Check engine light - code p0128

I received my GLC 250 about 45 days ago and the CHECK ENGINE LIGHT has come up 6 times always with code P0128 Coolant Thermostat (Coolant temperature below thermostat regulating temperature)
They have changed the thermostat, updated the software in the car, and are now performing more test to make sure the problem is solved.
Anyone else experiencing something similar? Would appreciate any info.

Someone else on the forums had this same issue I think. It isn't something that's common but it's not a rare occasion either if that makes any sense. Once it was covered under warranty, you should be good to go :)
