One problem related to rear window defogger has been reported for the 2006 Toyota Camry. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Toyota Camry based on all problems reported for the 2006 Camry.
The defogger wires in the rear window reflect headlights and glare from behind the vehicle. It creates a prism effect, with 10-12 lines showing both above and below each and every headlight or bright light source behind the vehicle. The image you see in your rear-view mirror is false, misleading and distracting. Changing tint and/or mirror does not affect the problem. The rear windows need to be replaced with a different design that includes defogger wires that have a non-reflective surface.
