My Tundra with 75,000 miles has a camshaft tower leak and this oil is falling into the exhaust manifold without being noticed because it doesn't make it to the floor, but it gets to the sensors and starts ruining them. Toyota motor CO knows about this issue in all their 5. 7l engines and that its a factory robot error by not applying enough sealant in the gasket. And this is just being fixed if you are either under factory warranty or extended warranty. The vehicles loose power and if driving on a highway can cause a major accident. The least this company can do is offer a voluntary recall but they are refusing to do so because the fix will cost them $3500-$4000 from all their 5. 7l engines assembled in the u. S. So for my safety and the safety of many Toyota drivers and general highway drivers safety, I hope this would be taken into consideration. Thank you.

Truck was in Toyota shop in vermont for stalling of vehicle. Thought it was fuel pump due to recent recall - specifically asked if it could be that and was told no. They found mice nest in intake manifold, knock sensor was found to be chewed, and replaced. Once I received my vehicle, it continued to do the same thing after 2 days. Upon looking under the hood, found that the air intake filter was left off. I fixed that, and then the same issue starting occurring again. Had to have my vehicle towed to different shop (to trusted mechanic) they have found after replacing the battery and a mass air flow sensor, that it is truly in fact the fuel pump. They tested fuel pump and it's only putting out 20psi instead of 40. I called Toyota, but they are claiming that only the newer Toyotas are affected, but on the recall list it goes back to 2013 in different models. This seems similar to the issue Subaru was having with their air bags. My Toyota dealership, should not just be assuming that this couldn't be correlated with faulty fuel pump. My vehicles symptoms are the same as what the recall has stated happens. Before denying me anything, they should be willing to at least investigate and look at my vehicle. It's also suspicious to me that my vehicle started doing this about 2 weeks prior to a huge safety recall coming out in regards to fuel pumps.

I have noticed an oil leak from the camshaft housing on my passenger side. This has led to oil burning on my exhaust manifold which is a fire hazard.

Cam tower oil leaks on both driver and passenger side - oil leaking onto to manifold causing smoke - possible fire risk - numerous complaints went unanswered, finally diagnosed by the dealer, however Toyota not willing to fix as vehicle is outside of manufacturer's warranty - this is a known issue!!.

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 $2,300-$3,000 bill to fix their own vehicle if their vehicle's power train warranty has expired. I also worry the engines could leak oil onto the exhaust manifold and catch fire.

The Toyota safety recall work done in 2012 to treated my vehicles frame to prevent rust perforation has failed. During nh state inspection areas where the frame had rusted through were identified. These areas had been treated under Toyota's guidance and at their expense. Due to frame rust perforation, and rust issues identified below my vehicle would not pass inspection. Toyota of portsmouth, where the initial recall work was initiated, and Toyota motor sales have both denied to remedy this situation. Many other 2001 Toyota Tundra owners were provided complete frame replacements. I was provided with a rust treatment that has failed to correct this safety issue. The state inspection was requested by me prior to spending $2,776 (and up to $5,000 or more if internal parts were damaged) to replace a rusted through and leaking rear differential case that could have seized up at highway speeds if I had not noticed the leak. This inspection also identified for the second time a rusted through and leaking exhaust manifolds (the left manifold was "starting" to leak on 09/16/2014 when the truck last passed inspection. I heard the ticking sound, characteristic of this leak, since the vehicle was under warranty and told it was normal. The body and bed of my truck was determined by a local body shop to be in good condition with minimal rust. This was determined by visual inspection and the condition of the lower portions of the doors which are frequently a trouble spot in states where road salt is used and the first locations where rust (body rot) appears. Toyota has failed to provide adequate corrosion protection on the frame and rear differential of my truck and created serious safety issues. The frame rust treatment Toyota used on my truck did not work. I do not understand why they have declined to remedy this situation. They have replaced many frames for others.

Continuous oil leak from cam tower onto exhaust manifold. Dealer denied the issue even though the signs are very obvious. A call to Toyota to got me no where. They denied the issue like the dealer. There is oil on the engine block and also the exhaust manifold is black from the all of the oil dripping. After driving for awhile the car smells like it's burning. There is a very real potential for fire. The issue appears to be widespread. A quick internet search can find extensive examples. Toyota appears to be reverting to it's old ways and not taking responsibility for serious safety issues.

My 2008 Tundra suddenly showed multiple dash lights when I started it. It ran rough, tried code reader on it ,again multiple codes at once. Every item can't bad all at same time. The main problem was air pump failure, have a feeling it's associated with exhaust problem. Truck has been ticking since about a month after I bought it brand new, I just assumed that's the way it was since it quiets after warms up. Turns out manifold is cracked by the pump. Of course warranty is up. After reading online seems like a lot of people are having same problem. Have had it several times over the years for oil changes etc. . The dealership's know there is a problem and ignore them. I have two other Toyota cars and this is the first Toyota truck I've bought . Toyota we'll have a bigger problem when go back to buying the chevy,Ford, Dodge. They were buying before they came out with full size Tundra. Get your act together Toyota or you will lose a lot more money and respect than what the recall will cost.

2005 Toyota Tundra. Consumer writes in regards to air induction pump design flaws the consumer stated according to the mechanic's report, the second air pump, secondary air switching valve, bank 1 and bank were replaced. They were all clogged with insulation foam and stuck to the valve seats which kept the valves open. The secondary air inlet was also replaced, due to the hose being hard because of the heat under the intake manifold, which also contributed to the engine not being able to cool properly. Further research about air induction pump design flaws on Toyota vehicle revealed a nationwide problem affecting Tundra's up until the 2010 model.

The engine check light came on and the engine went into limp mode, which reduces engine power making it dangerous to drive. The check engine light came on from the emissions valve set failing. When repaired by dealer they also discovered a cracked manifold. This emissions valve set failure seems to be very common on 2008 Tundras and is very expensive to repair. To my surprise the manifold was cracked and that is a very expensive repair and may have contributed to the emissions valve set failure. Toyota should recall their emissions valve set and redesign it so it does not fail, and is less expensive to replace, and finally they should not program the engine to go into limp mode if this failure occurs, as it can cause you to lose power while driving in various conditions that require power to get off the road safely.

Toyota Tundra 2007 w/ 4wd. Vehicle went from normal 2 wheel drive into 4 wheel drive low without warning, without touching any controls.

Exhaust manifold crack.

Exhaust manifold failure; cracks in the exhaust manifold causing forced exhaust emissions into the engine compartment which will eventually cause carbon emissions coating the interior of the engine compartment and thus can potentially cause fire in the engine compartment which can result in death; also exhaust fumes can make their way into the cabin of the vehicle and thus cause the driver to lose consciousness and result in accidents and potential death. This is the 3rd failure so far.

Continual problem with exhaust manifold leak, drivers side, possibly resulting in oxygen sensor failure. Continual problem with brakes. Dealer claims it would cost between $1,800 and $2,000 for manifold repairs. Private shop wants $650 just for one manifold.

Exhaust manifold are cracked. This is a very well know issue with these manifolds and Toyota has not stepped up and taken ownership of this problem. Exhaust gases leak into the engine compartment which could enter the passenger compartment and create a serious risk to health.

"ticking" sound from left rear of engine block. I know it was an exhaust leak. Went to Toyota dealer and they said my exhaust header was cracked and rusted. The truck was bought new in texas. According to the service manager named gabe at camelback Toyota in phoenix, az, "the humidity in dallas must have caused the rusting. " the truck has 79,000 miles on it with no rust anywhere else on the vehicle. When I inquired to the price of repairs, he said $1800. However, he added, I could get the "improved" manifold, "which has thicker welds, for only ten dollars more. " this seemed every odd to me that Toyota already has an improved design for the header that rusts from the "high humidity" of texas.

2001 Toyota Tundra 32,500 miles, both exhaust manifolds are cracked, the dealer states that the car is out of warr. After a month of back and forth with toy. Main office. They tell me they will pay labor and 1/2 part,I pay the rest ($350). This is a design problem exhaust manifolds don't crack, this problem is the fist line in the msn review of this car & all over the web. What does it take to get "satisfaction & reliability" from Toyota just admit there's a design problem and fix it. .

Premature exhaust manifold failure, causing exhaust gasses in engine compartment and possibity of entering passenger cabin. This would eventually result in drivability problems. Internet search uncovered large amount of similar premature failures and affects to reliability ratings.

Vehicle was experiencing an exhaust manifold leak. Consumer took vehicle to the dealer, where consumer was informed that there were cracks in the exhaust manifold.

The contact owns a 2002 Toyota Tundra. In 2004 the contact replaced the oxygen sensors, and the vehicle was at the dealer for the same repair. The failure occurred less than 20,000 miles apart from one another. He discovered a technical service bulletin with item # 10007090 ( concerning engine and engine cooling:exhaust system:manifold/header/muffler/tail pipe. The contact stated that other vehicle owners had the same failure, and felt that the manufacturer placed a defective component on the vehicles. The contact and the other vehicle owners should not be required to pay for the repairs. The current mileage is 53,000, and failure mileage was approximately 30,000.

My 2000 Toyota Tundra has developed a crack in the exhaust manifold. This is not a normal defect so I did some research. Apparently, there is a TSB for the O2 sensors and then sometimes in changing these the dealership also has to replace the manifold because the threads strip. Maybe Toyota is just trying to hide the problem with the manifold. This is a common problem with Tundra's and I feel that there should also be a TSB on the manifold. This type of defect is not normal on vehicles of any age and it is very widespread among the Tundras.

I have been informed by my Toyota repair facility that my 2000 Tundra is in need of new exhaust manifolds. The truck currently has 54,000 miles on it. The repair will cost $1900. 00 it is my understanding that the manifolds on these trucks are failing at a greater rate than Toyota will admit to. A vehicle with 54,000 miles should not need the exhaust manifolds replaced. Toyota needs to address this problem, and correct the faulty parts, without charge to the customer.

2000 Toyota Tundra exhaust manifolds leaking. July 3. 2003 a Toyota dealer told me my exhaust manifolds were warped and leaking. Mileage at that time was 30763.

I feel that Toyota should cover all costs.

Cracked manifold, will be replaced with an identical part which is very likely to also crack and I will have to pay for repair. A manifold should not crack at 60k miles!.

I had smellled fumes in the cab and began to hear what sounded like valve tapping noises at start-up. After several weeks, I took the vehicle to Toyota for inspection.
