One problem related to software has been reported for the 2015 Jeep Patriot. The most recently reported issues are listed below.
A circuit wire corroded and shorted the tipm. This happened at home. The car was stored in the garage. The car wouldn't start. I had it towed to the dealership. When connected to the dealer diagnostics it showed no error codes. When the mechanic replaced the wire at the dealership service shop the starter ran non stop without the key in the ignition. I am unaware if the car starter also came on without the key when I was not near the vehicle. This vehicle does not have remote start. It is driven on paved rides and stored in a garage. I am the second owner. Less than two weeks prior to this shorted tipm the vehicle was serviced at the same dealer for a factory recall to change the catalytic converter and to do a computer software update.
