Sorry, your truck has AIDS....:(
Never seen that one...definately looks like it's bubbling from under the paint.
Christ, I guess I needed to vacuum before I took the pic....who gives a shit if there is sand inside the truck....I had a 15 thousand dollar ford and it didn't do this and I treated it a lot worse
Hahahahaha! Sorry, I don't mean to laugh at your pain, but this whole exchange is so classic. Plus, I *love* your response here.

I would suggest that you mostly ignore the comments here, but take note that the dealer will likely raise the same points, right or wrong, in an effort to avoid accountability. Best bet for you is to clean the interior BEFORE heading in to complain.

Good luck!
I agree, there are a few spots where the rust seems to be starting UNDERNEATH the paint, causing it to bubble and lift. Looks like a warranty issue to me.

This is why I want to put something over those sills, before I take more paint off... That said, the only real paint loss on mine is the driver's still, most of the paint was taking off by the prior owner. Oddly enough: it's polished bare metal. Maybe the dealer removed the rust? Certainly no bubbling here.

Take it to the dealer. If they fail to do anything, sand it down, paint it, and put something over it. I'm sad Toyota doesn't do more in this area, as people are apt to kick this area. I like to knock the snow/dirt off my shoes getting in, but can't, as there is nothing protecting the paint in this area.
The simple truth is that the paint on these trucks suck. if you look really close all over my truck there are pin points where rust is starting simply becuase there is probably a pin point chip in the paint. The sill of your truck is actually exposed to more weather than you probably realize because it is on the outside of the weather stripping and the salt from the roads will make it rust. I hate to jump along with the rest of the group here but judging by the inside of your truck you probably don't meticulously take care of the paint. Neither do I though, which is why i probably have those microscopic bits of rust starting. It's a f'ing truck. I use it on the job site daily and don't have the time to wash it daily. bottom line is that they should be able to take more abuse than they do but if you are going to get in an argument with the dealer its best to have it clean so it doesn't give them any way to try and weasel out of it and I think we all know that they will try. With it being 8 months old though I don't think you should have a problem getting them to fix it.

Another place that I noticed rust, and a lot of it, was on my hood right behind the top of my grill. When I bought my platinum grille and changed it with my old one, I noticed that the old one had rubbed all of the pain off where it was touching and was rusting. I'm a a lazy idiot though and still have done nothing about it. eventually it will creep up to a visible spot and I will be forced to take it to the body shop. I guarantee that I am not the only one who's hood is rusting behind the grille but you have to take the grille off to find out.

I should add that I think the look of the paint is amazing when it's clean and off the show room floor. The quality is garbage though. I'm no paint guy so maybe somebody else can chime in. would simply applying another coat of paint make it thicker and therefor less prone to damage and rust?
The dealer will cover it under warranty "IF" the paint has NOT been penetrated to cause the rusting. (If the rust developed under the paint)

If there is even a pinhole to allow water and salt to start the rusting then it won't be covered.
So like other have stated, it is unfortunate that it has happened.
But knowing that your area salts the road, you may want to take preventive measures to ensure that grit and salt doesn't penetrate the finish. No dealer will cover that type of rusting.

Also check your frame! It more then likely will be doing the same!

Good luck!
This does suck but I will say I have a 08 Chevy work truck and I have had a complete bare spot on my sill for at least three winters now and I have not a single sign of rust. I don't know why but rust seems to be a problem for Toyota.

Chevy trucks have a galvanized coating on the entire body except the roof. That's why they resist rust. I had a 2000 Silverado, guess where it was rusting?!:(

A lot of people notice tiny rust flakes on their paint over winter(more noticable on white). Its apparently from plow blades wearing, etc You might want to try clay barring your paint in case that's your issue.

I had the same issue with the grille at the bottom where it meets the hood. I put some foamy type tape between for now and got some touch up paint.
Thanks for the info guys. If this is what is considered a filthy truck then I am screwed, because if I need to worry about rust with this little dirt then i guess the truck will be garbage in 3 years. What I cannot understand is that there is probably upwards of a couple tens of thousands of these trucks in edmonton alone and probably hundreds of thousands (if not millions) in the same type of climate who either salts their roads or puts calcium down and I am the only one with this issue. In my opinion this is ,without a doubt, a shitty job with prep of the steel before the paint and the paint itself.

Thanks for that info I did not know that. I am by no means a Chevy fan anymore. I was a did hard Chevy guy until I started working in a fleet garage and worked on all the big 3 and Chevy was by far the worst when it came to reliability and we had about an even amount of fords and not quite as many dodges. It changed my mind completely.

keep us updated. I feel like rust there is REALLY not good. we're talking about a critical area of the cab. I would ask them to check ALL door jams if its UNDER the paint.

on a side note... my 2012 came with a step plate from the factory on that part of the door sill. Its just a rubber strip with adhesive on it, but still seems to protect it.
Well, stopped into the dealer this evening and it wasn't a big deal at all. He said that they have had a few trucks come back with the same problem and that they will send it out to a body shop, sand out the whole sill and repaint it. I said that if it is rusting on the sill can we assume that there is the same problem underneath? All he could say is that we cannot do anything about stuff we cannot see.

Anyways, has anyone tried coating the door sills with bed liner or had it done by anyone?
Have the dealer send it out to their body shop but make sure they warranty the paint job for life of the truck. My 2007 was horribly rusted beyond belief in about 14 months and 20K mileage. I even had a dime sized rust spot in the middle of the tailgate outside along with both rear rocker panels in the bottom rear corners of the DC doors rusted terribly no paint left about a 3-4" area just awful. My lug nuts were also rusted beyond belief and dealer knew the chroming process on both the front and rear bumpers along with lug nuts were inferiorly done from mfg. since several dozen had rust just sitting on their lot brand NEW no less.

It helps to go in calmly although fuming inside and also to have your truck washed and clean inside and out showing you take good care of your tundra, yes it does help. Anyways, no questions asked toyota dealer under 3/36K ordered an entire new unpainted tailgate, new front and rear chrome bumpers, and repainted the 3-4" spots behind and below the DC rear doors in the corners. They done excellent job at the dealers' body shop but the chrome lug nuts they did not stand behind since I think 5 lug nuts per tire x 4 x 10 bucks each was 200 bucks and dealer informed me they'd polish them but still had rust on all corner edges but barely noticeable. Dealer said they cannot justify brand new chromed lug nuts since they have done that in the past and 6 months later the new lug nuts are already rusting no fricking joke they told me that.

I thought the rust issues were solved in either 2009 or 2010, guess not, but the 2007's were terrible and 2008's as well being rust buckets in both paint quality and chromed items. Plus, in my opinion, the rusted frames in 2007 like mine were 5x worse than my 2010 or 2012 similar mileage.

Rust under the sill... Don't know about you, but I plan to pop out the plastic grommets for the running boards and spray rust inhibitor in there. I think that will stop any rust already there, and (hopefully) prevent it from the first place.

Inside my rear bumper is pretty badly rusted. The skid plate under the engine wasn't. Everything else was great, not bad for being in salty NH. Not sure how it bods for the future, but am hoping for the best.

Good that your dealer is fixing this for you! There are tons of Tundras in Alberta and this isn't a common problem, so something was obviously off with your truck.

The 3M paint protection film works really good on the door sills. Even my 7 year old climbing in and out hasn't worn it at all.

Trucks these days are shit, from the paint, to the body panels to the VSC problems. I can't see keeping mine for as long as my Taco.

BTW, my GODDAM seat knock is starting to piss me off. I feel like I'm getting kicked at each stoplight. (yes, I'm 100% sure its the seat)

Yeah no I wouldn't really call that interior filthy at this point yet... plus you actually have floor mats.
