2021 HONDA ACCORD HYBRID Complaints

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.

I just got off the freeway and coasted down the off-ramp, did not engage the brake nor the acceleration pedals. Suddenly the emergency brake system slammed on the brakes, it slowed me down from about 50 mph to around 20mph. There were no vehicles in front of me for at least 100 yards. It almost caused an accident by the people who almost slammed into the back of me.

My car has 79700 miles and starter shaking vigorously while on the freeway. Took it to the Honda dealership and I have a blown headgasket. After reading the [XXX] forums this is a ridiculously common problem with these cars around 45-90k miles. Honda is saying it's not under warranty and it's a $5400 fix for me. With so many cars with the same 10th generation engine having blown head gaskets below 100k miles this is an problem and a safety issue. Honda needs to fix these issues for their consumers.

At 14,000 miles the passenger front seat shifts laterally when occupied under weight shifts in turns. Also makes an audible knocking sound. American Honda would not cover this potential safety issue after positive diagnosis from our local Honda dealer. The vehicle is covered under a 12,000 mile CPO warranty.

The brakes locked when car is backing. I'm scared the brakes may fail on me. The brakes makes a lot noise when backing from the first year the car was purchased.

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.

My daughter was driving the vehicle on the highway, probably 65 mph. she said that a sheet shaped piece of metal struck the front bumper. It is not clear if this was on the road or fell from the car. It seems to have happened fast. the vehicle sustained no obvious body damage but the frame and bracket holding the milliwave radar module were damaged. The milliwave module was intact. the cover for the milliware radar module was missing. This car has not been in a collision. The dealer wants over $2,000 to replace all the components including the milliwave radar. They say it is probably broken. If the existing module is reinstalled, they say it may not work. I was not able to download the estimate for repair. Does this happen often or is there a design defect?
