2016 Red sport
79k miles (Bought car used with 27k in 2019)
Had to refill engine coolant every other day.
I want to say the problem may have been getting worse as time went by since I did notice small amount of coolant missing every month in 2021(didnt go below min. mark, but I know coolant level shouldnt be going down at all unless there's an issue), no leaks, pressure tests conducted 2 times that year, all passed, no white smoke, oil analysis done in July of 2021, negative for coolant in oil.
May('22), loosing coolant every other day. did an oil change, noticed oil was creamy, white cream built on the filler cap, sent sample of oil for analysis. Car didn't overheat, but fans kicked on more frequently, brought into dealership beginning of June for diagnosing.
Sadly, I had over 75k miles at this time, but had warranty with a company, which did make things difficult. After 2 inspectors and inspections by different Infiniti techs, it was determined that I had a porous block & bad turbos...engine internals and block had no cracks/signs of extreme wear, no metal shavings, etc. Oil analysis came back positive of coolant mixed in.
Total bill came to 32k (long block, turbos, labor). Had to pay 5k, warranty company wanted to replace using a used motor, but after arguing(infiniti service writer helped) new motor was determined. Dealer did hook me with all new engine components (wasnt included in original RO), didn't charge me the loaner I had for over a month, gave me extended warranty and other small goodies that made paying 5k worth it since the repairs did cost more than what the car was currently worth. I just got the car back on July 25th, brought it in June 7th. Once things were approved, took 1 week.
Mods - JB4 (disabled unless I was going to "race" someone, or when i wanted to have a little fun). LDPs, Y-pipe, AMS intakes.
