NHTSA lists 1 safety recall and 6 owner complaints for the 2019 Hyundai Ioniq. Most complaints involve electrical system (4) and service brakes (3). The EPA rates it 55–136 mpg combined.
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.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“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,…”
“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.”
