Manifold/header/muffler/tail Pipe Problems of Toyota Sequoia

Toyota has developed what is becoming an infamous oil leak on their 5. 7 v8 engines that is coming from the camshaft tower (camshaft housing sub assembly). Apparently in production they use a silicone where this attaches to the head and in many cases they did not get enough silicone. Research has shown me that many, many of these have this issue and that when the vehicle is fairly new that Toyota will stand behind it in limited cases. My vehicle has 150,000 miles on it so they will not do anything to stand behind it and claimed to not be aware of the problem. I have contacted several dealerships and all of them stated they were well aware of the problem. I believe this to be a safety issue as mine has started to leak, it does so on to the exhaust manifold and has a strong burning smell each time I drive even if only a short distance. This could easily cause a fire. While I am not aware of any of these causing a fire it is a very common issue to the point that I found a law firm that was looking to do a class action lawsuit because of it. I can provide pictures if needed but they can be seen all over the internet.

My 2013 Toyota Sequoia with the 5. 7 liter engine (only 28,000 miles) is leaking oil by the cam tower (left side). The oil is landing on the manifold which can catch on fire if not repair. Not a safe SUV to drive on long trips.

Brought in car to have muffler checked out and my mechanic called me back after putting car on the lift. There were rust perforations the size of a football as well as openings along the whole frame. The mechanic told me it was unsafe to drive and that this was not normal wear for this vehicle. He was concerned that the drive train would fall through if we went over a big enough bump and cause an accident. The rust was abnormal and he said that it looked like it was rusting from the inside out of the frame. I called Toyota to file a claim and they had me bring it to the local Toyota dealer. They refused to send out a regional rep to look at it saying it was not under a recall of any kind. Now my car is unsafe and worthless. The Toyota corp. Customer service told me to sell it for parts. . . . Really??? they did nothing and offered no answers. Please research this problem and get something done about it. Does someone have to die to get the attention? you buy a Toyota for its longevity and quality. I will never buy a Toyota again.

My Toyota Sequoia 2011 has a slow leak at the front passenger side just on top of the exhaust manifold,took it to the dealer and they said the cam shaft oil seal is leaking. They are willing to fix it,but my concern is if my car will be the same again since its just 6 weeks old,and I might encounter more problem in the future considering they took the engine apart.

Discovered rear bumper was severely burned around tail pipe after pulling a trailer. I purchased the vehicle new from modesto Toyota. I brought the vehicle to modesto Toyota and reported the problem as a factory defect. They inspected the problem and reported back to me that there was nothing wrong with the tail pipe and because it was beyond the warranty period there was nothing they would. I have looked at another 2010 Sequoia which pulls a travel trailer and discovered the same problem. I feel this problem has a potential to start a fire and should be covered by Toyota regardless of vehicle miles.

Engine oil seepage (or slow leak) at the cam housing and engine head connection (gasket seam) area, above the exhaust manifold, on the right-hand-side engine cylinder bank. Oil first detected at 9,000 miles (vehicle was purchased new). Concern: possible engine fire if the oil seepage becomes worse over the course of additional miles driven. Oil seepage should not occur in an engine this new - especially in areas near a hot exhaust manifold. Other similar Toyota v8 engines appear clean at the same area - no oil residue apparent in other Toyota v8 5. 7l engines of similar specifications. This appears to be a material surface manufacturing defect in my vehicle's engine. Engine info: Toyota 5. 7l v8 corrective action: I took the vehicle to Toyota dealer to repair the seepage or leak to avoid a possible engine fire (as a preventive measure), and dealer told me I had to call Toyota. I called the Toyota customer experience center 1-800 number and the recording stated I was not able to speak to a Toyota representative and I should call back later. I have not been happy with Toyota's customer service. When I asked a service manager at a dealer about getting this repair done under warranty, he responded by saying "I can't do that to Toyota. " it is unfortunate that Toyota values itself more than it values customers.

After 4,399 mi. The left exhaust manifold cracked and produced a ticking sound on acceleration and exhaust fumes can be smelled through the vents when fan is on. As per dealers advice, it's ok to use vehicle pending repair. It's been 5 days and the part hasn't arrived yet. Contacted dealer few times to facilitate repair.

Both exhaust manifolds had to be replaced as they had developed leaks.

We have a Toyota Sequoia, the problems are the 4 wheel drive is not operating all the time. It does not engage sometimes and does not stay in 4 wheel drive. One example is my wife had six friends in the vehicle the 4 wheel drive did not stay engaged and the vehicle skid control made the engine loose power so she slid backwards down a hill. No one would ride in our 4wheel drive again. The vehicle skid control makes the engine loose power while in traffic. There is also a hesitation in the engine when accelerating from a complete stop. Another problem is the braking system is not adequate for the vehicle. The entire front brakes had to be replaced. The vehicle has been in for the same repairs at least 10 times and is still not working the way it should. We have all the documentation for service on our Sequoia. We have done internet research through NHTSA and have found the same problem with other Toyota Sequoia's. There was also a problem with the air conditioner having a bad oder from bacteria growing, the exhaust manifold was loose and the power window motors made a loud noise. We have filed a complaint on all the same problems with NHTSA, comsumer affairs of California and you. We want to pursue the lemon law and get our money back. We are currently working with Toyota arbritration but are getting nowhere. We have had Toyota's previously and had no problems with them. This vehicle is a lemon.

After meeting with district parts and service operations manager steve carlson on 9/23/02. Iã‚ve come to the conclusion that Toyota will not fix the problem I have with the smell coming from my 2001 Sequoia. First of all, I had to call the dealership at 10:30 in morning to make sure that the manager was going to be there. Second is that I got the run around about I should try a ã‚for fun and gigglesã‚ by not running my recycling mode when driving with the a/c on. Third is that when the front windows are open iã‚m still getting the worst smell of exhaust coming from the rear. I understand his point about the balance of air with opening and closing of baffles in the rear and front of the vehicle. I want to make a note that the venting of this vehicle without the recycling on is the worst iã‚ve had in all the vehicles iã‚ve owned. The idea of asking me to use the front vents instead of recycling is a catch 22. Where if I keep the recycling on and smell the exhaust smell with itã‚s 0% emissions in my vehicle compared to opening the front vent and smelling the car in front of me with who knows what. Fourth, I have to get enough people to complain about this problem before Toyota will do anything to fix this design fault.

The contact owns a 2001 Toyota Sequoia. While driving approximately 5 mph the contact heard a ticking noise in the engine. The contact stated that the failure had been on going since 2002 and it occurred daily. The vehicle was taken to an authorized dealer who advised her that it was just a noisy lifter and nothing to be concerned about;however, the failure continued to occur. The vehicle was taken to several dealers and mechanics who were unable to diagnose the failure. During state inspection she was advised that the manifold casket was warped and that carbon monoxide was entering the vehicle. The vehicle was taken to an authorized dealer again who stated that the manifold casket needed to be replaced for $2,300. The vehicle was not repaired. The approximate failure mileage was 25,000. The approximate current mileage was 100,000.

Bought November 4th 2000. New tires at 20000. Smelled exahust when vents are in recylce mode. Have a damaged exahust manifold at 55,000. Dealer has sated that none of these are under warranty. I have heard of other people having same problems. I buy Toyotas for reliablity and service. I feel that I have not had the service nor the reliability expected. It would be a good sign of committment if totyota does honor a solution to these two problems, exahust manifold/exahust entering cabin.
