Truck was in Toyota shop in Vermont for stalling of vehicle. Thought it was fuel pump due to recent recall - specifically asked if it could be that and was told no. They found mice nest in intake manifold, knock sensor was found to be chewed, and replaced. Once I received my vehicle, it continued to do the same thing after 2 days. Upon looking under the hood, found that the air intake filter was left off. I fixed that, and then the same issue starting occurring again. Had to have my vehicle towed to different shop (to trusted mechanic) they have found after replacing the battery and a mass air flow sensor, that it is truly in fact the fuel pump. They tested fuel pump and it's only putting out 20psi instead of 40. I called Toyota, but they are claiming that only the newer Toyota are affected, but on the recall list it goes back to 2013 in different models. This seems similar to the issue Subaru was having with their air bags. My Toyota dealership, should not just be assuming that this couldn't be correlated with faulty fuel pump. My vehicles symptoms are the same as what the recall has stated happens. Before denying me anything, they should be willing to at least investigate and look at my vehicle. It's also suspicious to me that my vehicle started doing this about 2 weeks prior to a huge safety recall coming out in regards to fuel pumps.

Toyota has a known problem with their 5.7 L V8 engine with the cam shaft towers leaking oil onto the exhaust which is a fire hazard. This is a result of them not applying enough sealant at the factory, which was confirmed to me by the Toyota dealership. Toyota refuses to cover the issues even though thousands of people are complaining about the issue online, class action suits have been opened and there is a petition online to get them to recall this issue with over 6,000 signatures. Mine personally has the oil leak and I can smell burning oil every time I get out of the vehicle. There is a large oil burn stain on the exhaust where the oil is falling. Apparently it's going to take a fire and someone to get hurt before Toyota recognizes this issue and fixes it.

The Toyota 5.7L V8 engine found in Toyota Tundra, sequoias, siennas, land cruisers, and Lexus lx570S suffer from cam shaft tower leakage, and it will most likely happen to anyone that owns one. It can happen anywhere from 1K miles to 100K miles, but it can damage the engine and other important parts and therefore should be recalled. It is also a safety issue, as it leaks in to the exhaust and could cause a fire. I own a 2014 Tundra that has this issue and the dealer wants me to pay $3K to fix it!

Notice strong smell of oil in the cab, my kids complained about it so, I decided to go underneath and check what's going on and there is a oil leak on the drivers side coming from the engine, my vehicle has only 40K miles and I researched and find out a lot of reports about this issue. I'm afraid the oil dripping on the catalytic converter will catch on fire, not to mention the smell and carbon monoxide that we are breathing inside the cab. Especially my kids.

I purchased a 2014 Toyota Tundra on 02/04/14. I had driven the truck approximately 4 times and on 02/10/14, with 236 miles, I started the truck to go to work. I went back in my house, as the temperature was around 0 degrees Fahrenheit and allowed the truck to run for several minutes. I returned to my truck and left for work. After driving for several miles, the check engine light came on and the truck entered "limp mode." I was not far from work so I continued to work, driving at a max speed of 40 mph. I contacted the dealer and advised them of the problem. The truck was subsequently towed back to the dealer. On 2/12/14 I picked the truck up from the dealer. I was told it was an aip (air injection pump) failure. I was also told there is no fix, and the problem could happen again in cold climate. After several phone calls to Toyota customer care, I got nowhere. I was told there is a fix in the works, but for now I am left with a truck that may go into limp mode when it is cold out. Living in the North eastern United States, it is cold here from October to mid-March. If this truck were to suddenly enter limp mode when I am attempting to ascend a hill, this could present a safety issue to myself and other motorists, as I would severely be impeding the safe flow of traffic, going 10 mph uphill, without so much as a warning. I feel the sudden reduction in power could greatly reduce the operators ability to safely operate the truck, especial when negotiating traffic. It is extremely disheartening to me to knowing that I bought a $39,000 truck, touted as being among the most reliable and dependable, that may or may not run when the temperature falls..and after speaking with Toyota, they know it is a problem..
