The picture
Is the Hyundai Ioniq or Hyundai KONA more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Hyundai Ioniq
The Hyundai Ioniq is a compact hybrid/electric that owners report as having frequent electrical gremlins, especially around the 12V battery and regenerative braking. Complaints also highlight powertrain and fuel system issues that can cause sudden power loss or hesitation, making it a car that may need more attention than average. While it has a lower complaint rate than the Kona, the nature of the issues—like unexpected braking or loss of power—can be unsettling for a first-time buyer.
Hyundai KONA
The Hyundai Kona is a subcompact crossover with a much higher number of engine-related complaints, including overheating, jerking, and hesitation. Owners also report electrical problems like horn failure and a case of being trapped in the liftgate. With a slightly higher complaint rate and more severe engine issues, the Kona appears to have more serious reliability concerns that could lead to costly repairs or safety risks.

What actually goes wrong
The problems owners report
The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.
Hyundai Ioniq
- 01ELECTRICAL SYSTEM365
- 02POWER TRAIN100
- 03FUEL/PROPULSION SYSTEM100
- 04ENGINE56
- 05SERVICE BRAKES53
Owners report the 12V auxiliary battery hold-down bracket left unsecured after service, and regenerative braking levels changing without input, causing unexpected strong braking. These issues can lead to electrical failures and potential safety hazards.
The car may fail to switch between EV and hybrid modes, causing rumbling and loss of power. There are also reports of unintended acceleration in reverse, which is a serious safety concern.
Sudden deceleration and hesitation when shifting from reverse to drive are reported, which can be dangerous when pulling into traffic. This suggests potential issues with the propulsion control system.
Loss of power and abnormal rattling sounds when accelerating are reported, along with check engine lights. This can lead to reduced performance and potential breakdowns.
“Following a 12V auxiliary battery replacement at Dick's Hillsboro Hyundai [XXX] , April 3, 2026), the battery hold-down bracket was left completely unsecured. The retaining bolts were absent, (later found loose in the cargo tray area). The battery terminal co…”
“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…”
Hyundai KONA
- 01ENGINE390
- 02UNKNOWN OR OTHER134
- 03ELECTRICAL SYSTEM134
- 04POWER TRAIN95
- 05FORWARD COLLISION AVOIDANCE56
The most common issue is engine overheating, which can occur suddenly and lead to a crash if not handled quickly. Owners also report jerking and hesitation, especially at low speeds, indicating possible transmission or engine management problems.
Recurring horn failure is a notable issue, with multiple service visits needed. There is also a report of being trapped inside the liftgate, which is a serious safety concern if the emergency release fails.
The vehicle jerks and hesitates when accelerating from a stop, especially after long drives. This can make city driving uncomfortable and potentially unsafe in traffic.
While not detailed in the sample, this system is a top complaint area, suggesting possible false activations or failures that could affect braking or warnings.
“I was driving to work on a normal day under normal circumstances when a check engine light won my dashboard. Seconds later my car started showing car is over heating. I immediately swayed from the speed lane to the side of the road almost getting into a crash…”
“My Kona N Line is not functioning well. Especially after driving for a longer period of time. About 60% of the time, upon letting go of my brake, the car jerks. Going from 0 - 5 mph is the worst. The car definitely hesitates many times. Again, it is when I ha…”
