FUEL SYSTEM, OTHER,ELECTRICAL SYSTEM
The contact owns a 2021 Hyundai Nexo. The contact received notification of NHTSA Campaign Number: 22V258000 (Fuel System, Other, Electrical System) however, the part to do the recall repair was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was made aware of the issue and confirmed that parts were not yet available. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The contact had not experienced a failure. VIN tool confirms parts not available.
The car does not automatically brake to avoid collision. I have tested the car by going straight into a large object either another car or person in front of my car and it will not brake. In addition the hydrogen sensor is not working properly as I have already been informed of from their recall number 225 NHTSA Recall 22V-258 which I just received a few days ago. I am dissappointed that it took 3 months for Hyundai to notify me of this very serious safety issue and I am now calling the NHTSA to see what options I have to return this vehicle as I do not feel safe driving, operating, or even parking my car at my home with a hydrogen sensor that is faulty as that is a very serious fire hazard.
