Have you experienced a louder than usual ( engine or whatever) driving sound ? Perhaps I'm overreacting but lately I have been paying close attention to the engine sounds while driving and it's louder than before. I also have been watching the RPM. I've noticed when you first start car, RMP stays at 1000. When stopping at a traffic light, it's idling between 600 to 1000

Also when it's shifting, it would shift 1st gear somewhere around 3000 RMP then 2nd and 3rd are shifted at a lower RPMs. This is kind weird to me. I thought 1 st gear is around 3000 and second 4000. It should shift will RPM gets higher.

I'm sorry I'm not explaining this well enough.

There were some discussions on why the 2017 was cheaper than other years. Maybe more problems? Dunno.

If your idle is fluctuating between 600-1000, then maybe there is a vacuum leak. Or an exhaust leak if it sounds louder?

It's a 2017 with only 45k miles. What rpm should it be idling at?

That sounds like my 2018 Sienna a week ago and now my CEL is flashing and it is not driving well at all and making strange pulsating noises. Good luck. I am sad as I came from. Honda and Chevy with high hopes. Nope. Nothing but more engine woes. 😔
