2020 Nissan Murano Driver Assist & ADAS Problems

The car keeps braking like I've been in an accident when I travel under an overpass. It doesn't do it every time, just sometimes. I've had it at the dealer, Don Moore in Owensboro, Ky. and since it doesn't show any codes they can't/won't do anything about it. I don't feel safe driving this car for fear it will slam on the brakes at any time. It has happened 3 times so far. It also did it almost, once, when driving down the main street in town. It all of the sudden showed the cameras and the lights came up on the dash but luckily it didn't brake. Thank you. [XXX] .

The forward collision warning is stuck on saying malfunction. Sometimes the car brakes without warning, activating the automatic emergency braking and stopping suddenly. This is dangerous.

While driving down interstate the car's automatic collision breaking system activated and brought the car to an immediate stop. While breaking the information screen in the steering wheel area flashed red with an explanation point symbol but as soon as the breaking was done it went away and no other lights appeared on the dash indicating an issue. There was nothing that should have triggered the automatic collision braking system to have engaged. Had someone been directly behind me this could have easily caused an accident by them slamming into the back of my car as nothing would have caused them to expect sudden breaking by me. The unexpected sudden breaking happened twice within a 10 minute window while driving on interstate. I have driven it minimally since so I could have it looked at by the dealer to review the issue as it is under warranty and I felt it unsafe to drive. The car has been inspected by a Nissan dealer and they are unable to reproduce the issue and are not taking any repair action at this time.

Vehicle routinely triggers the automatic emergency braking system when approaching a certain overpass. Speeds are usually around 40 to 50 MPH. Occasionally triggers at other locations where no obstacle should be triggering it. Local Nissan dealer has inspected the system several times, including sending to a specialist, and found no defect.

Yesterday, my wife and I were on I94 eastbound in heavy afternoon traffic, in the left of three lanes, and crossed from Minnesota into Wisconsin. The car was on interactive cruise control. The freeway entry to Wisconsin is a long, uphill grade and I needed to get out of the left lane in preparation to exit about 3 miles ahead. I turned off the interactive cruise control and pressed the accelerator in order to safely merge into the faster moving center lane. I instantly lost control of the engine. Not only did the engine not respond to pressing the accelerator, it actually bogged down and slowed. Having effectively lost power because I had no control over the engine, I tried to shelter on the left shoulder but is was not wide enough to get the car out of the left lane. Worse, the narrow shoulder between the left lane and the concrete barrier wall was full of debris, and I immediately had a terrible fear of puncturing a tire in which case I would really be in trouble. The car came to a stop and I still had no control over the engine, sitting there with high speed traffic swerving around us. I put the transmission in neutral and it still didn’t respond to the throttle, and the same with park. Finally, I stopped the engine and restarted, and I then had control of the car. When a gap in traffic came, I got back on the freeway and continued home with no further incident. I could easily have been hit by a high speed vehicle, or caused a severe accident involving others due to vehicles unexpectedly finding us stopped, and still partially in the left lane. The car will go to the dealer next week. I was so terrified that I do not know if there were warning lights lit on the dash, but I didn't see any.

WE'VE HAD THE VEHICLE OVER A YEAR AND HAVE NEVER BEEN ABLE TO GET USED TO THE FORWARD AND BACKWARD COLLISION AVOIDANCE EMERGENCY BRAKING, AS IT SEEMS TO ACTIVATE FOR NO REASON AT ALL. MULTIPLE TIMES THIS HAS HAPPENED TO MY WIFE, THE PRIMARY DRIVER. SHE'S TOO ANXIOUS TO DRIVE IT ON DAYS WITH INCLEMENT WEATHER WHEN IT'S THE WORST. WE HAVE THE CAR BEING EVALUATED BY THE DEALER, IF THEY CAN'T REPAIR OR DISABLE, SENSORS AND AUTO BRAKING THEN I'M GOING TO GET THEM TO BUY IT BACK FROM ME.

I HAVE A 2020 NISSAN MURANO THAT HAD 3 OCCURRENCES IN A 48 HOUR PERIOD WHERE THE AUTOMATIC EMERGENCY BRAKING SYSTEM CAUSED MY CAR TO STOP IMMEDIATELY WITH NO WARNING OR OBSTRUCTION IN THE ROAD. THE 1ST INCIDENT OCCURRED WHEN I WAS TRAVELING APPROXIMATELY 30 MILES PER HOUR ON A CITY STREET. MY CAR WENT FROM 30 TO 0 WITH NO WARNING. THE MOTOR DIDN'T STALL OUT, THE CAR WAS STILL IDLING BUT THE CAR JUST STOPPED ON THE ROAD. I WAS NOT BRAKING AT THE TIME. I'M THANKFUL NO VEHICLE WAS TRAVELING BEHIND ME AT THE TIME. THE NEXT 2 OCCURRENCES HAPPENED WHILE BACKING OUT OF MY DRIVE WAY. AGAIN THERE WAS NOTHING IN THE WAY TO OBSTRUCT THE VEHICLE FROM BACKING OUT. NO MAINTENANCE LIGHTS OR WARNING LIGHTS SHOWED UP. WHEN I TOOK MY VEHICLE TO THE DEALERSHIP, THEY FOUND NOTHING WRONG. THE COMPUTER DIDN'T SHOW ANYTHING WAS IN NEED OF REPAIR. I TOLD THEM THERE WAS NO MAINTENANCE OR WARNING LIGHT THAT SHOWED ON ANY OF THE 3 OCCURRENCES.
