There is a defect with the WINDSHIELD glass. The windshield glass gives off an audible "SNAP" or "POP" noise when the inside of the windshield glass experiences a stress crack. This is not a crack that can be felt from the inside, or the outside. It is actually inside the glass and it can only be seen when the sun hits the windshield a certain way. Eventually failure of the windshield is imminent. The windshield glass internally fractures under normal driving conditions. It happens commonly, and intermittently, probably at least once per …

Recall history

2 distinct campaigns affect this selection. Announcement dates below are different from vehicle model years. A campaign may cover multiple years.

25V548000 · Engine And Engine Cooling:Critical Fasteners

Reported: 2025-08-25 (August 25, 2025)

Kia America, Inc. (Kia) is recalling certain 2025 K4 and Sorento vehicles. The connecting rod bolts in the engine may have been improperly tightened, which can cause a loss of drive power.

Consequence: A loss of drive power increases the risk of a crash.

Remedy: Dealers will replace the sub engine assembly, free of charge. Owner notification letters are expected to be mailed September 12, 2025. Owners may contact Kia customer service at 800-333-4542. Kia's number for this recall is SC349.

Consequence: An instrument panel display that fails to show critical safety information, such as the speedometer, tire pressure, or warning lights, increases the risk of a crash.

Remedy: The instrument panel display software will be updated over-the-air (OTA) or by a dealer, free of charge. Owner notification letters are expected to be mailed March 26, 2026. Owners may contact Kia Customer Service at 1-800-333-4542. Kia's number for this recall is SC361.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.

Observation windowFirst model yearSecond model year

No selected model years have a complete observation window. Choose an eligible year or a shorter window.

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
