While operating my 2024 Honda CRV Sport - L Hybrid, the vehicle experienced a sudden and catastrophic head gasket failure at 108K - miles. This resulted in an immediate, unexpected loss of engine power. The dashboard engine light came on "Emissions system problem. Power may be reduced. See your dealer. This sudden loss of propulsion created an immediate safety hazard, placing myself and other driver at risk of a rear-end collision. The vehicle was towed off the freeway over 45-miles to a certified Honda dealership where a blown head gasket was confirmed. Despite maintaining the vehicle perfectly according to Honda's schedule, this represents a premature mechanical engine defect that presents a severe road way safety risk.

The vehicle has been in 3 times for shaking and check engine light. First time the Honda technician diagnosed as misfire cylinder 2 issue caused by bad injector. The dealership indicated that Honda would not honor warranty fix if the car did not store the error code on the computer even though "big safety issue." Second time a 60 minute software update was authorized by Honda. Third time 3 error codes were shown: power, transmission, emission. Screenshots provided to dealer but the car computer did not store the codes after the incident. It appears the software is designed not to store the code for intermittent issues by design. First incident documented along with the bad injector causing cylinder misfire at dealership on 5/18/26. I have video of this inspection sent by dealership to me on this date as evidence. Car taken to dealership again on 6/19/26 with same vibration and error codes. Only software update approved by Honda. 4th of July car began to shake and again provided multiple codes. By the time the dealership was open on 7/6/26 the computer showed no codes and Honda would not authorize repairs under warranty. In the video, the dealership admits to finding a serious problem and they verify it, but they claim they cannot fix it unless the computer gives them a code. We were told Honda programed the computer to not store the error codes which appeared indicating to contact the dealer. I have photos of all and they were submitted to the dealer but it is not enough for Honda to honor the warranty or to fix a known safety issue.

My car was sitting in idle with the engine on for approximately five minutes, then all of the sudden the engine started to make loud tractor engine-like loud noises. The dashboard was bombarded with warnings. I turned the car off, and waited a few seconds. After I restarted the car, the check engine light turned on and the system reverted to one warning on the screen which read "Emissions system problem. Power may be reduced. See your dealer."

Long story short, I was driving my car and had noticed that when the engine would turn on from EV mode, it would idle rough and sometimes sound like it was struggling. I had it checked when the recall came in for my steering gearbox and they said nothing was wrong. Cue 600 miles later, every check engine light comes on and my car is loud as it gets. I call and take it to Honda and they tell me that since my car “cleared the code” itself, they can’t find it and I have to wait for it to maybe come back. As of yesterday, I went cause it started doing the same stuff as described above and they ran diagnostics on it. All 4 of my fuel injectors on the car have failed and need to be replaced. My car has less than 11k miles on it and all 4 of my injectors have gone bad? This isn’t just a me issue this is going on all over cause the service manager called another rep and the dude said he has seen it before too.
