I was driving my 2017 Sonata Hybrid SE into work and parked in the parking lot. When I went back out to go to lunch I tried to unlock my car with the smart key. The car beeped twice but did not unlock. I tried again and same result 2 rapid beeps but still locked. I tried to hit the lock button and I heard nothing. I opened the car manually with the physical key and attempted to start the car up. It started to turn on but then dash lit up with a "Stop car and check brakes" warning and the ABS, ESC, and parking brake warnings came up and my car wouldn't start. I started to have some electrical issues as well. The driver window would only go down when the door was opened when I closed the door the windows would not move. The passenger window seem to be working okay. Then there's the fob, when I would hit the lock I heard nothing but the unlock would make the car beep but not unlock. I read people having somewhat similar issues but seemed at some point their cars would started up after 30 mins to an hour. That wasn't the case with mine. I went back to work and left it in the parking lot for about 4 hours and tried again. I was getting the same error and still car wouldn't start. I started to notice the power fading so I had a coworker give me a jump start and that didn't work either. I decided to take my 12V battery out and get it fully charged and tested. After getting it charged and tested being told it tested good I put in back in the vehicle and tried to start it up. The power didn't seem like it was fading anymore and the windows were going up at normal speed but still acting electrically weird. At this point I thought it might be a faulty power relay assembly in the hybrid battery cause the issue with the brakes and the electrical system so I have my car towed into the Hyundai Dealership.
After 2 days my service manager tells me I have a bad 12V battery and I need to replace it and they have one for around $300. I tell them before I brought the car in I had the battery tested and it tested good I was getting 600 CCA and 13.65V. I even had a multimeter to test it myself on top of auto part store test. They insisted the battery was bad and needed to be replaced. I just wanted to fix the issue and get my car back as I didn't have another car and wasn't given a rental or loaner. I told them fine but I'll bring a new battery for you. I found the exact battery that day and paid $150 brought it in for them to switch out.
The next day I don't hear anything from them so I call in late in the day and they tell me the car Is still giving the errors and not starting up and they're running test to see what's wrong, I'm not surprised. About 4 days and a bad review later I'm told by the dealership that they found 2 connectors unplugged. The ABS connector and the Active air flap connector.
This is mind boggling to me cause I can't for the life of me figure out why these 2 connectors would be unplugged. The only thing I can think of is an oil change that I got 4000 miles ago or a State inspection and emission test I got a week and a half before the issue popped up. I don't see anyone disconnecting those for an oil change and the State inspection should mostly be visual. I don't see them disconnecting the ABS and AAF and forgetting to plug them back in. It's possible but I just don't see that happening.
I see the more likely scenario as them unplugging those connectors trying to diagnose the issue as they told me they had several Hybrid techs working on it cause they couldn't figure what the issue was and maybe one tech did it and didn't communicate that to the others but that's just me trying to make sense of all this. And even if that was the case would that also cause they fob issue and the electrical issues? I can see the warning and the system not starting but I don't see it affecting the electrical that way. I'm just frustrated at this point cause it's been almost 2 weeks and I still don't have my car and nothing is making sense.
