I’ve had it for a little over a month and there’s only about 800 miles left on the power train warranty.  

I’ve had it for a little over a month 

I just bought a 2016 Dodge Journey with a 6 speed transmission.  It the awd sxt  but anyway when I’m just cruising around town (low speeds) and I coast time a stop it sometimes feels like I’m going over rumble strips and it sorta feels like it’s stalling as well.  There are no active recalls on it.  I was just wondering if anyone had the same issue have any tips or advice.  Also if I get on it on an on ramp or something it whines sounds like a super charger not sure why it does that or is that because it’s awd? Idk any help would be appreciated.  Thanks
