Dear Customer Care, I am the owner of a 2023 Hyundai Kona AWD purchased brand new from Vision Hyundai West Henrietta, NY. I paid for the vehicle in full with a cashier's check totaling over $31,000. At just 64,000 miles, the vehicle has become undrivable-experiencing loud noises, jerking, and no acceleration. I was driving and car would not move. These symptoms are clearly drivetrain-related and should be covered under Hyundai's 10-year/100,000-mile powertrain warranty . When I contacted the dealership, I was incorrectly told my roadside coverage had expired at 36,000 miles, Hyundai Warranty Escalation Letters which contradicts Hyundai's stated policy of 5 years/unlimited mileage. Additionally, I requested a loaner vehicle due to the urgency and distance (I'm 80 miles away), but no one followed up, leaving me stranded and without any transportation options. …
Rodent damage found during 1-year maintenance. This is an increasing problem that is under-reported. Damage was found before any wires were effected, however, the wiring was exposed and would have caused a malfunction had this not been detected by technician. 1. Automakers across the board are using cheaper, soy-based elements to wrap wiring and customers are having to deal with the result of subpar parts. 2. With automakers increasing the time allowed between oil changes, customers are given a false sense of functionality in the vehicles they drive. 3. Automakers that advertise "free maintenance" should not be allowed to limit maintenance to once per year or every 5,000-8,000 miles, as more prudent inspection would prevent customers from unknowingly having their cars devoured by rodents.
Horn no longer works when pressed at 11,396 miles. Manufacturer will not offer loaner vehicle. Vehicle is not safe to drive without horn. Manufacturer does not seem to care that it's broken and will not expedite the repair process. I will have to drive this vehicle for approximately a month with no horn. My safety is put at risk as I cannot warn other drivers of impending danger and cannot warn other drivers they are about to hit me. The manufacturer has not yet inspected the vehicle. The inspection will take place on August 21st. There were no warning indications before I attempted to use the horn and it didn't work. It's possible that the horn has been broken for a while.
The horn is not working in my vehicle. I found this out today when I almost had someone collide with my vehicle while I was on the highway, not once, but twice. I was unable to use my horn to alert the other driver. I called Hyundai and they said it is not covered under warranty and this is a known issue with my vehicle. I have only had the vehicle for 3-4 months and this should not be happening. I cannot safely drive without a horn and if something happens to me or my vehicle and Hyundai knows its an ongoing issue with this year, make, and model, I am not sure what I can do. Please make this right.
I have been having electrical issues since I bought this car. The radio screen goes black for no reason, the clock changes time on it's own the Android auto only works intermittently. The tire lights come on and say there is 0 psi in the tires. Right now it says that 1 tire is low but the psi is the same in all 4 tires. I think this car was damaged during Hurricane Ian and the dealership still sold it to me. I have already brought it to the dealership to be fixed and it still has issues.
Horn is not working. When the horn is pressed from the driver's seat, no noise is made. Checked fuse in engine fuse box compartment. 15A fuse is ok (not blown, etc). Checked with spare 15A and that did not work either. Reported problem to dealership and they plan to investigate and repair. Google search indicated this is not the first Hyundai Kona to have this issue. This should be more looked into by regulatory boards.
