with that logic ours was one of the OG's! Last five of vin # 005389. Several cross country trips without any issues at all (knocking on wood) and I've now sent 3 oil samples from when I personally changed the oil to Blackstone Labs for testing (attached). We also let Lexus change the oil at their regularly scheduled intervals.Okay, yours is definitely a very early production unit, probably built around the 1st quarter of 2024.
Just for reference, based on what I’ve found online , a GX550 with the VIN sequence “20620” (indicating the 20,620th unit produced) had a recorded build date of August 2024. Refer to this link and scroll down where you can see the VIN tag on the car- Used 2024 Lexus GX 550 Overtrail+ For Sale (Sold) | Autobyzack Inc Stock #R5020620
So if yours is in the 2,000th unit range (02234), it very much suggests that your engine was built much earlier and likely still uses the older bearing design.
Ours did sit at the dock for 2 months when it arrived in the US for what they told us was the sunroof drain fix, who knows, maybe they did something else but the thing has been amazing and we're hoping to get our new 2026 OT any day now as we've been on the list in Houston since Nov 2025 (want the lift, onboard air, and memory seats). Will be getting every penny we paid back on trade-in (or $5k more on Carvana, but thats a wash with taxes).
Good luck to everyone but want to share after seeing that we may have one of the early ones and it's been issue free.
