Investigation of Engine Compartment Fire

Subject: Engine compartment fire
Components covered:
  • Steering electric power assist system
  • Steering hydraulic power assist system
  • Steering hydraulic power assist hose, piping, and connections
  • Steering power assist pump
Investigations Summary: This investigation was opened on Aug. 14, 2007. It was closed on Aug. 13, 2008. The office of defects investigation (odi) analyzed consumer complaints to BMW of north America, LLC (BMW)and to odi that alleged failures of the electrohydraulic power steering (ehps) used in model year 2002 through 2003 Mini cooper vehicles. The analysis determined that 43 of the 52 (83%) reports were related to allegations of power steering loss and 9 (17%) were related to allegations of engine compartment fires. Although some of the reports alleging fires note small flames were visible in the engine compartment, analysis of the damage caused by these failures indicates that even the most severe incidents were limited to localized thermal damage to the ehps electrical connections and wiring insulation. None of the complaints alleging loss of power assisted steering indicated that the increased effort resulted in a crash or loss of vehicle control. A safety-related defect trend 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 closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency will monitor this issue and reserves the right to take further action if warranted by circumstances. See document file for additional information regarding this resume.
