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.

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.

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…

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…

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…

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…

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…

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…

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

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.

Please refer to tsb 0160-11. Toyota recognized that inferior quality parts were used as part of their emissions system and wrote this tsb as a remedy. The problem i have is that they continued to use the faulty parts beyond the 2011 model year cut-off in this tsb. My truck is throwing the same engine and emissions codes associated with this tsb. It also forces the engine into a "low power mode" greatly reducing the…

Check engine light and trac control lights came on around 72,000 miles. Truck started to be sluggish and lose power. The truck is in a constant 'limp' mode and fails to properly accelerate. It is definitely a safety issue as it causes unsafe conditions when trying to accelerate into a traffic lane. Took it to dealer and it is an issue with the secondary air injection valves and pumps. Dealer quoted me $2184.25 to…

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…
