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.

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.

The truck would no longer go past 3000 RPM. Writer drove the truck home. It was then taken to tarbox toyota for evaluation. They notified writer that the 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. Cost to repair is $2300. Toyota will not assist me with this issue but advised me to stop driving the vehicle. So they are aware that this defect is dangerous yet will not repair it under said warranty. I called toyota headquarters and they were of no help. I am a nurse who works in a hospital during this pandemic and I no longer have reliable transportation to get to and from work. This is a known defect where toyota extended their warranties to cover this. However they refuse to assist me. Now I am stuck with a truck that cannot go past 30mph and its emission system is no longer functioning.

I have a 2008 toyota tundra. The secondary air pump failed on my vehicle. I took it to the dealer and was told I would be $3500 to repair. This is known problem with the tundra. I was told by the dealer that toyota had extended the warranty for this but it expired after 10 years or 150,000, I have 121,000. When the pump fails it causes the vehical to go into limp mode. I ran a errand today and the truck ran fine. I went to the store and returned to the truck. I started it and the the vsc light and check engine light came on. As I headed into traffic the vehical would not accelerate to keep up with the traffic and almost got rearended. Toyota should of had a recall on this because it is a safety feature and could cause a serious accident. This air pump is installed on tundras and other models. I bought this truck new in 2008 and have serviced it on the mfg schedule. Since this was a known problem toyota should have replaced the pumps during regular maintenance instead of not doing nothing and hope it does not occur. Even if I replace the pumps what says it won't happen again. I lost confidence in my truck and am afraid it might happen again.

Check engine light came on. Codes indicated failed secondary air intake valve. Took it to dealer who said I was one day outside of extended warranty. No warning of any consequences of not immediately addressing. Driving home on interstate truck truck suddenly had several warning lights start to flash and would not accellerate above 35. I was trapped in substantial truck traffic with nowhere to pull off and couldn't even climb hills without power decreasing further. Found out this intentional. Truck was put in "limp" mode by programming. To restrict speed and accelleration without warning for a nonessential fault which is not a threat to engine operation is insane.

Started vehicle. Would not shift out of park. Released lock manually and drove to dealer (6 miles). They replaced fusible link and found ABS controller not working. I was told to drive home and they would call 4 days later on availability of used controller ($300 vs $1953). Brakes ok but no ABS. Had same thing happen august 31, 2014. Had the tundra hauled to dealership. Tundra was at the dealership for a month waiting for replacement fusible link. Backordered - out of stock all the way to japan. Toyota had to manufacture more. More than expected demand? Both times warning lights for brake, check engine, ABS, air bag were on. Turn signals and speedometer not working. Dealership told me they had no idea of the cause. Told them low voltage caused this to happen to another vehicle I have. Makes me wonder if there are being truthful with me and if other safety systems may be compromised.
