NHTSA Complaint #10734667 — 2015 NISSAN PATHFINDER

POTENTIALLY FAULTY BRAKE SYSTEM OR DOWNSHIFT CVT OR SIMULATED GEARSHIFT SYSTEM. DETAILS: WHEN DRIVING IN SLOW MOVING TRAFFIC WITH THE BRAKES PARTIALLY APPLIED, THE VEHICLE TENDS TO MOMENTARILY ACCELERATE AND SPEED UP. CONCURRENTLY THE RESISTANCE ON THE BRAKE PEDAL TENDS TO DECREASE, ALONG WITH A VISIBLE DOWN-AND-THEN-BACK-UP JUMPING OF RPM NEEDLE. THE BRAKE PEDAL NEEDS TO BE KEPT PRESSED TO ALLOW THE VEHICLE TO SLOW DOWN. TOOK VEHICLE TO DEALERSHIP (NEW VEHICLE, WITH ONLY 300 MILES), THE TECHNICIAN NOTICED THE PROBLEM I HAD BEEN EXPLAINING. THE TECHNICIAN AGREED TO SPEAK WITH THE ENGINEER THE NEXT DAY. HOWEVER, NEXT DAY THE DEALERSHIP STATED THAT THEY HAVE NEVER ENCOUNTERED SUCH AS ISSUE, AND IT MAY BE SIMPLY THE DOWN-SHIFT OF THE CVT TRANSMISSION. THIS IS UNUSUAL IN COMPARISON TO ANY OTHER CAR I HAVE DRIVEN. ACCELERATION OF THE CAR DURING THE BRAKING CYCLE IS CLEARLY ODD. POTENTIALLY DANGEROUS SITUATION WHEN APPROACHING A STOP SIGN OR SLOW TRAFFIC ZONES NEAR SCHOOLS. PLEASE INVESTIGATE.
