| PE07027 | CHRYSLER GROUP LLC | 05/29/2007 | 08/02/2007 | ENGINE STALLING & ELECTRIC POWER LOSS | 07V291000 | |
| On july 3, 2007, daimlerchrysler corporation (dcc) submitted a defect information report to nhtsa describing a defect that could result in engine stall while driving in approximately 80,894 model year (my) 2007 jeep wrangler and dodge nitro vehicles manufactured between january 30, 2006 and january 22, 2007 (nhtsa recall 07v-291, dcc recall g25).according to dcc, the totally integrated power module (tipm) in these vehicles was programmed with software that may allow the engine to stall under certain conditions.dcc will reprogram the tipm in the recalled vehicles with revised software. odi opened pe07-027 on may 29, 2007, based on 53 complaints alleging engine stall and/or loss of electrical power in my 2007 jeep wrangler vehicles.odi was also monitoring similar complaints in my 2007 dodge nitro vehicles.dcc's analysis of complaints to dcc and nhtsa found that many described events with a momentary loss of electrical power inside the vehicle and a corresponding loss of engine power.many of the reports also indicated that the instrument cluster telltale lamps momentarily illuminated during the event. dcc's engineering analysis determined that the tipm could initiate an internal reset cycle lasting approximately 75 ms in response to error messages on the communication bus.the key on signal from the tipm to the powertrain control module (pcm) is lost during a tipm reset.if the pcm loses the key on signal for longer than 40 ms, it interprets it as the vehicle ignition being turned off and begins a power down routine.after the tipm reset, the key on signal is restored and the pcm powers back up.if the rotating components of the engine contain sufficient inertia, the vehicle may restart with no input from the operator as reported in some of the complaints.if the engine does not restart in this manner, it can be restarted by the operator.a revision to the tipm software on january 22, 2007 changed the tipm reset time to 17 ms, removing the potential for pcm power down and engine stall. odi has received 178 complaints potentially related to the alleged defect in my 2007 jeep wrangler vehicles and 52 complaints involving my 2007 dodge nitro vehicles.two of the nitro complaints allege that a crash resulted from an engine stall incident, one of which caused minor injuries to a passenger.as of june 1, 2007, dcc identified 151 wrangler complaints and 128 nitro complaints. this investigation has been closed with dcc's recall. | ||||||

| I guess i am writing with more than one issue. sorry for the inconvenience of such a long explanation but i thought long and hard before delving into this. i purchased my 2007 jeep wrangler unlimited x 4-door 2wd in october of 2006. i was one of the lucky victims that while going 70 mph, the entire jeep shut down and then restarted on it's own. this happened twice. took it in once, i got the i'm sorry look and was let go. didn't even bother with the dealership the second time and finally was lucky enough not to have a wreck before the recall was sent. within one month, not more than 1200 on the vehicle, it would not start. called tow trucks twice. each time, it took the tow truck 30-45 minutes to arrive and in that time frame, with repeated efforts, i was able to get the vehicle to start. this has not happened again for about 6 - 9 months then came february 2007. it was about 45 degrees outside and i walked out to get the mail. as i looked up at the jeep, i was stopped dead in my tracks and did not even want to face what i knew had happened. right below where the windshield starts, right above the hood, on the drivers' side was an approximate 1 crack. i went back outside 3 times thinking maybe i thought i was seeing something that wasn't really there. within one week, the crack had extended up about 1/2 and cracked horizontally about 4 inches across. so sorry again for the long, indepth letter. i just don't know what to do anymore. would really appreciate some advice. lana jackson lawton oklahoma *tr | |||

| I own a 2007 jeep wranger unlimited (4-door) yesterday i was driving on a rural highway between 60-70mph and i lost all power, the radio shut down and i looked down at my dash and all my lights lit up. i felt the engine shut down as i begun to move to the shoulder all the power came back up. i came home to tell my husband and he looked on the internet and found similar situations being reported. i called my local dealer and the dealer i purchased the car from and they both had no idea about this being an issue. my concern is will this be an ongoing issue and can it be fixed. i don't want to be driving at a fast speed to have this happen again, this cannot be safe. the dealers said they would run diagnostics but will that truly identify the issue if this has happened only once. *tr | |||

| While driving approximately 40 mph, my 2007 jeep wrangler sahara stalled while in motion. it then lost all power steering, etc. momentarily and then started itself back up without any human intervention. this has also happened previously while making a low-speed turn in which it stalled completely and i was stopped in a busy traffic area on a blind curve with traffic coming both directions. cars were coming both directions and there was almost an accident because they were avoiding me. i also had my 2 young children in the vehicle with me. i took the jeep to galeana chrysler jeep in columbia, sc twice. both times, the technicians told me there were no failure codes so there was no work that they could do. | |||
