Any update from KIA?

my MY16 SoulEV has been making that whaling noise when backing up for over a year as well. When i told the service guy at the dealership he said it was "normal". I also mentioned the clicking noise from braking at slower speed (like just before coming to a stop) and the answer was "normal" as well.

I called Kia after not getting a response after 1 week from my email which was assigned a case number. I was told they cannot contact Kia directly to get the answer regarding the 12V battery effecting the parking brake failing to disengage. The CSR told me that I should call or go to another dealer or two and get a second opinion to check if the low 12V battery can cause issues. She said they are the experts that talk to Kia directly for any service repair help. Since I bought my EV used, I wasn't as familiar with the car from the beginning and the change in how it was driving. I did call the dealer and ask about the noise a couple months before taking it in and was told it was probably dust on the brakes. What I have noticed since the repair is when I back up now there is no noise and the car rolls freely in reverse once I take my foot off the brake. Before the repair, I needed to press the gas pedal before the car would roll out of the garage. I've noticed the same thing going forward too. The car rolls easier forward than before once I remove my foot from the brake. I plan on following up further but I'm short on time at the moment and the dealers are 45min away. Big hassle. I will definitely pay attention to any noise I hear backing up and follow up immediately. Also, I hear a clicking noise at the front of the car while braking. It has done that since I bought the car and I thought it was normal.

That is rubbish. When the car is turned on the DC/DC converter will be providing 12V power to charge the 12V battery and run all the 12V electrics including the parking brake. A low 12v battery will only affect things like lock/unlock and the initial turning on of the car. Once the car is turned on then the DC/DC converter is powering everything.


I completely agree with @notfred, ask them to put that in written, signed and stamped. You will notice a difference in their tone.

Regarding a 12V Auxiliary battery (under the hood) causing non-full disengagement of the EPB:

Yes, the DC to DC converter in theory does deliver the 14.4 volts to keep the lead acid house battery charged, but the dynamic timing of the delivered pulse for retracting the EPB (Electronic Parking Brake) vs the wake-up period of said DC to DC converter may not fully jive with good engineering practices.

If the lead acid battery is nearing the end of its useful life (and if the Kia engineer in charge of this sub-system didn't fully vet their design) then the "release" parking brake pulse may not FULLY do its job (obviously, a bad scenario for the car owners).

Remember, only a few engineers are excellent; some do VERY well, most are average, and the rest make many mistakes... (sadly) THIS IS the human experience we all must endure.

I'm not sure what's transpired for these affected owners, but I'm interested to hear any feedback they and others can offer.

I have both of these sounds in my new to me 2016 Soul EV. 40k miles. The 12V battery sounds plausible to me. I had a weird gremlin on the dash where the GOM bars were flickering. It had the feeling of a battery issue

I took my car to another dealer for a 2nd opinion not long after the first dealer said the rotors were damaged. The 2nd dealer said everything looked great and they didn't see any damage to the rotors. They also had no idea what was making the whale noise. I gave up at that point. I have gotten a new battery and I just heard the noise again today. Not sure if the cool, rainy weather is causing it to be noisy again.
I recently went back to my nearest dealer (1st dealer) to get the software upgrade so the car could not roll backward while parked and turned off. This happened to me once about 6 months ago. I parked the car in the garage, took groceries into the house and returned to the car to see it roll backward about 3 feet and jerk to a stop. I always use my parking brake but wondered if I could have pulled on the brake then put it in park thus going through reverse which would disengage the brake. Either way, it was in park with the charging door open. I Contacted the NHTSA and got several calls from Kia. Took my car to the dealer and left it so they could go through a long testing process. Mechanics at the dealer thought I was nuts. Nothing found. I guess Kia decided they should at least upgrade the parking brake to engage automatically when the car is powered off. Anyhow, the service guy told me that when they got the notice regarding rolling in park, their mechanics went out to their electric Souls (older models) on the lot, put them in park and rolled the cars backward. Maybe the fix will stop that problem. It should have been done long ago.

The bottom sectors of the GOM flashing has been seen since the Soul EV first came out. It seems to be just a harmless bug in the GOM, not related to 12V battery. I've had it happen with a 12V battery that was fine.

Any idea if there is a way to test the 12V battery via OBDII scanner? I have a Bluetooth one. I don't know if it's really useful to load test since there is nothing to "crank" like with a gas car.

Load test is the only way to test a battery properly. It needs to be able to power the brake pump and lots of lights etc before the car is turned on and the DCDC converter can drive things.

You can always use the bluetooth dongle as a voltmeter to read the battery voltage https://stackoverflow.com/questions/545 ... sing-obd-2 but pay attention to whether you are measuring the battery or the DCDC converter.

Something like this is good. However, I have a suspicion that the battery monitor (black box on the +ve terminal) can cause false readings, so I would disconnect the +ve terminal before applying the meter.
