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.

Failure Date: 02/17/2015

Driving my Toyota Tacoma, I was approaching a steep decline. I tapped on the brakes and continued driving at approximately 27 mph when I down shifted to accommodate for the snowy road. As I was down shifting the truck lost control and slid sideways causing the front passenger side to hit a snow bank. Once the truck struck the snow bank it flopped over on its driver side. The side air bags on both sides came out but did not inflate. The driver side bags were torn. I found evidence of this with shredded pieces of the air bag found in the vehicle. Additionally the driver side front air bags never deployed.

Failure Date: 12/21/2014

While driving the vehicle loses pedal response due to the throttle control motor shutting down and the check engine light coming on. The engine either shuts down completely or the becomes very jerky and cannot sustain an idle. Incidents began to occur around 95,000 miles odo but stopped for several years after a mechanic worked on the vehicle and said the throttle position sensor was out of alignment. More recently the truck has again been experiencing the same problem as before: loss of pedal response, and in addition it now shuts the engine down and the gauges shoot up to the top of the charts and tick unresponsively until the key is removed from the ignition. This has occurred multiple times now in traffic and along the roadway where the truck becomes unresponsive and is difficult to drive safely off of the roadway.

I was driving at a normal speed on the highway. The gas pedal became unresponsive. I had to push the pedal all the way to the floor in order to get up to speed. The check engine light came on and the transmission had trouble switching between gears. This problem occured intermittently and continues to happen. The code that has come up is to replace the throttle body, which I have two separate times, but again the new replacement part is quoted at $1000.

Failure Date: 08/01/2014

Front running lights melted the plastic causing charring and a fire. Pictures were sent to Toyota national headquarters safety personnel under file # 1408062678, incident 14809-000124. Toyota acknowledges there is an issue with 2005-2011 Tacoma¿s and stated this condition was covered under a "warranty enhancement program" and the deal would correct the problem. I contacted the local dealer and was told my VIN number does not qualify. I inquired profusely as to the process used to determine the VIN number range, how this problem is being fixed and was told these are not publicly released documents. I was not offered a method to fix this condition to prevent it from happening again -- "we apologize but are not in a position to avail a point of contact in Toyota safety management to discuss your case. As we have provided our position on these matters, we do not have further information to offer in this regard. " robert browning Toyota customer experience. I have searched the NHTSA data base and see others are having the same problems under NHTSA 10523691, 10510776, 10457435, 10448124, 10427052, 10405463. I ask that Toyota be responsible to vehicle owners and be required to re-examine their VIN range on this particular problem. The front turn signals are charred and melted so badly they are extremely hard to see and will lead to future accidents. The plastic also heats up enough to cause melting and fire potential in these vehicles.

The day time running lights that also doubles as turn signals are burning a hole through the plastic lens inside the headlights and cracking the lens as well. These are a known issue with Toyota and they put out a t-sb-0129-11 on September 7th, 2011 and called it an "appearance concern". It is also a fire hazard as I don't believe the lenses should be melting.

While driving down the highway, I moved into the left lane to pass another car. When I stepped on the accelerator the nose pitched forward and the engine felt like it was not getting any gas. I was able to press the accelerator nearly all the way to the floor to continue getting power to the engine, but the first 2/3 of the pedal stroke were completely unresponsive. A check engine light came on and it was diagnosed as a throttle body issue. After doing some research, this seems to be a well documented issue on a number of Tacoma forums. The cost to replace will be $1400 dollars new or $400 dollars used. I am skeptical to purchase a refurbished part due to the known issue with it. This has happened a total of 6 times in 3. 5 years of owning the vehicle and seems to occur in colder weather. Typically after pulling over and shutting the car off for 30 seconds, the issue is gone. It will undoubtedly happen again, but you never know when.

Failure Date: 11/11/2013

On a recent inspection of the lights on my vehicle I noticed that the daylight running lights (drl) were melting both left and right headlight assemblies. The light bulb retainer is discolored indicating signs of a high heat. My Toyota dealership confirmed there is a problem with the drl's, however they were only replacing the headlight assembly if the vehicle is under warranty. I then contacted Toyota customer service and asked if there was a fix for the headlights, they confirmed that there is no fix and they will not replace the headlight assembly. The problem is a potential fire hazard. An internet search provided numerous accounts and pictures of this chronic problem. I would like Toyota to correct the hazard and repair the damage to my vehicle. Again the biggest issue here is that if Toyota replaces the headlight assembly it will be with the same components that cause the problem.

The air bag sensor came on in my '09 Toyota Tacoma. The vehicle was brought to a mechanic and a diagnostic test was run. The diagnosis was a faulty air bag spiral cable. This identical issue forced a recall of 481,000 Tacomas, including '09 vehicles. However, I was told that my truck did not fall within the VIN # database that is covered by the recall. This is resulting in an out of pocket repair costing $500. I find it hardly coincidental the exact same design flaw that affected nearly 500,000 vehicles just popped up in my vehicle. Without spending the $500, my barely 4 year old truck will not pass inspection in the state of MA. I bought a Tacoma based on it's reputation for reliability. Currently I am breaking the bank just to make it legal to drive on the road.

My vehicle daytime running lights (drl), are burning through the lenses. The lens in front of the bulb is discolored and seems to be melting and cracking due to overheating. The plastic is dark and looks burned. Because of the defect there is concern for driver safety as there seems to be an obvious fire hazard that has not been addressed by Toyota. This problem exists in both of my front headlights.

Both left and right dtrl lenses are melted from heat from the bulb, I am worried about an electrical short, or fire. Dealer says it is cosmetic and does not want to replace headlight assemblies since vehicle is out of warranty. I believe this is a safety issue that Toyota motor company should address with urgency.

Daytime running lights generated enough heat to melt the interior colored lens on both headlight assemblies, I noticed discoloration and cracks in the colored lens within 1st 12 months. More recently the colored lens began to melt and run, looks as if they were exposed directly to flames. There is also noticeable heat damage to the clear exterior lens cover near the area of the drl. Toyota issued a service bulletin but did not notify owners of the potential fire hazard this may cause. Heat damage has clearly become more severe over time.
