Porsche Recalls Vehicles with Defective Windshield Bonding

Atlanta, GA – Apr. 11, 2017 – Porsche Cars North America has recalled a number of sports cars with defective windshield bonding, according to documentation filed with the National Highway Transportation Safety Administration. The recall impacts various models produced in January 2017, including:

  • 911 Carrera cabriolet
  • 911 Carrera S cabriolet
  • 911 Carrera 4 and Carrera 4 cabriolet
  • 911 Carrera 4S cabriolet
  • 911 Targa S
  • 911 Targa 4S
  • 911 Turbo cabriolet
  • 718 Boxster and Boxster S

The Defect

Affected models have improperly bonded windshields that fail to comply with the Federal Motor Vehicle Safety Standard regarding windshield mounting. The adhesive used during the manufacturing loses its sticking properties, allowing for separation between the windshield and vehicle frame. Should a crash occur, the windshield may separate from the vehicle body, further endangering occupants.

Timeline of Events

Porsche engineering personnel discovered the ineffective windshield bonding during post-production repairs Jan. 24, 2017. All of the vehicles in the batch were reviewed and deemed defective. Porsche then analyzed the fabrication process and other associated vehicles to determine a root cause. On Feb. 17, 2017, quality control officials at the automaker came to the conclusion that the defectives were the result of faulty production methods out of step with established company standards. Due to this deviation, the windshield adhesive was improperly mixed, rendering it ineffective. Porsche also found that the defect only affected convertibles, as these models exhibit unique windshield stress ratios.

The Porsche product safety committee reviewed the information and chose to launch a voluntary recall.

The Solution

Porsche has directed dealers to replace the windshields in affected vehicles, free of charge. Because the models are still under warranty, the automaker does not intend to issue reimbursements, according to NHTSA documents. The timetable for dealer and owner notification has not yet been established.
