2024 HYUNDAI Sonata

In morning dew/foggy winshield, the systems will disable easily. You get pop ups such as: Inattentive Driving Disabled, Camera Obscured. And forward collision warning disabled, camera obscured. I’ve had many vehicles in the past and the safety systems never disable this easily over slight fog or slight morning dew. Even with a lot of fog on the winshield my other cars are still fine. I also have a 2023 Elantra that has NEVER done this before. It seems to be an issue in Hyundais new driver assistance systems in 2024+ vehicles.

Complaint ID: 11667442 Vehicle: 2024 Hyundai Sonata Mileage: 20,000 (approx.). Update Summary: This update concerns the persistent, severe Electronic Stability Control (ESC) steering malfunction previously reported. Current Status of Issue: The ESC steering defect remains unresolved. The vehicle was taken to an authorized Hyundai dealership on July 15, 2025, for re-diagnosis. The technician reported being unable to find any fault, despite the clear, dangerous, and recurring symptoms of steering control loss and near-collisions. The vehicle is still unsafe to operate due to this unaddressed safety hazard. Manufacturer's Response: During this recent service visit, Hyundai continued to refuse to provide a loaner vehicle for the diagnostic and repair period. This refusal places the driver at extreme risk due to the necessity of driving a vehicle with a known, uncorrected safety defect that has already failed a previous recall repair (performed June 6, 2025, RO 41686321 ). Impact: The vehicle's safety is severely compromised. The persistent ESC defect, combined with the manufacturer's inability to diagnose/repair it and refusal to provide safe alternative transportation, necessitates immediate intervention.

After a dealer-installed software update on my 2024 Hyundai Sonata sel awd, the car began jerking during acceleration and shifting. This happens at low and moderate speeds and creates an unsafe hesitation, especially in traffic. This issue did not exist before the update. I believe the software update affected the transmission or engine control calibration. The dealership has not resolved the issue, and it poses a safety concern. Please investigate whether this is linked to a faulty update affecting other Sonata vehicles.

Vehicle: 2024 Hyundai Sonata. Current Mileage: 17,804 Primary Safety Defect: Electronic Stability Control (ESC) Steering Malfunction The vehicle's ESC system has a severe, intermittent malfunction causing unpredictable loss of steering control. This defect creates an extreme safety hazard. Occurrences include the vehicle veering unexpectedly towards highway medians and losing steering precision during turns and roundabouts, leading to multiple near-collision incidents. The vehicle is currently considered unsafe to operate. Relevant History: This ESC concern was subject to a manufacturer recall. An authorized Hyundai dealership performed the "ESC SOFTWARE LOGIC UPDATE (24-01-065H-1)" on June 6, 2025. Despite this specific recall repair, the severe ESC steering issue has persisted and recurred multiple times since that date, indicating a failure of the repair to permanently resolve the safety defect. Secondary Safety Defect: Inaudible Parking Collision Assistance The vehicle's parking collision assistance system is non-functional. Its audible warnings are inaudible and have never worked as designed since vehicle acquisition. This eliminates a critical safety feature intended to prevent low-speed parking collisions. Finally, The combination of a critical, recurring ESC steering defect, unaddressed by a recall repair, and a continuously inaudible parking collision assistance system, renders this vehicle highly unsafe to drive. Immediate investigation and permanent resolution are required.

Vehicle suddenly accelerated after pulling out of store parking lot at low speed into side street behind vehicle stopped at light (less than a car length in front) while pressing hard on brake. Vehicle lurched forward incrementally during the braking process, but vehicle kept accelerating causing vehicle to hit stopped vehicle numerous times before vehicle engine was finally turned off. Driver of both vehicles could have been seriously hurt. Vehicle was driven home after this incident without incident but has only been driven out of garage and onto and off towing truck. Car has not been inspected except for damage to vehicle and is currently awaiting insurance rep inspection at vehicle repair facility. Once damage is repaired car will be towed to dealership for inspection. Because of the short distance vehicle traveled no warning lamps/messages were noted.
