Investigation Summary
On October 14, 2011, Lotus Cars USA Inc. notified the Office of Defects Investigation (ODI) that it will conduct a safety recall (11V-510) to address concerns with engine oil cooler lines detaching from its crimped fitting on MY 2005-2006 Lotus Elise vehicles.In its 573 report to ODI, Lotus indicated that they have identified instances where the oil cooler lines would detach from their fittings.Lotus attributes this condition to a majority of single supplier affected parts built from June 2004 to November 2006.Lotus states that the cause of the failure is an inadequate process by which the hose is crimped into its fitting by the supplier.In October 2006 the supplier implemented an improved crimping process.Reports indicated that this condition can occur while driving or while the vehicle is stationary with the engine running.In cases where the failure occurred while driving, oil would be expelled under pressure and could come into contact with the tires and or brake friction surfaces, potentially causing a loss of braking or vehicle control. One crash and one vehicle fire were also reported with no injuries.Additionally Lotus indicated that the same condition can occur in MY 2005-2006 Exige vehicles as well. These vehicles are also included in the recall.The action taken by Lotus is sufficient to resolve the issues raised by this investigation.This investigation is therefore closed.
