2019 HYUNDAI IONIQ ELECTRIC

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!
