I have a visual low coolant level in the tank not the sensor that needs topping off.

 

My vehicle has the same issue. On my 2nd day of ownership, I got the low coolant warning. It was right at the max level and I just added a few drops of coolant and then I stopped having the issue. But the warnings started up again this week (I now have 12,500+ miles on it) and when the engine is cold in the morning, the level is at high. The warning only stays on for about 5 minutes when driving and then goes away. I think it tends to happen when on an incline.

This has happened to me twice. Both with the truck fully hot but also on an incline. It’s going into the dealership on the 26th for remediation. When they’ll also look at some weird rattling/buzzing noise coming from the Qi charger under the armrest.

 

We had this issue as well within the first 300 miles. This has been constant once the motor was at normal operation temperatures. The dealer replace the coolant reservoir which houses the sensor. the part number is new indicating that JLR has redesigned the part. The problem is now fixed and we have not had this error message since.
