Normal vibrations?

[24stx87]

I have a 2.7 stx with under 1000 miles. I have 2 vibrations and I just wanted to see how “normal” they were and/or normal break in period items.

1- idle is “rough”. I read it’s pretty common for a rougher idle with the AC on. I feel it in my seats and it’s worst when in park than drive. I don’t feel it when I’m moving at all. With the AC off, it’s like almost entirely non existent. Rpm’s don’t jump around much and no codes.

2- a throttle pedal vibration around 45 mph. It’s really just that. Starts maybe lower 40s mph and stops upper 40s. It’ll do it in any gear I select (5,6,7,8) and any drive mode. Smooth roads are more noticeable, but any road will do it. Seems like it’s non existent in colder temps. I’ve only had the truck in summer but on cool mornings (under 70 degrees) I don’t feel it. No one else can feel it in the truck, only the throttle has the sensation.

anyone else have both of these items? I can’t really pinpoint what they could be because more major issues would throw codes and other people would feel the sensation if it was a wheel or driveshaft balance issue.

thanks!!!

I forgot to mention, I tried premium gas and there’s no difference and I changed the tire pressure, no difference.

I never had either of those two scenarios during my entire ownership. It’s been buttery smooth.

Hi there! Would you send us a private message with your VIN and dealership name and location? I’d like to look into this concern on my end.

I am driving a '24 STX service loaner with the 2.7 and it idles like garbage with the A/C on. I can't stand how rough it runs at a stop light and have to turn the A/C off during that time. Something is wrong with this engine.

Not normal.
