Sal, thank you for the email greeting. I purchased a 2021 Telluride EX a month ago and have been really impressed with your Forum which has answered many of the questions I've had. as well as seeing the many accessories that are available. Today I decided to join the Forum with a question which I've now posted regarding the ISG operation. If it's already been addressed previously then I've apparently missed seeing it. Thank you for putting this site together.
