On July 17, I took my vehicle to Hyundai of Venice due to a safety recall of the automated emergency brake, the dealership told me that they had fixed the recall. On October 10 when I returned for service, I again notified them that the safety features such as the automated emergency brake and the Forward collision warning were not working. They ignored me again. Then on October 21, 2026, I was driving my mother to run an errand before her doctors appointment as I was pulling into a parking spot going no more than 3 mph. The safety features were still not working and I scratched the vehicle on the left of me which was empty. I then stopped the car, got out and took pictures of the license plate and of the scratch, and then looked at my front bumper and saw that I was also scratched, my mother, and I went into the supermarket to speak to the manager and attempt to call for the police, but then my mother noticed their brake lights were on and people were in the car so we hurried out to notify them that we had scratched their car by accident, I gave my insurance information and my mother gave her telephone number and after her doctors appointment, I contacted my insurance company to notify them of the issue. My concern is that I notified Hyundai of Venice twice about this issue, but due to my autism, I feel that they ignored me, and this small accident could have been avoided if they had checked that my safety features on this new vehicle were all fully functional.

I am submitting this complaint to report a potential safety concern involving the Forward Safety (Collision-Avoidance) System and Smart Cruise Control System in my Hyundai vehicle. I am concerned that these warnings may indicate a problem with safety-related driver-assistance systems, and I want to bring this issue to the federal safety agency's attention so it can be evaluated for potential risks to other vehicle owners. Vehicle and diagnostic information as - Make: Hyundai - Model: Hyundai Tucson SEL FWD - Model year: 2024 - Purchase date: March 2024 - Odometer reading: 24,359 miles - Diagnostic Trouble Code (DTC): C174181 - System identified in Bluelink: Chassis - Date the code originated: October 13, 2026 Description of the problem My vehicle's dashboard displayed the following warning messages: - Check Forward Safety System (Collision-Avoidance System) - Check Smart Cruise Control System On my Hyundai Bluelink account also displayed an “Attention Needed” notification identifying one chassis diagnostic trouble code, C174181, originating on October 13, 2026. These warnings concern systems intended to assist with collision avoidance and vehicle following distance. I am concerned that their malfunction or unavailability could reduce the vehicle's driver-assistance capabilities and potentially create a safety risk while driving. I am reporting the symptoms and diagnostic code for the federal safety agency's evaluation; I do not yet know the underlying technical cause. My primary concern in filing this report is vehicle safety. I request that the federal safety agency record and evaluate this complaint and determine whether similar reports involving Hyundai vehicles indicate a potential safety-related defect that warrants further investigation. I am submitting this information to help identify any possible recurring problem that could affect other drivers, passengers, and road users. I can provide screenshots from Bluelink, warning-message photographs, repair orders and additional diagnostic information if needed. Thanks

Approximately one week after having my oil changed at a Hyundai dealership, I began experiencing intermittent collision safety alerts and multiple dashboard warning lights. On three separate occasions when I started the vehicle, warnings appeared for the forward and rear collision systems, along with multiple other sensor warnings and engine warning lights. During one incident while driving in traffic, the forward collision warning activated and the vehicle abruptly applied the brakes. I was nearly rear-ended as a result. I have taken the vehicle back to the dealership on two separate occasions. The dealership reported replacing a sensor, but the warning lights and collision system issues have continued to occur intermittently. I am concerned that the vehicle may unexpectedly apply the brakes again, creating a risk of a collision.
