2017 Kia Soul EV Electrical Problems

My car has had intermittent faults of codes P1B25 and P1CF2 and are showing check EV system on the dash. This happens after about 30-45 minutes of driving and then restarting the car. It has been identified that the power relay assembly needs to be replaced on the vehicle, which lives in the high voltage battery pack. However, Kia does not want to replace this under warranty , claiming that it is not an EV system component. I am not going to pay out of pocket for this repair as it goes against their own warranty information, but continuing to drive the car would be dangerous as it could drop HV power at any point.

The contact owns a 2017 Kia Soul EV. The contact stated that while driving at an undisclosed speed, there was an abnormal battery voltage warning displayed. The vehicle went into LIMP Mode. The contact stated that the battery failed to charge. Several unknown warning lights were illuminated. The message to “Pull Over Immediately” was displayed. The vehicle was taken to the local dealer, where it was diagnosed that an update, BMS, and wiring harness needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was towed back to the local dealer, where an unknown diagnosis and repair were performed. The manufacturer was contacted and opened a case. The failure mileage was approximately 50,000.

Application of the brakes causes complete vehicle shutdown along with message to check electrical system. Brakes appear to fail for a brief moment, then mechanical brakes kick in. Car has zero power until stopped and restarted. Problem is reproducible a high percentage of the time provided the brakes are pressed more than just lightly or briefly. At nearly full charge, this defect can also be triggered by just the engine brake (which is triggered every time your foot is taken off the accelerator). Appears to be an electrical short circuit of some type. Other faults occur upon application of power, shifting engine into low power or turtle mode at any level of battery charge.

The 2017 Kia Soul EV+ vehicle turned off coming down a steep hill (at the bottom of the steep hill is both a school bus stop and and entrance/exit to a condominium community). When the car shut off all power steering and power brakes were lost, making control of the vehicle very difficult and unsafe. The dealer reported finding a code for the battery overcharging but cleared the code and did not offer any explanation. This has happened multiple times including when I was videotaping the dash to document irregular discharge occurring from the battery. Similarly the vehicle will be driving fine (at any speed) and suddenly lose power and only go 20mph (known as limp mode), a very dangerous situation driving at highway speed and then trying to avoid an accident due to sudden vehicle deceleration. This problem started occurring after a Battery Management System patch was applied by the dealer for a Kia Recall related to battery safety (overheating and fire issue) in July 2023. Upon pickup from the dealer it was immediately evident the car still had the rapid battery discharge issue and this was further documented with Kia USA case #[XXX]. The next dealer was able to reproduce the excess power discharge problem in November and after 3 weeks I was told a battery replacement would be provided per the 10yr/100K warranty the vehicle carries (my vehicle has less than 50K on the odometer). Since November there is no time estimate on when the battery will be replaced. It would appear that the Battery Management System patch (applied to my car in July) and to many other Kia Soul EVs, somehow damages the battery as there are now hundreds of Kia Soul EVs awaiting battery replacement across both the United States and Canada and no promise of when a replacement battery will be forthcoming and it appears Kia has no solution for the BMS issue at this time. Kia says it will refund up to $39.40/day car rental cost AFTER the warranty work is completed (more $ out of my pocket)! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

This is an update of the below. I have had several email exchanges with Kia Customer Service. They contacted the dealer and report that they could not get a response from their own dealer! They said I could try another dealer if I want. I asked for a recommendation of a dealer that would be responsive and got no further communication. Meanwhile, my car continues to show low charging pattern, which the recall warns is a symptom of a fault. ====================================== Received an "Important Safety Recall" notice from Kia recall number 23v218 in May 2023. This indicates my Kia Soul EV by VIN. The notice warns of a possible short in the main battery that can cause a fire. The notice says Kia is working on a remedy and that another letter will follow when the remedy is ready. No second letter yet, as of 9/13/23. The recall notice states that if in the meantime owner experiences "incomplete high voltage battery charging, loss/fluctuating vehicle EV battery range" to seek assistance from nearest authorized Kia dealership. My vehicle experienced rapid decrease in range, down below 60% of the full range over a period of weeks. Most recently charging the vehicle (using two different chargers) causes the circuit breaker at my home to trip, something that has never happened before. I contacted Kia America by phone and email. They said I should take the car to the dealer. At the dealer I describe the problem, show the recall notice. They say they cannot execute a remedy and that in order to have the battery checked I need to leave the car with them indefinitely. Service said some cars have been waiting 6 weeks for a diagnostic. So I have a recall notice, my car is experiencing a warning symptom, and I cannot get the dealer or Kia to take reasonable action.

My 2017 KIA Soul EV battery has not been holding a full charge since the beginning of April. The dealer was notified in early May that the charges were seeming to cut off early & provided with a log of charging/driving. We waited, then were told that a replacement battery would be ordered, installed, & considered under warranty. Diagnostic tests were run, we were advised. We were told that the car was safe to drive, although with about 50% of the mileage available (50-51 miles). The final paperwork (vehicle registr.) copy was filed on May 18. Now we have received a safety recall notice. I am afraid to drive the car, having seen news of what loss of life can happen a fire breaks out while driving! My dealer has not offered me help with an interim rental car to date, although I have requested this several times, specifically yesterday - June 6, 2023. At this writing, I have been told that "the battery is on order, however, no specific info on shipment date or date expected" is available. "It will come on the barge," was the last statement, hard to believe in this day & age of electronic records. I have stopped driving the car, have talked with my insurance company, & will call the dealership again about the matter. I am most unsatisfied. I have a record of numerous calls back & forth with my KIA dealer, service dept. manager.
