I have a 2017 red sport q50 with 65k miles that I purchased back in November 21. I believe I still have some factory warranty left and I have the extended max care by Infiniti. I got one of the turbos replaced at about 55k miles. A couple days ago when I put the car under moderate acceleration I would hear a quick chirp, but it wouldn’t happen every time. I was checking my oil level yesterday and realized the coolant reservoir for my turbos was below the minimum level and i couldn’t even tell that there was any coolant in there. I got more coolant added in to fill it to the max fill line, and I haven’t heard the chirp since. I’m not sure how coolant could have just escaped from the reservoir and I haven’t noticed any signs of leaking under the car. Where could it have gone… is this something I should be worried about and have it checked considering I had issues with the turbos before? They only replaced 1 turbo, and I’ve heard that with some cars when 1 goes bad the other one will usually be affected as well. Does anyone have any insight on this?
