2015 Nissan Sentra

The contact owns a 2015 Nissan Sentra. The contact stated while driving 30 MPH and depressing the accelerator pedal, the vehicle failed to respond. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was not repaired. The contact related the failure to TECHNICAL SERVICE BULLETIN: 10058388 (Transmission Control Module); however, the vehicle was not included in the TSB. The manufacturer was not notified of the failure. The failure mileage was 111,000.

The contact owns a 2015 Nissan Sentra. The contact stated that on several occasions while stopped at a traffic light, the vehicle unintendedly accelerated. There was no warning light illuminated. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the failure might have been caused by an Oxygen sensor failure. The Oxygen sensor was replaced; however, the failure persisted. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 65,000.

The contact owns a 2015 Nissan Sentra. The contact stated while driving at an undisclosed speed, the vehicle downshifted with the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the transmission failed and needed to be replaced. The vehicle was repaired but the failure recurred. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 240,000.

The contact owns a 2015 Nissan Sentra. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. In addition, the vehicle jerked, and the contact noticed an abnormally loud sound. The vehicle was taken to an independent mechanic where it was diagnosed CVT failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The dealer was made aware of the failure. The contact referenced an undisclosed recall; however, the VIN was not included in the recall repair. The dealer advised the contact to contact the NHTSA Hotline to report the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.

This particular vehicle exhibits a very strong, almost dash rattling judder when moving from the 1st to 2nd gearing ratio. This is especially dangerous in traffic and intersections where the vehicle is known to be in 1st or 2nd gear ratio, as Nissan likes to ratio out their CVT in software through the TCM to produce what feels like shifting from gear-to-gear as in a normal automatic transaxle. What makes this situation extremely bad is that when entering an on-ramp to the interstate (I-20 for example) it will intermittently judder from 1st to 2nd and then no power. After the judder it takes another few seconds for the TCM to figure out what happened and engage maybe more valve body pressure? I'm not sure completely, but it's extremely unsafe to drive. The Altima/Rogue with the same transaxle and model year run was issued a TSB and subsequently a TCM update was issued to rectify the early shudder, but the Sentra did not receive that update. The TCM output data shows that when this shudder is happening that there is a loss in hydraulic pressure somewhere in the unit. As Nissan says you never are supposed to change the fluid, this creates a very serious issue not only with the transmission, but warranty as well. The safety risk to others is high on this one because this could cause major rear-end conditions and city driving collisions as the car is supposed to be accelerating but can't because the transaxle was slipping and not gaining speed with the rest of the vehicles as expected.

The contact owns a 2015 Nissan Sentra. The contact stated while driving 60 MPH, the vehicle began jerking and lost motive power. The vehicle was steered into a parking lot and restarted. The vehicle was then towed to the residence. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 85,000.
