Multiple instances of my 2024 Hyundai Tucson Hybrid with the Smart Cruse Control "on" swiftly moving up on the car ahead on the highway then suddenly applying the brakes creating a collision risk from cars behind me. Speed would suddenly drop from about 70 to about 40 without warning. A second problem occurs when either this system or the Forward Safety System over reacts to a car in the next lane and suddenly applies the brakes in the same way. I previously brought the car to Jenkins Hyundai of Leesburg, fl because of similar problems several months earlier and they said it checked out OK and that they were unaware of a problem yet AI reports multiple incidents were reported and there is a potential class action suit ([XXX] vs Hyundai) under consideration. In my opinion, this is a very dangerous problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2024 hyundai tucson is phantom braking. This is a know problem and there is a recall and fix for the 2025 and 2026s but not the 2024s, even though it is occurring in the 2024s. This means the car suddenly and unprompted full-force brakes at highway speeds. We almost got rear-ended on I-25 in Colorado. This has happened many times and it is dangerous. Thankfully we have avoided an accident, but it is documented to have caused accidents for other Tucson owners.

Suspension
Filed Oct 23, 2026
At first oil change in 2025, reported to dealer loud rear noise (boom) followed by poor bouncy driving afterward that continued. Told they couldn’t get the boom sound to reoccur on test drive. (It had only occurred once for me followed by car’s ride feeling looser and more bouncy after that. No repairs made. On third oil change (approx 25,000 miles) I was informed shocks had totally failed and needed replacing and that this premature failure of the shock absorbers was “common” on Tuscons and other Hyundai models. Other models recalled, but not 2024 Tuscon’s yet. Warranty covered it. But was warned some of these models needed shocks replaced every 20,000 miles of even sooner. After repair, the car’s suspension was more stable, less bounce and sway while driving. A few thousand miles later, heard another “boom” while driving after which the suspension felt bouncy and swayed more. Brought back and again told they couldn’t not the boom sound to reoccur during test drive. Told shocks were ok. At 30,000+ miles, guests riding with me agree car’s ride seems bad, doesn’t hold the road well on turns and every little bump is felt and the car takes several moments to rebound after a bump and stop bouncing. I fear there is a safety issue with the shocks or other parts of my car’s suspension system. On-line reviews/reports and chat rooms confirm other owners of this model of car are experiencing similar issues. Please investigate whether a recall is needed.

I am filing a safety complaint regarding my 2024 Hyundai Tucson N Line Hybrid (VIN: [XXX]), purchased as a Hyundai Certified Pre-Owned vehicle from Balise Hyundai in XXX. Since purchasing the vehicle, I have experienced a persistent grinding noise that continued despite multiple dealership visits. Initially, I was told a pebble lodged in the rotor was causing the noise. Further evaluation by the dealership’s General Manager and Service Manager led to additional investigation and proposed repairs. On XXX, I was informed that a factory-welded nut was not attached to anything on the vehicle’s floor support structure. The dealership advised that the vehicle was unsafe to drive and had to be moved to the collision department for further assessment. On XXX, the Service Manager informed me that the proposed repair would require removal and replacement of the entire floor pan. This raises serious concerns about a potential manufacturing or assembly defect in a structural component of the vehicle. My primary safety concerns include: An apparent factory-related defect involving an unattached welded nut on the floor support structure. The dealership’s determination that the vehicle was unsafe to drive. Potential risks to structural integrity, crashworthiness, and occupant protection. The need for extensive structural repairs on a relatively new vehicle. Whether similar defects may exist in other vehicles of the same make and model. The persistent grinding noise and multiple service visits preceded the discovery of this structural issue. I am concerned that this defect may have safety implications beyond my individual vehicle. I respectfully request that NHTSA investigate this condition, determine its potential safety implications, and assess whether similar manufacturing or assembly defects may affect other vehicles. Dealership service records and documentation of the diagnosis are available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On Monday, 09/14/2026 at approximately 10:15am Mountain Time Utah State Route 36, North-bound. -- I was driving straight, approximately 60mph on dry road on a sunny day. There was no other traffic on the road either ahead, alongside, or behind me and no oncomming traffic. The Automatic Emergency Braking engaged, the emergency braking indicator flashed on the dashboard and the car slowed way down and then it just stopped engaging and the car rolled freely. I believe that the forward collision warning also sounded. NOTE-- this is not the first time this has happened to me. It has happened at least 3 to 4 times over the past two years since we leased the vehicle. I have asked the dealership service department to look at it, but they state that they can find no indication of any problem and that they have been unable to reproduce the event.
