Two problems related to software have been reported for the 2014 Jeep Wrangler. The most recently reported issues are listed below.
Went to start the vehicle and when I went to turn the key the Jeep lost power to all electrical systems. After waiting for a bit the system "rebooted" and I was able to start the vehicle and go. However, this keeps happening sometimes multiple times a day and sometimes once per week. We have taken it to the dealership for repairs and they updated the wcm software to version 0. 20 and the problem still exists. We have also had episodes of the electrical systems going out while driving causing the engine to sputter, instrument panel goes dark, radio shuts off, ac fans shut off, etc. .
On July 3, 2014, the vehicle lost engine power while I was driving during a 150-mile road trip. Upon coasting for a short distance, engine power restored, and I was able to accelerate and continue driving without further trouble that day. I did not take the vehicle to the dealer for repair because I assumed it was an isolated episode. However, on July 22, 2014, I again had trouble while on another 300-mile round-trip road trip. During the return drive, the vehicle lost engine power at least six times both on the interstate and on local roads. Each time, I had to coast to the side of the road so as to not block the flow of traffic. After a short time, about 30 seconds, engine power restored, and I was again able to accelerate and continue on with my trip. I took the vehicle in to the dealer on July 23, 2014, where it was kept until July 28, 2014. The technicians were unable to reproduce the issue, and the problem could not be identified. Software updates were run in an attempt to correct the problem. I again had trouble with the vehicle on August 18, 2014, when driving a 400-mile round-trip road trip. During the drive, the vehicle lost engine power five times on the interstate, at speeds up to 70 miles per hour. Upon the fifth episode that day, I took the vehicle to the closest dealer for immediate attention, as I feared I would cause an accident by losing engine power while driving on a busy interstate. The service department was unable to reproduce the issue, but the technician stated that he ¿saw signs� of the problem I described during his evaluative drive. The vehicle was released to me and I was told to take it back to the usual dealer the following day for a more comprehensive evaluation. Upon driving it for over 100 miles, the service department has been unable to replicate the problem and, thus, again has been unable to identify and repair the issue.
