The National Highway Traffic Safety Administration has closed an investigation into 24,000 Porsche 911 vehicles, saying there is no need for a recall.
After receiving 10 complaints alleging a sudden loss of coolant, NHTSA began investigating model year 2000 to 2011 Porsche 911 vehicles, and has since looked into 63 complaint filings and 336 warranty claims for the problem.
Pipe ends that were joined with epoxy to cooling system components were called into question, and Porsche told NHTSA that it already knew of an issue with a supplier’s application of the adhesive. This resulted in elevated failure rates in about 6,800 early production vehicles built for the 2007-2008 model year.
Besides this small amount of cars skewing the overall number of issues, most of the issues did not result in the fittings completely disconnecting, and many customers detected the problem while the car was in park. Also, NHTSA says no accidents or injuries have been reported as a result of the issue.
“A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted,” says NHTSA. “The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances.”
