2013 GENESIS SEDAN 3.8 V6 ( Newbie for help in new ownership )

[Liv2013]

Car Details:

• Model: 2013 Genesis Sedan 3.8 Premium Package
• Mileage: 208,800 KM (for our American friends, that's approximately 129,806 miles)

Maintenance & Concerns:

• I'll be reaching out to the dealership for a maintenance guide, but I'd love community insights first.
• My goal is to keep this car running smoothly for as long as possible.

Immediate Checks:

• What should be my priority inspections upon getting the car home?
• Current concerns based on feedback:
  • Oil combustion issues
  • Potential water leaks from the sunroof
  • Battery compartment in the trunk; some suggest sealing it. Should I do it preemptively even without noticing a leak?

Lighting Upgrades:

• Interested in transitioning to LED lights. Recommendations?
• For the fog lights, is there a requirement for them to be yellow?
• I've heard Hyundai doesn't list sizes. Confirmations or solutions?

Under the Hood:

• Should I consider a performance filter?
• Is there any benefit in proactively replacing parts like valve seals or piston seals, or is it best to wait until there's a noticeable issue?

Winter Preparedness:

• Any winter tire brand or model recommendations from fellow Genesis owners?

Thank you in advance for your advice and insights!

Immediate checks: Read your owner's manual. Battery vent tube must be installed.

Lighting: Keep it stock.

Under the hood: Keep it stock. Address any known issues. But don't tear into things to try and fix what ain't broke, because you'll break said things. Do your scheduled maintenance and any catch up on maintenance (plugs, belts, fluids, etc.) that you cannot confirm was already done in the available service history.

Thanks, I’ve been watching a bunch of videos about Walnut cleaning the engine piston valves. It looks like a very good solution to bring back the engine to its original state. (Some what ) Due to carbon capture around the pistons and such. Have you considered or seen others try the procedure ?

 

[Gunkk]

Considered? Oh yeah. Early 2010's GDI engines of all makes had issues with carbon fouling in the heads. That's why I've stayed with PFI. And yes, walnut blasting is likely beneficial at 200Mm. If you're going to have it done, ask the tech to take some before/after pics so you can share with the rest of the class

Walnuts...I haven't heard that in 40 years. Walnut shells were used to clean helicopter turbine engines 50+ years.

So it’s effectively efficient your saying.

So it’s effectively efficient your saying.

Walnut shells were used to clean the compressor and turbine blades blades of jet engines. I don't think I would use it on an automobile but I'm also not an auto mechanic. I have 41 years of aviation maintenance experience and during the brief time I worked on small airplane engines that used AVGAS(Leaded), that walnut cleaning was never mentioned.
Bottom line: Find someone you trust to check the vehicle out and check any service records from the previous owner(s). Check the CarFax ($25.00 I believe) to see any maintenance/repairs that might have been completed. They are great cars.
I have a 2014 with almost 209K miles that I purchased brand new.

Gunkk, I just went back and read your post, the tube ! its been on the ground in the trunk, not plugged in. the side it's supposed to be on is capped.. and the other side is open should I take off the plug, and stick the hose in, on the positive side.? but what about the other side. is it suppose to remain open or be closed?,

Mount the tube on the correct side. Swap the cap to the side not in use. Then it will vent correctly.
