The Door Warning Sound in My 2024 Kia Picanto Is Consistent.

Hello! My Kia has just gone over 3,000 miles and is due for its service at the end of the month. It's the second one in a row.

On occasion, the door warning tone has failed to activate. Whether the car is in drive, neutral, or reverse, or if the lights are on or off, it appears to function.

According to Kia, they can perform a diagnostic on the vehicle, but there will be a fee. Even if they don't find a problem, I will still be charged.

Anything you can tell me would help a lot.

It is common practice to charge for diagnostic time; however, if a fault is found and covered by warranty, you will not be charged. If you're worried about the finances, you might want to consider enduring the fault until it becomes permanent. It can be quite challenging to diagnose intermittent faults because the car may not detect them when the fault codes are read because it thinks the fault is minor and happens intermittently.

Thanks, and there have been a few "intermittent faults" with the car, but they are manageable and relatively minor.

Is this an issue with just one door, and does opening the door switch on the inside light? This is completely conjectural, but I'm wondering if lubricating the door jamb switch might fix it.

Thanks! I've only tested it on the underwater side, but the door still turns on the inside light. I can verify if the passenger side exhibits the identical behaviour.
