Is there a fix? Manufacturer service bulletins

THESE WATER DROPLETS ARE MORE VISIBLE AT NIGHT AND THE QUANTITY OF WATER PRESENT IS MORE THAN JUST A THIN FILM OF CONDENSATION WHICH MAY NOT EASILY EVAPORATE. THIS CONCERN IS CAUSED BY A GAP BETWEEN THE TAIL LAMP HOUSING GASKET AND VEHICLE BODY WHICH ALLOWS WATER TO INFILTRATE INTO THE TAIL LAMP. TO RESOLVE THIS CONCERN, ORDER NEW FOAM GASKETS AND INSTALL THEM BETWEEN THE LEFT AND RIGHT TAIL LAMPS AS REQUIRED AND THE BODY OF THE VEHICLE.

The failure pattern owners describe
Owners describe a recurring pattern: headlights that flicker or shut off completely while driving at night, sometimes triggered by switching to high beam or activating the turn signal. One owner's lights went dark for three to five seconds at highway speed—dangerous and unpredictable. A dealer told one owner they'd fixed the same failure multiple times ($238 repair cited) but no recall exists. Another owner reports the lights won't turn on at all.
Tail light problems run from bulbs that fail repeatedly within a year despite good fuses, to defective gaskets that let water into the trunk and kill both brake lights. Water pooling and mold signal a design flaw.
Dashboard and interior lights flicker during driving. Some owners find headlights self-activating at night when parked in auto mode, draining the battery. Brake lights fail to respond to pedal pressure while the ESC light comes on—bulbs and connections check out fine.
A blower motor connector burning smell at 80,000 miles ties in electrically. Front headlight lens covers are developing long cracks. Dealers acknowledge familiarity with these issues but say Kia's position is that the vehicles operate as designed. Most failures remain unrepaired.

What owners are reporting 1 most recent
Brake light failure on both tail lights. The problem started by finding mold in the trunk. This was caused by water pooling in the bottom space where the spare tire would go if it came with one. Water leaks were observed from both tail lights into the trunk. The culprit seems to be bad gaskets for the tail lights. The gaskets have cracks which let rain water through. The poor design of this part…
