2023 Hyundai Tucson

The contact's son owns a 2023 Hyundai Tucson. The contact stated that while driving at various speeds, various warning lights illuminated, and various messages were displayed on the instrument panel; however, the warning lights disappeared upon restarting the engine. The contact stated that her son was forced to restart the vehicle after the vehicle failed to accelerate from a complete stop on one occasion. The vehicle was taken to the dealer for diagnosis; however, the dealer was unable to diagnose or duplicate the failure. The contact was informed that the vehicle could not be diagnosed unless the warning lights were illuminated. The manufacturer was notified of the failure, and a case was filed. The contact later received a letter from the manufacturer confirming the dealer's information. The vehicle had yet to be repaired. The failure mileage was 21,000.

The contact owns a 2023 Hyundai Tucson. The contact stated that the panoramic sunroof exploded while driving at approximately 40-50 MPH. The rear section of the sunroof glass had shattered into several pieces without impact. The contact closed the shade, and the glass fell inward. There was glass inside the shade and the roof. There were no injuries. There was an abnormally loud sound like a handgun or several balloons popping. The vehicle was previously inspected, and there were no issues found with the sunroof. The vehicle was taken to the local dealer, and the dealer stated that a rock might have caused the failure. The vehicle was not repaired. The dealer referred the contact to the insurance company for assistance. The manufacturer was contacted, and an appointment was scheduled with the local dealer. Additionally, the manufacturer provided a loaner vehicle. The failure mileage was approximately 24,038.

I received a letter in March that there is a problem with The Tow Hitch Harness Accessory which could lead to a fire etc. They said they will come out with a repair. I contacted the Victory Hyundai dealership in Jefferson Ohio where I got the car in April and they said they have a repair but the trailer electrical/ lights will not work. I got a second letter saying they have a solution for repair in May I contacted Classic Hyundai twice to make sure the repair now will allow the lights and brakes on the trailer work. Julie and Jesica there said all would be fixed and the lights and break lights will work. I brought the car there June 5th 2026 and asked again if all would work. Lyna there said no. I left. I called U-hall Streetsboro Ohio and talked to Bill who handles the hitch repairs and they said they could fix totally and have for some dealerships. I called Hyundai customer service Kyre and asked if Hyundai in Streetsboro Ohio can be set up to have it repaired. He said no. He would not document his response to me. I bought this car with their factory installed hitch because I needed one to pull my boat and move other stuff. My lawn tractor broke down and I have to pay $135 to have it towed for repair. I am unable to fish in my boat since I can not pull it. There is a repair that will work at U-haul and they are ignoring it.They want to make the hitch unusable. Uhaul will fix for $250-$350. If they disconnect the hitch electrical and the car is sold the new owner can get into an accident since they would have no lights and break lights, turn signal. This is a high risk for an accident. They intend to eliminate the fire risk and create an accident risk for the trailer now not working. What kind of engineers they have?? They should be contacted about this situation. It has been several months with no solution when one exists. I have had multiple Hyundais and will no longer purchase another vehicle from them. You should communicate with them on this issue.

While driving on a highway shortly after taking delivery of this vehicle as a Certified Pre-Owned purchase from an authorized Hyundai dealership, I experienced sudden and total brake failure. The Electronic Parking Brake (EPB) warning light illuminated and an audible warning chime sounded. The brake pedal did not respond normally. I was unable to slow the vehicle with the brakes and was forced to make an emergency maneuver to exit the highway and come to a safe stop. Upon inspecting the vehicle after stopping, I discovered that the rear left brake caliper had completely detached from its mounting bracket. The caliper was on the ground beneath the rear of the vehicle. Brake fluid had leaked onto the road surface. The vehicle had been in my possession for less than one full drive since purchase. As part of the CPO certification, the selling dealer performed a multi-point inspection and documented installation of new brake pads and certified the brake system as in good working order. The detachment of the caliper is consistent with mounting bolts that were either not reinstalled or not properly torqued following the dealer's brake service during CPO preparation. I have photographic evidence of the detached caliper and brake fluid loss. INJURIES: None, but significant risk to myself and other highway drivers. FIRES: No. MEDICAL ATTENTION: Not required. CONTACT WITH DEALER/MANUFACTURER: Yes — Hyundai corporate complaint filed. I am requesting this complaint be investigated as a potential safety defect related to brake service practices during Hyundai CPO vehicle preparation.

Horn on vehicle consistently goes out. Either goes out entirely or the volume of the horn is below a safe level. This is a known Hyundai issue and Hyundai refuses to acknowledge it on this specific model, but has acknowledged it on different models. I Have had multiple repairs by Hyundai directly, and the horn consistently keeps going out. There are sometimes in dangerous situations where I need to utilize the horn to avoid an accident and warn other drivers of danger, and I am unable to do so, and it causes dangerous driving situations. This is a known defect on multiple Hyundai vehicles in this year, but the Tucson is one of the few vehicles they will not call a voluntary recall on and NHTSA needs to be notified about this and act accordingly as a regulatory body to protect consumers and people on the road.

I received a Recall notice around January 2026 for the trailer hitch wiring harness on my 2023 Hyundai Tucson Hybrid. For 6 months the local dealer told me there was no fix available from Hyundai. I finally received a notice informing me that parts were now available and to bring it in to dealer for repairs. I took the vehicle in for recall repairs on May 27, 2026. Instead of repairing/replacing the wiring harness, Hyundai removed the entire wiring harness making the trailer hitch which I use for my business inoperable legally. When I noticed the wiring harness missing several days later, the dealer said that was Hyundai's "fix" for the recall issue. I contacted Hyundai USA Customer Service who also told me that removing the wiring harness and replacing it with an inexpensive dust cover was the fix. They told me that sometime in the future there will be another recall to have the wiring harness replaced. In the meantime, they have taken my vehicle VIN off the open recall list, since it has been "fixed". Hyundai sold me a vehicle with a trailer hitch and now they have without my permission or prior knowledge disabled it.

I was driving on the freeway no where near an overpass going about 65mph when the front panel on my panaromaic sunroof exploded and glass went everywhere. There is no signs that a rock could have possibly hit it. My safety was at risk because I could have crashed and broken glass rained down on me. There were no warning signs and the vehicle has not been inspected yet, but it will be.

I am writing regarding a serious vehicle safety issue involving my 2023 Hyundai Tucson Limited purchased from on [XXX] with approximately 61,000 miles. About one month after purchase, during a drive from Pennsylvania to Florida in October 2025, the vehicle experienced multiple dangerous steering and collision-assist malfunctions in clear highway conditions. The first incident occurred in Virginia while adaptive cruise control and steering assist were active at approximately 70 mph. Within seconds, the steering wheel aggressively turned left and right, causing the vehicle to tip and nearly roll until the driver manually regained control. Later during the same trip, while making a normal lane change with the right turn signal activated, the vehicle falsely detected a collision despite no vehicle being present. The vehicle then veered left toward traffic and unexpectedly slammed on the brakes. Following these incidents, all assist sensors and automated driving features were manually disabled for safety reasons. However, the vehicle has continued intermittently triggering false collision warnings and emergency braking events with no vehicles present, creating additional near-accident situations involving surrounding traffic. I recently had the vehicle inspected by Hyundai after initially believing this may only be a calibration issue. Due to financial and scheduling limitations, I delayed service until this month, but I now understand this issue is far more serious and systemic. Two separate mechanics have advised me the vehicle has major safety-system malfunctions making it unsafe to drive. There are no reported accidents or braking issues on Carfax. I am also concerned this appears to be a widespread issue affecting this vehicle model, yet I received no notification regarding related safety concerns or recalls until conducting my own research. One mechanic stated“I’m surprised this car hasn’t killed you yet. I wouldn’t put my own kids in this vehicle." INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

The reverse beeping is just too loud for an Hybrid and many people online agree. I fully agree with having mandates for electric vehicles for safety concerns however they should not be so loud that they are louder or near as loud as a commercial truck and disturb residents. In fact Hyundai responded to the complaints by re-designing it for 2025 and newer facelifts but won't give any services to upgrade it to newer versions. I fully believe that Hyundai should and must offer services to use the new updated VESS.

The car has 57,000miles and needed a new transmission. Safety concern of the transmission failing while driving. There was a persistent and worsening rubbing noise once the car ran for 20 minutes or so. 4 visits to the dealer later, they confirmed the issue and Hyundai issued a warranty to replace the transmission with a remanufactured transmission. When I asked the dealer what happened, he said this was there 4th one in a few weeks. There were no indicator lights or anything besides the noise to indicate there was a problem.
