Hi ape,
The final official reply from the FCA was that its due to the ESS feature,and is inherant to the design.
I think its cause by the heavy duty starter motor,nothing can be done.
**Update**
Got a call from the dealership,they said they recieved an email from the FCA stating that the squeal is a characteristic of the engine,I should be recieving a copy.
What a characteristic!!!
Hi there,I have the same issue on my 2018 durango,had the starter and torque converter replaced,nil help.
Did you manage to dissable the ESS and has the squeal gone away?
Hey there,I have 2018 durango with a pentastar fitted,I had the FCA involved and the dealership replaced the starter but it didnt help,and later they replaced the torque converter but the squeal and the thump still comes intermitently.
Maybe if more people raise this matter to FCA they will...
My dodge durango 2018 fitted with a pentastar 3.6 does the same squeal and thump,the dealership here in bahrain replaced the startor motor and the torque converter,but the noise is still there 3000 km later.
This is the sound of my car
