I got my certified pre-owned QX30 with 23,000 miles on it June of 2021! This car is a dream to drive and the cert pre-owned warranty is awesome too! I've had trouble with coolant issues which is how I found this forum. The dealer obviously has paid for every visit ( about to going in again 3rd time for coolant issues) and given me a loaner (which is one more reason to love INFINITI) but its just been frustrating having that coolant light come on constantly

You write everywhere about problems with the coolant.
What the problem is what happened. How did the dealer solve the problem?

First he put in a new reservoir, then fixed a leaking hose..lights on again and I take it back in a week not sure what they will do next

So your coolant is disappearing? How often does this happen?

Within two years, I was adding liquid to the tank because it was slightly reduced and the message about the lack of liquid was displayed.
I do not have any leaks.
My brother-in-law had 4 Qx30 cars and that problem too.
I am not sure if the coolant is evaporating and therefore it is decreasing.

I looked at the cooling system in my qx30.
I noticed that the conduit from the tank to the radiator is slightly damp and has a white coating. In the place of the stub pipe at the cooler, but not on the coupling, but in the place where it is thermally clamped. It seems to me that under the influence of temperature it loosens and then the liquid leaks and therefore there is less of it with time.

Someday I will buy a new cable and replace it. I'll see if it helps.
