general problems of the 2012 Toyota Tundra

Product almost set my car on fire, luckily I was stop at a car wash when one the cleaning crew members noticed smoke coming out from under my hood my hood , I opened the hood and the actual light bulb was on fire, it burnt my original hardness of my vehicle and the housing of my head light.

2012 Tundra faced a lot of problems like air injection pump failures, sticking of secondary air pumps, knock, along with other issues like speed control, engine cooling, and throttle failure. At present, it has been slapped with 136 complaints, 4 recalls, and 1 investigation as recorded on NHTSA site. Sep 2, 2022.

My horn stopped working. I have two new drivers and this is a huge safety concern of mine. The dealer is telling me that this is a $800 job. Online I'm finding that this is a very common issue that is occurring . . . Effecting the safety or our vehicle.

Started my truck and the 4lo, check engine and trac off lights came on. The 4lo was blinking.

The horn can not be operated by the steering wheel. The horn still works when the panic alarm is pressed. According to several forums that I have visited, it’s a common issue with the steering column rubbing the insulation off of the wire. I believe that if this is that common of an issue, it should be reported, and hope that it will be addressed by a recall.

The horn no longer works on the vehicle. I can no longer alert drivers who do not see me while driving or in parking lots. My auto shop confirmed the horn did not work and estimated the repair. There were no warnings.

When in motion the vehicle enters limp mode and loses power. Acceleration by pedal does not function, the engine only revs and does not speed up. The vehicle slows down to anywhere from 25 to 5 miles per hour on its own without stepping on the brake and the transmission doesn't shift. This happens anywhere, highway, street, driving straight, turning, etc. No warning. I almost got rear ended because this problem equates to someone driving on the highway and slamming on their brakes with no brake lights!! I could have lost my life today! Toyota is aware and has been aware since 2007 of the problem and is playing with peoples lives!!.

A light came on and it started losing power. Took it to the shop and was told it was bad gas. I put the cleaner in it and it didn't fix it. I had some buddies tell me to unplug my battery because it sounded like a safety feature. So I did. The light went off and the truck acted right for a few miles then started doing the same thing. Vehicle was in motion on the highway. My buddies referred to it as a "limp mode" or something like that. I was afraid to have it worked on because I was told if there was a recall the manufacturer wouldn't be liable.

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.

Secondary air pump and control valves failing and this is a on going issue with these trucks almost $3000 to fix.

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 ability to accelerate. Lastly, it turns off traction control which affects the stability of the truck. I have filed a ticket with Toyota and from what I have read on the internet, I don't expect much help. The parts to repair this run over $1,000 alone. There are many owners having the same issue with the Tundra, sequoia and some other models (on the 4. 6l, 4. 7l and 5. 7l engines). The engine codes usually appear on startup (when the emissions device are supposed to kick in), but the low power mode kicks in while moving.

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.

I traded my 2012 Toyota Tundra for $17,000. 00. Blue book 'trade-in' value was approximately $20,000. 00 - $21,000. 00 at the time. My truck had low mileage and was in excellent condition, except for the undercarriage rust. I lost $3,000. 00 - $4,000. 00 in the trade-in.

The horn stopped working.

Mirror control on instrument PA nel has no lights. Had to turn on cab lights to see the mirror controls.

As I was driving, another vehicle started veering into my lane. I pressed the horn pad to warn them. However, because I used my right hand and hit the pad at the most natural location for me -- I. E. The lower right portion, instead of honking the horn I hit the hands free talk switch on the steering hub. This has happened more than once. This is a natural location to hit the horn pad and other people I have talked to have had the same problem. In my view this is an unsafe situation because, not only do you not warn the other vehicle but you also get distracted at a time of possible extremis. It is bad design and need to be corrected;.

Electrical buzzing noise from dash area when pressing gas pedal. Dealer says not a warranty item. After researching online many people experience same issue with several Toyota models.

After only a few months of owning the truck almost every morning when I try to start the truck it took at least 2 cranking cycles to start. It's been a on going thing and now the throttle acts up when I first pull out of the driveway. It doesn't give any code and the dealership can't figure it out. The truck now has 36322 miles on it.
