These cars do not drink coolant or consume coolant. If anyone is having to add coolant, the issue will eventually rear it's ugly head. Unless there is coolant on the ground or a putrid eye watering nose burning smell coming from the interior vents, the dealer will tell you everything is fine and it is normal.
If you have to add coolant, you have a leak in the system. If it is slow, the coolant usually burns off on the valley pan. When it becomes a bigger leak, you will be able to smell the burnoff.
For me, it was my turbo coolant lines leaking. Before they actually got bad enough to diagnose, I was adding coolant every other month. Since repaired, zero "consumption".
Tell the dealer your eyes and nose are burning even if they are not. This will force them to look around and replace.
