2018 Nissan Armada that I bought used in spring of 2019. Direct injection engines are always chatty, but this one developed a knock in the lower portion of the engine over time. At around 80,000 miles in 2022 the engine developed significant valve tapping in the top end upon startup. There is a TSB that covers the issue and I had my engine scoped by my mechanic per the TSB. The scope revealed oil starvation damage to the engine as described in the TSB. It required repair is a short block replacement to the tune of $11,000 at the dealership since my vehicle is out of warranty. Nissan knows it has an issue with this engine (issue originally cropped up in Titan pickups and it is now showing up in Armadas and Infinity QX80s) but they have not issued a recall or extended warranty coverage. I've moved on to a Lexus and will never consider a Nissan product again.
