2023 Mercedes ESQ SUV 580 ● 2021 Volvo XC40 Recharge
I own a Volvo XC40 electric along with a EQS SUV 580. Even though my EQS has never had that warning, my Volvo did a few weeks ago. The Volvo dealership topped it off for me and I was out of there in a half hour.

I was getting the same thing.
It happened once before during a fairly aggressive right turn (on ramp to highway) and I didn't think much of it then.
flash forward, getting the same message starting about 2 weeks ago. No smell of coolant or noticeable leaks on the ground. was due for service so I added a cup of water each time (happened 2 or 3 times) to make the warning go away until my service apt. last Thursday the heating system valve (something on the firewall that directs heat or something) failed and dumped all the coolant. was able to get off the road and towed to the shop. $76 part but a couple hours labor. not the worst thing.

EQS 450+ SUV 2024
I experienced this just a few days after taking delivery of my 2024 EQS 450+ whenever I did a prolonged acceleration. I wasn't ready for a long service appointment for such a new car, so I told them to just top it off. I knew the problem will come back soon if it was an actual leak. After 11k miles the error came back so this time they did a full diagnosis and leak test. They found a crack on one of the reservoir tanks. The car spent a week at the dealership for the replacement due to parts shipping from Germany. All covered under warranty. Haven't experienced that issue since then.
