Toyots Shafts thosuands of used auto buyers
 I purchase this 2007 Tundra approximately 1 year ago. The truck was in very good condition, seemed to run well, and only had 43000 miles on it. I believed that I would have several years of relatively maintenance free driving. At about the 14 month  period all of the idiot lights came on several of which start flashing, and the truck went into ( What I now know ) is considered  "Limp Mode" This is where the computer only allows the vehicle to go so fast in an effort to protect the engine of damage. I drove the truck to the Toyota dealer, where the mechanic indicated that there were four components of an air-pump system ( Part of the emissions control system), two of which had failed.  He indicated that Toyota new the components were junk and had extended the warranty for 10 years or  150000 miles. This would probably be a saving grace for most owners who owned vehicles that had been driven enough miles for the parts to fail; however those that had not, or those that have recently purchased a  low mileage, 2007, are out of luck. Repair cost to date just shy of 2300.00 Do not buy a Toyots vehicle between the years of 2007, and 2011 regardless of how cheap it is being sold.
