The EV6's main issue is electrical (401 complaints), often ICCU failure; the Accord's top issues are engine (985) and electrical (863). Source: NHTSA owner complaints.
The picture
Is the KIA EV6 or Honda Accord more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
KIA EV6
The Kia EV6 is an electric crossover that has been on the road for about five years. In that time, owners have filed 535 complaints, with the vast majority—401—centering on the electrical system. Many of those reports describe a specific failure: the Integrated Charging Control Unit (ICCU) quits, which stops the 12-volt battery from charging and can reduce power while driving. That pattern suggests that while the EV6 can be a satisfying electric car, a buyer should be prepared for potential charging and electrical headaches.
Honda Accord
The Honda Accord is a mainstream midsize sedan with a much longer track record—10 years of data and 4,438 complaints. The most common trouble spots are the engine (985 complaints) and the electrical system (863), but owners also report a high number of forward collision avoidance issues (821). Some of those complaints describe sudden warnings, loss of speed, or braking problems. With 38 recalls and 160 crash-related reports, the Accord has a broader set of potential problems, though many are covered by recalls or warranties.

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.

- 02POWER TRAIN96
- 03FUEL/PROPULSION SYSTEM96

Owners frequently report the Integrated Charging Control Unit (ICCU) failing, which stops the 12-volt battery from charging and can cut motive power. This can leave you stranded or cause reduced performance, and it often appears after about 15,000 miles.
Some complaints describe reduced motive power tied to the same ICCU failure, meaning the car may not accelerate or drive normally. This is a safety concern because it can happen while moving.
Although the EV6 is electric, this category captures charging-related faults that owners say lead to loss of power or charging problems. These issues can make the car undrivable until repaired.
Several owners report persistent error codes (like P056216, C160404, C28B186) even after dealer repairs, suggesting that some electrical gremlins are hard to fully fix. This can mean repeated shop visits.
“I own a 2025 Kia EV6 Wind RWD. At approximately 14,655 miles, the vehicle experienced a confirmed Integrated Charging Control Unit (ICCU) failure that resulted in loss of 12-volt charging and reduced motive power. On August 1, 2026, while reversing the vehicl…”

Owners report noises, loss of speed, and multiple dashboard alarms (brake, hill descent, ABS) that can appear suddenly at highway speeds. In some cases, the car loses power, which is a serious safety risk.
Complaints include tire pressure monitoring (TPMS) warnings that may be followed by tire failure, and rodent damage to wiring harnesses even on new cars. These can lead to unexpected breakdowns or costly repairs.
Many owners say adaptive cruise control, lane keeping, and automatic braking systems throw intermittent warnings or fail to work. This undermines driver-assist features that many buyers expect to be reliable.
Some complaints mention brake-related alarms and critical failure messages, which can accompany the engine and electrical issues. Brake problems are especially concerning because they affect stopping ability.
“I purchased this vehicle at 0 miles in July 2025 from Honda Accord in Pensacola Florida. I reported in July 2025 that there was a noise and I was unhappy with the vehicle and would like to exchange the vehicle within the 30 days months later, the noise got lo…”

Buyer analysis
KIA EV6 or Honda Accord: which should you buy?
The Kia EV6 has far fewer complaints per year (about 107) than the Honda Accord (about 444), but the EV6's complaints are heavily concentrated in a critical electrical failure that can disable the car. The Accord's issues are more varied and numerous, but many are covered by its 38 recalls. In practice, the EV6 may have fewer total problems, but when something goes wrong it can be severe; the Accord may need more frequent attention but has a broader support network.
Key differences
- The EV6's top complaint is a single, recurring electrical failure (ICCU) that can cause loss of power, while the Accord's complaints are spread across engine, electrical, and driver-assist systems.
- The Accord has 38 recalls versus 11 for the EV6, meaning more known defects have been officially addressed.
- The EV6 averages about 107 complaints per year; the Accord averages about 444 per year, but the Accord has been on sale longer and sells in much higher volumes.
- Owner reports for the Accord include sudden loss of speed and braking alarms, while EV6 reports often mention charging failure and reduced power.
- Ask for the service history and specifically whether the Integrated Charging Control Unit (ICCU) has been replaced or updated; a prior failure may recur.
- Check for any stored error codes (especially P056216, C160404, C28B186) using a scan tool, as owners report these persisting even after repairs.
- Test the forward collision avoidance systems (adaptive cruise, lane keeping, automatic braking) thoroughly; intermittent warnings are a common complaint.
- Inspect tires and TPMS sensors closely, as some owners reported a TPMS warning followed by a sudden tire failure.
Before you buy
- Obtain a full vehicle history report and confirm all recalls have been performed for the specific model year.
- For the EV6, have a certified mechanic check the ICCU and 12-volt charging system, and scan for any stored codes.
- For the Accord, test all driver-assist features and listen for engine noises during a test drive, including at highway speeds.
- Ask the seller for any warranty information, especially for the EV6's electrical components and the Accord's engine and electrical systems.
- Consider a pre-purchase inspection by a mechanic familiar with the specific model to catch model-specific issues.
