What owners report

  • Engine stalls or loses power suddenly while driving at highway speeds, sometimes requiring towing.
  • Vehicles burn through oil quickly between changes, with the oil pressure light cycling on and off despite dealer repairs.
  • Backup cameras stop working when the transmission is shifted into reverse, sometimes disabling entirely while driving.
  • Steering column makes a clicking or grinding noise before the airbag warning light comes on, tied to a failing clock spring module.
  • Push-start vehicles fail to start even with a fresh key-fob battery, triggering a transmission control module communication error.
  • Tires show low pressure warnings and humming noises from the rear, with caster alignment testing failing shortly after purchase.

    Exterior lighting:turn signal

    Volkswagen Group of America, Inc. (Audi) is recalling certain 2016-2018 Audi Q3 vehicles equipped with LED headlights. An inoperable front turn signal may not illuminate an indicator, failing to alert the driver to the issue. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

    Risk: Without an indicator informing the driver of an inoperable turn signal, the driver may turn or change lanes without a signal, increasing the risk of crash.

    Remedy: Audi will notify owners, and dealers will update the body control module (BCM), free of charge. The recall began June 21, 2019. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 97DK.
