NHTSA complaint #11208384, filed 2019-05, 32 miles

“I bought this from a Nissan dealer november 2018. A month after purchase a warning appeared on the dash stating unavailable front radar obstruction followed by the deactivated radar symbol that remains on the dash. I called the dealer to see if any recalls we're out for the collision warning sensor. They said no. I know that the Nissan muranos have also had issues with this sensor. It started going off about once a day, now it deactivates nearly six or more times a day and I driving me crazy. …”

“Just before I hit 1000 miles, the front collision sensor started beeping at random times whether the vehicle was stopped or in motion and ultimately, it had to be replaced. Dealership told me they have seen this happen a lot on the 2018 model sentras. Also, the guard in the inside track of the driver door came off twice and I had to fasten it back on. I did buy it off the sales floor so a lot more people were in and out of it but I still do not feel like that should happen on a brand new car. …”

“Every night I drive home from my night job the warning light and message come on that there's an obstruction on my front sensor. The CVT is trash, my RPM keeps going up and down when I drive on slight incline and I loose speed. Once, on the freeway I lost over 25 MPH where the fastest I could go was 40mph. It was scary and I had my baby in the car with me. The dealer forced me to get this car and said I wouldn't have any issues. Lies and shame on winter chevrolet of pittsburg california!!! They now don't return messages!!!”
