SC300 "Completed" but LH Turbo Line is leaking! Did I get pencil-whipped?

[RickyV]

Hey everyone, looking for some eyes on this.

I have a 2022 Stinger GT i bought 2 months ago with 65K on the clock, and I recently had Kia Corporate check my VIN and they confirmed that the SC300 (Turbo Oil Feed Pipe) recall was marked as "Completed" in May 2024. I had seen the leak there, but they said it was done. So i put up the car again to check to see if the line was actually replaced.

I have noticed some oil loss outside the usual 1 quart per 4K miles or so...(about 3/4 quart extra loss in a few weeks). Here is what I found:

1. The LH Turbo line is not a braided or reinforced line, it looks like standard black rubber.
2. There is active seepage right at the bracket/crimp connection near the turbo.
3. The bolts have green paint markings on them, but the hose itself looks original and is definitely failing

So i have to ask those in the know-

• For those who had SC300 done, what does the official Kia replacement hose actually look like? Is it supposed to be a different material than the passenger side?
• Has anyone else dealt with a dealer "marking" the bolts with paint but not actually swapping the pipe?
• Since the recall is marked "Closed" in the system, how do I get a second dealer to redo it properly under the safety mandate?

I’m supposed to drive this car 2 hours to Massachusetts this week. I’ve topped off the oil, but I’m pissed that a "completed" safety recall is currently leaking. To me, it doesnt look like it was even done but i could be wrong. But if Kia just ignored the repair and marked it done anyway i wont stop until they fix it..Thanks everyone!!!

This is very weird. I've never heard of the oil feed line to the LH turbo, or RH either, being "rubber" at any point. The temperature would make this impossible? What do I know? Now I am just confused by your post.

edit to add, the "inner tube" is rubber, but the outer layer is braided stainless steel. Where is your braided stainless steel in any of your pics? Are you showing the actual feed pipe or something else?

The SC300 recall does not use an exposed stainless braided line like aftermarket turbo feeds. The OEM LH turbo oil feed assembly uses a rubber inner hose with a heat-resistant outer sleeve and crimped fittings.
The recall replaces the hose/pipe assembly at the turbo side bracket which is exactly where the seepage is visible in my photos. This recall addresses seepage, not only active spraying, and many documented failures begin this way.

Thanks for the details. On the 7th Proximo my GT1 is getting inspected to find "an oil leak", which the multi-point inspection at the dealer a week ago exposed. There was no info on the source of the "leak", and the guy looking over the computer results said it looked more like "sweating" than dripping. There are no drips in my driveway/carport. But given the recall and age of my car, MY18, over 80K miles, Ima suspicious that the time has arrived to do that recall. I don't want to! But sometimes we are not given that choice if we don't want to court bigger disaster than putting our cars into the hands of KIA "techs". Ha hah.

I'm also not clear on what I'm looking at, do you have some zoomed out pictures? The third one does not look like the turbo, it looks like the wastegate actuator, except that the finned portion would be black instead of silver, and there's no rubber line on the WG actuators.

Fair question it was tight area and bad angles make it confusing. I only have ramps right now and it was hard to get under the car. The photos are taken from underneath, looking up at the LH turbo oil feed line and bracket, not the wastegate actuator. The wastegate actuator is a sealed mechanical unit and does not have rubber oil lines or oil seepage from what i have researched. The seepage shown is occurring at the oil feed hose crimp/bracket area, which is the failure point addressed by the SC300 recall. I verified the surrounding components (WG actuator, turbo housing, oil filter housing, adjacent hard lines) and they are dry. I can grab wider reference photos if needed, but this is the oil feed assembly, not the actuator. However i am new to the Stinger and dumped a 2002 Acura TL Type S for this car so a 20 year jump in tech has been a real eye opener. I used a high powered flashlight and looked at everything i could see with the underpanels off to make sure the leak wasnt coming from somewhere else and traveling.

That sweating description is exactly how a lot of these start. No drips, no driveway spots, just oil film at the crimp/bracket area. That’s actually the failure mode SC300 was written for before it turns into spraying on the exhaust. If they already flagged it visually, I’d strongly recommend having the recall done sooner rather than later. It’s one of those cases where waiting doesn’t buy you much upside, especially once heat cycles and mileage stack up. Biggest advice: make sure they actually replace the oil feed assembly and don’t just inspect and mark like i suspect Kia did with my car. Ask for the RO to list the updated part number after the work. That way you know it was physically done and not just documented.
