I have about 2200 miles on my new SXT. I have already took it to the dealership service department complaining about a few things and wanted to see if these are "normal" as they say.

Idle: The RPM's are steady at idle but there in still a shaking I can feel when idling, sometimes the idle feels like it dips (misses) but the RPM is steady. It seems more like an engine mount but I had them check that. They said they checked my idle and its fine, but it shakes more at idle that my old trailblazer with 100k on the odometer. I feel with a new car I shouldn't even be able to tell its running, at least with a V6 made for minivans and sedans. I had them check all my ground wires, I did not mention the manifold bolt thing as I read its only on the HEMI's.

Accel Delay: This is worse when on cold start, but there is major hesitation from the time i press the pedal to the car moving. This process is not smooth, first its no response then it jerks forward. I was reading around and a lot of people say its because of the economy programming for the transmission but this happens in sport mode as well.

If this is normal, then I will leave it alone. If this does not sound normal, what should I have the service department look for when I take it back? This forum has an amazing community and I am appreciative of any responses.

Doesn't sound normal to me. My 2016 SXT Plus idles smooth. I can't tell it's running sometimes. Gas pedal is responsive. Not perfect but close. I'd guess they need to do some reprogramming first and see if that fixes it.

BTW, when I hear the words "functioning as designed" and "runs normal", I usually look for another dealership.

I agree with above. There is some talk about the A8 when it's cold not shifting smoothly, but I haven't witnessed it. I can hear my car idling with my exhaust, but before the exhaust, it was very quiet, and even now I feel no vibration or roughness when it's idling. Just over 4500 on mine. A Guy

Hi Texredner,

Congrats on your new vehicle! If you decide to visit your local dealership for further diagnosis I'd be happy to offer assistance if needed. Just PM our page with your VIN and let me know.

I have 2016 SXT with 7K miles and I have exact same behavior. At idle, I can feel the car shaking a bit. Not much but noticeable. Also, the acceleration when floored comes after a bit hesitation (this is in normal mode, haven't tried sport mode yet).

Both of these "issues" seem normal to me. My Challenger sometimes has a noticeable idle vibration, usually when it's cold outside. Other times it's perfectly smooth.


The accel delay is especially pronounced if you don't come to a complete stop. The A8 transmission will not downshift into 1st gear until you are almost completely stopped. So if you are still moving at 2-3mph and then accelerate, the car will hesitate for a second while it downshifts from 2nd into 1st gear before it will begin accelerating.

I haven't noticed if there is a change when engine is warmed up. I usually feel the vibrations when leaving garage and when I am entering destination address into navigation while the engine is running.

The delay in acceleration is present at all speeds and all gears. Even at highway speeds, the car will take its time to start accelerating. Kinda weird in naturally aspirated engine. The delay is gone when I switch to sport mode. I guess that's the easy way for Dodge to give us a bit of a sports feel. With the delay removed, the car feels snappier.

I've got 7,000 miles on my 2016 SXT V-6 and it idles smooth - even on a cold start. There is a slight delay in throttle pedal response in normal mode due to the "fly by wire" digital throttle system, but in Sport Mode it's pretty snappy. The A8 trans does shift a bit more firmly for the first 5-10 minutes after first starting out after a cold start.

I have a little over 19,000 miles on my 2016 SXT Plus and I can't tell when it's idling. I would take Dodge Cares offer of helping you find a dealer to look into it. What you are describing doesn't sound normal to me. At least it not been my experience with my 2016 SXT Plus.

If you haven't had it looked at yet you might try using premium fuel and see if you feel any difference. I've noticed a sharper throttle response when using 91 octane fuel. But you shouldn't have to so I would still take it in with the help of Dodge Cares.

Anyone ever try this product? This looks like it would solve throttle delay problems.
https://www.pedalcommander.com/prod...-v6-305-hp-2008-throttle-response-controller/

I've had my eye on that device and plan to order one in a week or so. Those who have used it say it really wakes up the way the car drives and responds to the throttle - especially with the V-6's like we have. Our V-6 cars don't have a lot of torque down low and this would seem to fit the bill in making it a lot snappier down in the lower rpm range. Money back guarantee is a plus too - try it and if you don't like it you can return it within 14 days of delivery minus a 10% restock charge. I'm going to make sure I find a discount code too before I order.

I still believe the OP needs to have his problems checked out further. Maybe take it to another dealer for a second opinion? I wonder if the adaptive driveline system is playing into this in some way? What kind of driving is he normally involved with (heavy stop and go traffic or ???). There's a fuse you can pull to set the adaptives back to default - I know its Fuse #31 for 2015+ models for the engine adaptives reset (I've done that one once), but not sure which fuse to pull for trans adaptives reset.

I was going to get one but a few of the Amazon reviews concerned me. Apparently, if the unit fails you loose all throttle control. Nothing happens when you hit the gas. So I was going to do a bit more research first. But from all the other reviews on various models, this item makes a huge difference.
