I changed the Air Mass Flow sensor and it’s still showing the check engine light on my dash board and giving me the same code after replacing it brand new. My brakes sound horrible after replacing both sets of brakes, front and back. The Foward Collision Warning sensor did not respond in a timely matter, resulting in a minor fender bender.

What owners say
Adaptive Cruise control and Forward Collision warning has failed. The cruise control will not engage. The Electronic braking system has malfunctioned and this has somehow disabled the cruise control on the vehicle. The car will still brake. I understand that this has been known issue with Nissan but they are not willing to repair it.
Please note that I have my car regularly inspected for oil changes and maintenance. The adaptive cruise control stopped working August 2022. The car displays "malfunction" on the dashboard. This was inconvenient and at first intermittent, but I did not think it was putting any persons safety at risk. I went to a local Nissan dealership in NJ and they stated it would cost $600 to replace, but no safety issues. Therefore I did not get this fixed at the time. On March 14 2023, I was merging onto a highway in daylight around 4pm. It had started flurrying, but no changes in visibility. There was no car immediately in front of me. The collision warning suddenly came on and the emergency brakes were activated while attempting to accelerate onto a 65 mph highway in NJ. It was extremely startling. It certainly could have caused an accident, especially when vehicles are accelerating to merge onto a highway. I was fortunate that there was no car immediately behind me. On April 26 and 27 2023, the emergency brake was activated again due to a collision warning while in a parking garage. The only correlation I can think that ties these occurrences is when driving from a shaded to sunny location. All three times it also occurred during acceleration. This new problem is quite concerning and dangerous.
08/24/22 driving on a three lane highway with no cars in front of me in any lanes, no pedestrians, animals or any obstacles going 50 mph, the car just stopped and the forward collision warning activated and the car stopped. Took the car in to the local dealer 09/08/22 where technician noted they could not replicate the issue on test drive. Dealer service pointed the issue to 12/2021 accident and wanted to charge me $2,020 to fix. Car has less than 17K miles and is under warranty.
My fiancé and I were driving late at night on a straight, one lane road going just over 40 mph with NOTHING in front of us. For no reason the pre-collision front sensor went off indicating we had the potential of hitting the vehicle in front of us even though there was nothing there. Moments later the dashboard went white showing a red triangle and the automatic braking system came on engaging all the brakes and abruptly reducing the vehicle's speed to approximately 15mph before it disengaged. That this time we had no control over the speed of the vehicle and could only steer the car to the side of the road. Had another vehicle been behind us there would have been an awful accident where us and the driver behind us would have been injured as there is no way anyone could have anticipated such an inappropriate speed change at that time. I brought the vehicle into the dealership days later. They could not duplicate my concern. They found past trouble codes of C1A16 & C1A17 on the vehicle's history. They recommended calibrating the distance sensor and road tests but were not confident this would fix the problem and stated a new sensor may need to be purchased. Upon experiencing this traumatic event in my Nissan vehicle I posted my experience on Facebook and had 3 people I personally know reach out to me saying they experienced similar events in their Nissan. All the people had 2017 or newer Nissans vehicles that included the Sentra and Rogue models. No warning lamps, messages or other symptoms of the problem appeared prior to the failure besides the pre-collision sensor incorrectly coming on as described above. The vehicle is available for inspection upon request.
Forward Emergency Braking/Collision Warning - Activated without cause or other indication - The vehicle suddenly applied brakes - then released them - two occasions - on 01/21/2022 a New Castle County Police Department vehicle following me swerved into adjacent lane to avoid collision Dealer service was unable to replicate event/s - no other vehicle inspections. No other previous indicators or warnings, Second event occurred on 01/23/2022 at about 30 mph.
The forward collision warning malfunctions and a warning light is displayed. This used to be an intermittent problem which now occurs every time I drive the vehicle. This is an important safety feature in the vehicle.
Forward collision warning system not working . Provably the front grill sensor (bosh) is bad. Car is under warranty. But dealer don't want fix it
Tl* the contact owns a 2019 nissan altima. The contact stated that while driving at various speeds the collision avoidance system would randomly activate and reduce the vehicle's speed. The failure occurred although no objects were present nearby. The cause of the failures were not determined. In addition, while driving approximately 35 MPH and pressing the brake pedal the vehicle slowed before the braking system malfunctioned causing the vehicle not to stop and crashed into the rear of a truck. No injuries were reported and no police was called to the scene. The manufacturer and local dealer were not notified of the failure. The VIN was not available. The failure mileage was 16,000.
The intelligent forward collision warning is broken warning lights come on and say it's not working driving on the freeway, when you turn off the car it resets but driving again it shows the warning lights again. Only 6000 miles
