This is a widespread defect on 2018 1.5L Turbo engines that poses an active driving hazard.

Car abruptly lost power while driving. I was barely able to pull over to the side and park the car in lot that happened to be next to where I was driving. The car was towed to a award-winning service facility (non-Honda) and it was determined that P0303 Cylinder Misfire and P16e8 engine error codes due to a blown engine head gasket. According to the head mechanic, they had recently had another Honda CRV experience the same issue. The replacement parts/kit/labor cost almost $4,000. Without it the car was undriveable, most concerning was the abrupt loss of power, thankfully was not on a highway when this happened as there had been no warning or degradation in performance prior to the issue occurring. In searching the internet, apparently many others with Turbo CRV's are reporting this type of issue? I contacted Honda and they were basically of no help other than suggesting I have the car towed to a dealership but with no guarantees that they would cover anything given the 'age' of the vehicle. It has been a very well maintained car.

Every warning light possible randomly came on a few months ago. The lights stay on for about a week, then go off for about two weeks. Took to Honda, first time they said nothing was wrong and preformed a relearn. Lights were all off for 300 miles, then came back on. Took back to Honda and they diagnosed as fuel injector misfire and quoted me $1800 for replacement. I was doing research and found that premature fuel injector failure with the 2018 CRV is a known issue. My local mechanic tells me it's a safety issue to drive around with misfired cylinders and can damage the engine. When the lights are on, none of my car's sensors work and I cannot use cruise control. I do not have $1800 to spend on something that should be a recall. I have only had the car 2 years. Thank you so much for your time and assistance.

Cylinder head gaskets failure with coolant migrating into the cylinders, available for inspection upon request; Dahl Honda Sheboygan took videos of inspection and liquid in the cylinders. Upon starting the car, the engine sounded strange and sluggish. As I started to drive, engine sounded like it was misfiring. I was able to drive only 10-25 mph (safety issue) from residence to the Dahl dealership (2.8 mi). All electrical warning lights were flashing. I thought it was my battery or a loose connection. They appeared all at once upon starting the car that morning, no prior warning.

I was driving on highway at 55 MPH speed, suddenly dashboard starting blinking (On and off) with some noise. I shocked to see that suddenly while driving on highway and I pulled my vehicle to shoulder and stopped vehicle. I started engine again after few mins and noticed all alights pop up on dashboard and it keeps continuing poping all lights. I took vehicle to Honda dealer service center. They did inspect and told me it is known issue for Honda vehicles. They said head gasket misfire and coolent leak through the head gasket, leading to a misfire. They estimated around $8000 USD for repairs. I am reporting safety concern and financial pressure on vehicle owner. Very much dissatisfaction when I see it is not added to RECALL when there are numerous compaints with same issue. This has to be added to RECALL immediately as it is known issue troubling many customers and it may cuase accidents on highways. It is potential safety concern on road and mental stress due to expensive repair.

The engine throw a P303 Code with a cylinder 3 misfire. Using coolant at a rapid rate as well. We have change the spark plugs numerous times, put in new coils and replaced the fuel injectors. This is with all Honda OEM Parts. There is an issue with the Headgasket. The car looses power and has left me sit on the side of the road. I will not drive it as this time due to safety concerns. The CRV is services at our local garage since the dealer is to expensive. This service center has been working on this CRV for the last few years. The garage is a well respected service center in our community. This issue has been going on for a month or two. All of the dashboard lights come on and then I loose power. When it does work, it will sputter when starting and then sputter at times while I am driving it. I know there has been a class action lawsuit filed because of this same issue but I am being told my VIN number does not fall into that category. I do not see how that is right when I am having the same issues with my car that is described in the lawsuit.

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.

Failed Head Gasket in the engin affected fuel injectors and spark plugs to fail or not perform normally and started misfiring in the engin. My 24 year old son drives this car and the problem happened at night when he was driving home at night on 3/4/2026 flashing all waring signs on the screen. The car's speed was abruptly reduced to very low and he was not able to drive the car . I put the car to repair shop and replaced the fuel injecton kit and spark plugs and paid $1650 for that and the problem happed again with same kind of signs and drop the car to dealership for detailed diagnostic analysis and they came with the conclusion that the engin has a failed head gasket which causes the engin coolent to enter into cumbustion chamber and mix with the oil/gas affecting fuel injectors and spark plugs. Upon extensive search on internet and social media , it has been found that there are hundreds of victims who own the same year vehicle & model ( or same engine types ) and faced same issues and paid too much money to repair even though the Honda is aware of the issue and not taking care of it. Honda is playing with american people's life when they know the issue very well and haven't done anything yet to recall the vehicles to resolve this issue . This need to be investigated thoroughly to save life of innocent people.
