The fuel pump failed on my Tundra. Several dashboard check engine lights suddenly lit up to warn me of the issue. While I was able to safely get it to a mechanic to repair the independent Toyota certified mechanic I use shared they have seen a volume of these where the car stops immediately with the Fuel pump failing completely. I was lucky as the day prior to this I was driving through mountain passes on the highway in Colorado. I have since found out from the feedback from my mechanic that they have repaired a volume of these, and it is a known issue by Toyota who issued a technical service bulletin. The fuel pump needs to be replaced with a different specification - the original pump is not sufficient. My concern is putting driver/passenger safety at risk with a complete fuel pump failure while driving. I consider this a near-miss for me, and would worry about others that are about to have this issue.

The trac off light and check engine light cans on at the same time. I took it to Toyota and they said there was an extended warranty of 10 years of 150,000 miles.

It cost over $2,000 to replace badly designed system.

2012 Toyota Tundra 4.6 L at 101,000 miles went into limp mode causing a lack of power and acceleration during city driving which could have resulted in a rear end collision. Was able to limp vehicle to nearby Toyota dealer who diagnosed that the secondary air injection system was faulty. Cost to repair was more than I wanted to pay beingthat I had just purchased the truck within the past month or so. Toyota did not cover the repair so a bypass kit was installed at my expense to get the truck back under power. Contacted Toyota and they advised that the system was not covered however it should be noted that on 2010 models and others the warranty on the system was extended to 150,000 but not on the 2012 4.6L engines that have the same problems as the others.

Check engine and traction light came on. 4lo sign flashed. Vehicle goes into limp mode, slowing down, and at times creeping along while the vehicle was in motion on the highway. There is a large decrease in performance especially going up any sort of incline. Took it to the Toyota dealership for evaluation. They recommended replacement of the fuel pump and was told Toyota is aware of this problem and this make/model is not part of the recall at this time. I called the Toyota hotline, and the worker verified she could see info on the recall talking about warning signs -but they were not specific. She forwarded on my information to another individual. That individual called today, and she advised my warranty was over and my vehicle was not included in the recall.

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.

My 2012 Tundra has just under 70,000 miles on it and the trac light and engine light came on yesterday. Had it looked at and the mechanic says the problem is with the secondary air pump and it is a known problem. Called the dealer and they knew of the problem and told me there is a csp that covers certain 2012 Tundra's. unfortunately the csp only covers the 5.7 L. engines and not my 4.6L model. My mechanic says that everything is the exact same set up as far as the secondary air pump, it's just a different size engine. Not sure why one is covered but the other isn't but I'll have to suck it up and pay the price. Maybe if more people make Toyota aware of this they will eventually cover it. I'm a Toyota fan and have been driving them for 40 years and this won't push me away but it is disappointing.

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.

Monday, January 15th I drove at 65 mph to work at and home on the freeway with no problems. Tuesday and Wednesday the truck was stationary due to cold weather conditions in houston, Texas. Thursday morning the 18th, I drove at 65 mph to work via freeway with no problems. After lunch I drove at 45 mph back to work on a street and noticed the check engine and traction light came on and simultaneously the truck then starting driving extremely sluggish and and far below the speed limit obstructing the flow of traffic. I carefully got over and drove the truck only allowed at 30 mph back to the office. After carefully driving home via street at the end of the day I got home and removed the negative wire from battery and re-connected it to see if this would resolve the issue. After doing so, the results were the lights in the dash were now off and the truck drove proper with no hindrance. This would last until Wednesday 24th. Both lights came back on and the truck started again driving sluggishly. Its seem that when the light is off the truck drives fine, but when it is triggered the truck is drives extremely sluggish. Could the be a defective part? any help would be useful.

I experienced an extreme power loss which made it very dangerous to drive. When bringing to the dealership they informed me that the secondary air intake system needed to be replaced at a cost of $4,000. Upon researching I found that this problem has occurred on similar vehicles dating back to 2007. A recall and replacement was issued for all effected vehicles from 2007-2010. It appears that the problem continues after that date but not enough customers have complained or experienced the problem yet.
