Thanks for those links, Anita. I spent the entire weekend working on various final details for selling our Excursion (upper and lower radiator hoses, serpentine belt, thermostat and stat housing, coolant flush, oil change, oil cooler removal & cleaning and new cooler o-rings, and washing/detailing engine bay). I feel like I've been beaten from head to toe -- getting more mature can sometimes be a real pain (in every joint).
Anyway, since I do not have the oil cooler, I'll be holding off on any of this tow-package-related work until after our annual Fall Long Weekend Getaway (this weekend).
2011 RX350 71k miles. Went to the dealer last week to replace rear shock absorbers under extended warranty. SA called on phone after a couple of hours to tell me they did the multi-point inspection and found the oil cooler line has a small leak and will be replacing them. I looked at it after parking in the garage and saw 2 shiny oil lines. Description on the paperwork handed to me is "Check for oil leak and advise. Cause: Service campaign. AHG56D ZLC-Inspect oil cooler pipe. Part #04004-29131 Pipe, Oil Cooler".
WOW, I guess Australia got the extended warranty version! First I have heard of this oil cooler line problem so no recall issued or we would have had it done by now.
We have had our RX350 since new, build 2009, on October 13, 2017 had serviced at 200,440 kilometers (124,548 miles)
On November 30, 2017, my wife was nearly home when the Oil Light came on. I looked under the bonnet (hood) but could not see anything.
But looking under the vehicle, it was covered in oil. This was 206,854 kilometers (128,533 miles) Arranged a tow truck the next morning.
When picked up the vehicle, all the paperwork says is: Replaced oil cooler pipe under warranty
From my research on the internet, seems that this is a well known potential problem but Lexus only address it with a fix it if & when it breaks? Why wouldn't they include it in future MAJOR service for long time owners, say 100K or 200K (or similar for miles)???? I mean there is such a for a total engine failure, say if the Engine Light Warning was not functioning or burnt out; or someone on the freeway and doesn't notice it? Another thought, in industrial situations like large CAT generator engines, loss of oil pressure will shutdown the engine but cars don't do this? Amazing !!!

I can't speak specifically to the RX, but I know my 84 Buick Century had an oil pressure sensor in the crankcase. When my oil pump failed the car would not start due to no oil pressure. I would be surprised if the RX did not have that feature.
Hello all - yesterday came across this thread (https://www.clublexus.com/forums/rx-...-pictures.html) on the RX 2nd Gen forums and was quite surprised. There are a couple of guys on that thread who say that one of the issues (Oil cooler line VS VVTi line failures) was there in all vehicles equipped with the 350 engine manufactured till some time in 2008. The other issue (getting confused which is which) is said to have continued on these engines till sometime in 2012.
Now, my wife drives a 2010 RX350 AWD (with Nav) that we bought Jul 2015. Looking at the service history on the Lexus Owners website shows pedal replacement as the only TSB kind of work.
Can someone please confirm if either of these issues is a possibility on our 2010 RX350? If yes, we would be willing to spend the money to get it fixed - either at Lexus or at our preferred independent repair shop. If someone can help look up with VIN#, I can PM that as well.
Also - I am searching for a replacement for my 2005 Pilot that has 305k miles and a 2007-2009 RX400h was one of the vehicles (amongst several others) on my mind. Can someone say if either (or both) of these are potential issues? - I suppose asking this question on the 2nd Gen 400h forum makes more sense - will do that if I don't get any confirmed answers here.
That is correct for the VVT-I line. The tow package oil cooler line is a different issue. I think all RX vehicles with the tow package had the rubber line up until 2012 or 2013. IF you 2010 has the tow package, follow the photos in the thread above to check if you 1) have the tow package and if so, 2) have the cooler line. Your 2010 does not have the VVT-1 issue.
Ssd108 - the RX400h is the 2nd gen vehicle and is covered in a different forum.
Thanks, so 2010 comes with all metal VVT-I line?
because lexus was replacing recall hose with rubber hose, but they were telling that's better rubber? which I did not trusted.
I also replace oil cooler with all metal.
All 2010 (maybe even 2009 which was the old body with the new engine) were manufactured with the metal VVT-1 line. For more information on the oil cooler check out http://www.toyotanation.com/forum/12...solutions.html as the Highlander is a mechanical twin to the RX350
I just did this install and thought i’d Make a few comments about it. I watched the YouTube vid from post #34 above, as well as the second gen highlander forum thread about this. I had to take 3 out of the 4 bolts (studs) out to get the new line in. The only bolt/stud I left alone was the one on the oil cooler side bottom, closest to driver side. It’s the most difficult to reach. The tightening torque for the nuts and bolts are 15 ft lbs according to 2 separate sources, but it seemed like the studs just kept going, so I stopped at about 11 ft lbs. , the nuts then went on and torqued to 15 ft lbs. After tightening the nuts, the threads of the 3 studs that I had to remove had 3 thread grooves showing, while the untouched stud had 4 thread grooves visible. At least the torque wrench was consistent, but I was concerned of not having the same amount of thread showing as the untouched stud. Running the engine had no leaks, so I think it’s good. If any others encountered a similar issue regarding the bolts I’d like to know, or if those in the know about nuts and bolts can comment whether it’s OK to have one less thread showing compared to original, it would be nice to hear from you.
Happy year ear of the dog!

Reason: clarifiy bolt stud
I pulled my front splash guard last night, and it appears I do NOT have the oil cooler. I DO have other evidences of a Tow Package like the transmission cooler, hitch, and 4-prong wire connector. Look at the pics below and tell me if I'm wrong.
This is the same situation that I am in. I looked yesterday for this oil cooler line, couldn't find it. I have a 2010 RX450h FWD, I was surprised I didn't have it.
