My car, the Grand Cherokee, can get OTA updates. Not sure if the 2014 Cherokee is able to get them. According to autoweek Cherokee owners could download the update themselves and install from a USB stick.[1] Chrysler issued the TSB to try and force people to come in and get an update who couldn’t or wouldn’t do it themselves.
