Failure Date: 07/10/2017

Driving at high way speed; the abs light, parking brake light, traction light, lost power to windows, a/c, radio, power steering, engine was running rough, then the check engine light came on. Could be a safety issue of control of vehicle for drivers not paying attention. Toyota dealer said the root cause was a bad cell in battery that caused the ign#2 fuse to be blown. These batteries have known issues to be bad from the factory. Reported earlier about 30000 miles the factory battery would not start vehicle and dealer said they replaced because of a bad cell. I own a 2008 Toyota Tacoma also , same model and make as being reported and that battery has been replaced 2 times for same reason.

The contact owned a 2008 Toyota Tacoma. While driving 70 mph, the contact looked in the rearview mirror and noticed flames between the vehicle cab and bed.

The hvac fan electrical connection burned and melted. I could smell burning inside my truck. My mechanic found the hvac blower fan connection had been so hot it burned and melted along with the resistor. Some of the wires were black and brown. I was worried the truck was going to catch on fire! this happened while I was driving. After looking online I found I am not the only person who has had this happen! Toyota denied the problem.

Secondary air injection valve stuck open causing limp mode. Happened near very dangerous intersection and lost all power in truck. As others have stated, truck only has 50k miles and required a $500+ repair (part only) for a component of the emission system which is only used on startup and includes a warranty of only 2 years.

Failure Date: 06/02/2016

My truck was recently damaged from rodents,they built a nest by engine and chewed wires. After further research I found that auto manufacturers in order to go green are using soy based products on wires instead of petroleum. They are using sugar in there plastics. Rice husks in there interiors. All this stuff attracts rodents. This is unacceptable! my dealership said they are seeing at least 2 rodent damaged vehicles a week. My truck is driven daily and sits no longer than 8 hours. The total damage on a brand new truck with extended warranty was 2700 out of pocket, this damage was no covered by warranty.

The secondary air injection systems seems to fail quite frequently on these 2012 Tacomas with little to no help from Toyota to take care of this issue as a recall. These are known to fail right after your out of warranty and to charge it's loyal customers over $1000 for a part that should not fail or a part that should be covered is absurd. I have been a loyal Toyota customer my whole life but the issues of the Tacoma are making me rethink my decisions as an automotive consumer.

After driving on the highway for a few minutes at ~70 mph, the abs light run red on. When the light turned on the computer thought the car was in a bad situation and locked the brake pedal. This caused the brakes to not function and made the car almost impossible to stop. Whenever the car was able to be slowed down to about 19 mph, the light would turn off and the brakes would start to function normally. This happened once a week for 3 weeks in 2015 and again in February of 2016. It happened again in April 2016. This problem did not happen at low speed and it would not happen twice in the same day, even during the same conditions. I went to wolfchase Toyota to fix the problem. They decided not to do anything about it. I went to principal Toyota and they said they had never seen the problem before. They said that they could reset the computer or put in a new one ($3000). They reset it and for the past few months it has worked.

The contact owns a 2016 Toyota Tacoma. While driving at various speeds, the estimated mpg displayed on the message board was inaccurate. The vehicle was taken to a dealer who was unable to diagnose or repair the vehicle; however, the computer was reset. The technician also stated that the estimated mpg of fuel consumption was not calculated when the vehicle was idling. The failure persisted and the manufacturer was notified. The failure mileage was 1,000.

After 10,000 miles the airbag light came on. Then the next day the check engine light came on as well as the traction control. Called the dealership and they looked at it saying I just need new sensors. Drove it a couple more days and noticed the cruise control was non existent. I drive a lot for work and use it a ton and all of a sudden it wouldn't even bring the light on or work at all. The next day started driving and the real issues started. Turned truck on; same problems I have been having; then the truck would not shift. Kept going and going till I was getting to 5000rpm and it shifted with a tremendous amount of force. Once it shifted the whole truck did a huge jerk then went a little more an did a double shift totally bypassing the 3rd gear. I turned it off and started it again. Kept having the same problem all day. I called the dealership and they said get it to them when I could and they would take a look. Almost caused several accidents trying to get the brand new $35,000 truck that didn't work to the dealership almost running into the people in front of me who cut me off because I can't go over 40mph on the freeway and I have no control of the violent shifting moving the whole truck. Needless to say the dealership tried to blame me for all of these problems that I could not have possibly cause if I tried and that my brand new truck with 10,000miles on it was fine just needed a couple sensors. Obviously this is not working and I think sensors are the least of the worries.

The vehicle's entire electrical wire harness had to be replaced. Diagnostic code pointed to a corrosion problem with the harness hook-up point with the automatic transmission. Toyota put out a mechanic's bulletin for it's mechanics when this code came up to replace the entire electrical wire harness probable cause corrosion. The problem showed up after starting the truck, driver pushed the brake, to move transmission from park to reverse. The right turn signal indicator light lit up while brake was depressed. Check engine light came on. Right signal came on every time the brake was applied, all the way to the dealership service department.

Blind spot monitor (bsm) - from the first day I drove the truck off the lot, the bsm error message came on. This has been an ongoing issue and the error light comes on at least 3-4 times per week while driving. During my first service, the service technician said that they needed to replace a bad sensor. Its been almost 4 months and I still have not received a call back by the dealer's service department to bring my truck in for the sensor replacement.

Failure Date: 10/05/2015

2004 Toyota Tacoma v6 3. 4l 5vz-fe with automatic transmission. Toyota originally equipped this vehicle with a throttle by wire system. The vehicle unexpectedly does not respond to accelerator pedal position. Toyota on board diagnostic system does not detect fault thus does not log any error codes or illuminate check engine light. Occurrence rate and duration of events is intermittent and inconsistent. Velocity of the vehicle rapidly decreases unexpectedly and momentarily as if foot was temporarily removed from the accelerator pedal. Vehicle also unexpectedly and momentarily does not respond when accelerator pedal is depressed to begin moving or suddenly decreases speed when accelerating. This is a potential hazard in situations such as cruising in traffic, clearing an intersection, crossing railroad tracks, etc. . . Occurrence rate and duration of problem seems to be worsening over time or with increased ambient temperatures.

The vehicle was in motion at highway speeds when the truck instantly began decelerating even though I had the accelerator depressed. This problem resolved after turning the truck off and then on again. The problem recurred several times while stopped and while driving over the course of the next month. I was nearly rear ended as a result of this failure. Upon reading, and inspection by a mechanic I was notified that the throttle sensor had failed, and the entire throttle body needed to be replaced as a result. Upon researching this I did discover that this is the case the '03-'04 Tacoma (I have an 04), for which a throttle position sensor is not available, at least in the u. S. This is a very dangerous issue that several people have complained about with '03-'04 Tacoma trucks. Replacing the entire throttle assembly is an obnoxious and expensive consequence for a faulty electronic part that puts vehicle owners' lives at risk. This should have been addressed by the manufacturer!.
