I just heard from my local dealer that I've been trying to work with concerning the melting lenses in my '09 Tacoma TRD. I tried to get Toyota to replace the lamp assembly and they would only cover half ($500) towards the replacement and subsequent re-aiming of the head lights.
I then printed out the instructions (found elsewhere on this Forum) to install the relay and jumper wires to turn the DTRL function off, leaving the turn signal function alone. According to the dealer, Toyota will not sign off on, nor allow their dealers to make this modification.
I've asked that I be provided copies of all the paperwork related to this issue concerning my truck so that I may contact Toyota corporate. I'll be expressing my extreme displeasure with their handling of this issue especially since it is a known issue with this lamp assembly. This is my first Toyota vehicle and we are currently looking for a new vehicle for my wife. But, if Toyota does not make this issue right, not only will I not buy a new Toyota, I will not recommend nor will I ever purchase another Toyota vehicle. In fact, I will advise anyone coming to me for advise to not consider a Toyota due to their lack of customer service and failure to correct a know fault in a critical and necessary safety component of the vehicle.
I would also strongly suggest that every member on this Forum having any issue (melting, bubbling, cracking etc.) with the DTRL's write Toyota Corporate expressing their deep disappointment with the quality of Toyota products and the Corporations lack of concern for the customers safety buying the product. With all the negative that Toyota has received during the past few years over safety related issues, you would think that Toyota would be falling all over themselves to correct a known safety issue in a required system, instead of tap dancing around like they are doing.
