Typical electrical symptoms owners report

  • Rear taillight housings fog up, crack, or fill with water, sometimes worsening over time and raising concern about brake light visibility to other drivers.
  • Rain-sensing wipers activate on their own in clear, sunny weather, and the cruise control display flickers between screens while driving.
  • Interior electronics behave erratically, including dashboard warnings appearing when not applicable, navigation showing incorrect directions, and interior lights turning on and off.
  • Backup parking sensors and park assist intermittently shut off without warning, sometimes going undetected while backing up.
  • Headlights fail to properly illuminate the road on dark or hilly roads, described as having a dark upper half that limits visibility going uphill and downhill.
  • The power liftgate has closed without a safety stop or reversal, in one case striking a person standing nearby.

    Electrical system:wiring

    Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2016 Highlander vehicles manufactured May 26, 2016, to September 16, 2016. The brake fluid level sensor may not be connected to the wire harness, preventing the sensor from detecting the brake fluid level. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 135, "Light Vehicle Brake Systems."

    Risk: If the brake fluid level is low and is not detected, the braking performance may be decreased, increasing the risk of a crash.

    Remedy: Toyota will notify owners, and dealers will inspect and, as necessary, connect the wire harness to the sensor, free of charge. The recall began November 14, 2016. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this G03.
