The forward collision warning sensor,the rear collision sensor and the traction lights turns on and off from time to time . The transmission seems like its been force to accelerate
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.
Car continually goes into malfunction mode. It goes away when the car is turned off and re started. It throws a code for mass air flow sensor. Have replaced mass air flow sensor three times. No dealership or mechanic can find an issue. Sometimes, the collision warning goes off for no reason causing panic. This has been going on for a year. Began March 2022.
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.
