| Problem Category | Number of Problems |

| Tail Light problems |
The low beam headlights are melting the plastic cover on the headlight assemblies. Both sides are melting from the heat of the low beam light bulbs. It was first noticed at 37,000 miles, at 3 years old. Factory installed parts, no modifications have been done to the vehicle. The low beam lights are only operating at night, about 25% of the driving time on the vehicle, so the melting occurred within approximately 10,000 miles of driving time. The vehicle was out of warranty when it was reported to Toyota, but this melting has been occurring since day one. This defect will affect the safety of nighttime driving in the vehicle. Worked for months with dealership, unsatisfactory resolution.
Rear lights located both on the tailgate and body of the vehicle. The lights covers failed to remain adhered to the lights themselves and fell off and are partially adhered as a result of what appears to be a failure of the adhesion material . Two light covers may have been lost while driving. Unknown if their loss resulted in damage(s) to others. Without the outer cover results in the exposure of the lights to weather and potential failure. Review with Toyota of orange service manager confirm the failure of adhesive/ manufacturing process of the lights.
