2019 Honda Accord: engine overheating

Filed Oct 13, 2026 · Electrical, Engine · TX

Air conditioning failure: The A/C was blowing warm air on the first day of ownership. • Cooling system failure: The vehicle subsequently experienced overheating issues and left me stranded. • Coolant loss and radiator leak: All Star Honda identified a leaking radiator and found the cooling system out of coolant. • Failed thermostat: A failed thermostat was identified during the diagnostic and repair process. • Stop-leak substance found in the cooling system: Stop-leak material was observed in the cooling system. I have concerns about why it was present and not disclosed initially • Water pump and cooling-system repairs: Repairs included work on the thermostat and water pump, followed by radiator replacement and a coolant flush. • Continued overheating concerns: Despite repairs, I continued experiencing overheating alerts. • Engine performance problems: The vehicle experienced a loss of power, with a reported inability to maintain speeds above approximately 60 mph during one incident. • Check-engine warning: A prior repair-order history documented a blinking malfunction indicator light during a driving incident. • Diagnostic trouble codes: Codes P2601 and P272D were subsequently reported. • Potential head-gasket concerns: The possibility of a head-gasket problem has been raised during the ongoing dispute. Honda has referenced a multi-model cylinder-head-gasket warranty extension, but I have not received approval for coverage on my vehicle. • Warranty denial: Honda corporate has declined to approve the requested warranty coverage. Despite the repeated problems, diagnostic visits, and repair attempts, I am still dealing with the consequences of purchasing a vehicle that has not provided the reliable transportation I paid for. I have spent time and money trying to get answers, and I have been left facing the financial burden of a vehicle that I cannot confidently depend on. I am sharing this timeline because consumers deserve trans

The engine continues to overheat and shut down while driving. The engine often goes into "limp" mode while driving. The entire set of gauges and lights on the dashboard light up like a Christmas tree, alerting me that all systems in the car are malfunctioning. I fear that I may have a malfunctioning head gasket. I've replace injectors, radar sensors, new turbo, gas pedal, etc and I have spent nearly $10,000 dollars and MANY, many hours at multiple Honda dealers, across various different states. This car is a lemon and I am upside down on the value of the car and what I still have financed. I wish Honda would take responsibility for their new turbo driven CVT engines that are failing.

Head gasket needed to be replaced. Coolant leaking into cylinders, sudden loss of motive power / engine misfires while driving. Driving on the highway, and trying to accelerate, there is a hesitation and vibration and also when letting off the gas.

I was driving on the highway in Michigan, the speed limit is 70 mph. All of a sudden, I noticed that my car acceleration was not working. It ended up my engine misfired and in doing so, I could not go more than 20 mph on the actual highway!!! it was absolutely terrifying, even when I put on my emergency lights, I had to find a place to safely pull aside. I still had to pull out in front of someone to try to get off the exit, so pulling out in front of someone at 20 mph on the highway was petrifying. Once, I finally was able to pull into a safe place. I immediately called my insurance company and Honda about the misfiring of my engine. My car was then towed to a Honda dealership, where technicians diagnosed a blown head gasket caused by coolant leaking into a cylinder. The only warning light was the “check engine” flashing light when I was unable to drive more than 20 mph. My vehicle went limp. The repair required replacement of the head gasket at significant personal expense About $6k +.

My car began to not turn on. Took it to the dealership, was told it was the turbocharge being loose. They saw coolant leaking. Paid for the fix. Few days later, car lost power and entered lint mode. Took it back and with simple camera work they check the gasket was leaking. Told that since the turbo before wasn’t working as intended, the gasket became thin. Repairs are above 6k, had no warning lights. Seems this is a common issue.

The contact owns a 2019 Honda Accord. The contact stated that on several occasions while driving at undisclosed speeds, the vehicle started shaking abnormally. Occasionally, while depressing the accelerator pedal, the vehicle jerked hard. Additionally, the contact stated that the message "Emissions System Failure," "Engine Overheating - Turn off Immediately," and other unknown messages were displayed, with several unknown warning lights illuminated. The vehicle was taken to an affiliate dealer where it was diagnosed and determined that the head gasket needed to be replaced, and the engine needed to be disassembled to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

The head gasket has failed and Honda knows this is an issue. There is a lawsuit in California about the head gasket failing. With it failing the whole engine is at risk for being ruined. This is going to cost $4000-$10,000 for people to fix depending on the damage it causes the engine. I personally lost acceleration on the freeway while going up a hill and everyone around me going 65-80 mph. I have 11 warning lights on my car right now and it started overheating today with a warning stating that the engine was hot and to stop driving immediately. We had to get towed to the mechanic for the 2nd time this week. When searching online I realized this was a known issue and about the class action lawsuit.

The vehicle's head gasket failed prematurely, resulting in coolant intrusion into the engine cylinders and combustion chamber. This caused the engine to unexpectedly overheat while driving at highway speeds, creating a severe safety hazard and loss of acceleration in active traffic. Additionally, it had a very rough idle when starting.

On April 14th, 2026 we were driving on the road, the car overheated. We shut it off, sat for a few minutes. Started driving again and had to sit in roadwork, within 1 minute the car started to overheat again. We pulled into the gas station, checked coolant levels, all fine. We let the car sit for 20 minutes or so, we tried to turn the car on and the engine started sputtering and all dash lights came on. We got the car towed to a shop, they looked over the car and told us that coolant had leaked into the cylinders and the head gasket was blown but there was no leak in any of the coolant areas. They quoted us over $7000. So we are out of a car while it’s at the shop waiting to get fixed.

My car started getting hot, began to overheat. I was on my way home on freeway. Second lane from slow lane. My car began to loose power, I could no longer excelerate. There was a big rig coming up behind me he was not slowing down as he got closer began honking I was trying to flag him that I could not move, as I was trying it started to go like 5 miles per hour where i began slowly to get over, cars in the other lane slowed down. Big rig went around me and avoided any collision. Thank God. I slowly made my way home on the streets with heater blasting. I towed my car to the dealer. I was told, my head gasket needed to be replaced, more than likely I would need a knew engine. Dealership said it was because when taken my car in for service I did not bring to the dealership. Cashier told me that there have been several incidents as mine.To my surprise I googled 2019 Honda Accord engine, and there were many with the same issue same car same year. Yet no recalls! I was lucky not to have been killed or have caused a multiple car collision. Are we waiting for someone to be killed to recall these engines. I missed several days of work, borrowed cars and rented a car to get back and forth to work not to mention the tramatic experience of a big rig coming at you honking on a FREEWAY. A week prior to this incident, my lights on the dashboard came on. I did call the dealership to set up an appointment. At that point they were no signs of overheating. I have taken my care in faithfully for oil changes where all fluids are checked, i was not told not once that any fluids were ever low, last visit was approx 5 months ago. I have called to have them send me all receipts. However in hindsight I do not need theses records as it has been proven by other people they have had the same experience. We are not talking about a faulty air conditioner we are speaking of an engine, in my case power failure. In the even records of oil changes and dealership diagnosis is required. I can email.

My 17 year old drives this car and has suddenly stalled and gone into limp mode 3 separate times (twice on busy highway) with no warning or codes provided. Most recently the vehicle alerted of overheating. After a couple trips to mechanic it was determined that head gasket is going out. It seems that this is a very common problem with this vehicle and an extreme safety hazard. Especially with young drivers as it sent my daughter into panic and nearly caused accident on initial breakdown.

Head gasket failure was diagnosed by a certified dealer. The only symptom leading up to the failure was slight hesitation when starting the vehicle. Safety issues include sudden engine power loss, engine fire, overheating, and reduced visibility from thick white smoke, and the potential loss of steering or braking power.
