The vehicle is experiencing an immediate and severe safety hazard involving the sudden, simultaneous failure of multiple Advanced Driver Assistance Systems (ADAS). Specifically, both the front and side collision warning systems repeatedly trigger false visual and audible alerts when there are no physical obstacles, surrounding traffic, or adverse weather conditions present. Most critically, these false sensor alarms frequently result in severe "phantom braking" incidents. While traveling at normal cruising speeds, the Automatic Emergency Braking (AEB) system unexpectedly engages and aggressively applies the brakes without warning or cause. This unprovoked deceleration creates a critical hazard, drastically increasing the risk of a rear-end collision from trailing vehicles. A temporary mitigation requires manually changing the driver assistance settings from "Active Assist" to "Warning Only" every time the vehicle is turned on, as the system defaults back to active braking upon restart. Cleaning the windshield camera and the front radar plate does not resolve the issue, pointing to a deeper systemic electronic, hardware, or software network failure within the vehicle's safety management modules. The manufacturer needs to investigate this multi-zone sensor malfunction and the resulting unexpected automated braking actions.

2022 Hyundai Sonata, approximately 34756 miles, purchased used. On XXX, during heavy rain, the under-engine splash shield/water shield detached from the vehicle with no impact, road debris contact, or collision; it was found detached in normal wet-weather conditions. The engine under-cover was also bent. I presented the vehicle to WEST PALM BEACH HYUNDAI ([XXX]) for warranty repair. The claim was denied with a handwritten note stating the part was "damaged by outside influence." The dealership's multi-point inspection video states the condition is "not covered under warranty due to external factors," but no impact damage or technician findings of an external strike were provided to me. I am aware of a prior NHTSA complaint for a 2022 Hyundai Sonata in which a splash shield ripped without impact, suggesting a possible pattern of premature attachment/component failure rather than external damage. I am repairing the vehicle out of pocket. No crash, injury, or fire occurred. Requesting investigation of premature detachment of the splash shield and its attachment hardware on the 2022 Hyundai Sonata.

The fuel tank assembly became pressurized with compressed air due top worn purge control system check valve. This caused the tank to deform and the deformation of the tank led to the fuel pump being pushed out and the back seat of the car was completely unattached and no longer secured. There was a strong presence of gas smell in the car as well. The check engine light came on and the car began to drive poorly. It was taken directly to a Hyundai dealership where it remains as of today. This could have resulted in the car catching on fire and potentially killing everyone in the car. My [XXX] daughter and 2 friends was driving the car from Louisiana to Mississippi when this occurred. The dealership in MS told her she needed to call and find someone to come and get her because the car was not safe to drive. My daughter was stranded in another state and had a college friend come and get them since I did not have a car and I was in Louisiana. After several hours her friend was able to pick them up which she remained stranded in MS for an additional 4 days. I had to get a friend to meet them halfway and bring her home because the dealership said there was nothing they could do to assist with transportation. This occurred on [XXX]. My car remains at this dealership in MS with only the testing to say the gas tank test failed and the car could not be driven. I was told Hyundai would offer a buyback on my vehicle because the repair was costly and time consuming. I have not been reimbursed for my transportation expenses through Uber as of today. I was told I could rent a car and they would reimburse my expense after I submitted a receipt and waited several weeks to process and then at least 2 weeks for the payment to clear. Either way I have received nothing. There was not any warning and the dash lights and poor engine running all happened at once. She drove straight to the dealership on [XXX]. We have not been treated fairly with this situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S

The passenger compartment climate control blower motor circuit suffered a severe thermal overload. The terminal overheated, shorted out, and physically melted the primary engine wiring harness (Part #91400-L0051) inside the main fuse block connector housing while the vehicle was operating. This caused an immediate smoke/fire hazard in the cabin and a total loss of window defogging and climate control functionality. This structural breakdown is directly tied to the electrical failures documented in Hyundai TSB #WTY037 / 25-EE-002H.

RECALL REMEDY FAILURE AND MANUFACTURER COERCION My Certified Pre-Owned 2022 Hyundai Sonata Limited has been held completely out of service at an authorized Hyundai facility since June 2, 2026, due to severe fuel tank expansion under active NHTSA Safety Recall 25V-796 (Hyundai Campaign 286).The dealership confirmed that the defective expanding plastic fuel tank ballooned with enough force to structurally warp and buckle the unibody center floor pan and frame rails. Rather than providing a safe, timely remedy under federal recall guidelines, Hyundai Corporate and the dealership are attempting to coerce me into an unfair, non-statutory "voluntary trade-in" that simply pays off my remaining loan balance ($22,000) while completely wiping out the $9,000 in cash equity ($3,000 down payment and $6,000 in monthly payments) I have invested into the car. Upon rejecting this predatory trade-in offer, the manufacturer immediately threatened an additional 6 to 8-week delay to attempt a massive structural frame and unibody pull, which would bring the total out-of-service time to over 90 to 110 cumulative days. Furthermore, the dealership is actively withholding the internal diagnostic write-ups and structural alignment prints from me. I am requesting that the NHTSA investigate this recall remedy failure. Hyundai is using extreme delays (90+ days) and structural frame threats to force consumers to abandon their financial equity rather than issuing lawful, purchase-price repurchases for vehicles deemed structurally unsafe due to a manufacturing defect. I can't provide any documents as they have refused being able to provide me with any. Was told I would be emailed a copy from the dealership several times and they never end up sending over any information.

Some Hyundai vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

Some vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin outlines the combustion chamber cleaning procedure for vehicles diagnosed with this condition. All internal combustion engines consume some engine oil during normal operation, depending on driving conditions and mileage, and this procedure should only be performed when deemed necessary based on inspection and diagnosis of the vehicle as outlined in TSB 26-EM-015H, Engine Oil Consumption – Inspection & Repair Guidelines, or the latest revision.

Certain vehicles equipped with internal combustion engines may exhibit higher-than-expected engine oil consumption. This bulletin provides the inspection and repair procedures for vehicles exhibiting this condition. All internal combustion engines consume engine oil as part of normal engine operation. Oil consumption rates may vary based on mileage, operating conditions, driving habits, and maintenance history. Hyundai recommends following the prescribed maintenance schedule and periodically checking the engine oil level using the dipstick to maintain proper engine oil level.

This bulletin provides information related to a Transmission Control Unit (TCU) software update for some vehicles equipped with an 8-speed wet dual clutch transmission (8WDCT). The software update revises the touch point learning variation, improving drivability and judder symptoms. Some 8WDCTs (indicated by a new part number) received an updated clutch spring. The correct TCU software update must be matched with the correct corresponding 8WDCT hardware, otherwise, drivability concerns may occur. This service procedure should be performed prior to any 8WDCT replacements done for drivability/judder concerns.

Some vehicles may exhibit difficulty starting in cold weather. This bulletin provides the procedure to perform an inspection on the starter magnetic switch for potential freezing and, if necessary, replace the starter magnetic switch (solenoid) assembly.
