Hyundai Tucson electrical problems

My 2022 Hyundai Tuscon came to a complete stop on the highway in Colorado twice in the last 2 months for no apparent reason. There weren't any obstacles or cars in front of me that would have caused the car to brake suddenly. I had passengers in the car and we were jolted forward. The air bags did not inflate and we were not hit from behind, but we could have been severely injured or killed. There are numerous "phantom braking" reports like this here on the NHTSA site for the 2022 model as well as more recent models. Yet Hyundai has only issued recalls for the 2025 and 2026 models. How are you addressing this issue?

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.

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.

The 2019 Tucson has 60,413 miles. My daughter drives it very low mileage - a couple of miles a day back and forth to school. Friday she was driving and the car lost engine power and it stopped driving. No warning lights. There was a cloud of smoke and it smelled like burning plastic. She was on a busy road but pulled over and quickly exited the vehicle. I had it towed and the mechanic says the engine oil was empty and the engine has seized. We do regularly scheduled oil changes. No lights or warnings and the car just stopped in traffic.

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.

While idling at a standstill (in a drive-thru queue), my 2018 Hyundai Tucson suddenly experienced a severe engine overheat, causing the vehicle's air conditioning system to immediately blow hot air and shut down. The vehicle was brought directly to an authorized Hyundai dealership (Chapman Hyundai on [XXX]) for an emergency inspection.The dealership's certified technicians confirmed that the electric Engine Cooling Fan Assembly completely failed and subsequently caused the main Front Wiring Harness and Fuse Box to physically melt. The dealership documented this catastrophic electrical and thermal meltdown under Repair Order #XXX.This is a critical safety defect. A melted engine wiring harness poses an immediate and severe risk of an electrical short circuit, sudden vehicle stalling in live traffic, or a catastrophic under-hood engine fire. Because this component controls the primary cooling of the powertrain, its failure creates an extreme hazard to the vehicle occupants and surrounding traffic. Hyundai must investigate this component failure before it results in a thermal fire incident or an accident due to sudden power loss.

On 5/14/2026, while driving southbound on I-95 with my pregnant wife and young daughter, my 2025 Hyundai Tucson (approx. 7,500 miles, purchased new 10/2025) experienced multiple critical safety failures. Two days prior, the heads-up display (HUD) intermittently failed to activate. On 5/14, traveling at 65-70 mph near [XXX] , the brakes auto-applied without driver input. Simultaneously, the instrument cluster and HUD went completely black, eliminating all speed and vehicle status information. This recurred intermittently. Near [XXX] , the brakes auto-applied with full force, locking all four tires and bringing the vehicle from approx. 70 mph to a complete stop on the active interstate. Two trailing vehicles spun out and left the travel lane to avoid rear-ending us. A multi-car pileup was narrowly avoided. The vehicle was taken to Pearson Hyundai in Midlothian, VA. They diagnosed and replaced a faulty wiring harness. Immediately after the repair, driving northbound on I-95 back to [XXX] (5/16), the lane keep assist/lane departure system began pulling the steering wheel into the adjacent lane without driver input, repeatedly and unpredictably at highway speed. The dealer repair did not resolve the all defects. Within a three days this vehicle exhibited: (1) total instrument cluster/HUD failure, (2) uncommanded emergency braking at 70 mph causing two other vehicles to take evasive action (3) uncommanded steering input into an adjacent lane. These failures created immediate risk of serious injury or death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
