5/5 Overall
NHTSA 5-Star Safety Rating
Complaints about the 2024 Kia K5 cluster most heavily around structural issues and the engine and fuel system. On the structural side, owners describe trim and exterior pieces separating from the vehicle while driving, interior seating components lifting or becoming loose, and fitment problems that suggest assembly quality concerns. Fuel system reports are notable: multiple owners describe the fuel tank swelling under pressure, gas being forced back out of the filler neck, and the fuel door area deforming enough that it won't close properly. A few owners also mention sensor malfunctions accompanying the fuel tank issue. Engine and fuel complaints together make the powertrain the other focal point. The electrical system draws a smaller share of reports. One owner documents unusually rapid brake pad and rotor wear, going through multiple replacement sets before 40,000 miles, though that pattern appears in a single detailed report rather than across several complaints.
