One problem related to engine funny noise has been reported for the 2012 Jeep Patriot. The most recently reported issues are listed below.
While driving my 2012 Jeep Patriot sport 4x4 down the autobahn at around 120km(74 mph) my Jeep started making a deep whirling/humming sound. While accelerating it is a low deep sounding whirling/humming sound, while decelerating the whirling/humming sound becomes louder deep sounding whirling/humming. I tried calling the Jeep dealership here in germany but was basically told they could not be of any help do to my Jeep being american spec. Also, I find it absurd that my Jeep has recalls and I was never informed and of course I've been told that I cannot get them fixed over here.
