2019 Honda Accord Hybrid Engine Problems

“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. I turned it off, waited a moment, turned it back on. It seemed ok so I drove carefully using back streets to the local Honda dealership. They kept the car for 2 days and ran tests but nothing showed on their computer and they could not replicate the problem. …”

“Shortly after starting the car, car shudders when accellerating over 40 MPH. Do not matter which mode it is in. All lead to engine shuddering and the flashing check engine light. When not engaged in eco mode, I received a notice say canceling econ mode when the mode was not egaged, the typical process is start car and within a few minutes, accelerate above 40 MPH and within seconds get a blinking check engine light, a shuddering engine that is slowing down below 60 mpg and getting more violent, this began after picking up the car from having routine maintenance performed. …”

“Component that failed was the head gasket. Willing to have vehicle inspected. However this incident occurred roughly 7 months ago at 125k miles. Safety was put at risk due to engine overheating which could've caused a fire. I haven't asked the dealer if they've seen it before however this issue is easy to find on forums for this vehicle. The vehicle was only inspected by the dealer who repaired it, I was told by them they had to send off some part of my engine to honda to ensure it wasn't warped before repairing. …”

“I was driving on the freeway and my engine lost power and all the lights on my dashboard went haywire. I tried to get off the freeway but with the loss of power made it extremely difficult and dangerous. I thought I was going to get into an accident since my car slowed down so abruptly. I had to limp my way across traffic which was very scary. The car was jerking and shaking. I finally got to the side of the freeway and the car did not want to continue so I called for a tow truck and waited on the side of a busy highway. …”
