I was pulling into my driveway and I heard a "clunk" and then an error appeared on the dashboard saying "Check electric vehicle system." My 12V battery then died. After recharging the 12V battery with an external charger, the "Check electric vehicle system" message came up again when I started the car, and I could only drive a block or…
Our all-electric AWD Hyundai Ioniq 5 has an issue where the rear motor electric oil pump (EOP) overheats and ceases to function when the problem occurs, which disables the rear motor and effectively causes the car to become a front-wheel drive vehicle with a "hesitation" in the acceleration.
Failure of the Vehicle Power Supply system. ICCU failure. Car was alerting and would not go over 24mph. This is the result of a recall that I had already brought in the vehicle for in April, but they only performed a Pass/Fail test and at the time it "passed" so they didn't replace the ICCU and fuse that is required to be replaced.
First indication something was going awry was when attempting to charge the car. Heard normal click indicating charge had started, but no audible announcement that charging had started. Car started throwing "Check electrical system," then power plummeted and became unresponsive to accelerator, followed by "Stop car.
Driving on the freeway at approximately 70 mph, the car lost the ability to accelerate and started to lose speed. I had my foot on the gas but the speed was dropping. There were no warning lights, messages, or other alerts prior to the loss of acceleration. The screen remained on during the loss of acceleration but a phone call was lost.
