2011- check engine light was illuminated. Toyota dealership attempted repairs 11 times but could not find a cause. They replaced 7 different sensors, replaced gas cap, charcoal filter. . Still could not get light to go off. Refused to continue servicing same issue with no fault. Since 2011, I have had to run diagnostics on a regular basis to ensure there are no other mechanical issues. 2022- gas tank fell off of truck while driving. The straps snapped off due to rust and tank fell to the ground. This issue could have caused great bodily injury or death. 2023-lost brakes while driving. Total brake failure. Local mechanic stated it was a proportioning valve failure. The housing for it was rusted through and cannot be removed safely. After multiple days of research, a replacement could not be located. Even contacting Toyota, part is unavailable so vehicle cannot be fixed. Total brake failure could have led to great bodily injury or death. Ongoing-- vehicle frame is extremely rusted. Bumper has fallen off, spare tire fell off, brush guard rusted and fell off. The frame under cab near bed of truck is rusted through. Gas tank straps rusted through and tank fell off. You can literally push fingers/hand through the flaking metal. All previous recalls were completed including undercoating but the rust has gotten so bad the vehicle is not safe to drive.
2004 Tacoma frame so rotted that upon hitting a large hole would finish off the rusted frame. This type of rust and erosion is not from normal wear. . This is due to the manufacturing of the vehicle and they will not replace. They say they are aware of it. . But time lapsed to get it fixed?? so what now I am out $15k on a 16 year old truck. Since when did recalls have an experation date??.
On several occassions my truck has completely lost power. A few times it happened while pulling into traffic resulting in me almost being hung out in a busy intersection. When I push the gas pedal, it starts to move forward, then suddenly loses power. I beleive the problem is somewhere in the throttle body. I also get some hesitation when lightly hitting the accelator at highway speeds.
