13 days into owning my brand new GLS 450, I got an alert that my coolant was low (this is just after it stalled while I was still moving). Yep, coolant is low. It’s next to impossible to find what coolant to put in bouncing from the manual, to this reference over to that one all telling you that you can’t put non-spec coolant in, but none telling you the right coolant. Find the coolant and go 20 miles from my home and the check engine light comes on. I tried to find any information about the alert on the app or online log in and NOTHING! I can see my tire pressure and on EVERY screen that my car is unlocked, but ABSOLUTELY nothing about the check engine alert I’m getting. Never thought I’d say this... I’d like my GMC back. The information your car sends is invaluable. This app is only good to lock and unlock your car. Otherwise it’s a web with 3 basic points of information. Tire pressure, lock status and if any window or door is open. Useless, useless.And we did contact the dealer. Service was closed - they don’t work Saturday- and 7 hours later the sales person sent a pic of the Mercedes log I’d coolant you can only get by ordering online and having 2-4 day delivery. Look forward to the update on the in- car software. Would be helpful to not be notified everytime someone opens the door that our third row or second row seat is folded down. YES, I know. I put it down on purpose.
Hi dstaffor, Thank you for your feedback! If you ever have vehicle specific questions like what coolant to use, please contact your local Mercedes-Benz dealer. For the check engine light, this is a limitation with the in-vehicle software that we are currently trying to improve.Thank you,Mercedes me connect team
