Hyundai Tucson Owner Sues Over Ghost Braking Issue

A Hyundai Tucson owner is suing the Korean automaker over repeated ghost braking incidents. Dennis Sperling filed a class action lawsuit in California Federal Court, accusing the 2025 Tucson's Forward Collision-Avoidance Assist system of triggering emergency stops on clear roads.

"The collision avoidance system may turn off, fail to function properly, or function unnecessarily depending on road conditions and environment" — 2025 Hyundai Tucson Owner's Manual

A Safety System That's Causing Problems

Plaintiff Dennis Sperling blames his Tucson's Forward Collision-Avoidance Assist for braking hard with no apparent reason. According to his lawsuit, these ghost braking episodes happened multiple times when the road ahead was completely clear.

The system, designed to prevent collisions by detecting vehicles, pedestrians, and cyclists, allegedly triggers emergency braking even when there are no obstacles. Sperling points out that while no accidents or injuries resulted from these incidents, he's concerned about being rear-ended during these sudden stops.

Defects Acknowledged by Hyundai

The lawsuit cites multiple passages from the 2025 owner's manual where Hyundai lists numerous situations that can disrupt the system. The automaker mentions reflections on wet pavement, extreme temperatures around the front radar, and driving through tunnels or on metal bridges.

More surprisingly, the manual states the system can trigger if "the vehicle ahead has an unusual shape" or "is driving uphill or downhill." For Sperling, these warnings prove that Hyundai knew about the system's defects before releasing it to market.

How Widespread Is This Problem?

The lawsuit seeks class action status to represent all 2025 Tucson owners experiencing the same issue. Multiple online testimonials report similar problems, suggesting the phenomenon could affect numerous drivers.

The system comes standard on the Tucson as part of its driver assistance suite. Beyond vehicle and pedestrian detection, it includes cyclist recognition and intersection assistance. But this technology, designed to improve safety, seems to sometimes have the opposite effect according to complainants.

An Automaker Under Pressure

This case comes as Hyundai faces intense competition in the compact SUV segment. The Tucson remains well-positioned in the American market, but these technical issues could tarnish its reputation for reliability.

The lawsuit accuses the automaker of rushing this technology to market using low-quality sensors and components. It also criticizes the manual's warnings as being downplayed given the risks of unexpected braking at highway speeds.

What Are the Consequences for Owners?

For now, Hyundai hasn't officially commented on this litigation. The automaker will have to respond to the allegations in California court and could be forced to offer technical or financial solutions to affected owners.

In the meantime, 2025 Tucson drivers can disable certain system functions through vehicle settings, though this reduces safety assistance. The manual recommends staying alert and keeping your hands on the wheel at all times.

This case could set a precedent and push other automakers to review their driver assistance system reliability. The lawsuit's outcome will be closely watched by the automotive industry as these technologies become standard across all segments.
