2017 Honda CR-V fuel/propulsion system problems

“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 NHTSA 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.”

“For the second time this year, all dash warning lights activated. In April, it was diagnosed as a failed battery, which we replaced. This week, the warning lights came back. The car is at Bobby Rahal Honda now, and they say the fuel injectors are faililng. We have authorized the repair, which will cost $1900+. I have subsequently turned to Dr. Google and Grok, and fuel injector failure is a common, known issue for this model based on searches of NHTSA, Honda forums, and elsewhere--though our VIN is not currently showing any recalls, and our dealer is charging us full price for the repair. This appears to be a widespread problem with the 2017 CR-V, and I would suggest that this has significant safety implications. I would like to see this escalated to a full recall, with reimbursement for repairs already completed and paid for.”

“Over the past 6/7 months, the following: ALL warning lights on dashboard flashing whenever car in running, strong smell of gasoline detected in home garage, and 5/6 times during the past 4/5 weeks engine "rough" when starting cold accompanied by loss of power. The lack of effective warning notices and/or the sudden loss of power increases the risk of crash and injury. I understand that these are related to a known Manufacturer's defect. The dealer replaced the fuel injectors and provided some additional service. I understand that Honda has issued some "campaigns" and some vehicles have been granted extended warranties, etc. but I was told that this vehicle is not eligible. I would like to try to obtain reimbursement for the repairs since it appears to be related to a documented manufacturer's defect. I also understand that there has been a recall under this issue in Canada.”

“Emission warning light along with LKAS, ACC, Brake system are coming on the DASH. No driveability issues. The dealership in Walnut Creek pull code and find P0304 missfire #4 CYCLINDE, test #1 and #2 FAIL. Recommending to replace all 4 injectors.”

“All brake systems warning lamps illuminated while driving on the highway, the vehicle was pulled off the road and shut off, brakes were visually inspected and all fluid levels were examined and everything was intact. Vehicle was driven again after a breif time and everything was fine. A few weeks later all warning lamps were displayed, the vehicle was brought to a Honda dealership the following morning and a cracked fuel pump was diagnosed and the technician believed that there was no coolant in the vehicle and that was filled. The technicians suggested a scope of the engine to rule out a leaking head gasket but I could not afford it and monitored my coolant levels, had a pressure test done at a trusted mechanic and everything was fine for approx 3 months. Absolutely no coolant was observed on my driveway, the coolant level remained optimal on visual inspection. The vehicle started to drive roughly and I suspected new spark plugs were needed, those were installed at the dealership. The issue was not resolved and I returned w/in 1 month and was told that 3/4 cylinders were blown in addition to the head gasket. The vehicle has 106k miles and has received all…”
