Tl* the contact owns a 2007 toyota tundra. The contact stated that the air pump and valve set failed which caused the vehicle to become resistant to acceleration attempts. The vehicle was inspected by a dealer and the dealer advised her that the pump and the valve set would need to be replaced. The vehicle was not repaired. The manufacturer was contacted and offered to pay for fifty percent of the repair costs. The failure mileage was approximately 119,000.
Sudden decrease in power , dash lights come on drove to dealer ship , they said it was the air intake valve that was bad they said it was a common problem they said moisture builds up and makes the intake valve stick they replaced the valve at a cost of $1,682.00 had I been merging on to the highway this could have been very dangerous for the vehicle will only power up to 35 miles per hour.
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 currently have two other tundras there with the exact same problem they.are "replacing the air injection pumps and valves for a total cost of ~$4000 if the vehicle is not under warranty anymore this is all at the owners expense. This is a dangerous problem due to it prevents acceleration and you have a sudden loss of power quite dangerous when merging or in a flow of traffic..
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!!!!!!
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.
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.
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.
My truck suddenly lost about 80% of its power and would hardly accelerate. Very difficult to merge into traffic. Dealer said this was due to failure of the "secondary air intake valve." this appears to be very common in 2007 toyota tundras.
Toyota tundra 2007 w/ 4wd. Vehicle went from normal 2 wheel drive into 4 wheel drive low without warning, without touching any controls. Could not drive faster than 30 MPH, engine check light came on. Turned into dealer, they said it was a component in the engine that failed. The warranty inspector came by today and the history data on the memory had been erased and could not duplicate. Vehicle is still in the shop. Dealer states it is defective but the warranty does not want to pay for the repair. The dealer stated air pump in the intake manifold failed. The consumer believe the problem may be the ecu.

Air pump is full of water. Dealer emptiest, it fills back up. Dealer has no explanation as to cause. Vehicle runs sluggishly. Need to allow extra time when merging into traffic due to poor acceleration. Dealer wants $3000 to replace unit.
Stuck gas pedal. The incident occurred over a year ago when I was driving on us101 highway near tillamook, oregon with two of my brothers, one on the front passenger seat, and one on the back. When I slightly press on the gas pedal, the truck took off with RPM at about 6000 and speed of about 70mph, and I could not stop the truck via pressing really hard on the brake. Finally, I was able to stop it by pushing the shift handle to neutral. I turned off the engine and checked the gas pedal to make sure nothing would get jammed, and I did not find anything. When I tried to restart the engine, the RPM shot to 6000 again, and this time I tapped on the gas paddle couple times, and the engine dropped back down to idle. Fortunately, there was no one driving in front of me, and there was no accident involving this incident, but I believed this is a major safety issue that need to get more attention from the truck manufacturer. Btw, I've not let my wife drive this truck since the incident occurred.
Toytota tundra 2007 speed went from 60 MPH to under 20 MPH. Car has since be diagosed with defective air flow handler, dealership wants me to pay $5,000 to repair this part. This situation caused a life threatening situation on the highway. This repair should be done at the cost of the manufacturer since the truck only has 63,000 miles on it.
Vehicle hard to stop with A/C or headlights on. Engine idles normally 5-600 RPM, until parking lights or A/C is turned on. Then it idles at 800 RPM in gear. Sometimes it feels like you've been rear ended, after coming to a stop. If driving surface is slippery and put into gear with head lights on, the rear tires will begin to spin, without touching the accelerator. This is a daily occurence that has been taken to different toyota dealers with no relief. All they can say is that the computer says everything is okay. Turning the parking lights on does not cause enough load on the engine to warrant the extra 200 or more RPM. The other day ( 01/26/2010 ) I was turning around in a muddy driveway and while idling I turned the steering wheel to the left. I let my foot off the brake and the truck went straight, even as I applied the brakes, leaving two big ruts through my friends yard. This was caused by the ground being slippery and the high idle speed. I am sure that this will cut down on the life of the brakes. 4.7 v8 engine
The 2007 toyota tundra double cab with 5.7 liter engine was experiencing vehicle traction control system malfunctions. After replacement of wiring harness, traction control ecu, wheel speed sensors the problem was not corrected. A factory technician was brought in to look over the vehicle. The factory technician informed me that the cause of the problems with my truck were because several sensors had lost calibration due to the battery being disconnected. There is no information in the owners manual nor any warning signs on the vehicle that provide any cautionary statements to the owner or a service provider that disconnecting the battery may result in the loss of calibration of sensors in the vehicle. Toyota motor corporation has clarified that this information is only in the factory service manual. A review of several toyota repair procedures, which require the battery to be disconnected contain no warning to check sensor calibration. The traction control system is one of the major safety systems of this vehicle. When it fails, the operator may loose throttle and braking control. I have had this vehicle shut down the throttle while I was trying to accelerate from a stop sign at an intersection, thus nearly causing a t-bone collision.
1. A section of air conduit fell across brake pedal. 2. Once, near death experience attempting to brake. 3. Removed part.
