Will Toyota’s increase in engine oil go unnoticed?

Two years ago, the CR-V was stuck on the gas pedal, its sales fell to freezing point, and it was mercilessly ridiculed by rivals on promotional posters. Nowadays, "the tide is turning", Toyota has also been involved in the oil increase and emulsification incident, and the "Toyota that can't be driven bad" has also been questioned. Before there is a formal official response, the incident continues to ferment on the Internet. However, there is no "delay" in Toyota's response this time. Recently, the relevant person in charge of Toyota China responded to the oil incident (the following description has been compiled): Toyota official: It is a normal phenomenon and does not affect the use of the product. The relevant person in charge of Toyota China responded to the domestic When interviewed by the media, he said: This is a normal situation and will not affect the use and safety of the vehicle. Customers can use the vehicle with confidence. If consumers are still uneasy about the above-mentioned phenomena in their vehicles, they can go to the dealership for vehicle inspection. And it is particularly emphasized that we have not received any feedback from consumers about vehicle failures caused by the above situation. In addition, FAW Toyota self-examined 249 vehicles with excessive oil content and found no fault. And in response to the increase in engine oil, there may be the following four reasons: 1. The engine factory injects engine oil based on the F scale line, but there is a certain tolerance. There are cases where the actual oil injection exceeds the F line, but it is still within the specified range. 2. In addition to new cars leaving the factory, the oil level may also exceed the F line during vehicle maintenance and oil replacement. 3. Judging from the working principle of the engine, during cold start at low temperature, a very small amount of incompletely burned gasoline enters the engine oil through the gap between the piston ring and the cylinder block. 4. When measuring the oil level height, whether the ground is flat and the oil temperature also have an impact on the oil level height. As for why engine oil emulsifies? FAW Toyota's response was that the engine repeatedly failed to fully warm up. When used when the water temperature was below 80°C, a small amount of condensation water in the engine could not evaporate and was mixed into the engine oil. In this case, the oil filler cap will become emulsified. When the vehicle is running at high speed and the engine is fully warmed up, the small amount of water mixed into the engine oil evaporates and the emulsification phenomenon disappears. This increase in engine oil is concentrated in models equipped with the A25 series hybrid system. When hybrid system vehicles are driving at low speeds, compared with gasoline models, the gasoline engines of hybrid models start and stop more frequently, so this phenomenon More likely to appear on hybrid models. Although there are recalls in North America, they are not involved in China. Not long ago, Toyota and Lexus recalled more than 40,000 hybrid models in North America. Therefore, some domestic media combined the two things and suspected that there were gaps inside the engine, causing coolant or oil to leak from the cracks. In this regard, Toyota Motor (China) stated: The recent recall of the North American RAV4 model that has attracted attention from all parties is a manufacturing problem that occurred in a specific overseas engine manufacturing plant during a specific period. After investigation, it was confirmed that the RAV4 series models and Avalon models produced by FAW Toyota do not have the same problem due to different engine supply factories, so they are not affected by this recall. How to solve the problem of increased engine oil in CR-V and CS75? Looking back at the previous Honda engine throttle incident - CR-V due to design reasons, when the vehicle continues to drive short distances in low temperature environments, the engine oil level will increase. When the oil level increases to a certain level, the engine fault indicator light will light up. Continuous operation of the vehicle in this state may cause engine damage. Dongfeng Honda's solution is to replace the air conditioning control unit and upgrade the FI-ECU software for free for the vehicles within the recall scope. For models equipped with CVT transmissions, replace the radiator drain pipe assembly and upgrade the TCU software at the same time to suppress the increase in engine oil level. , eliminate safety hazards. When the recall is implemented, the engine oil and oil filter will be replaced free of charge for vehicles within the scope of the recall, and engine cleaner will be added. In addition, Changan, which also has the problem of increased engine oil, has some CS75 models equipped with 1.5TGDI engines. The engine electronic control unit (ECU) software lacks control over the vehicle's engine fuel injection strategy adjustment under extreme conditions. When the vehicle is exposed to low temperature environments for a long time and for short periods of time, When driving long distances, there may be an increase in oil in the oil pan. Changan's solution is to inspect the vehicles within the recall scope, upgrade the ECU software and engine cooling system, and implement a lifetime free warranty for engine-related parts. Consumers Can’t Get a Solution Returning to the consumers themselves, Toyota did not provide consumers with a satisfactory solution, which can even be understood as “not providing a solution.” I did not see any "relevant statement" on Toyota's official website and official account. The above-mentioned "official response" was very passive and was only the response of "the relevant person in charge of Toyota" in an interview with domestic media. Therefore, dealers can only wait for news from the manufacturer. It is still unknown whether the free maintenance period for engine-related parts will be extended. The current solution is: dealers help car owners replace new engine oil for free (not a solution given by the manufacturer). If compared with the previous CR-V and CS75, in fact, the Toyota A25 series "is not a big deal" this time. There are not a large number of car owners defending their rights. There are only scattered car owners "seeking help from self-media" on social networking sites. , is the matter not big enough? Assuming that the incident does not continue to ferment, it may eventually come to nothing, and new car sales will not be affected.
