While problematic car infotainment systems continue to be among the top issues reported by new car owners, Consumer Reports has identified an emerging trend of increased troubles with new transmission systems developed to improve fuel economy.
The recently launched Jeep Cherokee has had persistent problems with its nine-speed automatic transmission. Despite several rounds of software updates, complaints of rough shifting or getting stuck in one gear continue. The six-speed dual-clutch transmissions also created problems for the Dodge Dart and Fiat 500L.
Nine-speed automatic and eight-speed dual-clutch transmissions are responsible for many of the problems reported in the new Acura TLX—key toward knocking the brand into below-average reliability.
Even Nissan, which has been using continuously variable transmissions (CVT) for awhile, has been plagued by issues with the new CVT introduced on the redesigned Pathfinder and Altima.
