NHTSA lists 3 safety recalls and 43 owner complaints for the 2017 Hyundai Ioniq Hybrid. Most complaints involve electrical system (16) and engine (13).
Hyundai Motor America (Hyundai) is recalling certain 2017-2018 Ioniq HEV and Ionic PHV vehicles previously recalled under recall number 18V-704. The Power Relay Assembly (PRA) located underneath the rear seat may overheat.
Hyundai Motor America (Hyundai) is recalling certain 2017-2018 Hyundai Ioniq Hybrid and 2018 Ioniq Plug-In Hybrid vehicles. The Main Relay within the Power Relay Assembly (PRA) may have inadequate connections between its contacts, causing increased electrical resistance.
Hyundai Motor America (Hyundai) is recalling certain 2017 Hyundai Ioniq Hybrid vehicles. The Hydraulic Clutch Actuator (HCA) inner oil seal may leak, allowing oil to accumulate in the cap area, possibly resulting in an electrical short.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Vehicle/Component: Hydraulic Clutch Actuator (HCA) / Electrical / Hybrid Powertrain Associated Recall: NHTSA Campaign Number 18V-260 (Hyundai Campaign 176) Complaint Description: My 2017 Hyundai Ioniq Hybrid is experiencing a dangerous failure of the Hydraulic Clutch Actuator (HCA), causing the "Check HEV" warning light to illuminate and severe drivability issues. This vehicle was previously included in NHTSA Campaign 18V-260 (Hyundai Recall 176). However, the manufacturer's chosen remedy in 2018 was inadequate and failed to permanently cure the safety defect. According to Hyundai’s defect report, the root cause of the recall is internal manufacturing burrs on the HCA housing cylinder block that degrade the oil seal over time, allowing fluid to leak onto electrical components and create a fire hazard. During the 2018 service visit, the dealership only replaced the outer "phase cap" rather than replacing the defective housing block itself. The underlying manufacturing defect (the internal burrs) has now completely destroyed the internal seals, resulting in a live manifestation of the exact safety defect and fire risk described in the original recall.

“After the Dealership, Michigan City Hyundai (MCH), performed part of the needed repairs, I became aware of what could/would have been a fire hazard (as evidenced by brownish/black heat spots, on the metal cover of the hybrid battery, under the rear seat. To maintain its recall-denial, MCH blames the hybrid starter generator (HSG) for the damage to the hybrid battery. The noted heat-spots prove otherwise - the power relay assembly (the subject of one of the recalls related to my car), and its malfunction and consequent generation of excessive heat, is what caused severe damage to the hybrid battery. The other failed component (hybrid system generator - HSG) is directly related to the hybrid clutch actuator (HCA), which is the subject of the 2nd recall affecting my car. The malfunction of the HCA is what damaged the HSG. The NHTSA database shows no open recall affecting my car VIN, is because dealer IL093 (who sold me the car around April 2025), logged both recall remedies as applied in Hyundai's internal database. The selling dealer (IL093), which claims to have completed the Power Relay Assembly and Hydraulic Clutch Actuator recalls on my vehicle, was under the…”
“I was driving my two young daughters (ages [XXX] and [XXX]) to school, in clear conditions, when we suddenly heard a static-like noise. Instantly, the car's check engine light and check EV battery light came on, and I realized I could no longer accelerate. I immediately pulled off to a safe shoulder and turned the car off and then back on. The car would not move. I exited the vehicle and THANKFULLY left my car door open. I walked around the vehicle and immediately called my husband for help. Within seconds, my [XXX] daughter, who was sitting directly behind me in the rear driver's seat, told me she saw smoke. I went to open her door and realized it was locked. My key fob and door lock would not unlock her door. I reached through my seat to open her door and instantly saw the smoke coming from a vent just to the left of her legs. I unbuckled her and pulled her out, and climbed through the vehicle to get my [XXX] unbuckled and safely out of the vehicle. I cannot stress enough how grateful I am that my car door was left open because I don't believe I would have been able to break the glass to get my daughters out. The could have easily died. Within a minute of the…”
