Hazardous safety issue. Possible manufacturer defect to electrical system on 2001-2007 Toyota Highlanders. While driving at high or low rate of speed, there has been many close calls of being hit from behind due to the manufacturer defect to their electrical components or wiring in specific to rear braking lights. When depressing the brake pedal the rear passenger brake lights do not come on. Light bulbs changed, fuse was checked and connectors checked. There has been multiple identical related issues reported by consumers on many blogs and forums online. Only remedy mentioned was to have the Toyota dealer to replace the electrical braking component or circuitry. This should be a recall for the Toyota Highlander 2001-2007 on the critical braking systems on these vehicles. Why do consumers have to pay upwards of $400 to replace what appears to be a manufacturer issue. This is a accident made to happen. Also due to their poor design, the vehicle can't pass the state's vehicle safety inspection.
