Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

The vehicle was taken to an independent mechanic who diagnosed that the failure was due to excessive electrical power traveling to the headlight assembly and the light assembly needed to be replaced.

Both driver and passenger headlights are melted, burned and grey in front of the daytime running light bulbs. Google search indicates that it is a fairly common issue. Called Toyota and was told that there was nothing they would do to correct the issue.

Highlander Hybrid

  • 75,000 miles
The headlamp covers on my 2006 Toyota highland hybrid show significant melting exactly where the day lights shine through the plastic. This is definitely a defect in the materials, as the lights cannot be turned off by the driver. The vehicle has just 75000 miles, & the lens covers & bulbs are the original equipment. The dealer refused to correct this without approval from Toyota. Toyota refuses to acknowledge that this is a defect and will not replace the lamps and/or the lens covers. I believe this is a safety hazard, as others have reported fires started by the overheated lenscovers. Another hazard is that as the lenses further deteriorate, they will allow water and moisture to seep in, increasing the risk of an electrical short. Although the warranty has expired, I feel that Toyota should be admitting that this is a safety issue and a mfg defect, and replace the light units. Instead, Toyota representatives have repeatedly stated that they haven't heard of this problem before, and will not take any corrective action.

The headlight bulb on 2006 Toyota Highlander hybrid is so hot that it has discolored and slightly melted the lens cover. This plastic gets so hot that to be a safety hazard that could cause burns to individuals that might come in contact with the lens and/or the spuer heated lens plastic could become a fire hazard.

Lens is melting in front of day time running lite bulbs on both left & right sides of my 2006 Toyota Highlander hybrid.concerned this could cause fire as this is also the high beam lite. If left on accidently these could become very hot as the halogen bulbs will actually melt glass.

Highlander Hybrid

  • 83,000 miles
Plastic headlight lenses are melting directly over the daytime running light (drl) halogen bulbs on both sides. The lights are the same as the 'brights' but should be at 50% power when used as drl's. dealer informs me that they have never had this complaint and cannot find any other instances on-line or in their database, but there are several that I found within a few minutes of searching. At this point, it is only covered under the 36,000 mile warranty, but as this is a significant defect in either the plastic lens covering or in the bulb itself (running too hot) or in the drl relay that should be at 1/2 power, I would like to submit this for your consideration
