2021 Honda Accord Hybrid Engine Problems

“2021 Accord Hybrid Touring 2.0L with 51k miles. On 10/22/2023 the check engine light started flashing so I pulled over and noticed the engine was running rough so I shut it off. When I restarted it all was fine, no CEL, so I drove it to the dealership. They stated that there are no CEL codes found, so come pick it up. I told them that the CEL flashing was a major problem and I pulled a P0304 code. 2 days later they called and told me it had blow head gasket.”

“I purchased my vehicle in March 25th 2024 a message on my dashboard saying engine is too hot so in August of this year I took it to the shop for a diagnosis test and they told me that the car didn’t run hot when they drove it so again in October 10th I was driving home and my car lost power on the freeway so I pulled over and then all my lights on the dashboard came on so I took it to the shop on October 13th and they told me that my head gasket was faulty and my coolant system was faulty. …”

“My vehicle is currently suffering a failed head gasket. I was alerted about this issue from local mechanics and friends way before it actually happened. I took it to services and regular maintenance even more frequently after that. However, it still failed no matter what. I took it to the dealership, they even admitted that this is a known problem for this generation of vehicle. They still proceeded to ask nearly $7000 to fix it, saying that even though this is a known issue, there was no recalls on the vehicles so they could not waive or deduct the fees.”

“On 4 separate occasions, the first on December 22, 2022, my Accord began losing power and acceleration while driving on the highway. The engine light began flashing but never came on steadily, and no message displayed. On a couple of occasions it was raining a bit, and at other times the weather was dry. Each time, I pulled the car over to the side of the road; before turning off the engine, I noticed the engine was loud and the car was shaking a bit. After a minute, I turned the car on and it operated normally, with no flashing engine light. …”

“Twice while driving at highway speeds the check engine light came on. My car's engine was misfiring, and I have no acceleration. Both times, I took local roads home on which I could drive below 35 mph. Pulling out from traffic lights and stop signs was difficult. The dealership where I bought the car has been unable to diagnose the problem. No codes come up on the computer, and my car is currently at the dealership. The service manager has been able to duplicate the problem and still no diagnostic codes were recorded. The dealership technicians have contacted Honda engineering for advice.”
