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 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.

One by one, all four electronic door lock actuators that lock and unlock the vehicles doors stopped functioning. The local dealership replaced them, one at a time until all four were working again. This was covered under my extended warranty that I had purchased with the vehicle. Now, at 84,000 miles, two of the door lock actuators have failed again ! this time, the dealer told me because the extended warranty expired I was out of luck and would have to pay roughly $500 per door to have it fixed! my response was " this is a pre-existing condition, so they should be replaced by Toyota". the service rep told me that the parts were only warranteed for one year. The dealership contacted Toyota, and submitted all of the paperwork from my previous problems. Toyota responded with a "too bad, we're not going to do anything to help you". so, here I am with faulty door locks that you think are locked, but are not. Which leads to a safety and security issue for me and anyone that rides in my vehicle. After doing some research on the internet, this seems to be a common problem with these trucks. I'm wondering why there hasn't been a recall regarding this safety issue.

2007 Toyota Tacoma sua (sudden unintended acceleration) my incident started from a near standstill with my right foot firmly on the brake. As a formally trained observer and troubleshooter of aircraft electronic systems, it is my opinion that this vehicle delivered uninitiated stimulus to the electronic throttle control system. I am 100% positive about this finding as I personally experienced this failure with a clear mind and excellent vantage point. I was finally able to stop this vehicle after violent and aggressive braking was applied while contacting a cement picnic table. This finally occurred just short of a 267 foot cliff/hill pointing into a reservoir. This is my second entry into the NHTSA database concerning the unintended acceleration of a 2007 Toyota Tacoma. I have now been through the entire Toyota process and have had all recalls and investigations performed. Damage from the accident due to sua has been repaired. Toyota findings were conclusive. "could not duplicate". this means they do not have to do anything at all. I have to date engaged in extensive research of this phenomenon and I am shocked as to the findings recently announced by ray lahood and nasa that exonerates electronics as a possible issue. I have been supporting, maintaining and troubleshooting electronic problems since 1980 and consider myself a credible professional technician. This was definitely an electronic ghost in the machine.

The contact owns a 2007 Toyota Tacoma. The contact was driving 15 mph and applied the brakes when he lost control of the vehicle and crashed into a wall. The air bags did not deploy. The contact stated there was a electrical malfunction that occurred before the crash. The contact was able to drive the vehicle from the scene and took the vehicle to the dealer where the dealer performed a diagnostic test and discovered that the spiral cable assembly had malfunctioned. The dealer replaced the spiral cable assembly but the contact stated that after the repairs, the vehicle still experienced major electrical problems. The contact believed that the vehicle was unsafe to drive. The failure mileage was 67,142...updated 05/19/16

While on a camping trip my 2007 Toyota Tacoma suffered a sudden unintended acceleration event. While applying the brakes and coming to a stop the Tacoma suddenly accelerated and flew over two good size boulders a cast iron fire pit and came to a rest after hitting a solid concrete picnic table. A report was filed with coho campground hosts acting as to go on file with the Washington state forestry department. This even occurred at the wynoochee dam and reservoir located in the pacific northwest of Washington state. The truck was remanded to Toyota of olympia Washington and the insurance carrier was notified. The truck was due for the well documented Toyota floor mat, gas pedal and braking acceleration override modification. Now listen carefully here...the floor mats were heavy duty rubber non-Toyota brand mats. They were not impeding the gas pedal in any way shape or form. The truck accelerated instantly while braking and almost at a dead stop. Review of NHTSA findings on this issue are shocking. I did not hit the accelerator by mistake, there is a huge difference in the size, feel and consistency of these two incredibly different pedals. Many children and campers were present in this campground, the sheer luck that no one was killed is a matter of fate. The fact I am writing you from my living room and not a jail cell while being held for vehicular manslaughter is a miracle. This is not driver error, you have a bunch of 4 wheel time bombs out there traversing the nations highways. With over 30 years in technical electronic systems I assure you this truck accelerated from an almost dead stop while my right foot was on the gigantic break pedal, not the little tiny gas pedal. Hear me, believe me..... end of story.

2007 Tacoma truck. Upon starting truck it went into a hi-speed idle pegging the tach. Turned off ignition and restarted after about 5 seconds. Same result. Waited about 10 seconds normal operation on third start. It sounded like a jet had landed in my drive way. Called dealer. Stated that unless check engine was on there is no trouble code to be displayed. As of this date (8-30-10) I will not let my wife or anyone else drive this auto.

The speedometer will start to jump from your current rate of speed to anything below that. It started on Sunday late after noon on Sep. 15, 2008. Then the cruise control would accelerate on its own when in use. Both have continued to happen since then, accept now the truck is not getting very good gas mileage, the gauges stopped working all together, and the check engine light is now on. The truck is at the dealership as I type this being looked into. There is a serious problem from what I can see when I drive it. Something electrical for sure, and possibly elsewhere internally. I am concerned to have my family in the truck with me at times from the way the truck drives. Another concern is the warranty will be up in a few thousand miles and I am concerned that whatever the electrical problem may be, they could try to sugar coat it so it last a couple thousand miles, then they are not responsible for it. I just want it fixed and safe for my family.
