    Is the engine hesitating, or is the engine running fine, but feels like its slipping in gear?

    See your local friendly jeep dealer - this is a 2019 model year surely a warranty issue.

    OK after posting above I see conflicting information...

    Is this a 2019, or a 2009?
    figuring the issue is likely a older jeep, the 2009 - a guess.
    which engine and transmission.
    As mentioned does this feel like a slipping trans?
    Have you -
    checked trans fluid?
    Checked for a diagnostic code, I suggest a FREE scan at one of the auto part stores,
    >>FYI scan even if CEL is not on, Trans codes do not always set CEL to on.

    Add any maintenance history- recent repairs, trans service history, modifications etc.

    @Awrench ... professional scanner should be able to read general trans codes but for specific error a visit to the dealer was required for specific trans error code for my honda.
