Hi - I have a 2017 v6 durango and very sporadically when I push the start button, it takes a while for it to "connect" and start up fully. All power is on when I press the start button, it's like it doesn't have full power when trying to turn on. It makes noises like its trying to connect and then it does. Maybe 8 seconds or less. It was only doing it a few times, now its at least once a day, all different times - no rhyme or reason of when it happens. Had the starter and battery test, perfect. It has 54,000 miles. Just had the oil changed this week. WHAT COULD IT BE? I dropped it off at Dodge Service, of course, didn't happen when there, so they couldn't find anything. It's doing it daily now; no lights are on either. I just need some direction of where to start looking or what to do.

THANKS! :)

As long as it's intermittent, you're going to have a rough time tracking it down. My THEORY would be a loose, or corroded connection someplace, making/breaking contact. And the key-word there is 'Someplace'.
At this point, if mine, I would check the main buss connector at the ECM. Also in the "power distribution center" (fancy name for the fuse box) under the hood, I would check the following fuses for loosness, signs of burning/melting, or corroded fuse blades;
F-07, (30A pink fuse, serving the Starter Motor Solenoid.
F-51 (15A Blue fuse, for Ignition Switch/ Wireless Control Module/Keyless Entry Module).
Nothing found, I would start looking around for other obvious signs of "chewing"/chafing/burning/melting along the harness. I've heard of common issues with squirrels and other rodents being attracted to the soy-based wire insulation car makers are now using (they EAT the wires ns!) along with the fact that they like to nest in warm places this time of year.. Wouldn't surprise me one bit, if you find a "nest" under the PDC, ECM, top shroud, or other hiding place.
EDIT: Pic of the PDC fuses.

Must be something in the water down there in Houston lol! While you Houstonites are at it, send us Ohioans some danged heat! We have our usual February temps in the 20's, along with wind chills in the teens this morning. :0(

Good luck on the starting issues.

Same issue in Houston with a 2017 Durango. It started doing it in the fall sporadically and then it seemed to stop for the most part. Now that temperatures have warmed up some it is struggling to start everyday, sometimes multiple times a day. What in the heck is wrong with Durangos? Been a great car so far until this issue. What dealership did you buy from? Mine was bought at AutoNation in Spring. Wonder if they are from the same family.

Do you have auto start/stop? Did they test both the primary battery and the start/stop battery, which should be located under your passenger seat? I'm not sure if the smaller start/stop battery also performs the duty of cold-starting, but a bad battery, corroded connections at the battery, or bad ground at the battery may be causing this issue.

I do have auto start. I’m going to have the batteries checked now. Hoping that fixes the issue. I’ll keep you posted. Doing an oil change as I type this.

I took my Durango to a mechanic today. It is a programming issue. Its the Map reading which apparently has to do with the barometric pressure, makes sense since there appears to be a big problem in Houston. The reading should be between 8-9 HG but mine was reading at 72 HG. I called the dealership and unfortunately I still have to pay their diagnostic fee since there is no recall on my vehicle. If it a programming issue I will be contacting Chrysler.
