2014 Nissan Sentra recalls and problems

In May 2016, Nissan North America issued a safety recall (16V-244) to address the problem of improper classification of adult front seat passengers in approximately 3.3 million vehicles, including those in the scope of this investigation when it was opened (almost one million vehicles) and additional vehicles, as shown below.Nissan models: certain model year 2013-2016 Altima, 2013-2016 LEAF, 2016-2017 Maxima, 2015-016 Murano and Murano Hybrid, 2013-2016 Pathfinder, 2014-2015 Pathfinder Hybrid, 2014-2017 Rogue, 2013-2016 Sentra, 2013-2016 NV200, and 2014-2016 Taxi.Infiniti models: certain model year 2013 JX35, 2014-2017 Q50, 2014-2016 Q50 Hybrid, and 2014-2016 QX60 and QX60 Hybrid.Chevrolet model: certain model year 2015-2016 City Express.Additional information on the above-referenced recalls is available online at NHTSA.gov.Also, the numbers shown in the above failure report summary are for the original vehicle population, as opposed to the entire recall population, and the ODI reports cited are as of May 31, 2016 when Nissan began to notify the affected owners of recall 16V-244.Based on the recall actions taken by Nissan, this Engineering Analysis is closed.Additional information on this closing resume and the investigation are in the EA15-004 public file available online at NHTSA.gov.The ODI reports cited above can be reviewed online at https://www.nhtsa.gov/recalls#vehicle under the following identification numbers: 10583283 10585264 10585349 10585379 10592434 10593399 105…

In April 2014, Nissan North America launched Safety Recall 14V-138 to address problems with the Occupant Classification System (OCS) algorithm in the following vehicles: model year (MY) 2013-2014 Nissan Altima, Pathfinder, Sentra and LEAF; MY 2013 Infiniti JX35; MY 2014 Infiniti QX60 and Q50; and MY 2013 Nissan NV 200/Taxi vehicles.According to Nissan, the OCS may misclassify adult front passenger occupants and turn off the passenger's frontal air bag for an adult occupant of sufficient weight.In March 2015, the Office of Defects Investigation (ODI) opened this Recall Query after the agency received approximately 124 complaints alleging problems with the OCS after the recall repairs and/or other OCS related repairs were made by Nissan/Infiniti dealers.The majority of the complaints alleged the passenger air bag status light stays on (i.e., indicating passenger air bag is turned off) for adult front passengers of sufficient weight.Many of the complaints stated the dealers have made multiple repairs but the problem still persists.In its June 2015 response to ODI's information request under the Recall Query, Nissan provided approximately 1,121 complaints and field reports on the recalled vehicles.These reports alleged OCS issues similar to the NHTSA reports described above.At this time, NHTSA has received a total of approximately 208 complaints (note: total of 1,271 reports shown in the table above eliminates 58 duplicative reports received by ODI and manufacturer).This Recall Q…

On May 20, 2014, ODI opened PE14-014 based on eight complaints alleging incidents of excessive brake pedal travel in model year (MY) 2013 through 2014 Nissan Sentra, Versa Sedan and Versa Note passenger cars (Figure 1) and information in Early Warning Reporting field reports indicating issues with master cylinder internal seals.In response to an information request letter sent by ODI, Nissan identified a condition with the master cylinder in early production subject vehicles that could result in a slow internal leak past one of the recuperating seals to the brake reservoir when the brake pedal is depressed very slowly or lightly (Figure 2).The subject vehicles are equipped with fixed seal master cylinders supplied by TRW.To address concerns with water hammer noise with the standard seal design, the master cylinders in the early production subject vehicles used AWH (anti-water hammer) seals.The AWH seals are sensitive to contamination from assembly plant cleanliness issues, which can produce the internal leak condition during slow or light brake applies but perform as designed with normal or emergency brake applications.TRW indicated that the risk of contamination interacting with the subject seals is greatest after the evacuation and pressure fill process used to fill the brake system during the manufacturing process (early life issue).TRW developed a new master cylinder seal design (EVO seal) that addresses the noise concern and eliminates the internal leak concern associate…
