June 1st 2021 I went to park in a parking space at a local mall. My truck instead of stopping it accelerated out of control jumped two stone curbs, drove though a fence and landed into a swamp. Call Toyota and they have opened a new case # 210602000065. Police report # 21-374-AC. This isn't the first time that this has happen with this truck. It happen in Aug 2019. I contacted Toyota case number 1908060035. They sent out EAA Engineering Analysis Ass. out who did a ACM.CDRX file a month later. Toyota came back said they couldn't find anything wrong and my case was closed. Another incident in winter of 2016 where my truck was stopped and it accelerated on its own and It drove in the 4 way intersection where it caused an accident. lots of damage to cars. Toyota was contacted and they sent me to a dealer for repairs.

During normal driving, the check engine light and traction control off light came on and truck immediately went in to limp-home mode. I had it scanned for codes at the local auto parts store and it came back with p2440 and p2442 which seems like a common issue with a valve in the secondary air injection system. I quick google search showed that some 2012 tacoma owners are getting this covered under a special warranty extension, so I puttered over to the toyota dealership expecting to hear the same story, but they are telling me the ECM computer is bad. Which I am trying to get clarification on since I can't find any ECM failure issues for this make and model year.

Tl* the contact owns a 2012 toyota tacoma. While driving approximately 55 MPH, the vehicle lost power and then immediately regained power. The check engine warning indicator illuminated. The failure recurred twice. The contact coasted the vehicle to a service station, restarted it, and was able to drive. While depressing the accelerator pedal, the vehicle would not accelerate past 25 MPH. The vehicle was taken to toyota of poway (13631 power rd, poway, ca 92064) where it was diagnosed that the air system valve needed to be replaced. The contact was also informed that the air injection pump may eventually need to be replaced. The vehicle was repaired. The manufacturer was notified of the failure and the contact was referred to the federal safety agency. The approximate failure mileage was 133,472.

Almost lost control of vehicle when the trucks performance jumped into limp mode "trac off" as I was driving. Loss of speed and performance caused me to be a driving hazard. 2 vendors today found the codes p2440 and p2442, which appear to have triggered my truck into "trac off" and "check engine" light on. Mode causes my truck to only drive about 45 significantly impacts performance and dangerous to drive. This is a safety hazard,I had no warning that the loss of performance was going to happen initially when I was traveling.there is another problem that appears to be on a larger scale.I have briefly scanned the internet in the last hour and spoke with various vendors about the problem & I have called my dealership & even the main toyota line and everyone is aware of the issue. The codes are p2440 & p2442. After finding out the codes I looked at the air injection pump & I was astonished to see that the pump was completely full of what, like someone literally took a waterhose & filled it up. Logically, this is why the air injection switching valves 1 and 2 are both stuck open one code for each of the valves. The next thing that is unusual is that there are an incredible amount of people having this same problem but no recall..then I found the tundra recall for the exact same pump issue! It is peculiar, that a different model truck with the same pump has this problem & no recall or remedy. Fact-tundra is a more expensive truck than tacoma, is toyota fixing public relation issues for those more well off because they know how to complain to the right folks or cause a big stir and they will hold off on pulling the trigger on a "warranty fix or recall" on the working mans tacoma? This is just an opinion but my intuition tells me this is intentional. The fix is approx $2000 I am stuck driving 45 MPH till then with shady steering & performance. #accountability #me too

While commuting to work the engine light and traction control light came on, causing my truck to slow down, very slow. It would not let me accelerate and disabled my progress to around 2000 rpms. This could have been a very serious or a dangerous situation especially if I was towing a load or in a major traffic situation. Codes - 2440 and 2442 were the causes of this scary account.

Code p2440 and p2442. Air injection system valves are stuck open (related to emissions control unit) which causes the vehicle to go into 'limp' mode abrupbtly. This renders the vehicle undriveable, and can occur in the midst of driving causing serious danger to the driver and fellow drivers on the road. Toyota is unwilling to cover under any powertrain or emissions warranty. This issue is pervasive among 2012 tacoma owners and toyota redesigned the system as early as 2013 which implicates their knowledge of such a defect.
