As I was driving home from work, a loud POP went off under my car, and sirens began to go off. I was given a critical error, and told to immediately contact a dealership. My car began to slow, and would only go 25 mph. Luckily for me I was within a few miles of a dealership, but if I wasn't so fortunate this would have been a much larger issue. The ICCU has failed, despite already getting Hyundai's recall for this issue performed. I am now without my car for an unknown quantity of time.

Today, I had a scary situation on my 2024 Hyundai Ioniq 6 limited. While backing out of a parking space, I put my foot on the brake to place the car in drive and the car kept rolling back no matter what I did and almost crash into the car park across. I was able to finally stop the car by placing it into park repeatedly. I was inches from striking the car across when it finally came to a stop. I then attempted to place it in drive again and no dice. I had to turn the car off and back on to get it to respond and place it back to drive. Anyone else experience this helpless feeling? Quite scary. This vehicle has had the various ICCU updates performed.

Driving on middle lane of fast freeway with kids in the car. The car began beeping lights of an electric malfunction, a 12v battery malfunction, an ICCU malfunction and then started to slow down all the way to 3 miles per hour and then it stopped in the middle of the freeway. A car behind us almost crashed into us and would have killed us. I feel very u safe and Hyundai will not do anything about it. It’s a one year old lease of a 2024 EV with barely 10k miles on it. They are not fixing in time and it also shows a recall that they didn’t accommodate or were able to schedule.

Sep 8, 2024 Crash

To date, our experience driving the 2024 Hyundai Ioniq 6 has been a total "NIGHTMARE." We've had 2 "TERRIFYING ACCIDENTS" within the first 6 months of leasing this vehicle, Both caused by "Unintended Acceleration Issues," the car "randomly" accelerates, on it's own! 1st ACCIDENT (4/25/2024) - As my wife pulls into our driveway, the car suddenly accelerates (un-commanded) and smashes in the garage, the damage was over $8,000 dollars, (we paid out of pocket) ... Thank God, she was not HURT! State Farm Insurance paid over $20K to repair the car, we paid $500 deductible. It took over 10 weeks to complete all repairs. After we got the car back, my wife was "very apprehensive" to drive for two weeks, finally, able to summon enough courage, she got back behind the wheel and then came the 2nd ACCIDENT( 8/25/24) - While pulling into a Jamba Juice parking spot, the car did it "AGAIN," (unintended acceleration), Jumping the curb, plowing into greenery, shrubs and block wall. Again, 'EXTREMELY" fortunate no one was hurt of "KILLED!" The car was towed to SLO Hyundai Dealership, then back to Kaisen Collision Center, for 2nd time, all within 6 weeks! The repair completion date, is estimated for 9/13/24 with approximate cost at $13K dollars, to date. "REGARDLESS" of all that, we feel blessed to be "WALKING AWAY," from the vehicle, (literally & figuratively)! We are "DONE" ... the car is a total "DEATH TRAP." Immediately following ACCIDENT #2, we called SLO Dealership to report (2nd accident), stating, we are "FINISHED" with the car & "REFUSE" to drive it again! SLO Dealership was apologetic and stated they could "VOID OUT" Lease Agreement, "ONLY" if we paid dealership, roughly $8K dollars (Citing: "Car Depreciation," after "YOUR" Two Accidents - CarFax report). Now, this where the rubber meets the road, we vehemently refrut dealerships allocation, we take total culpability, paying them an extra $8K to return this (heavily documented), "FLAWED" vehicle.

This incident just happened around 9:50pm. I have a 2024 ioniq 6 SEL with 2900 miles. I lost power to my motor while going below 45 mph. The gage that shows acceleration and recharge, zeroed out, showing absolutely nothing. Once I came to a complete stop, I had to restart the car for the accelerator to work. I am on 37% charge. This is not a low charge. There were no warning lights or sounds. I had smart ventilation on as well as lane assist. The steering wheel control became very sticky as the car began to lose power. I am thankful that this was a low speed occurrence and not highway speeds. The fact that I couldn’t accelerate means that if something was oncoming, I was in essence a sitting duck. This is the first time the problem has occurred in my vehicle and has not been inspected.
