The LS500 exhaust system has two GPF (gasoline particulate filters). These cars seem to have a propensity for emitting white exhaust smoke in cold weather. Could this be due to the gasoline particulate filters that Lexus uses on the 3.4 twin turbo V6?

Sorry, I’m referring to the old conventional one-piece spin-on type that most cars have used for decades like my 2002 LS430 uses.

This vehicle does use a cartridge-style filter, as seen in the link, above.

Any thoughts on why 23LJ01 (2nd Key Fob program) is not listed as a service campaign on the status/health tabs of the Lexus app? I have reported to the NHTSA as I see this as a safety/security issue. The digital key is very glitchy and could leave one stranded. Lost phone or dead phone battery or dead spot could also leave one locked out and stranded. Lexus should have, at the least, provided a lower tech card key as a backup.

Why did they have to reinvent the oil filter instead of using a regular spin-on type like most other vehicles for the past 50 years?

What are so mods I can do for a Lexus RC 350

O2 sensors changed. still no help with rough idle. car starts fine. Lexus claims it's due to faulty fuel injector system flooding the right cylinder bank. they claim fuel injection system is unavailable. any ideas? spent about $4500 to fix and still have the problem could you a little advice. thx / Rog

Thanks! I have done reprogrammed the windows for sure. I'm going to start looking at a junkyard, but it'd be awesome to find an aftermarket.

A bit of an update. Have had the LS460 on a battery tender all winter. Car hasn't been driven for about 35 days, prior to unplugging the tender. Took it off two weeks ago as I was going away and didn't want to plugged in while I was gone. Got back, measured the battery voltage, still at 12.67 after 14 days just sitting. So the good news is, for longer term sits the car must go into a deeper sleep than what I was first measuring. Once it has sat un-driven for a month or so, the draw must drop to nearly nothing as 12.67 is virtually a fully charged battery. If the draw had remained at even 40 Milliamps, it would have drawn it down more than that. So a battery in good condition, and a car stored in heated indoor storage, no alarm armed, appears to be able to sit for very l;ong periods of time without flattening the battery.

Good point. I often can find an electronic version of the service manual, but there are cases when only article/video comments are found. I guess we can say that those should be taken "with a grain of salt". Thanks for your comments.
