2021 Honda Accord Problems

2021 Honda Accord problems owners report most

2021 Honda Accord problems are documented in public: owners have filed 294 complaints with NHTSA, the earliest in 2021 and the most recent in 2026. Sorting those by the component the filer named puts the electrical system clearly first, at 76 of the 294 complaints, about a quarter of everything filed.

A complaint is not a repair bill and not a defect finding. It is one owner telling the regulator something went wrong. What makes the count useful is the concentration: when one component takes 26 per cent of everything filed on a car, the pattern is doing more than chance.

Against the 2020 car, this model year has drawn 28 per cent fewer complaints (294 against 407). The 2020 car was led by its forward collision avoidance instead, so the pattern shifted between the two years.

Of those complaints, 17 describe a crash and 1 describes a fire. Filers reported 9 injuries.

Recalls on the 2021 Honda Accord

A recall means the manufacturer or the regulator found a safety defect, and the repair is free at a franchised dealer however old the car is. There are 4 recalls on this model year. Your own car may be covered by some, all or none of them, so check the VIN rather than the model.

In owners own words

These are complaints filed about the electrical system, quoted as written. They are one persons account rather than a diagnosis, and they are here because a symptom described by a driver is easier to recognise than a component name.

SUBJECT: A REQUEST FOR HONDA CORPORATE INVESTIGATION AND GOODWILL ASSISTANCE - 2021 HONDA ACCORD I am submitting a formal complaint regarding serious and recurring electrical and safety-related problems with my 2021 Honda Accord. 1. Numerous dashboard warning lights and safety-system warnings illuminate simultaneously. 2. The vehicle repeatedly displays messages instructing me to "See Dealer." 3. The power door locks repeatedly click and cycle as though they are attempting to lock or unlock on their own. 4. The stereo, on its own, scrolls through buttons and bluetooth blinking through all th

Vehicle: 2021 Honda Accord Sport Subject: Intermittent Electrical Malfunctions, Multiple Safety Warnings, and Loss of Acceleration I am reporting ongoing safety concerns involving my 2021 Honda Accord Sport. On multiple occasions, my vehicle has displayed several dashboard warnings, including brake system, electric parking brake, vehicle stability assist, hill-start assist, adaptive cruise control, and electric power steering warnings. These warnings have appeared intermittently in the past and sometimes disappeared on their own. On October 18, 2026, while traveling on the highway at approx

The infotainment touchscreen in my 2021 Honda Accord Hybrid intermittently registers inputs that I am not making. The screen experiences repeated “ghost touches,” accompanied by random beeping and clicking sounds. During these episodes, the system changes GPS screens or navigation directions, changes music or audio settings, turns the audio on or off, closes applications, and opens other applications without any input from the driver. During these "ghost" episodes, the touch capability seems to also be intermittent preventing from leaving the current screen or app that the "ghost" clicks on.

The infotainment/touchscreen system in my 2021 Honda Accord is malfunctioning and experiencing what is commonly referred to as “ghost touching.” This issue has been occurring since approximately March 2026. While I am driving, the touchscreen will randomly make selections on its own without me touching the screen. This is especially concerning when I am using GPS/navigation because the system can change screens, select different options, and interfere with the navigation information I am trying to view while driving. This creates a safety concern because the unexpected touchscreen activity is

Every component, by complaint count

The full breakdown of what owners named when they filed. Components below the top ten are grouped out of this table.

How other model years compare

The same nameplate across the years we hold. Complaint counts fall naturally for newer cars because fewer of them have been on the road for long, so read the column as a rough signal rather than a ranking. In this set the 2018 Honda Accord has drawn the most complaints and the 2021 Honda Accord the fewest.

What to check on the electrical system

Electrical reports cover a wide spread: screens that reboot, cameras that go black, charging that stops, and warning lights that arrive in groups. The common thread is that the fault comes and goes, which makes it hard to show a mechanic on demand.

Buying a used 2021 Accord

Sit in the car with the engine running and work through every switch, screen and camera before you talk about price. An intermittent fault that appears once during a ten minute check is likely to appear often once you own it.

If you already own one

Have the battery and charging system tested before replacing any module. A weak battery produces electrical faults that look like a dozen separate failures, and the test is free at most parts retailers.

• Test every screen, camera and switch before agreeing a price.
• Have the battery and alternator tested before replacing a module.
• Ask for stored fault codes, including the ones already cleared.
• Check whether the fault is covered by a software update.
