    Bought my jlu sport on Tuesday, it went to service Thursday. Smh.
    For those who care to watch you will notice the sound doesn’t start until I hit about 20 mph, it doesn’t stop until I come to a complete stop, and I’m one video I roll down the window and you can hear it is pretty loud.
    The first time it happened (Wednesday evening) it lasted less than a minute, the next time (Thursday morning) it lasted about 5 minutes during driving, the next time after that (Thursday evening) it lasted a good 15-20 minutes. It did eventually stop making the sound every time I drove it but after happening 3 times in 24 hours and getting worse I drove it to the dealer.
    So what are your thoughts? It’s bone stock.

    That’s not a normal sound. Take it to the dealer.

    It’s at the dealer, they can’t repeat the sound so I sent them numerous videos and told them precisely how to make it happen.
    I guess the frustration comes from the fact that my new wrangler has been at the dealership for 3 days and I’m my possession for only 2 days.

    My previous Jeep had a squeal kind of like that once and the mechanics found a pebble stuck near the rotor causing it.

    It’s similar to a pebble or bent dust shield but the sound doesn’t start until about 20 mph and it goes away after some driving.

    My JLU made the same sound when I first got it end of July on drive home from dealer. Sounds crazy but tightening gas cap fixed ironically until today. The sound has returned and tightening doesn’t fix it this time

    Wild guess... Maybe it is the electric steering pump / assist? Since it doesn't stop until you come to a complete stop, does it change pitch if you were to slow down, turn into a parking lot or road with no traffic and turn the steering wheel hard to the left and right?

    I feel we may be on to something here. Is there a speed that the electric assist kicks on at?

    I spoke to my salesman, two sales managers and the service manager tonight.
    I’ve been told to call in for a conference call at 10:30 tomorrow morning. Service manager agrees that it sounds like a bearing coming apart.
    It’s been at the dealership 4 days and they have made 0 progress. Even on the seat latch they said they would fix today. I’ve been lied to at least twice that I’ve caught and called them out on but I’m really trying to keep cool and ask them to see things from my point of view.
    We will see what happens.

    After a bunch of back and forth we may possibly have a resolution- fingers crossed here

    The rear pinion dust sleeve came loose. Hoping we may have a fix if you want to check yours.

    Hi gregoryd3,
    Send us a private message if you decide to have your dealer look into this so we can have this documented and add some extra assistance while your jeep is at the dealer.

    We're glad to hear that your dealer may have found a solution, jruss. If you find that this does not eliminate the sound, please send us a private message so we can have a case escalated for further investigation.

    Lydia
    Jeep Social Care Specialist
