While driving on the interstate my 2023 Ioniq 5 SEL RWD experienced a failure with the front radar system stating that it was blocked. In reality there was nothing physically blocking the system which was verified on multiple pullovers to check the front of the vehicle. This caused the critical forward safety functions, HDA system, lane change assist functions, regeneration system, and smart cruise control to all be disabled. The car is available for inspection upon request and I have video of the car displaying the fault messages during the trip as it happened on multiple occasions.

pre-purchase inspection list. Back to the
