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.

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 Tundra.

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.

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 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.

Brake problems on 2000 Toyota Tundra. Since filing his complaint last year, consumer discovered his 02 sensor relay malfunctioned and the exhaust manifold was cracked. The sensor was burned and almost caused a fire. Consumer inquired whether these failures have been investigated and what's the possibility of a recall.

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. After approx. 3 months of trying to get Toyota to cover the complete cost to replace, they finally agreed to furnish the parts free of charge and I pay the labor of $662.18. I feel that Toyota should cover all costs.

Excessive vibration in front and rear brakes. Replaced/repaired by dealer several times until warranty period ended. Rotors and drums replaced twice by owner, including the installation of drilled and slotted rotors. Rear vibration persists. Toyota is non-responsive on this issue as well as others.

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. I was told that both exhaust manifolds were cracked at the repair cost would be $1600. The vehicle was out of warranty by about 5,000 miles. In the end, I was forced to pay $643.55 in order to have a safe Toyota.
