WASHINGTON — The National Highway Traffic Safety Administration has closed an investigation into an estimated 24,635 2001-'11 Porsche 911 cars after consumer complaints of rapid coolant loss.
The cars will not be recalled.
The cars are equipped with Turbo, GT2 and GT3 engines.
The cars were under investigation for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the problem description posted by NHTSA on its Web site.
Federal safety regulators looked at 63 consumer complaints and 336 warranty claims related to the problem. NHTSA had been investigating the cars since last April after receiving 10 complaints of sudden coolant loss on 2001-‘07 Porsche 911s.
"Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," NHTSA said.
It added: "A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted. Accordingly, this investigation is closed. The agency will monitor this issue and reserves the right to take further action if warranted by the circumstances."
There were no crashes or injuries linked to the alleged defect in any of the vehicles involved in the probe.
Porsche told federal safety regulators it identified a manufacturing quality issue with the supplier's application of adhesive to coolant pipe fittings that resulted in "elevated failure rates" in approximately 6,800 early-production 2007-'08 vehicles. The supplier has since improved adhesive application.
Edmunds says: Consumers should be aware that automakers are legally required to fix defects or recall vehicles that pose an unreasonable risk to safety — not every problem with a car.
