Air injection relay and pump failure. This has been an extended warranty item on all trucks except the model i have with the same parts as the larger engine truck. This is a corporate game of not enough complaints on a less popular model engine even though the parts are the same as what is being replaced on same year models with the larger engine. Repair is estimated at $2600

Air injection relay and pump failure. This condition eventually leads to "limp" mode causing traffic safety issues. This has been a manufacturer recall/extended warranty item on all tundra trucks, up to and including some 2012 models but not all of the 2012's. By the numbers of failures present, it's obvious that what ever design changes toyota did to say they fixed the issue and exclude some of the 2012's were…

My 4x4 toyota tundra crewmax with the 5.7l engine was diagnosed with a cam tower leak with only 15,000 miles on it. Fortunately the vehicle was still under the factory power train warranty. Toyota made the repair and provided a rental car for me. I have heard this is a common problem with the 2012-2013 5.7l engine and i want this issue to be more public. I worry owners of this vehicle will be stuck with the…

Flex fuel models sold by gulf states toyota have an issue where the engine's computer thinks there is e85 fuel (or an alcohol concentration that is much higher than actual) in the system when there is normal 10% or less gasoline actually present. This can cause rough cold starts/idle, power loss, sudden rpm/power dropout, missing, and lessened fuel economy, etc. (different symptoms for different trucks). At this…

On 12/24/2012 around 04:00hrs i struck an adult moose in bear lake, canada with the front end of my wife's 2012 toyota tundra crewmax on the british columbia highway. The condition of the road was snow and ice but we had recently purchased aftermarket rims and tires on 12/18/2012 in california; 18in mb votex rims with bfg all terrain tires. The traction of these tires boosted my confidence in traveling at speeds of…

I had an extended crank time, and it would take multiple attempts to start the truck. I took it to the dealership for the first time in january of 2013. The dealership reset my computer. The issue seems to be resolved. The following winter, in december of 2013, i started to experience the…
