The secondary air intake pump and switching valve stopped working after only 28,000 miles. Car went directly in limp mode making it undrivable. Dealer wanted $2,100. 00 for parts and labor and said it was not covered under the warranty.
After starting Tacoma, check engine light and "trac off" light came on, went into limp mode, could only go 30mph. Tacoma just hit 34,000 miles. Dealership stated secondary air injection valve stuck closed bank 1 (code p2441). Was told pump and valves needed to be replaced at $2100, including labor. Called Toyota corporate, told it was not covered under power train or emissions warranty. This issue actually first occurred approximately 4 months ago while driving on a city street. Warning light came on and went into limp mode. Pulled into a firestone and they said it was also code p2441. They reset it and it didn't happen again until a few days ago. This time the code would not reset, warning light won't turn off and remains in limp mode.
Check engine light came on and vehicle was not going past 2k rpm and over 20mph. Connected to an onboard diagnostic reader which gave me codes p2440 and p2442- secondary air injection valve stuck open bank 1 & 2. Vehicle has less than 50,000 miles and only 4 years old and Toyota does not cover faulty equipment under any warranty (powertrain or federal emissions) although they have issued canada TSB 3861 acknowledging the deficiency, but leaving the owner to pay $645. 00 for the replacement part from Toyota dealer. This is unsatisfactory- they must be held accountable for a vehicle still within powertrain (60,000mi) or federal emission (80,000mi) warranty.
The horn doesn't work. The problem has been diagnosed as "clock spring" and the cost to fix it is almost $500. This is a lot to pay for something that should never go out! relay and fuse checked out.
Secondary air injection valve failure at 53k miles, Toyota would not cover under my power train or emission warranty. Truck was put into limp mode when the failure happenned and was undrivable.
Secondary pump does not work when is cold turning trac and ing light on causing loose of power and hight gas consuming. Dealer says warranty does not cover.
Vehicle jumps from rear upon acceleration from stop position.
The truck started to make a rattling noise under the hood on the drivers side when reaching 15mph. Took it to dealer to have it examined. They said to try different gas not cheap gas. "I was already using shell gas" but I did what they said. Still making the noise now from 20-40mph. Take it back to dealer now they take a test drive with myself to verify the noise. Comes back that it has a tas case# there's nothing they can do about it. I call to file a complaint to find out there is no repair and they will not touch it till it becomes a recall. Just took it back for the third time because the rattling is louder and longer. Still did nothing. The rattling can get so loud that it sounds like something is going to fall out from under the hood.
