I have a new to me 2018 Dodge Grand Caravan with almost 50,000 miles. I’ve had it about 2 months and pretty much from the get-go heard a ringing sound when I decelerated and got around 20 mph. It is not the brakes. It is the whole time I am going from 20-16 mph and also when I am more or less coasting when approaching a street or driveway at that speed.
I took it back to the dealer after about 3 weeks and they couldn’t find anything wrong.
Well, either it is getting worse or I am just paying closer attention, but now I can ‘sometimes’ hear it around 10 mph–when speeding up or slowing down. It sounds louder at 20mph–but again, maybe I am just paying better attention. I do hear the same around 30 mph but it is rare.
Took it to dealer today with all this down on paper. After looking it over and driving it, they said it is the gears in the transmission but there is nothing wrong with the integrity of the gears. It is the way the gears are cut for that specific transmission. They drove a new Grand Caravan with only 24 miles and it has the same sound, just quieter. They said the noise increases as the gears ‘mesh to each other.’ The noise ‘shouldn’t’ get any louder than it is.
This not an annoying sound but I am thinking transmission problems = $$$$$$$$. They did offer to replace the gears but said the noise would eventually come back like it is now.
Does this sound right? Should I tell them to replace the gears? It is still under warranty but I am hesitant to tell them to tear into something if it’s not necessary.
Thanks for any advice you can share.
