Brief history - leased my '17 Q60 Red Sport AWD w/3.0L V6 TT (VR30DDTT) in November 2016. When the 39-month lease term ended in February 2020, I bought the Q60 from Infiniti Financial for a favorable residual-based price. Throughout my 6 years of driving it, my only warranty items had been both inner driver's and passenger door seals were leaving smudges on the glass, so the seals were replaced to address the issue.
With 33,500 miles on it, last month I noticed a slight whistle occurring under moderate to heavy boost. Since the Powertrain Warranty was expiring on Nov 16th, I made an appointment on Nov 10th with my local Infiniti dealer to identify the whistling under boost. The next morning, I was given the prognosis - the whistle is from one of the turbo impellers that is rubbing on the center housing of the Central Housing/Rotating Assembly (CHRA), and the dealer is recommending replacement of both turbos AND the engine. Why? Well, the metal bits from the housing are likely getting into the combustion chamber(s), so to eliminate a future engine issue, the engine is replaced, too.
After 2 1/2 weeks at the dealership, I picked up my Q today. I simply signed the dealership copy of the WO and drove off. $0 out-of-pocket. When I got home, I looked over the WO, and the revised retail estimate (if out-of-warranty) would have been $37,122.60! Yikes!
Going forward, the new engine and revised turbos have a 1-yr/12k mile warranty.
Note: It's a real shame this engine had to be replaced due to a turbo bearing failure - the engine still ran good, quiet at idle (for a DI engine!), and it had excellent Blackstone UOA results since new. The 5k OCIs with Valvoline Modern Engine just couldn't overcome a poorly-designed Garrett CHRA, apparently.
