Here are the reasons for the disc brake caliper piston not retracting: Brake pedal malfunction: Aging of the brake pedal can cause the pedal's spring or screws to become loose, resulting in symptoms such as slow or incomplete brake return. A detailed inspection of the car's pedal is required, and damaged parts should be replaced promptly. Low brake pump pressure: There are many reasons for low brake pump pressure, including blockage in the brake system management or air leaks in the brake booster. It is necessary to visit a repair shop or 4S store for professional inspection and repair. Lack of brake fluid: Insufficient brake fluid is a major cause of incomplete brake return. It is important to check the brake fluid regularly and replace or replenish it as needed.

Will using 95-octane gasoline harm the Sylphy?

It has no negative impact at all. Most engines can use 95-octane gasoline. 95-octane gasoline provides better overall power performance and makes the engine run more quietly. It also delivers stronger performance during subsequent usage. You may consider this option based on your vehicle's actual conditions. Overall, if your car's operating costs don't require strict control, I recommend directly choosing 95-octane gasoline as it offers relatively better safety, comfort, reliability, and stability.

Why is one door not locked after the doors are locked?

Door lock motor failure is usually caused by insufficient motor power failing to pull the lock into position, or a dirty lock mechanism lacking lubrication that increases motor load. If the motor connector has good contact, replacing the door lock motor is required to resolve the issue. Check if all doors are properly closed. Inspect the door lock latch for any abnormalities. Introduction to automatic speed-sensing door locking: This electronic device automatically engages the door lock buttons when the vehicle reaches a preset speed (typically 10-20km/h as factory-set) to prevent accidental door opening while driving.

What Does the Turtle Warning Light Symbol Mean in New Energy Vehicles?

It indicates a malfunction in the vehicle's powertrain system. Here is some relevant information about new energy vehicles: 1. Advantages: The most notable advantage is significantly reduced pollution, as these vehicles achieve better energy efficiency and environmental protection since they don't rely on combustion engines and thus produce no exhaust emissions. They also offer pricing advantages with certain purchase subsidies available, helping buyers save on costs. Additionally, these vehicles operate with minimal noise, providing a comfortable driving experience. 2. Vehicle Classification: Pure electric vehicles can be registered with green license plates. Fuel hybrid vehicles belong to the conventional vehicle category and are not classified as new energy vehicles, thus ineligible for green plates. Plug-in hybrid vehicles qualify as new energy vehicles and can use green license plates. Range-extended hybrid vehicles are also eligible for green plates.

Is the insurance still valid after transferring the car to someone else?

Answer: After the vehicle is transferred, the insurance remains valid, but an insurance transfer must be completed, which involves processing the modification of the compulsory motor vehicle traffic accident liability insurance contract. During the validity period of the insurance contract, if the insured vehicle is sold, transferred, gifted to someone else, has its purpose changed, or its risk level increased, the insured must notify the insurer in writing in advance and apply for an endorsement. Otherwise, the insurance company has the right to refuse compensation. Article 18 of the "Regulations on Compulsory Motor Vehicle Traffic Accident Liability Insurance" states: When the ownership of the insured motor vehicle is transferred, the modification of the compulsory motor vehicle traffic accident liability insurance contract must be processed.
