Why would Toyota not learn from the previous 2GR-FE engine's known timing cover leaks, do to using a fault prone silicon bead installation method, rather than a tried and true manufactured gasket for the newer 2GR-FKS engine. This must be a make work project, to require several days of labor to completely remove the complete engine drivetrain to repair this leak of per this
update. Dealer replaced rear main in about 4 days. Picked up the vehicle and immediately noticed wheel misaligned and scratched wiper arm. Took the vehicle back to the dealer and fixed the issues in 4 days. Only time will tell if the repair holds up or any other issues arise.
The 2022 RX loaner I had with ~6K miles was also developing a leak in the same area.
Generally speaking, main crank bearing failures are pretty rare, assuming regular oil changes and no leaking to low oil level. One wonders whether Toyota got a batch of defective bearings or good bearings with bad seals, or something like that.
I have a 2019 rx350 with 52K miles with oil changes at the dealer every 6-8K miles. Yesterday, I noticed an oil leak between the engine and the transmission housing. It appears to be a rear main seal leak.
I know this repair will be covered under the powertrain warranty. However, what are the chances of having new problems arise after the dealership disassembles to front end to fix the leak?
wondering if anyone here had their RX with premature failure of a rear main seal repaired by dealer.
So I discovered my RX350 has the same dreaded timing chain cover oil leak as so many others on this thread have discovered. Regrettably I am just out of warranty, 84K miles and tranny had 72K miles warranty. Dealership quoted $6k tab for the repair. Has anyone here been able to get Lexus sop to help out in any way. This is my first Lexus and I bought his due to the high reliability and low cost of ownership reputation, so much for "Lexus just needs oil changes". This is clearly a known issue that's happened to a lot of owners.
What's the level of urgency with getting this repaired, can I top off whatever oil goes into the cover so it doesn't run too dry.
The timing chain gets a steady supply of lubrication from engine oil so it shouldn't run dry. Check the oil dip stick and see if it is low. It's not urgent unless it is dripping on the pavement. Drops of oil can work their way onto the serpentine belt and cause the belt to slip and deteriorate quickly.
I just went and got my oil changed at the dealer and they saw oil seepage at the timing cover. Originally they were going to get me a loaner and get the work done to fix it as my vehicle is still under warranty under the 4 year/50,000 miles, but then they came back out after about 15 mins and said that since it's not fully leaking oil on the ground or anything and that it's just a small seepage of oil at the timing cover, they won't need to fix it yet and told me to monitor it for now. It's not leaking on the ground or anything. The thing is, my vehicle is almost out of warranty now, is this something I should push them to fix while I'm still under warranty even though it's a small seepage right now and not a major oil drip at the timing cover?
Thank you,

Reason: More information
The TSB is clear no warranty fix unless there is a drip or more of oil. Silly but that's what you are dealing with.
So this wouldn't be covered under the warranty? Is this a huge issue because I saw other posts indicating like this may be a common issue with the RX 350?

No it won't, the TSB (can't find it off hand) says there has to be drip(s). Very poor form on the part of Lexus IMO. The problem typically slowly gets worse.
could you try another dealer? One of them may be willing to fix it under warranty.
Yes, I was thinking that as well. I was going to try asking them again tomorrow but if they say no, I may try calling another dealer. The only part that worries me though is that if they are able to cover it under warranty, this repair would involve pulling out the engine as well.

I wouldn't call. I'd bring the car in again and ask to speak with the Service Manager. I'd get it fixed now, if the dealer with do it.
