Overheating on other Accord years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2016, 2017, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
Most owners in this group notice the coolant before they notice the heat: a reservoir that keeps dropping, a sweet smell, or a bright puddle under the front of the car. Across the vehicles on this site, about four in five of these complaints mention coolant, a leak or a puddle, and roughly two in five mention the temperature gauge or overheating.
What got replaced
Owners who name the part that was replaced mention the head gasket (92 reports), the radiator (3 reports) and the coolant hose or reservoir (3 reports).

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2019 Honda Accord that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.
Under certain conditions, the cylinder head gasket effectiveness may be reduced which may cause vehicles to experience overheating, coolant loss, misfire and/or DTCs P0300 thru P0304 stored.
What owners wrote
“Vehicle started sputtering, then all the engine lights came on. The car felt like it did not want to drive. Took it to the dealer for diagnosis. Dealer reported that the head gasket needed to be replaced. He stated that this is a known issue but that Honda has not issued a recall. The car only has $100,000 miles. Dealer said to call American Honda to see if they would give any "good will" money. They declined.”

Should you keep driving it?
This page can't tell you that. 1 of 99 reports involved a crash and 2 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
