2024 HYUNDAI TUCSON Complaints

Sudden loss of speed for no reason. was traveling at 35 mph when vehicle suddenly dropped to 22 mph. Stepped on gas with no response. I know the 22 mph because it showed up on warning illuminator. Car behind me almost hit me because he had no indication (prior warning). Turned off at closest exit, turned vehicle off then on restart things were normal. Took to dealer and they found nothing in computer code or mechanical to explain why this happened. Am an older women afraid what will happen if repeats on highway going 70+ mph. Please made Hyundia find and fix.

Horns failing after being replaced by Hyundai. A kid was running and heading on a path in front of the SUV. Pushed the horn and another failure. Luckily the brakes work - the kid didn't stop. First attempt to fix: 14,612 miles - current miles at 2nd failure 17463.

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.

While sitting in stopped traffic on the interstate in the dark in the rain on 11/25/2024 my car was in drive; my foot was on the brake. Twice the car rolled away despite my attempts to brake or put the car in Park (I shoved the shifter into Park and the car continued to roll). I rolled into the back of a semi because I could not get my vehicle to stop. This had already been noted as a problem with 2024 Tucsons, yet your search engine tells me there are 0 unrepaired recalls for my car. I want to call this out as an unrepaired recall. I have left it with the Hyundai dealer at the moment. They tell me if they cannot make the problem happen for them they won't do anything to fix my car. This is a dangerous situation for me and for anyone with a Tucson that may have the same problem.

Headlights get covered with slush and snow while driving causing you to lose vision of the roadway at night. You are not able to see creating a safety risk to you and others on the road, potentially causing an accident that would cause serious injuries or death. Yes, it can be inspected upon request. Notified our dealer and was advised that this has never been brought to their attention as a problem from any other buyer. During our last vehicle service at our dealership when notifying them of the concern no issues with the vehicle were found. Warning lamp (obstruction) appears while driving. When the warning lamp illuminates, we need to pull over (sometimes not in a safe environment), wipe the slush/snow off of the headlights and proceed traveling. After wiping the headlights off, warning lamp on dashboard returns to normal operations.

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.

Car throttle, AC, Cruise control, car transmission and gears not correct, radio turns off completely and messes up CarPlay. Also no updated radio. Scary car is still new with all of these issues.

While driving in light traffic, speed at 45 mph, my Tucson alerted me with a beep, steering wheel vibrated and a red alert on the dash was present for about 3 seconds then the speed automatically slows down to 15 mph all on its own while my foot is still on the accelerator. This has occurred at a minimum 6 times. I purchased this vehicle brand new and driving it off the lot it had 22 miles on it. I've taken it to a Hyundai dealership, and they can't figure out what it wrong with it. I feel very unsafe and unhappy now of this major safety concern. This has high probability of getting rear ended. I see that this has been occurring with various years of Hyundai and am wondering why there has not been a recall on this issue. I owned a Hyundai prior to this 2024 (Tucson 2011) and it was wonderful. This is highly concerning for me, and I am not confidant driving this vehicle and will more than likely trade it in for another vehicle. Can someone please research this issue with the automatic emergency brake system. This can autonomously go off whether you are in traffic, highway, street or completely zero vehicles or pedestrians around.

Two incidents while driving on the highway. 1. Emergency braking activated on its own. No cars around me. It was a rural area. The red emergency braking activated light showed up and my car braked but resumed driving. This is a new car with less than 4k miles on it. 2. The hands free assist and cruise control were activated. My care swerved to the right abruptly. My hands were on the wheel and I was able to correct this but this is very concerning as my daughter drives this car on mountain roads when she is going to college. I have read online reports when others driving the same make, model and year vehicle.

Forward radar sensor pass side lower grill/bumper area. 1st told a sensor recall but after 3 hrs and then seeing the vehicle in the shop with the entire front bumper clip removed the sensor was out of its driver side socket and 1 side flopping around which may have caused a small dimple from the inside to pop out on the 6x5 cover that is the entire lower rubber/plastic black bumper/grill. Told the vehicle was hit, YET no visible damage to bumpers or painted surface can be found by their 2 dealerships and their 1 body shop, + 2 mangers, and 1 independent collision shop.1 manager drove the vehicle 10/11 and stated after "is operating as it should". Warnings have come on again since then refueling at additional 77 mile and then at 92 miles 10/14. Hartford ins has been notified and pending I hope an inspection. Vehicle purchased 1st March 2024, 1st warning at 5336mies currently at 5421 miles. They triggered the service engine light and stated via onboard computer it was an issue with a lower front driver side radiator something that may have been bumped while taking off the front clip, which they chipped and area and left a bit of gap at the fender connection. Other than the small dimple on the plastic from what I believe the sensor had been bouncing against, there is no damage. A safelight windshield company stated there is a notice/recall on the "auto headlight sensor on dash" but they do not cal them, only the optic sensor top center of windshield. BUT per the manual that top sensor plus lower radar can control the forward crash, cruise setup and auto braking. Need some help since my firm works with all auto/tire mfg and conducts DOT tire testing for USA and worldwide independent firms/gov's.
