NHTSA Complaint #11701087 — 2021 HONDA CR-V

I am experiencing the problems that are described in investigation NHTSA CAMPAIGN NUMBER: PE25016. When driving on the highway, there have been multiple times (8-10) when the car stops accelerating and the check engine light starts flashing. I am not able to accelerate the car. If it turn the car off for 5-10 minutes, the check engine light stops flashing and I am able to drive the car again. It has always happened when I haven't driven the car for a while (either driving it for the first time for the day or after sitting idle at work for 8 hours), the problem happens within minutes of getting on the highway. I have taken the car to the dealership for service twice with this problem. The first time was in late August. They said there was no code with the check engine light and they could not replicate or find a problem. The most recent time was this past Friday (Nov. 21, 2025). I experienced the problem and immediately took it to the dealership. Because the check engine light was flashing, they were able to pull diagnostics and retrieve a code. They said a fuel check showed cloudy fuel and a spark plug was brown to copper color. They removed the old fuel and replaced all four spark plugs. This did not fix the problem, as I experienced it again this morning (Sunday, Nov. 23).
