2017 Hyundai Ioniq Electric recalls & complaints
Source: NHTSA, updated daily. Last checked 2026-10-19. Recalls apply to specific VINs — run your VIN to confirm.
2 safety recalls, most serious first
1. Electrical system
What's wrong, in plain English: Wiring, modules, batteries. Short circuits can cause stalls or fires. 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.
What could happen: Unexpected acceleration following gas pedal release can increase the risk of a crash.
The fix: Dealers will update the EPCU (Electric Power Control Unit) software and repair the ground wiring, free of charge. Owner notification letters were mailed February 9, 2022. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 215.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2017 IONIQ ELECTRIC.
- Book a repair at any authorized Hyundai dealer. Quote NHTSA campaign 21V944000 (manufacturer code 215).
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-855-371-9460.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.

If you take your eyes off the road for a second, the vehicle will veer into other lanes. It requires constant vigilance beyond what is required for normal driving to remian in your lane. This is a well-documented issue online involving the ball…
