or later if you get a p0420 or p0430 they can absolutely deny emissions warranty and 8/80 coverage on the Cats, which are spendy as hell. That is exactly why they even list it in the owners manuals on the 4.0's at the 30k maintenance, and they stop the free maintenance at 25k for a reason. There's even an special notation in the manual that expressly states the lack of spark plug maintenance voids the emission warranty...

 

You have a copy of this quote or a link to an official document?

I'm not saying that you should skip the 30K spark plug replacement, but lets say you don't do it until 40K miles. Do you think they can tell that you went an extra 10K? Homey don't think so.

 

It's a good thing nobody pays you to think.

The Toyota Warranty and Maintenance Book... it came with the truck if you bought it new. If you don't do it until 40k, you are already out of factory warranty anyway, and you have the burden of proof to prove maintenance was done at the stated interval. You would lose every time if you do not have a repair order or receipt of purchase of parts for maintenance dated on something.

Page 41 sub-text #4

It is expressed and implied... If your cats fail, you get to buy them. And spark plugs are like $5 a pop...

I don't work for Toyota but I know how cars work, I know how warranties work, and I know you would lose every time for negligence of maintenance if there was a cat failure, and it has nothing to do with the M/M act you quoted like the bible. It's not an aftermarket item so that does not apply. It's a scheduled maintenance guide and warranty guideline. That's how warranty policy and procedures work.

 

Ouch maybe just post more tin foil hats since that's your standard response when being proved wrong.

 

How about this quote from your very own reference:

Page 29, Your responsibilities.

The bolding is mine, for emphasis.

 

However, damage or failures caused by
lack of proper maintenance are not
covered under warranty.

I like how you didn't underline that part... like it's not there. Cat failure due to lack of spark plugs are not covered under warranty. You still have the burden of proof that you did the maintenance. You are liable for repairs, not Toyota

 

You would be suprised what I get paid to do Nub.

So what you are saying is going over the 30k by a few thousand miles is going to void the emissions warranty because they will know that you went over due to a lack of documentation even though they state that:

Toyota will not deny a warranty claim
solely because you do not have records to
show that you maintained your vehicle.

OK. I guess we will agree to disagree.

I guess I haven't learned anything in my 45 years of working on cars and trucks. Cat failure is not caused by not changing the spark plugs within reason anyway. It could be caused by running too rich and dumping unburned fuel into the exhaust, but sometimes it is other factors such as fuel additives that are not cat safe. Even then it doesn't happen over night.

If you neglect the maintenance to the point your getting unburned fuel into the exhaust then that is another level of stupid. That is not what I am saying at all, never did.

You guys are just trying to pick an argument just to argue.
Good luck with your tin foil.
I'm done with you both.

 

Its amusing how stupid you are. First of all where is the proof that you can not do the recommended maintenance on a vehicle and still be covered under warranty? You have not shown any proof of anything, you just cling to the Magnusson-Moss Act and say you don't have to follow the REQUIRED maintenance schedule. This is false, you do have to follow the manufacturers required maintenance schedule in order to keep your warranty intact. You also keep saying "well if I just do the plugs a few miles over how will they know", no one ever said that they would know and void the warranty because you were over the 30k miles, what was said is if you fail to do the maintenance a failure as a result will not be warrantied. And lastly I don't think you even understand this whole tin foil hat thing that you cant seem to avoid reposting. You would actually be the one wearing a tin foil hat as you are going against the norm, in this case Toyota, similar to how conspiracy theorists go against the government (another large corporation). But you're done with us because you have worked on cars and trucks for 45 years so you must be an expert on everything car and truck and anyone who is wrong wears a tin foil hat. Keep not recommending routine maintenance on vehicles, that must be where you get all your business after peoples cars break down and aren't warrantied.

 

I don't think I've ever seen anyone challenge JimmyH in this fashion on this forum before.

That's like challenging DoorDing. What happened to that guy anyway?

 

I hardly think jimmy is stupid I have seen him help dozens of people just in my short time here.

What is stupid is arguing with people on the internet excessively.

A difference that makes no difference is no difference and no one fucking cares who is right unless they become emotionally attached to their opinion which no one cares about anyways move the fuck on.

 

I can't speak for Toyota, but since 1990 I have worked in GM service departments and I have rarely seen a warranty claim denied due to lack of maintenance. It would have to be very obvious such as oil that hasn't been changed in years with no paper trail of the work done and the engine fails because of it. Again, I'm not saying claims can't be denied, I'm just saying it's rare in my experience with GM. I personally would follow the owner's manual just to cover your ass while the truck is under warranty.

 

Arguing on the internet is stupid, most of the time. But when someone is recommending something that could potentially cause an issue for another member, then its a problem. I understand that its his opinion and everyone is entitled to their own opinion, but in this case he shouldn't tell someone its ok to skip regular maintenance and expect to get warranty coverage.

 

Happens all the time in the Subaru world. Now were talking turbocharged vehicles that are usually purchased by kids and beaten with no maintenance being done, but in this case its relevant. Subaru denies claims for engine failures if they can prove that the owners were not doing the proper maintenance. Toyota may or may not do the same but why take the chance, plugs are cheap and when changed regularly can keep your MPG and power where it should be.

 

And you are right stupid was a bad choice of words, haven't had my coffee yet so I/m a little testy. He is not being stupid, I just don't agree with some of his statements. But its a public forum and everyone should form there own opinions anyways.

 

We actually sold a WRX a few years ago and the kid that bought it abused the hell out of it and damaged the engine. The car was still under warranty and Subaru denied the claim. No maintenance records BTW.

 

This is why I sold mine, the EJ255 and 257 engines are prone to ring land failures at even stock power levels. Subaru also claims its normal to burn through a quart of oil in 3k miles.

 

We're doing head gaskets on a non-turbo in our shop right now, but it's a high mileage 2006 Impreza.

 

Nice to hear from somebody that actually is in the business!

 

So the question is, to change or not to change spark plugs at 30k, lol
