2025 Hyundai Ioniq 6 Recalls, Ratings & Complaints

Incident: October 11, 2026 · Filed: October 12, 2026

We were driving and vehicle suddenly showed multiple warnings including check forward/side safety system, check change lane assist, check inattentive driving warning, check lane safety system and then things went away and it showed 4 needs attention represented by triangle with exclamation point. We also seemed to lose power steering assist. It could drive but was "heavy". We were on highway trying to figure out what to do and what was wrong. Isolated stretch of highway at night. Suddenly the multiple warning flashed again. We were trying to determine what to do. The car seemed to drive fine except power steering seemed heavy. Suddenly a violent "jerk" occurred with vehicle sending us into the other lane. Fortunately, we were by ourselves on the highway and no crash or other vehicle impacted. Instantly, after the violent "jerk" the car was back to normal. Steering normal and all warnings went away. We have a video and pictures of the incident. It seems related to functional 12 V battery based on my assessment. There was a recall of the ICCU and software to charging the battery.

Shift-by-wire system completely locked up, the vehicle refused to power down, and potentially the brake pedal switch failed. The vehicle became unresponsive while I was in a parking garage. Thankfully this didn't happen on the road. After spending over an hour trying random "tricks" found online, I eventually managed to turn the car off and restart it. I still don't know how. Through my research, I discovered that I am far from the only owner experiencing this terrifying defect. There are numerous documented cases online of this exact vehicle platform refusing to shift out of gear or shut down. For your reference, here are just a few links detailing similar experiences: * [XXX] (The thread I found while stranded) * [XXX] (Documenting identical shift-by-wire and park malfunction issues) * [XXX] (Documenting related EV platform gear engagement failures) Unfortunately Hyundai thinks that the vehicle is "driveable". I completely disagree and find that this is a serious safety glitch for a car. They offered a BBB AUTO LINE arbitration. A severe life-safety defect that traps a driver without vehicle control requires immediate regulatory oversight, not internal arbitration.

Today I was driving on highway when all of a sudden the psi went from 22 to 0 on my back left tire. We pulled over and the tire came off the rim and somehow sliced the tire. I checked and there were no punctures and nothing in the tire. According to tow truck driver the back right tire is getting ready to do the same thing. This is the second time within a couple months I got a flat. I've never had issues with tires of this type on other vehicle The tow truck brought vehicle to Simmons Rockwell in Elmira. Waiting for them to call

Accelerator stopped working on the highway. Dash displayed an electrical system warning and speed dropped to a crawl. The hazard came from being on an interstate at night and the closing speed for everyone behind us. Fortunately we were by an exit and could drive in the shoulder at 25 mph to it. Vehicle was towed to Stew Hansen Hyundai in Clive, IA. 12-volt battery, ICU and high-voltage fuse were replaced. My VIN did not appear in NHTSA recall lookup results for this issue.

NHTSA COMPLAINT — SHORT VERSION I am reporting a persistent, unresolved, safety-related steering defect in my 2025 Hyundai Ioniq 6 (leased 10/12/2024). Beginning in September 2025 at approximately 15,412 miles, the vehicle exhibits: (1) uncontrolled steering wheel shifting left and right at highway speeds; (2) hard pulling to the left when accelerating or decelerating; and (3) the vehicle swaying or jerking within its lane without driver input. I described the issue to the dealer as "pretty dangerous to drive" — this language is documented in Repair Order #XXX. Despite 6+ documented repair attempts over 9 service visits from September 2025 through May 2026, the defect remains unresolved. Repairs attempted include: two 4-wheel alignments, road-force balancing, steering angle sensor calibration, front camera calibration, new front view camera installation, and a complete steering gear box (R-MDPS) replacement. The vehicle was out of service for 129 documented days. CRITICAL ADMISSION: Dealer Repair Order #XXX(11/5/2025) explicitly states that Hyundai's Technical Service Bulletin procedures for this steering defect only apply at speeds of 40 MPH and below, and that "above that speed there are too many variables." The defect occurs at highway speeds above 40 MPH. This is a written admission that no manufacturer-approved repair procedure exists for the defect as experienced. Hyundai Techline Case #XXX was opened in January 2026. After Techline involvement and new camera installation, the technician's own repair order states "concern still present" after road testing. Hyundai Motor America corporate case #XXX was opened, and Hyundai has now stated they cannot process a buyback or lemon case. The vehicle remains unsafe to operate at highway speeds INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6

"While driving a 2025 Hyundai Ioniq 6 at approximately 10,000 miles, the vehicle experienced a sudden, catastrophic Integrated Charging Control Unit (ICCU) failure with no advance warning. The vehicle instantly experienced a total electrical shutdown while the car was on the ramp. The failure completely bypassed and disabled standard safety redundancies: the electronic parking brake/emergency brake system failed , and the 12-volt backup battery died instantly, making it impossible to activate the hazard lights. The vehicle became a completely invisible, immovable dead weight on an active roadway, presenting an imminent, extreme threat of crash, injury, or death to myself and surrounding motorists. I was holding my breath and have to call AAA road side emergency assistance, only when an external battery is connected I could move the car in "Turtle Mode" to a safe spot.The manufacturer has replaced the ICCU, but the total failure of critical emergency safety and braking indicators poses a fundamental safety defect that needs federal investigation."

The contact owns a 2025 Hyundai Ioniq 6. The contact stated that while reversing out of the garage, the vehicle suddenly stalled, with the message "12-Volt System Deactivated" displayed. The vehicle was towed to the local dealer, where it was diagnosed and determined that the computer control module had failed and needed to be replaced. The contact stated that the computer control module failure was caused by using a faulty phone charger inside the vehicle. The computer control module was replaced, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 300.

I was driving at 60mph. I heard a sudden pop that felt like it came from behind me / under the car. While I glanced to see if I ran over something (I did not), the car suddenly felt like it was about to stall. It was slowing down quickly and dramatically. My safety was in danger as I quickly dropped speeds in heavy traffic on a freeway without warning. I was able to maintain control, and I turned my hazards on. I noticed that I was maintaining speed around 35-40 mph (no matter how heavy I hit the accelerator), and I moved to the right lane and continued while wondering if my car would survive all the way home. Luckily I was only about 1 mile from my house at that point, so I proceeded at a low rate of speed and ultimately made it home. It was scary, sudden, and put me and others on the road in danger. A couple of warnings popped up saying "Electrical System issue" and something else that was related to electronics. The vehicle was towed to the dealership that night, and diagnostics and repairs began the following day. The problem has been confirmed by the dealer to be an ICCU failure that needs to be replaced. There were zero warnings prior to the failure--the car was working perfectly up until that moment. Anything is available for inspection, but as I mentioned it's being replaced as we speak so the broken / malfunctioning part wouldn't be there anymore if someone looked at it.
