3.3TT Low Oil Pressure

[KDM Harley]

I have the same issue with a 2019 Kia Sorento ex 3.3 The dealer quoted me 2,000 in parts and labor to change out the oil pressure switch. Mine is out of warranty wit 130,000. miles on it. However the problem has been around for awhile. They even extended the warranty for the switch to 10 years 150,000 miles but only up to 2018 model year. I'm going to request a meeting with the dealer principle on the matter and get it covered by Kia or I'm going public with the issue witch would cost Kia a shit ton of money.

I have the same issue, I’ll go public with you, let me know!

Does anybody know where is this switch located? The manual is showing that you have to remove alternator to get to it. But I am guessing it's for 2.0, since $3000+ won't make sense than. Some YouTube videos are showing NA 3.3 kia engines with this switch underneath injectors fuel rails. Just curious.

Under the intake (see attached)

Thank you! Still, $3000 for that??? I guess, I will just replace mine as PM, next time I am cleaning intake valves. I just don't understand these labor prices!! Edit: it is under injectors rails in the back of the engine, right?

Did some more digging. And looks like that sensor is in front of the engine, sitting right next to "water pump main pipe". So the main question, is it possible to remove that sensor without taking that water pipe out. Because, to remove water pipe, you need to remove thermostat housing, and that might require.....dropping the engine. That might explain $3000+ in labor. Absolutely idiotic design, but is in line with modern engineering.

I’m having this problem too, I’m too broke to replace the sensor so I’m just riding on it.

I want to talk to the certified stinger specialist and see if we can get that extended warranty since it’s a 2018 lambda ii engine with the exact same sensor problem as the other models that have that engine and share the same year. Those models got full extended warranty coverage up to 160,000 and 16 years.

Ask him, if it's possible to remove the sensor without taking water line out. That will make all the difference.

Yeah I’ll ask him. If I can do it myself I will. The part is only about $90. Here’s this on that warrenty extension:

That's for different car. I don't see how you can apply it to stinger.

Because they are equipped with the same engine. But without the turbos. It’s the Lambda ii GDI.

It seems to be a common issue and if the Stinger was the flagship vehicle they should honor that engine over those other models with that engine.

Same Engine, Same Sensor problem, why leave the stinger out of the warranty extension clause?

That’s the question.

Finally got this red oil pressure warning light come up on my dash at 102K miles. Took it to my mechanic and he said its the oil sensor. Looks like its doable by removing the intake valve cover, upper and lower manifolds, and the fuel rail lines.

Here is a video of a similar engine.

Its a tight squeeze with a 22mm wobbly socket to get to the sensor as its closer to the main water line going across but certainly doable. My mechanic said he can do it in 3 hours tops. He will also try to clean the carbon deposits on my intake valves while the intake valve covers are removed. I've put in an order for the sensor (947513C000) through Hyundai as it seem to be cheaper there compared to Kia dealerships/wholesalers. The sensor just costs CAD$50. Will get this job done next week.

Awesome

Please do share the results.

Would be awesome if he could take a picture or 2 for the community. But that might be asking too much.

How much did he charge you to replace it + the carbon clean up?

I’m the second owner of my stinger and out of warranty, I will probably go that route as well when the time comes plus the carbon deposit cleaning, while the valves are exposed seems like a good move.

 

[KDM Harley]

I took it into my mechanic, he said it’s a failing sensor. He said it’s fine don’t worry about it. The light hasn’t come on since.

I’m by no means a mechanic so I thoroughly enjoy how-to videos. I just read through this thread and if this seems to be a common failure, I wouldn’t mind having a video tutorial of this repair (save some money down the road I got 29k on my 2020 so I’m hoping it’ll be a few years lol.)

Are you close with your mechanic that he would be down to record the process of this oil sensor replacement? If not, I understand maybe someone will eventually make a video

I am still waiting for the ordered part to arrive. Unfortunately, It's on backorder everywhere and will take about 3 weeks. Interestingly, the weather warmed up a bit today to -1 celcius and lo and behold, the red light does not show up at all. It makes me to believe that colder temperatures have an effect on the oil which in turn affects these sensors, especially on high mileage vehicles. I will continue to monitor until the sensor arrives. There is nothing to worry about if you don't idle your engine too much.

 

[Ohiocruiser]

Good to know, it's doable without removing main water line. Will definitely do it as pm job, next time I clean the valves.

Isn't this just a hypothesis this far?

From the video he posted, looks like they replaced it without removing that line. But the video is kind of crappy to be 100% sure. Hopefully we'll get an update on it.
