Honda has resolved the issue of excessive engine oil. The relevant details are as follows: 1. Dongfeng Honda announced: To reduce excessive engine oil, an ECU upgrade will be performed, and a recall is being prepared. The CR-V will be recalled by the end of February, and the Civic will be recalled in early March. The markings on the oil dipstick will be adjusted—the upper and lower limits will remain unchanged, but an additional marking will be added to confirm excessive oil levels. Additionally, the user manual will be revised. 2. Brake failure: Apart from the issue of excessive engine oil, another serious quality problem with the Honda CR-V is brake failure. Based on numerous fault scene photos provided by owners, the vehicle malfunctions are largely similar. After the fault occurs, various warning lights appear on the dashboard, including those for the vehicle stability system, power steering system, low tire pressure warning, and brake system warning.

I've been driving Honda cars for over a decade, with particular focus on the CRV series. Around 2017, the oil dilution issue became quite prominent, mainly caused by gasoline mixing into the engine oil during short-distance driving in small-displacement turbocharged engines, leading to increased oil levels. Honda conducted multiple recalls and software updates, such as adjusting the fuel injection system and ECU settings. For the 2021 CRV model, based on forum discussions and car owner groups, complaints have significantly decreased, indicating the issue is largely resolved. During my test drive of the 2021 model, I noticed the engine runs more smoothly without the previous problems. However, I still recommend new car owners to regularly check the oil dipstick during winter or frequent short trips to ensure the oil level doesn't exceed the maximum mark. If any abnormalities are found, visit the dealership for free service promptly. By the way, maintaining long-distance driving habits allows the engine to fully warm up, reducing the risk of malfunctions. Overall, Honda handled this situation quite well.

As an automotive enthusiast, I know the oil dilution issue in the Honda CR-V originated from a design flaw in the 1.5T turbocharged engine, where incomplete gasoline combustion caused fuel to seep into the oil. Starting in 2019, Honda gradually optimized components and software, and by the 2021 CR-V model upgrade, the problem was largely resolved. Data shows recall rates have significantly dropped. However, if you drive a 2021 model and frequently take short trips in cold climates where the engine warms up slowly, slight oil dilution may still occur. It's advisable to check the dipstick monthly when the engine is cold—the oil level should be between the upper and lower marks. If you notice foam or unusual odors, an oil change or fuel injector inspection may be needed. Honda has also enhanced engine monitoring, and owners can install an OBD diagnostic app to track real-time data. Under normal driving conditions, this car is quite reliable.

Our family bought a 2021 CR-V mainly for transporting kids, so safety is a top priority. After researching, we learned that oil dilution used to cause engine wear or trigger warning lights, but Honda issued technical fixes for the CR-V, and the 2021 model is basically problem-free. During maintenance, the technician mentioned they optimized the engine's intake system to reduce cold-start issues. In real-world driving over a year, we haven't encountered any malfunctions. To be extra cautious, I check the dipstick before each refuel to prevent high oil levels from affecting driving. Regular oil changes also help protect the engine. Honda offers an extended warranty policy, providing free repairs if any abnormalities are found, which gives us peace of mind.
