The EWP Actual & Command are equal, I believe this is the front EOP, which is operating without issue.

Nope, the EWP is for water coolant in the electronic units and/or battery pack.

Good to know, what is the code for the front oil cooler? The parts manual shows the same part number for the front and rear Electric Oil Pumps.

I got my Ioniq 6 back today. The Hyundai tech swapped out the electric oil pump. It is now showing torque/RPMs on Car Scanner, so I'm fairly confident they've fixed the issue.

The power-problem with my EV6 is solved!! Kia Netherlands and the Kia engineers at the factory in South Korea monitored the data I made with a delogtool (by my dealer) and ordered the dealer to change the Electric Oil Pump (EOP). I made several test drives and no turtle anymore.

Yep. EOP is calling for RPM and getting nothing. Takes about an hour to get to like 215F when it shuts down. I posted some recorded plots on Reddit along with some videos. Those with AWD drive drive quite normally, but with very little power, using the FWD motor. Put the car into SNOW mode and it works okay enough to get to a destination.

That sounds familiar. Snow mode will eliminate the lurching that occurs when acceleration is attempted, but won't help with the loss of the 270hp rear motor. I posted a complaint in the NHTSA website as did someone else that has our experience. Were you able to have the EOP replaced? Are you still dealing with this issue?

 

[no-gas]

Did anyone read the news that Hyundai/Kia is recalling several ICE models? EOP component related?

"The recall covers Hyundai 2023-2024 Palisade, 2023 Tucson, Sonata, Elantra, and Kona vehicles and 2023-2024 Seltos and 2023 Kia Soul, Sportage vehicles.
The Korean automakers said electronic controllers for the Idle Stop & Go oil pump assembly may contain damaged electrical components that can cause the pump to overheat. "

same issue here. dealership says theres no error code. been sitting there for a week. they are finally going to take it for a hour long 80 mph drive to try to duplicate the problem.

 

[bulnesjose206]

The car is still with the dealer. I told them to do exactly that. I live nearly an hour's drive away from the dealer.

Edit: The service department could not reproduce the issue. I asked if they'd checked the electric oil pump, and they claimed that they did. They insist that the car is "driveable" despite it losing power three times so far at Interstate speeds. I've opened a ticket with Hyundai Corporate, and we'll see where that goes.

I have same problem Ihave ticket also my car stay in the dealer for 6 week and still they cant fixed

 

[bulnesjose206]

Thanks for the information. Unfortunately my OBD2 reader wasn't available at the time, as I've been keeping it in my other car to diagnose an intermittent O2 sensor problem.

The service advisor at the dealer keeps claiming that since it doesn't throw an error code, there's nothing wrong. Except it has died on me on the Interstate three times now. I don't care if there's no code -- the car isn't safe to drive. I'm not taking it back until they actually reproduce the issue, or figure out exactly what's wrong and fix it.

He blew off my suggestion about the electric oil pump with "we have the top techs in the country, I'm sure they looked at everything". I told him to ask the tech what the commanded oil pump speed was versus the actual when driving on the highway. We'll see what they say.

I'm going to escalate to the manager, and I guess corporate if I don't get a satisfactory response.

If you go to the dealer for same problem star claim for Lemon Law

We are going through this exact situation right now with out 2023 Ioniq 5 SEL. How did you get the dealership to believe you and help you? Ours is saying they drove our car and it’s fine. We told them it only happens after 60 miles of driving and they won’t drive it that far. to The people that had this happen to them, were they able to fix your car?

Use carscanner app and start recording screen with mentioned pids set on the screen.
And this will be enough to provide evidence what is happening when vehicle is used for extended period of time and how oil pump is stopping to work without any errors popping up.

 

[rlane]

I am having the same issue with my 2023 Ioniq5 after 60 minutes of driving. The dealer wants me to trade for a 2024. Anyone know if the issue solved for 2024?

Care to provide more information on this logging tool, if you have pictures would be helpful, wanna see if it is same as my tool?

 

[zooomart]

2023 I5 Limited no issues at 6k miles. I say this not to minimize the rear motor oil cooler issue you clearly experienced. Only to suggest this major fault is not common

 

[samba1x]

I recentl had a similar issue with the EOP on my IONIQ6. This time, the car gave code DTC-P1C2900. Details here: https://www.ioniqforum.com/threads/ioniq-6-trouble-code-dtc-p1c2900.48750/

i took a video of it happening while i was driving. I just got my car back, total of 2 months with 2 different dealerships. They did NOT change the EOP. Invoice shows they changed the VCMS, so I doubt its fixed. I will be going on a road trip to test the car. also I've hired a lemon lawyer so we'll see what happens.

If using carscanner app
Watch over EOP pids
Commanded and actual rpm
EOP current
EOP torque.
All of them should be running when vehicle is in motion for RWD.
Switch to Eco mode and take hilly terrain at 70 MPH or faster.
Also set pid for RWD stator temperature.
If not familiar with values post screen shots and i will help you out.
Provide with each screen shot, outside temperature, set speed, road conditions and if RWD is turning off and running only FWD if AWD model.
