2020 Honda CR-V: misfire or rough idle

Filed Oct 31, 2026 · Acceleration, Electrical · NY

I am filing this complaint regarding a recurring and dangerous loss of engine power in my 2020 Honda CR-V, currently at approximately 80,000 miles. For an extended period, my vehicle has repeatedly experienced multiple dashboard warning lights illuminating simultaneously, followed by severe loss of acceleration. During these episodes, the vehicle enters a reduced-power state and can only travel approximately 10 mph. This creates a serious safety hazard, especially on highways and in heavy traffic, where sudden loss of acceleration could cause a collision. I have taken my vehicle to independent mechanics numerous times for these same issues, but the problem has never been permanently resolved. During one evaluation, a mechanic identified engine-related diagnostic information and showed me Honda Technical Service Bulletin 18-025, concerning misfires and air-fuel imbalance. I subsequently brought my vehicle to Atlantic Honda in [XXX], where their technician diagnosed faulty fuel injectors and quoted $1,800 for replacement. Both Atlantic Honda and Honda Corporate denied warranty or goodwill assistance, stating that my vehicle exceeded the 70,000-mile eligibility limit by approximately 10,000 miles. On XXX, my vehicle again experienced severe power loss in [XXX], limiting acceleration to approximately 10 mph. I was unable to safely continue driving and had to leave my vehicle in [XXX], where it now requires towing. This is not an isolated incident but a recurring problem that has persisted despite multiple visits to mechanics. I am concerned that faulty fuel injectors may represent a broader safety defect affecting other 2020 Honda CR-V vehicles. I respectfully request that the federal safety agency investigate these repeated failures and determine whether additional vehicles should be included in any applicable safety recall or corrective action.

When driving on highway, the engine light came on and the car suddenly slowed down causing me concern about traffic around me still going at highway speed. Not understanding what the issue was and afraid the car would lose all power, I was able to shift lanes quickly to get to the breakdown lane. I was able to get the car to Honda Dealer driving at slow speed using back roads. The Honda Dealer confirmed an engine misfire caused the engine light and slowdown. The cause of the misfire was coolant leaking into engine cylinder and would require replacing the head gasket to fix the problem. The car had 75,000 miles and had been running fine until that point.

At approximately 75,000 miles, my 2020 Honda CR-V began experiencing serious engine performance issues, including jerking, hesitation, and rough operation while driving. The check engine warning light began flashing, indicating an active engine misfire. During these events, the vehicle’s acceleration and engine response became unpredictable. Only traveling at 5 mph. The ignition coils and spark plugs were replaced, and then replaced again, by an independent mechanic. After the most recent repair, the vehicle was test driven and the issue persisted. A diagnostic scan shows the engine is running rich, which mechanics stated points to a fuel injector malfunction. Based on diagnostic results, repeated test drives, and elimination of ignition components as the cause, the fuel injector system is the component believed to have failed. This malfunction poses a safety risk because a misfiring engine can cause sudden loss of power, hesitation during acceleration, and unpredictable vehicle behavior, especially during merging, passing, or driving in traffic. The issue has been reproduced and reviewed by multiple mechanics, who reached the same conclusion regarding a fuel injector related failure. Prior to and during the failure, the vehicle exhibited jerking, hesitation, rough operation, and a flashing check engine light. These symptoms have continued despite repairs. The fuel injector failure is the subject of an active recall affecting this make, model, and year, however my VIN is not included in the recall. Despite this exclusion, my vehicle is exhibiting the same symptoms, misfire behavior, and diagnostic indicators addressed by the recall. The exact reason my VIN is excluded from the recall is unknown, but the evidence indicates a fuel injector related defect affecting safe operation of the vehicle.

This past year, on 10 occasions, the car misfires and loses power. All but 1 of these occurrences have been on the highway. The check engine light blinks, I pull over, turn the car off, wait a couple minutes, start the car, and the problem disappears. I have had the codes checked by both Honda and my personal mechanic - and neither can find a code that anything is wrong with the car. I have replaced the battery and 4 spark plugs but the issue keeps happening - more so recently as the weather is a little colder now. I am submitting the date of the most recent occurrence - but this has been happening since January of 2025.
