The frame of the truck was recalled for excessive rust. The dealer sprayed on a coating per the recall in 2013. The coating has all flaked off and the frame is losing chunks of rust. Toyota know about this problem but won't do anything about it once they spray the defective coating on it. The truck frame needs replaced and they won't do it. Somebody is going to be seriously injured or killed in one of these trucks when the frame breaks at speed.

Cold start of vehicle, very large noise, lasted about 1 minute. Only does this when cold start. If vehicle has been driven no sound. Research indicate, that other problems noted on the internet were the air injection pump, and switching values, has foam that has deteriorated and fell down on the DC motor and burned the motor out. Seems the manufacture knows of the problem but has only certain model years they are covering. Same part in all years but not covering 2005 which is the model year of my truck. If same part is on different model years they should cover all model years that have this part as it seems this is a very expensive repair. This is a requirement to utilized to improve cold-start emissions, which is mandated requirement. Toyota's customers have a customer support program to extend the warranty should be with all model years that have this part. I have as of yesterday taken my truck to the dealership as I am pretty sure this is the problem. Diagnosis should be forth coming. Many complaints on internet for this same model year and problem.

I just sent the following email to Toyota. I hope that NHTSA can follow up as this is very concerning: I was horrified by the spanish speaking Toyota Tundra commercial I just saw. It is inconceivable that Toyota would have a commercial showing little children crawling under a car to try to get a ball out from under it. Children shlould never go under a car, whether it is moving or not. They can't tell the difference! this is absolutely shameful. Toyota should immediately pull this commercial. Please do not be responsible for the death or serious injury of a child or children who crawl under a car after seeing this commercial.
