This warning light has been present since I test drove this car in March 2023. The dealership stated if I purchased the vehicle they would fix the issue before I took delivery after purchasing the vehicle in March 2023 the warring light came on several times within hours of picking up the vehicle. I took the vehicle back to the dealer at least twice within a week or so to have them fix the issue, finally the service department at McGee took the car to Mastria Nissan. Mastria is a certified Nissan dealer. Mastria fixed the issue by re-calibrating the sensor in the front bumper that governs the Automatic Braking System (AEB). This sensor also controls the cruise control system as well. Mastria Nissan fixed the sensor on or around May 12, 2023. It is now September 2023 and this same sensor, same warning light and same error code is coming on continuously every time I drive the vehicle. That is less than 4 months of driving. I have checked around the sensor. There are no obstructions around the sensor. There is no dirt or corrosion around the sensor and it is extremely affixed to its mounting bracket. There is no logical reason for this sensor to be failing within less than 4 months of driving. This is a poor and shoddy design malfunction on Nissan’s part. This defective equipment installed on my 2019 Nissan Sentra is a serious safety concern. If this sensor stops working or malfunctions while driving, this could cause a loss of control while on the road. As this sensor governs the AED system this could cause a loss of control while on the road or worse. I could end up driving off the road uncontrolled. It could also result in a collision with another vehicle on the road. This safety issue needs to be fixed by Nissan.

To be brief, I had a nissan sentra 2019 leased car from 10/19 to present. About 1 year during its lease (3 year), I noticed that the instrument clock freezes and the other clock on the radio panel/screen does not. I have contacted NIssan company and the dealership that I leased the auto from. NO help at all. I have 6 different videos of this situation on my cell phone. The main reason I am contacting this federal agency is that the last time it happened (01/23), I the control instruments on the steering wheel did not function at all. I will admit I never tried to use the various controls when the clock froze in the past 2 years until by chance I did this past month. This may also involve even the car horn (all in the same area). Thus, all I have been asking is to have AV control ( or whatever else) replaced. HOWEVER, it is a safety problem if it also affects, controls on steering wheel area (cruise control, instrument panel , radio , horn etc.) Once car is turned off the system reboots and even thing works, it does not matter about the temperature, speed, time duration of travel, day or night. I know there have been problems with this model as stated on google. As one can see when the instrument displays are not working there can and will be problems including safety. NOTE: I have contacted NIssan customer service dept. After many calls, Nissan did send me an extended warranty for the electical. problem is the company does not honor the warranty. So what good is any warranty if it is never honored!

When driving at speeds above 70 mph, the RPM’s start to surge. Going from 2.5 RPMs to 5 RPMs without any acceleration in speed from the driver. I have video of it when the cruise control was being used and the rpms surged and fell back. The fuel efficiency screen also shows a decrease in efficiency when the rpms go up. Have also had a loss of power when trying to pass and tried to increased speed - yet the engine surged/faltered. It happens every time I exceed 70 mph. I picked the date when I have video of this occurring. However, it happens whenever I exceed 70mph.

The cruise control switch releases brake switch which sometimes malfunctions and does not allow the car to start because it does not sense the brake being pushed. There is no manual work around. It has happened sporadically but recently would not start for three days. I had to take the brake switch apart and clean the inside of excess silicone that gets dirt in it and keeps the contact metal from sensing the brake being pushed. This is extremely dangerous and also keeps the brake lights from working.*dt

I purchase 2019 nissan sentra on 11/6/2019 with 15 miles at nissan of muskogee. Since purchase the automatic emergency braking (aeb) system deactivates and shows a warning on the dashboard 'front radar unavailable due to obstruction.' a crash icon also on dashboard at all times. No cruise control. The car is out of balance. The sensor comes on at all time wether or not there are other vehicle near the car. The dealership and service department alleges that I am the only one with this problem and the parts not available. I brought it in to service. The dealership service barely look at the car nor check codes. The balance is worse. This is cause by a faulty defective radar sensor in the front grill. Service is now waiting for parts that nissan can't get anywhere.
