“Once again the car loses ability to accelerate after driving at highway speeds and driving for about an hour. The car won’t accelerate and has to be turned off and has to sit for awhile. Sometimes the car struggles to start back up. This may happen several times when I drive. This is a safety issue as the car isn’t reliable and can’t just not accelerate on the highway. I feel this is related to the fuel pump recall and that my kind of civic needs to be included in this.”

“The turbocharger bypass control solenoid valve circuit on my 2020 Civic Si has developed an intermittent open, setting DTC P0035. I diagnosed it myself: the solenoid coil measures 45 ohms and functions when commanded via bi-directional scan tool, and supply voltage is present at the harness connector. However, the control circuit reads approximately 9V in the off state when it should be near ground, and the reading fluctuates when the harness is flexed near the connector — indicating a partial break in the wiring consistent with vibration fatigue. …”

“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. …”

“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.”
