2017 Honda CR-V: misfire or rough idle

Filed Nov 3, 2026 · Engine · FL

• What component or system failed or malfunctioned, and is it available for inspection upon request? The cylinder head gasket failed, which subsequently caused the cylinder head to warp and the small engine block to crack (needs to be replaced). The vehicle's engine is currently completely disassembled at an authorized franchise dealership Lakeland Honda, and all components are fully available for inspection upon request. • How was your safety or the safety of others put at risk? The vehicle experienced sudden overheating, coolant loss, and severe engine misfires. If the engine is forced to be reassembled with a warped cylinder head—or machined outside of factory tolerances because the manufacturer refuses to replace the component—it risks a sudden, catastrophic engine stall or loss of motive power at highway speeds, creating an imminent crash and safety hazard for myself and other motorists. • Has the problem been reproduced or confirmed by a dealer or independent service center? YES. The failure has been officially diagnosed, confirmed, and the engine completely torn down by a certified Honda factory dealership - Regal Lakeland Honda. • Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? YES. The vehicle has been inspected by the manufacturer’s authorized franchise dealership technicians. However, American Honda Corporate is actively refusing to provide a written denial letter or follow their own safety bulletin repair guidelines. • Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Prior to failure, I had went for an oil change and the dealership had mentioned it as a warranty style recall. I had heard of it as well, and noted that there was rough idling upon cold starts, and rapid coolant loss without a visible external leak. These symptoms first appeared on August 1st, 2026.

While driving my 2017 Honda CR-V EX in Aug 2026, The dashboard illuminated with multiple critical warning indicators, and diagnostic scanning pulled code P0304 (Cylinder 4 Misfire). This created an immediate safety hazard on the road. A certified technician confirmed a premature failure of the gasoline direct fuel injectors. This component failure matches widespread defects documented in Honda TSB 21-010. The sudden failure of these factory injectors poses an unreasonable risk of engine stalling and traffic collisions.

2017 Honda CR-V EX-L AWD, 1.5L turbo. Vehicle has experienced persistent rough running/idle, random misfires, and hesitation/jerking during acceleration. Genuine Honda OEM fuel injectors were replaced and the system was recalibrated, but the symptoms have persisted. Spark plugs have also previously been replaced. I became aware of the federal safety agency Recall 23V‑858 involving fuel pump impeller failure in certain 2017–2022 Honda CR-V vehicles. Honda’s VIN-specific recall lookup currently shows no active recall for my vehicle. I am concerned that my vehicle may be experiencing a fuel-delivery problem similar to the condition addressed by Recall 23V‑858 despite my VIN not being included in the recall population. The fuel pump has not yet been confirmed as the cause. I am submitting this complaint so the symptoms and VIN are documented and can be considered in determining whether vehicles outside the current recall population may experience a similar defect.

Driver assist problems car braking and stopping without just cause actually causing safety issues. Computer issues. Computer replaced several times without resolving issues. Ongoing Engine issues reported to honda before the extended warranty was up. It wasn’t until after the extended warranty was up that American honda would address it. After numerous visits to different dealers for services finally this year I was told it was a head gasket issue. Honda refused to rectify or let in good faith making me come out of pocket more than 50% and purchase parts and honda refused to help I had to fight w them to get any help. I had to purchase the water pump and timing chain bc they wanted to put the old one on. They gave me 3 different significantly different quotes without reasoning. Then after receiving the car back over a month and a half later the car had safety issues stopping and braking on highway without reason. The car also still was sputtering and having issues w the engine. I called Westport honda (where I purchased it - where I had a lifetime warranty on the engine where they just finished doing to head gasket) they ignored me for 2 weeks letting me drive around w safety issues. Finally they told me to bring it in. After 5 days they checked it in and told me I had engine misfires. I requested all the computer print outs w previous repair but didn’t receive them. I contacted American honda to find out there was a safety recall never done by the dealer. I also found out there was an engine extension not told to me and I had to submit receipts to get reimbursed. Then I had to open a new case since the engine still isn’t fixed and has the same issues and yet Westport honda wants to pass the buck and charge me $3000 for more repairs making me come out of pocket thousands of dollars and have a car still not repaired. Honda should buy back the vehicle or fix and repairs all issues correctly without charging me. Honda is putting me and my child and family at risk!

For several months now, car has been misfiring, skipping and going into limp mode. Spark plugs replaced and issue went away for about 2 months. Issue has resurfaced and took it to Honda dealership where I purchased vehicle to run a diagnostic test. Informed to resolve the issue need fuel injectors replacement, spark plug replacements, coolant reservoir is empty and to top it off, need a head gasket kit.

The car misfires every now and then. For last two years (I bought it used two yers ago odometer=105k now 113k), it has been a repeated problem. A few times it lost all power and stopped completely. Once on highway. Once I had to get it towed. Another occasion it restarted after 15 minutes break as if nothing had gone wrong. This is very scary - I have reduced my driving and try to avoid highways as much as possible. It gives a code of P0302. It happens irrespective of hot or cold, speed or outside temperature. The mechanic repaired it - by changing injector coil, spark plugs, once even added injector cleaning fluid to see if the problem would go away. Plus top up the coolant. In the most recent mechanic trip - he tested for coolant leakage on head gasket and confirmed that is the problem. He also informed me that it is a widely known problem with this model (2017 Honda CRV 1.5L) although I wasn't aware of that when I bought it from a used car dealer, basically relying on Honda's reputation.

Cylinder 2 and 4 misfire, that will cause all the sensor lights to come on and the vehicle will stall out. Doesn't matter if driving 15 mph or 55 mph, it will just stall.

2017 Honda CRV Touring with VIN [XXX] . My son and daughter drove the car and all of a sudden all the lights started going off( it looks like Christmas lights). We got it scanned multiple times from different places where they have the scanner. It was showing P0304 Misfire #4 cylinder and U0401-68 ecm failure. We took it to the dealer and they found out the same code fuel injector needs to be replaced. I am single mom and didn't have the money to get it fix. Our car only had less than 21k. I stayed up to do more research online. Found out more about this common issues with same model. I contacted another dealer, explained my situation and he advised me to call honda corp to be added to the recall and mention goodwill. I immediately called the corporate but had to wait for their case mgr to get back with us. I asked my daughter to call the dealer where we got our car diagnosed, to ask svc advisor if it is safe to use the car and we were advised that it's ok to use. However my daughter was driving the car and all of a sudden it wasn't accelerating and only going around 5 miles per hour. She had to go back home and missed her classes. She was scared and I could just imagine how scary that was.How about if this happened when she was in the freeway? This could have caused a major accident. I don't understand why Honda only issued the recall to some cars with same model as ours if they already have lots of customers having same issue. I even read this issue was featured on ABC news. Honda did offer to help with lowering the fuel injector but I still have to pay $899.19 and around $204 for diagnosis. The svc advisor said they've been having a lot of same model cars coming in for fuel injector problems. I am reaching out hoping you can help direct us in getting the full reimbursement and hoping our car can be added to the recall so we can get reimburse.Honda should be fully liable for this due to known issue.

5th generation (2017-2022) Honda CRV displaying ALL driver assistance system errors (stability control, cruise control, emergency anti-collision etc), check engine light, tire pressure monitor malfunction, parking brake, and some other lights. *OBDII scan reads back P0303* Battery was replaced in 2025, and has never tested at low voltage. Recently tested battery 04/26/2026 at 14.51V (with engine running). Spark plugs replaced 04/26/2026 with OEM NGK plugs with OE Gap 0.030". Drove car for 10 minutes and lights didn't go away. Upon researching, this appears to be a "replace all fuel injectors" job. Which also appears to be a fairly COMMON issue in these CRVs. My concern is that the misfire is disabling all driver safety systems and forcing the car into limp mode, and seems to be manufacturer error/negligence in terms of part reliability/quality. These parts are also on a 6-9 month BACK ORDER because of how common the issue is. Honda released "Service Bulletin 19-032" as a means to make dealers aware of the issue but I find this dishonest to the customers and Honda owners who purchase the vehicles on the promise of reliability. Please look into this issue, as it seems to happen just outside of warranty on these cars. Honda scarcely giving out goodwill refunds/assistance for THEIR factory-issue.

On March 28, 2026, the check engine light illuminated on my 2017 Honda CR-V EX (VIN [XXX] ) at 59,057 miles. I pulled diagnostic trouble codes with a consumer OBD-II reader and recorded P0301, P0302, and P0303. On March 30, 2026, I contacted American Honda Customer Service to request goodwill repair assistance. I was told to obtain an authorized dealer diagnostic and resubmit. I did so. On March 31, 2026, I had Goudy Honda perform an authorized diagnostic (repair order #315466. Goudy confirmed the stored DTCs were P0300 (random misfire detected), P0301 (cylinder 1 misfire detected), and P0302 (cylinder 2 misfire detected). The dealer recommended replacement of all four fuel injectors at a quoted cost of $1,961.17 plus tax, and stated the injectors were out of factory, powertrain, and emission warranties. This DTC set (P0300–P0304 and P0172) is the exact set addressed by American Honda Motor Co.'s own Service Bulletin 18-124 and Service Bulletin 19-037. On April 10, 2026, Honda Corporate denied assistance on the ground that the vehicle is "out of warranty." On April 20, 2026, a Honda Corporate representative named Desiree called me to say that American Honda will not document in writing the reasoning for the denial and will send only a generic template. This matches the pattern of consumer complaints described in Bissell v. American Honda Motor Co which catalogs hundreds of similar ODI complaints and alleges that American Honda has known of, and concealed, a defect in its 1.5L i-VTEC turbocharged engine since at least 2016. Safety concern: misfire events at freeway speed produce sudden loss of power, limp-mode activation, and the risk of unexpected deceleration in traffic. The class complaint documents multiple incidents of sudden stalls and engine failures in comparable vehicles, including on highways. I am filing this complaint to ensure ODI has a record of this incident and to support any existing or future investigation of this engine.

Head gasket failed due to bolts stretching allowing coolant to leak into the cylinder on cold starts until the engine warmed and sealed itself. Was confirmed by Honda technician be causing a misfire on cylinder 4 throwing code p0304 and all warning lights on dash going off during cold starts only. Lead to unreliable transportation, slow acceleration, and even random parking brake engagement one time when waiting to pull out from a parking lot into traffic, in a vehicle supposed to be sold as reliable for families and to last over 200k miles with proper maintenance while this has happened at 140,000 miles despite proper maintenance and at no fault of my own, but as a design flaw that Honda is aware of and wont recall to fix causing major costly repairs.
