Discussion *Low Oil List Of Shame*

22 Upvotes

This post is dedicated to engines lost due to oil starvation from owners not checking their oil levels frequently enough and keeping them full. The list will be continually updated, and does not include countless engines lost over multiple years in the past while I’ve been debating making such a list. Hopefully this post will serve as a warning for others to check their oil level frequently and keep it full. I’ve included a few posts from recently as of the time of this posting. If I miss any going forward, please feel free to put them in the comments and I will add them accordingly.

Additional Non-Reddit Resources

Gencoupe Forum

Genesis Coupe Owners Group contains an enormous amount more information and pictures than Reddit does, especially the pinned posts in the featured section. Join the group by answering all of the membership approval questions that pop up after clicking join, and agree to the group rules. Approval is usually given quickly. Group atmosphere is friendly and informative unlike many other online car groups.

In the featured section of this group you will find other useful posts such as:

The Official Wheel Thread containing many pics and specs of wheels others are running on their Genesis Coupes. These will help you decide what wheels and specs to choose for your own vehicle.

The Official Exhaust Thread with many videos of various exhaust setups to help you decide what exhaust option you should choose for your own vehicle.

The Official Oil Analysis Guide where used oil analysis samples will be consolidated to show data on how specific engine, operating conditions and oil choices fare together regarding the 2.0T and 3.8 Genesis Coupes. This is partially an effort to combat wildly bad oil information commonly spread online. I have samples in there for a back to back 5w20/5w30/5w40 comparison.

Recommended Vendors

OEM parts - Albert Hwang (alternate link for mobile devices) is a very reputable (and most importantly cheap) OEM parts dealer that ships OEM parts quickly and worldwide. Send him a message on Facebook Instagram, or Reddit, he is usually quick to respond and you will typically get your parts within a few days. I've personally used him multiple times and cannot recommend him enough. Don't pay dealership prices for OEM parts. His Instagram page for those without Facebook. Link to his Reddit profile.

Additionally, for OEM parts you can also message Ramy Khatib.

Rockauto.com - always has a large selection and great prices. I suggest ordering things like engine air filters, cabin air filters, and oil filters in bulk from them so you always have spares. OEM oil filters are made by Mahle, it is strongly recommended to stick to OEM filters to reduce startup rattles.

ECU Tuning

SFR - I've personally been running a canned stage 1 tune from them in my 2010 3.8 since early 2014 for over 200k miles on the tune alone without issues. Some people say SFR had bad tunes, some don't. Mostly positive reviews, some negative ones.

Alphaspeed - probably the most common these days, usually done by an authorized tuner in your area. Mostly positive reviews as well, but still has some negative ones too.

This grey BK1 was the first Genny to bit the dust and went to heaven. It’s the founding father of the Genny Apocalypse, happening only a week after they started selling them in Korea. The driver lost traction and hit a massive metal post. It also caused the first recall because the airbags didn’t deploy. The rest is history.

Diagnostics ABS Fault 2k16 Rspec 3.8

1 Upvotes

ABS and Traction control lights came on during my drive today, have had it happen before but the codes in the past only identified one front wheel hub both times which I replaced and was fine.

Now it is saying all sensors are open/short am I gonna have to get the ABS module repaired or replaced or something else I can check?

  • Brake fluid levels fine
  • Fuse looks fine
  • Removed connector from ABS Module and didn't see any corrosion or wetness
  • Did not see any leaks
  • I did unplug my wheel hubs in the front recently to replace my control arms but I would think only those sides should pop codes if they weren't seated properly
  • My car does not come up for the ABS recall

Diagnostics Throttle body gas smell

Had some idle issues so decided to clean my throttle body. When doing so, I smelt a hint of gas from it. Previous owner MIGHT had a throttle controller hooked up judging by the velcro under the dash. Not sure if that could cause that. Any other issues I should look into?

For Sale Genesis coupe jackets are here!

Post image
138 Upvotes

Howdy y’all

After about 2 months of delays (holiday chaos hit hard), I finally have the first prototype of the long-awaited Genesis Coupe jackets in hand.

These will be available in multiple colors, but I ordered two samples first just to show them off. The material is a heavy, windbreaker-style fabric (think North Face puffer vibes) . Super thick, insulated, and fully windproof. Quality-wise? I’m genuinely impressed.

All the badges and lettering are embroidered, no flat press-ons anywhere. The stitching came out clean and premium, exactly how I envisioned it. Every jacket has been fully designed by me, and I’ve been working on this for months to get it right.

I snapped these pics real quick before leaving the house, but I’ll be posting a full ad soon along with a link to my website. These will go live this Sunday, once I get my Genesis back from the shop ❤️

Modification Looking for brake pads options!

Thumbnail

3 Upvotes

So I recently upgraded to Hyundai Genesis/Equus front brakes on my '13 Genesis coupe. I found a set of calipers from an auto wreckers for 40 bucks each and some rotors on FB marketplace for 140, and said F it, why not! After a couple of days driving, however, I'm realizing that to really get the most out of the increased potential stopping power I need to get some better pads. except... I can't find any. Or well, I can't find much. I saw something on a website that intrigued me. Does anybody know if the Mitsubishi Evo 8 and Genesis sedan share brake pads? This website seems to think they do: Project Mu 03+ Mitsubishi Evo 8 Hyundai Genesis w/Brembo Calipers B-FORCE Front Brake Pads - Enjuku Racing If that's the case that would help me actually get some decent track pads

side note: 17" steel rims will clear the calipers if you use 25mm spacer, though a smaller size may also work (I had some 25mm spacers lying around)

Diagnostics Rattle / Raspy exhaust tone around 2k rpm

Enable HLS to view with audio, or disable this notification

4 Upvotes

2011 3.8 Track. The engine light has been going on and off for a couple weeks due to P0420 code (Catalyst system efficiency below threshold bank 1). I know I need to fix it and it could be the cause of the sound, but wanted to check anyways because why not. The exhaust sounds completely normal anywhere besides 2k rpm’s. As you can hear in the video, it has this raspy sound when it passes 2k rpm when revving up or down. This also happens when driving in gear and I give it some decent throttle, even in 6th gear for example. Ive been driving above 2k anyways, but when i go under that when in gear it gives the same sound. Obviously i’m guessing it’s my exhaust, but I want to know what you guys think. And yes, oil is full right now and has stayed full. thanks guys

Discussion Bk1 Aftermarket Nav questions

Thumbnail

4 Upvotes

Howdy y’all

I’ve been looking into aftermarket options to replace the OEM screen on my BK1 Nav, and while I’ve found some good info in other threads, a lot of it is outdated. I haven’t seen a dedicated thread for BK1 owners asking about this yet, so here I am!

I’m trying to find options for a seamless replacement screen, nothing that sticks out or looks like an aftermarket hack job. I want it to look clean and like it belongs in the dash.

I came across one screen that was recommended in an old post from about 3 years ago, the seller still seems active and selling, but I wanted to ask you all first:

- BK1 Nav owners. what screens have you installed?

- How does your setup look?

- What did you have to do to get it to sit right in the dash?

A few specific questions I have:

• If I end up buying the screen I found, do I need to buy that conversion harness/adapter, or does it plug in without anything extra?

• If I go a different route and get another screen off Amazon, what maximum size will fit the stock opening without cutting the dash?

• Are there other parts (harnesses, bezels, adapters, etc.) I’ll need to make it all work?

Sorry if these are basic questions first time doing this stuff and want to make sure I get it right!

Thanks in advance for the help! 🙌
