“I traded my 2012 Toyota Tundra for $17,000.00. Blue book 'trade-in' value was approximately $20,000.00 - $21,000.00 at the time. My truck had low mileage and was in excellent condition, except for the undercarriage rust. I lost $3,000.00 - $4,000.00 in the trade-in.”

“Secondary air injection pump and secondary air injection switching value causing check engine and trac control lights to come on. I was told by the dealer that the same piece and design was recalled on the 2011 but not the 2012 Tundra. It comes on and off but when it is on it feels like that there is a limp mode making it difficult to get up to speed on the highway. The steering feels different which I think is the traction control.”

“I had a sudden jump in my rpms and accelerator malfunction I had to carefully guide the truck to the side of the road. After it died I could not start it. The engine light flashing, the 4lo flashing and traction's all flashing. I still had electrical but no power. I was being followed by another vehicle who almost hit me and my daughter. These trucks are supposed to be know for their life span and safety. This is not what I call safe by any means.”

“A light came on and it started losing power. Took it to the shop and was told it was bad gas. I put the cleaner in it and it didn't fix it. I had some buddies tell me to unplug my battery because it sounded like a safety feature. So I did. The light went off and the truck acted right for a few miles then started doing the same thing. Vehicle was in motion on the highway. My buddies referred to it as a limp mode or something like that. I was afraid to have it worked on because I was told if there was a recall the manufacturer wouldn't be liable.”

“Please refer to TSB 0160-11. Toyota recognized that inferior quality parts were used as part of their emissions system and wrote this TSB as a remedy. The problem I have is that they continued to use the faulty parts beyond the 2011 model year cut-off in this TSB. My truck is throwing the same engine and emissions codes associated with this TSB. It also forces the engine into a low power mode greatly reducing the ability to accelerate. Lastly, it turns off traction control which affects the stability of the truck. …”
