Volvo XC90 Investigations (2005)
4 ODI actions on file.
- PEPE10025CLOSEDOpened 7/20/2010Central Electronic Module FailureELECTRICAL SYSTEM
Volvo acknowledged a problem affecting some subject vehicles involving water seepage into the plenum box area in the engine compartment.When this occurs water may enter into the interior / passenger compartment and track along the wiring harness for the Central Electronic Module (CEM), the device that controls many of the vehicle's electrical functions including wiper operation, lighting, and transmission operation.If the water reaches the CEM connector electrical faults may result.In response to such faults the CEM, a microprocessor controlled device, will attempt to reset by temporarily shutting down (for 100 milliseconds, or 0.1 seconds) and restarting; this effects various CEM functions including the instrument panel (IP) display, gauges, wipers and also the transmission gear (if it is in the overdrive range).During the reset owners may experience temporarily loss of the IP displays and an abnormal 'jerking' in the transmission/drivetrain.If the problem persist for 6 consecutive restart attempts, the CEM will enter a 'Limp Home' mode that disables non-essential electrical functions yet maintain safety critical functions such as low-beam headlights, low-speed wiper operation, brake lights, and non-overdrive transmission operation.Warning and error messages will also be illuminated in the IP display.Consumers reported experiencing conditions consistent with CEM resetting and the limp mode operation in their reports to both ODI and Volvo.No reports or allegations of crash or injury associated with possible CEM failures have been reported by Volvo or otherwise identified by ODI.Volvo revised the design of the wiring grommet (sealing device) and the plenum cover starting in May 2005 and October 2005 production dates respectively, the occurrence of the condition effectively ended after these changes.A technical service bulletin (TNN 37-35) has been published to diagnose and repair earlier production vehicles using the improved wiring grommet and/or new plenum cover.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 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 the circumstances.

DURING PE05-057 AND EA06-006 ODI IDENTIFIED TWO CONDITIONS INVOLVING THE POSITIVE BATTERY CABLE IN MODEL YEAR (MY) 2005 VOLVO XC90 SPORT UTILITY VEHICLES THAT COULD RESULT IN A VEHICLE FIRE:(1) POSITIVE BATTERY CABLE GROUNDING TO THE STARTER SOLENOID HOUSING; AND (2) MISPLACED JACK CRANK HANDLES UNDER THE BATTERY BRACKET AFTER BATTERY SERVICE/MAINTENANCE.DURING PE05-057 VOLVO INITIATED A SAFETY RECALL TO CORRECT THE FIRST CONDITION IN APPROXIMATELY 10,529 MY 2005 XC90 AND S80 VEHICLES EQUIPPED WITH SIX-CYLINDER ENGINES (NHTSA RECALL NO. 05V-529).IN A MAY 18, 2007 LETTER, VOLVO NOTIFIED NHTSA THAT IT WOULD BE CONDUCTING A SERVICE CAMPAIGN TO ADDRESS THE SECOND CONDITION IN APPROXIMATELY 42.211 MY 2005 XC90 VEHICLES BY INSPECTING THE JACK CRANK HANDLE FOR PROPER POSITIONING AND AFFIXING A WARNING LABEL ON THE BATTERY BRACKET TO WARN OPERATORS NOT TO PLACE THE HANDLE BETWEEN THE BATTERY AND BATTERY BRACKET (NHTSA RECALL NO. 07V-221). THE ACTIONS BY VOLVO ADDRESS BOTH CONDITIONS THAT POSE A RISK OF BATTERY CABLE FIRE IN THE SUBJECT VEHICLE POPULATION.THE AVAILABLE EVIDENCE DOES NOT INDICATE THAT THE OTHER BATTERY CABLE CONDITIONS REVIEWED DURING EA06-006 PRESENT HAVE RESULTED IN ANY FIRES IN THE SUBJECT VEHICLE POPULATION.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 IN ANY ONE OF THE ISSUES.THE AGENCY RESERVES THE RIGHT TO TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.SEE DOCUMENT FILE FOR ADDITIONAL INFORMATION REGARDING THIS RESUME.
- PEPE05064RECALLOpened 12/2/2005WINDSHIELD WIPER ARM PERFORMANCEVISIBILITY:WINDSHIELD WIPER/WASHER:LINKAGES
THE MANUFACTURER NOTIFIED NHTSA BY LETTER DATED APRIL 21, 2006, THAT A SAFETY RECALL HAS BEEN INITIATED FOR CORRECTION OF THIS PROBLEM ON CERTAIN MODEL YEAR 2003 - 2006 VOLVO XC90 VEHICLES. THE RECALL AFFECTS APPROXIMATELY 122,400 SUBJECT VEHICLES PRODUCED BETWEEN AUGUST 2002 AND OCTOBER 2005.NHTSA HAS ASSIGNED NO. 06V-144 TO THIS RECALL ACTION.THE CORRECTIVE ACTION WILL CONSIST OF REPLACING THE EXISTING WINDSHIELD WIPER ARMS WITH A NEW REINFORCED DESIGN.BASED ON THIS ACTION, THE SUBJECT PE HAS BEEN CLOSED.
- PEPE05057RECALLOpened 11/2/2005VOLVO XC90 BATTERY CABLE FAILURESELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES
THE OFFICE OF DEFECT INVESTIGATIONS OPENED A PRELIMINARY EVALUATION, PE05-057 BASED ON EARLY WARNING DATA SUBMITTED TO ODI BY VOLVO. THE DATA CONTAINED FIELD REPORTS OF THERMAL FAILURES OF THE POSITIVE BATTERY CABLE. ON NOVEMBER 17, 2005, VOLVO NOTIFIED ODI THAT IT HAD IDENTIFIED A SAFETY DEFECT IN THE POSITIVE BATTERY CABLES IN APPROXIMATELY 9,000 MY 2005 VOLVO XC90 VEHICLES WITH SIX CYLINDER ENGINES THAT COULD RESULT IN A FIRE.VOLVO RECALLED THE AFFECTED VEHICLES TO ADDRESS THE POTENTIAL GROUNDING CONDITION (NHTSA RECALL #05V-529).THERE WERE 13 COMPLAINTS, INCLUDING 4 FIRES, AND 10 WARRANTY CLAIMS RELATED TO THE CONDITION ADDRESSED BY 05V-529.DURING PE05-057, VOLVO ALSO PROVIDED ODI WITH INFORMATION REGARDING THREE OTHER ISSUES RELATED TO THE BATTERY CABLE/TERMINALS IN MY 2005 XC90 VEHICLES:1) UNDER TORQUED BATTERY CABLE ATTACHING FASTENERS TO THE STARTER ALLEGEDLY CAUSING ENGINE STALLS AND MELTED PARTS IN THE ENGINE COMPARTMENT (APPLICABLE TO V8 ENGINES ONLY).2) THE JACK HANDLE MAY BE CRITICALLY MISPOSITIONED AGAINST THE POSITIVE BATTERY CABLE/POST ALLEGEDLY CAUSING FIRES IN SOME VEHICLES (APPLICABLE TO ALL XC90 VEHICLES).3) A POTENTIAL CHAFFING CONDITION OF THE POSITIVE BATTERY CABLE TO A SHARP EDGED SHEET METAL FLANGE IN THE REAR STORAGE COMPARTMENT. (APPLICABLE TO ALL XC90 VEHICLES).THE PRELIMINARY EVALUATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA06-006) TO ASSESS THE SCOPE, FREQUENCY AND POTENTIAL SAFETY CONSEQUENCES OF EACH OF THESE ISSUES.
