general problems of the 2019 Nissan Altima

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.

Driving down the road and my parking brake light came on when it wasn’t in park and I was on a highway. Malfunction light came on, but car runs fine and had it looked at with no problems.

Emergency brake engaged when there were no objects near the vehicle. Vehicle stopped.

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.

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.

While driving straight on a two lane road, steering wheel suddenly locked, unable to regain control the car was locked in a turning position causing the vehicle to crash into a pole. Car is totaled. No rain, low speed and wasn’t turning when it happened.

Automatic brake system malfunction.

The contact owns a 2019 Nissan Altima. The contact stated while driving at an undisclosed speed, the vehicle started shaking and vibrating. Additionally, there was an odor of burning rubber. During the failure, the vehicle would not immediately stop while depressing the brake pedal. The vehicle was taken to an independent mechanic to be diagnosed. The contact was informed that the passenger’s side rear brake caliper was faulty and that the entire rear braking system needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure. The VIN was not available. The failure mileage was 46,593.

Driving at maybe 10 -15 mph in an empty parking lot about to park and car aggressively brakes for no reason. Completely startled and unsettled me its a good thing no one was behind me.

I have had two separate incidents 8 months apart. While driving in the city limits on both occurrences going about 45 mph both times, without any notice or potential collision the aeb engaged, and a red flash came across my dashboard. The first time it was just me in the car with very little traffic around me, whereas with the most recent occurrence the traffic was heavier. I had my mother and 2 young children in the backseat, with a truck that looked like a f-150 not far behind me. I have been to the dealership that I bought the car from, and I have twice gotten the results that they are unable to duplicate the problem, so I guess it can't be rectified. Thankfully I have not had an accident, but driving the car in that condition raises the risk of a collision, and I'm done with that risk.

While driving straight over the upper roadway gw bridge, my automatic brakes engaged with no objects in front of my car. This caused my front brakes to lock which caused me to drift left into the left lane, at which point I was almost crushed by a speeding 18-wheel truck.

Tl-the contact owns a 2019 Nissan Altima. The contact stated that when driving at 20mph, the contact engaged the brake pedal attempting to bring the vehicle to a stop. The vehicle failed to stop and crashed into a mail delivery truck. The contact stated that mail delivery truck did not received any damage.

The contact drove the vehicle to an unknown auto repair garage. The contact suffered injuries to the left shoulder, the contact did not received medical attention. The vehicle was not repaired. The contact also advised that the vehicle should come to a complete stop on its own when coming too close a vehicle. The manufacturer was not contacted. A police report was filed. The approximate failure mileage was 2,300. Li.

When I try to start my car, the steering wheel and break pedal are locked. When I press the brake and push the start button nothing happens. The battery is charged and there is no corrosion on the cables.

The vehicles automatic emergency braking (aeb) system does not operate properly. This vehicle has already had a radar replaced. The vehicle continues to brake when it shouldn't.

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 slow the vehicles speed. The failure occurred although no objects were present nearby. The cause of the failures were not determined. In addition while driving approximatly 35 mph and pressing the brake pedal the vehicle slowed before the braking system malfunctioned causing the vehicle not stop and crash into the rear of a truck. No injuiries 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. Jft.

Automatic emergency braking system has serious issues that Nissan knows about but can't fix. Warning lights on dash come on at random times, both solidly out and flashing, and even worse, at times with no other cars on the highway, the vehicle decides to slam on the brakes. Very dangerous. All the dealer can say is we checked the car and no codes were found, yet there are multiple complaints about this and two class action lawsuits. Same thing happens at random times when backing out of my driveway. Different system in the car but same result - car brakes for no reason - nothing behind me, no obstructions. Not quite as serious as the front emergency brakes not working but still an issue. This has happened multiple times but I entered today's date as today was the latest occurrence. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.

Tl the contact owns a 2019 Nissan Altima. While driving 20 mph and depressing the brake pedal to make a right turn, the vehicle failed to stop and shook violently. In addition, the instrument panel illuminated, indicating a malfunction. As a result, the contact rear ended another vehicle. The air bag did not deploy. There were no injuries and a police report was filed. The vehicle was driven to a collision center, but was not diagnosed or repaired. The contact called suburban Nissan of farmington hills (37901 grand river Ave, farmington hills, mi 48335, (248) 471-0800) and scheduled a diagnostic appointment. The manufacturer was made aware of the failure and provided case number: 38133183. The failure mileage was 2,790.

I've had my vehicle for 1 month and on at least 10 different occasions my aeb system has locked my brakes up on me for no reason. Each time I've been driving straight and it's been in my work parking garage when no other vehicles or people are in motion around me. Although I've been lucky so far and it hasn't caused me to be rear ended I still see the potential for that happening if this continues and is not fixed.

Tl the contact rented a 2019 Nissan Altima. While driving 50 mph, the abs activated on its own and the contact slammed on the brake pedal. The failure occurred several times. The dealer and manufacturer were not contacted. The contact did not know if the vehicle were diagnosed or repaired. The failure mileage was 2,500. The VIN was invalid.

Adaptive cruise control and automatic braking are disabled due to "front radar blocked". This is a brand new vehicle I have had for about two weeks (less than 1,000 miles). After doing some internet research, this appears to be a known issue with Nissan vehicles since 2018. I believe my vehicle was manufactured in late 2018. The issue was first noticed while driving with the cruise control engaged and I kept getting closer to the vehicle ahead of me without my vehicle automatically slowing down (I. E. , the car maintained the cruise control set speed. ) after manually braking and resetting the cruise control, the cruise control would eventually shut off and the attached message would be displayed. Prior to the issue being observed (approx. First 500 miles driven), the adaptive cruise control and automatic braking worked fine.

I own a 2019 Nissan Altima awd and have experienced a few problems. The most significant problem is the defective forward collision safety feature. Two times the vehicle has improperly and abruptly applied brakes, the feature is intended to avoid collision, but instead its malfunction is creating road hazards. I contacted Nissan consumer affairs and they have evaded me and everytime I call they say you have been assigned a case and someone will call you soon. I attempted to service the vehicle two times this week at two different Nissan dealerships. One turned me away stating it's a known problem and Nissan does not have a fix yet. The second Nissan dealership was in the process of issuing me an alternate vehicle when they received a call from the same folks who won't return my call Nissan consumer affairs instructing the dealer not perform any service or a loaner. This is so outrageous, but I actually have it in writing to prove the level of negligence and ill service to force a customer to stay in a vehicle that they don't feel safe in. None the less their failure to do their due diligence. The safety feature malfunctioned on the highway once and the next time on a incline ramp in mall parking garage to a forceful hard stop. I have spoken with 3 general managers and 3 different consumer affairs call center reps, but yet no service or call back from Nissan north America. Negligent negligence negligent. Nissan is not what it used to be. Stay far away and tell everyone you know to stay far away. I am the owner of a model year vehicle with full warranty and this is how they are treating me. What would you get?.

Back in the July I got into a rear end collision, the emergency braking should have kicked in but it did not. Since then, the emergency braking has applied multiple times in the open by itself with no cars ahead or in view. It makes me very nervous to drive this. It has happened both on city streets and the highway. I tried telling the Nissan dealership and they have no knowledge and are not willing to work with me for failure and damages.

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.

Cars aeb would activate with no obstruction on the city road while the vechicle is in motion. Would brake really hard and release. Need help!.

Automatic emergency braking (aeb) function failed at a red light. Aeb had been set in a 3-vehicle distance. However, upon arriving at the red light, on a city street, with another vehicle in front of us, Nissan Altima 2019 didn't actually respond to the condition and kick off its aeb system to 1) slow down 2) stop the moving vehicle. This is a driving experience dated on June 01 2019.
