New thread as the last one has been retired due to members not obeying the Site Rules and spoiling that thread.

So we've started afresh....

Thanks.

2018 CrV EX-L with almost 67K miles and the vehicle is regularly maintained. Emission control warning popped up while returning from vacation and fuel mileage dropped about 5 mpg. Not running rough or idling badly, just lower fuel mileage and the code. Scanned with my cheap OBDI scanner and picked up a P219-F code which indicates either a fuel pressure or fuel injector problem on cylinder #4. I erased the code but it came back. Going to the Honda dealer this week to have them perform a more in-depth scan and get an estimate. Guessing from all I read its a fuel injector. Well post a follow up after the appointment
Attached is a you tube link which does a good job of listing the parts he purchased to replace the fuel injectors. Not sure they are all needed but given he labor to take off the top of the engine it is probably money well spent.

Thanks for this forum it has helped me narrow down what I think the issue is.

I forgot to add the video is for an accord but I believe the engine is the same 1.5l earth dreams. But some one with more knowledge can help.

Your issue may be an injector issue, but note that P219-F is not the usual code that pops when the injectors on gen5 CRVs start acting up and are resolved in the context of this thread tracking fuel injector quality issues. Other issues can cause a P219-F.

Back from the Appointment from Kunes Honda in Quincy Illinois. Verdict is fuel injectors need replaced at a cost of $1600. Even though we purchased the vehicle through them they did not offer to help offset the cost since the vehicle is 3000 miles of warranty. I contacted Honda Corporate and they opened a case. Waiting to hear back from them.

Thank You for the link showing the top tier fueling stations. I bookmarked this for future reference.
We are located in a rural area in Illinois and there is a shell station about 20 miles from us which I occasionally use when going in that direction. Typically, we purchase fuel at a local Casey's service station but not always or at a shell station in Missouri when going that way since fuel is about 50 cents a gallon cheaper. I almost always purchased 87 octane.
While in high school in the early 70's I worked at a service station and know about water in the fuel and cheap gas.
We just returned from a winter trip to Florida and drove 2600 hundred miles fueling up many times and although I try to pick either Shell or Exon that is not always the case. I wonder if that contributed to the warning but my driving and fueling habits are the same in the other fuel injected vehicles that I own and not having the same issues. But those vehicle do not have direct injected engines either.

The vehicle does not idle or run rough just the error message and loss of gas mileage (about 5mpg). I have cleared the code twice with my own cheap OBDI scanner before taking it into the dealership and the other repair shop. I would think if the issue was something related to a head gasket, fuel supply line or o2 sensor I would have pulled other codes. The dealer completed an in-depth scan and only came up with this code.

I have a son who is an ASE mechanic and he said the same thing about the code. It shows loss of power in the #4 cylinder and in todays cars you may not feel loss of power in one cylinder. I questioned that but I don't really know. I have replaced the plugs on a 2015 Dodge Caravan and if you know anything about those engine, the plugs required going through the top of the engine too. So I am not too worried that I cannot change the injectors myself I am just waiting to see if Honda is going to cover any of this since the vehicle is just 3000 miles out of warranty and this seems to be a know issue. If they do than great if they don't I may try to tackle the project myself if it warms up a little.
Anyway thanks for the helpful comments.

2017 CR-V with just under 49K easy going miles on it. I've been having the issues with the dash lights and P0172/P219F codes for a few months, but didn't drive it enough to worry about until now when emissions inspection is due. Dealership is charging me 1800 for new injectors, and I got nowhere with getting any of that covered, even with the low mileage. Very disappointed in Honda.

Total was $2233.10 after tax. It is killing me that if I had this car registered in California, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, or Washington this would have been well within the warranty of 7/70. But I'm here in NC where apparently clean air is not quite as much of a priority.

Follow up
I contacted Honda Corporate as some on this forum had previously mentioned. After going back and forth with paperwork for about 2 weeks Honda agreed to replace the fuel injectors at a final cost of $516 to me. It appears they picked up the labor and I just paid for parts. They did work with the local dealer but I am not privy to those discussions. Maybe having the recommended maintenance schedule up to date and that work completed by the dealer helped.
I have to say I was pleasantly surprised. I did not have to argue much and the Honda Case representative was very courteous. They offered that to me and I did not press for any additional compensation I figured it was a good deal given that I legally had no additional options.
I read an above post about using Tier 1 Fuel. The manual does not state it is a requirement only that it is recommended but with this type of engine it probably is a good recommendation. I plan to follow this advice and also carry and periodically use injector cleaner. I hope I can go at least another 70k miles without the same issue.

I have been following this thread. I had the same issue. 2017 Honda CRV with the 1.5 Turbo. It would sporadically get the Christmas Tree display of every warning light coming on and then would rotate through. Lights usually stayed on and went away. Some of the safety options, cruise control and a few other things wouldn't work until the warning lights stopped. This issue usually came up when I went through a car wash, but sometimes would happen for no reason at all. I had mentioned it a few times to my Honda dealership and they thought it could be nothing, or a sensor, but they would run a diagnostic on it if I wanted. They came back with P0172 and P0304. The dealer wanted to charge me $1700 to replace the injectors after charging $140 diagnostic. I had my letter from Honda and called Honda corporate and informed them that I had the same issue as in the letter I received from Honda. Honda said fuel injectors aren't covered under that additional powertrain warranty and that they would open a case for me. After a couple of weeks, I found out that Honda wasn't going to cover any of it. My vehicle only had 65,000 miles on it and I own two other Hondas; both of which have been to that dealer for service over the years and one of which was also bought there. I would have paid to get it fixed and for $500 or $600 bucks Honda would have continued to have a family that liked their vehicles and trusted them. I'm not necessarily upset that it's an expensive issue because cars have issues from time to time, even good ones, but more so because they know it's a problem. Just wanted to add to the thread after reading these past few weeks.

After reading these threads...there CLEARLY appears to be an issue with Gen 5 Honda CR-V Injectors causing the warning lights and associated issues that are being reported. The fact that an injector issue disables other safety items on this vehicle is highly concerning and I believe that angle should be pursued by the NHTSA.

One reader here stated that all the lights light up because today's vehicles are so interconnected. While that is true, an injector issue should NOT disable the safety features of a vehicle. That's like the equivalent of having a network printer issue and your computer decides it's not going to let you have basic features such as opening your office application or disabling your internet browser. Things may be "interconnected" but it does not mean they should automatically throw every non-applicable warning light at you and then prevent those other working components from operating - and thus lowering the safety features of the vehicle.

Another member on here tried to just chalk it up as, cars have issues (which is true of all vehicles) - and then tried to compare Kia to Honda - WOW!! The day an issue with the reliability of a Kia or Hyundai is compared to the reliability history of Honda, is a day we need to all stop buying Honda! Kia and Honda should NEVER been mentioned in the same sentence. They're not even in the same league as far a reliability. Comparing the reliability of a Japanese product with a Korean product will always be a non-starter in my book.

Concerning these injectors - I've read where Honda has asked dealers to send back the injectors for further analysis. Honda is clearly interested in the problem and the fact that they have helped pay for some of the repairs acknowledges the fact that they know there is a problem. BUT, I have to wonder, if the OEM injectors are a known problem, why would some want to put the same troublesome Honda OEM injectors back into their vehicles? Has Honda validated that replacement OEM injectors are better than the originals and will not have the same problems?? I think not, as that would make them liable for the bad original injector to begin with (note, I'm not a lawyer)!

As I've continued to read and learn more about this issue (and THANK-YOU to everyone for their stories and links to TSB's and YouTube videos), frankly I'm worried about the future of my vehicle and that Honda reliability we have come to rely on. I have no problem paying Honda to do this repair if I have to (but I'll probably use a local trusted independent repair shop to lower the cost and not pay to continue subsidizing dealers who will not do right by their customers). What really is concerning, is that others are also reporting additional issues with this injector issue, including future head gasket issues (heck, even one of the linked YouTube Video's here from a Honda Dealer Repair Tech up in Boston showing the replacement of the injectors indicated that head gasket issues are following this issue). I may just end up getting what I can from my CR-V in trade towards the Acura MDX (although, that is also a direct injection engine as well).

Again, thanks for ALL the comments, both good and bad not so-good comments!!

UPDATE:

Rcvd a new code today - P0303 - 3rd cylinder misfire

Of course, ALL the warning lights and chimes lit up on the dash - Cruise control and other safety features appear to be disabled.

-----------------------------------------------------------------

Note:

Honda's Technical Information & Support Group sent out an email to dealers in Feb 2022 - requesting they send possible bad injectors back to them.

Does anyone know more about this and why they only requested, "2018-2021 Accord 1.5Ts & CR-Vs with a customer complaint of the Malfunction Indicator Light (MIL) on with the DTC P030X (Cylinder Misfire Detected) or P0172 (Fuel System Too Rich) stored"?

What happened to 2017 CR-V's having this same issue (as is well documented here in this thread, the prior thread, and numerous other threads on this site and others.

21k views, 9k view, etc... That's a LOT of views on YouTube of folks looking at Honda Injector issues!! This is NOT a small issue for Honda. Think of all the people who will never research this issue, either here or YouTube, and just fork over $1,400 to their local Honda dealership! I wonder when we'll start hearing of the first set of folks on their third set of injectors within 10 years of the 2017-2018's! I have a 1999 vehicle with its original injectors!

So I finally got my turn at this issue. All dash lights/warnings came on while driving. Took it to local dealer and they said it's due to faulty fuel injector. Good news is, it's all covered under my extended Honda warranty which goes to 120K miles or 8 years (the car currently has ~91K, purchased in 2018), including the $240 diagnostic fee. The BAD news is, the injectors are on backorder and dealer has no clue when they'll come in. The service rep says it could be days or months. This was a week ago. I'm not sure how much longer to wait before I: buy another car or just pay and have my regular local mechanic do the job (though, if the injectors are back ordered, it would be the same for anyone trying to order them).

I have a 2019 Honda CR-V with 53k miles and have had the issue with all dash warning lights coming in since September 2022. Have done several things to diagnose: new battery, resetting the codes, checking sensors, etc. Still comes up. Recently the emissions warning and check engine light have been the only lights coming on after resetting the codes. Then without fail, all lights will come on after driving a little longer. The codes are saying that it most likely is the injectors. I finally called my local Honda Dealership and they said the original fuel injectors are no longer available. They are now using a kit that includes injectors and a u shape pipe connected to the fuel rail? $652 out the door for that. But that is on a national backorder with no ETA. So frustrating!!

Finally I called honda Canada, they told me why would look if they could help me.. 2 days later told me I was too far from warranty ( 119 000 km without extended warrenty) and that I have to pay for the repair (around 2000). While driving around locals mecanics around my town I was told the pieces were too hard to find or to deal with the dealership in case of further problems. One of them told me it was worth trying changing the sparks plugs since they were kinda due and roll with a fuel cleaner before going for the injectors. After 2 days all lights came back and my car stop accelarating after a stop once again. Im gonna call my honda dealer for an appointment today.. I'm really disapointed of the product.

I have a 2017 CRV 1.5L that has had intermittent P0172 codes come up over the past 4 months. I took it to a Honda dealership and they first diagnosed it with running rich and it needed a new A/C control unit, software update, and tune up. We did this and it was fine for about a month but now the code comes up again. It seems to only happen when the car has been running, it gets shut off, and turned back on shortly after. Honda says we need to replace the fuel injectors now, but they are back ordered with no ETA. The car is not backfiring nor has it lost any fuel efficiency, so I am not sold on the fuel injectors being the issue. Any body else had this issue, and if so, what seemed to be the fix? The car has 80,000 miles so injectors failing surprises me at this mileage already.
Thanks

Thought I'd follow up....a few more weeks now and still no word from the dealer on the injectors. They say a lot of people are waiting on them as well, they're still on backorder though. I emailed one dealer (hondapartscheap.com) and they said they don't have any but sent me a list of all dealers in the country that do have them. So I showed this list to my own local dealer and asked if they can obtain the parts from any of these dealers on the list and they said that a lot of these other dealers' inventories aren't update and/or, even if they do have some in stock they are not going to want to part with them. So my guess is, if a dealer DOES happen to have them, the only way they'll part with them is if they're the ones doing the actual work. Unfortunately on this list (which is oudated by now because it was from last week), none of the other dealers are anywhere close to me.

On another note, I saw a some other recent posts here saying that their dealer told them that this fuel injector issue is not covered by the Honda extended warranty. Has this been everyone's experience? My dealer told me it woudl be covered under my Honda extended warranty.

Its covered if you have extended warranty thru Honda care.

So, the parts finally came in and I had the work done yesterday. All told, it wasn't nearly as long as I had expected (the dealer had said it could take days to months for the parts). In the end it was actually only three weeks. All covered by the extended warranty ($0 out of pocket). The service rep said they had a bunch of people waiting on these injectors and so they were pretty busy doing this job on multiple vehicles that day.

1st update.
Was able to get out there with my BlueDriver Trouble Code reader today. P0172 was showing...I erased it.

Battery Readings: 14.3 Volts while running. 12.6 while turned off
Battery is the Honda Recommended size (51R) Interstate Battery (2years old) - I upgraded my Accord Battery the last time I had to change out its battery...I'll upgrade this battery to the larger size when this one dies.

Disconnected the battery for an hour

Started the car up, after the 1hr battery disconnect and the codes were still there...drove down the street and the codes all went away! Kept driving (beautiful Saturday!) for an hour (mostly 40-50 mph on back country roads) to test that the MPG was still good - after an hour it was reading 37MPG. Car drove fine - no trouble codes showed up again - even took it through a car wash! Restarted the car a couple of times and no codes popped.

I had the BlueDriver scan tool doing a live scan of the data during the drive. - I recorded a bunch of settings that seemed important but clearly the tool is smarter than I. I don't know what to do with the data but I've e-mailed it to myself to look at later - looks like it is in Excel format.

I guess at this point, I'll just be waiting for the Christmas Lights to go off on the dash again.

In the meantime, should I reach out to my dealer and let them know and asked about the extended warranty coverage for the P0172 issue? I need to read these threads and see more about this...and if Honda is covering it. My car is 5.5 years old. I've got 5 months until I reach 6 years old (I think that was what I read was the extent of the extended warranty coverage of this issue.

they told me that they are no longer making the part that they use to bc it didn’t work right so they are being redesigned. With no time frame.
Hmmm....my dealer finally got their stock in a few weeks back and I was able to get my car repaired and back on the road. But based on your comment, my injectors are just the same injectors as previous, but new. I suppose then it's just a matter of time before the same issue happens again? Considering this happened to me at ~91K miles.....I'm going to think positive and assume I'll get another 91K miles out of these injectors :D

Thank you for that advice. Not sure if I will ever buy a Honda again after this experience. My service advisor recommended we not drive the vehicle until it is repaired and since this is my only vehicle I am at my wits end.


Did you ever get your parts? We have been told the same and it's been a week. I can't believe this could take months to resolve. So frustrating!!!
Yes, my dealer (San Leandro, CA) did get the parts (all told, I waited only three weeks) and I was able to get my car back on the road. I had the Honda Care Warranty (8 years / 120K miles), which covered everything (see my previous post). The warranty cost $1800 back in 2018 when I bought the car and the cost of the parts/labor for the injectors was $1300....so not quite breaking even yet. I wasn't aware that third party warranties were still a thing these days?
