2024 Hyundai Tucson Electrical Problems

Your vehicle has an active safety recall that hasn't been fixed for 4 months, affecting the electrical system and service brakes. Both the dealership and manufacturer have indicated they don't consider it urgent, but you're concerned about the safety risk. Resolving this will likely require the dealership to apply the manufacturer's recall repair once a fix is available.

Your 2024 Tucson is subject to Hyundai Recall #290 due to a fire hazard involving the trailer wiring harness accessory module. Hyundai has not yet provided an official fix, and the company is refusing to reimburse you for the approximately $200 cost to have a dealership remove the wiring harness, even though you don't use the trailer module. You're concerned that the wiring could ignite if exposed to moisture, creating a safety risk while you wait for Hyundai to issue a remedy. The fix would likely involve removing or disabling the trailer wiring harness and potentially reimbursing owners for out-of-pocket removal costs once an official remedy is established.

Your 2024 Tucson is subject to Hyundai Safety Recall #290 for a defect in the tow hitch wiring harness control module that can allow water inside. This defect may cause your brake lights to stop working or, in rare cases, create an electrical short that could lead to overheating or fire. You received the official recall notice in February 2026, but when you contacted Hyundai three times, they told you there is no repair solution, parts, or timeline available yet. Hyundai advised you to keep driving the vehicle despite this known fire and brake light safety risk, with no interim safety measures or inspections offered.

While slowly pulling into a parking spot at about 10 feet from the curb, your car suddenly accelerated much faster than expected, causing it to jump the curb and hit a tree. Before this incident, your car had been experiencing progressive delays in acceleration response—sometimes taking a second or two after pressing the pedal before the car would respond. The dealer was unable or unwilling to retrieve the event data recorder information to determine what caused the sudden acceleration.

After taking your car to the dealership to replace an amplifier, your front and backup cameras stopped working properly. The dealership has visited twice but hasn't been able to identify the root cause of the problem. Since you work in a school environment where these cameras are critical for safety, this is a significant concern that needs to be resolved. The fix will likely involve diagnosing and repairing the electrical connection or wiring between the camera system and the vehicle's main electrical/audio system.

Your car is producing random warning beeps while you're driving, but nothing shows up on your dashboard or screen to explain what's wrong. This unexpected noise is distracting you from the road as you try to figure out what it means, creating a safety concern. The dealership has inspected the vehicle and seen the issue happen, but they haven't been able to identify what's causing it or fix it.

The contact owns a 2024 Hyundai Tucson. The contact stated while driving approximately 60 MPH, the vehicle stalled. The contact stated that before the vehicle stalled, there were several unknown warning lights illuminated before the instrument cluster went black. The contact pulled over and shifted to park(P) and was able to restart the vehicle after several attempts. The contact stated that the failure had occurred intermittently and at various speeds. The vehicle also occurred while stopped at a traffic signal. The contact had taken the vehicle to a local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 18,000.

The contact owns a 2024 Hyundai Tucson. The contact stated that while the vehicle was parked, the horn was inoperable. The vehicle was taken to the dealer where it was diagnosed that the horn needed to be replaced. The vehicle was repaired. The contact related the failure to TSB: 23-BE-008H (Horn Assembly); however, the VIN was not included in the TSB. The manufacturer was notified of the failure and a case was opened. The failure mileage was 68,412.

Both horns failed in less than 15k miles. Any time spent on the internet shows this is a known issue. Reporting as a safety problem as you will not know they are gone until you need them to warn another car or person and you have no sound. Luckily I was not speeding and paying attention but the kid who rode a bike in front of me when my horns failed - wondered right out. I stopped just short of them. Only resulting in them falling over when they finally saw me and freaked out/fell over. Horns are located extremely close to the ground and can only be accessed if you remove the entire front bumper and side trim. So this isn't an easy fix for most people when/if they go out.

A service bulletin for windshields leaking into 2024 Santa Cruz and Tucson vehicles was issued on 11/02/23 from Hyundai, causing passenger side flooding.The length of time these models were exposed to or held water could pose these safety risks: 1 Corrosion of various mechanical and electrical parts from water entry for months that could cause safety risks at a later time. Ex. Certain Hyundai vehicles were recalled in 2006-2015 for fires originating from the ABS system due to liquid leaks and corrosion caused by failing seals and leaking water. The electric systems could short out, spark, and cause a fire, posing a risk even when the car was not in operation. 2 The possibility of the presence of invisible mold spores that grow quickly inside a closed car environment is a serious health risk for those who have a high allergy to mold, allergic asthma, COPD or other lung problems. 3 Some vehicles also experienced water entry from a firewall separation from the windshield. If the firewall is part of the unibody construction and protection for components and passengers, this is concerning. 4 Inadequate or improper repair instructions cause new owner concerns regarding the integrity of their vehicle. A. Hyundai only authorized dealers to “...insert sealant in the area that has been improperly sealed.” An auto water leak tech reported such windshield leaks require a glass company for repairs. The dealer reported around eight other vehicles have experienced the leakage at their shop. I know of no inspections by Hyundai or other service techs but is available. I did not know my car had water in the passenger side for the two months I had it. These models have been exposed to water entry from their manufacture date from this defect that somehow slipped through inspection and quality control. A Hyundai forum reported that some models experienced windshield leaks back in 2020. I am very concerned that this continues to be a cost cutting practice passed on to consumers.

the entire computer system shorted out throughout the entire car. It did not let me select above all of what it affected. The entire car malfunction due to the dealer not doing predelivery inspection. They have the vehicle and have not given me a written explanation or reports as to what happened to cause this. This vehicle was defective and dangerous and should not have been sold.
