Technicians having a hard time recalibrating certain new model Hyundai vehicles aren’t imagining things. The automaker recently recalled hundreds of thousands of cars for overly sensitive advanced driver assistance systems.
Hyundai Motor America issued a voluntary recall on May 18. According to the manufacturer’s report to the National Highway Traffic Safety Administration (NHTSA), the recall affects 421,078 2025 and 2026 Hyundai Santa Cruz, Tuscan, Tuscan Hybrid and Tuscan Plug-In Hybrid vehicles.

report says, meaning they’ll engage when they detect objects in front of the vehicle that aren’t actually close enough to pose a threat and brake suddenly. The FCW systems operate using windshield-mounted cameras.
“Sudden braking may increase the risk of a rear-end crash with closely following vehicles,” the report says.
Hyundai explained to the NHTSA that the camera’s software logic is “conservatively tuned” to speed, operator input and closeness to other vehicles to avoid collisions. In this case, it was a bit too conservatively tuned. The company Mobis manufactured the cameras with potentially faulty software in Korea, according to the report.
Hyundai first learned of the potential defect in January of 2025 after receiving a vehicle owner questionnaire, the automaker says. Hyundai began reviewing data and investigating by June 2025. The automaker involved the camera manufacturer, Mobis, by the fall. According to the report, Hyundai kept the NHTSA’s Office of Defects Investigations (ODI) up to date on the investigation starting Sept. 29.
Hyundai continued testing camera functions through the spring of 2026 at test tracks in California and Korea. After reviewing the data and receiving advice from ODI, the car manufacturer decided to launch the recall on May 11.
“As of the decision date, Hyundai has received 376 reports related to FCA operation,” the company tells NHTSA. “… Of these reports, four indicate crashes in which Hyundai vehicles were rear-ended by closely following vehicles, allegedly resulting in four injuries. There are no confirmed fires or fatalities attributable to this condition in the U.S.”
Hyundai plans to inform owners of a solution to the problem on July 17. According to the report, owners can bring their vehicles to a Hyundai dealership to have the front camera software recalibrated.
“This remedy will be offered at no cost to owners for all affected vehicles, regardless of whether the affected vehicles are still covered under Hyundai’s New Vehicle Limited Warranty,” the report says, adding that Hyundai will reimburse affected vehicle owners who paid out-of-pocket to try and fix the issue.
What about glass shops who had to eat the warranty cost to replace with OEMS and send to dealers on their dimes?
This recall is a good reminder of how critical ADAS technology has become in modern vehicles. While these systems are designed to improve safety, even small issues can have a significant impact on driver confidence and performance. It’s encouraging to see the problem being addressed, and it highlights the importance of ongoing testing, updates, and awareness as vehicle technology continues to evolve.
