2016 RX 350 build 8/16
Main seal was fixed with 55,000ish on it. Now at 133k it's leaking bad. Absolutely crazy. I have a 2008 four cylinder Camry and no issues. What the hell is wrong with Lexus?
Why can they not get a real fix for this?

What do you mean by main seal? Timing chain cover? Crankshaft seal? My RAV4 has the dreaded timing cover leak I'm not going to repair it I wash the engine bay once in a while it can leak until the car is put out to pasture.

My Honda Accord developed a rear main leak with 1000 miles on the ODO. I had a 93 Ford ranger with a 4L V6 that developed a rear main leak every other oil change (every 6K miles) while it was on warranty …then it went off warranty. I’m not excusing Toyota/Lexus - just sharing my experience with another brand. It shouldn’t be happening and oil leaks are enormously frustrating, but it could always be worse. I have owned a couple of Audis, and they were terrible leakers. I think every seal leaked on my last Audi.

Yep, common issue across all models with 3.5 - ES350, Camry, Tacomas, RX350, etc…
For most engines, it is more of a seepage than a leak. You may never notice low oil on the dip stick. It usually leaks where the timing cover, block, and head meet, the area above the PS pump. In our 07 ES350, and now our 18 RX350, the oil seeps down the block behind the pump and drips onto the CV shaft. I clean the area every time I do an oil change. On the ES I went to a thicker oil - 10w/30. This greatly reduced the seepage. On the RX, the seepage is less and I am still using 0w/20. The Car Care Nut guy did a video on this. To fix it, the engine needs to come out. Some folks clean the seepage area and apply silicone sealer externally. I may do this at next oil change.
