Verbatim from NHTSA complaints, newest first
“The contact owns a 2019 Hyundai Tucson. The contact stated that while driving 50 MPH, there was a burning odor coming from the vents, with the battery warning light illuminated. The vehicle was taken to the service center, where it was diagnosed with alternator failure. The contact was informed that the alternator needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that the alternator had been replaced three times with aftermarket parts and a fourth time with an OEM part. After inspecting the alternators, the contact noticed that the copper wires inside each alternator were black due to the failure. The contact was concerned that a previous recall associated with the failure did not properly fix the vehicle. The manufacturer was made aware of the failure by telephone, and a case was opened. The contact also requested a buyback of the vehicle. The failure mileage was approximately 61,000.”
“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.”
“The contact owns a 2019 Hyundai Tucson. The contact stated while the contact's husband was driving, the contact noticed an abnormal loud sound. In addition, the contact noticed smoke coming from the front of the vehicle. No warning lights were illuminated. The contact noticed an unusual odor in the interior of the vehicle. The contact's husband drove the vehicle to the shoulder of the road. The contact stated that the engine seized. In addition, the contact stated that the smoke and the unusual odor subsided. The vehicle was towed to the contact's residence. In addition, the contact stated that when the failure occurred, the contact's minor children were occupants of the vehicle. The contact stated that the minor children were frightened. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure. The contact was informed of an open recall associated with the contact's VIN, NHTSA Campaign Number: 20V543000 (Service Brakes, Hydraulic). In addition, the contact was informed that her contact information was not updated in the database. The failure mileage was approximately 49,400.”
“On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire. The fire ultimately spread and resulted in the vehicle becoming a total loss. This created a serious safety concern and placed me at risk. I later learned there was a recall associated with the vehicle. However, I never received any recall notices because Hyundai reportedly had the wrong address on file. Had I been properly notified of the recall and potential safety risks, I would have done everything in my power to ensure the vehicle was inspected, repaired, and safe to drive. Because I was unaware of the recall issue, the vehicle continued to be operated without my knowledge of the potential danger. The incident caused significant financial and transportation hardship, including loss of reliable transportation and additional financial strain. Hyundai later reached a determination regarding the matter, but I remain concerned about the serious safety risk and the fact that I did not receive proper recall notification before the incident occurred. I am submitting this complaint because I believe the…”
“The contact owns a 2019 Hyundai Tucson. The contact stated that upon entering the vehicle, there was water overflowing from the front passenger's side floormat. The vehicle was taken to the dealer, but the water entry point could not be determined. Additionally, the contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, where a brake sensor was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where another brake sensor was replaced; however, the failure persisted. The vehicle was taken to the dealer, who diagnosed that the wiring harness had sustained water damage and corrosion due to a clogged sunroof drain. The dealer determined that the wiring harness needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the repair should be covered by the manufacturer because the failure was a factory defect. The manufacturer was not contacted. The failure mileage was approximately 30,000.”
“On three occasions while the vehicle was idling, the dashboard screens and interior lights went completely black, and the steering wheel jerked abruptly in my hands. This sudden electrical failure creates a serious safety concern, particularly if it were to occur while driving at higher speeds. The dealer has not been able to reproduce the problem. There were no warning lamps, messages or other symptoms prior to the failure. There were no warning lamps after the problem occurred. The vehicle has been inspected multiple times by a Hyundai dealership. On one occasion, the dealership retained the vehicle for approximately two months but reported no definitive findings despite error codes being present. On a later visit following another failure, no error codes were recorded. The dealership replaced the head/stereo unit and confirmed no active recalls, yet the issue continues. This problem first occurred while the vehicle was covered under an extended warranty, but due to its intermittent nature, it was not resolved before the warranty mileage threshold was exceeded. I have since found numerous similar complaints online from owners of the same model year describing…”
