In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
If the car is not driven for about 5 days, it will not start. I told this to the local Honda dealer and he says I am not alone. All modern Accords do this because the computer performs a self-check every 2-3 hours and this drains the battery.
Driving southbound on 101 south on sunny clear day 65 degrees with almost full fuel tank and 2 battery bars (almost empty) and climbing up incline on 7 degree grade and check engine light went on and lost all power and car completely slowed down to a stop (luckily was able to pull over with no problem)
Very loud roaring noise when driving about 52-54mph (and intermittently at other speeds). This not engine noise, but seems to a glitch in the automatic noise cancelling system that causes a feedback loop resulting in an alarming roaring sound that can cause driver to panic or otherwise be distracted from driving safely
The 2018 Honda Accord hybrid's active noise canceling (anc) system is flawed. The car howls, roars and can even produce a loud boom at certain conditions (ie. Light acceleration, engine rpms ~2250, colder temps (<50degf), starting @ 30+mph but worst is @ ~52mph). I took the car into my local Honda dealer who confirmed the problem.
Rear speakers continue to make horrible scratchy sound when driving and using audio. Speakers have already been and problem still continues. Vehicle was stationary, in motion, on a city street or a highway, turning, braking, etc

What does NHTSA's "Electrical System" heading cover?
Wiring, modules, batteries, charging, infotainment and driver displays — NHTSA's broadest heading. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
