2024 HYUNDAI TUCSON Electrical System Problems

My wife was slowly pulling into a parking spot, when at about 10ft from curb the car suddenly accelerated faster than she even thought the car even was capable of (the AWD likely helped). It hopped the curb and hit a tree. She backed it up to the parking spot (it acted normally) and had it towed to dealer. In hindsight, the car had been having a progressive amount and frequency of delay in normal acceleration, sometimes having a pause of up to second or two from pedal input to car response. We asked the dealer to check the EDR (event data recorder). The tech first said he didn't even know what that was, then that he checked with all his fellow techs and they didn't know either, then the story changed to the model not having an EDR. We politely told him which page in the Hyundai manual he...

See attached document for complaint.

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.

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.

Serious Safety Hazard: 2024 Hyundai Tucson Power Steering Failures I have had numerous power steering failures while this driving vehicle. During these incidents, the steering wheel is extremely difficult to turn. This is a serious safety hazard which could lead to a severe accident and loss of life. During each incident occurrence, I noted a red steering wheel with an exclamation point was displayed on the dashboard. The power steering function is restored once I have found a safe location to pull the car off the road and then I reset the car by switching it off completely and then starting it again. My local dealer has not been able to duplicate the problem nor determine the root cause. The dealership has escalated the issue to Hyundai America for technical assistance. I currently have an open case with Hyundai Motor America National Consumer Affairs. I have noted similar power steering...

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....

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.
