r/LexusGS350

Soooo, just took home a 2015 GS 350 F Sport with 96k miles from CarMax.

Issue: While using the normal driving mode (not the manual mode) normal and eco mode both give me a clunking sound in the rear when I give it a little bit of throttle. When it's full throttle, don't get the clunking sound. Minimal to medium throttle = Clunking sound.

When I'm in the "manual mode" I do not get it at all.

Thank God for the 10 day warranty.

I don't know if I should keep it and have them fix it or give it back to them. Besides that, there are a few rattles here and there (driver's side interior door handle when going over bumps, CD player is basically continuous)

Should I even waste money on a Post Purchase Inspection?

It's a bit of a bummer but at least I can bring it back.

Hey everyone,

I’m considering purchasing a 2013–2017 Lexus GS350 or IS350, likely somewhere in the 80,000–180,000 mile range, and I wanted to hear from people who have owned or driven these cars long-term.

I know these cars are generally known for reliability, but with higher mileage examples, I’m trying to figure out what maintenance items or common issues I should specifically watch for before buying.

Some things I’m curious about:

• Common mechanical problems on the GS350 or IS350
• Expensive repairs that tend to happen around higher mileage
• Transmission or AWD issues to watch for
• Carbon buildup concerns on the direct injection engines
• Suspension wear or steering issues
• Water pump, timing cover leaks, or oil leaks
• Maintenance records that are MUST-HAVEs
• Whether 150k+ miles is still considered safe on these cars
• Differences in reliability between the GS350 vs IS350
• Any red flags during a test drive or pre-purchase inspection

If you own one or previously owned one, how has reliability been for you?
Would you trust one with over 100k–150k miles as a daily driver?

Also, are there certain years/trims/options I should avoid or specifically look for?

Want to join the Lexus fam for my first car and keep this car long-term.

*Bonus points if you’ve owned both the GS350 and IS350 and can compare them.*

I used to own a Toyota Crown Athlete G 3.5 (GRS214) in Japan. Before moving to the USA, I bought a brand new KYB Extage complete suspension kit (EKIT-GRS214 (springs + shocks/struts)) but I sold the car before I ever installed it.

Now that I’m in the US, I’ve heard that this kit might fit some Lexus GS models here, but I can’t find any definitive information online.

My Crown had the factory electronically adjustable sport suspension (Toyota AVS). From what I understand, the GRS214 shares a lot with the Lexus GS platform, but I’m not sure which exact USDM GS would be the closest equivalent.

Does anyone know:

Which Lexus GS chassis/model is mechanically same with the GRS214 Athlete G 3.5, and whether the KYB EKIT-GRS214 suspension can bolt onto a US Lexus GS?

If so, would it only fit AVS-equipped Lexus GS models?

2015 GS 350 F Sport

Price: $21,998

Mileage: 96k

Owners: 2

This is the only GS 350 remotely close to me, besides one that is a 2013 base model with 120k miles for 17k.

Can I change the staggered setup on the F-Sport to square?

Edit: I need a vehicle soon because of transmission issues with my current car. Can't really afford to wait. There's a 2016 Acura TLX Sh-AWD V6 for 20k, but I really prefer the GS.

Anyone else find the lumbar support too low down ? I find seats uncomfortable . I have the car a year and I'm selling due to this and i just find the car boring to drive it's 2013 gs450h .

I’ve been having issues with very slow continuous drain on my battery for a few months now, had the original dead battery replaced, the alternator replaced, and still my new battery was fully dead after 5 days of not driving (I was out of town).

Parasitic draw has been ruled out, every fuse was checked. As of yesterday the battery was holding stable at 12.2, but my mechanic can get a new agm battery to swap mine for so might take him up on that.

Does anyone have any recommendations for agm batteries? I’ve heard it needs to be reverse polarity, but thats a little above my head to be honest so I’m not entirely sure what that means I should look for.
