HYUNDAI IONIQ ELECTRIC

ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY

Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Kona Electric and 2020 Ioniq Electric vehicles. The lithium-ion (Li-ion) battery may short-circuit.

Risk: An electrical short in the Li-ion battery increases the risk of a fire.

ELECTRICAL SYSTEM:SOFTWARE

Hyundai Motor America (Hyundai) is recalling certain 2017-2019 Ioniq electric vehicles. An unstable electrical ground may cause the vehicle to enter a fail-safe mode with reduced acceleration and power. In certain conditions while in fail-safe mode, the vehicle may accelerate after the gas pedal is released.

Risk: Unexpected acceleration following gas pedal release can increase the risk of a crash.

VEHICLE SPEED CONTROL

The instrument cluster (digital speed display) on my 2019 Hyundai Ioniq Hybrid Limited has repeatedly turned off while driving. This issue happens randomly, especially in warm weather or after the car has been sitting in the sun. Sometimes the cluster reboots (I hear the start-up chime, the display shows the headlight icon, etc.), other times it remains blank for several minutes. This affects the ability to see speed, gear, and warning indicators, posing a serious safety risk. I’ve had to pull over multiple times because I couldn’t see how fast I was driving. Turning the car off and on sometimes resets it, but the issue returns. I am not the only one experiencing this. Other Hyundai owners across multiple models and years have documented the same or similar problems, including: 2024–2025 Hyundai Santa Fe (cluster and HUD flicker, total blackout) 2025 Hyundai Tucson Hybrid Limited (cluster goes blank within 3 days of ownership) 2022 Hyundai Santa Cruz (cluster resets while driving) Hyundai Ioniq 5 (cluster flickers, reboots mid-drive, sometimes blanks) 2022–2023 Hyundai Palisade (recall #217 for illegible or blank cluster) These reports appear across NHTSA, Reddit, IoniqForum, TucsonForum, and Hyundai Santa Fe and Genesis forums. Some owners had to replace their entire cluster or HUD; others received full vehicle replacements after failed repairs. Hyundai should investigate this as a pattern defect in digital instrument clusters across multiple product lines. I am submitting this to protect future drivers and urge NHTSA to act.

POWER TRAIN

While driving the transmission started driving rough and the car was stuck in ev mode. Wouldnt even go back to hybrid mode. I kept driving until all my battery range was exhausted and lost acceleration and had to pull over the side of the highway. It was late at night so there was no one around or behind me, otherwise I would have been hit. Once stopped the car would not move at all so I called a tow to get me off the highway. I was away from home and had to tow it 120 miles back to the local dealer. The engine clutch actuator failed and ruined my transmission and left me stranded in the middle of the night!

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

When approaching a turn, I let off the accelerator but the car didn’t stop accelerating. Instead, it gently kept accelerating. I applied the brakes and the car started slowing down but not at the same rate I was applying brake pressure. Therefore I floored the brakes to try coming to a complete stop. Sadly, the cars ABS system did not engage, half of the car hopped over the curb at about 20 mph. I was able to steer the car back onto the road where it finally came to a stop but acted like it wanted to keep going until full blackout power loss happened. The car was deemed a total loss by my insurance company American Family. Essentially, the vehicle malfunctioned causing the accelerator to stick which caused the car to be harder to control than designed. The car malfunctioned by not engaging the ABS system as well. There is a recall on this exact problem for the 2017-2019 model but not for my 2020 even though it was manufactured during that campaign. It all happened very quickly and I was very lucky this did not involve another vehicle.
