What are the serious defects of the BYD S6?

[Jesse]

BYD S6 has the following serious defects: 1. Noticeable noise: When the vehicle is idling, especially when cold, the noise inside the cabin is quite noticeable. To ensure the engine oil is fully and evenly distributed for protection during operation (idling stabilizes at 800 rpm, with instantaneous fuel consumption around 1.4), it takes more than three minutes to warm up the car, which is somewhat lengthy. 2. Overly hard brake discs: The excessive hardness of the brake discs leads to abnormal braking noises. 3. Abnormal noises from certain parts at high RPMs: Some components are not securely connected. 4. Key detection failure: While driving, issues such as the horn not working and turn signals not lighting up may suddenly occur. 5. Limited driver's space: The foot space is cramped, and releasing the clutch quickly can easily cause the left knee to hit the surrounding area.
