Horn siren is not being activated when pressed by center switch on steering wheel. After researching many tundra message boards, this appears to be a frequent problem amongst tundra owners. Incident: vehicle in front of me at drivethru backed into me when they thought they were in drive after repositioning themselves for mic. I was not able to beep my horn and warn them. Luckily no damage occurred.

On 11/25/22 I meet with American Auto Mall to buy a used truck I was assured through text, website and window sticker that the truck was in excellent condition inside and out.. I have all this documents proofing this.. I did van limited inspection at the lot and a test drive.. found nothing that stuck out.. other than the radio not working but the dealership said he would reimburse me if I got it fixed..so after that a down payment was made of $5550 dollars and paperwork was signed.. I drove the truck home and the next week I got in it and it wouldn't start, turns out it needed a battery and alternator, so I took it to a shop and was told that this vehicle was badly rusted and had a lot of hidden rust damage.. and improperly installed brakes., coolant leaks and exhaust leaks.. after finding this out I tried to call the dealership and he hasn't been replying.. …
Horn stopped working right after I bought this truck from a dealer. I did some research on why it stopped. I was told and also read that it was the air bag clock spring. This controls the air bags and horn and other components. What it is the clock spring was installed by Toyota that had a bad spot on it. This causes the wiring harness to start rubbing and cutting into the wires. Would cause the horn to stop working and the air bags not to work and other things that is wired to this harness also. This should be a safety concern, and Toyota needs to recall to fix. Read that the 2011 Toyota's was bad for doing this. Costing the customer about $800.00 to fix. I have the truck about 3 months. Might be the reason it was traded in. Works some times and doesn't work. I am worried the air bags will deploy if not fixed. Please check into this. …
My 2011 Toyota Tundra has experienced issues with the internal climate control system from day 1 of purchase. I have discussed this with Toyota and have had in for service at least 5 times. The recirculation button (which is electronic, not manual) will automatically switch off while driving every three (3) minutes and allow outside air to flow in. While quite annoying at times, it is especially dangerous when I visit my cabin in julian california in the winter, and the switch to outside air blows in the outside 20 degree f weather, while driving 20 miles down a very dark (no lighting) and very curving road populated by many deer. My attention is focused on the center climate center, and not the road ahead. Toyota has given me many explanations, several which were incorrect, and now they just concede that it's working exactly as designed. …
The Tundra is kept in our garage and is driven one or two times a week. On christmas day 2014, when I drove the Tundra, I noticed a number of unusual lights flashing on the dash, including the check engine light. When I examined the engine, I found a rats nest on top, and I suspected a rodent had damaged the wires. I took the Tundra to the local Toyota dealer, and the service representative told me that the insulation on the wires of my Tundra contains soy which is attractive to rodents. It turns out that 7 wires needed to be overlaid at a cost of $760. It seems to me that putting soy in the insulation around electrical wires is a design flaw that could lead to rodent-caused damage that could lead to safety problems. I did some google research, and it appears that this flaw has been known since at least 2011, and was described in an article in motor age magazine. …

I bought my Tundra with 7 miles on it so I know its not neglect that causes this problem it's poor quality part ..the clock spring under the steering wheel is malfunctioning my horn doesn't work it only has 60K on it I've been a loyal Toyota technician as well as ii\ owned a few I called the hotline (Toyota)theirs nothing they could do for me I will not recommend Toyota to my customers any longer poor quality parts cost the consumer not the dealer its a shame the once mighty Toyota corp has become just like the American counterparts
I was headed to springfield on I-95 and a car was coming into my lane and I tried to blow the horn and there was nothing. I ended up swerving into the left lane with traffic coming. It's happen a few times. I checked my fuse and it was fine. I ended up having to replace the air bag clock spring. It was a close call for a pile up situation let me tell you. $365.33 to have the air bag clock spring replaced. That should of never happen.
