Owners have filed 140 complaints
about the 2019 Honda Accord Hybrid with NHTSA between 2019 and 2026.
The largest single group is the driver assist & collision avoidance.
Across this model's run it ranks 5 of 12 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 71
Against the median year of the Honda Accord Hybrid. 50 means typical for this
model; 100 means roughly double.
Severity — 29
5.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
78% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
How 2019 compares with every other Honda Accord Hybrid
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

When owners complained
A spike years after the car went on sale usually means a part wearing

owner can see from inside their own car.

NHTSA investigations into the 2019 Honda Accord Hybrid
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.
On February 21, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE22003) to assess reports of inadvertent activation of the Collision Mitigation Braking System (CMBS), an automatic emergency braking (AEB) system, in model year 2017-2019 Honda CR-V and 2018-2019 Honda Accord vehicles. The reports allege that activation of the AEB system occurs while driving with no apparent obstruction in the vehicle's forward path, resulting in sudden vehicle deceleration. Honda indicated that they were aware of a total of X,XXX reports that may relate to the alleged defect. Hon...

The standard became fully applicable to all such vehicles manufactured on or after Marc...
Recalls on the 2019 Honda Accord Hybrid
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

ON DECEMBER 26, 2020, I WAS LEAVING WORK, AFTER A 12 HOUR SHIFT AT THE HOSPITAL. WHILE BACKING INTO AN ALLEYWAY MY CAR STRUCK A LARGE ROLL-OFF DUMPSTER (WHICH WAS CADDY CORNERED IN THE ALLEY) OF THE BACK, DRIVER QUARTER PANEL AND BACK DRIVER DOOR. THE REARVIEW CAMERA, BLIND SPOT WARNING, PARKING COLLISION WARNING, THE REAR CROSS TRAFFIC WARNING, NOR THE AUTOMATIC EMERGENCY BRAKING KICKED IN.

I HAVE NOTICED THAT I HAVE ALSO HAD ISSUES WITH MY LANE DEPARTURE WARNING AND THE FORWARD COLLISION WARNING HAS BEEN NOT WORKING 100% OF THE TIME RECENTLY, BUT THAT NEVER BOTHERED ME BEFORE.

Head gasket blown on engine. Burned off coolant so no leaks detected and just showed high temperature to pull over and let engine cool. Could have cause engine fire and/or disabled vehicle while on road. Very expensive fix and dealers who were contacted said they’ve had multiple vehicles repaired for same issue. Online is widely reported problem with this make and model and among the different trim types all same problems

Vehicle was being driven on the highway when suddenly engine hesitated and started stalling. Speed was reduced from around 65MPH down to the low 40s. Cars were stacking up behind and passing, causing potential hazardous conditions. Vehicle was taken to a mechanic shop and diagnosed with misfiring, after reading OBD II with many alerts coming on. Further diagnostics revealed cylinder head gasket was leaking coolant into engine, as shown by borescope images. This is a known problem on 2018-2020 Honda Accords with both 1.5T & 2.0 engines. The multiple alert messages started to come on a few weeks ago, but the engine hesitation and stalling just started this week. At first we suspected a 12V battery issue, but testing confirmed battery was at 12.8V with no issues.

VEHICLE SPEED CONTROL
1. Component: The engine head gasket and the combustion system (specifically Cylinder 2). Specifics: A leak-down test confirmed a failure in Cylinder 2, leading to coolant intrusion. This was initially masked by a water pump code, but after the water pump was replaced and the code returned, a borescope confirmed "clean" pistons (steam-cleaned by coolant) and tap scarring. Availability: Yes, the vehicle and all diagnostic records are available for inspection. 2. Emergency Maneuvers: On multiple occasions, the car entered "Limp Mode" while driving 70–75 mph on the freeway. This caused a sudden, dangerous drop in speed, forcing me to maneuver through high-speed traffic to reach the median/suicide lane. Stranded: The vehicle overheated 5 times in one trip, leaving me vulnerable on the side of a busy freeway. 3. Yes. An independent shop confirmed the failure via a leak-down test, a borescope inspection, and physical analysis of the spark plugs. They confirmed that despite the computer throwing a water pump code, the mechanical failure is the head gasket. 4.Status: It has been inspected by an independent service center. I am now using their findings to pursue a lawsuit/claim against Honda for selling a vehicle with a pre-existing internal engine defect. 5. Timeline: Symptoms began in April 2024 (two months after purchase). Initial Signs: An "Emission System" warning light appeared. The diagnostic code indicated a water pump failure, which was replaced in April. Recurring Symptoms: In November, the car suffered multiple misfires and "Limp Mode." In March, the "Emission System" light and the same water pump code returned, but the shop confirmed the pump was functional and the true cause was the head gasket leak into the cylinders.

Description of Incident: 1. Component/System Failure: The engine cooling system and head gasket failed. A certified shop has confirmed coolant intrusion and a failed leak-down test on Cylinder 2. The vehicle is available for inspection upon request. 2. Safety Risk: My safety and the safety of my family and other drivers were put at extreme risk. On March 1, 2026, the vehicle suffered a sudden loss of motive power while traveling at 70 MPH on the freeway. The car dropped to 15 MPH instantly, forcing me to maneuver across active lanes to a narrow shoulder with almost no space. I was nearly hit by high-speed traffic. This has occurred over 8 times since 2023. 3. Confirmation by Service Center: The problem has been reproduced and confirmed by an independent service center On Site Lube Auto & Tire. They utilized a borescope and leak-down test to verify the internal engine failure. 4. Inspections: The vehicle has been inspected by a certified independent technician. I am in the process of notifying the manufacturer (Honda) of these findings for their inspection and accountability. 5. Warning Lamps & Symptoms: Prior to the total power loss, the vehicle displayed engine temperature warnings and "check engine" lights. These symptoms first appeared approximately 8 months after purchase in 2023 and have progressively worsened, leading to the current engine failure. 6. Additional Notes: This failure is identical to issues cited in active class-action lawsuits regarding Honda's engine defects, affecting both standard and Hybrid models. I am communicating via written report/email for documentation and accessibility purposes.

Warning Lamps & Symptoms: Prior to the total power loss, the vehicle displayed engine temperature warnings and "check engine" lights. These symptoms first appeared approximately 8 months after purchase in 2023 and have progressively worsened, leading to the current engine failure. 6. Additional Notes: This failure is identical to issues cited in active class-action lawsuits regarding Honda's engine defects, affecting both standard and Hybrid models. I am communicating via written report/email for documentation and accessibility purposes.

POWER TRAIN
City street driving speed < 35-40 mph, engine began rough idling at stop light after traveling just 1/8 mile. After driving less than 1 mile on level ground, engine slowed and would not accelerate above 20 mph. After another mile or so, increasing uphill grade caused speed to slow to 12-14 mph. Stepping on gas caused car to slow down even more, with shaking and jerky stop-start of vehicle. Maintaining 10-12 mph permitted vehicle to continue uphill climb for a few more miles so I could reach home. Downhill coasting was smooth with no gas pedal acceleration. Overnight parked in garage, and no problems driving vehicle to local independent auto mechanic. They were able to duplicate problem after 2 days and multiple test drives. Diagnosed permanent and temporary engine codes: misfires of cylinders 1 and 4 with ignition coil malfunction, misfires of cylinders 1, 2, 4, and random misfires. Also permanent codes: antilock brake ECM Failure, electric power steering vehicle stability assist System Malfunction, electric servo brake electric power train System Malfunction. Mechanic removed coils and spark plugs, found cylinder 4 has moisture. Coils, plugs cleaned and re-installed. Honda Dealer unable to duplicate problem after 3 days.

STRUCTURE:BODY
Paint is peeling on the roof along the sides in the grooves and in the groove between the back window and the body. This appears to be the exact same paint issue that was reported on the 2018 Honda Accord models made at this plant. I just noticed this today (9/19/25) but given the rust, this has probably been a problem for longer.

ENGINE
It appears the head gasket failed due to an anomaly on the engine block between cylinders. We were driving down the road when the engine lost power and went into limp mode ( dealer term). The problem of the head gasket was confirmed by the dealer, but the anomaly on the short block has not been explained. The engine block was inspected by the service tech, service manager and a rep from Honda. No explanation given. No warning lights came on until immediately after the engine lost power. The engine block is available for inspection at the dealership.

FORWARD COLLISION AVOIDANCE: WARNINGS
While traveling at approximately 55 mph yesterday, in daylight, with no other cars in front, back, or to the side of our car, it radically braked on its own. The collision mitigation system warning light has frequently flashed on the dashboard since we bought the car new in 2019 but never did it apply the brakes on its own. Dealerships over the years have told us "this just happens", and offered no fix for the false positive alerts. This is a dangerous situation which could result in an accident or even death of occupants if not resolved by Honda. I spoke with several dealerships since the phantom braking event and they tell me they hear this complaint often. Being an intermittent situation, it is extremely difficult to diagnose and resolve. Something needs to be done.

Component or System Failed: The head gasket appears to have failed, leading to coolant leaking into cylinder 4. This has been confirmed by two separate service centers. The vehicle is currently available for inspection if needed. Safety Risk: The failure caused engine misfires and dashboard warning lights to activate while driving, which could have led to a sudden loss of power or control. I had to pull over and restart the vehicle to regain drivability, which put my safety and that of others at risk. Reproduced or Confirmed by a Dealer or Service Center: Yes. The issue was first diagnosed by Honda of Sumner, who initially suspected a compression issue. Their master mechanic later confirmed it was likely a head gasket failure. A second opinion from Greg’s Japanese Auto confirmed the diagnosis and provided photos showing coolant in the cylinder. Inspected by Manufacturer or Others: Yes. The vehicle was inspected by Honda of Sumner and Greg’s Japanese Auto. No inspection has been done by police or insurance representatives. Warning Lamps or Symptoms Before Failure: Yes. After a recent service (which included an AC repair, fuel pump recall, and oil change), I experienced two misfires in cylinder 4 within 24 hours. All dashboard warning lights came on during one of the incidents. These symptoms began four days after the service. Additional Context: I was quoted $8,100 for the head gasket repair by Honda. I believe this issue could have been detected earlier during the diagnostic service. I’ve since learned of a class action lawsuit involving this exact issue in my vehicle’s generation, which makes me concerned this is a known defect.

FORWARD COLLISION AVOIDANCE: WARNINGS
All of sudden, no incident, no accident, a lot of things were disabled such as Adaptive Cruise Control , Forward Collision Warning , Lane Departure Warning and more while I was out of town (long range highway travel). When I went to Honda dealership, they blamed a few things and fixed them (expensive), then they said that the front camera needed a calibration. It was expensive. After that aiming correction, everything works fine. The camera was NOT broken. It just needed recalibration, and it costed about a thousand dollars. I would say it was caused by the poor design, which is Honda's fault. I googled this issue and found a lot of Honda owners had same issued and charged 1K ~2K for it. I will report it separately, but my Honda Odyssey has the exactly same issue now. I have 2 Honda cars, and both of them have the same issue. I strongly suggest that Honda should recall their front camera and they should reimburse the expense we already paid for it.

STEERING
I was driving on a city street at about 30mph. There was no one in front of me or behind me. Nothing in the road. The orange rectangular brake light came on for no reason, kept flashing and it felt as if the brakes were automatically being pumped, slowing the car down to a compete stop. In addition, I had no control of the steering. It was very dangerous situation which could have resulted in accident or injury.

Blown head gasket repaired after unknown coolant loss. Eventually intermittent warnings to pull over and slow down which resolved within seconds. Continued until it was determined the gasket had failed. Numerous instances of hybrid engines failing in this manner. Repaired by independent shop.
