“I bought a 2019 Hyundai Nexo Fuel Cell on 04/29/2020 from Lithia Hyundai of Mission Hills without been notified of the two existent recalls with no remedy yet available from Hyundai. In fact, these Recalls shown in the Carfax report, were undisclosed by giving me to sign the last page "as a confirmation I was going to receive it complete". At the end of the process, I received a USB with the purchase documents and it was until two days after when I printed all documents, I found out about the recalls. Is it fraud?”
“WHEN THE CAR IS MOVING, A "REGENERATIVE BRAKE SYSTEM FAILURE" MAY OCCUR. WHEN THIS ERROR OCCURS, BRAKING EFFECTIVENESS IS DRAMATICALLY REDUCED AND THE CAR'S SPEED IS LIMITED TO 13 MPH. ADDITIONALLY, THE CAR WILL NOT CREEP FORWARD OR HOLD POSITION WHEN THE BRAKE IS RELEASED, POTENTIALLY ALLOWING THE CAR TO ROLL BACKWARD WHEN THE BRAKE IS NOT APPLIED. THE FAILURE OCCURS MOST COMMONLY WHEN THE CAR IS CREEPING FORWARD IN TRAFFIC, BUT CAN ALSO OCCUR AT FREEWAY SPEEDS. TURNING OFF THE CAR, RESTARTING IT, AND PULLING FORWARD - IN THAT ORDER - WILL CLEAR THE BRAKE FAILURE WARNING LIGHTS AND RETURN THE CAR TO NORMAL OPERATION UNTIL THE NEXT FAILURE. TIME BETWEEN FAILURES CAN BE AS LITTLE AS A FEW MINUTES AND AS GREAT AS A FEW DAYS. THE FAILURE SETS DTCS IN THE VEHICLE ECM BUT THESE CODES HAVE NOT BEEN SUFFICIENT FOR TECHNICIANS TO IDENTIFY THE FAULTY COMPONENTS. THE VEHICLE WAS RETURNED TO CUSTOMER WITHOUT THE TECHNICIANS OBSERVING THE FAILURE OR PERFORMING ANY FIX. THE CAR THEN FAILED AGAIN A FEW DAYS LATER AND HAS BEEN RETURNED TO THE DEALER FOR FURTHER ASSESSMENT.”
