On two different occasions I was driving my tundra on the freeway at approx. 70 MPH. My truck lost power and I almost caused accidents on both instances since I could not accelerate past 40 MPH. I had to manage my way out of the freeway to a safe place. 2two diagnostics were performed and I received codes p0418, p1604, c1241, p2445, p2441. I was told by the toyota dealership that there was a problem with a faulty secondary air injection system pump and other components related to the system and I was provided a repair cost of over $3,000 dollars. I was later informed, and I discovered through research, that toyota had installed faulty/defective air pumps in thousands of tundras 2013's like the one that I own. I reached out to corporate office but they stated that my VIN number somehow did not "qualify" as one of the affected pickups. My tundra only has 60k miles and I use it to commute from and to work basically. I perform routine maintenance. There is obviously a problem with a defective secondary air pump system that toyota refuses to fix. My truck is a liability on the road and this is my only means of transportation. It looses power and the check engine light activates. Toyota recalled thousands of vehicles like mine and fixed them after they acknowledged that they had placed faulty air pump systems. My truck is a potential possible cause for an accident since it unpredictably looses power on the freeway. I have not received a solution from headquarters/corporate office to repair my truck at no price since it is affected by their faulty pumps. They did offer $750 dollars towards the cost of parts, meaning that I have to come out with over $2000k out of pocket. I need toyota to take responsibility and fix my truck.

My 2013 toyota tundra truck ( 74,734 miles) suddenly had engine failure while driving down an incline at 48 MPH. I lost power steering and power brakes. After eventually pulling the wheel with much effort and using the emergency brake I was able to get the truck off to the side of the road. I turned the key and the engine started right away and I was able to drive again but only at a reduced speed of 40 MPH or less ( it's called "limp" mode) my mechanic diagnosed it as a secondary air injection pump failure. Upon investigating this on several tundra owner message boards, I find that this is a common failure tundra trucks at around 75000 miles. The toyota dealer confirmed that this has been a common problem and looked up my VIN number to see if it qualified for a warranty extension program that toyota has offered for some 2012 and 2013 tundra trucks. Unfortunately my VIN number was a few numbers beyond the extension program. Had my wife been driving the truck when this happened, I am not so sure she would have had the strength to safely bring the truck under control and get it off the road with no power steering or power brakes. I want toyota to extend the warranty on this faulty part before someone gets into a serious accident. They have obviously admitted there is a problem with this part and should extend it to all toyota truck owners with this particular problem. Not just a select few.

Ecu problem. Since june 2018, I have started to see decreased mpg (avg 9 mpg, 50/50) and vehicle exhibiting high alc. Density % when fueled with e0/e10 gas. No dtc codes, but extended crank exhibited, poor performance and shifting observed. This is a flex vehicle. Fuel trims were way into negative and I have called toyota and filed a case when this happened, but was out of warranty by 2 months.(called aug 2018) vehicle had 55k miles. They said its up to the dealership to remedy the issue. Took it to the dealer and they re calibrated the ecu per toyota tsb 0058-13 (so they know of the problem , but not doing anything about it) to me it looks like they are hiding something, (dieselgate) for a year, vehicle was fine and did not show any issues with alc. Density % , mpg was normal and performance/driveability improved, until sep 2019. Same thing. Alc. Density % too high causing poor mpg. I have to pay the dealer too just reset the values, even though this issue falls under federal emission standards and it has warranty of 84 months or 80k. So even after the fix ecu changes the values after a year. Clearly ecu issue that toyota does not want to take responsibility for. This goes against gas emissions (ghg) and fuel economy standards for light-duty vehicles. There are known issues about this out there on flex fuel tundras, but toyota is trying to hide this.

Truck stopped excellerating. Took to mechanic and was told it was in safe mode due to the air injection values had water in them. It will cost $2336.00 to fix it. This should be recalled.

The air injection pump is defective and allows condensation and or moisture which leads to totally failure. I have already spent 1100.00 dollars for one side now the otherside is failing..this failure caused the truck to lack any get up when pulling out into traffic. It wants to stall.

I was driving and out of nowhere my engine light comes on. I take it to auto zone to do a quick check and I was informed that it is my injection pumps that are bad. I did research and in the past toyota has had to recall for this exact problem on the exact vehicle but it was for a different year. I called toyota and they said my vehicle year does not fall into the recall but I'm sure that it is the exact thing.

Developing high alc. Density % when using only e0-e10 gas. Tsb 005813 was done in 2014 , but issue resurfaced. Toyota unwilling to fix the problem. Dealership want to charge for the fuel pump. ($1500). 5 year warranty ended june 10 2018. Truck has 54k miles. Toyota knows of this problem and it is a fuel pump. Truck has poor mpg due to this and lacks power. Ecu thinks truck is using %40 ethanol which turns high pressure regulator in the pump itself and tells ecu to pump more fuel. Toyota nor dealer wants to reflash the ecu. Tsb falls under federal emission warranty 96 months or 80k miles.

Toyota dealer and toyota technical support are unable to fix the problem associated with t-sb-0058-13. This is the second time within 3 months or so that I have taken my 2013 toyota tundra in for this fix. Fuel economy drops on average of 30-40%. Toyota refuse to acknowledge that this is an issue, and is refusing to cover costs associated with fixing this recurring problem. This has been stated as a software gliche, and there are no parts to replace. Hard starts, rough idle, and reduction in fuel economy can only be fixed by reprogramming the ECM. Dealership is saying there is nothing that toyota is willing to do. This issue is impacting thousands of owners, and the only resolution toyota has is to flash the ECM. If this is a software issue I would expect that toyota issue a recall to address this problem since it has been ongoing for multiple years of this engine combination. They know it's a problem, but are not doing anything to address it. I have logged multiple calls in to toyota for this problem, but have received no follow up contacts.
