Owner report 11271746 · 2019-10-29 (October 29, 2019)
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 CL…

Owner report 11473991 · 2022-07-14 (July 14, 2022)
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…

Owner report 11452656 · 2022-02-18 (February 18, 2022)
The city I live is located on top of a hill/low mountain. When I drive uphill by following speed limits to my home the car often can't keep recommended speed (45 mph). The speed drops significantly(can go even 25 mph) and unpredictable. At the beginning I believe the car was able to keep the speed but it slowly started losing the power. The risk is that a vehicle behind might not expect such behavior from my car and also changing lanes is tricky because it can't accelerate and it moves slower than other cars on the road. I've contacted dealer…
