2018 Honda CR-V: check engine light

Filed Nov 9, 2026 · Electrical · OR

Vehicle experiences persistent, simultaneous flashing of all dashboard warning lights (Check Engine, Braking System, Traction Control, Steering Assist). This issue blinds the driver from seeing real-time critical vehicle warnings and disables active safety features. Dealer diagnostics confirmed fault codes P0172 (Fuel System Rich) and P0303 (Cylinder 3 Misfire) caused by failing fuel injectors flooding the cylinders. This is a widespread defect on 2018 1.5L Turbo engines that poses an active driving hazard.

1. Head gasket leaking into engine, car is overheating now. Told it is a slow leak, not safe for long distance travel, need new car. 2. My car is available for inspection upon request. 3. I am a woman and could have been stranded by this in vulnerable situations. I am a travel worker driving to places like Maine and California and camp alone in remote areas. Starting to overheat has happened on 270 in Maryland during a traffic jam after I had the mechanic tell me I can drive locally as long as the coolant is kept full — which was done 2 days ago. 4. My mechanic looked at the car Friday, July 24th, 2026 and can confirm the failure. 5. My car started overheating this week when I was idling in Park with the AC on and the air started blowing warm air. I had overheating light one time and it was a flash. I thought I was out of Freon and needed it serviced. Now, If I put my car in park with the engine still on, the thermostat goes up. If I drive in a traffic jam where I am stopping and going, the thermostat goes up. The AC won’t work most of the time now. 5.1. A year ago my check engine light came on, turned it off, and sat for a half an hour. I called my mechanic and he said to bring it over if the light was off. I started the car and the light was off. He looked at it and said all the coolant had blown, replaced the coolant and said to drive locally for a while, that it might be that the thermostat got stuck and as a safety, the coolant blew out. No more problems. Same mechanic. I have been the sole owner of this car, I have taken very good care of it. I have the same mechanic do 95% of the work. I only have the oil changed at his place or trusted mechanics in other area I see online that this is a known issue for this year, make, and model — on Reddit and it was Chat GPT that was the first that let me know that this is showing up on different auto boards and in articles for 2017 - 2018 Honda CRVs that have Turbo engines with links to sources.

power and began running rough. The check engine light illuminated, and the vehicle did not perform normally. I previously had the vehicle diagnosed and repaired at a Honda dealership for this same issue. The repair was completed less than two months ago. After only a few thousand miles since the repair, the exact same symptoms returned, including the check engine light, rough engine operation, and loss of power while driving. The recurrence of this issue raises concerns about the reliability and safety of the vehicle, particularly when operating in traffic or at highway speeds, as sudden loss of power could increase the risk of a crash. The problem appears to be the same issue that was previously repaired, but it reoccurred shortly after the repair was completed.

Honda 2018 CRV VIN [XXX]. Car was brought to Honda dealer due to smoking issue from exhaust directly after fuel pump recall. Work was done at Napleton Honda that was under direction from America Honda to replace the head gasket for no engine codes were found and engine light was not on. CRV head gasket was replaced for $6,000 and still smoke was coming from exhaust. Returned the vehicle to Napleton Honda dealer and America Honda then claims issue is a Turbo issue and that is what is causing the smoking for another $5,500 they can swap that part too. I expect America Honda will recommend next the rear-view mirror will need to be replaced for that is how we are seeing the smoke from the exhaust. The Dealer is under direction from America Honda on what to replace and they have failed to fix the issue. Multiple websites reference that the recalled fuel pump is causing engine trouble like fuel gasket and turbo which America Honda knows for that is what they are recommend being replaced so far. If you do some discovery on this, you will also see there are several class-action lawsuits on this same issue in the US and several other countries.

The systems affected with failure notifications were Electric Parking Brake, TPMS, Emissions, Brake, Brake Hold, Power Steering, Vehicle Stability Assist, Hill Start Assist, Adaptive Cruise (including regular cruise), Collision Mitigation/Avoidance, Road Departure Mitigation. The stored codes in the vehicle that I was able to read were P0300, P0303, P0304. This failure bears a striking resemblance to that of TSB 21-010, directed at Keihin manufactured fuel injectors, PN: 16010-RLV-315, which was later replaced with updated ...-305 after the failure was determined, and the vehicles were given a 10 year 150,000 mile warranty. The CRV had injector PN: 16010-5PA-305, also manufactured by Keihin, which was also later revised to 06160-..., but the CRV was not given the same warranty extension, suggesting Honda acknowledged the same defect pattern across both injector families but chose not to extend equivalent coverage to the CRV. 21-010 also details that debris from the high pressure pump may contribute, and the CRV experienced the same fuel pump recall for low density impellers that these vehicles did. Honda is also obligated under TSB 98-081 to perform emissions services due to OBD inadequacy, which this vehicle experienced. Misfires were felt for months with no CEL. The Norm Reeves Honda parts catalog classifies injectors as emissions components, implying they should be covered. However, a Honda dealer in CA, mandated by CARB and EPA, refused to do the repairs or make any goodwill attempt on my behalf. I then reached out to American Honda, who delayed assigning a case manager as long as possible, then required phone contact after initially accepting alternate communication methods, then assigned a case manager whose hours conflicted with my stated availability, then assigned a second who has not answered the phone. I am still awaiting a callback. The vehicle has been immobile and in limp mode for the past two weeks while Honda's callback process remains unresolved.

While driving home during rush hour traffic on the highway with my children in the vehicle, without warning it stopped accelerating when I passed the gas pedal and started slowing down. When I let go of the gas pedal it would speed back up. I couldn't safely merge over to the right with heavy traffic and ended up on the left shoulder. I turned the vehicle off and tried to restart it, it struggled to start, but when I let go of the key it would turn over. The brake system lights and check engine light were illuminated after the incident, but not during. The code was for p0087 and honda service confirmed it's a failed high pressure fuel pump, but it's not under the recall so the repair isn't covered. I'm extremely lucky to have gotten to the side of the road without causing an accident. I was not driving my normal route that day, but if i had been this would have happened on a stretch of the highway that's under construction where there was no shoulder to pull onto. So if I'd have gone a different way home that day, we'd have most certainly been involved in a collision. They've anyway Texans the low pressure fuel pump but these high pressure ones are just as dangerous when they fail, even more so!

Head gasket/coolant leak. Dec 2 2025 my car started sputtering so I went into the AutoZone to use an obd2 reader for the check engine light. The code showed cylinders 2 and 3 were misfiring. I took it to the Honda dealership to fully diagnose the issue, they told me I needed new spark plugs but also that my coolant was low (they didn’t bring any concern for this) and just topped it off. They told me my fuel filter was recalled but the couldn’t service it cuz I had a full tank of gas. April 3 2026. Car started sputtering again but worse, it lost power and couldn’t drive more the 12mph. I assumed with the symptoms that the fuel filter was going out. April 4 2026 brought my car in to Honda for fuel filter replacement. After replacement was finished, the service tech said my coolant was almost depleted. And they don’t see any noticeable leaks. April 8 2026 car started sputtering again and I checked the coolant level and half the tank was gone. Brought it back to Honda for diagnostics There are thousands of Honda owners experiencing the same issue with the same engine (1.5L turbo). Honda made a deformed head gasket which causes the coolant to leak into cylinders 2 and 3. Head gasket blows requiring car owners to pay $5-$10,000 for repairs and in some cases, damages the engine beyond repair. Hondas negligence is causing its vehicles to be unsafe on the road. They need to be held accountable and the head gaskets need to be recalled
