When a car is in the process of passing me on the left during a left hand curve on the highway at highway speeds, the rear left radar sensor seems to have set off a forward collision warning. This caused the ioniq5 to do an emergency collision brake. I had to press on the accelerator to cancel the emergency brake while the other car passed me on the left. There were no cars in front of me that would have triggered a frontal collision emergency brake.

FORWARD COLLISION AVOIDANCE: WARNINGS
The forward collision system will intermittently erroneously detect objects in front of the vehicle while stopped or in motion. While driving on the freeway, this will cause the car to engage the emergency braking system endangering those in and around the car. While stop to the stoplight, this causes the front detection alarm to go off. The dealership has reproduced the error and tried software updates and replacing sensors, but the problem persists.

While backing into my driveway if a car passes in front on the street my car will not continue backing up. This also happens in parking lots. While backing out of my driveway onto the street and staying in the lane closest to the driveway, traffic in the far lane will cause the car to stop moving even though the street is more than wide enough to accommodate both cars without crossing the double yellow lines. As I live on a busy street this can cause an accident. In both cases turning off the parkin sensors with the dashboard button has no effect.

My wife was parking the 2024 ioniq and it lurched forward at a high rate of speed and slammed into another car parked in our driveway and drove that vehicle through our home garage door. She feels certain that her foot was on the brake, but even if she accidentally slipped and appleid the brake the forward collision system should have prevented the accident additionally the impact occurred with such force it is unlikely due to human error as it pushed our very heavy 4Runner back 3 feet and thorough a closed garage door.

LANE DEPARTURE: ASSIST
When on a highway with lane-keeping assist engaged, the car sometimes steers into the left-hand lane. It seems to happen most often when the road bends to the right. The car straddles the lane divider into the fast lane to the left. This occurs in otherwise perfect conditions: sunny, dry days on roads with clear white stripes demarking the lanes. I must fight with it to get it back in the proper lane. This is very dangerous. I'm convinced it will cause a high-speed crash. Another driver I spoke with said she had seen the same problem and wouldn't use the lane guidance because of it. I'm extremely cautious when I use it now. The problem has happened multiple times.

Backing vehicle out of driveway and went to engage brakes and they did not engage. began rolling backwards down street with steep grade. Kept stepping on brakes with no response. Had to turn into a parked vehicle to keep from rolling down steep grade and potentially off a substantial cliff. Happened today and dealership said that it may be because the "battery for the brake" had not received a charge from the main battery. Very dangerous and never disclosed. If I had not taken evasive action I could have easily been killed. Car is being dropped off at collision center today but is available for inspection. There were no warnings or other symptoms.

BACK OVER PREVENTION: WARNINGS
The collision detection and early warning system behaves in a manner that deceives the driver into believing a collision is imminent every time the car begins to reverse out of a normal parking spot you find in a parking lot. Despite the car knowing the vehicle is in the reverse gear the driver will begin receiving audible, visible, and haptic feedback alering the driver of an imminent collision. After pausing the procedure of vacating a parking spot to determine where the car has detected a collision the HUD indicates that it is the sensors in the front of the car that were detecting a possible collision despite the car being in reverse and moving away from the objects the front sensors detected. Furthermore, these alerts don't begin until you begin reversing which makes the situation very dangerous for all parties as the driver is now having to freeze and reassess again before proceeding. But the most dangerous problem about this scenario I am describing is that I as a driver have now gotten used to these "false" positives and as a result I assume any alerts I here while backing out are just the front sensors being noisy when it could be someones child behind the car I am driving. Fix this! How was your safety or the safety of others put at risk? High risk. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No. Working as intended from all research I have found online from other Ioniq 5 owners.
