Volkswagen is recalling some 13,172 model year 2012 Audi Q5 crossovers, built between June 21, 2011 and December 9, 2011. At issue is a front sunroof glass panel that may not have been manufactured to specifications, and can shatter in extremely cold temperatures.

While no accidents or injuries relating to this defect have been reported to date, falling glass could injure driver or passenger and increase the likelihood of a distraction-related crash if failure occurs as the vehicle is being driven.

Audi was able to replicate the sunroof breakage in a limited number of samples tested under laboratory conditions, at temperatures as low as -40℉ (-40℃). A decrease in reported incidents during warmer months seems to confirm that the defect is most problematic in extremely cold weather.

The recall is expected to begin on or about August 7, and Audi dealers will replace the front sunroof glass on affected Q5 models at no charge to owners. Those with questions or concerns can contact Volkswagen's customer service at (800) 822-8987, referencing safety recall number 60B2/L3.

The latest information on this recall can also be obtained from the National Highway Traffic Safety Administration’s Vehicle Safety Hotline, which can be reached at (888) 327-4236.
