The picture
Is the Hyundai Ioniq or Honda Accord 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 or electric hatchback that has averaged about 94 complaints per year over six years, with 13 recalls. The most common owner-reported trouble spots are electrical glitches, power-train hiccups, and fuel/propulsion faults. Many complaints describe warning lights, sudden deceleration, or loss of power, which can be unsettling in daily driving. Overall, it shows a moderate complaint rate for its class, but the electrical and propulsion issues are worth understanding before buying.
Honda Accord
The Honda Accord is a midsize sedan with a much higher complaint volume: about 452 per year over ten years, plus 38 recalls. Owner reports cluster around engine problems, electrical failures, and forward collision avoidance warnings. Some complaints describe serious events like simultaneous loss of power steering and braking, or unexpected automatic braking. That said, the Accord's longer production run and higher sales mean more reports overall, so per-vehicle risk may be lower than the raw totals suggest.

Owners frequently report warning lights for the auto hold and electronic parking brake, often within months of purchase. These glitches can disable driver-assist features and may require repeated dealer visits.
Complaints include unexpected reverse acceleration, loss of reverse gear, and a bucking loss of power while driving. These symptoms suggest transmission or hybrid control issues that could leave a driver stranded or in a dangerous situation.
Reports mention high-voltage isolation faults (DTC P0AA6) and sudden deceleration without warning. For a hybrid or EV, these faults can affect battery safety and drivability, and some owners say dealers were slow to address them.
The Auto Hold feature sometimes malfunctions, showing a 'conditions not met' message and deactivating the electronic parking brake. Owners also report the car continuing to move or accelerate after braking, which is a clear safety concern.
“06/08/21 first day I brought my new car Hyundai Ioniq 2021 model at Hyundai Lincolnwood. After use the car about 2 months, the engine light has been showing up that something wrong about the auto hold and EPB. So I made an appointment for inspect in the next…”

Owners describe rattling noises while accelerating, rough transitions between EV and gas modes, and sudden loss of speed with multiple dashboard alarms. These issues can indicate internal engine or hybrid system problems that are costly to diagnose and repair.
Complaints include simultaneous failure of electronic power steering and braking at highway speeds, as well as TPMS warnings followed by tire failure. Such failures can cause near-collisions and leave the driver with little control.
Reports describe the system braking unexpectedly on open roads or with adaptive cruise control engaged, sometimes twice on the same route. This can startle the driver and increase the risk of a rear-end collision.
Some owners report a persistent rotten-egg or sulfur odor, often linked to fuel or emissions components. While not always a safety defect, it can indicate a problem that affects performance and cabin comfort.

Buyer analysis
Hyundai Ioniq or Honda Accord: which should you buy?
The Hyundai Ioniq has far fewer complaints per year (about 94) than the Honda Accord (about 452), but the Accord's higher total reflects a longer production run and more vehicles on the road. In practice, the Ioniq's issues tend to be electrical and hybrid-related, while the Accord's span engine, electrical, and driver-assist systems. Neither is problem-free, but the Ioniq's lower complaint rate may mean fewer trips to the shop for the average owner.
Key differences
- The Ioniq averages about 94 complaints per year, while the Accord averages about 452 per year, though the Accord was sold in higher numbers over a longer period.
- Ioniq owners most often report electrical warnings, auto hold/EPB faults, and hybrid power loss; Accord owners report engine rattles, sudden power steering/braking failure, and unexpected automatic braking.
- The Ioniq has 13 recalls, including charging module and traction battery issues; the Accord has 38 recalls, covering hybrid power control software, fuel pumps, and air bag sensors.
- Crash-related complaints are much higher for the Accord (162 vs. 25), but this may reflect its larger fleet and longer time on the road.
- Check for any stored hybrid or electrical fault codes, especially P0AA6 or auto hold/EPB warnings, as these are commonly reported.
- Test the reverse gear and acceleration from a stop for any hesitation, bucking, or unexpected movement, which owners have reported.
- Listen for rattling noises during acceleration and feel for rough transitions between EV and gas modes, which owners frequently mention.
- Test the forward collision avoidance and adaptive cruise control at highway speeds to ensure they do not brake unexpectedly or show false warnings.
Before you buy
- Obtain a full vehicle history report and confirm all recalls have been performed, especially for hybrid and electrical systems.
- Have a certified mechanic scan for diagnostic trouble codes, particularly hybrid battery, power train, and brake system faults.
- Test-drive both city and highway conditions, including reverse, hard braking, and adaptive cruise control if equipped.
- Inspect tires, brakes, and suspension for uneven wear or damage that could relate to reported handling or braking complaints.
- Ask the seller for maintenance records and check if the vehicle has been subject to any lemon-law buyback or repeated repair visits.
