SERVICE BRAKES
The Hyundai Ioniq was designed with a dual clutch system for the electric motor and gas motor. This was done to disengage and engage either separately when necessary for low power, regen braking, etc. However, this design heavily impacts the behavior of the brakes and safety of the vehicle overall. When the brakes are applied, the ECU will turn off the gas engine to conserve gas in regen braking mode. Additionally, the ECU will downshift the transmission. Downshifting the transmission and disengaging the gas engine become an issue because conducting both actions removes significant resistance in braking. Causing the vehicle to lurch when the downshift occurs while also increasing stopping distance. This downshift can be felt when braking as both loss of brake power and vehicle lurch. The system also does not account for this brake power loss by increasing brake booster response.

VISIBILITY/WIPER
The display does not always show reverse camera when backing up. Not often, but does occur. I can use mirrors, etc. Annoying as it is a learned experience with this car, and when reverse camera is not operational it does limit view behind car due to design. I did capture video this time as it isn't first occurrence. I was in parking lot where I could do this without endangering anyone.

SERVICE BRAKES, UNKNOWN OR OTHER
On a recurring basis, the warning lights come on for”AUTO HOLD” and “EPB” or emergency parking brake. Car continually beeps and gives warning until car is reset. During this time, the cruise control will turn off, causing safety issues during travel. Also, the other safety features seem to stop working during the time this warning is activated. Emergency stop, et cetera. Only activated when vehicle is operating under highway mph. Typically local roads with stops/starts trigger this issue. Mechanics have no idea what is wrong with vehicle warning. I see online that this is a common issues with Hyundai Ioniq. A possible recall is needed to investigate/fix this issue as local dealerships arent aware of a solution.

ENGINE
The car engine started to stall, the engine light came on and advised me to shut off engine then I pulled over and smoke immidiatley filled the cabin and outside the hood. My engine could have blown up. Had I not pulled over so quickly my car would have caught fire and I would have died. Yes the Hyundai Folsom inspected the car and listed issue was a hole in the engine block. They stated it was caused by premature wearing of the rod bearings and refused to repair. The ONLY warning happened within seconds of the car stalling and failing to accelerate before I pulled over. The first symptoms was a noise I couldne place 5 days prior. It was a mild knocking sound that was subtle.

ELECTRICAL SYSTEM:ADAS
The hold app doesn't work very well. Since first check up in 2022, I mentioned to garage that I have to push on button every time I need to use it as opposed to pressing on it and removing it when desired. However, not the main issue. I get in the car, Auto Hold (which usually appears when I press the button) will suddenly pop on my screen but won't work. The break won't hold, it's just there. It scares me that it has something to do with the breaks themselves in the long run. I've spoken about it twice before and the garage stated that they couldn't see it so couldn't do anything about it. The issue popped on my dashboard one day and I drove straight to the dealership. They said they had no loaner and would call me. This was more than a month ago. I'm tired of trying to get them to address the issue and hoping that I'm not the only one having it.

FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL, POWER TRAIN
Many times, when I back out of my driveway into the intersection in front of my house the vehicle hesitates for several seconds when shifted from Reverse to Drive. I am in a situation where I cannot accelerate if needed out of the intersection. This is a safety issue in my opinion. The dealer was not able to replicate the problem, even though it happens frequently and has not provided a solution. One time, on a long road trip, while climbing a grade the vehicle could not achieve normal highway speeds (could only get to 20-30 mph). Big rigs were right behind the vehicle and were not happy having to slow down. Again creating a big safety hazard.

SERVICE BRAKES
Integrated Brake Accuation Unit failed per dealer repair location. Codes indicated on attached repair invoice receipt. (Document is Uploaded). This was a very expensive repair. Per dealer service advisor and technician they had never seen this before. 2 brake lights on the dash indicated major brake failure. The vehicle was immediately taken to the dealer for repair. See additional details regarding concern, cause. correction, and parts replaced on invoice. If this had not been repaired immediately, this could have put others at risk and caused an accident. Although there are several internet references to brake problems with this model of Hundai Ioniq Hybrid, there are no recalls. The powertrain and engine are warrantied for 100K miles and the batteries have an original lifetime owner warranty. Due to the critical nature of a braking system, I believe braking systems on hybrids for this part should have a lifetime warranty. I want to make it clear that parts that wear out due to use for example brake pads, rotors, master cylinder etc. are not what I am referencing. Since the integrated brake accuation unit is a part commonly seen on hybrid products, I think this a part that warrants investigation and recall. This investigation may go beyond the Hyndai hybrid products. Due to the expense of the repair, I believe this repair could put the owners of all hybrid auto products at risk.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
The EPB light appeared on the dash panel of the car on 7/13/2023, along with the EPB light, the cruise control, the auto hold function, and the electric parking brake stopped functioning. The light will disappear on a restart and reappear after a period of time. It is indeterministic when the light will reappear on the dashboard. I have tried to contact the nearest dealer in an attempt to get the car inspected for safety reasons, however, the dealer was unavailable and Hyundai national customer service was unable to help. Hyundai's national customer service representative was also being deceptive as they transferred me to a dealer that is 425 miles away from the location I told them while giving me the impression that they were transferring me to a local dealer. The car was eventually inspected by two different Hyundai dealers. The first dealer informed me that there was a short on the wire which caused the error. However, due to the fact I was moving at the time, I could not wait for them to fix the car at that moment. They stated the vehicle was safe to drive and that I could bring the car to the new dealer once I moved to the new location. When I brought the car to the new dealer, instead of the wiring error, they stated that the radar of the car had failed. Since then, they have performed repairs on the car and the error has not yet occurred. This is a significant concern of safety due to various reasons. First, the electric parking brake is an important component of the car, as in the event of a break failure, the electric parking brake is the only backup to ensure the car can be stopped before any catastrophic event. Furthermore, according to the dealer, the actual component that has failed is the radar. However, I do not recall, at any moment, the car has warned me that the radar has failed. This could cause any reasonable person to assume the radar is functioning properly and believe that the forward collision-avoidance assist is still active with no

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Shortly after purchasing my Ioniq (roughly 2 months into ownership) my dashboard started beeping with warning signs for my EPB and auto-hold brake. I panicked and parked my car and tried to turn off the functions because I thought I had accidentally turned them on but they wouldn’t turn off. This would continue at random for roughly 7 more months until it would stay on for weeks at a time. I was told there was nothing the dealership could do about it and was asked about my oil changes. I get my oil changes within the intervals set for the vehicle and it does not seem to affect if the lights come on or off. They beep constantly and also the EPB and Auto-hold features do not work when the light comes on, the fail. It’s a safety risk as when I do try to engage them they don’t work and makes me fearful that they will short and work at random times which is a huge concern.

ELECTRICAL SYSTEM, STEERING, VISIBILITY/WIPER
My lcd screen constantly goes black. A couple times the steering wheel locked the wipers and washer fluid went off at the same time. I had to hit the brakes and power the car on and off to reset it while making a turn. When having my window motor replaced for the SECOND time my dash where the speed is at all when black while driving on the freeway. I had to pull over and restart the car. My paint and my clear coat is separating on my trunk. It looks white not oxidation just separating and white. My driver side door button to lock the car kept getting stuck and was locking and unlocking. this left the possibilities of my car getting stolen from the door lock and the window motor leaving my window half down. My safety and the safety of others is obviously at risk with the electrical malfunctions. My local dealership left my issue’s unresolved for currently FIVE months with little to no compensation. I guess the life of my family and everyone else on the road is only $420.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER, FUEL/PROPULSION SYSTEM
What component of system failed or malfunctioned? Sudden deceleration, not sure what system this is a part of. Is it available for inspection upon request? No, I don't know what is causing the problem so have not been able to have the specific system looked at. How was your safety or the safety of others put at risk? I have been driving on the highway and experienced sudden deceleration of the vehicle multiple times over the past four years. Not being able to control deceleration puts me and the people around me at risk for collision. I am also at risk of being stranded far from home where assistance may not be readily available. Has the vehicle or component been inspected by the manufacturer, policy, insurance representative or others? Yes, by four separate dealerships. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Check engine light came on shortly after deceleration, battery power could then be seen at a critical low.

STEERING
The steering is "sticky" causing the vehicle to zig-zag, rather than track straight, especially at highway speeds. If you take your eyes off the road for a second, the vehicle will veer into other lanes. It requires constant vigilance beyond what is required for normal driving to remian in your lane. This is a well-documented issue online involving the ball bearings and lubrication of the intermediate shaft of the steering column.
