Warnings problems of the 2019 Nissan Altima

Every time I put the breaks on or go over any kind of speed bump, it bounces and sounds like warn out bed springs. Out of nowhere the volume on my radio will turn up extremely loud. Its happened more than a handful of times while driving and it scared me to the point of having to pull over to gather myself. Some days it doesn’t work at all. The past 3 months, my front passenger window gets stuck and won’t go up without me turning the car off then back on and still at times won’t work. I’ve had no choice but to leave the window down more than enough times and putting plastic over it until it decides to work again. The engine shakes and it feels like the transmission is about to give.

The airbag system failed to deploy during a collision. The vehicle is currently in not my possession. The airbag control module, sensors, and airbags themselves can be inspected to determine the cause of non-deployment. 2. How was your safety or the safety of others put at risk? my safety was put at significant risk because the airbags did not deploy during the impact. This increased the potential for serious injury to the driver and passengers during the crash, as the airbags are a critical part of the vehicle’s safety system designed to prevent head and chest injuries. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? not yet. The vehicle has not been inspected by my insurance and considered totaled. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? a police report was filed for the accident, and my insurance company has been notified. The vehicle has been inspected by insurance, but both parties have been informed of the issue and an inspection has been taken place 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? no warning lights or airbag system messages appeared prior to the crash. The airbag light on the dashboard was functioning normally before the accident, and there were no indications of a malfunction with the safety restraint system.

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.

I purchased the 2019 Nissan Altima March 22,2024 for the last week the car will start when it wants , the collision sign on the dash comes on and states it’s blocked , the car will stop or shut off while driving ( on the highway with my two children ) the car stoped & a big truck almost ran in the back of me , the seat belt on the right side doesn’t work . Theirs 4 other problems with the car the could get me and my children killed I have documents from autozone about my engine that’s not good . ( and the computer I put on to check the car says stop and repair car immediately) . I have pictures of that also .

Car constantly is breaking saying there are cars in front of me when there are not, especially going under bridges. The light flashes 90% of the time warning me. I have cleaned off the sensor and it still does it and brakes me when I should not be braking.

Ecm is causing my car to stay in a constant malfunction state. The problem began in April 2023 and at first was intermittent. Now it stays in limp mode. The collision and traction control indicators stay on, as well as the check engine light. Two sensor codes came up and those were changed, but now the malfunction will not allow the codes to be cleared. This puts myself, passengers, and everyone else on the road in danger because when it malfunctions, it brakes without warning. Not to mention the amount of gas the car is using. The vehicle was inspected by a mechanic who stated it was the ecm causing it. This needs to be recalled.

Every time I get in my car a start to drive either forward of backing up my car dings and a message pops up ont the display that says "warning ?? malfunction" and shows the car crash button. I have not been in any accidents and it randomly started happening a few days ago. Now I worry that my car may not sensor any objects in my path or that it could trigger my automatic break to kick in creating an accident. I have also researched online and found others who have experienced the same thing but there is no open recall on my vehicle.

The front radar distance sensor becomes blocked and unavailable while driving. This happens every time I drive the car. Several times the warning message came on and the car tried to briefly brake. I took my car into the Nissan dealership and they confirmed the sensor has failed and recommends replacement. This is a known issue with several models of Nissan cars per NHTSA ntb19-033a. This has been happening in my car for about two weeks. I took it in to the dealership as soon as I could after noticing the problem. I believe my car was built at the end of 2018 and has this faulty sensor reference in NHTSA ntb19-033a or clearly they have not rectified the problem fully. I think 2019 vehicles should be added to the recall.

Care is giving error of "engine malfunction reduced speed, service soon" with engine, traction and collision lights activating at the same time. Car than slows down and has shut off. This error happens while driving or just by having it on. Also while stereo, buletooth or carplay is on the volume will decrease on its own unable to turn up volume with knob. This has been happening since I bought the care in 2021.

I was driving on a slightly damp road in the evening (dark). A warning flashed on my dashboard saying that their was obstruction in the road. Suddenly my braking assistance activated causing my car to come to a complete stop. I checked my surroundings, nothing was in the road, beside me, or behind me. Nissan has not claim responsibility for this sensor error. Instead told me that there were damages to my bumper, which was hard to believe. I was recommended to contact my insurance company. An appraiser found no damages to my car or bumper. Case has been dismissed by insurance company.

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.
