general problems of the 2012 Toyota Tacoma - part 1

The contact owns a 2012 Toyota Tacoma. The contact stated that while driving, the vehicle failed to exceed 45 mph. The contact stated that the check engine and traction control warning lights were illuminated. The vehicle was taken to an independent mechanic who informed him about a special service campaign: 20tc01. The vehicle was taken to the local dealer where it was diagnosed and determined that the air injection pump needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and informed him that the special service campaign: 20tc01 had expired. No additional assistance was provided. The failure mileage was approximately 85,000.

June 1st 2021 I went to park in a parking space at a local mall. My truck instead of stopping it accelerated out of control jumped two stone curbs, drove though a fence and landed into a swamp. Call Toyota and they have opened a new case # 210602000065. Police report # 21-374-ac. This isn't the first time that this has happen with this truck. It happen in Aug 2019. I contacted Toyota case number 1908060035. They sent out eaa engineering analysis ass. Out who did a acm. Cdrx file a month later. Toyota came back said they couldn't find anything wrong and my case was closed. Another incident in winter of 2016 where my truck was stopped and it accelerated on its own and it drove in the 4 way intersection where it caused an accident. Lots of damage to cars. Toyota was contacted and they sent me to a dealer for repairs. Dealership has records of my truck coming in since I owned it with complaints of truck not moving at all to all of sudden to acceleration on its own.

I brought truck to Toyota dealership as part of rusted frame recall to be verified. They stated truck was not rusted enough underneath for Toyota to approve recall. That was a couple of months ago. I have recently brought it to a few mechanics to do some work on a/c as the a/c stopped working and that refuse to work on it as the truck is so rusted underneath!! they said it would crumble. Not even worth it.

My 2012 Tacoma warning light 1) engine and 2 trac off warning light came on and lost power going 65 mph on freeway and would not go over 25 mph (dangerous!). Obd-ii scanner displayed error code check p2442 indicating faulty air injection pumps and/or air switching valves.

On my 2012 Tacoma the code p2440 and p2442 which represent a stuck open valve in the secondary air injection system. Upon my research into this issue on forums I have learned this is a common problem with the Toyota systems particularly the 2012 Tacoma. The cost of the part is about 400 to 500 dollars for the valves and another 500 dollars for the secondary air injection pump. The failure will place the vehicle into a limp mode and has to be fixed in order to the truck to keep on good working condition. It seems like this error has affected many Tacoma owners.

I was on the the highway today and suddenly I lost power and won't pass speeds over 40 mph very dangerous have heard this happend to a lot of Tacomas/ tundras and has to do something with the emissions I think I need a new diverter valve which Toyota should cover.

Cil and trac illumination with codes p2440 and p2442 caused the engine to go to limp mode with loss of power.

Known issue with the secondary air valve. Throws the code p2442 vehicle goes into safe mode. Dealerships want about $2,000 to fix it. Recommending the fan-blower as will to double the amount. This is known issue from all that I have read and the dealership that I purchased it from in va last year didn't mention this at all or offer any kind of warranty to cover potential issues.

Having trouble with my vehicles secondary air injection system, replacement parts are super expensive and have seen many people have the same issue, seems like a non-reliable component. Always get the fault codes p2440 and p2442. I strongly beleive that this is a defective component.

The check eng & trac off light came on while I was on the interstate and almost got struck from the vehicle behind me. My truck went into limp mode & slowed down to 2500 rpms & wouldn't go any faster than 25 mph!! this is a hazard as I have read other complaints about this happening to others, it is a known issue to Toyota, they have repaired the tundra's but so far am not showing any recall on the Tacoma's. Error p2442 secondary air injector failure. This is the 2nd time this has happened to me. Scary! please beware 2012 Tacoma owners! merry christmas to me! $2000 repair!.

83k miles. Eng light and trac lights comes on, while driving truck goes into limp mode and will not excelerate past 2500 rpms and will not go any faster than 35 mph. Error code p2442 secondary air injection system switching valve problem. Very dangerous problem.

While driving the vehicle in a suburban area it lost power, slowing to 25 mph maximum, I was almost rear ended. I swerved off the road into the grass to avoid being hit. There is a problem with the emission system. It is the secondary air injection system. Toyota has been aware of this problem for some time. Some of the 2012 Toyota Tacoma's have a customer support / warranty extension for this problem, not mine.

75k miles. Cel light and trac off lights come on, truck goes into limp mode and will not accelerate past 2500 rpms, and will not reach speeds above 35 mph. Very very dangerous and endangers not only the trucks drivers, but other drivers on the road. This is due to a faulty diverter valve that is a known issue that Toyota has issued recalls on for other models with the same problem.

Air injector pump causing engine light and trac light to come on and sudden loss of power. Vehicle in motion when occurring.

Secondary air injector system switching valve problem at 55000+ odometer.

Went on vacation to texas, stopped to gas up and when I went back on interstate I had a dramatic loss of power. Could not keep up enough speed to go speed limit. Air conditioner did not work. At destination a local told me about a repair shop. Cost me a hundred dollars to reset to factory specs. This has happened again four other times. I disconnected battery and reset myself. Now it`s a daily thing.

The secondary air injection system went out.

Almost lost control of vehicle when the trucks performance jumped into limp mode "trac off" as I was driving. Loss of speed and performance caused me to be a driving hazard. 2 vendors today found the codes p2440 and p2442, which appear to have triggered my truck into "trac off" and "check engine" light on. Mode causes my truck to only drive about 45 significantly impacts performance and dangerous to drive. This is a safety hazard,I had no warning that the loss of performance was going to happen initially when I was traveling. There is another problem that appears to be on a larger scale. I have briefly scanned the internet in the last hour and spoke with various vendors about the problem & I have called my dealership & even the main Toyota line and everyone is aware of the issue. The codes are p2440 & p2442. After finding out the codes I looked at the air injection pump & I was astonished to see that the pump was completely full of what, like someone literally took a waterhose & filled it up. Logically, this is why the air injection switching valves 1 and 2 are both stuck open one code for each of the valves. The next thing that is unusual is that there are an incredible amount of people having this same problem but no recall. . Then I found the tundra recall for the exact same pump issue! it is peculiar, that a different model truck with the same pump has this problem & no recall or remedy. Fact-tundra is a more expensive truck than Tacoma, is Toyota fixing public relation issues for those more well off because they know how to complain to the right folks or cause a big stir and they will hold off on pulling the trigger on a "warranty fix or recall" on the working mans Tacoma? this is just an opinion but my intuition tells me this is intentional. The fix is approx $2000 I am stuck driving 45 mph till then with shady steering & performance. #accountability #me too.

39k miles throws codes relating to secondary air injection pump. $2100 quote to fix. Many other owners with the same problem.

Oem parts failure due to manufacturers defect. This exact issue prompted recall of the Toyota tundra. Dealership reports numerous customers with same issue. Repair is over $2,000. This is serious issue. Air injection pumps and switching valves are faulty allowing water into the system and causing the engine to seize up and decrease engine speed. This happened on I-90 in heavy traffic causing other motorists to apply breaks quickly. Contacted Toyota and they are aware of the issue but have no plans to initiate a recall.

My 2012 Tacoma is throwing lights on for a new secondary air injector valve , parts p2440 and p2442. The Toyota mechanic said this is a common problem with these over the past few years as the 2012's hold moisture after shut down and the valves break down. I see this is a common problem online and a very expensive fix for us all. This should be covered fix, just because it doesn't cause in imminent health hazard doesn't mean it's not a problem that Toyota should cover. The issue with the vehicle once a sensor detects this problem is that it puts it in a limp mode, and makes the vehicle very sluggish even difficult to achieve 45 mph.

I was pulling out on to the highway and my truck failed to exceed 30 mph with oncoming traffic which nearly caused an accident. Upon inspection by my Toyota dealership, they explained that my secondary air injection valves were stuck open (p2440, p2442) which caused the truck to lose all power. I was then told that since I am no longer under warranty (my truck is only 5 years old with 48,000 miles on it) that Toyota would not cover the 2,000 dollar cost to have the part replaced. Upon further research, countless others were having the same issue. The Toyota tundra also had this issue and an extended warranty was offered for those vehicles. Since Toyota knows this is an issue it is my belief that they should stand by their product and fix the defective part which is a huge safety issue as I found out. Furthermore, there is no reason this emissions part should ever shut down the power to the truck while driving. Thank you for your time.

Error code p2442 secondary air injection valve stuck open. Truck immediately goes into "limp' mode and will not accelerate over 20mph. Extremely unsafe to have the vehicle decelerate on a highway for a known issue that has prompted warranty extensions on Toyota tundra's.

Secondary air injection switching valve malfunction related to emissions. Code p2440 & p2442,.

While commuting to work the engine light and traction control light came on, causing my truck to slow down, very slow. It would not let me accelerate and disabled my progress to around 2000 rpms. This could have been a very serious or a dangerous situation especially if I was towing a load or in a major traffic situation. Codes - 2440 and 2442 were the causes of this scary account.

At start up "check engine" and "trac off" lights were on. Truck had no acceleration and transmission would not shift. I took the car to the dealership and diagnostic codes p2440 and p2442 were detected. Dealer had to replace the air injection system bank 1 and bank 2. During research, I discovered numerous other owners of 2012 Tacoma's complaing about the same issue. Some even lost power while driving. Also, the tundra apparently had a similar issue being reported.

The contact owns a 2012 Toyota Tacoma. After starting the vehicle, the check engine, traction control, and maintinence indicators remained illuminated. While driving, the vehicle would not accelerate past 25 mph. The vehicle was taken to autonation Toyota in houston, texas where it was diagnosed that the engine air pump and air valve were faulty and needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 45,000.

The contact owns a 2012 Toyota Tacoma. While driving 62 mph, the check engine indicator illuminated and the vehicle began to lose power. The contact stated that the vehicle experienced a limp home setting. The contact stated that he was aes certified. The contact stated that the tow hitch was in use when the failure occurred. The vehicle was taken to a local dealer (fiore Toyota Volkswagen 1000 s. Logan blvd, holidaysburg, PA 16648) where it was diagnosed that the secondary air injection switching valve failed and needed to be replaced. The vehicle was repaired by the contact. The manufacturer was notified of the failure, but did not offer any assistance. The failure mileage was approximately 88,000.

Secondary air injection system (p2442). This hardware defect has been a recall for tundra but not for Tacoma. The part is defective on most 2012 Tacoma and very expensive to replace. There are safety issue as the vehicle unable to accelerate, but only able to limp. There are many discussions about this issue but Toyota has not done anything about this.

Failure of the secondary air injection pump and valve emission system prompted engine to run in a reduced power mode, and this occurred on a on a relatively new vehicle with below average mileage. While setting may protect engine, this created an unsafe driving environment for vehicle within fast moving traffic. My compliant is not related to the reduced driving mode that may have protected the engine, but rather the poor design of the air-pump/valve system that prematurely failed causing the reduced power mode.

As I went from side road to main road, truck would not accelerate to full speed even with foot on the pedal, indicators trac off and check engine were lit. Went to mechanic and error codes p2440 and p2442 indicated malfunction in secondary air injection system. Was told new air pump and diverter valve required at cost of $2k. Truck has less than 30k on it,but is 5 years old. Going into limp mode is dangerous as the main street is 55mph. Toyota states tundras have same issue that is now covered by 10 year/150k warranty, but nothing for Tacoma owners. So I am quite angry with that as well. Have read online that many other owners are having same issues. Toyota should recall these defective pumps and valves in addition to disabling the limp mode as it is very dangerous.

Tl the contact owns a 2012 Toyota Tacoma. While driving approximately 55 mph, the vehicle lost power and then immediately regained power. The check engine warning indicator illuminated. The failure recurred twice. The contact coasted the vehicle to a service station, restarted it, and was able to drive. While depressing the accelerator pedal, the vehicle would not accelerate past 25 mph. The vehicle was taken to Toyota of poway (13631 power rd, poway, CA 92064) where it was diagnosed that the air system valve needed to be replaced. The contact was also informed that the air injection pump may eventually need to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that they would not cover one hundred percent of the repair cost because the vehicle was out of warranty and there was no recall. The contact was referred to NHTSA. The approximate failure mileage was 133,472.

2012 Toyota Tacoma. The vehicle has codes p2440, p2441, p2442 relating to the secondary air injection system (sais) valves being stuck open/closed. This appears to be a common problem with 2012 Tacoma vehicles and several years for tundra vehicles. For the tundra, Toyota instituted a customer support program and extended the warranty coverage for the sais. With the vehicle having only 47,391 miles, it is outrageous that the sais would have issues or failures especially being a Toyota. Since the truck is in limp mode and not safe to drive, it will have to be towed to a dealership. Between this issue and a noise and pulling periodically from the front differential/drivetrain, we are very disappointed in this vehicle.

Secondary air injection valve quit working and put my truck into a 'limp mode. ' during this time my speed was cut no more than 40 m. P. H. I was merging onto the highway at the time and it created a very unsafe condition. I started researching the issue and saw a ton of other people had the exact same issue. I'm sure Toyota knew about it as well, because the mechanic at the dealership did. Why didn't they put out an alert or recall??.

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.
