Why is the Nissan Qashqai not accelerating when pressing the accelerator?
2 Answers
The reason why the Nissan Qashqai is not accelerating when pressing the accelerator is due to clutch slippage. Below are the specific details: 1. Manifestation: Clutch slippage mainly manifests as the vehicle's speed not increasing with the rise in engine RPM during acceleration, resulting in the engine's power not being fully transmitted to the drive wheels, causing weak driving performance, especially noticeable when going uphill. 2. Causes: The main reasons for clutch slippage include insufficient friction of the clutch friction plate; shifting gears too early or disengaging gears before the clutch is fully engaged; prolonged driving with the clutch partially engaged or coasting with the clutch pedal depressed; and abnormal wear of the clutch plate caused by abruptly pressing the accelerator when the gear is not fully engaged or disengaged.
When I first started driving the Qashqai, I also encountered the problem of the car not accelerating properly when stepping on the gas, which was really frustrating. At first, I thought it might be a loose connection in the throttle pedal or a faulty sensor, as pressing it didn’t seem to have any effect. Later, the mechanic found out that the engine throttle body was clogged with too much carbon buildup, restricting airflow and causing a lack of power—regular cleaning was necessary. The fuel system could also be a culprit, such as an underperforming fuel pump or clogged fuel injectors, affecting the quality of the air-fuel mixture. For the transmission, if the automatic gearbox has high oil temperature or the clutch is slipping, power delivery gets stuck. I recommend not rushing to drive it out—first, check the dashboard lights, like whether the engine warning light is on. A simple fix is to try replacing the air filter. If that doesn’t work, contact a repair shop immediately. Safety first—don’t risk having issues on the road.
