There are 7 owner-reported speed control & cruise complaints for the 2022 Hyundai Ioniq 5in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While driving on the highway in foggy conditions, the smart cruise control system and forward safety system suddenly shut off while I was going 70 miles an hour. This almost resulted in a car rear ending me due to the sudden deceleration. The following day, with clear weather, the same issue happened again despite nothing appearing to have caused this issue while I was driving. This is a very serious concern to suddenly stop on a highway.
While driving, the 'check EV system' light comes on, intermittently what will happen is that when stopped the car will put itself in park, when it is in park I can not get it out of park, thus unable to move forward, it has also happened while reversing (and not stopped). I need to cycle the car on and off a bunch of times in order for it to finally turn back on. This is very dangerous while on the road stopped in a busy intersection and has potential for a crash. I have brought it to a dealer 4 times and they do not know what is wrong and cannot fix it. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Hyundai's connected car service (bluelink) suffered an outage that resulted in driver profiles on many Hyundai vehicles being deleted/reset. No notice was provided and the profiles were not recovered. As a result, the vehicles did not funtion as expected. Driver assist settings were set to default (steering, braking, and acceleration functions included). Hyundai provided instructions on how to set up a new profile in response rather than restoring the customer data to their personally owned hardware (car).
Accelerator failed to engage on two occasions. 5/18/2023: First while driving on highway at 70MPH. Car slowed down gradually and I pulled onto shoulder. 5/19/2023: Again the next day driving 35 MPH. Pulled off road onto private driveway. On both occasions I turned car off and back on and it resumed normally. Fortunately no accident or traffic problem. I brought car to the dealer (Country Hyundai Northampton) to be checked and they could not find a problem.
Hi! My vehicle went under a recall repair last month. Once completed, the acceleration significantly decreased in the ECO drive train mode. The other modes are working as before. I have been advised that this recall service was required by the NTSB. There are reports of this occurring on credible websites as well. I did report it to Hyundai, they didn't believe me. So, I am reporting this to you. Please fix my car!
I was driving on the highway using advanced highway assist and the car became completely unresponsive. I was traveling 75mph on a major highway with a semi behind me and one to my right in the slow lane. The car stopped accelerating and I was unable to resume driving. I was forced to coast to a stop on the side of the highway. I had my daughter with me and were I not able to safely maneuver between the semi trucks, we could have been killed or seriosuly injured in a high speed crash.
Vehicle parked and unattended. Shifter control unit failed and vehicle rolled away. Vehicle front damage.
