Two problems related to automatic transmission control module have been reported for the 2014 Nissan Sentra. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2014 Nissan Sentra based on all problems reported for the 2014 Sentra.
The continuously variable transmission (cvt) on my 2014 Nissan Sentra has failed twice. First failure: in August 2018, at 42,429 miles, the car hesitated and jerked when accelerating. Walser Nissan wayzata (invoice [xxx]) found an internal cvt failure with excessive debris and bearing parts on the magnets. Nissan replaced the cvt under warranty with a remanufactured unit (part 3102m-x428ere) and reprogrammed the tcm. Second failure: around [xxx], at about 110,000 miles, in minnetonka, mn, the replacement cvt began stuttering while the car was being driven at about 30 mph, then lost drive power completely. The car had to be towed and cannot be driven. This was only about 67,000 miles after Nissan installed the replacement unit. No crash or injuries. Safety concern: a sudden loss of drive power while moving in traffic creates a risk of a rear-end crash or being stranded in a dangerous spot. The Nissan-supplied replacement failed the same way as the original, which points to a continuing defect, not a one-time problem. The car was maintained on schedule with service at Nissan dealerships. I reported this to Nissan (case [xxx]) and Nissan refused to help. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
The transmission would occasionally slip while in motion during acceleration. When the vehicle was brought into the dealer for an oil change, we brought the issue to their attention. Service department advised that a tcm software update was needed. I located a service campaign bulletin covering tcm reprogram covering 2013 vehicles (sb-10051662-4475). Nissan consumer affairs will not address the 2014 issue at this time.
