2020 Nissan Sentra Vehicle speed control Problems

“The front radar (obstruction detector) is not working properly. The car will randomly break even when there is no obstruction in front of the car. This happened 3 times in february 2021. Each time I took the car to the dealership. They initially brushed me off and blamed snow, rain and soot. I called nisan corporate office and the told the dealership to take a look at the car. The dealership stated that the detector was changed. However, three weeks later it happened again twice within a two-week period. A sudden break, the detector warning flashing and no obstruction. …”

“I was traveling on a multi lane road at a speed of approximately 45 mph. There were cars directly behind me. Multiple pedestrian crossings were in front of me but the pedestrians had already crossed the road and were safely on the sidewalk. However, the caution lights from the crosswalk were still illuminated from the pedestrians that had previously crossed. As I reached the pedestrian crossing, the vehicle’s front collision warning system activated and immediately applied heavy brake pressure. …”

“The contact owns a 2020 Ford Nissan Sentra. The contact stated while driving at undisclosed speeds and depressing the accelerator pedal, the vehicle hesitated. No warning light was illuminated. A dealer was contacted. The vehicle was not taken to the dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 80,000.”

“When driving the forward collision avoidance system acts up. It will randomly slam on the breaks when nothing is in front. It also happens when cruise control is on, it will slam the breaks with an empty road ahead. It also thinks that there is something ahead when the road is clear ahead. This needs to be looked at because the number of complaints in regard to this is silly.”
