My vehicle is a 2018 Honda Accord Hybrid with 12,075 miles on the odometer. I was driving to work in the morning of 09/22/2021. The condition was dry and the outside temperature was around 60 degrees. I was merging onto the interstate in sport mode when all-of-the-sudden my car went into a limp mode. The check engine light began flashing and car lost 90% of its power. The engine made a knocking noise and began to shudder violently. I tried to switch it out of sport mode to get it back into Eco but the message displayed on the dash said something like "Unavailable at this time." I was about a mile and a half away from work and was able to creep along the road to make it there as it was losing more and more power. When I got to work (with the engine still running) I lifted the hood and the engine was still shaking hard. I scheduled an appointment with the local dealership to have it looked at that afternoon at 2:00 pm. When I drove it to the dealership 3 miles away, the check engine light was no longer flashing and the engine seemed to run fine. When I called the service advisor later that afternoon to check the status of my car he told me, "The technician drove the car around with the scan tool plugged into it and it drove fine. He wasn't able to pull any codes from the PCM." I find it to be odd. In my experience, whenever the CEL illuminates, a malfunction code will be stored in the PCM until it is cleared. Why would Honda program the PCM to reset and hide the malfunction code so that we're not able to diagnose the issue? I did take the car into the dealership earlier this year to get a warranty battery replacement and to perform 2 recalls (one was an emission recall and the other was for the BCM).

DRIVING SOUTHBOUND ON 101 SOUTH ON SUNNY CLEAR DAY 65 DEGREES WITH ALMOST FULL FUEL TANK AND 2 BATTERY BARS (ALMOST EMPTY) AND CLIMBING UP INCLINE ON 7 DEGREE GRADE AND CHECK ENGINE LIGHT WENT ON AND LOST ALL POWER AND CAR COMPLETELY SLOWED DOWN TO A STOP (LUCKILY WAS ABLE TO PULL OVER WITH NO PROBLEM).

THE VEHICLE MAKES A DRONE LIKE HUMMING NOISE. DEALER SAYS THEY ARE UNABLE TO DUPLICATE AND I SHOULD REPORT THE PROBLEM TO HONDA. NOISE HAPPENS INTERMITTENTLY WHEN DRIVING CAR AT ALL SPEEDS.

HONDA ACCORD HYBRID 2018 WITH 7439 MILES. I WAS DRIVING ON THE HIGHWAY BACK HOME FROM WORK . SUDDENLY CAR STARTS TO FLUSH MESSAGES THAT ALL CAR SYSTEMS FAILS AND IT NEEDS TO BE TOWED TO DEALERSHIP IMMEDIATELY. CAR STOPPED TO RESPONSE TO CONTROLS INCLUDING ACCELERATION AND STARTS TO SLOWS DOWN FROM 70 MPH TO 25 MPH. AT THAT TIME I REALIZED THAT THE ONLY OPTION WOULD BE TO PULL OVER ON THE SHOULDER. I DID IT TO BE ABLE TO STAY AWAY FROM TRAFFIC AND CALL EMERGENCY SERVICE. AFTER APPROXIMATELY 75 MINUTES I WAS TOWED AWAY TO NEARBY DEALERSHIP (MANCHESTER HONDA, CT). AS OF THIS MORNING I DON'T HAVE ANY INFORMATION FROM THEM. I WAS TOTALLY SHOCKED ON CAR BEHAVIOR AND THINK THIS IS NOT ACCEPTABLE FOR CAR WITH 7439 MILES AND ONLY 7 MONTH OLD.
