Currently, the issues with the updated transmission are not significant, with only occasional reports of unusual noises, which are not a common problem for the transmission. Therefore, Teana owners need not worry excessively. However, the CVT continuously variable transmission does have certain drawbacks, such as a lower torque capacity, making it unsuitable for heavy loads or extreme driving conditions, and its service life is somewhat shorter compared to conventional automatic transmissions. Below is an introduction to the Nissan Teana: 1. Exterior: The 2021 Teana introduces new red-black and white-black dual-tone exterior options. Except for the base 2.0L model, all variants come equipped with 17-inch or larger wheels, LED headlights, and LED daytime running lights. Additionally, the model offers a Midnight Edition package, featuring darkened emblems, chrome front grille accents, wheels, rear spoiler, and a Midnight emblem for a distinctive appearance. 2. Interior: The 2021 Teana's upgrade includes piano black door trims, wood grain accents on the dashboard and gear shift console, and premium soft-touch materials to enhance cabin luxury. The Midnight Edition also comes with luxurious LED welcome sills and exclusive floor mats. 3. Powertrain: The 2021 Teana offers a 2.0L naturally aspirated engine and a 2.0T turbocharged engine, paired with the new intelligent XTRONIC CVT transmission that provides a gear range equivalent to an 8-speed automatic. The 2.0T variant features the VC-TURBO variable compression ratio turbocharged engine, which intelligently adjusts the compression ratio between 8:1 (high performance) and 14:1 (high efficiency). The 2021 Teana accelerates from 0-100 km/h in just 6.42 seconds, with a minimum fuel consumption of 6.6L per 100 km.

I've driven a Teana for 8 years with 150,000 kilometers on the odometer, and the transmission has never had any issues. This matter should be viewed objectively. The early models from 2009-2012 did have CVT overheating protection issues that would limit power after prolonged high-speed driving. However, the cooling system was improved after the 13th generation, and the 2017 model even upgraded the steel belt material. In our car owners' group, new owners rarely complain about it. Remember, changing the transmission fluid every 40,000 kilometers is crucial—many problems arise because people skip maintenance to save money. While Nissan's CVT may not be as rugged as Toyota or Honda's, as long as you don't race or tow heavy loads, it can easily handle 200,000 kilometers of city driving without issues.

Having worked in a repair shop for ten years, I've serviced dozens of Nissan Teana transmissions. The most common issues encountered are solenoid valve failures and steel belt slippage, especially noticeable jerking after 100,000 kilometers. To be honest, these problems are frequently seen in taxis or vehicles subjected to aggressive driving. Well-maintained family cars rarely exhibit such issues, though I've observed higher CVT failure rates in Nissan Sylphys. Teana transmission repairs can be costly, with a complete replacement costing over 10,000 RMB, but aftermarket valve bodies now available for just over 1,000 RMB can effectively address jerking problems. My recommendation is to drive worry-free for the first five years with a new car, then regularly check the transmission fluid condition thereafter.

Having followed Japanese B-segment sedans for years, the topic of the Altima's transmission has always been a hot one. J.D. Power reports indicate its failure rate is 17% higher than the Camry's, but lower than American cars. Issues mainly focus on cold-start noises in frigid regions, while southern owners tend to care less. Nissan's CVT tuning leans toward comfort, with its slightly delayed response during sudden acceleration often mistaken for malfunction. For those prioritizing durability, the 2.0T paired with a 9AT would be a better choice. Recently helped a friend shop for a used Altima, deliberately avoiding the older 2012 and 2014 models.
