2007 Toyota Tundra Owner Comments

problem #10

Feb 102011


  • 70,000 miles


2007 Toyota Tundra 4.7. approximately 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 because 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 emissions warranty which covers emission control parts, however Toyota claims this is not part of the emission system even though the air pump controls emissions 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 recommends 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 causing 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.

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 went into limp 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, then 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 4.7L 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 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.

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, 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!!!!!!

Tundra 8-cyl

  • 32,932 miles
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+ Tundra 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.

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.
