After purchasing the vehicle on 8/2/25, I discovered it had outstanding safety recalls that were neither addressed nor disclosed by the dealership at the time of sale. I have since taken steps to fix these safety issues, but the dealer's failure to inform me or resolve the recalls before the sale put me at unnecessary risk. I urge the NHTSA to review the dealership's records from 8/2/25 to hold them accountable for selling a vehicle with unresolved safety defects that compromised my safety. It is not allowing me to add case card with report, only case card available as of today.
