What is the situation with the Nissan Qashqai transmission oil leak?
2 Answers
Nissan Qashqai transmission oil leak reasons are: 1. Oil seal aging or cracking; 2. Incomplete sealing at the transmission joint position; 3. Transmission housing damage. The function of the transmission is: to change the transmission ratio to expand the range of changes in the driving wheel torque and speed, adapt to frequently changing driving conditions, and allow the engine to operate under favorable working conditions. Taking the 2021 Nissan Qashqai as an example, its body dimensions are: length 4401mm, width 1837mm, height 1593mm, wheelbase 2646mm, minimum ground clearance 181mm, and body weight 1444kg.
Over the years repairing cars, I've encountered quite a few cases of oil leakage from the Qashqai's transmission. The main causes are aging or damaged oil seals - the transmission's oil seals tend to crack and leak after prolonged use. Additionally, the transmission housing at the bottom might crack due to road bumps or being hit by small stones. If not addressed promptly, complete oil loss can lead to internal transmission wear or even burnout, making repairs much more expensive and complicated. When you notice oil stains on the ground or smell burning, I recommend immediately checking the transmission fluid level using the dipstick to see if it's low. It's best to take it to a professional repair shop - simply replacing the oil seals or repairing the housing usually costs just a few hundred yuan. Don't wait until the problem worsens to get it fixed.
