Tl* the contact owns a 2012 toyota tundra. The contact stated that the vehicle was purchased with the check engine warning light illuminated. The vehicle was repaired at john harvey toyota (2901 benton rd, bossier city, la 71111, (318) 741-1337). The contact stated that after the vehicle repaired, the transmission failed and the contact returned the vehicle to the same dealer where the transmission was also repaired. The contact stated that the vehicle failed to accelerate above 25 MPH and was taken to an independent mechanic to be diagnosed. The mechanic determined that the secondary air injection system failed and needed to be repaired. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 115,000.
My tundra with 75,000 miles has a camshaft tower leak and this oil is falling into the exhaust manifold without being noticed because it doesn't make it to the floor, but it gets to the sensors and starts ruining them. Toyota motor co knows about this issue in all their 5.7l engines and that its a factory robot error by not applying enough sealant in the gasket. And this is just being fixed if you are either under factory warranty or extended warranty. The vehicles loose power and if driving on a highway can cause a major accident. The least this company can do is offer a voluntary recall but they are refusing to do so because the fix will cost them $3500-$4000 from all their 5.7l engines assembled in the u.s. So for my safety and the safety of many toyota drivers and general highway drivers safety, I hope this would be taken into consideration. Thank you
'12 toyota tundra appears to go into limp mode, brought it to the dealer ship, a recall was listed for something, didn't fix the issue. Had to have about $1,500of work done. Fixed the issue....for 1.5 months. Back at the dealership again, throwing all the same codes for all the same parts. Clearly the parts being used aren't a fix to the problem, and seems like more than just is are having the same issue. At this point it's playing with peoples lives. Toyota dealt with this with earlier models but anything 2012 and up , nothing is being done. Someone is going to get killed if these trucks go into limp mode on a highway and they get hit at 70-80 miles an hour from something out of the drivers control, that toyota knows about. When will a recall condo this, something needs to be done.
After filling up with gas and pulling onto highway there was no power like truck was in limp mode and tractor trailor had to swerve off of road to prevent severe accident. The secondary air injection has a severe mal function which toyota only recognized in earlier models and they extended warranty to 10 year and 150,000 miles. This is a severe problem I wish someone would investigate before it's too late and lives are lost. There is not much response time to make a quick decision during this moment. Thank you
Leaky tundra cam tower seal. Toyota claims that they uses a epoxy type seal that has been found to leak, and needed to be replaced with different type of gasket seal..the charge for this approximately $ 5000.00 that they say is the consumers responsibility.
Check engine light went on. Got a code p0418-vehicle will go limp/not able to go over 25mps. Toyota has a warranty repair program in place for all 2012 tundras with a 5.7 size but not mine because it is a 4.6 even though it is the exact same problem!!!
My 2012 tundra with 107k displayed the check engine, 4lo, and traction control warning lights and would only drive in 'limp mode'. Luckily this happened at startup when I was leaving work one afternoon, and not as I was driving at highway speed. I 'limped' to the local dealer using back roads and left the truck for diagnosis. I was notified that the truck was exhibiting code 'p2440' for a faulty secondary air injection system valve, and that both secondary air pumps and valves would need to be replaced to correct the issue. The repair would cost $2500, but "luckily" the dealer had the parts in stock because this was a common problem. Since I needed the truck to get back and forth to work each day, and I am not ready to replace it, I authorized the repair and picked it up the next day. Subsequent research on-line showed that this has been a known issue for years. Toyota extended the warranty on these parts for my 2007-2011, and later for certain 2012 vehicles as well. Unfortunately, it appears that only the 2012s with the 5.7l engine are covered (mine is a 4.6l). From my research, it seems that the pumps/valves in my truck are the exact same parts that are known to fail (and are covered) in other model years. I called toyota customer service, and of course they advised that they would 'log' the issue and contact me should the warranty be extended to cover my truck. Judging by the number of complaints here, I feel that it warrants an investigation and perhaps applying some 'external' pressure to persuade toyota to do the right thing and cover all of the affected vehicles. Not only is this an emissions issue, but could be a serious safety issue if the truck were to go into limp mode while driving.
On numerous occasions while driving, my 2012 toyota tundra suddenly lost acceleration power and experienced the engine failure known as "fail-safe" or "limp-home" mode. As evidenced by toyota t-sb-0160-11, warranty policy bulletins, and warranty enhancement programs, toyota is well aware of this serious design flaw and safety issue, yet has chosen to repair or compensate only a select few. The parts that had to be replaced after my vehicle repeatedly went into 'fail-safe / limp-home' mode correspond directly with the part numbers referenced in toyota warranty policy bulletin pol17-02 which covers this defect in other models, but not in my 2012 model. My out-of-pocket cost to repair this manufacturer's defect was $3034.87. This a known air injection system water intrusion defect and common safety complaint at the federal safety agency and on multiple toyota forums, affecting numerous 2012 tundra's which toyota is refusing to acknowledge and compensate for. I have written several letters to both the ceo of toyota and the toyota customer experience center requesting reimbursement of my repair costs and have been denied twice; the first denial in writing, the second denial via telephone. I request the federal safety agency investigate this serious safety issue to protect the lives of others driving these dangerous vehicles. Toyota has an ethical and safety obligation to the consumer to remedy this defect and to compensate those of us who have had to bear the financial burden of their failure to correct this well-known issue.
2012 tundra 4.6 v8 my truck will go into limp mode and the 4lo light flashes, check engine, and trac off lights were all on. Almost complete lose of power will happen. In traffic I end up blocking ever vehicle behind me, because the truck will not reach the speed limit. If there is a hill then the truck barely moves going up the hill. After looking online I saw it's a pretty common problem on toyota with the secondary air injection pump seizing. I checked it with the code reader at a local shop and the guy confirmed it, code p2240 "air injection switching valve stuck open bank 1." he told me he used to work for toyota and knew there was the extended repair on this issue but couldn't recall the specifics. I went into toyota and unfortunately they will not cover it for my truck after they ran my VIN number. It seems like a lot of tundras with the 5.7l motor are covered but the 4.6l motors are not. I was informed by toyota that in the future it might be covered.
I have noticed an oil leak from the camshaft housing on my passenger side. This has LED to oil burning on my exhaust manifold which is a fire hazard.
With only 81,719 miles on my truck I had to have the air injection pump & valves replaced on 3/29/2019. I was informed that this was a common problem which had been recalled in the 2011 & 2010 models. If a recall is made within a year of the part being replaced I will be reimbursed. I work from home and the truck has only been driven for leisure or chores for the past 3 years. It was driven daily in las vegas from 2015-2017 and in orlando from 2012-2015. There have been no other engine problems. In january of 2019 the check engine light came on and the car was performing with less power but everything worked okay. Instead of driving an 8 cylinder truck it felt like driving a full size truck with only 4 cylinders. The issue happened overnight. Everything was fine and then the performance just went south. I waited 2 months to have it looked at because I rarely drive and because it still ran but with less power. I was told by toyota that if another mechanic fixed the problem and a recall came later then I would not be reimbursed. After I was informed that this would more than likely become a recall I moved forward with using toyota's service department. My goal is to find out if there is a recall pending for the 2012 tundra air injection system or at least find out if the problem is widespread. If I was taken advantage of by a dealership using the recall as a tactic to get my business I want to make sure to let others know so I hope someone from the federal safety agency will follow up.

I took my tundra in for a oil change and the dealer ship said I have oil leak at the timing belt. It would be over 1600.00 to fix this. It is time consuming for the labor rate is high. The truck only has 45,000 miles on it.
My truck has been having hard start issues since winter 2017. I figured it was my battery so I replaced it, but it didnt help. The hard start wasn't consistent so I chose take some time to see if any other problems surfaced. Got through winter 2018 and spring/summer 2019 with it still starting rough on occasion. By october 2019 my truck reached approx 78k miles, and one day it didn't start at all. Took three tries to get it going. I had the battery checked once again. It tested bad but it was under warranty so I had I lt swapped out. The problem persisted. This time it gave me an engine light. Mechanic said it was an 'evap code' and recommended I replace the gas cap to start. Code didnt return but still hard starting. Took almost two months and engine light came back on. This time p1604 startability malfunction. Was told I had to take it to toyota to get a reflash. I decided to do some research and came across the problems tundra owners were having with this ffv density sensor malfunction. Printed the old service bulletins and went to toyota to talk to service dept about it. They said toyota just put out a new service bulletin in december 2019 for the reflash but now also replacing the fuel pump (toyota told me density sensor attached to the pump). Unfortunately toyota also told me they won't cover the cost since my truck had just gone over 80k miles, and they are not flexible with that at all, even though I told them it started before 80k. T-sb-0166-19. So I got prices. The reflash is about $140 and just the cost of the pump itself is $600, not including labor. I have spoken to the toyota USA customer care team and they said they cant help me since I didnt take it to the dealer to diagnose it. Apparently it doesnt matter if you have service records from another shop. This is my 3rd toyota, and I love my truck so this breaks my heart.
When driving my check engine and "trac off" light comes on and the engineer will not accelerate above thirty miles an hours. If you disconnect the battery and reset the computer it will work for about three mile then the check engine and "trac off" light comes on. This is the same indication earlier tundra models have with secondary air injectors recall. An it is widely documented online as a problem for 2012 tundra's. Yet toyota continues to denies it's a problem and is not covered under the recall.
Driving in highway traffic and engine reduces power significantly causing the vehicle to rapidly slow down and become a hazard in traffic. Took it to dealership and they said the secondary air injection system needs to be replaced for $3300. This is a known defect for the previous model year. I contacted toyota hq and they refused to cover repairs for this know design defect.
* ongoing manufacture defect / safety concern with 2012 toyota tundra 4.6. Code p2440, secondary air injection. Bank one open.---check engine / trac off lights / engine in "limp mode" * documented recurring incidents on 4-2-19 and again on 10-12-19 after costly out of pocket repair. * my 2012 toyota tundra 4.6 motor double cab has experienced the air injection pump failure twice in a six month period. This failure is a safety hazard leading to loss of power and vehicle control. The first occurrence was after a 2,000 mile trip. Driving downhill the dash lights (check engine / trac off) came at highway speed and immediately vehicle power reduced as we tried to power up the next hill. We were able to avoid being run over by following vehicles by pulling off the road, and limped to the nearest mechanic shop. Contacted 3 dealers and toyota corporate with no positive outcome. All parties acknowledge the ongoing defect but will not pay or offer a solution to end the problem. Paid out of pocket for expensive repair. The 2nd occurrence six months later found us again unable to reach or maintain safe highway speeds. Avoid dangerous highway situations, or ability to climb hills. Both instances occurred without warning. * this emission control defect that toyota has known about since the 2007 models. They even extended the warranty through the 2011 model year. Toyota also claims the problem is neither drive-train nor emissions related. After many attempts at the dealer and corporate level, toyota refuses to extend repairs for this well documented defect beyond the 2011 model. Toyota suggests that when enough complaints are recorded, they will extend the warranty on newer models. The lack of support from dealers and corporate toyota is alarming. The repair out of pocket is expensive (from $500 for a temporary repair to $4000 for a replacement from the dealer.)
When cranking the vehicle all of a sudden as of 5 days ago the check engine light appears along with 'track off' indicator. This throws the truck in 'limp' mode decreasing the power of the vehicle by 50%. This happened the first morning and I was entering a on ramp to get on the high from my neighbor and almost got plowed over due to not being able to properly accelerate to highway speeds while entering the ramp. I had a technician check the issue and was told it has to due with the 'secondary air injection valve' failing. After about four days of research I found this is a common problem it not just my vehicle but multiple years and motor sizes. Toyota apparently covered certain year models/vine but when calling regarding mine they said my vehicle wasn't covered evening though there are thousand of consumers having the exact same issue. This issue is also an expensive repairs cost upwards to $3,500-$400 to fix. Toyota is aware of the problem and apparently doesn't care that it also cause safety issues with the vehicle not having proper power to operate. This is a manufacturing defect plan and simple.
This complaint is the same as many I see here and across the internet. Driving on the washington dc beltway and my 2012 tundra goes into limp mode which reduced my power significantly causing a unsafe situation to say the least.. Dealer said problem was with secondary air injection system and the repair was very expensive. Now 12 months later the truck is having the same problems. This is an inferior system that toyota should stand behind and cover all the costs associated with fixing instead of charging tundra owners after they've already spent hard earned money on the vehicle purchase. This is a wide spread problem that toyota is not owning up to.
I was coming off an entrance ramp merging into traffic on to a 4 lane highway when my check engine light, trac off light and blinking 4 loe came on. The engine went into limp mode greatly reducing my power and it felt like my steering control got loose. I had to pull off the road to keep from being run over by faster traffic. I was able to make it to the next off ramp and get to a mechanics shop. They hooked up a analysis computer and came back with maintenance code p2432, secondary air pumps and secondary air pump valves. Upon further research of this issue I have found out that this has been an ongoing issue with toyota tundras going back to 2007 models. The warranty has been extended on 2007 - 2010 models but not newer models which are still experiencing the same problem. My vehicle is considered low mileage for a 2012 with only 79,786 miles. I feel this problem constitutes a potentially dangerous safety hazard due to the drastic reduction in power which could cause an accident depending on when the parts in question fail.
Secondary air injection pump and secondary air injection switching value causing check engine and trac control lights to come on. I was told by the dealer that the same piece and design was recalled on the 2011 but not the 2012 tundra. It comes on and off but when it is on it feels like that there is a limp mode making it difficult to get up to speed on the highway. The steering feels different which I think is the traction control.
Secondary air pump and control valves failing and this is a on going issue with these trucks almost $3000 to fix
P0418 secondary air injector relay a malfunction. Check engine light is on
I was pulling out of work. You must cross 3 lanes of traffic plus the center median to turn left. This is a city street. Speed limit is 45 I believe with many vehicles going faster. Vehicle had the smog air injection pumps and valves fail. This cuts power drastically to the engine and puts it into limp mode. I was forced to swerve back into and stay in the center median instead of merge into traffic as the vehicle had little power. I was able to wait for a bigger gap in traffic and limp the vehicle to the repair shop. I believe this could be deadly should it occur if trying to get on the freeway or pulling a trailer and the engine cuts power drastically. Toyota has a long history of issues with these parts failing going back to 2007 and possibly earlier. There is no need for a smog pump failure that only runs for 2 minutes on cold start to drasically cut engine power and endanger the driver and other motorists.
While driving, multiple dashboard lights came on and my truck went into "limp mode," meaning I lost almost all power while driving in heavy traffic. Turns out this is an issue with the air injection pump, which is a known problem in toyota tundras. I believe this is a safety issue that toyota needs to address.
I own a 2012 tundra with the 4.6 liter v8 engine. Very very similar or exact to other complaints on this board. Truck went into limp mode while on the highway. Took the vehicle to the dealership and had to pay to have them replace the secondary air injection pumps and valves. I agree the fix needs to be extended to all year models and engine size tundras, not just up to 2011. Also agree that these defects could result in a fatal situation if not corrected across the board. Toyota should also reimburse those that have had to pay for the repair.
I had a sudden jump in my rpms and accelerator malfunction I had to carefully guide the truck to the side of the road. After it died I could not start it. The engine light flashing, the 4lo flashing and traction's all flashing. I still had electrical but no power. I was being followed by another vehicle who almost hit me and my daughter. These trucks are supposed to be know for their life span and safety. This is not what I call safe by any means.
I have a 2012 tundra with 135k and 4.6 liter. I also see several other complaints here with my same problem. My experience is that after sudden jump in my rpms from 2 to 4 and accelerator malfunctioning, I carefully and very slowly drove my truck to the dealership this morning due. I had slow/no acceleration, check engine light on and traction off. In last couple of months, have had to pull over turn it off and back on for it to go again once before. I agree that the fix needs to be extended to all year models and engine size tundras, not just up to 2011. Also agree that these defects could result in a fatal situation if not corrected across the board.
Truck went into limp mode because of secondary air injection valve and air pump due to stuck valve. The exact same parts that toyota has extended the warranty on for 2007 thru 2011 4.6 and 5.7 v-8's. Do they wait on the. 2012 models so most will go past the 150,000 mile extension. Very disappointed since I bought this truck 3 months ago. And now they want $2800 for a 4 hour job and about $600 in parts
Tl* the contact owns a 2012 toyota tundra. While merging into traffic at a low speed, the vehicle went into limp mode and had to be turned off and restarted. The failure occurred multiple times. The vehicle was taken to germain toyota of naples (13315 tamiami trail n, naples, fl 34110, (888) 722-4942) where it was diagnosed that the air pump assembly and valve shaft needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 119,000.
