2024 Hyundai Tucson

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.

On October 2026, 2026, when driving under normal conditions and making a routine turn signal (driving slowly and signaling while coming to a stop sign), the turn signal lever fell off of the steering column into my hand. I immediately drove to my local dealership and was told no one could assist me that day, so I scheduled the next available appointment which was the following morning. The broken turn signal lever was repaired by the dealership and seems to be working well after repair. I purchased this vehicle, a certified pre-owned 2024 Hyundai Tucson hybrid, 6 months ago. I have driven fewer than 8,000 miles and the car has less than 20,000 miles total. The dealership refused to cover this repair under my vehicle's existing, unexpired warranty. My impression from the dealership service team as well as my interaction with Hyundai customer care was that they refused to acknowledge the possibility that this was an equipment defect, and I did not receive any reassuring guarantee that this would be investigated as a defect that could endanger other drivers. A basic internet search on my part revealed a number of past user complaints on forums such as Reddit and Facebook about cracked or malfunctioning turn signals on Hyundai vehicles. I am sharing my experience and making this report so that this example is taken seriously and investigated as a safety concern.

The vehicle suffers from a severe, unresolved manufacturing safety defect causing an intermittent loss of propulsion during highway operation. On multiple occasions under highway acceleration, the engine RPMs spike high but the vehicle completely fails to respond or accelerate, causing a dangerous power drop down to 65 MPH in active traffic lanes. To regain throttle response, the driver is forced to execute an emergency lane merge to the highway shoulder, turn the ignition completely off to clear the system, and restart the motor. The vehicle simultaneously exhibits an progressive powertrain defect path, including severe drivetrain binding where shifting into reverse gear triggers a violent physical thud and blocks the rear axle from backward movement until excessive throttle is applied. The vehicle also has a documented history of chronic Cylinder 1 engine misfires paired with an active loss of interior cabin heat at an engine idle, which indicates an internal combustion cylinder block or head gasket breach. The authorized franchise dealership has continuously failed to execute a physical component teardown to resolve the underlying structural root causes. Instead, service drive personnel cleared stored error codes on a stationary vehicle while falsifying vehicle road-test odometer metrics on the final invoice. This vehicle is actively utilized for commercial child transportation and nanny services, and the manufacturer has had formal notice of these recurring, un-remedied safety defects under active corporate case files well within full warranty windows. An independent federal safety review into these drivetrain tracking parameters is requested.

The system is sold as a mandatory dealer installed option by Weisner Hyundai as a system that flashes lights at vehicles before they rear end you. In reality, it just pulses the center brake light 4 times every single time you brake which to my understanding is not allowed federally and makes the vehicle inoperable and just confuses other drivers.

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 NHTSA'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 NHTSA's evaluation; I do not yet know the underlying technical cause. My primary concern in filing this report is vehicle safety. I request that NHTSA 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

NHTSA VEHICLE SAFETY COMPLAINT Vehicle Information: * Year: 2024 * Make: Hyundai * Model: Tucson * VIN: [XXX] * Mileage: Approximately 65,000 * Dealership: Hyundai of [XXX] Complaint Description: I am filing this formal safety complaint regarding my 2024 Hyundai Tucson, which is experiencing recurring water intrusion and electrical malfunctions. Every time it rains, water enters the interior of my vehicle, causing flooding. This is not an isolated incident. The flooding occurs repeatedly during rainfall, and I am extremely concerned that there may be an underlying manufacturing, assembly, sealing, or drainage defect. In addition to the flooding, my vehicle’s electronic systems have begun malfunctioning. My radio operates on its own without my input, my touchscreen becomes unresponsive, and the buttons do not function when needed. I am concerned that water may be reaching electrical components and contributing to these malfunctions, although the exact cause has not been determined. I have not been involved in an accident or caused any known damage to the vehicle that would explain the recurring water intrusion. I reported my concerns to Hyundai of Orange Park in [XXX]. However, I was informed that because my vehicle is outside its warranty coverage, I would be responsible for the diagnostic and repair expenses. When I escalated my concerns to a Hyundai supervisor, I was presented with two options: pay thousands of dollars to have the vehicle disassembled to investigate the problem or purchase another vehicle. My concerns about the possible safety implications of the flooding and electrical malfunctions remain unresolved. I am particularly worried about moisture-related electrical failures, corrosion, and the possibility that additional vehicle systems could malfunction. I am concerned about the safety of myself, my passengers, and others on the road. This vehicle is a 2024 model with approximately 6 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was notified about a recall for the tow hitch wiring harness. I took it to the dealer to have it repaired. Instead of repairing it, they just removed the wiring harness from the vehicle. When I asked them when the actual repair would be completed they said they had no idea. The service manager at the Hyundai dealership told me that some of his customers were mad about not having a safe and working tow hitch package that they had paid for, after they removed the wiring harness, that they were taking their cars to U-Haul dealers to have tow hitch wiring harnesses installed. He also told me to call the Hyundai customer service hotline which I did. The hotline told me that they could not even tell me if they were even working on a permanent repair for my car. The recall for my car now states "COMPLETED", which is totally wrong. They simply removed the wiring harness, without doing any actual repairs, leaving the tow system completely inoperable and VERY unsafe to use. I am now left with a car that is now unsafe when towing a trailer due to it no longer having a wiring harness installed for it, so I now have no trailer lights.
