I performed a basic oil and filter change on my 2024 NX 350h today after 1400 miles. Easy process. A priority for me was installing a magnetic tipped drain plug. Sure enough, in the old oil was a surprising number (maybe 10 or so) of metal flakes, the largest being about 2mm. I will change the oil again in about another 2K miles. I suspect I'll find more flakes, but this time they'll be attached to the drain plug!

PS: I'm loving this car more and more each day

I performed another oil change on my NX 350h at 3,250 miles. Previously installed magnetic drain plug showed only slight traces of metal and I saw no "junk" chunks as I did with the initial oil change. I see now that Tundra pickups are being recalled for problems attributed to "machining debris" left in new engines. Problem supposedly applies to Lexus LX as well.

Yea, they are looking at potentially replacing up to 100,000 engines due to metal contamination. Probably will turn into an extended warranty TSB but we'll see how many actually end up failing in the longer term because of improper clean prep. I'm sure someone at Toyota now has a butt that looks surprisingly like a work boot. All the more reason to do a break in oil change. I had already changed my oil twice by the same time as you did, good thinking!

Update: Mileage on my NX 350h is now at almost 5K and have decided to change oil again at this point prior to the upcoming dealer 5K service. The magnetic tipped drain plug is doing its job and was slightly coated with some "black dust" of very fine ferrous metal. Later I checked the bottom of the oil drain pan and found just 3 or 4 tiny beads of other metal, so I'm confident that the manufacturing process "debris" is pretty much gone. Now I hope to settle into 3K intervals for oil changes hereafter.

You dropped the oil pan?
