— Porsche won't be asked to recall thousands of cars after the National Highway Traffic Safety Administration (NHTSA) closed its investigation into antifreeze leaks in the 2001-2007 Porsche 911.

In April, 2013, NHTSA opened the investigation after receiving reports of sudden antifreeze loss allegedly caused by a separation of pipe ends in the cooling system.

Porsche submitted reports suggesting a problem with the adhesive used to attach coolant pipes in about 6,800 model year 2007-2008 Porsche 911 cars. The problem was fixed by the supplier and according to NHTSA, the initial problem wasn't as bad as first thought.

Most of the complaints didn't appear to involve a complete separation of the fittings and didn't occur while driving. Further, no injuries or crashes were caused by the leaks.

Based on these findings the investigation is closed. NHTSA will take further actions if additional information of a defect comes to light.
