2018 Nissan Leaf

I did not have an incident(accident), I noticed issues with my car, that seem to be prevalent with other Nissan Vehicles. This report is mostly proactive. I took the vehicle to the dealer for inspection and repair however was unable to come to a conclusion due to multiple inspection charges done by dealer but no fixes. Issue 1. Airbag Fault Warning Light on the dash. Turns on when I start the car, and stays. I took car to dealer and they have done a computer reset to reset the light (based on an internal Nissan bulletin on how to repair that issue, with mention in the repair notes that a lot of vehicles have that issue.) The reset didnt work and the light is back, now the dealer is saying that a whole sensor needs replacing as its prone to failure. Initial repair mentioned "code B00A0 stored for occupant detection system, but will not relearn." Zero Point Relearn will not complete. Referred to NTB19-071D... Ran the 75H Reset, code clears." Secondary repair: 'B00A0 Returned. Performed database search and found similar cases. Nissan recommends OSC and sensor replacement. Performed Bulletin again and error code is now 24H, not 75H. Zero point will not relearn. Started a case with Nissan and was advised to replace ...[OCS]... and strain sensors..." Issue 2: Loud clanking or grinding noise when turning vehicle left or right until wheel stops. Went to get this repaired and was told that dealer found bulletin 12-055J and will "need to replace axle nuts and apply Molykote." Paid for repair, and after picking up the car the sound is even worse, and upon bringing it back the dealer is saying that the noise is not due to past repair but vehicle will now need "Both front Strut mounts and bearings replaced." The sound is the same, and a cursory online search shows that this issue is prevalent across multiple vehicles. Also, recently when attempting a U-turn, the steering locked up momentarily when I was trying to straighten out the vehicle, with that noise (clunk sound)

NISSAN PROPILOT HAS A SERIOUS SAFETY FLAW. WHEN USING PROPILOT ON MY 2018 NISSAN LEAF SV IN STOP AND GO HIGHWAY TRAFFIC, SOMETIMES WHEN MY NISSAN LEAF COASTS TO AN ALMOST COMPLETE STOP 15 FEET BEHIND A "BOXY" VEHICLE LIKE A SEMI-TRUCK, THE LEAF SUDDENLY ACCELERATES LIKE IF THERE IS NO VEHICLE DIRECTLY IN FRONT OF ME AND IF I AM NOT COMPLETELY ATTENTIVE AND IF I DO NOT IMMEDIATELY APPLY THE BREAKS, THE NISSAN LEAF WOULD REAR END THE SEMI-TRUCK. THIS HAS HAPPENED TO ME 4 TIMES OVER THE PAST 6 MONTHS WHEN FOLLOWING A SEMI-TRUCK WITH TRAILER AND THIS MORNING IT OCCURRED AGAIN A FIFTH TIME BUT THIS TIME I WAS BEHIND A SEDAN. I HAVE A DASHCAM VIDEO OF THE INCIDENT FROM THIS MORNING. I HAVE REPORTED THIS ISSUE TO NISSAN BUT THEY HAVE DONE NOTHING ABOUT IT. I HAVE TAKEN MY 2018 NISSAN LEAF IN TO THE LOCAL NISSAN SERVICE CENTER BUT THEY SAY THERE IS NOTHING WRONG WITH THE SENSORS AND THEY DO NOT SEE ANY ISSUES AND NO ERROR CODES REPORTED BY THE CAR. I BELIEVE THIS IS A SOFTWARE PROBLEM WHERE THE SOFTWARE IGNORES THE RADAR IMAGE OF THE TRUCK IN FRONT BECAUSE IT THINKS IT IS AN OVERHEAD SIGN AND NOT ANOTHER VEHICLE IMMEDIATELY IN FRONT, THE CAMERA INPUT OF THE VEHICLE IN FRONT ALSO APPEARS TO BE IGNORED BY THE SOFTWARE IN THIS SITUATION. ADDITIONALLY, I HAVE HAD AT LEAST TWO INCIDENTS (ALSO OCCURRED THIS MORNING) WHERE PROPILOT LANE KEEPING FEATURE SHUTS OFF AND AUTOMATIC EMERGENCY BREAKING IS ALSO SHUT OFF AND DEACTIVATED FOR AND EXTENDED PERIOD OF TIME FOR NOW APPARENT REASON (IN EXCELLENT WEATHER AND CLEAR CONDITIONS, NO OBSTRUCTIONS OF SENSORS, ETC.), I HAVE VIDEO OF THIS AS WELL.

THIS NISSAN CAR IS EQUIPPED WITH FEATURES NAMED, PRO-PILOT ASSIST (PPA), INTELLIGENT CRUISE CONTROL (ICC) AND EMERGENCY BRAKE ASSIST (EBA). WHEN ENGAGED, IT IS SUPPOSED TO KEEP LANES AND FOLLOW DISTANCE IF THERE IS A CAR IN FRONT. WHEN THE CAR IN FRONT IS STOPPED THIS CAR IS SUPPOSED TO STOP AS WELL. PPA WHEN ENGAGED, IF THERE ARE GOOD ROAD MARKINGS, WILL SHOW A GREEN STEARING ON THE DASH BOARD, TO SHOW THAT CAR CAN STEER IT SELF. HOWEVER IF THERE IS A CAR STOPPED IN FRONT ON THE SAME LANE (EX. STOPPED FOR A RED LIGHT), THIS CAR DO NOT DETECT THAT THERE IS A CAR STOPPED, AND KEEP GOING FORWARD UNTIL CRASH INTO THE STOPPED CAR, DRIVER HAVE TO INTEVENE TO STOP AT THIS TIME TO STOP. I TOOK CAR TO DEALER AND THEY SAID THIS IS NORMAL. THAT IS NOT WHAT NISSAN ADVERTISE. THIS BEHAVIOR IS QUITE DANGEROUS OF THESE CARS, AND MY EXPECTATION IS THE CAR NEED TO STOP IF THERE IS AN OBSTRUCTION IN THE ROAD, WHEN THE GREEN STEERING WHEEL ON DASH IS SHOWING THAT CAR IS DOING AUTO-STEER.
