I was leaving for work, backing out of the driveway, and the brakes just locked up out of no where. I’ve done this multiple times and the brakes have never done this. I tried pulling up and trying again, turning the car off and back on, and backing a different way out of the driveway. It kept locking up on me and nothing was in the way. My husband had to eventually take me to work. The automatic braking system failed. I’m not sure if it is available for inspection upon request. At the time, my safety or anyone else’s safety was not at risk. I just worry about if it happens while I’m driving on the road. That could defiantly not only put me at risk but also other drivers. No the problem has not been reproduced or confirmed by a dealer. It just happened this morning. The vehicle has not been inspected. No warning lamps. It did pop up the car with the 3 blocks in front of it on the screen like I’ve seen before, prior to failure, but not the warning about the automatic braking system.

I'VE HAD THE VEHICLE FOR 5 YEARS AND IT CONTINUES TO OCCUR, NEARLY CAUSING A TRAFFIC COLLISION. TWICE THIS YEAR, THE VEHICLE MADE A COMPLETE STOP ON THE HWY AND TOOK A MINUTE BEFORE I COULD RESUME DRIVING.

This car is going to kill me! It randomly hits the brakes on the highways! I am literally driving a deadly weapon. I turn the emergency brakes off and had it checked and STILL brakes. It break everytime I pass a shade spot on the road and even highway going over 60 miles per hour! It hits the breaks while I am in traffic making the driver behind me almost hit my car. It breaks whenever I go under a tree. It breaks when I am in a parking garage when there are NO cars around. It breaks randomly in traffic with no cars too close by to create a collision. It breaks in front of a school bus that was driving close behind me. It hit the breaks going 30 miles per hour. If the school bus would have hit me then that would be child endangerment. The bus driver thought I would break checking him but it was hard to explain it was my emergency breaks. It’s been getting so bad that I am writing a complaint until something can be fixed or changed. It’s ruined my breaks in general from always setting off the emergency breaks. It is not even emergency breaking, it’s breaking to kill at given moment. It’s ruining my car and my ability to drive! This is not correct and it’s keeps going off even more. I am scared to even drive it. This has been happening since I got the car but for the past year since I turned off the sensor, it’s gotten SO much worse. It can turn deadly on my end or someone else’s. This was not properly designed for safety. It’s doing the exact opposite. This happens literally every week! So there is not way of giving you every single date nor do I have the time to wipe my phone out to take a video during those moments because it’s random.

Regardless if I'm on the highway or back road no transition from one lane to another needs to be initiated , my whole dash will light up red and the car will come to a complete stop , at this time I just hold on and brace myself .Im a RN w/2 kids I went back to the dealer they said they checked it out but on my own I found out the car was in 2 accidents those things were not revealed to me during the buying process. I didn't know how to report this Im pretty ignorant to this type of thing however I did complain to gm by way of phone few times I called early on. No one at the dealership will help. Im literally in fear of me and my children's life. I test my luck because I don't know what else to do and can't afford another vehicle. Please help this complete dead stop sometimes turns the back end of my vehicle if im going over 70 when it stops, for this reason I drive like 40mph. I hope knowing this issue you can help there is no reason I know of for this incident which is now happening approximately once a week. Again this happen almost immediately after buying ,I went to the Mngr no one will help but this is very scary for me and two children will it take a nurse dying in an accident before someone does something , I dont now what else to do Again out of nowhere no matter the speed the dash turns red all lights come on and vehicle comes to ABRUPT STOP.Thank you and its at this point once a week,by the way I only guessed the parts involved d/t effects of incident I do notknow which or what from the car would have these issues from because I absolutely bought it like this

I noticed a month ago I was driving and both the rear and front emergency braking lights came on in my dashboard but the car never actually began to brake. Fast forward to today when I was backing in to park my car and the emergency brake engaged and I could not back in. Nothing was around me, I wipe off the sensor and it still would not let me back in. I had to turn off the emergency brake system just to back up my car.

This has been happening multiple times since December 25th, 2023. Presently, it's in the shop for the 6th time. This orange light comes on and then right after the vehicle just stops or slows down. Nothing is in front of or behind me. It's random...happens at night or anytime during the day and it stops itself while driving. It has been taken to the dealership 6 times since December and the problem has not been remedied. It is scary getting into the vehicle every time because I wonder, will it happen today? And what if someone is behind me? That could cause a major accident with injuries.

I've taken my car for repair service 4 times due to a malfunction warning and front driving aids off warning. They replaced speed sensor as well as cv axle as well as a hub and bearing and it still is not driving right and has almost caused me accidents with my children in the car to where I pulled over and cried I was scared to continue driving. They cannot figure out the problem.

The forward collision warning light comes on saying their is a malfunction. It stays on for a couple of days, and then it goes away and comes back again a couple of days later. I had my sister husband hook up a diagnostic scanner on the car, and he said that it displayed no error codes for the problem. I believe this should be a safety recall because i noticed a lot of people driving the 2020 nissan altima have the same problem as me.

I have been noticing electrical issues with the vehicle that have been going unresolved. This is the third time I'm taking it to a dealership. On 15 Nov 2022 the vehicle gave a frontal collision warning with no other vehicles around it felt like the emergency braking system engaged because the brakes became solid as a rock. I had to put the car into park and restart the vehicle to begin driving again. Then on 16 Nov 2022 the car battery was dead around 4:48 pm and I had to get the taco shop's help, they gave me jumper cables and my wife's co-worker got the car started. Now, 18 Nov 2022 the vehicle is in another dealership waiting to see what they say and the car is staying the weekend to be evaluated.

It has come on 12 times in the past 15 days.
