The check engine light and the trac off light came on as i was merging onto the interstate.

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…

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.

When i was leaving work the other night my 2012 tacoma went into limp mode and presented the cel and trac off lights on the dash. After reviewing the many blogs on the subject and taking the vehicle to the mechanics, i have found out that the secondary air valve is likely stuck in the open position. The mechanic has quoted me a price of $1,142 ($780 for the part) to replace the whole system (valve not sold…

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.

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.

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…

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 flipped over on its driver side. The side air bags on both sides came out but…

Horn stopped working a couple of years ago. My research showed it was same problem with 2010 tacoma's,and they were recalled! Read there was a recall to replace a defective spiral cable in steering wheel. Called toyota was told to take to dealer, but would have to pay,and maybe be reimbursed. Don't have the money been unemployed for 4 years.
