2017 Nissan Armada Power Train

The contact owns a 2017 Nissan Armada. The contact stated that while driving at low rates of speed, the vehicle came to an abrupt stop with the check engine and ABS warning lights illuminated. The contact was forced to restart the vehicle; however, the vehicle failed to accelerate above 30 MPH. The vehicle was taken to a dealer where the contact was initially informed that the output speed sensor was defective; however, later the contact was informed that the transmission needed to be replaced. The manufacturer was notified of the failure and a case was filed. The vehicle was not yet repaired and remained in the possession of the dealer. The failure mileage was approximately 55,000.

My driver's side rear "CV axel" needs replaced, and there are many TSB's regarding the Powertrain. My vehicle has roughly 87,000 miles on it. It seems as if there is an issue the manufacturer knows about but there hasn't been enough complaints as of yet.

The contact owns a 2017 Nissan Armada. The contact stated that while driving 30-40 MPH, she noticed increased friction on the tires, and they were not rotating properly. There were no warning lights illuminated. The contact veered to the side of the road, turned off the vehicle, and restarted it. The contact was able to continue to drive the vehicle with no issues; however, the failure reoccurred. The contact stated that she noticed that the rear tires were significantly close to the top of the wheel well. The vehicle was taken to the dealer but was not diagnosed. The contact stated that the failure had been reoccurring while driving. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The approximate failure mileage was 79,000.

THE VEHICLE ABRUPTLY LOST REVERSE GEAR WHILE DRIVING ON A PUBLIC ROADWAY. AFTER APPROXIMATELY 3 HOURS OF CONTINUOUS HIGHWAY DRIVING, THE VEHICLE WAS BROUGHT TO A STOP, PLACED INTO REVERSE, ACCELERATED IN REVERSE FOR APPROXIMATELY 100', AND SHIFTED BACK TO DRIVE. AFTER SUBSEQUENTLY COMING TO A STOP, OPERATOR ATTEMPTED TO PUT THE VEHICLE IN REVERSE AGAIN BUT VEHICLE FAILED TO ENGAGE THE REVERSE GEAR. IN FACT THE VEHICLE WAS ESSENTIALLY IN NEUTRAL DESPITE THE GEAR SHIFTER INDICATING 'R' GEAR. AGAIN, THE GEAR SHIFTER WOULD READILY SHIFT TO 'R' BUT IN FACT NO GEAR WAS APPARENTLY ENGAGED AS THE VEHICLE WOULD ROLL DOWNHILL AS IF IT WERE IN NUETRAL. VEHICLE FAILED TO PROCEED IN REVERSE DESPITE OPENING THE THROTTLE (I.E. 'GIVING IT GAS'). AS FAR AS WE COULD TELL THE VEHICLE WAS ABLE TO SHIFT TO PARK AND DRIVE. THE VEHICLE WAS ABLE TO PROCEED IN DRIVE. NO EXCESSIVE NOISES OR VIBRATIONS WERE EXPERIENCED THROUGHOUT THE DURATION OF THIS INCIDENT. OWNER CALLED LOCAL NISSAN DEALERSHIP TO REPORT THE TROUBLE AND LATER DELIVERED VEHICLE TO DEALERSHIP. DEALERSHIP ADVISED THAT IT HAD CONTACTED NISSAN ENGINEERING HOTLINE FOR DIRECTION HOW TO PROCEED. DEALERSHIP STATED NISSAN ENGINEERING HOTLINE ADVISED REPLACEMENT OF TRANSMISSION. NISSAN CONSUMER AFFAIRS REFUSED TO PROVIDE ANY ASSISTANCE OR CONSIDERATION TO CUSTOMER EXCEPT TO RELY UPON EXTENDED WARRANTY PURCHASED BY CUSTOMER AT ORIGINAL SALES TRANSACTION. DEALERSHIP STATED ALL LABOR AND MATERIAL WERE COVERED BY WARRANTY. THIS 4 YEAR OLD NISSAN SUV HAS ONLY 1 ORIGINAL OWNER, HAS KEPT UP WITH ALL SCHEDULED MAINTENANCE PERFORMED BY NISSAN DEALERSHIP, AND HAS OPERATED FOR FEWER THAN 10,000 MILES PER YEAR. APPROXIMATE MILEAGE AT INCIDENT IS 38,200 MILES. ACCORDING TO THE DEALERSHIP THE MAKE AND MODEL OF THE REPLACEMENT TRANSMISSION IS JATCO CORP. RE7R01B X100A.

THE TRANSMISSION IS SHIFTING INCORRECTLY AT LOW RPMS. I CAN CLEARLY SEE THE RPM FLUCTUATING ESPECIALLY GOING UPHILL. THIS HAPPENS 30-50 MPH.LACK OF POWER/ACCELERATION. FEELS LIKE TRANSMISSION IS SHIFTING IN LOWER GEARS TOO SOONER AND AND WON'T ACCELERATE UNTIL DRIVER PUSHES SIGNIFICANTLY. THIS IS VERY DANGEROUS ESPECIALLY MAKING TURNS AT STOP LIGHTS.

THE TRANSMISSION ON MY 2017 ARMADA SEEMS TO SHIFT IMPROPERLY AND EVEN SEEMS TO SHIFT PREMATURELY CAUSING A STALL OR LOSS OF POWER TO THE VEHICLE. I'VE NOTICE THIS AS I'M STARTING TO ACCELERATE FROM A STOPPED POSITION AND IT APPEARS TO HAPPEN SOMETIME BETWEEN SHIFTING FROM 2ND TO 3RD GEAR. THIS HAPPENS ALL THE TIME WHILE DRIVING IN TOWN, ON THE HIGHWAY, I'VE YET TO NOTICE ANY ISSUES. I PURCHASED THIS VEHICLE USED FROM BUICK/GMC IN GILROY, CA. AUGUST OF 2019. I FAILED TO NOTICE THIS ISSUE WHEN I TEST DROVE THE VEHICLE.

THE NEW ARMADA FOR 2017 HAS A COLD WEATHER PROBLEM IN ITS TRANSMISSION. THE PROBLEM IS IT DOESN'T SHIFT PROPERLY. MY DEALER SAYS THAT'S THE WAY IT SUPPOSED TO WORK TO WARM THE FLUID. BUT IN THE 40 YEARS THAT I HAVE BEEN DRIVING COLD WEATHER HAS NEVER BEEN A PROBLEM FOR TRANSMISSIONS. IT STAYS IN 2ND AND 3RD GEARS WAY TO LONG . ANYWAY THAT'S MY PROBLEM AND THERE SHOULD BE A SOLUTION, MAYBE A DIFFERENT TRANSMISSION FLUID OR A DIFFERENT CODE TO SHIFT MORE QUICKLY. AN UPDATES NEEDED. THIS HAPPENS EVERYTIME YOU START FROM A STOP UNTIL THE CAR WARMS, ABOUT 20 MINUTES OF DRIVING. NISSAN MILEAGE COULD GO UP AN ADDITIONAL 2 MILES PER GALLON MORE IF IT DIDN'T HAVE SUCH HIGH REVS DURING THIS WARM UP PERIOD.

WHILE DRIVING, THE TRANSMISSION HUNTS AND SHIFTS VERY EARLY, CRIPPLING ACCELERATION. AT NORMAL HIGHWAY SPEEDS, SIGNIFICANT DEPRESSION OF THE ACCELERATOR IS REQUIRED TO EFFECT A DOWNSHIFT. THIS PRESENTS A SAFETY HAZARD WHEN ACCELERATION IS REQUIRED FOR MANEUVERING. WHEN THE VEHICLE DOES SHIFT INTO THE NEXT GEAR, SIGNIFICANT OSCILLATIONS OCCUR UNTIL THE TRANSMISSION SETTLES ON A POINT. ALSO, AT HIGHWAY SPEED, THE ENGINE RPM CONTINUOUSLY 'FLUTTERS' UNDER CONSTANT ACCELERATOR POSITION AND NO CHANGE IN ENGINE LOAD (FLAT STRAIGHT ROAD). I HAVE ALSO NOTICED THAT WHEN I SLIGHTLY DEPRESS THE ACCCELERATOR TO MAINTAIN SPEED, THE TRANSMISSION RESPONDS BY FURTHER REDUCING ENGINE RPM AGAIN HAMPERING ACCELERATION (EXACTLY OPPOSITE OF ANY OTHER AUTOMATIC VEHICLE I HAVE DRIVEN). THIS TRANSMISSION OPERATES AS IF IT HAS AIR IN THE HYDRAULICS. I HAVE HAD THE LATEST TSB INSTALLED FOR THE ECM AND TCM (REVISION E). NISSAN DOES NOT APPEAR TO BE CAPABLE OF FIXING THIS SAFETY ISSUE.

SOMETIMES WHEN PRESSING THE ACCELERATOR, THE VEHICLE WILL ACT LIKE IT IS TRYING TO CHOKE OUT AND WILL SHUDDER AND/OR HESITATE. THIS CAN OCCUR WHEN TRYING TO CLIMB AN INCLINE OR WHEN MERGING INTO TRAFFIC FROM A SLOWED DOWN OR STOPPED STANDING. THIS CAN BE SEEN IN A SHUDDER IN THE TACHOMETER NEEDLE AND FEELS TERRIBLE. THERE IS GREAT CONCERN ON MY PART THAT IT WILL HAPPEN TO DO THIS AT A MOMENT THAT MY CHILDREN ARE WITH ME AND WILL CAUSE ME TO BE HIT BY ANOTHER VEHICLE. THE OCCURRENCE IS UNPREDICTABLE BUT IS INCREDIBLY NOTICEABLE. I HAVE BEEN TOLD BY THE DEALERSHIP MANY TIMES THAT THIS IS NORMAL AND THAT NO ONE ELSE HAS REPORTED A PROBLEM. I CANNOT IMAGINE THAT ANYONE WOULD BUY THIS VEHICLE GIVEN HOW EASILY THE PROBLEM IS NOTICED. IT IS UNNERVING.

FROM SLOW STARTS, THE TACHOMETER WILL FLUTTER AND THAT HESITATION IS TRANSMITTED THROUGH THE DRIVETRAIN TO THE WHEELS. THIS HESITATION HAS BEEN SEEN AROUND ALL SHIFT POINTS AND HAS BEEN CONFIRMED BY SERVICE TECHNICIANS. NISSAN DOES NOT HAVE A FIXED AT THIS TIME. THE CONDITION REPRESENTS A HAZARD ON ICY ROADS' IT CAUSED ME TO LEAVE A LANE DUE TO SLIP. A VIDEO OF THE TACHOMETER IS AVAILABLE ON REQUEST.

THE TRANSMISSION DOES NOT SEEM TO SHIFT IN A NORMAL MANNER IT DOES NOT SHIFT UP WHEN STARTING FROM A STOPPED POSITION AND SEEMS TO DOWNSHIFT UN-NECESSARILY. YOU CAN HEAR THE ENGINE WORKING HARDER THAN IT SHOULD SINCE IT'S IN A LOWER GEAR THAN IT SHOULD BE, AND YOU CAN SEE IT IN THE TACHOMETER BECAUSE IT'S RUNNING AT A MUCH HIGHER RATE. ON ONE OCCASION I NOTICED THE TACHOMETER FLUTTERING FOR 10-15 SECONDS WHILE DRIVING AT A STEADY SPEED. ALL OF THE OCCURRENCES WERE ON CITY STREETS. THE PROBLEM DOES NOT HAPPEN ALL OF THE TIME AS IT COULD BE A FEW DAYS IN BETWEEN OCCURRENCES. I HAVE BEEN TO THE DEALER TWICE ALREADY. THEY DID NOTICE THE PROBLEM AND UPDATED THE SOFTWARE, BUT THE PROBLEM STILL EXISTS. THEY CLAIM THEY DO NOT HAVE A FIX!
