Recall #07V192000

** This defect investigation is filed under 2 related vehicle components.
2005 DODGE GRAND CARAVAN -- DaimlerChrysler (DCC) will replace the frame rail-mounted front air bag crash sensors in approximately 270,958 MY 2005 DaimlerChrysler minivans (NHTSA recall no. 07V-192).these vehicles are equipped with front crash sensors with brass bushings and were built between April 24, 2003 and February 2, 2005.this action covers vehicles originally sold, or currently registered, in 27 states (Alaska, Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Nebraska, New Hampshire, New Jersey, New York, North Dakota, Ohio, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, West Virginia and Wisconsin) and the District of Columbia.vehicles sold or currently registered outside of these states, approximately 133,128 MY 2005 minivans, will receive a lifetime warranty on the front crash sensors.although these vehicles use the same brass bushing sensors and were built during the same period as the ones described above, they experience significantly lower failure rates because of reduced road salt exposure.DCC will also provide written notification to all affected vehicle owners.NHTSA and DCC differ regarding the significance and impact of the defect, but in the interest of remedying the affected vehicles expeditiously and to avoid a protracted dispute, DCC is implementing steps to replace the subject components.based on these actions, the Agency has decided that further use of its 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 no safety-related defect exists in the subject vehicles.the Agency will monitor the issue and reserves the right to take further action if warranted by the circumstances.select document search for additional information.

NHTSA Defect Investigation #PE05061

FRONT AIR BAG CRASH SENSOR FAILURE: Air Bags:Frontal**

CLOSED

no recall issued

** This defect investigation is filed under 2 related vehicle components.
2005 DODGE GRAND CARAVAN -- The model year (MY) 2005 DaimlerChrysler (DC) minivans have the new advanced frontal air bag systems with two front crash sensors mounted on the frame rails behind the front bumper and a main crash sensor inside the air bag control module mounted in the passenger compartment.according to DC, the front crash sensors are designed to optimize detection of frontal offset and angular crashes.the advanced air bag system offers different levels of air bag inflation based on input from the crash sensors.this investigation revealed that the front crash sensors can corrode from water entering the sensor assembly.DC is still investigating all potential root causes of sensor failures.a corroded sensor can set a fault code, illuminate the air bag warning lamp, and become disabled.it appears that failure of one or both front crash sensors can potentially result in no/late deployment of frontal air bags and non-deployment of driver's higher inflation levels in certain frontal crashes.it should be noted that occupants of vehicles involved in a crash may not be aware of late or improperly reduced level of air bag inflation and thus field reporting of such events may be suppressed.this preliminary evaluation has been upgraded to an engineering analysis (EA06-003) for further investigation of MY 2005 (and 2006) DC minivans.note: Total number of ODI and manufacturer complaints includes some duplicate reports. Investigation was initiated on November 10 2005. Closed on March 08 2006. For detailed information & supporting documents, see the official NHTSA page concerning investigation #PE05061 »
