 I purchased my brand new Toyota Tundra SR5 double cab 4.6L in 2012 from a local dealership. Two weeks ago my check engine and TRC OFF lights came on so I rushed to a nearby Toyota dealership an hour later the service tech approached me to explain that my secondary air injection valves were closed reason why my truck would only get up to 40mph and felt bogged down. He then informed me it could be a matter of resetting the computer and the valves could reset themselves and I will just be out $100.00 for the computer testing. Or my air injection valve assembly could be bad. Another hour later he returns to tell me resetting the computer did not work and I would need to replace the air injection valves if I got it repaired there and right away it would be $2,500.00 if not $2,800.00. Between all of this fiasco they are trying to sell me a  new truck I need to mention. So after me asking a million questions he then says its nothing I did NO NEGLECT on my part to my truck it's a manufacturer issue but unfortunately my truck is not covered under the recall/warranty. The recall/warranty is only on the 5.7L Tundras so after lots of research I have found Toyota has had many issues with this valve system since early 2000.I went to the dealership where I bought the truck and was told unfortunately I just have really bad luck and I could be 1 out of 10,000 people this happens to then of course they kept me their trying to sell me a new truck. I do need to mention my truck is still at the dealership that diagnosed my truck originally. Then I'm told we can not help you at dealership level you have to call corporate. I call corporate and they made a case but then of course pointed the finger at the dealership. Bottom line Toyota YOU bought a faulty manufactured part YOU need to take ownership of it, it is not my fault your vehicles have rust issues, break issues, airbag issues and air injection valve issues. I have never been so rudely mistreated like this by a company that supposedly has great customer service...NOT TRUE at all. They care about one thing and one thing only their bottom line and profit. This was the first Toyota I have ever owned and needless to say it will be my last. My truck had 130k miles on it and I owe 5k on it, now I have to put 3k into it....BS!
