My 2020 Honda Civic experienced engine overheating and a cylinder 3 misfire (P0303). Two independent mechanics diagnosed a blown head gasket with coolant leaking into cylinder 3. The vehicle underwent a head gasket repair under Honda’s extended warranty. Less than a week after the repair, the engine overheated again while I was driving. I pulled over, waited approximately an hour for the engine to cool, added coolant, and drove to the dealership. The dealership later reported that the cylinder head was cracked near cylinder 4, close to the exhaust valve. When I picked my car up from the dealership, I scanned the vehicle and found the P0303 cylinder 3 misfire code. I am concerned that the engine may have an unresolved problem that could cause it to overheat again, sustain further damage, or lose power while driving. The vehicle is still in my possession and available for inspection. I have an appointment with an independent mechanic on October 24, 2026, to have the engine and cooling system inspected and determine what may have caused the repeated overheating. I am submitting this complaint to bring attention to a potential engine or engine-cooling safety defect and ask the federal safety agency to consider whether similar problems may be affecting other vehicles.

Sudden loss of power by model year
What owners say
I received notice of the recall for my car more than six months ago, and since then, I have been trying to schedule an appointment at the Honda dealership in Paramus, NJ. However, they always tell me that the replacement part is unavailable and that they will call me back. It has now been at least six months, and my car is losing power and consuming more fuel than usual. For my safety and the safety of others, I request that this issue be resolved as soon as possible. Thank you.
Once again while driving on the interstate at highway speed the car lost power and then died. At first it wouldn’t start and then finally did where it could be slowly driven to an exit for safety. I 100% think this vehicle needs included in the fuel pump recall! This is probably the 30th time it has done this. This is my 19 year old daughter’s car and it is very unsafe. We bought a Honda because we heard they are very good and safe and reliable cars. This hasn’t proven to be that! We can’t afford to just get another car or pay to have it fixed. I know there are many other Hondas with this recall in effect! Add this VIN number. I have reported this issue multiple times! Do better Honda and fix my daughters car before she gets in an accident that could injure or even kill her!
Today while driving at highway speeds of 75MPH my car once again lost power. The RPM’s go up and the speed keeps decreasing. I had to pull over on the interstate and shut my car off and turn it back on after awhile to get it to run again. I 100% feel that this issue is related to the fuel pump recall and this vehicle needs to be added to that list. It is a danger to be driving on the Interstate and lose power like that. One of these times someone is going to hit me on the side of the road. This is about the 20th time or more this has happened to me.
I was driving on 4/24/23 going 75 MPH. The car made a rev up noise and be RPM’s suddenly increased and the speed was decreasing. The car was losing power. I had to pull over to the side of the road and shut the car off and let it sit for awhile. The. When I started it back up it ran fine. This is a safety issue as I had to pull over on the highway and sit on the shoulder and could have been hit. No lights came on the dash at this time.
Clutch went out at 25k miles - never stalled this car. Have several manual transmission Hondas no problems except this one. Lost engine power and had to pull over on the highway. manufacturer error causing pre mature burnt clutch. This should not be happening. Honda will not take responsibility
