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 t

The 12v system in my vehicle is defective, resulting in the vehicle failing to operate. Since I have only operated it about 4 times, i am unable to state whether the issue would occur while the car was being driven. I have had the car checked by the dealer twice, and it is now at the service department with an unknown date for "repair". The diagnosis from the second dealer service department directly conflicts with what the first dealer service department said. Additionally, I have discovered that this is a known issue with this vehicle model, and Hyundai has failed to address it. I have filed a formal complaint with Hyundai, as the vehicle is still under manufacturers warranty. Incidentally, there is a newly issued recall that I suspect is related to the 12v system, as well.

When ABS engages briefly on a wet surface, there is an incomplete transition from regenerative braking to friction brakes, resulting in a hard pedal that does not actually engage the brakes. This is very dangerous and I have experienced this loss of braking force multiple times when stopping in the rain and a tire is on a slippery manhole cover or crosswalk line. Braking force is reduced significantly for a second or two until the friction brakes are engaged. If the vehicle is rolling in Neutral, the friction brakes work as designed with no delay. It is only during normal driving when the regenerative braking is involved that this issue can be replicated.

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.

THE CAR WAS STOPPED AT A STOP LIGHT WHEN WE WERE STRUCK FROM BEHIND BY A FORD F150. WE WERE PUSHED INTO THE STOPPED VEHICLE IN FRONT OF US (VERY MINOR DAMAGE IN FRONT). I WAS IN THE PASSENGER SEAT AND MY HEAD BOUNCED OFF OF THE DASHBOARD. MY DAUGHTER WAS IN THE SEAT BEHIND THE DRIVER AND HER HEAD WAS BOUNCED OFF THE BACK OF THE DRIVERS SEAT. THE SEAT BELTS KEPT US IN OUR SEATS BUT THE SHOULDER BELTS FAILED TO ENGAGE. THE CAR HAS SINCE BEEN TOTALED DUE TO DAMAGE FROM THE REAR.

I HAVE HAD 4 INCIDENTS SO FAR OVER THE LAST MONTH, ALL LASTING UNDER 5 SECONDS. IN EACH CASE, THE REGENERATIVE BRAKING SWITCHES TO A DIFFERENT LEVEL WITHOUT ANY INPUT FROM THE USER. THIS PRESENTS AS WHAT FEELS LIKE A LEVEL 3 (STRONG) BRAKING WHEN NONE WAS ON AND NO FOOT IS NEAR THE BRAKE, OR IF THE REGEN BRAKING WAS TURNED ON (IN ONE CASE TO LEVEL 1), IT SHUTS OFF MOMENTARILY. DURING THESE INCIDENTS, THE BEHAVIOR IS ALSO IRREGULARLY CHANGING BETWEEN FOR EXAMPLE HARD BREAKING (LEVEL 3) FOR A SECOND AND THEN FLUTTERING IRREGULARLY BETWEEN HARD AND LOW LEVELS. IN ONE INCIDENT, THE CAR COMPLETELY SHUT OFF (AND STAYED IN NEUTRAL) AFTER AN INCIDENT HAPPENED WHILE ACCELERATING FROM A STOP. THE CAR THEN GLIDED TO THE SIDE OF THE ROAD WHERE I WAS ABLE TO RESTART THE CAR AS NORMAL. IN EACH CASE, THE INCIDENT OCCURS WHILE IN MOTION, NOT TOUCHING THE BRAKE PEDAL BUT MAY BE CURRENTLY SET ON DIFFERENT LEVELS OF REGEN BRAKING (IT'S HAPPENED BOTH IN LEVEL 0 (NONE) AND 1 (LOW). THE BEHAVIOUR IS NOT HOWEVER TRIGGER BY MANALLY CHANGING THE REGEN LEVEL BUT SEEMS TO JUST SPONTANEOUSLY HAPPEN WHILE SMOOTH DRIVING. MOST CASES OCCURRED ON CITY STREETS BUT ONE OCCURRED ON A SMOOTH HIGHWAY AT ABOUT 60MPH. NONE OF THE INCIDENTS HAVE CREATED AN ACCIDENT AS I WAS NOT VERY CLOSE TO ANY CAR IN ANY CASE. I DO HAVE TWO INVOICES FROM SEPARATE CAR DEALERS LOOKING AT THE PROBLEM. IN THE FIRST CASE, THEY COULD NOT FIND ANY ERROR CODES BUT THEY FOUND THE WATER PUMP WAS LEAKING AND REPLACED THAT (PER A TSB). FOLLO
