The truck would no longer go past 3000 RPM on some occosians. Vehicle code reader identified this vehicle's secondary air injection system required repair and that this is a known defect with toyota tundras. Toyota issued an extended warranty to cover vehicles impacted by this defect, code p0418. This is a safety issue due to loss of power especially if random and unknown times when pulling into traffic normally would allow time to accelerate safetly but due to the sais malfunctioning it could accelerate slowly and cause a collision.

Transmission slipped and vehicle lose of power. Dashboard all warning lights began to flash. Pulled to side of road. Turned off vehicle attempted to reset. Managed to get vehicle to nearby parking lot and out of traffic. Complete loss of power to drive train. Cause was power steering unit sensor per toyota. Toyota covered part in attempt to prevent this complaint. From internet, "some 2007-2008 toyota tundra vehicles may experience power steering dtcs p0552 and/or p0553. The power steering sensor has since been changed to correct this condition. The old/previous power steering sensor is p/n 89448-34010. This has been replaced with sensor p/n 89448-34020. Using tis techstream, confirm the condition by checking for dtcs p0552 and/or p-553. Disconnect the pressure sensor connector and proceed with removing the power steering pressure switch, which is located at the power steering vane pump and is mounted to the high pressure feed line. Install the new power steering pressure sensor, tightening to 15.2 ft.-lbs. (20.6 nm). With the new sensor fully installed and connected, start the engine and check for leaks. Adjust power steering fluid level as needed."

Code p2442 came up on my truck. This code indicates the secondary air injection pumps and valves are going bad on my truck. Also causes the truck to go into limp mode resulting in severe loss of power which can be dangerous in the wrong situation. My research indicates this is a known problem and very expensive to fix. Toyota will not fix the problem if your truck has over 150000mi or 10 years since first use. This affects all tundra and is a known problem. Toyota has extended the warranty on this issue twice, so they know this system is defective. I believe there should be a recall on the affected vehicles.

Was driving 08 tundra up hill around 20 MPH and cel vss lights came on lo range light flashing on dash truck lost all power. Found out code p2442 secondary air induction system failure put truck into limp mode thousands of dollars in just parts to repair this system. So many people having same problems with same vehicle. Toyota should issue a recall and re engineer a remedy for this poor design at no cost to the consumer. I spent alot of money on a truck to avoid these problems, now I have to drive an unsafe truck stuck in limp mode because I do not have the funds to repair, two thousand in just parts, toyota is charging people 4 to five thousand dollars to repair this problem when it should be recalled at no cost to the consumer due to the poor engineering and faulty design on the secondary air induction system pumps and switching valves......I am very surprised and disappointed in toyota for they have always backed up there product but this is a poor product that they are not backing up when they most certainly should stand behind it. Also this system should be redesigned to put on check engine light but should not put vehicle in limp mode it is a serious safety issue especially when trying to get on the highway etc..... Also the cost and problems of this unneeded system is outrageous, all this system does is force air into the exhaust for the first couple of minutes of engine running at startup. I swore by toyota for over twenty years, not any more , wish I got a chevy.

The engine check light came on and the engine went into limp mode, which reduces engine power making it dangerous to drive. The check engine light came on from the emissions valve set failing. When repaired by dealer they also discovered a cracked manifold. This emissions valve set failure seems to be very common on 2008 tundras and is very expensive to repair. To my surprise the manifold was cracked and that is a very expensive repair and may have contributed to the emissions valve set failure. Toyota should recall their emissions valve set and redesign it so it does not fail, and is less expensive to replace, and finally they should not program the engine to go into limp mode if this failure occurs, as it can cause you to lose power while driving in various conditions that require power to get off the road safely.

Emissions valve and related pumps failed causing a significant loss in power. This happened when traveling on the highway in upstate vermont. Suddenly my truck lost significant power, and would rapidly decelarate everytime I approach a positive grade in the road. Several times during the trip I slowed down faster than cars behind me expected, and the brake lights did not warn them as it was due to the truck losing power, and not me braking. In addition due to the location I was at I was unable to locate a dealer for several miles. When the codes were pulled for the service engine it appeared as code p2442 (secondary air injection pump system switching calve stuck open bnks)
