2005 Toyota Tacoma Owner Comments

The catalytic converter shield on my 2005 Tacoma fell off while driving and almost caused an accident. After picking up the large metal parts and inspecting under the vehicle, I noticed that near to where the catalytic converter sits, that there was extensive corrosion on the truck's frame and even a large hole. I am extremely worried about the safety of the vehicle and am afraid that the frame may crumple while driving causing an accident or death. Toyota is aware of the issue. I contacted the corporate offices, but was told that Toyota is only replacing the frame on vehicles registered in what they have designated as a "snow state". I purchased my Toyota at a dealership in Illinois (a "snow state") and have done a lot of traveling within the "snow states", yet because I live 25 miles away on the Missouri side, Toyota is refusing to cover the repair. The woman from Toyota corporate did not seem to care when I told her that I was worried about the safety of the vehicle and that it could result in an accident or death. I offered to email the photos of the frame corrosion, but was rejected. Toyota needs to cover this repair on all vehicles with frame corrosion regardless of the state they live in.

On May 27, 2013 my wife [xxx] and I were towing my bass boat and I blew out the rear passenger tire and was able to safely get it off of the road to change the tire. In the process of changing the tire in my truck, the frame bent under the pressure of the jack and the truck, came off of the jack, luckily I had the tire partially on that the lug bolts caught the truck. This rusting and unsafe frame issue dates back to 1/16/13 at approximately 7:30 am I was contacted by the Toyota dealership that during a repair to my catalytic converter they noticed that I had a hole in my frame and that it would not pass inspection. I feel terrible now, but I all but called the girl service manager a liar and asked that she take me a photo of the hole and send it to me at work. I want my Tacoma fixed, the frame replaced as I feel it is unsafe and after having experienced the truck falling off of the jack after the frame bent while simply jacking it up, I can't imagine that I am the only one out there with this issue. In my research I am finding volumes of complaints to Toyota in kind regarding frame rot and rust. I have also noticed some instability when driving, it seems to have a constant shake in the steering. I have placed numerous calls to Toyota's customer service explaining in detail my safety concern and the answer I am constantly being given is that my vehicle is not currently part of the recall program. Any way you slice it, I feel this is terrible on Toyota's behalf to subject loyal customers to such potential and eminent safety hazards as a week and inferior frame! god help us if we are ever involved in an auto accident... how well will these frames hold up or will we be crushed like a soda can" so much for Toyota's safety rating at that point right" please help me...please help me. Sincerely a concerned Toyota owner, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Frame at passenger side motor mount is cracked and failed. Because it's very unusual for a truck frame to crack, notified Toyota (hilo, Hawaii) of the problem and asked if there is a recall to address it. Toyota said it's normal wear and tear and there is no recall.

To who it may concern: Would you be able to research and cover a 2005 Toyota Tacoma problem plaguing Toyota customer. The issues is a problem with the design of the frame. The frames are failing at the engine motor mount(very very dangerous) and causing the cars to be almost be in-repairable(Toyota advise me it would be 10,000 fix). Toyota is offering no assistance and there are tons of customer feedback online to show there is a problem with their frames. For my truck I heard a noise coming from the engine on 12/24/2012 and took into a dealer on 12/26/2012. They said it was the fan hitting the fan shroad they said they fixed it. I started hearing the noise again and had to take it in on 1/5/2013...they first said it was my motor mounts and would need to order the part..when they were going to install the part they notice a crack in the frame where it connects to the motor mount. They said there was no other signs if damage any where and did not know how that happened...meaning the frame failed from the torque of the engine.. they advise I would need to get new frame ($10,000)...I called Toyota and advise they would not assist.

Truck began making loud noises in engine compartment. Truck was diagnosed as having bad motor mounts. At time of repair, motor mount assemblies were noted by mechanic to have broken off the frame due to bad/weakened welds. Motor is rubbing on fan/radiator shroud. Owner has done independent research, including complaints filed on this site, and has noted that this has been an on-going issue with 2005 Tacoma.

I own a 2005 Toyota Tacoma. On several occasions the vehicle has shut down when I attempt to proceed from a stop. This occurs while I am in traffic. The vehicle may or may not start for some time after that. If it does start, it will idle ok but when I step on the gas pedal it shuts down. After continually starting for a few times it may run ok for a while. I had it serviced at a dealer the first time and they ended up replacing the computer system. It worked fine for about 3-4 months but then began doing it again. I took the vehicle in for service at the dealer again and they find nothing wrong. It has happened to me about 6 or 7 times now.

The contact owns a 2005 Toyota Tacoma. While driving between 35-40 mph, the contact heard a loud knocking and grinding noise outside of the vehicle. In addition, the check engine and ABS warning indicators were illuminated on the instrument panel. Suddenly, the vehicle stalled and the warning indicators remained lit until the engine was turned off. Roadside assistance was called to the scene and the vehicle was towed to an authorized dealer for diagnostic testing. The technician stated that the rear pinion and gear failed. The vehicle was repaired, but was taken to an authorized dealer on two separate occasions for identical failures. The vehicle was repaired twice under warranty. The failure mileage was 25,000 and current mileage was 82,000.

I was traveling on the freeway and was changing gears when the accelerator pedal suddenly dropped to the floor and the engine suddenly raced up to redline. I had the clutch in at the time. I checked to make sure my mat was not interfering with the pedal. This is the second time this has happened with this truck. I pumped the pedal several times but the engine continued to race. I switched to third gear and let out the clutch. This brought the RPM's down but caused the vehicle to begin rapid acceleration. I pushed in the clutch and the engine went back to racing at redline. After pumping the pedal for several more seconds the engine went back to normal idle. I put it back in gear and continued with my trip. I worry about how a less experienced driver might handle a problem like this. I am also concerned about what this behavior might do to engine life if it keeps repeating.
