2020 Nissan Sentra: false forward collision warnings

Filed Nov 20, 2025 · Driver assistance · NY

While in reverse, my backup camera does not engage, instead it will display a blue scree or altered fuzzy incomplete image of what's behind me. While parking, parking collision warning will go off displaying a warning and sound with multiple beeps while my automatic emergency braking system will engage my brakes while reversing unexpectedly without obstacles in the way. This causes whiplash, panic, to the driver and sudden stops causing a hazard to other drivers while wearing out my braking system I've had to replace brake pads and roaders due to warping more frequently than normal function. While driving the forward collision warning will display a malfunction warning on my dash and sometimes engages my brakes unexpectedly with no object in front of me. This has led to sudden stops in the middle of the road causing other cars to slam their brakes so they don't rear-end me. I have reported this to a local mechanic while we replaced my shocks, he stated there was wires loose and he secured them causing my backup camera to work for a short time after. It soon went back to being a blue screen or having an altered fuzzy image when reversing. These has been a reoccurring issue but I am in Germany so I have yet to find a dealership willing to inspect the vehicle. I believe the first issues started in March 2024 after I purchased the car from a friend.

On a few occasions, while driving, the forward collision warning came on causing the car to automatically brake when there were no cars in front of or around the car. Brought the car to dealer and was quoted $2057.50. After that, all 4 automatic door locks stopped working. Brought car to dealer again and was quoted $1375.00 to replace the door actuators for a grand total of $3658.78. Nissan consumer affairs was called and they said they would only cover 50% of the repairs. These items are huge safety issues and Nissan should cover the entire bill.

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.

The forward collision warning keeps malfunctioning; it has done it a total of three times so far once when I first cranked up the car and was just sitting in it for about 10 minutes and it popped on as soon as I switched into drive and it wouldn’t allow me to move so I had to restart my car, second time was on the interstate and luckily nothing bad happened and third time it just popped on when I cranked my car and then cut off as I was driving

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. There was nothing I could do to override it and since there was nothing in front of my vehicle, the cars behind me were not expecting a sudden stop. The car behind me was able to stop in time but narrowly avoided a collision with the rear of my vehicle as a result.

I purchased this vehicle new (172 miles) from a dealership that also sells used cars. The vehicle was driven from a dealership about 75 miles away from where I purchased the car. I was told the other miles were from test drives. I think the car salesman switched cars after the test-drive, while I was calling my insurance company (can't prove it). I never returned to that dealership. I took my car to a dealership closer to my home for service several times. The automatic braking system, forward collision warning, the adaptive cruise control all malfunction on a regular basis. The service person told me that Nissan couldn't service these issues without the manufacture of the braking systems approval. The dealership gave me paperwork on my first complaint- no repairs were made. The dealership gave me paperwork on my second visit stating intermittent electrical issues- no repairs were made. I did not receive paperwork on my 3rd visit. My 3year/36,000 miles bumper to bumper warranty (that never got used) has expired. I decided to live with these issues because the car runs well- getting a lawyer seems pointless. I took my car to a different dealership (over 45 miles away) because of the steering. I was told that it would cost me $170 for diagnosis. I agreed to the charge. The service person then had me call Nissan to get a work order number ( I found that very odd) Why didn't the service person call Nissan? A mechanic looked at the car and told me that I need a new power steering rack and that it isn't covered under warranty. I asked about the recall on the tie rod ends. I was told the tie rod ends have no bearing (ha,ha) on the power steering rack. I was told the power steering rack would cost $2,800 to have installed. The mechanic said he wouldn't drive the car because a wheel might come off while driving. I wasn't charge for my visit and didn't receive any paperwork. My car is parked in my garage with 47,xxx miles on it and is unsafe to drive.

Automatic Emergency Braking and Front Collision Avoidance system has caused the vehicle to brake when there is nothing in front of vehicle, or show "System Malfunction" on the dash. Dealer unable to duplicate but said it happens to most Nissan Sentra's. Found it happens more frequently when there is rain or bad weather.
