FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: ASSIST
Submitted by [XXX], Authorized Representative for the owner. The vehicle has a physical defect in the ADAS forward-facing camera bracket caused by a dealer-concealed repair using industrial silicone adhesive. The bracket is now visibly sagging, causing misalignment that leads to intermittent Automatic Emergency Braking (AEB) failure. Critically, the vehicle’s computer does NOT illuminate a warning light for this physical displacement ('silent failure'), posing a severe crash risk. An undisclosed aftermarket GPS tracker was also found installed, which is pending contract review. A third-party inspection report titled 'Repurchase Inspection (Silicon at Rearview Mirror)' confirms the non-OEM adhesive and physical sag. The dealer has refused to provide a safe replacement vehicle. This defect stems from a non-OEM repair performed prior to sale. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER, LANE DEPARTURE: ASSIST, LANE DEPARTURE: WARNING
Driver awareness warning goes off frequently. There is no way to desensitize it. As a result warnings are ignored. Dealer and manufacturer says there is not way to prevent this issue.

ENGINE, ELECTRICAL SYSTEM
The display is shows a "Check Oil Level" error. It comes on then goes off regularly. I have verified that the oil level is OK. Took it into the dealer and he said that this is a common issue and a software fix is coming. The car only has less than 2K miles. I depend on the engine displaying error messages, but they need to be real ones. Online complaints indicate that this is a common error and there seems to be no fix.

ELECTRICAL SYSTEM
Kia has a known wiring‑harness defect that causes the low engine oil sensor to trigger incorrectly. Despite this, there has been no recall, and new vehicles are still being sold with the issue. The wiring harness is now on back order, leaving me without a car for weeks or longer. The vehicle has plenty of oil, and the dealership confirmed there are no engine problems, yet the warning light keeps coming back because of the faulty harness. This happened 1 day after buying this car new from the dealership lot.

UNKNOWN OR OTHER
My vehicle is 3 months old with only 3300 miles on it at the time this happened. I was driving on the interstate near on Saturday, January 17th, 2026. It was reasonably cold outside, and of course I had the heater on set to 70. My panoramic moonroof glass was closed, but the shade was open. My glass randomly exploded outward leaving a major hole in the glass. Glass shattered and sprinkled inside the vehicle while I was driving. After pulling over to identify what happened, I realized that the moonroof exploded outward from the vehicle.

UNKNOWN OR OTHER
Had the sunroof sunshade open, and the sunroof has exploded spontaneously out of nowhere. Since i had the sunshade open, the glass pieces went all over me and my wife, it had first scared us cause it was like a gun being fired off in the car, and i could've gotten into an accident. No. the car hasn’t been seen by the dealership. Theres has been many reports about this issue, me personally im in a group and theres a few people on there that this has happened to. No warning before it happened, there was no sign of impact. looks like it just spontaneously exploded outwards.
