NHTSA complaint #11733868

Owner complaint summary

(NHTSA Tracking Number 11726105) I am updating my existing complaint regarding my 2024 Hyundai Tucson (NHTSA Tracking Number 11726105) for an ongoing safety concern involving an intermittent warning chime while driving. This issue began shortly after I purchased the vehicle in Nov 2025 and has been reported to the dealership multiple times over several months. The warning chime occurs randomly while driving without any visible warning message or dashboard alert. This creates uncertainty because I do not know what the vehicle is trying to warn me about, which is distracting and creates a safety concern while driving. The dealership previously replaced both front seatbelt buckle assemblies after identifying intermittent high resistance as a possible cause. However, after that repair was completed, the warning chime occurred again while I was driving to the dealership for a follow-up visit. This confirmed that the issue was not fully resolved. I immediately returned the vehicle to the dealership, and they are now performing further diagnosis. I was advised that if the issue reoccurred, the next possible areas for diagnosis could involve the instrument cluster or the control module, both of which are safety-related systems connected to warning alerts and seatbelt functions. In addition, during this same visit, the dealership confirmed there is an actual oil leak requiring repair. This is significant because when I first raised this concern after an outside inspection in December 2025, I was told it was likely leftover residue from a prior oil change. The dealership has now confirmed it is a real leak and kept the vehicle for repair while providing a loaner vehicle. Because this vehicle was sold as Certified Pre-Owned and these safety and mechanical concerns continue shortly after purchase, I remain concerned about the reliability and safety of the vehicle.
