Why does the car stall in D gear?
2 Answers
The reasons for a car stalling in D gear are as follows: 1. The use of poor-quality fuel affects the engine, causing excessive carbon deposits. 2. There are mechanical issues with the engine or transmission; or the driver is unfamiliar with the operation. 3. Additional information: D gear stands for Drive, which allows the car to maintain forward motion when engaged. When the car's battery light turns on and then off, it is important to avoid randomly turning the steering wheel or repeatedly pressing the brakes. This is because the car's steering and braking systems generally require power assistance. After the car stalls, there are usually only two opportunities to brake, so they should not be wasted.
I remember encountering this situation last time in my friend's car. His automatic transmission suddenly stalled after shifting to D gear, and the engine shut off. This issue is commonly caused by engine system failures, such as aging spark plugs leading to ignition failure, or insufficient fuel supply from the fuel pump, especially when sudden load increases occur during low-speed driving. Additionally, gear-related components like the neutral safety switch might be damaged, causing the system to mistakenly think the car is in neutral when it's actually in D gear, triggering the stall protection. I recommend first checking the condition of the spark plugs and trying to replace them. The fuel filter might also be clogged and need cleaning. If the problem persists, it's best to take it to a professional repair shop to scan the control module with a diagnostic tool. Ignoring it for too long could lead to more severe engine damage. Safety first—remember to steady the steering wheel and pull over if the car stalls.
