“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. Dealership has records of my truck coming in since I owned it with complaints of Truck not moving at all to all of sudden to acceleration on its own.”

“Vehicle: 2012 Toyota Tacoma VIN: [XXX] Toyota Special Service Campaign 20TC01 was performed on September 19, 2024, at approximately 103,417 miles. The campaign addressed the secondary air injection system, including the air injection pump and air switching valves. According to Toyota's repair records, the dealer installed an air switching valve kit, air pump repair kit, and air pump cover under campaign SSC 20TC01. On XXX, at approximately 111,187 miles, the same Toyota dealership diagnosed failure of the air pump and air switching valves and estimated $3,664.13 for repair. The recurrence occurred after only about 7,770 miles and less than two years after completion of Toyota's campaign repair. I am concerned that the campaign remedy did not provide a lasting correction of the condition affecting the air injection system. Toyota has declined assistance despite the failure involving the same system that was the subject of SSC 20TC01.”

“My leaf spring(s) is noisy/loosened and to the best of my limited knowledge is at risk for breaking off and puncturing the fuel tank per repair shops. This issue is not covered under Safety Recall E02 (E12) by Toyota for the model year 2012 Tacoma. As a consumer, I don't understand the determination of when the recall is cut off for specific model years. I would like for NHTSA and Toyota to analyze this issue as the model year 2012 Tacoma could be at risk. I have case with Toyota Customer Resolutions that has been closed. Thanks for your attention into this matter.”

“Will not fix the frame. my husband has a 2005 and it looks new compared to my 2012. The last mechanic I used told me not to bring it back to him to much rust. Toyota said it passed their inspection. There is no way. They’ve had my truck almost a yr. I thought they was fixing it. No they just been chilling. They never called me to tell me it was they wouldn’t honor the recall. Nothing. I keep reading on here cold climate states are the only complaints. Someone is lying on here because I know at least 20 Toyota Tacoma owners from Texas who have filed incident reports.”
