general problems of the 2012 Toyota Tacoma

Defective clock spring. Open circuit.

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.

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.

Secondary air injection valve stuck codes p2440,p2442. Truck goes into limp mode and you can only go a max of 40 mph. Toyota knows about these issues and does nothing about it.

Secondary air injection valve stuck open causing limp mode. Happened near very dangerous intersection and lost all power in truck. As others have stated, truck only has 50k miles and required a $500+ repair (part only) for a component of the emission system which is only used on startup and includes a warranty of only 2 years.

The secondary air injection systems seems to fail quite frequently on these 2012 Tacomas with little to no help from Toyota to take care of this issue as a recall. These are known to fail right after your out of warranty and to charge it's loyal customers over $1000 for a part that should not fail or a part that should be covered is absurd. I have been a loyal Toyota customer my whole life but the issues of the Tacoma are making me rethink my decisions as an automotive consumer.

Driving my Toyota Tacoma, I was approaching a steep decline. I tapped on the brakes and continued driving at approximately 27 mph when I down shifted to accommodate for the snowy road. As I was down shifting the truck lost control and slid sideways causing the front passenger side to hit a snow bank. Once the truck struck the snow bank it flopped over on its driver side. The side air bags on both sides came out but did not inflate. The driver side bags were torn. I found evidence of this with shredded pieces of the air bag found in the vehicle. Additionally the driver side front air bags never deployed.

Fuel system can be heard hours after the truck is parked, few times a week and sometimes daily . And runs 2 to 15 minutes. Contacted dealer and says it normal for fuel evap to do a system check. Ongoing started before 3000 miles.
