One problem related to loud engine noise has been reported for the 2017 Jeep Compass. The most recently reported issues are listed below.
I purchased my 2017 Jeep Compass trail hawk brand new, my production date is April 26, 2017. I have had endless issues w/ this vehicle, I have owned other Jeeps and never had these issues. It started w/ my radio making this crazy indescribably loud sound along w/ freezing the screen. Turning off the radio would not stop the sound, not even turning off the entire vehicle would stop the sound. Serv dept could never replicate, I brought it in one time when radio was on a non-existent phone call and acting up. They took my car and turned it off, next day told me they couldn't replicate. I demanded that the girl who took my car in and saw what was going on speak with the tech to explain what she saw. They agreed to order me a new radio. Additionally I began having issues w/ Jeep throwing on random dash indicator lights and not starting. Tcm pin was spreading and causing indicators b battery controlling stop/start tested bad. They replaced. I had already replaced my a battery a day or so before. Damage wires found at fuse box (they blamed me) I have made zero mods to car or even lifted the hood myself. Bcm replaced. I had issue w/ engine cutting off while driving in road & pulling ebrake before I'm due for oil change. Had oil consumption test done and they say it's fine, this is because Chrysler makes up the consumption standard. So you will always be "fine. " this it to prevent you from getting to compression test. I go in many times for this same issue. Eventually, I demand with fca that they allow compression test and replace my engine when they discover it's due to oil consump. Tech reports oil low, sprk plug cyl 3 is oil fouled, compress. Test done air is felt from oil fill, bore scope of cyl 3 walls are scored and have oil on them. Fca approves new engine for me. After new eng. I drive 13 mi eng is over heating. T-stat clamp replaced. Do not give up & document well!.
