Software problems of the 2008 Jeep Grand Cherokee

My 2008 Grand Cherokee will not start at all. Dash light up but will not turn over. Battery in new. Starter tested and ok. Win recall was performed. 4wd software updates were performed. Over the past year the vehicle has had multiple no start/no crank issues. After few hours or days, it will turn over. Vehicles is always parked/not moving when this occurs. The dealer wants me to pay out of pocket for the tow for a diagnostic test. If the test does not show anything, I pay another $120 for the diag and have to pay for tow elsewhere. Jeep customer service is useless. I pay monthly payment and insurance for a driveway ornament.

Went into dealership service service center to have "n23" safety recall performed. Before n23 software update there was no problem using the 4wd-low function, afterwards the 4wd-low shift function comes up with "service 4wd" code and will not shift into 4wd-low. I discovered this while stuck in a snow drift this weekend. After researching the issue I discovered that many Jeep owners that went in for the n23 recall are having the same issue.

We are full time rvers and have towed our Jeep about 40,000 miles without any issues, until the recent recall. Nhtsa #13v75000, Chrysler n23. The very innocuous recall notice spoke of the dot requiring the recall based on a number of cases where the transfer case shifted into neutral on it's own and the vehicle rolled away, causing damage. The recall went on to say that the fix was to take it to the dealer for a software reprogramming to take care of the issue. The recall notice was very carefully and cleverly written to leave one with the impression that a software issue was the cause of the problem, and Jeep was going to fix it with the reflash of the transmission computer. This is not true. The issue is caused by the failure of hardware in the transfer case, and the ?fix? offered by Jeep is nothing more than a band aid to meet the strict letter of the demand by the NHTSA. As thousands of Jeep owners are now learning, after the recall they find themselves in a situation where the transfer case will no longer shift into neutral, or 4wd low, at all. I have personal knowledge of dozens of Jeep owners with these issues who never had a problem before the recall. This problem creates a great uncertainty among owners. We don't know if the 4wd system will work when needed, or end up stuck in neutral or 4wd low, making the vehicle unusable. While not being able to tow may not be a safety issue, I think that disabling a 4wd system that many people rely on in bad terrain or weather would be. I don't think that NHTSA has monitored this situation properly and has allowed Chrysler to commit what amounts to a fraud upon their customers. I think NHTSA needs to take another look at this issue.

The contact owns a 2008 Jeep Grand Cherokee. The contact received notification of NHTSA campaign number: 13v175000 (electrical system) and stated that the dealer informed her that the software for the recall was not available. The manufacturer was notified but could not provide a date for the parts to become available. The contact had not experienced a failure.

2008 Grand Cherokee 4x4 4. 7l flexfuel extremely sluggish on throttle demand (305 hp ???!!!), harsh transmission up/down shift and stalling at highway speeds (four occurrences within five weeks) . The dealership performed the February 2008 recall of the fcm (front control module) after being directed by the customer to do so since the serial # on the module matched the "wrongly manufactured" ones; however, the VIN search within Chrysler recall database returned empty. Evidently, the dealership owning the new vehicle at the date of the recall never performed it (as required by law) . The incident repeated after the replacement of the fcm. The dealership retrieved an abs fault code hence decided that the pcm (powertrain control module) is defective???!!! ( seven days on back order) "lifetime powertrain warranty" seems to be accomplished by ignoring of the driver's safety. The software running on the pcm should never be given the choice of immediately shutting off of the engine especially when the vehicle travels at a high rate of speed. Modern steering and braking systems are almost non-operational when there is no available assisting power.
