AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE Investigation
The investigation was opened based on reports of frontal air bag inadvertent deployments (ABIDs) on model year (MY) 2002-2003 Jeep Liberty vehicles.Data provided by Chrysler indicate that the air bag squib filter circuitry inside the Occupant Restraint Control (ORC) module can degrade and result in an inadvertent air bag deployment, without a crash or impact, while the vehicle is being operated on the roadway.As of Oct. 04, 2012, ODI is aware of 131 frontal ABIDs on the Jeep Liberty vehicles resulting in 62 injuries consisting of burns, cuts and bruises to the upper body region.There were no reports of loss of vehicle control or vehicle crashes.Some owners noted that the air bag warning light (ABL) and/or chime had activated just seconds prior to the air bag deployment, while others stated that they did not observe any prior ABL illumination.Chrysler's analysis found there were no reports of ABID on Liberty vehicles build after March 28, 2003, a date which coincides with a filter circuit design change in the ORC module.The Jeep Grand Cherokee and Dodge Viper were identified as having the same basic circuit.ODI is aware of 61 frontal ABIDs with 31 injuries on the Grand Cherokee and none on the Dodge Viper.In its Nov. 07, 2012 letter (12V-527), Chrysler announced plans to recall 744,822 Jeep Vehicles (MY02-03 Liberty through 03/28/03 and MY02-04 Grand Cherokee through 5/23/03).The remedy consists of installing an in-line jumper harness with an integrated squib circuit electrical filter.In addition, in Feb 05, 2013 letter (13V-040), Chrysler added the MY03-04 Dodge Viper (through 6/30/04) with a similar remedy, bringing the total number of recalled vehicles to 748,482.During the investigation ODI contacted the ORC module supplier (TRW) to determine the usage of this circuitry in other manufacturers? vehicles.As a result, ODI sent peer Information Request (IR) letters to five other manufactures.Toyota's response identified 72 frontal ABIDs resulting in 31 injuries.The rate and failure mode/trend were consistent with the subject defective issue as reported by Chrysler.In a Jan. 30, 2013 letter (13V-029), Toyota announced plans to recall 897,709 MY2003-2004 Corolla/Matrix and Pontiac Vibe vehicles and will utilize a similar remedy to that of Chrysler consisting of adding an in-line noise filter to its air bag wire harness.Honda's IR response reported 126 unique ABIDs for both frontal, side impact and/or side curtain air bag deployments across 4 models and 800k vehicles.However upon further review, no more than 25 of the reports appeared to be frontal ABIDs.The remaining involved less aggressive non-frontal ABIDs mainly stemming from side sensors that trigger side and/or side curtain air bags upon undercarriage debris strike or heavy door slams.The Honda rates are lower than those from the recalled Liberty and Toyota models, and with the exception of the MY 2002-2003 Odyssey, the other Honda models' failure mode/trend was also less severe.ODI will continueto monitor the affected Honda models.There were no reports of ABIDs from the other three peer manufacturers.It should be noted that since the October 2012 data collection date, ODI has received 4 additional Jeep Liberty and 2 Jeep Grand Cherokee reports for frontal ABIDs with two reports alleging loss of vehicle control and crashes. To date, the ORC modules from the two crash vehicles have not been available for detailed analysis by Chrysler or ODI, so the cause of the ABIDs cannot be confirmed at this time.Accordingly the investigation is closed.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAI

AIR BAGS Investigation
Based on analysis of Chrysler's response, and including ODI's consumer complaints, ODI has identified 87 reports of air bag inadvertent deployment incidents resulting in 50 alleged injuries.The injuries consists of burn/cuts and bruises to the upper body region.Forty-two (42) of the 87 incidents involved the driver frontal air bag, and the remaining 45 incidents involved both the driver and passenger frontal air bags inadvertently deploying without a crash.These incidents occurred both at vehicle startup or while the vehicle is being operated on the roadway.Some owners noted that the air bag warning light had illuminated, or had intermittently illuminated, and that this occurred just prior to the air bag deployment, while others stated they did not observe any illumination of the air bag light. Inspection of the Occupant Restraint Control (ORC) module conducted by Chrysler indicates that an internal electronic circuit (an ASIC chip) which controls air bag deployment fails due to an electrical over stress (EOS) condition possibly caused by a transient voltage spike.Chrysler is in the process of identifying potential root causes of the component failure and/or a source for the electrical over stress.In addition, Chrysler noted that there have been no reports of inadvertent air bag deployment in vehicles manufactured after a March 19, 2003 production date.However, Chrysler had not identified a component or other change that would explain why the inadvertent deployments ceased. Accordingly, this investigation has been upgraded to an Engineering Analysis (EA12-001) to further study the alleged defect and its consequences.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers: 10435710 10429579 10429306 10428411 10407276 10399551 10335637 10283484 10249231 10166706 10055405

SUSPENSION:FRONT:CONTROL ARM:UPPER BALL JOINT Investigation
ON APRIL 7, 2009, CHRYSLER LLC SUBMITTED TO ODI A DEFECT INFORMATION REPORT INDICATING THAT IT WOULD RECALL APPROXIMATELY 42,469 MODEL YEAR 2002 THROUGH 2003 JEEP LIBERTY VEHICLES TO REMEDY A DEFECT THAT CAN RESULT IN UPPER BALL JOINT SEPARATION WHILE DRIVING (09V-119).THE AFFECTED VEHICLES WERE BUILT FROM MAY 2002 THROUGH SEPTEMBER 2002 AND ORIGINALLY SOLD OR CURRENTLY REGISTERED IN CONNECTICUT, DELAWARE, DISTRICT OF COLUMBIA, KENTUCKY, ILLINOIS, INDIANA, IOWA, MAINE, MARYLAND, MASSACHUSETTS, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, VIRGINIA, WEST VIRGINIA AND WISCONSIN.ACCORDING TO CHRYSLER, THE FRONT SUSPENSION UPPER CONTROL ARM BALL JOINT MAY EXPERIENCE A LOSS OF LUBRICATION WHICH CAN LEAD TO CORROSION, ACCELERATED WEAR, AND POSSIBLE SEPARATION WHILE DRIVING. CHRYSLER'S RECALL PROCEDURE INSTRUCTS DEALERS TO REPLACE THE FRONT UPPER CONTROL ARM ASSEMBLIES ON ALL AFFECTED VEHICLES. ALTHOUGH THE SPECIFIC CAUSE FOR THE DEFECT IN THE RECALLED PRODUCTION RANGE HAS NOT BEEN DETERMINED, ODI'S ANALYSIS OF UPPER BALL JOINT SEPARATIONS BY VEHICLE BUILD DATE SHOWS A CLEARLY DEFINED AND SIGNIFICANT SPIKE IN THE RATE OF SEPARATION DURING THE FIVE MONTH PRODUCTION RANGE COVERED BY 09V-119, WHICH ACCOUNTS FOR ONLY 11 PERCENT OF SUBJECT VEHICLE PRODUCTION BUT APPROXIMATELY 70 PERCENT OF SEPARATION INCIDENTS.SEVENTY-FOUR (74) OF THE UPPER BALL JOINT SEPARATION INCIDENTS IDENTIFIED BY ODI OCCURRED IN VEHICLES PRODUCED IN THE RECALL MONTHS, RESULTING IN A SEPARATION RATE OF 174 PER 100,000 VEHICLES.THE SEPARATION RATE IN THE REMAINING SUBJECT VEHICLE POPULATION IS SIGNIFICANTLY LOWER, AT 9 INCIDENTS PER 100,000 VEHICLES.AT THIS TIME, THE DATA DO NOT SHOW A DEFECT TREND IN THE SUBJECT VEHICLES BUILT OUTSIDE THE RECALL RANGE AFTER APPROXIMATELY 6-8 YEARS IN SERVICE. THIS ENGINEERING ANALYSIS IS CLOSED.
