The Qashqai transmission is not prone to failure. Below is relevant information about the transmission: Main functions: Changing the transmission ratio to expand the range of torque and speed variations of the driving wheels, adapting to frequently changing driving conditions while allowing the engine to operate under favorable conditions. Enabling the vehicle to reverse while maintaining the engine's rotational direction; utilizing neutral gear to interrupt power transmission, allowing the engine to start, shift, and facilitating gear changes or power output. Working principle: Manual transmissions primarily consist of gears and shafts, achieving speed and torque variations through different gear combinations; whereas automatic transmissions (AT) are composed of torque converters, planetary gears, and hydraulic control systems, achieving speed and torque variations through hydraulic transmission and gear combinations.

Last time on a long-distance trip, I chatted with a Qashqai owner whose 2016 model had a major transmission overhaul at just 80,000 km. These early CVT7 models indeed had issues, particularly with cold-start chain slippage and noticeable low-speed jerking. The 4S shop technician said it was mainly due to poor transmission fluid temperature control and the valve body being prone to carbon buildup. However, after the 2018 model refresh with new steel belts and oil circuit design, complaints have significantly decreased. Owners of older models should pay attention to frequent transmission fluid changes and avoid using low-quality oil.

My cousin has been working in a used car dealership for five or six years and has handled over thirty X-Trails. He clearly stated that second-hand X-Trails from the 2014-2016 models must be approached with caution, as three or four out of ten have had their transmissions repaired. However, the failure rate of the improved models after 2017 has decreased significantly. When purchasing, he actually prefers the third-generation models from 2019 onwards, as they generally only exhibit normal wear and tear with minimal issues.

Checked the data on the car quality website, and it's quite interesting: the number of transmission complaints for the Qashqai was concentrated around the 2015 batches, with over 500 cases of vibration and noise complaints that year alone. However, after the new Qashqai started using the newly developed Jatco CVT8 transmission, the number of complaints dropped to just over 30 cases last year. What's more concerning now are those aggressive drivers—the belt slipping during rapid acceleration really damages the transmission.
