NHTSA Complaint #11556250 — 2020 KIA TELLURIDE

This started in July/August. I went in to get into my car and noticed that although my car was making the sound of unlocking, it wasn’t unlocking. Neither the key fob or pressing the button on the door handle would unlock my car. I manually used the key to get in. Once I got in, I had a rear collision warning on my dash and was unable to shift from park. I overrode the shift mechanism and took it to a mechanic. They hooked it up to a reader and was tracking down the error when all of sudden the error code disappeared, and they were unable to progress. I left there and drove to work without issues. Two days later (Saturday) it happened again. I disconnected the negative battery cable and waited a few minutes before I hooked it back up. It was fine for about a month and then it started happening again. This time I tried the battery cable again and it worked for a while, but it started to happen more regularly. I took it to a Kia dealer but they were unable to replicate it. They said if it happens again record it and send a the video. Two days later it happened, and I sent them a video. I took my car back to the dealer and it has been there 11/9. In between visits, it happened, and I overrode the shift mechanism and I noticed my dash lights were almost out as well as the other issues. I believe I know what the issue is. I noticed this only happens when it’s cool in the early morning and then, when the sun comes up, there is an abundance of moisture on the inside windshield. I believe that heavy moisture is shorting out the electronics in my dash. I’ve never had an issue when it rains or midday. It’s probably why this has been so noticeable in the fall early winter. We have lots of mornings in the 30’s and they quickly warm up when the sun comes out. I have read some online forums that talk about the condensation issue with the Kia Telluride. I haven’t found any that talks about the electronic issue however.
