Hello all. Been a while since I have been back here. Still loving my Stinger but have a recent issue at 74k miles. Had a nice "chat" with ChatGPT after talking to my service rep. They are still diagnosing the issue but figured I would document the issue here in case it helps anyone else in the future. I was able to upload the Kia Warranty and my Extended Warranty for additional context. I asked ChatGPT to summarize our conversation just so I had all the information organized.

Car:
2019 Kia Stinger GT (3.3TT)
~74,000 miles

---

Initial Symptoms:

• Check engine light with misfires on cylinders 1, 3, and 5 (same bank)
• Car would go into limp mode
• Issue would temporarily reset after restarting the engine

---

Escalation:

• Problem became more frequent
• Eventually the check engine light stayed on
• Car stalled at a stoplight (restarted after putting it in park)
• Dropped the car off at the dealer immediately

---

Dealer Actions So Far:

• Replaced spark plugs and ignition coils → did NOT fix issue
• Now diagnosing further with Kia tech support
• Mentioned finding oil pooling
• Indicated that engine replacement is a possibility (still under investigation)

---

What This Likely Points To (based on research + feedback):

• Not ignition-related (already ruled out)
• Likely a bank-specific issue (since 1,3,5 all affected)
• Most probable causes:
  
  • Fuel system issue (injectors / fuel delivery)
  • Turbo oil seal / oil ingestion
  • PCV system issue
  • VVT / cam timing issue
  • Internal engine issue (rings/valves)

---

Warranty Situation:

• Basic warranty expired (5yr / 60k)
• Powertrain warranty (10yr / 100k) still active
• Issue clearly falls under:
  
  • Engine internals
  • Fuel system
  • Turbo system

Dealer has not officially confirmed coverage yet, but this appears to be a legitimate powertrain claim

---

Important Notes for Others:

• If you get multiple misfires on one bank, don’t assume it’s just plugs/coils
• Limp mode + stalling = serious underlying issue
• Bring the car in ASAP and avoid driving it
• Let the dealer diagnose BEFORE paying for repairs yourself
• Even without perfect maintenance records, warranty claims can still be valid unless neglect directly caused the issue

---

Current Status:
Waiting on final diagnosis from dealer + Kia corporate
Will update once I know whether it’s a repair or full engine replacement

---

Hope this helps someone else—happy to answer questions or update once resolved. Some of this info is probably obvious to alot of you on here but I am not super educated on cars but love my Stinger!

Hi all,

Just into my second week of Stinger ownership and unfortunately I’m unconvinced this is going to be the car for me, but I’ve always tried to participate in owners clubs and communities so here I am. Also thanks to the community for all the content already on here, it was very useful when researching the car.

Bit of background: I’m U.K. based and have a red over black Stinger GTS (which I think is a GT2 RWD everywhere else in the world). I’m coming to this car from the love of my automotive life, a 2004 350z that I owned for 15 years, maintained mostly myself and did some significant but tasteful mods to. The stinger is supposed to be my grown up car now that I’ve got a new 120 mile round trip I’ll have to do once or twice a week.

I was sure before buying that this was the car for me but I have to say it’s not been a great ownership experience so far, although a lot of that is to do with the dealer and the particular car, not the Stinger in general. Buying an in-warranty car from a main dealer I figured I’d be pretty safe, but every time I drive the car I find something else not right with it. Some of this I’m just annoyed at myself for not noticing when I viewed the car, but some of this is stuff that the dealer had hidden or was done to the car between me seeing it and it being delivered, which is the kind of thing you’d expect from shady used car types, not a main dealer franchise.

I’m pretty much 50/50 right now on whether I keep the car and try to make the most of it or cut my losses and take the hit on trading it in for something else. Hoping the community can inject me with a bit of enthusiasm, as it’s running really low right now.

Many thanks,

MS

Hello I hope this gets a little traction, I just bought my 19 Kia stinger gt, I think want to get it around 400-450 who, I see alot of people talking about the jb4 piggy back tune but I have a really hard time trusting it. Any insight? Theres a reputable dyno shop near me I can get a dyno tune at. Should I go down that route?

I've been sort of compiling and validating some combinations. Criteria: avoiding poke, trying to find ways to improve on the stock look without compromising performance too much, etc. Seems like an okay start, might be cool if we could add to it (original in Excel has formulas and all that bit.) Thoughts?

My driver's side just went out. And I don't want to putvthe OE reflectors back in.

Good morning,

I've been waiting to have this exhaust installed since mid December when I received it and yesterday it all went down at a reputable shop I decided on. I went without the resonators and am very impressed by the tone of this exhaust and the theatrics it offers for the Stinger, especially ripping on the highway.

I had the entire exhaust welded, starting with a mid pipe flange delete. The mild steel of the OEM (2023) flange was heavily rusted and this was the way to go. It was mated up nicely with the cats and welded directly. I don't have a picture of the work done on this section.

I requested to have the quad exit pipes extended to match how the OEM setup was positioned in the bezels. I am very happy with how it looks, it is hard to tell that it is modified at first glance but if you know you know and that's exactly how I like it.

This exhaust has an intense low frequency drone right around 2.5K RPM - I knew this going in and it was the primary reason for extending the exit pipes.

The passenger side exhaust actuator connector wiring had to have its retainer clip disconnected to allow connection to the actuator when mounted on the MBRP catback. The wiring was pulled tight here and is just long enough to connect - I will probably need to extend the connector wiring on this side to accommodate my 11Mode controller.

Here are some pictures:

Anyone else have oil leaking from this location?

Went to do an oil change today, and notice oil dripping on the steering rack motor. seems to be either coming out of the top of the oil filter housing near the crank and or from where the oil cooler attaches to the filter housing.

Anyone else have this issue?

Car is a 2022 GT2 with 72,000 miles

I have the stinger gt and I’m thinking about going for intakes first then a dyno tune and an exhaust, will this net me the most power reliably?

My GT2 has been in storage for 5 months so I wanted to circulate the oil before starting the car. I pulled the 15A "sensor 1" fuse in the engine bay. It's described as the fuel pump fuse. Pushed the start button and the car started right up and ran great. No warning lights on the dash or anything. So, so much for circulating oil before starting.

Does anyone have a way of turning over the engine to circulate oil without starting it that actually works?

Hi folks, I'm excited to take her on the final roadtrip in my bucket list (NC500).

I'm planning on going in March and aiming to be back home before the kids are released from school.

I'm hoping to alternate between hotel and car camping for a balanced budget and experience. My only worry is getting a flat as I have patch kits but hoping I get signal for the AA incase I breakdown.

I really want to do the apple cross pass but given the size of the vehicle, I might skip.

Given the 300mile range I think I'm safe without a petrol can as I will fill up as much as I can between towns

Starting in Inverness, 7 days counter clockwise.

Let me know if you have any tips for this trip.
