In owners’ own words
Source: NHTSA complaint databaseFiled with NHTSA by the people who own these cars, about the engine. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.
On January 22, 2025, I was driving at highway speed and suddenly my car seemed to lag in power. It slowed from about 60mph to 40mph and pressing on the gas did not do anything. The Check Engine light began flashing. I felt like it would continue to slow down and it was rush hour. I managed to safely exit the freeway and parked the car.
Engine light came on. First time this has happened. Took car immediately to Honda Dealer for inspection of engine light. Was informed that the car had a blown head gasket. Car only had 116000 miles. Car was taken to same dealer where purchased, and serviced constantly. Not once were we notified of any issue with the engine
The head gasket on the engine has blown at only 94,000 miles. Car overheated on the side of the freeway and I took it to the dealership. Dealer confirmed that the head gasket was leaking. Check engine light and a temp warning came on as the car overheated
Head Gasket developed holes at 70,000 miles despite all recommended maintenance completed. This can cause serious engine damage which can lead to multiple safety issues
On 6/14/22 and 3/29/23, my 2019 Honda Accord EX Hybrid had engine misfirings which lead to total loss of power on Rt 15 in NY and CT: 6/14/22: Upon entering highway, car bucked during acceleration and lost all propulsion coasting to a stop. Check again light was on and blinking.

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre engine problems common on the 2019 Honda Accord?
They are documented: NHTSA holds 220 owner complaints naming the engine on this model year (28% of everything owners filed about it), and 81 manufacturer bulletins are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the engine on the 2019 Honda Accord?
No recall campaign is filed under this heading for this model year (there are 6 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do engine problems show up on the 2019 Honda Accord?
Owners who gave an odometer reading reported it at a median of 79,000 miles; half of them between 10,000 and 108,000. That is when reports cluster, not the life of a part.
What does NHTSA's "Engine" heading cover?
The engine and its cooling system. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
