2024 KIA EV9 Reliability Report

Owners report persistent steering vibration in the 2024 KIA EV9, particularly at highway speeds above 65 mph. Complaints frequently mention the steering wheel and center console shaking, with some noting that this issue persists despite multiple attempts at wheel balancing and alignment checks. Several owners describe additional symptoms, such as the vehicle weaving or fishtailing, especially when encountering bumps or uneven surfaces, raising concerns about control at high speeds. These issues appear soon after purchase, often within the first weeks of ownership, and some owners express safety concerns due to the potential for loss of control. Additionally, several reports indicate that the lane assist and active lane keeping functions behave erratically, either failing to disengage or disengaging without warning, which could lead to near collisions.

Owners report several issues with the power train of the 2024 KIA EV9, primarily involving sudden loss of power and unresponsiveness to accelerator inputs. Complaints frequently mention incidents where the vehicle becomes unresponsive, unable to shift gears, or fails to start, often accompanied by dashboard warnings of electrical system failures. A notable pattern includes ICCU failures and backordered parts causing extended repair times. Mileage is not consistently mentioned, but issues seem to arise relatively early in ownership. Safety implications are evident, as some owners describe the vehicle unexpectedly slowing or accelerating, posing risks in traffic.

Owners report several issues with the 2024 KIA EV9 related to vehicle speed control, particularly involving the adaptive cruise control system. Complaints frequently mention the vehicle unexpectedly accelerating to high speeds, sometimes over 95 mph, when there is no vehicle ahead within range. Additionally, multiple owners describe instances where the adaptive cruise control fails to maintain a safe following distance, especially around curves, leading to near-collision situations. Another reported issue involves the Highway Drive Assist mode, where the system can disengage without warning, leaving drivers unaware that they need to regain control. These issues pose potential safety risks, especially at highway speeds. Some complaints also note problems with the instrument cluster, which intermittently fails to display critical information like speed, further complicating safe operation. These problems have been reported within the first year of ownership, but specific mileage details are not consistently provided.

Owners report several issues with seat belts in the 2024 KIA EV9. Complaints frequently mention seatbelts in the third row and the middle seat of the second row failing to retract or becoming jammed, with one owner noting the problem occurred soon after purchase. A recurring issue involves a malfunctioning rear seatbelt indicator that inaccurately signals a fastened seatbelt when unoccupied, which persists despite multiple repair attempts. In one incident, during a crash, the front and rear passenger seatbelts reportedly did not lock, resulting in injuries. These issues are reported at various times after purchase, with some owners experiencing difficulties with manufacturer support in addressing these problems.

Owners report issues with the 2024 KIA EV9's fuel/propulsion system, primarily involving battery charging and range problems. Complaints frequently mention defective battery cells leading to charging failures, with some vehicles unable to charge beyond 65% or experiencing drastically reduced range from over 250 miles to as low as 60 miles on a full charge. These issues often occur in vehicles with mileage around 5,800 miles. Multiple owners describe a lack of warning lights or alerts accompanying these problems, and some express concerns about potential safety risks, such as unexpected power loss or vehicle shutdowns. Additionally, following a recall, one owner notes a malfunction in the remote vehicle movement feature, which fails to stop automatically, posing a potential safety risk.

Owners report issues with the 2024 KIA EV9's service brakes, including instances where the brake pedal chatters and warning lights illuminate, resulting in reduced brake pressure and sluggish vehicle performance. These symptoms sometimes resolve after the vehicle is turned off and restarted. Another issue involves the parking brake failing to release automatically, requiring manual intervention. Complaints are noted at mileage around 800 to nearly 4,000 miles. While no crashes are reported, the loss of brake function and uncontrolled vehicle movement raise safety concerns, particularly in scenarios where the vehicle could roll unexpectedly.

Owners of the 2024 KIA EV9 frequently report issues with the vehicle's forward collision avoidance and associated ADAS features. Common symptoms include the disengagement of cruise control, lane management, and automatic braking systems, often accompanied by numerous dashboard warnings. These issues typically occur at speeds over 55 mph, particularly during or near highway curves, and some owners note repeated occurrences at specific road locations. One owner mentions that these problems have persisted over multiple service visits without resolution. Another owner highlights the lack of audio warnings when lane-keeping assistance disengages, leading to potential safety concerns, especially on wider lanes or curves. No specific mileage patterns are noted, but the recurrence and persistence of these issues suggest they may affect multiple vehicles.
