The 2007/2008 Toyota Tundra has a design defect with its air injection pump that allows the pump to injest water when driving for an extended period in rainy weather especially at highway speeds. When the water is then transferred to the switching valves. The vehicle will loose speed rapidly on a medium grade with no ability to accelerate. The cruise control causes the tranmission to downshift repeatedly trying to accelerate. This is extremely dangerous at high speed. In addition the vehicle stablization control is disabled. This condition also short circuits and disables 4W drive and cause the check engine light to come on. The inability to maintain speed or to accelerate creates a very hazardous condition. I have had this problem corrected twice at a cost of $1600. The dealer has informed me that the problem will continue to occur because of a design flaw. Toyota acknowledges the problem in a service bulletin to the dealership (T-sb-039-08 rev 2 dated 10/28/08). There is a remedy for this problem but the dealership claim it has no authorization from Toyota to implement it. As a result I am forced to drive a vehicle that becomes unsafe when it rains.

I have a 2008 Toyota Tundra with a 4.7 L engine and 5 speed automatic. On two separate occasions, I have had the truck in park on a very slight incline, and the truck has suddenly started rolling backwards.

- Greenwood, IN, USA

While in park and with engine running and parking brake engaged, after about 5 seconds vehicle suddenly rolled backwards down an approximate 10 degree slope and crashed into a building. My wife and 3 children were in the vehicle (fortunately all were wearing seat belts) and suffered minor injuries.

1. turning right in 2008 Toyota Tundra out of parking lot at work or into traffic, I decelerate preparing to turn right and remove pressure from gas pedal and brake during the turn. When I reapply pressure to the gas pedal during the turn the truck does not accelerate only the engine accelerates. Adding additional pressure to the gas pedal only causes the engine to accelerate more. When the transmission engages the truck surges forward suddenly. 2. this slipping in the transmission happens every day. The consequence of driving this vehicle is when will the transmission slip and when will the transmission engage. 3. have talked to the dealer (2) two times about this issue and the dealer tells me it is normal for this vehicle to react in this manner. The dealer says there is nothing they can do about this problem.

The transmission and transfer case on our 2008 Tundra 4WD drive has failed, repeatedly this past week while operating the vehicle on a public street. In this "fail" condition, the transfer case makes a grinding nose, the transfer case alarm buzzer makes nose and irrespective of transmission position or transfer case selection (2wd, 4WD hi, 4WD lo) fails to engage in low or hi, and most troubling, the vehicle will roll in any gear, no gear will engage, and the car can roll forward or backwards out of control. I was almost hit a by a car today because I could not get the truck to engage in any gear, in any setting, inspite of attempts to roll the vehicle slightly down the hill to allow for the transfer case to engage, as suggested in the owner's manual. While I am not pleased with the (failed) condition of the drive train for this new truck, this is an issue I will address directly with Toyota. In the fail condition of 4WD, the transfer case merely 'beeps' and refuses to engage transmission, resulting in a free-rolling, uncontrolled vehicle. Had this failure happened today as we attempted to enter the freeway, we would have likely been in a accident. This is unacceptable. I am most concerned that other Tundra owners (and the similar sequoia) would have a loss of vehicle control and power, resulting in injury or death. How troubling Toyota would put this vehicle on the road without addressing this issue.

Truck was in cruise control. Accelerated to pass slower traffic. Let off throttle. Truck went to full throttle. Could not get truck to decelerate. Had to stand on brakes to bring to a stop. Truck needs new rotors and pads Toyota will not help. Occurred once. The consumer stated the floor mat and gas pedal can interact. When the all weathr mat is not clipped in place, and is moved under the gas pedal, it will become fully depressed. The mat can trap the pedal. Updated 11/13/09 updated 03/29/10
