What 6 owners told NHTSA about the 2019 Hyundai Ioniq Electric

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.

THIS IS A FOLLOW UP TO COMPLAINT NUMBER 1# 1360258 SUBMITTED IN SEPT. IN PARTICULAR, I HAVE HAD MULTIPLE DEALERS REPLACE A WATER PUMP AND RELATED ASSEMBLIES FOR A TOTAL OF 3 REPLACEMENTS SINCE AUG. THIS WAS THEIR EFFORT TO DEAL WITH THE ELECTRICAL SYSTEM ISSUES THAT HAVE RESULTED CONTINUED INCIDENTS OF ERRATIC AND UNCONTROLLED APPLICATION OF THE REGENERATIVE BREAKING (NOT BY DRIVER), SHUTTING OFF OF ANY ABILITY TO ACCELERATE THE CAR WHILE DRIVING, AND COMPLETE SHUTOFFS OF THE CAR WHILE DRIVING ON FREEWAYS, I.E. ALL LIGHTS OFF, NO RESPONSE FROM INSTRUMENTS EXCEPT FOR BREAKING TO A STOP. I REALIZE YOU MAY BE SHORT HANDED DEALING WITH COMPLAINTS, BUT I HAVEN'T RECEIVED ANY CONTACT SINCE FIRST REPORTING THIS AND WAS WONDERING IF I SHOULD EXPECT ANY? OR IS THIS ONLY ONCE YOU HAVE SO MANY RELATED COMPLAINTS TO INVESTIGATE? OR PERHAPS YOU NEED SOME MORE VERIFIABLE DOCUMENTATION OF THE EVENTS? THANKS FOR YOUR HELP.
