general problems of the 2012 Toyota Tacoma

The check engine light on the dashboard of my 2012 Tacoma turned on and will no longer accelerate appropriately and especially while driving uphill, posing a danger to myself and other drivers. I was on a two-lane highway with a cliffside drop on one side and a wall of steep rock on the other and absolutely no where to go as there was only one lane going in each direction and my truck would not accelerate over 20mph in an area where you’re expected to keep a pace above 40mph and as such ended up with a long row of impatient and increasingly frustrated drivers behind me, only more incited by my having to turn on my hazard lights as a result of a crawling speed I was forced to deal with and with nowhere to pull over and get out of the way. How can I possibly rely on this vehicle to be safe for me or anyone else, especially on a fast-moving highway in this condition? I have taken the vehicle to an auto shop and I as told the air injection system is bad and that this is a typical problem for Toyota Tacomas and the cost would be just shy of $3,000! I was recommended by a mechanic to reach out to Toyota directly because this is obviously an issue the manufacturer should readily respond to and repair. Please advise.

My truck lost drivability while I was going 60 I ran into a ditch to stop. It hads two codes . I took it in they replaced my rack n pinion. Check engine light came on . Mechanic said he could not work on it anymore because of the rust. To much corrosion he would be risking liability for other parts getting damaged because of all the rust. Took it to mike shaw to have frame tested. It passed they said. But I can’t find a mechanic to work on it but mike shaw and they’ll just keep charging for each item they don’t care.

Switching valve stuck open bank 1 and 2. Truck is in limp mode. Air pump is full of water.

When accelerating the truck lost all power and acceleration. Engine light is on. Engine will not increase rpm when accelerator is pressed. Truck will slowly drive but is unsafe to be on the road as it slowly accelerates up to 20-30mph max. Vehicle was merging into traffic from parking lot access.

Trac off and cel on, truck goes into �limp mode� and decelerates when gas allpied. Loud whining noise when first starting.

My check engine light came on and I had no acceleration beyond 20 mph. I took it for a diagnosis at auto zone and they told me it was codes ,2450 and 2442, secondary air valves stuck open. I am stuck in an unfamiliar city and no mechanics with time to fix it, to say nothing of me not having the funds to pay for the repair. The light came on when I was turning a corner on a hill. I understand this has become a very common problem for Toyotas and I would have expected a recall notice so that Toyota would fix the problem! I have no way of getting home as part of my drive is thru a very steep and treacherous canyon.

I'm a owner of Tacoma pre-runner 2012. I recently took my car to scan since I had the check engine light on. Attached I send you the codes and I also include the fact sheet delivered to me at the service center. I want to know if this is covered by any warranty.

Secondary air injector failure. Valves stuck open. Check engine codes p2442 and p2440. Vehicle in motion driving 70 mph on the interstate. Just bought yesterday with 47k miles. Failure causes vehicle to �limp�. Can't exceed 2500 rpms very easily, massive loss of power.

Cold start of the vehicle was followed by a high pitched whine and then the check engine light and �trac off� lights illuminated. Diagnostic check revealed faulty secondary air pump and switching valve. This problem has been acknowledged by Toyota for the tundra and the sequoia, but they continue to play dumb on this model year Tacoma. A cursory search of the internet reveals this is a widespread problem in the 2012 truck. There are dozens of reports of vehicles failing to accelerate, which is obviously a cause for concern, and the $2000 recommended fix is being done with the same improperly engineered parts.

I start up the truck and pull out in to the street. Whether at an intersection or making a turn, I push on the accelerator and nothing happens. The rpms don't increase, engine makes no sound - and I am left sitting in the middle of the road. I push the accelerator to the floor and eventually the engine comes to life and the truck moves forward. Happens more often than not when the vehicle is "cold" - within the first 20-30 minutes of operation. The accelerator is not linked directly to the engine through a cable but is a drive by wire. I have maintained my Tacoma meticulously since purchase including tune ups, oil changes, etc. I have cleaned the mass air flow sensor with no change. The problem still persists. It is very dangerous to be in the middle of an intersection with a vehicle that has lost power.

Check engine light on, trac off light on, engine power weak check engine code- p2441. This has been a common issue with Toyota suvs, and trucks! car is put into limp mode. Extended warranty on tundra with same part problem. Not Tacoma. Shameful and dangerous for Tacoma owners.

Secondary air pump failed at 47,000 miles, shortly after warranty expired. It failed as I was pulling out onto a major fast-moving highway and promptly went into "limp" mode, limiting acceleration. It took over a half mile to get the vehicle to 40 mph. Meanwhile, vehicles behind me were braking abruptly to avoid colliding with me. As I understand it the secondary air pump is part of the emission control system and I don't believe that this should effect the performance of the engine in this manner. This seems more like a software induced failure, which, in this case, caused a potentially dangerous situation. After some back and forth Toyota agreed to refund me 1/2 of the $2500 that I was charged for the repair. Upon searching the internet, I found dozens of instances of this failure on 2012 Tacoma's with similar mileage.

While driving on the freeway my vehicle lost partial power to the engine. I took it to the service center and they ran a diagnostic saying that I have a "failed engine air system pump and valve. " it was very dangerous loosing control of the speed of the vehicle on the freeway.

2012 Tacoma with 24k miles. Check engine light and trc light came on with truck in limp mode when I started it to go to work. Codes p0412 p2433 p2438 p2442. Toyota wont cover this and its a defect in many many 2012 Tacomas.

Emissions air pump valve went out with 60,200 miles on the truck. The truck is bone stock and has been very well maintained. After research its seems that numerous people are having issues with this same exact part on the 2012 Tacomas. Toyota extended a recall on the tundra's because of this part, but not the Tacomas. The truck is currently in limp mode and will not go past 40mph, and the dealer wants $1,075 to fix it. This occurred on my way to work this morning while getting on the freeway, and was quite scary to not be able to go over 40mph on a bay area freeway with cars honking and flying past me.

Check engine light on, trac off light on, engine power weak.

Secondary air valve sticks causing loss of power,,emission system while driving and stays on.

Check engine and trac off indicator lights came in, and vehicle went into fail code mode also known as"limp mode" while driving down a town road. Vehicle was unable to accelerate above 40 mph. Managed to get vehicle to dealership, was told the problem was a "secondary air pump and valve". Vehicle has 56,700 miles on it. Toyota was contacted and a complaint was filed, but they would not acknowledge a fault in the part in this model vehicle. Toyota tundras have had the same issue and Toyota provided a fix for this model. When asked if the replacement part would fail in 50,000 miles I was told that the new part was "updated" so it shouldn't have the same issue. Why did Toyota allegedly update the replacement part if there was no faults in the original part?.

While on highway doing 65mph, vehicle slowed to 50, to 40, to 30, to 20 by itself. Pulled over, placed back into gear, vehicle only went 40 mph downhill, 20 mph uphill. Drove to Toyota dealer who said this was third Tacoma this week with faulty second air fuel injector. No recall yet, but 3 weeks for back order of part. 43 others before my part request. Same part on recall for tundra model. Safety was compromised on highway because of automatic deceleration.

My Tacoma tends to surge forward when it is stopped. I do not think it has anything to do with the air conditioner being on. I had the a/c off the first time. If someone isn't on the brake firmly they may tap the vehicle in front of them.

Fuel system can be heard hours after the truck is parked, few times a week and sometimes daily . And runs 2 to 15 minutes. Contacted dealer and says it normal for fuel evap to do a system check. Ongoing started before 3000 miles.
