Horn will not work with the steering wheel centered. If you turn the steering wheel 90% to the left or right the horn has worked sometimes. Toyota issued a recall for this problem on other tacomas but not for the 2012. The toyota dealership is saying that its most likely the clock spring.

Horn will not work with the steering wheel centered. If you turn the steering wheel to the left or right and pushing the horn it will work. Toyota issued a recall for this problem on 2005-2009 tacoma but not for the 2012. Toyota has known that they have a problem with the clock spring that they won't address on the 2012's.

Sun visor , spring inside visor breaks. Making the visor hang down. Wire harness from AC blower motor, so somewhere in the engine compartment overheats and melts wiring so the air conditioning stops working.

Toyota has know that the clock spring has been failing for years. They issued a recall for model years 2005-2009. Trucks in the model years 2010-2012 are also affected. Problems - loss of horn, loss of airbag. Optional if equipped - loss of cruise control and/or loss of radio controls. This is a major safety hazard! Loss or horn and loss of air bags are a very, very dangerous situation!!! The clock spring fails randomly so you might not be aware until it is too late!!!

The check engine light and the trac off light came on as I was merging onto the interstate. I immediately stopped the vehicle, pulled over, and took my 2012 toyota tacoma with 78,000 miles to the mechanic where I left it overnight for them to look at it in the morning. Running a diagnostic they found code p2443 - secondary air injection switching valve stuck. I asked if they had dealt with this before and they said this is a common problem for toyota and they have done recalls on both the tundra and sequoia models that have had these issues, but the tacoma hasn't had a recall yet, even though it seems to be just as common with the same parts. They said the cost of parts and labor would be around $2,000. When I asked them if the vehicle was safe to drive off their lot they said these codes can cause the tacoma to go into "limp mode" where you can loose power, acceleration, and won't be able to go over 45mph. I hate to think what could have happened if I had kept merging onto the interstate and tried to get up to speed only to "limp" into traffic or if this had happened a minute later on the interstate! Every thread I read online from multiple sources show people having similar issues from as low as 1,000 miles on the truck. The issues with the secondary air injection pump and switching valves seems most common between 50,000-80,000 miles, but eventually does happen in the 2012-2015 tocoma models.

Horn quit working, only works when the wheel is turned to the left, fuses are good and so are the relays.

Driving at high way speed; the ABS light, parking brake light, traction light, lost power to windows, A/C, radio, power steering, engine was running rough, then the check engine light came on. Could be a safety issue of control of vehicle for drivers not paying attention. Toyota dealer said the root cause was a bad cell in battery that caused the ign#2 fuse to be blown. These batteries have known issues to be bad from the factory. Reported earlier about 30000 miles the factory battery would not start vehicle and dealer said they replaced because of a bad cell. I own a 2008 toyota tacoma also , same model and make as being reported and that battery has been replaced 2 times for same reason.

My 2012 tacoma has a spiral wire issue that dealer refuses to fix even though this part is associated with the takata recall in previous year models wondering why the recall stopped at 2011 and does not cover the issue with my truck. Currently only affectin the use of my horn but as seen in previous recalls could affect more lthings later on.
