2019 Honda Fit Engine Problems

The contact owns a 2019 Honda Fit. The contact stated that while driving at 40 MPH, several unknown warning lights illuminated. The vehicle was taken to a dealer for a diagnostic test. The dealer retrieved DTC: P0304 (ECM Detected Repeated Misfire in Cylinder #4). The dealer linked the failure to Technical Service Bulletin: 21-007; however, the vehicle was not covered under warranty or the bulletin. The manufacturer was notified of the failure, and confirmed the information from the dealer, and the contact was provided a case number. The vehicle was repaired. The failure mileage was 55,666.

All warning lights cycle through on vehicle dashboard after turning on vehicle. Vehicle was taken to Honda Auto Service Center, where issue is diagnosed as Carbon Buildup, causing misfires. Error Diagnostic Code is one of P0300 - P0304. After maintenance, error clears out. However, there is a Honda Service Bulletin 23-042 which provides a warranty extension for Honda Fits of the same year, make, and model with the same issue, which my vehicle's VIN was not included as eligible. Issue of carbon buildup causing misfires may apply to other VIN ranges than in that bulletin, as accounted by NHTSA ID #11462041, #11490506, #11549767, and #11593466

The contact owns a 2019 Honda Fit. The contact stated that while entering the driveway while idling, the accelerator pedal was not depressed when the vehicle accelerated inadvertently. The brake pedal was then depressed but failed to respond. As a result, the vehicle crashed into a building, a hose, and a palm tree where it came to a stop. The vehicle remained at the scene of the crash. The vehicle was not diagnosed or repaired. The contact sustained injuries to both knees and medical attention was required. A police report was not filed. The manufacturer was not notified of the failure. The failure mileage was unknown.

Four dashboard warning signs (Check Engine Light, Tire Pressure Monitoring System, Vehicle Stability Assist System, Electric Power Steering) appeared all at once suddenly. I had the vehicle towed to my local Honda dealership. They gave me a diagnostic code of P0304 and insisted that the repair did not fall under my car's active warranty. I searched the web and found it is a common problem in Honda Fits. Some 2019 Honda Fits have an extended warranty for fuel injection replacement, but it is not applicable to my car for an unknown reason. Relevant service bulletins: 23-042 and 21-007.

Dear NHTSA, I am submitting a complaint regarding unsafe vehicle service practices by Indy Honda, located in Indianapolis, Indiana. On December 8, 2023, I had my 2019 Honda Fit serviced at their dealership, including an oil change. On [XXX], while traveling on the interstate in Kentucky, my vehicle suddenly experienced a catastrophic engine failure. The vehicle’s lights illuminated without warning, followed by loud popping sounds, and it began smoking. As I slowed down to pull over to the side of the road, the car swerved and stalled. After investigation by Fidelity Warranty and a certified Honda dealership, it was determined that the engine failure was caused by an improperly tightened drain plug and crush washer, leading to a complete loss of engine lubrication. Despite providing substantial evidence and attempting to resolve the matter, Indy Honda has refused to take responsibility for the damages. This failure created a hazardous situation while driving at high speeds on the interstate, posing significant risks to my safety. I kindly request that the NHTSA investigate Indy Honda’s servicing practices and take appropriate action to prevent similar safety risks for other consumers. Thank you for your attention to this serious matter. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Fuel injector is going bad on my car at 80,000 miles causing catalytic converter to go bad based on two check engine codes. Recall done on 2015-2016 models so hoping this could be extended to 2019 as it seems they haven’t fixed the issue

While driving the emission system problem warning came up on my dash with the check engine light. After this happened it became incredibly hard to accelerate the engine. I was driving on the freeway and attempting to merge putting my life and my families at risk because the engine was trying to accelerate but sputtering and stopping for a moment instead. It hasn’t been inspected by police, but went to dealer and got code P219A and was told this was a faulty fuel injector. This was the first time this had happened and no other warning lights came on before the emission system problem that popped up on the dash.

Engine light came on and it was brought to the dealership and I was told all fuel injectors need to be replaced and it wouldn't be under warranty. The car has 65,000 miles on which is just over warranty, but I should still not have had to replace these yet. There have been other problems with the fuel system with the fuel pump recall and they have extended the warranty on fuel injectors in other Honda vehicles, which leads me to believe this is a greater problem than just my car and it should still be covered by Honda.

Fuel Injector failure in under 35,000... There is a misfire from one of the fuel injectors leading to a replacement of the entire system.
