NHTSA Complaint #11609185 — 2023 KIA EV6

My Kia EV6, AWD Wind has the exact problem described in this Ionic 5 video, [XXX] , which addresses your TSB 24-EV-003H. It appears my EV6 uses the same electric oil pump (EOP) as the Ionic 5, so I am not sure why the EV6 was not included in your TSB? The first 14 months I owned my car, I loved it, then in June after I started driving for 45 to 60 mins, the car ride started becoming rough or unsmooth. After researching it on the Internet and purchasing some diagnostic tools, I figured out, that when I start driving the car there is a demand signal for the EOP but the pump has no rpm, no torque and no DC current. Depending on driving conditions, it appears the rear motor stops propelling the car when it reaches 190 to 205 degrees and the front motor kicks in to do all the propulsion. Under the front motor propulsion, the car has a definite “lag” in responsiveness which I consider extremely unsafe as I expect to get an instantaneous response when I step on the accelerator not a lethargic response with no “zip”. It is similar to the difference between a turbojet engine and a turbofan engine. It has been to my Kia dealership’s service dept where they told me they duplicated the the switch from the rear to the front motor but after talking to Kia this condition was “normal” as the computer calculated this was the most efficient operation of the car I said that was BS and asked them if they checked the oil pump and was told yes. Bottom line, it’s the same EOP as the Ionic 5 and the EV6 has the same problems with it except there is no displayed fault code so Kia fails to acknowledge the problem. Also, based on what I see when the motors switch, the on board screen display shows the front motor with 5-7 bars of whatever the measurement is and the rear motor has only 1 or 0 bars but the OBD data shows both motors with the same rpm? Three EV6 problems: EOP inoperative, no fault code, data disconnect (OBD vs displayed data). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
