I would check it first, to see if the sensor is faulty, before buying anything.
This happened with our car. In the winter the car would say the coolant was low, but it really wasn't. They replaced the whole entire Coolant Reservoir and Flushed/Changed the coolant. It was free of charge for us at just under 18k miles.

I couldn't find a thread on this, but I got a notification on my screen that I need to add some coolant to my car. It says to use Infiniti coolant or BASF Glysantin G40. I don't feel like driving over to my dealership for such a small thing. But, it doesn't seem like BASF Glysantin G40 is sold in regular auto shop stores. Or is it? Any ideas?

Thanks!
Just started getting the same thing

If your coolant level is fine, then you might have a faulty sensor in the coolant reservoir tank.

My wife's had the coolant level warning pop on last winter, it wasn't an error, but it was also barely low (reading just below the plastic +). Added about 4oz of distilled water and has been fine since.

@tomrs I just dropped mine in this morning for what looks like the same issue, coolant leaking around the turbo area. I had the coolant low light pop up and topped up the fluid about 2 months ago, checked it again and it was about an inch lower so did some poking around and found some drops. Problem is the dealer said "This could take a few days as we need to ship in the specialised part, the whole coolant line from the turbo needs replacing" so i've got a weeks wait. Here is a pic I took looking up towards the rear of the turbo, you can see the dried and fresh coolant around and where it looks like it is coming from. View attachment 2362
My wife's is leaking from the same area. She's at 99k miles on her 2018, and I've been following the leak for about 2 weeks. It went to the dealer once and they couldn't find anything, but I was adamant it was leaking ever so slightly. It's coming from I believe the outlet coolant hose on the turbocharger.

Also, hers occasionally gets the "check coolant" message on the dash for low coolant in the reservoir. Only when it's cold outside, and it has never been low.

Looking at the white lines on that hose, it would seem your leak is higher up than your picture indicates.

Yeah, that was me laying on the ground looking up between the splash shield. It's coming from behind the clamp on the one hose coming out of the turbo and dripping down. Keep in mind it was probably doing it sporadically for several months before I noticed and gradually creating those dried up lines. It's amplified now that it stays sub-35F 24 hours.

Looks like it is ZEREX G40, per Google.
The coolant color in my QX30 is pink. Would this coolant work although the website indicates it does not fit QX30?

What about this coolant?

Thanks in advance.

The manual says to use "Genuine INFINITI Engine Coolant or equivalent in its quality BASF Glysantin® G40®". Because the QX30 uses a Mercedes-Benz (German) drivetrain rather than a Japanese drivetrain, you should not use anything other than the pink coolant since it is formulated for our cars. I believe that the Zerex G-40 should be perfectly fine, especially since it matches the exact formula required for our cars according to the manual. If you need to, get in contact with your Infiniti dealer and see what they say.

Zerex G-40 is okay to use. O'Reilly Auto Parts typically stocks it, in store, in my experience.

The Aisin part lanomo listed is NOT compatible. Don't use that.

Same issue in Pennsylvania - seems like a recall should occur if INFINITY is paying attention. Thanks
There is a TSB on this issue. Go to your dealer and they should immediately know to replace the reservoir. You shouldn't even get any hassle about it.

It's not safety related, so unlikely to ever see a recall.
