Engine Exhaust System Problems of Toyota Tundra - part 1

P024300 turbocharger/supercharger wastegate actuator a. The car was driving under 60 mph then a smoke started to appear from the exhaust. Then there was a noise coming from under the engine. After reaching the destination the dash screen messages was saying the engine power has been reduced and the car should visit the dealer.

The Toyota 5. 7l v8 engine found in Toyota Tundras, sequoias, siennas, land cruisers, and Lexus lx570s suffer from cam shaft tower leakage, and it will most likely happen to anyone that owns one. It can happen anywhere from 1k miles to 100k miles, but it can damage the engine and other important parts and therefore should be recalled. It is also a safety issue, as it leaks in to the exhaust and could cause a fire. I own a 2014 Tundra that has this issue and the dealer wants me to pay $3k to fix it!.

Case # [xxx] ( filed with Toyota) on Jan 3rd while returning home from having brakes replaced on my 2008 Tundra my vehicle engine died on a busy 4 lane road with heavy traffic. I lost my ability to steer immediately. Fortunately I was in the right hand lane and was able to pull into a parking lot before I lost total momentum of the vehicle. I tried restarting and it would not. I checked all the indicaters and everything appeared normal. Fuel gauge registered 1/4 full which would equate to approximately 5-7 gallons. After exhausting all efforts to restart the truck I called for a tow truck. When the tow truck arrived I explained to him what was happening and he suggested it might be out of gas!!!. . . I showed him the fuel gage indicator showing the 1/4 level and he told me that his dad also had a Tundra and had experienced issues with the fuel tank float hanging giving false readings of what the actual fuel level was. He suggested we take the truck to the nearest gas station and put a few gallons in prior to taking the truck to the service department. Once we added some gasoline the truck started right up. I was shocked and upset for a number of reason. 1. I just paid a tow service $75 dollars for taking me down the road about a half block to a local convenient store to put gas in my truck. 2. I started realizing what a dangerous safety issue this is. I could have just as well been traveling down the highway at 70 miles per hour and have my engine just quit on me!! the ramifications of that are quite scary as to all the accident scenarios that could occur to include loss of life for not only the driver of the failed vehicle but those traveling close by as well.

The contact owns a 2006 Toyota Tundra. The contact stated that the vehicle would not accelerate after being stopped at a light. The vehicle was driven to an authorized dealer in limp mode where the contact was informed that the failure was the result of water intruding into the engine air intake system. The dealer also stated that the intake manifold would need to be removed, the upper half of the engine would have to be dismantled, and the valves would need to be replaced. The vehicle was not repaired. The approximate failure mileage was 97,000. The VIN was unavailable.

2 air induction pumps (aip) and associated values failure around 60k miles. According to Toyota the reason for the failure is moisture. New pumps and valves can be installed for $4000 or if you are lucky and you only need to replace one pump and both valves it only cost $2150. The new pumps and values have been modified so they should not failure as fast as originals. If the new pumps and valves had to be "modified" then it leads one to believe the originals had a design flaw.

2007 Toyota Tundra 4. 7l engine p2442 code engine in limp mode. Secondary air intake valve failed in open position. 62000 miles. This is a known defective system that fails if driven in wet conditions due to poor air fan intake design. It sits in the wheel well and is wet all the time. This leads to water being pushed into the air valve causing it to fail.

2007 Toyota Tundra went into linp mode. Error p2442 reported. 75k miles on truck with air induction system valve sticking due to what appear to be water intrusion. The failure started out intermittently, thne became consistent. Cost $1000 to replace both valves in each air induction bank. Worried that the pumps will fail in the near future. Unhappy Toyota customer. Poor engineering design.

2007 Toyota Tundra 4. 7 approximatelu 124,000 kms engine went inito limp mode. Dealership diagnosed problem as air pump and valve bank failure, $4700 repair estimate. Not covered under warranty becuase over 100,000 kms. Also purchased extended warranty on this vehicle however these parts are not covered under the extended warranty. (go figure) pursued the emmissions warranty which covers emmission control parts, however Toyota claims this is not part of the emmission system even though the air pump controls emmissions at vehicle start up. Took the pump off the vehicle and drained the water from the poorly designed system, lubricated the pump and got it working. Truck went back into limp mode after a couple days now apparently valve bank is stuck. Toyota still reccomends replacing all the parts for $4700. Not happy with Toyota this should be a recall the pump is located in the fender well directly in front of right front tire, the intake pipe for the pump is designed so that any water present goes directly into the pump cuasing the system failure. It would be a pretty simple fix for Toyota just put a 90 degree bend in the pipe so that water cannot get in and reposition the intake hole. Trying to sell Tundra if anyone is interested.

2008 Toyota Tundra code# p2443 air injection system switching valve stuck closed bank 2. Truck went into (limp mode) causing little power in heavy traffic. Toyota dealer says min. $2000 fix for two pumps or a switch valve . Lot of people with same problem, needs to be a recall.

Noticed oil in drive way looked under truck and notice my steering rack was leaking and stabilizer links were rusted off. Took to mechanic for repairs and he informed me my whole exhaust was rusted as well as the body. Took to a Toyota dealership back in 2009 for body rust recall and was told it was ok. I now no that was not true.

2007 Tundra had a history of loosing power, took it into dealership and they found air injection pump and valve set were rusted and full of water. At a cost of $2000. 00, and this is for one side only, the other side can go at any time. I understand these are not updated parts and will need to be replaced again. All out of my pocket. Besides being a safety issue, this a costly repair for what I consider to be a defective system. This needs to be a recall issue!!!!!!.

2007 Toyota Tundra has air injection failure which puts the truck in "limp" mode or no power. I was entering the expressway and could not get my truck above 40 miles per hour. I was able to pull onto the shoulder to avoid a major crash. Toyota is aware of the problem but charges $4000 for the repair. My truck has been at the dealer for over 6 weeks. This is due to impart to a national recall. This seems in my opinion as a way for Toyota to profit from a faulty design and a potential life threatening condition.

Air injection system failure causes a check engine light to appear and can cause the vehicle to go into "cripple" mode limiting throttle and speed to 40 mph which could be a serious safety concern in some driving conditions. Dealer stated they are "fixing" ~2 vehicles a day and replacing the air injection pumps and valves for a total cost of ~$4000 if the vehicle is not under warranty anymore. In my case, the dealer replaced one pump a week ago and now the second pump has failed ($1100 for each pump). There has not a design change to the pumps or valves in the system with the replacement parts so the failure will happen again in another 30-50k miles. Dealer claims moisture in the system is causing the problems. A quick google search on the problem shows the problem is systemic with 2007+ Tundras and sequoias with the 5. 7l v8. Other manufactures use an air injection system with a much lower cost and there does not seam to be any problems with them.

Vehicle loss of power, unable to pull out safely in traffic.

Toyota Tundra 2007 loss power . Dealer was testing air pump assy for bank2 and emission control valve for both banks need to be replace . It will cost $ 3000.

2008 Toyota Tundra. While driving at 65 mph, I had a air induction valve fail all of a sudden which caused my vehicle to suddenly stall into limp mode. I know this part has to do with emissions but how it caused the vehicle to respond when it failed if very dangerous. I was in heavy traffic and this sudden switch to limp mode caused me to basically loose control for a few seconds in bumper to bumper traffic. It was very dangerous as the vehicle suddenly dropped to about 35 mph with no control . Traffic was swerving around me and honking their horns as my vehicle suddenly dropped from 65 mph to 35 mph. I understand parts will fail periodically but the way the vehicle switches to limp mode when this particular problem occurs needs to be redeveloped and fixed or some serious accidents are going to be the result. I have found that this is a more than common occurrence with Toyota Tundras in the 2007 and 2008 years. Thanks for you attention to this matter.

My wife came very close to getting into an accident while bringing the kids to school a few weeks ago. She was leaving a stop sign getting onto a very busy highway when our 2007 Toyota Tundra unexpectedly had drastically reduced power. After a trip to the dealership and some research I have found that the reduction in power was caused by a failure in the secondary air injection system. This system is part of the emissions system and is designed to increase efficiency during cold starts. When there is a failure in this system the ecm (onboard computer) goes into a mode in which the available power from the engine is dramatically reduced. Toyota has recommended that I replace two air injection pumps and a switching valve set at an estimate of over $3500. I am researching other options because they tell me that this problem can continue to reoccur over and over again.

I have a 2000 Tundra access cab truck with 62,000 miles. The check engine light came on so I had it diagnosed. The front O2 sensor before the cat has failed. I wrote Toyota and they said that they had extended the warranty to 7 yrs or 90,000 miles. They said that it was also up to the local dealer to decide if the fault would be covered. I purchased this vehicle from a relative, who is now deceased, and did not receive any recall info. I wrote to Toyota and they told me to talk to my local dealershp. I talked to the local dealer and they told me to write or call the Toyota experience department, or what ever it is. From what I have read there are a lot of people getting ripped off for a defect in factory provided parts and replacement parts. I definately think this is a design flaw and should be covered by Toyota. I for one can not afford to own a vehicle that is going to cost $200. 00 to $800. 00 every 6 months to 2 years. This also affects the environment and the fact that this vehicle has to be smogged every 2 years.

I took my 2001 Toyota Tundra to the mechanic because the exhaust system was getting noisy. When the mechanic had the car jacked up, he noted that the frame was extremely rusty on the driver's side in front of the back tire. It was actually almost rusted through. He said it looked like it could break at any minute and got away from the vehicle. I contacted the dealer where we purchased the truck who said I should drive it down for them to inspect it. I refused because of the safety issue nothing has been done at this point and the truck is still at the mechanics.

Check engine light came on. Dealer checked the fault codes and told me both oxygen censors had failed, and that they had to be replaced to pass NY state inspection. Cost over $600. 00.

At 80,000 miles my transmission needs to be replaced . I have never abused this vehicle in any form and feel that Toyota should reimburse the many thousands of owners who seem to be having the same problems with this model. For the amount of money these vehicles cost it only seems fair that Toyota should be forced to stand behind their products.

Cracked exhaust manifolds, have heard the noise for quite some time. It has gotten worse but goes away when the truck warms up.

My 2000 Toyota Tundra limited v8. . . O2 sensors need replaced (all 4 of them). . . This is an apparent problem and should be a factory recall item. This is a $850 dollar job. . . Ridiculous! check engine light comes on and codes out as oxygen sensors.

2001 Toyota Tundra limited v8 4x4, currently at 39,400 miles. At approximately 33,000 miles - 2 years ago - I took the truck into the dealership for a loud knocking at cold start-up. They were "unable" to reproduce the problem even after leaving the vehicle for two days. The next visit for service, I had cracked exhaust manifolds, but was told I was out of warranty and it would be about $1700 per manifold to replace these. I purchased quality aftermarket manifolds and had them installed by an independent shop for less than $1,200 for both sides. I now see where many, many others have had this same experience and believe the original manifolds to be faulty. Toyota needs to either make the repairs under warranty, or reimburse those of us who paid out of pocket for replacing defective, poorly made manifolds.

Both left and right exhaust manifolds are cracked and leak exhaust gases into passenger compartment. Right exhaust manifold has been replaced. Because of cost, left exhaust manifold has yet to be replaced.

I bought a 2006 Toyota Tundra sr5 back in 2007. I have had my vehicle serviced every since I have bought it. My truck has always smelled like rotten eggs and I have had the injectors cleaned 4 times since I've owned it. The problem still exist. I have contacted Toyota about this and they say there has been no recall. . . Please look into this problem and also the tire pressure warning system light keeps malfunctioning. People spend too much money on these vehicles and last thing we all need is to fork out more money on a vehicle that is more less in a nut shell a lemon. Everytime I turn around it's something wrong with this type of vehicle. Thanks for your time and look forward to hearing about this problem.

: the contact stated at 20,000 miles while applying the accelerator at various speeds there was a spewing noise and the odor of fuel coming from the vehicle. The vehicle was taken to the dealership, which determined the exhaust manifold needed to be replaced. Although, the exhaust manifold sensors on the passenger side were replaced three times the exhaust manifold had never been replaced. The odor became worse and now is causing dizziness and headaches to the occupants. Updated 7/3/2006 -.

I have an oxygen sensor failure. Don't know if it's one or both on the right side. Will cost well over $400 to fix. Have heard of several other having the same issue.

3 pairs of cracked exhaust manifolds in less than 100k miles. Had I been more vigilant about repairing them as soon as they occurred, it likely would have been another couple of pairs. Dealer replaced them up to 100k, and although I pressed them for a solution, they would not honor problem after 100k miles.

The headers near the engine have little holes in them allowing there to be an exhaust leak and a loud noise.

When driving consumer smelled fumes coming from the vents, causing the consumer's eyes to burn, and making it hard for the consumer to breath.
