I received a check engine light for the secondary injection system. Toyota extended the warranty but wont honor issues after 10 years, even though the truck has less than 100K miles. This is a safety issue as the trucks performance is altered and concerned about passing a car on a two lane highway. The repair can range from $2K to $4K pending on the dealer.

Engine leaking oil while running at the cam towers on both sides causes oil to drip onto engine exhaust header. This unsafe condition could cause a fire. This condition happens to all 4.6 and 5.7 Tundra and sequoia engines produced after 2007. This is an extremely expensive to repair. The manufacture made these engines with inferior sealant at the cam towers.

I was driving normally down the road after work and the vehicle started running rough and wouldn't go over 40 mph. I took it to autozone and called the Toyota dealer in morristown, tn. They told me there was a recall on a oxygen pump up to 150,000 miles on my vehicle and that because my vehicle was over 150, ooo miles that it wouldn't be covered and it cost over 2,000 to fix it. I wrote a letter to Toyota and they said they couldn't cover it because it was my fault I didn't check for recalls when I bought it used. They never sent me a recall letter on this at all, I had bought it at around 126,000 miles and received no recall letters when it would of been covered. This is my complaint that maybe you can help me. I can not afford to fix something like this. I should of been notified. They said it was my fault I didn't check for recalls not their problem.

The contact owns a 2010 Toyota Tundra. While driving approximately 65 mph, the check engine warning indicator illuminated and the vehicle lost acceleration power. The contact pulled over to the side of the road to a complete stop. The vehicle was turned off. The contact restarted the vehicle normally, but the acceleration power was lost and the warning indicator was still illuminated. The vehicle was taken to the dealer where it was diagnosed as air injection pump failure. The contact was also advised that the manufacturer issued an extended warranty for the failure, but the vehicle was over the mileage. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 180,000.

My Tundra has 48048 miles on it. I took my Tundra in for an oil change and was told there was a oil leak in the cam tower. The cost to fix it was $2850. It was no longer under warranty. I did a little searching and found that this is a problem that has occurred frequently in this engine. I contacted Toyota and was told, after they consulted with the dealer, that the problem wasn't a defect, but caused by engine wear and altitude. They offered to pay for parts, which were $420. If it is really engine wear, I expect this to happen again. In talking to the dealer, I was told this is a one time fix, and it should not happen again. Something isn't right here. Either it is a defect in the engine and this repair will fix it. Or it is normal wear and this will keep happening. I feel this is a problem that Toyota should fix, since it seems to be happening frequently. Many people reported it happening while it was under warranty. Mine just happened to have occurred after the warranty expired. Either way, it is not acceptable to have this happening in this engine with low mileage. Apparently the oil leaks down from the engine onto the exhaust part of the vehicle and can cause fires. It also can leak out and cause engine damage if the oil gets too low. I hope you can help me.

I bought my 2010 Toyota Tundra brand new in Feb. 2010, during a routine oil change at Toyota dealer recently, engine oil leaking was noticed by the technician. The repair was done to reseal both cam box housings and replaced seals and gaskets that are related. It costed over $1800. Unfortunately, the vehicle just passed the powertrain warranty, since it has been 5 year and 11 months, but the mileage is at 38,000, related low. I have contaced Toyota us headquarter, told them the oil leaking most likely started before 5 years mark, but it was just discovered now. They refused to reimburse the repair cost. The dealer service technician told me that he has seen many Tundra had this oil leak issue, and most of them were within warranty, so there is no recall for this issue so far, I also did research on internet, found other people had this oil leak issue for their 2010 Tundra and 2011 Tundra. I would like NHTSA to investigate this wide spread issue and hopefully let Toyota do a recall for this defect!

I was on the highway when the engine stalled, and I barely managed to get my truck to the Toyota of dallas dealership, where I had bought my vehicle. They found that between the valve block and valve there was a ring that had come loose that caused the engine to stall. When the car began to stall I could not control the steering and the brake stopped functioning properly. I am a safe driver and had maintained a safe distance between my car and those in front of me at all times, but the situation I was in was very hazardous because when the engine began to stall it made it very hard for me to manage my vehicle. Because I felt that there was no particular reason for the valves to be damaged, I did some research on the engine myself and found that the Toyota V8 4.6 liter engine is also in the Lexus LS460 and RX460. The engine has already been recalled by Lexus because of issues with loose springs, so I think the sudden damage to my engine may have been caused by the same reason. Is there a possibility that the engine is defective?

Vehicle was traveling in freeway and all of a sudden the A/T oil temp light came on and the vehicle stop right away. Engine and everything stop working. I think this is serious and too dangerous. Hope someone will investigate the issue.

In slow moving traffic, repetitive light gas and light braking. Noticed the brake becoming difficult to depress. Had my left foot stationary on the foot pad, right foot over the brake while rolling forward. Started to drop my right foot on brake as vehicle slowed in front of me and engine suddenly accelerated rapidly as if to full throttle. Pressed on the brake as hard as I could, engine redlined and rear tires started spinning. Popped it in neutral and within a second the engine stopped accelerating out of control. Floor mats were not interfering with any pedals on my immediate inspection after incident. Incident caught on dash/windshield camera.
