FUEL/PROPULSION SYSTEM

We are reporting a suspected thermal runaway incident involving our recently purchased used 2023 Hyundai Ioniq 5 and have significant concerns regarding the vehicle's safety. **Vehicle Information** * Purchased XXX, 36,662 miles * Clean inspection and no accidents per Carfax **Incident Timeline – XXX** Between 6:00 and 6:30 PM, while traveling northbound on [XXX] just past the [XXX] exit in [XXX], the vehicle struck a white piece of road debris that appeared flat, similar to Styrofoam (video available). There was no immediate loss of vehicle function. [XXX] The vehicle was then moved to the driveway for inspection after a low coolant warning appeared. Damage to the underside near the driver's side and observed blue coolant leaking from the area. The coolant reservoir under the hood was empty. Based on online guidance advising against driving a vehicle with a coolant leak, we decided to leave the vehicle parked in our garage overnight and arrange a flatbed tow to a Hyundai dealership the following day. The garage door was closed, and the vehicle was **not charging**. At approximately 8:10 PM, a burning smell was detected inside the home. Upon opening the door between the house and garage, smoke was observed. The family immediately evacuated, and XXX was called at 8:12 PM. The fire department arrived at approximately 8:18 PM and found the garage filled with smoke. At 8:30 PM, firefighters removed the vehicle from the garage. At 8:35 PM, flames were observed beneath the vehicle. Firefighters applied water directly to the fire until 11:00 PM, after which the vehicle was removed. [XXX] [XXX] [XXX] Manufacturer was contacted; denies any liability due to debris. However, we believe inadequate safety design contributed, including soft protection shield and poor location of coolant.

ELECTRICAL SYSTEM

The ICCU malfunctioned. Safety impaired because it likely impacted the ADAS, which concurrently failed. Yes, the problem has been inspected and confirmed by a dealer.

AIR BAGS

There is a yellow air bag (SRS) safety restraint critical wire harness underneath the seats and it's loose and hanging down touching the floor with lots of slack, very easy for a water bottle or any object to roll under there and pull it loose, which would disable a critical passenger safety system. This issue is reported by many drivers including myself, photos attached are from multiple people's experiences with this issue.

SERVICE BRAKES

The vehicle repeatedly displays a "Stop Vehicle and Check Brake System" warning together with an ABS warning, accompanied by a loss of normal braking response. On XXX, while driving at approximately 60 mph on I-85 northbound near Exit XXX in [XXX], the warnings appeared and the brakes did not respond normally. I was maintaining a substantial following distance, and the braking system restored itself before I reached the point of needing to brake hard, so no crash or injury occurred. Had hard braking been required in that window, I do not believe the vehicle would have stopped as commanded. This is a recurring fault. The vehicle, purchased certified pre-owned and still under the Hyundai factory warranty, has been taken to the dealer (Ed Voyles Hyundai, [XXX]) three times for the same condition. On the first visit the Integrated Electronic Brake (IEB) unit was replaced; on the second, the Smart Junction Box was replaced; on the third, the dealer removed an aftermarket tracking device wired to the data link connector and referenced Hyundai TSB 24-GI-011H, representing the problem as corrected. The braking-loss event on XXX occurred after that repair. The vehicle has been out of service approximately 30 days total. Because the failure is an intermittent loss of braking response at highway speed, I consider it a serious safety hazard and no longer drive the vehicle.
