2018 Honda Accord Problems

2018 Honda Accord problems owners report most

2018 Honda Accord problems are documented in public: owners have filed 2,013 complaints with NHTSA, the earliest in 2017 and the most recent in 2026. Sorting those by the component the filer named puts the engine clearly first, at 584 of the 2,013 complaints, 29 per cent 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 29 per cent of everything filed on a car, the pattern is doing more than chance.

Against the 2017 car, this model year has drawn 244 per cent more complaints (2,013 against 585). The 2017 car was led by its electrical system instead, so the pattern shifted between the two years. A rise is worth more attention than a fall here, because a newer car has had fewer years on the road to accumulate reports.

Of those complaints, 38 describe a crash and 5 describe a fire. Filers reported 41 injuries.

Recalls on the 2018 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 6 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 engine, 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.

The vehicle is stalling while driving to a point where on the freeway it slows down to 10 miles per hour to all of the sudden have all the emergency lights on that come to a sudden stop. I have called 3 different Honda dealers, they said that they need to check what is wrong with the car first making it clear that there is a fee of $220. My daughter has been driving the vehicle in very unsafe conditions. On Friday [XXX] we were on our way to Oakland from the Ventura County (I was the passenger) and in less than an hour driving the car started stalling to come to a sudden stop on the freewa

I am writing to file a formal complaint regarding my 2018 Honda Accord [VIN# [XXX] ] concerning what I believe to be a defective cylinder head or head gasket — an issue I have since learned is widely reported within the Honda owner community and is currently the subject of active class action litigation. Beginning at approximately 89,000 miles, my vehicle began experiencing episodes of engine rumbling followed by sudden shutoff. These episodes occurred two to three times before I brought the vehicle to an authorized Honda dealership at approximately 99,000–105,000 miles for diagnosis. At the

2/24/2025 Safety Recall work performed at Honda Marin; change Fuel Pump per recall. 4/28/2025 I reported vehicle stalling/misfiring, decelerating on its own and all lights keep coming on as a result of Fuel Pump change. Marin Honda performed cleaning of battery cables; technician claims nothing is wrong with the car. [XXX] car stalled at intersection, I went back to Honda Marin and reported vehicle is still having the same previous issues and complained that this is dangerous to have the car automatically decelerated on its own.

I purchased my vehicle from Lithia, Inc. d/b/a Wilde Honda in Waukesha, Wisconsin new. Wilde Honda serviced the vehicle on [XXX], after I reported that all lights in the vehicle were coming on. In addition, I experienced an incident on the highway where my car failed to accelerate, putting me in extreme danger. On [XXX], after my vehicle was returned to me, I experienced substantially similar issues immediately, with the same problems accelerating, all of the dash lights coming on, and a rumbling and jittering sound when the vehicle was first started. Wild Honda charged me $4,956.36 for re

I am reporting a suspected head gasket/engine defect involving my 2018 Honda Accord Sport. My vehicle experienced multiple engine-related problems before ultimately requiring head gasket replacement and cylinder head repair. On July 27, 2024, at approximately 161,480 miles, the turbocharger was replaced. In September 2025, at 207,539 miles, my vehicle was serviced at Joe Morgan Honda, an authorized Honda dealership. During that visit, the Honda technician documented that the cooling system fluid level was low and that no external leaks were found. The technician documented that they suspect

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 engine

Engine reports range from oil consumption between services to rough running, stalling and a loss of power under acceleration. Oil use is the one owners notice latest, because nothing warns you until the level is already low.

Buying a used 2018 Accord

Ask for every service record and check the gap between oil changes against the level on the dipstick now. An engine using oil quietly is the most expensive fault on this list and the easiest one to miss on a test drive.

If you already own one

Start a log of oil level between services. A documented consumption rate is what turns a conversation with a dealer from an opinion into a claim, and some manufacturers have covered these repairs well past the warranty.

• Check the oil level and condition yourself before buying.
• Ask for service records covering every oil change.
• Record oil level between services to document consumption.
• Have a compression or leak down test done before a major repair.
