NHTSA Defect Investigation List for the 2007 Jeep Commander
The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2007 Jeep Commander, both ongoing and closed, are listed below:
-
ENGINE STALLING NHTSA Defect Investigation #EA07007
Component: Electrical System*
Summary: On May 5, 2008, Chrysler llc (Chrysler) submitted a defect information report to NHTSA concerning an engine calibration issue that could result in engine stall in approximately 24,461 model year (MY) 2006 Jeep commander vehicles equipped with the 4.7L V-8 engine and built from February 25, 2005 through January 11, 2006. According to Chrysler, the powertrain control module (pcm) was programmed with software that may allow the engine to stall during certain operating conditions. Chrysler dealers will reprogram the pcm software in the recalled vehicles. Information provided by Chrysler during PE07-009 and EA07-007 indicated that a revised engine calibration was implemented in production effective January 12, 2006 for the MY 2006 Jeep commander vehicles equipped with 4.7L V-8 engines. ODI's analysis ofconsumer complaints, field reports and other data related to field experience with engine stalling in MY 2006 through 2007 Jeep commander vehicles equipped with 3.7L, 4.7L and 5.7L engines identified an elevated rate of stalling incidents in the MY 2006 vehicles equipped with 4.7L engines that were manufactured before the calibration change. ODI interviewed over 70 consumers who reported stalling incidents in early production MY 2006 4.7L vehicles. Information gathered from those interviews indicated that the stalling incidents were occurring at various speeds, often occurred during turns and typically occurred more than once. The interviews did not identify any concerns with restartability. Although the early MY 2006 production vehicles with 4.7L engines make up only about 15 percent of all MY 2006 through 2007 Jeep commanders built by Chrysler, they were responsible for 465 of the 854 reported stalling incidents (54%), 6 of the 12 crash incidents (50%) and the only injury claim. The stalling rate for the recalled vehicles is 1.90 percent, almost 7 times greater than the rate in the remaining population (0.28 percent). Chrysler's recall covers the vehicles with the elevated stalling rate. The remaining vehicles have relatively low rates of stalling and do not exhibit any signs of aggravating factors such as problems with restart. ODI also analyzed complaints alleging concerns with loss of lighting coincident to stalling incidents. This analysis identified seven stalling incidents where loss of exterior lighting was alleged. No specific cause was identified in these incidents and there was no discernible pattern regarding engine, vehicle production options, build range or failure trend. This investigation is closed with Chrysler's recall.

ENGINE STALL NHTSA Defect Investigation #PE07009
Component: Power Train:Automatic Transmission:Control Module (Tcm, Pcm)*
Summary: ODI has received 76 vehicle owner complaints alleging incidents of engine stall while driving in model year (MY) 2006 through 2007 Jeep commander vehicles (subject vehicles). Some of the complaints reported one or more incidents of engine stall with a simultaneous loss of some or all lighting systems, including headlamps. Two engine stalls resulted in a vehicle crash. In its response to a request for information, DaimlerChrysler corporation (DCC) indicated that it has not determined the cause of engine stalling in the subject vehicles and that it hasformed a multi-disciplinary task force to investigate the issue. This investigation has been upgraded to an engineering analysis (EA07-007) to further assess the frequency, scope and potential safety consequences of the alleged defect.

Fleet Vehicle Recall Completion Audit NHTSA Defect Investigation #AQ10001
Component: Unknown Or Other
Summary: The Agency, particularly in recent months, has been informed of incidents involving allegations of personal injury and death claimed to have been caused by safety defects and failures to conform to minimum Federal Motor Vehicle Safety Standards (FMVSS) on rental car vehicles for which a safety recall to remedy the safety defect or noncompliance had allegedly not been performed prior to the rental car company's lease of the vehicle. NHTSA understands that there is presently a petition before the federal trade commission (ftc) seeking to prohibit at least one rental car company from renting vehicles on which safety recall campaign remedies remain outstanding. The purpose of this audit query (aq) is to investigate recall remedy completion by rental car companies on the above-listed safety recall campaigns. These campaigns were chosen due to their inclusion of vehicles used in the rental market. This information is expected to provide the Agency an indication of how completely and how quickly rental car fleets, in general or individually, perform necessary recall-related repairs or other remedies on the vehicles owned and then leased for use on the roadways. This aq is opened.
