The check-engine light comes on immediately before the vehicle loses the ability to accelerate. While driving, including at highway speeds, pressing the accelerator does not produce normal propulsion and the vehicle loses motive power. If I pull over, turn the vehicle completely off and restart it, the check-engine light clears and normal acceleration returns. The problem is intermittent and has occurred more than once. The dealership has previously been unable to identify the cause because the vehicle operates normally after restarting.

I am the owner of a 2020 Honda CR-V equipped with the 1.5L turbocharged engine. The vehicle is experiencing a severe and dangerous engine oil dilution manufacturing defect where unburnt gasoline enters the oil pan. This is an active driving hazard. After a fresh oil change meant to remediate the issue, the oil level rapidly rose back up past the top dipstick indicator within less than 200 miles of driving, and the oil smells strongly of raw gasoline. This severe dilution degrades the engine oil viscosity, creating an immediate risk of sudden engine stalling, loss of propulsion, or catastrophic internal engine failure while driving at speed. Honda is aware of this defect on 1.5L turbo engines but has failed to issue a recall or provide a permanent engineering solution for 2020 models. I currently have 44,443 miles on the vehicle.

On the evening of [XXX], I started my vehicle while it was parked in my garage. Within approximately five minutes, the vehicle suddenly produced a violent and unusually loud mechanical noise, followed by visible smoke billowing from beneath the hood. Recognizing the immediate potential fire and safety hazard to both myself and my property, I immediately shut the vehicle down. The following morning, I took directly to Honda North, an authorized Honda dealership in Clovis, California, for a professional diagnostic inspection. The dealership's certified inspection determined that the A/C compressor had suffered a catastrophic internal mechanical failure and had completely seized. According to the dealership, the compressor's internal failure while the system was operating resulted in metallic debris being circulated throughout and contaminating the A/C system. This catastrophic seizure heavily strained the engine's drive belt system. The failure was a direct result of the factory compressor shaft seal leaking out all system refrigerant and lubricating oil, causing the unit to run dry and seize. As a result, the dealership determined that replacing only the failed compressor would not be sufficient to properly restore the system. The recommended repair requires a complete A/C system overhaul, including replacement of the compressor, condenser, expansion valve, and associated refrigerant lines/components. Honda has openly acknowledged this exact factory defect in Service Bulletin 23-040, extending the shaft seal warranty to 10 years. However, Honda Corporate Customer Service is refusing responsibility for the downstream consequential destruction caused by their own defective component, citing only general vehicle age and mileage, despite the vehicle having 55,782 miles and sitting well within the 10-year extended warranty window. They have refused to provide an engineering justification or written analysis for this safety-related coverage denial. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

When driving on highway, the engine light came on and the car suddenly slowed down causing me concern about traffic around me still going at highway speed. Not understanding what the issue was and afraid the car would lose all power, I was able to shift lanes quickly to get to the breakdown lane. I was able to get the car to Honda Dealer driving at slow speed using back roads. The Honda Dealer confirmed an engine misfire caused the engine light and slowdown. The cause of the misfire was coolant leaking into engine cylinder and would require replacing the head gasket to fix the problem. The car had 75,000 miles and had been running fine until that point.

I got onto the free and accelerated to the speed limit. I glanced at my dash and saw the check engine light start flashing. I could feel the car start to lose power and handle differently than normal. I immediately pulled to the shoulder and had the car towed to the dealership. They diagnosed it as having a blown head gasket and that coolant had gotten into 1 of the cylinders. The adviser informed me that 2018-2022 1.5 turbo and hybrid engines have been having issues with blown head gaskets. I had also been seeing complaints of that on social media before this happened to mine. My vehicle has over 100k miles and it isn’t even 6 years old. I have had older Hondas, acuras and Toyotas with similar mileage or more and no issues like this. If so many drivers are having blown head gaskets Honda needs to be looked into for this and have a recall to repair their defect. The service adviser told me it was nothing I had done to my vehicle to cause this. I get oil changes when the maintenance light comes on and I have completed scheduled maintenance on my vehicle. I also use Costco gas 95% of the time and only use other brands when traveling.

My 2020 CR-v hybrid has suddenly lost power on the freeway a total of 4 times in the 6 years I've owned it. It is always at freeway speeds. The flashing engine light appears and the car loses power. After pulling over, turning off the car, and waiting a few minutes, the car can be turned on and driven with no more flashing engine light and no more problems for months. Each time I've taken it to the dealer and each time they haven't been able to replicate or find the problem. I've been told that error codes were not generated. I purchased my car new in July 2020, and the power-loss incidents were: - Fall 2020 - Summer 2022 - December 2024 - June 2026 A google search shows that many other crv hybrid owner have experienced the same problem, and also have had service technicians unable to find problem. This is a major safety concern.
