Hello everybody,

I have a 2019 GT-line 2.0 RWD Stinger, 71k miles (115k km) that has all of the GT2 (3.3l) options except for the brembo brakes (yes, I have the adaptive suspension as well, it's a German version of the car with all of the options).

I see very high fuel usage during my daily commute and I did some tests at night on the highway, both in summer and winter. Premium tires for summer and winter, at the recommended pressure, no luggage / people in the car, warm engine and transmission:
- 110 km/h = 8.0l/100km // 69MPH = 29MPG (8th gear at 1850-1900 rpm)
- 130 km/h = 10l/100km // 82MPH = 24MPG (8th gear at 2150-2200 rpm)

This happens on ECO, Comfort and Sport mode.

This is tested exclusively on a straight highway road and it doesn't take into consideration the accelerations to get up to speed when entering the highway, it's strictly constant accelerator pedal and speed.

From what I could find on the forums, even the 3.3 Stinger gets better fuel economy when cruising like this. So something must be wrong with mine. I've drove another Stinger exactly like mine and that one had better fuel economy, on the same road I did the tests (29-30MPG at 85MPH // 8l/100km at 135km/h). Both cars have the same ECU and TCU software version, the one after the GPF issue was fixed in the software, so it cannot be that popular GPF logic bug that was happening on early softwares.

- replaced the spark plugs, the old ones had around 30k km (20k miles) and were black (attached photo)
- I did a smoke test for the intake, no leaks detected.
- The fuel rail pressure stays around 20000 kpa (2900 psi).
- The O2 sensor reports fluctuations between 0.95 and 0.98, where 1 is stoichiometric A/F ratio and 2 is 100% oxygen and 0% fuel, so it reports just a bit rich mixture, too small I think to count. Also the other Stinger that I drove had the same values and not the consumption issue.
- LTFT stayed at 4.5% and STFT stayed around -1% to 1%
- intake manifold absolute pressure was at 97-100kpa
- timing advance between 15 and 18 degrees
- cat 1 temp 780°C and cat 2 temp 680°C
- engine coolant stays around 100°C, engine oil is around the same temperature

It drives me crazy cause I use it as a daily and burns through my pocked with that fuel usage (20-25% more than it should). In mixed driving I get around 15l/100km (15MPG) without any hard accelerations.

I am planning to do the following hoping I might find the issue:
- replace the fuel pressure sensor (a few times I got the P0191 error and was showing fuel rail pressure at 500-600 kpa, so 10-40 times lower than normal, goes away after turning the engine off and on again)
- try to see if the dealership can override the current ECU fuel map with the stock one, to make sure the previous owner did not try to tune it or anything
- replace the upstream O2 sensor
- take down the GPF and have it checked physically at a specialized service to make sure it is not clogged
- replace the MAP sensor
- replace the HPFP

If anyone can help me in this matter would be great!

Upcoming recall for Stingers with 3.3TT engines regarding the driver side turbo oil feed line potentially deteriorating overtime due to head and leaking oil.

This was one of the things I was afraid of happening to my car since it’s 160,000km without warranty.

I noticed what appears to be cracked insulation (photos below)
Anyone know what this is and if it's normal or needs to be repaired?

The Stinger is currently at the dealer and the inspection did not mention this at all.

Thanks!

Braulio is the man. Worked with me on multiple occassions, including getting me a brand new Stinger when mine had radio issues. No shit.

Mine had ~300 miles on it and the radio started turning itself off, I went in and they said they couldn't replicate the problem in the shop. Showed videos and they went out of their way to find me a ~50 mile Stinger from a different dealer. Same color. Same deal. Received it 3 days later tinted and clean.

Hi guys.
Couple of issues with my JB4.
I've ticked the auto connect option but every time I start the car it's not connecting, I hit the big green connect button and it hooks up immediately, just won't connect automatically.
Next, if I put it into map 1, when I next use the car it's in map 3 instead of staying in the last map setting.
Finally, I've been through the whole app and can't for the life of me find the page for setting the wiper stalk adjust settings, in fact I don't think my app has the option!
I've attached a picture of what I've seen of other owners.
Thanks for any help.

Hello all,

I'm looking to price a US modem for the stinger in topic line. I called Canada kia and they stated that since I am a US resident, I could contact local kia dealer and ask them to swap and install a US modem to connect my canadian stinger to US network. Said might have to have local dealership service manager talk to canadian district manager. Has anyone done this, if so how much did it cost. Just trying to see if worth the price or not to have the connected features.

I have contacted my local dealership and they are looking into it.

Thanks.

Just finished up my head studs, got my first start up which was rough. However I assumed it was just air in the fuel system. I took it for my first drive and I wasnt making boost, and it felt extremely sluggish. I went and fueled up because I was low and I though that might help purge any air from the fuel system. After I got fuel, I started the car and thats when I got the p0087 code aka "fuel rail pressure too low". I did install high flow downpipes, paired with the catless secondary downpipes, could it be just a tuning issue with the increased airflow because I am on a stock tune at the moment. I also found a glass cartridge fuse under my car, Im really not sure if it is even from the car but I will attach photos of it. I know this might sound like a jumbled mess but any feedback is greatly appreciated.
