While driving down the interstate the check engine light and traction control light came on and the vehicle loss engine power and began to slow. After I could not accelerate and it became unsafe for me to drive without the possibility of an accident occurring and possible injury or death, I pulled over and had to limp vehicle back home. Toyota refuses to fix it saying it only offers replacement on the 2007-2010 toyota vehicles. The defective part number is the same on my 2011 as all the other toyotas but they stopped covering it in the later models. The dealer said they had to repair so many that at one time there was a 60 day backlog on parts. This is ridiculus and toyota is risking the lives of those that drive their product. I will have to pay to fix this on top of what I paid for the vehicle. I will warn everyone I can reach to never buy a toyota. Toyota has become a company of subpar customer support and deserves every class action suit they get filed against them. Whoever begins one on these failed air injection pumps count me in for the refund and the mental anguish of trying to get toyota to stand behind their product!!! This could have cost me my life!!! Unsafe!!!

On sun. 10/11/14, I drove our tundra on the highway when it lost power. The engine raced and rpms increased, but the speed fell and no acceleration was possible. On a hill, speed fell to about 15 MPH. I was on my way to pick up my horse and trailer; if I had been towing them, it would have been catastrophic especially given the highway speed traffic. It was still dangerous even without the trailer. I turned on my hazard lights and limped off. "check engine" lit up. Took to dealership the next day, who said check engine code was "p2445" for "secondary air injection system water intrusion" requiring replacement of the air pump assembly, air pump inlet, emission valve set, etc. For $2600 because water invaded the system. The service tech said that this was not a known issue, but my internet search showed that toyota issued a 12-page 2011 technical service bulletin, stating that "the air pump assembly inlet has been updated to prevent water intrusion." toyota has neither recalled the defective inlets nor notified owners. The tsb says only trucks under the 36,000/ 3 year warranty are covered. Tundras are tow vehicles and it is foreseeable how unsafe this is. Because my truck was sold just over 3 years ago, the local dealership at first could not cover it. I contacted toyota headquarters, who referred me back to the local service manager, who then reached southeast regional toyota office, which finally agreed to cover the repair. When this air pump inlet fails, it allows water to enter the air injection system and the system to then fail in the dangerous way that occurred in my case, resulting in a sudden loss of power. I am concerned about this happening to others and that the dealers seem unaware of this tsb and this "known issue." tsb link is here: http://www.autosafety.org/sites/default/files/imce_staff_uploads/t-sb-0160-11.pdf.

Truck's computer is reading an incorrect perceived alcohol density. Truck has a flex fuel engine and the computer is telling the engine that there is ethanol in the fuel system while there is not. I have never run ethanol in the truck yet the computer is reading that there is a 30-50% alcohol density in the fuel. The problems that have resulted from this are missing while under power and power loss while driving. Have had my truck to multiple dealers over 5 times now. The dealers have continued to re-flash my truck's ecu only to have the problem to come back because the ecu is a learning ecu. Toyota has released a fix for 2012 and 2013 models but not for the 2011 models which is leaving me stranded. I pull a boat frequently and the loss in power has significant negative effects on towing. This problem also causes the engine to run lean resulting in poorer fuel mileage and increased costs for me. I've talked with people at toyota corporate and they have told me that there are no plans to release a fix for the 2011's and that there is basically nothing that I can do. So now I'm stuck with a truck that is reading the fuel wrong and causing the truck to run lean which is surely gradually damaging the engine which I'm sure will result in lots of repairs after the truck is out of warranty.
