NHTSA Preliminary Evaluation PE25004 - closed, opened 2025-04-29 and involving the KIA KIA.
Among 2,329 NHTSA Preliminary Evaluation files in PlainCars' ODI extract, this record (PE25004) is one published case in that type class , and one of 38 investigation files attributed to KIA.
NHTSA investigation PE25004 is a Preliminary Evaluation opened on 2025-04-29 and currently closed. The subject of record is KIA KIA, which places this file inside the Office of Defects Investigation queue for KIA. Latest activity on this investigation was logged on 2026-03-11 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE25004 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "On April 29, 2025, NHTSA’s Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE25004) to investigate inoperative windshield wipers in model year (MY) 2024-2025 Kia EV9 vehicles. The complaints rep..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time. Related KIA files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
On April 29, 2025, NHTSA’s Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE25004) to investigate inoperative windshield wipers in model year (MY) 2024-2025 Kia EV9 vehicles. The complaints report windshield wipers that malfunction while driving, when snow and/or ice accumulates on or at the bottom of the windshield or in the cowl. ODI further received videos and photographs that depict relatively small amounts of snow and/or ice accumulation that leads to the wipers’ malfunction. Inoperative windshield wipers could reduce driver visibility during inclement weather and increase the risk of a crash. ODI identified 7 Vehicle Owners Questionnaires (VOQs) related to this investigation. Five VOQs describe inoperative windshield wipers due to snow and/or ice accumulation. Two other VOQs describe other malfunctioning windshield wipers including snow build-up on the blades and an odor of overheating. The wipers are equipped with thermal overload protection designed to limit overheating of the wiper motor. Further, consumers describe windshield wipers that temporarily stop working when they are not able to clear the windshield. This may happen when the wipers stop before the parked position in the cowl at the bottom of the windshield. In January 2026, Kia informed ODI that it will conduct a Product Improvement Campaign with owner notification for approximately 47,000 MY 2024-2026 EV9 vehicles. The campaign includes a hardware change to the passenger-side wiper arm and an Owner’s Manual revision. The replacement wiper arm will be a different shape and angle that increase the space/clearance between the cowl and the wiper. The Owner’s Manual revision will emphasize the importance of snow removal prior to driving, and it will recommend that drivers place the wipers in service mode when the vehicle is parked outdoors, and snow is forecasted. In addition, Kia is planning to develop pop-up cluster warnings that will be temperature-dependent, and they wil
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
