| Description of the problem | Jeep shifted to neutral upon startup and rolled downhill in park. (jan. 2013) note there is a recall on this issue chrysler/jeep "n23". I had not had the recall service performed. I scheduled the recall service, which was done at bosak jeep, merrillville in, in february 2013. The service is a software update to the final drive control module (fdcm). The reason for this complaint is to state that the software update performed eliminates specific functionality from the vehicle, namely 4-wheel drive low range and neutral modes (jeep being towed/transfer case disconnect). The elimination of these functionalities is creating a "black market" of owners who are swapping out the updated fdcms with pre-updated ones; and has initiated discussion of persons "hacking" the fdcm code to regain the functionalities. Http://www. Jeepforum. Com/forum/f67/n23-recall-issue-no-4-low-1561787/index168. Html my vehicle, after the update, has the "service 4wd system" light upon attempts to engage 4wd low range. Software fixes of hardware failure is specious engineering. |
