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.

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.

Failure Date: 07/26/2013

Upon purchase of a 1998 Toyota Tacoma from lithia Toyota of missoula, montana I was presented with an odometer disclosure statement stating the vehicle had 168,143 miles. While test driving the vehicle earlier on paved highway I noticed the odometer read 168,000 and something miles, so signed the disclosure statement in good faith of the dealer. I also had requested a vehicle history report. After the test drive, the salesman handed me an autocheck vehicle history report. He did not explain details of the report to me, although it seemed fairly straightforward. Heading the odometercheck section, in bold letters it stated "your vehicle checks out!" it continued by stating "autocheck examined the reported odometer readings reported to autocheck for this 1998 Toyota Tacoma sr5(VIN#) and no indication of an odometer rollback or tampering was found. " because I had been warned about used vehicles and accidents I focused on the accidentcheck and title and problemcheck in the report. It wasn't until the odometer went out driving on gravel a week later that I realized the odometer was flawed. And it doesn't record the mileage when it is out. On closer inspection of the vehicle history report, there are six reports underneath the odometercheck section. The suspect mileage is between the 2nd and 3rd mileage reports. The 2nd mileage reports 15,000 miles 10/09/98 with a notation stating: "not included in rollback calculation. " the 3rd mileage reports 10,038 12/10/1998. That is a difference of -4,962 miles lost on the odometer. I phoned, then brought the Tacoma back to lithia 8/6/13. The man in the service department said they found no problem and recommended replacing the circuit board at my expense. There was nothing they could do, he repeated. I wrote a letter to Toyota corp. 8/9/13 and received a response by phone 8/20/13. The analyst stood by lithia's decision 8/23/13.

The plastic housing/plastic lens covering the amber daytime running lights and the clear fog lights are burned, melted, cracked and broken. This is not due to any front end collision but due to the extreme heat generated by the original factory-installed light bulbs. The lights are generating so much heat that they are melting, burning and cracking the plastic housing which then breaks under driving stress. Compounding the problem is that there is no way to turn off the daytime running lights when the vehicle is in operation. Either the daytime running lights must be on or the headlights must be on. Therefore, the lights continue to burn the plastic housing. Toyota will not competely cover the cost to repair and replace these defective light systems stating that the vehicle is out of the 3 year warranty. Although the vehicle is one year out of the 3 years manufacturer's warranty this problem did not occur overnight but is the result of 4 years of use. The lens have been progressively getting worse over time. Because the lens are burned, we are concerned that a fire could occur.

I'm filing the compliant to acknowledge the fact that these older fly by wire throttle bodies have a faulty tps that is only replaceable as a whole new throttle body. The cost on them is between 700 to 1000 dollars. My Tacoma do have a faulty tps on it. I'm waiting to save up enough money to replace the throttle body however, there have been numerous times that upon pulling out into traffic it has acted up. When this happens you get a very bad hesitation or lack of acceleration to the point of endangering myself and other drivers. The hesitation has lasted as long as 3 to 5 seconds before the throttle will finally respond. The condition will only happen during hot summer months. Thank you for your time and would like the see this looked into and or resolved. I will be able to replace the throttle body because I work at a dealership and get the parts at cost. However some people may not be able to save up the cost for the new part. Thanks again sincerely!!.

Inside the front left and right headlight assembly is a combination turn signal indicator/ emergency flash indicator/daytime running light. The lense for this combination indicator inside the headlight assembly has melted and affected the integrity of the component. I contacted my local dealership twice and Toyota customer satisfaction by telephone. But they did not offer any additional information for correcting the problem, except for total replacement of the complete assembly at my expense. By the regulations of the federal government with the dot Toyota should comply with part 564 of the safety regulation requirements, and by this should notify owners of the optional replacement parts as a service bullitin with a mailed notification letter. Because of this oversight Toyota has chosen to adapt a stratagy to use an exception to their warranty contract by limiting their responsibility in effect of component exclusions I. E. Light bulbs because of Toyota's inabillity to recognise and address this issue with a notification. Many of the dealers and owners who could have corrected the improper matching of the assemblies, before damage to the integrity of the signal indicators required safe operation was lost and Toyota gained considerable financial advantage at the expense of safety.

Daytime running light bulbs on both headlight assemblies have burned straight through the orange plastic covers, causing them both to bubble, and crack in half. This is now causing the entire headlight assembly to fog over! bought truck brand new from dealer so these are the original, factory equipped headlamp assemblies. They have never been changed.

I have a 09 Tacoma and the drl's have actually burned, melted and popped the lens in front of them. Also, the bulbs themselves, upon examination, have burned the socket in which they are held. You can see black around the base of them. Took it to Toyota at 59k miles and I have the platinum 7year/100000mi warranty and was told it would cost me 1100 for parts alone to fix, offered no help and lied to me and said they have had no other incidents of this nature and its a rare problem never before seen. I have removed my drl bulbs out of concern of a fire starting and then I probably get stuck with that bill of a burnt front end. I should not have to pay because Toyota put in a bulb that's too hot or because Toyota decided to make a cheap plastic cover for the bulbs. I had zero influence on this failure. There are countless posts on all kinds of websites concerning this problem. I can track down over 1000 in less than 30 min. Please help. When I call Toyota I just get bullied around and talked to like I'm dumb or don't know what I'm talking about.

The drl (daylight running lights) bulbs were designed to close to the lens cover and the bulb is to hot. It burnt / melted the lens on both the right and left headlights. It leaves a dark spot ( approx 2. 5 inches in diameter) . It happened when the outside temp was hot (greater than 105 deg f) and the running lights were on (they come on automatically when truck is started). I have looked on line (google search) and a lot of people are experiencing there headlights having a melted / burnt spot on both the right and left sides. The local dealer says there is no fix or recall currently. I have read that some people were getting this problem fixed if the mileage or time was within the warranty. Mine occurred after. I believe this could be a fire concern and the burnt spot is semi blocking the performance of the drl. The drl is so people can see you coming. There needs to be a recall!.

My trucks headlight unit has daytime running lights "amber turn signal lighting" and its continued to cause melting around the housing. This has been going on for a year now and the dealership has been informed on more than one occasion and they refuse replacement because its not a declared recall from Toyota. The light issue continues to get worse and is almost completely melted around the turn area.
