A lawsuit says Hyundai’s driver-watching cameras can trigger sudden braking in five models

A proposed class action filed in federal court in California alleges that the in-cabin camera Hyundai uses to watch drivers’ attention can misread normal driving and set off alerts that end with the vehicle braking suddenly. The complaint, Ledezma et al. v. Hyundai Motor America et al., names five models: the 2024 to 2026 Santa Fe, the 2025 to 2026 Ioniq 5, the 2025 to 2026 Tucson, the 2025 to 2026 Santa Cruz and the 2026 Palisade. Every claim described here is an allegation by the plaintiffs, and none has been tested in court.

Hyundai Motor America and its Korean parent, Hyundai Motor Company, are the defendants. Neither of the reports reviewed for this article carries a response from the company, so its position on the allegations is not on record here.

What the Complaint Says About the Driver-Monitoring Camera

According to the complaint filed in the U.S. District Court for the Central District of California under case number 2:26-cv-10562 on Sept. 16, the vehicles use a Direct Driver Monitoring System, or DDMS, built around an infrared camera that feeds the Forward Attention Warning feature. The plaintiffs say the camera often reads ordinary, safe driving as distraction when a driver wears sunglasses or glasses, sits at a different height or faces sun glare, and that the result is repeated audible and visual alerts.

The braking allegation is narrower than a quick read suggests, and it depends on cruise control. The plaintiffs allege that when cruise control is active and the alerts go unresolved, the system can shut off cruise control and stop the vehicle. One paragraph of the complaint alleges that the system “brings the vehicle to a complete and sudden stop,” and another describes “a sudden and complete stop in the middle of busy roadways.” The filing also quotes a June 16, 2026 complaint to federal safety regulators in which an owner wrote that the car “decided it was time to slam on the brakes right in the middle of the road.”

The Five Models and the Four Named Plaintiffs

The named plaintiffs are Helen Ledezma and Clifford Leone of California, Daniel Toye of Florida and Jeffrey Weisbrot of New York. They are represented by Paula R. Brown, Christopher R. Rodriguez and Andrew D. Bluth of the firm Singleton Schreiber, LLP. The ClassAction.org summary of the case says the proposed class would cover current and former owners and lessees of the five models who bought or leased them in the United States or its territories.

Autoblog’s report on the suit adds the triggers the complaint lists: heavy makeup or hats, head movement, a seat set too high or too low, sunlight reflecting off sunglasses and rough roads. The plaintiffs say the warnings can arrive, in the words of the filing as summarized by ClassAction.org, every couple of minutes while driving.

Technical Service Bulletin 25-GI-001H and the Fix Hyundai Did Not Offer

Much of the complaint rests on a January 2025 technical service bulletin, numbered 25-GI-001H, that Hyundai sent to authorized service centers. The plaintiffs say it advised dealers to explain the system’s limits and suggested workarounds such as removing or changing eyewear, adjusting the seat or looking at the road. The suit contends that this amounted to no repair and that Hyundai never recalled the vehicles or offered a fix.

The plaintiffs also allege that Hyundai knew of the problem through pre-release testing, customer complaints, warranty data and reports to the National Highway Traffic Safety Administration, and that its safety marketing left the defect out. They also cite the owner’s manual, which according to ClassAction.org lists more than a dozen conditions under which the systems may malfunction. Hyundai’s own owner’s manual page on Forward Attention Warning states that the feature warns the driver when gaze is not on the road, that an in-cabin camera detects the driver’s forward attention, and that the feature can be switched off in the infotainment menu.

Legal Claims and a Separate Hyundai Braking Recall

The plaintiffs assert claims under California’s Unfair Competition Law and Consumers Legal Remedies Act, along with New York and Florida consumer protection statutes, breach of express and implied warranties and unjust enrichment. Their core theory is economic: they say they would not have bought or leased the vehicles, or would have paid less, had the problem been disclosed.

The suit should not be confused with an unrelated Hyundai action from earlier this year. In May 2026 the company recalled 421,078 Tucson, Tucson Hybrid, Tucson Plug-In Hybrid and Santa Cruz vehicles from the 2025 and 2026 model years for a software defect in the front camera that causes unexpected, premature automatic braking. That recall involves the exterior front-view camera and the collision-avoidance calibration, with dealers installing revised software at no cost, and it has no stated link to the driver-monitoring system at the center of the lawsuit.

Because the case was filed on Sept. 16, it is early. No class has been certified, and the filing as described so far gives no damages figure. Owners of the five models who have experienced repeated alerts can report them to NHTSA and to a dealer, and Hyundai has not answered the complaint in the material reviewed, so a defense filing would be the next document to watch. The court record under case number 2:26-cv-10562 is where any ruling on the claims will appear.
