2025 Kia K5 Reliability Score & Common Problems

Owners report frequent issues with the 2025 Kia K5's power train, particularly hard shifting at low speeds. Complaints commonly describe an extremely hard, head-jerking shift during the first drive of the day, especially after the vehicle has been parked for an extended period. This issue typically resolves once the vehicle has warmed up. The problem is noted to occur in vehicles with mileage ranging from the initial 0 miles up to approximately 3000 miles. In addition, one owner describes a failure to shift gears while accelerating, leading to a near-miss incident, and another reports a complete power loss while driving at 40 mph, though the vehicle restarted shortly after. These issues have led to two reported injuries, highlighting potential safety implications for prospective buyers.

Owners report two distinct visibility issues with the 2025 Kia K5. The first involves the panoramic sunroof shattering without any apparent impact, described as a loud noise similar to a gunshot, with the glass breaking upward and collapsing into small pieces. The second issue involves intermittent windshield wiper failure, where the wipers do not activate during rain or when using the sprayer function. This problem is noted in a vehicle with less than 10,000 miles and has resulted in visibility obstruction. Both issues pose safety implications, with potential for injury from falling glass and reduced visibility during adverse weather conditions.

Owners of the 2025 Kia K5 report issues related to the wheels, particularly with OEM Pirelli tires and the TPMS system. One owner describes a tire blowout at 55 mph with no visible puncture, occurring at approximately 6,500 miles, which could indicate a potential safety concern due to the sudden nature of the failure. Another owner reports repeated malfunctions of the Tire Pressure Monitoring System (TPMS), with the warning light reappearing at around 3,125 miles after an initial repair. These complaints highlight possible reliability issues with both tire integrity and TPMS functionality, which prospective buyers may want to consider.

Owners of the 2025 Kia K5 report issues with airbag deployment, particularly in crash situations. One complaint describes a collision with a cow where no airbags deployed despite significant impact to the front driver's side, suggesting a potential failure in the airbag system. Another owner involved in an accident reports experiencing prior vehicle malfunctions such as screen reboots and temporary power loss, though the connection to the airbag system is not directly stated. Both complaints involve crashes, and one reports an injury, highlighting potential safety implications for prospective buyers. No specific mileage is mentioned, but the incidents suggest concerns with crash-related safety features.
