The truck has had three engine oil leaks since 4-20-22. The most recent is being repaired now. In each of these leaks, engine oil leaks out of the valve cover and or the cam tower and drips onto the exhaust. The burning oil can be smelled inside the truck cab. I am concerned it could cause a fire. The dealer has repaired the first two leaks and is working on the cam tower leak now (drivers side). I notified Toyota, they refused to fix the problem.

My truck drove fine then all of a sudden my check engine, vsc and traction control light came on. I brought it to the shop and the code read P 2440. It is in limp mode and the shifting is sporadic.

The air injection pumps went out. Vehicle could not get out of limp mode, was very dangerous as I couldnt get up to speed while merging onto traffic. Had to put hazards on and drive vehicle home under 25mph. Vehicles were going around me. Vehicle is scheduled to be looked at by a dealer, but still recommend this be a safety issue!!

Truck goes into low power mode or "limp" and has difficulty accelerating. The check engine light is on, “VSC OFF” light blinks on and off, as well as the “slippery tire” sign stays on. Very dangerous if this happens when driving on an expressway as you can't drive over 45 mph in low power mode. This is a known issue with Air Injection Pumps and Air Switching Valves for Toyota Tundra trucks between 2007-2008. Toyota extended the factory warranty instead of offering a recall. Due to the factory warranty extension Toyota would not fix this problem until it manifested, and it usually doesn't manifest until after the extension of the factory warranty has expired.

When accelerating on my truck between 45 and 55 miles, the motor starts shaking alot. I have to release the gas pedal to make it stopped. Also the transmission shift by itself when I am at a stop sign. Just once.

secondary air pump failure, truck has a tough time accelerating, I’ve unhooked the pipes and drained the water out the pipes but that did little good. The check engine light is on, “VSC OFF” light blanks on and off, as well as the “slippery tire” sign stays on.

Tundra won't accelerate as engine goes into limp mode which restricts speed capability of vehicle. This is related to air injection pump failure and related also to air switching valves. Limp mode on a toyota restricts speed at which you can drive, shifting and top speed are restricted. Slows to point if entering highway or trying to keep up with speed over 50 MPH could not do it. Toyota is aware and has a customer support program ztq buying vehicle used not aware of this or anything about it. I slowed traffic and caused back up on the street was traveling could nit do more than 20-30 MPH on road posted at 50 MPH. Glad not entering freeway. Plenty of u tube videos detailing repair and problem. The toyota documentation says 477,000 tundra vehicles were covered by this enhanced warranty program. Previous owner did complain to toyota and had computer replaced on vehicle.
