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.

I really hate this new update. I can’t use my phone to remote start my car. It literally is so glitchy. I turned it on and it attempted to start it but then it said one was in progress so it wouldn’t start. However that was my first time using it since the update. So I tried 3 more times and then it worked. Bur after two minutes my car cut off. It stated I only had 9% gas life in my car when I had 3/4 of a tank. It’s still saying the 9% 30 miles until empty and won’t update. It’s also telling me my hood is open my sunroof, trunk, and doors. But wait there’s more warming signs yayyyy 🙄. My coolant is low and my battery. And the battery for the Key fob. Mind you my car literally was serviced TODAY!!!! And I received a free complementary battery for my key fob. Like seriously how. There was literally nothing wrong with the app before this update months ago. I tried canceling out the app. Turning on off my phone. I tried uninstalling and reinstalling the app. Nothing works. No one wants to pay all this money for a car and you can’t even use to simple things like remote start when it’s snowing and freezing outside. This is such a inconvenience.

I am extremely frustrated! ZERO stars is more like it! I have had my 2020 GLC for 6months and after visiting the dealer and working with two MercedesMe Connect customer service reps NO ONE has been able to figure out why my app always says my engine is running rendering the app useless. They also can’t figure out why the in-car Wi-Fi (which I pay for!!!) has never worked!! I have uninstalled and reinstalled the app, Mercedes has “reset” the system multiple times. AT&T reset the system and claims the car is receiving a full signal. I was under the impression that Mercedes is top engineering but I am seriously doubting that claim when they can’t even figure out a simple software fix. I am in a populate metro area (raleigh,NC) so WiFi and cellular data is very accessible. I would love someone at Mercedes-Benz who knows what they are doing to contact me and fix this problem once and for all. I am about to sell this car and never but a Mercedes again!!!
