2023 Hyundai Tucson UNKNOWN OR OTHER

Horn did not work. At about 67,000 miles on my vehicle my horn stopped working. I took it to the dealership to be replaced and paid for it. Then again at about 100,000 miles it stopped working. I took it back to the dealership and asked if there’s been any recalls they stated not at this time but there’s been a lot of people complaining about their horns and they told me to save my receipt receipts because I might be able to get reimbursed later. On two different occasions. I’ve been driving and had a car changing lanes into my lane and when I went to honk the horn to alert them, it didn’t work. Now I’m also concerned that I’ve got the same horn put on my vehicle for a third time and that I’m going to have to go back in and pay for a third one. I did reach out to Hyundai USA first and ask them to make this right but they stated they do not have an extended warranty for the 2023 vehicles even though they do have bills for 2020 through 2022. I can get copies of the receipts if they’re needed

Sun roof on Tucson 2023 shattered while car was being driven. When the roof shattered there was a loud sound (like a bomb going off) in the car and then the sound of glass breaking. The vehicle is available for inspection. There were not any warnings or messages before the failure. Safety was at risk for the passengers and any vehicles that were following. The loud sound caused the driver to swerve and could have caused an accident if another vehicle was on either side of the car. The vehicle was taken to a dealership and shown the damage and the service advisor stated he never heard of a problem. I have contacted Hyundai and they said it might take 6 to 8 weeks before an inspection could be made. There are many messages on the web from people with the same issues. Hyundai did a recall for this same issue for earlier production dates.

Dear Commissioner and DMV Officials: I am writing to formally address a serious financial and safety concern affecting vehicle owners in Connecticut. As a driver with over 50 years of experience—32 of those in CT—I have never experienced rodent damage to any vehicle until purchasing my 2023 Hyundai Tucson. Since acquiring this vehicle, I have suffered thousands of dollars in damage from rodents chewing through the wiring and wire housing. Multiple mechanics have confirmed this is due to manufacturers switching to soy-based and plant-derived biodegradable materials in wiring insulation. These materials are effectively edible, attracting rodents year-round—not just in cold months. This is not owner negligence. The root cause is a material deficiency in the vehicle's manufacturing. Consumers should not bear the financial burden of a known design choice made by the automaker. Repairs are costly, often excluded from warranties, and frequently not covered by insurance. I respectfully request the Department: Investigate the scope of rodent damage complaints linked to bio-based wiring in newer vehicles. Coordinate with NHTSA to evaluate whether this constitutes a safety defect warranting a recall. Advocate for regulatory standards requiring rodent-resistant wiring materials. Urge manufacturers like Hyundai to offer warranty coverage, reimbursement, or retrofits for affected vehicles. I am prepared to provide documentation of my repair expenses upon request. Thank you for your attention to this matter. Respectfully submitted, [XXX] cc: NHTSA, CT Attorney General, CT Consumer Protection, Hyundai Consumer Affairs INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Two times while stopped or idling behind a car in traffic, my Hyundai Tucson 2023 has started accelerating on its own with the RPM increasing to nearly 8000 and lurching forward before I was able to apply brakes. Stop the car and restart. I have seen this described on other car message boards and hope the NHTSA will take this seriously. The dealership is not being helpful and claims they cannot reproduce it and it has not caused any onboard diagnostic codes.

My 2023 Hyundai Tucson’s windshield has developed excessive pitting, multiple chips, and cracks despite only normal highway driving. I do not drive on gravel or dirt roads, yet the glass shows abnormal wear far beyond what would be expected for a vehicle this new. One of the larger chips was repaired by Safelite, and during the repair the windshield cracked further, suggesting the glass is unusually weak or defective. Visibility has become noticeably compromised due to the fine pitting across the entire windshield. Based on the number of similar complaints from other Tucson owners, this appears to be a recurring safety issue with Hyundai windshields.

the blue tooth handsfree phone button does not work i took it into service and told them I was told the update to fix it wont come out until December so in the meantime for 3 months I have to not be able to work or talk in the car because it is unsafe to use the phone without it being handsfree

After using horn on rainy highway driving it stopped working completely. Called dealer with issue and scheduled appointment. After two day they said it is a know issue and horns will take 2-3 business days to order. Took 5. Getting horns replaced today but told by service tech that this is a known safety issue to Hyundai. Horns are a basic piece of equipment. Should be recalled and better designed.

UNKNOWN - was parking in a spot and car accelerated uncommanded, stepped on the brakes and car did not stop. It stopped with parking sign cement post.

Upon closing the driver’s side door, the panoramic sunroof exploded. The car is currently at the dealership where it was purchased. It is available for inspection. Safety……Any occupants within the vehicle would have been exposed to the shards of glass if the sunshade was open! The dealer stated that Hyundai has approved the replacement of the exploded sunroof glass and the cleaning of the glass remnants inside the car. The was no warning or symptoms prior to this incident. We requested a loaner vehicle but as of today we have not received one. Completion date stated 1 week..order and installation. The rounded upwards photo of the sunroof glass, the stress fractures at the front and rear of the glass as well as the inward bending of the front sunroof corners gives every indication of an upward movement of the glass from within the car. It was not damaged by any objects external to the vehicle. There are many similar incidents cited on the internet

Horn stopped working even the fuse is fine still horn not working . Not panic alarm sound either.

Failure to accelerate. While entering Route 95 from on ramp traveling at about 40 miles the car failed to accelerate. Gas pedal revved engine but failed to accelerate and slowed. Safety of myself and others in grave risk as I was trying to merge into traffic that was traveling at 65 miles per hour. I contacted dealer and was told appointment was not available for weeks and they never heard of the problem. I will bring auto into dealership and leave it with them as it is clearly unsafe to drive. No warning light on dash or engine light problem was present.

The trim on the driver's side rear door flew off while traveling at approximately 65 miles per hour. Luckly no one was behind me. I was able to retrieve the trim piece from the highway and it was determined to have been placed improperly on the car. The trim was not able to be replaced due to damage when it was run over by several vehicles. The warranty says it's covered but the trim has been on back order for a month.

I was driving on I95 and all of sudden the truck started sputtering and shut off. I turned off and back on , it would not go. Then the engine light came on. There was also smoke coming from the tail pipe when I tried again to start it. Back in December 2022, I was driving and the truck cut off and would not start at all. It was diagnosed as the Ignition coil being the problem. This horrible, both times could have been worse because of it cutting off while driving.

Trunk door opens by itself. This has happened after exiting vehicle at least 3 times when vehicle is parked. Has not happened while moving
