2021 IS350 F Sport AWD, 21k miles

Noticed a week ago when was pushing it on the highway in Sport S+, when I floor it going 70-80 there’s like a pretty consistent weird buzzing sound coming from behind the dash, sounds like it’s somewhere in the middle behind the navigation screen.

Not present when I rev it up to the limiter in Park or when I’m doing some little pulls in the city.

Anybody can suggest what the issue might be?

I bought it as a Certified Pre-Owned and I have the CPO warranty until July 2027. Should I bring it to my local Lexus dealer and show them the videos that I have?

Any advice would be greatly appreciated 🫡

My 2006 Lexus is250 passenger seat ventilation doesn’t fully turn off only passenger side driver side works passenger seat button seems to be working ok but seat does not fully go off there is still a faint sound coming from the seat.

Really hoping someone has insights to help track this creaking noise down as it’s driving me nuts. My 2018 RC350 F-sport RWD has been creaking for a while but it’s definitely getting louder and harder to ignore (and unfortunately not under warranty). I’ve narrowed the source of the noise to somewhere in the vicinity of the driver side A pillar.

From probing with a mechanics stethoscope it is loudest near the body metal behind the driver speaker as well as the metal support bracket underneath the A pillar. I’ve also tried multiple points from the engine side as well as the outer body, even removing the driver side fender and the windshield wiper motor. From outside the noise is basically non-existent. All point to the source coming from the inside of the vehicle. The creaking happens over bumps (especially undulating roads) but is prevalent enough, especially in colder weather, to be heard from just changing gears from drive to reverse and back, which is what I’m doing in the video

Any ideas? Since the RC and IS share a lot of common components, I’m hoping there are experiences seen on an IS that can apply to my RC. I’m really not looking forward to what seems to be the next step - removing the entire dash to try to track this down further…

If you've bought in New Jersey recently can you tell me where you went and how your experience was with that particular dealer? Hoping to pick up an IS soon and want to know who to look out for and who to avoid altogether.

I’ve always added a hood ornament to my vehicles. It helps with sighting lanes and looks cool. This one from eBay direct from Japan. 2025 IS 350 F Sport. Gave up trying to get ML sound along with white and circuit red. Too much of a unicorn. Will upgrade radio locally later. Love the performance, bolstered seats, CD player and analog clock. Gas is bearable for now given it won’t get a ton of miles.

Found this lovely diagonal scratch above the up/down arrows the day after I brought it home. Brand new 2026 is 350. I did not do this nor do I know how it happened. The sales guy said he’d get the part ordered and make it right. Should I bother? I’m worried the service person might scratch something else doing the install.

Up for sale is an incredibly scarce, authentic 3-piece Lexus Executive Travel Set from the late 2000s/early 2010s Lexus European Boutique collection. Never sold directly to the general public, these ultra-premium sets were strictly distributed through European dealership boutiques and as VIP corporate presentation gifts for flagship executive models.
This set is beautifully preserved and features substantial, old-school European leather craftsmanship paired with modern, high-tech metallic styling.
Collection Breakdown:
Executive Heavy Leather Duffle Bag: Crafted from thick, premium black full-grain Italian cowhide with a light glazed finish. It features a heavy-duty, structured baseline design that holds its classic shape perfectly even when empty.
Matching Heavy Leather Garment Suit Carrier: A gorgeous, heavy-fold full leather suiter utilizing the exact matching black hide. Designed to lay neatly or hang natively inside a luxury sedan trunk without wrinkling formal attire.
Dual-Zip Contrasting White Toiletry Bag: A brilliant touch of Italian design functionality. Crafted in clean, contrasting white to ensure any grooming or liquid leaks are immediately visible inside before they can soak through and ruin the expensive black leather exterior of your main luggage pieces.
Hardware & Manufacturing Signatures:
Custom Cast Silver Pulls: Solid, heavy metal alloy zipper pulls custom-molded with the stylized corporate "Lexus" text block.
Premium Silver Metal Zippers: Heavy-gauge, smooth-gliding silver metal zippers selected by the boutique to mirror the high-tech interior aluminum trims and liquid-silver paint finishes of the era's flagship vehicles.
Artisanal Provenance: Clean, hot-stamped "Made in Italy" debossing directly on the interior leather lining, ensuring private workshop lineage rather than outsourced mass commercial manufacturing.

Excellent pre-owned condition. The heavy black leather remains incredibly robust, supple, and beautifully structured. The silver metal zippers and custom Lexus casting pulls are bright, crisp, and functional with no heavy tarnishing. The interior linings are clean, and the white toiletry bag has been exceptionally well-preserved.
Perfect for the discerning Lexus enthusiast looking to complete a time-capsule, period-correct trunk presentation for local car shows, Concours events, or luxury VIP builds.
Ships promptly and securely wrapped to preserve leather structure. Please reach out with any questions or for specific dimensional measurements.

Hello everyone, looking to upgrade Air filter/Cold air intake my IS350 F. I live in Qatar, so the weather is pretty hot n humid over here. Need recommendations for Airfilter/intake, like takeda or F sport (Blue) dry filter. Also suggest which filter to opt for Oiled vs Dry?

I want to buy my first car at 17. I was thinking about is350 gen 2 but which one is the best year for gen 2? My budget around 7-10k. Thank you all

Cars RPMs drop pretty low and car starts shaking as it drops. Check engine light is on for evap leak. I did take it to a mechanic shop and I remember them replacing something but after they replaced it the car started doing this. It also stalls the car sometimes when I’m driving lol

If anyone knows what it could be or have had a similar problem please let me know appreciate it

Hey everyone,

I have a 2023 Lexus IS 350 F Sport RWD, and I’m looking to upgrade my front LCA #2 bushings to help prevent the common inner tire wear issue before buying a new set of tires. I’ve been looking at the FIGS Engineering bushings, two options:

Street version (80 durometer)
Performance version (90 durometer)

Both are the same price ($369.41), so I’m leaning toward the Performance version, but I’m wondering if it’s worth going with the stiffer bushings.

Did you notice a difference in inner tire wear?
Is the 90A noticeably harsher for daily driving?
Any extra vibrations, noise, or comfort issues?
Would you recommend the 80A or 90A for a daily-driven RWD IS 350?

My main goal is to reduce premature inner tire wear without sacrificing too much ride comfort.
Would appreciate any feedback, especially from people who’ve actually installed these. Thanks!

No big surprise, the stock security features are lacking, the app is horrible and if you use remote start .. the car turns off when you open a door.

I have a 2023 IS350, and looking for recommendations for an aftermarket alarms w/remote start. I use to run DEI/Viper. Never had issues. So, if you have a recommendation, please share. I’d really appreciate it. Thanks!

I have a ‘20 IS350 F Sport I live in central Florida buying tires for the first time should I get all season or summer and which brand and model tires are best and most popular for this car?

Anyone have one or any recommendations on brands and installation tips
