2024 Hyundai Sonata Reliability Report

Owners of the 2024 Hyundai Sonata frequently report issues with the vehicle's speedometer accuracy, with multiple complaints indicating that it displays a speed 1-4 mph higher than the actual speed. This discrepancy often worsens after the car is restarted following a short shutdown, such as during a fuel stop. Additionally, there are reports of the Driver Attention Warning (DAW) system being overly sensitive, issuing frequent alerts that some owners find distracting. These issues appear to persist regardless of mileage or time of ownership, and while no direct safety incidents such as crashes or loss of control are reported, the incorrect speed readings and persistent alerts may affect driving focus. Buyers considering this model should be aware of these reported electronic system inconsistencies.

Owners of the 2024 Hyundai Sonata report issues with the vehicle's speedometer accuracy, often noting discrepancies between the speedometer and GPS-based speed readings. Complaints frequently mention that the speedometer can be off by 5 mph or more, particularly after the vehicle has been restarted following a short stop. One owner describes a more severe issue where the car unexpectedly limits speed to 20 mph, necessitating a restart to resolve. These issues are noted at various mileage points, with one complaint specifically mentioning the problem emerging at around 2,000 miles. The potential safety implications include difficulty in maintaining proper speed, which could affect other speed-dependent functions like cruise control, and unexpected speed reductions while driving. Multiple owners indicate that dealerships have been unable to replicate or resolve these problems, and they have not received a satisfactory solution from Hyundai.

Owners report persistent steering issues with the 2024 Hyundai Sonata, specifically involving the Electronic Stability Control (ESC) system. Complaints frequently mention severe and intermittent malfunctions that lead to unpredictable loss of steering control, with symptoms including the vehicle veering unexpectedly and losing precision during turns, often resulting in near-collision incidents. These issues are noted around 17,804 to 20,000 miles, despite previous recall repairs intended to address the problem. Safety implications are significant, as the described defects compromise the vehicle's control and overall safety. Additionally, some owners mention a non-functional parking collision assistance system, which fails to provide audible warnings and further impacts vehicle safety.

Owners report two primary issues with the 2024 Hyundai Sonata's forward collision avoidance system. First, the driver attention warning feature is described as overly sensitive, activating frequently after about 10 minutes of driving and reacting to factors such as wearing sunglasses, without any apparent driver error. This feature cannot be turned off, which some owners find distracting. Second, the forward collision avoidance system unexpectedly engages during left turns, applying automatic emergency braking and bringing the vehicle to a stop, as noted by a complaint at just 60 miles. These issues may pose safety concerns due to their distracting nature and unexpected activation, especially for potential buyers considering this model.

Owners of the 2024 Hyundai Sonata report issues with the vehicle's exterior lighting, specifically the automatic high beams and low-beam headlights. One complaint describes the automatic high beams remaining on continuously when the camera used to control them is obstructed, potentially causing visibility issues for other drivers. Another owner notes inadequate illumination from the low-beam headlights, particularly at night, where they struggle to light road signs and pedestrians effectively. This issue is observed around 3,500 miles, with no apparent solution through headlamp adjustment due to their recessed design. These lighting problems could pose safety risks, especially during nighttime driving.
