2008 Toyota Tundra engine problems

“The contact owns a 2008 Toyota Tundra. The contact stated while driving 50 MPH, the vehicles stalled. The contact stated that the vehicle hesitated and failed to accelerate above 50 MPH. The check engine warning light was illuminated. The vehicle was able to restart, but the failure recurred. The vehicle was taken to the dealer where to be diagnosed. The dealer determined that the secondary air injection pump had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The approximate failure mileage was 116,000. The VIN was not available.”

“The contact owns a 2008 Toyota Tundra. The contact stated while driving 20 MPH, the vehicle stalled. There were no warning lights illuminated. The contact called an independent mechanic, but no assistance was provided. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.”

“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.”
