Because after an automatic transmission car stalls, the engine stops rotating immediately, even if it is in D gear. The reasons why an automatic transmission does not move when shifted into gear are as follows: Torque converter not working: The torque converter shaft is locked, causing the fuel injection pump to stop working. Lubrication oil passage blocked: The lubrication oil passage is blocked, leading to insufficient lubrication, which results in the planetary gear carrier burning out. Oil pump shaft not working: The oil pump shaft is broken, causing the oil pump to stop working or the differential to lack oil and burn out. Oil pan damaged: The transmission oil pan is damaged, causing all the transmission fluid to leak out and leading to vehicle issues. Solenoid valve not working: The transmission valve body or solenoid valve is damaged and not functioning.

I've been driving for twenty years and have encountered several issues with automatic transmissions not moving when shifted into D gear. It happened once during a long trip when the car simply wouldn't move, and I found out it was due to a problem with the torque converter. Possible causes include dirty or insufficient transmission fluid leading to hydraulic system failure, or worn clutch plates preventing power transfer. Additionally, the gear lever not being properly engaged or a faulty control module can also trigger this issue. From my experience, if this happens, don't panic—first check if the engine is idling normally, then turn on the hazard lights and pull over to seek help. Regular maintenance is crucial, such as changing the transmission fluid and filter every two years, which can significantly prevent such failures. Never force the car to drive, as this could damage internal transmission components, making repairs more expensive and time-consuming.

How many kilometers can an engine still drive normally after slight water ingress?

It is best not to continue driving if the engine has slight water ingress. Here is the relevant information: 1. Filled with a large amount of water: When the cylinder is filled with a large amount of water, the engine crankshaft cannot rotate at all. Moreover, since water is incompressible, the piston has almost no space to move upward. At this point, even if the ignition switch is turned on, the starter cannot rotate, and naturally, there is no further damage to the engine. 2. Symptoms of water ingress in the engine: When there is water in the engine fuel or combustion chamber, the water is heated by the combustion heat in the cylinder and turns into steam, which is discharged from the exhaust pipe forming white smoke. If white smoke appears after the vehicle has been through water, it is highly likely that the engine has water ingress.

Is the Changan Yuexiang very fuel-consuming?

The fuel consumption control of the Changan Yuexiang is quite good, generally around 6-7L per 100 kilometers. Below is some relevant information about the Changan Yuexiang: 1. Interior: The touch and visual feel are quite solid, tapping on the plastic parts does not produce a hollow sound, and the plastic quality is above average. It features imitation leather seats, a sunroof, a decently sized central control screen, and electric rearview mirror adjustment. Overall, it doesn't feel too "basic," as the essential configurations are all quite complete. 2. Power: The Yuexiang is equipped with a 1.5L naturally aspirated engine and a 5-speed dual-clutch transmission. This 1.5L engine produces a torque of 145 Nm.

What causes the engine to make a humming noise and accelerate slowly when stepping on the throttle?

The reasons for the engine making a humming noise and accelerating slowly when stepping on the throttle are as follows: 1. Engine fuel pump issue: A damaged engine fuel pump leads to insufficient fuel supply. Even if the driver floors the throttle, the engine RPM increases, but the fuel injection volume remains low, resulting in reduced engine power output and naturally causing sluggish acceleration. 2. Valve timing issue: To improve fuel efficiency, modern engines use CVVD valve timing systems. However, if the CVVD hydraulic control system is damaged, the sealing ring leaks oil, or the CVVT malfunctions, the engine's intake and exhaust processes are affected, naturally reducing combustion efficiency and diminishing the engine's torque output.

What does the circle exclamation mark on the Qashqai dashboard mean?

Red exclamation mark (specifically a bracket circle with an exclamation mark in the middle) represents a warning for the braking system, mainly indicating a brake system malfunction or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark indicating a brake system fault, other exclamation marks on the car are yellow, representing general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cut-off system intervention or faults, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: A horizontal line under a bracket with an exclamation mark in the middle. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in one of the car's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or conduct a self-inspection, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the problem.

What documents are required for a six-year-old sedan's inspection?

Documents required for a six-year-old sedan's inspection: Original vehicle license; Original copy of compulsory traffic insurance; Vehicle and vessel tax certificate; Original ID card. If someone else is handling the procedure on behalf of the owner, the representative must bring their original ID card. After preparing the above materials, you can drive the car to the vehicle management office for the annual inspection. Here is some additional information: 1. Annual inspection: Annual inspection, also known as annual review in colloquial terms, refers to the safety inspection of a car conducted every year or every two years. It includes a comprehensive check of the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, etc. 2. Precautions: Before the annual inspection of a motor vehicle, you should first check if there are any traffic violations. If there are any violations, they must be resolved before proceeding with the annual inspection. Unresolved violations will prevent the completion of the annual inspection process.
