2019 Nissan Sentra Speed Control & Cruise Problems

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.

At 65mph, I hit a tiny bump. The automatic braking system and collision detection warnings triggered and I lost all acceleration ability. I was nearly hit by a semi while coasting off the freeway in traffic. When inspected by Nissan the first time it happened (9/20/2021), the lights turned off and the computer reset. They did a warranty recall for something unrelated and told me they fixed it. On 5/13/2022 it did it again, and on 5/30 I was told it would not be covered under any warranty - all diagnosis and repair would be my own cost. A sensor should never take control of the car away from the driver. The only way to regain acceleration is to turn the car off. Wait. Turn it on. Wait. Use the menu, turn off Automatic Emergency Braking, drive.

I PULLED INTO A CHICK-FIL-A DRIVE THRU. THIS FAST FOOD CHAIN HAS EMPLOYEES OUTSIDE THAT COME TO YOUR CAR AND TAKE YOUR ORDER. THE GUY THAT CAME TO ME ASKED ME IF SOMETHING WAS WRONG WITH MY CAR. HE SAID IT SOUNDS LIKE THE ENGINE IS RACING. I DIDN'T RECOGNIZE IT UNTIL HE MENTIONED IT. WHILE I WAS SITTING IN THE LINE WAITING TO PICK UP MY FOOD, I NOTICED THE ENGINE WASN'T RACING AS BAD AS IT HAD BEEN. WHILE I WAS SITTING IN THE DRIVE THRU LINE, THE CAR ACCELERATED AND TOOK OFF. I LOST CONTROL OF THE CAR. I HIT ANOTHER CAR AS THE CAR LEFT THE PARKING LOT AND RAN INTO THEIR FENCE. THE FENCE WAS THERE FOR SAFETY MEASURES, TO KEEP YOU FROM GOING DOWN AN EMBANKMENT. THERE ISN'T A POLICE REPORT. THE POLICE DIDN'T COME BECAUSE IT WAS PRIVATE PROPERTY I CAN PROVIDE INFORMATION, (IF REQUESTED) FROM MY INSURANCE COMPANY. THEY DECLARED THE CAR TOTALED ON 4/9/2021.

FRONT RADAR COLLISION WARNING ACTIVE, IT DOES NOT SLOW OR STOP THE CAR IN EVENT OF OBSTRUCTION.IT GOES OFF EVERY TIME I START THE CAR AND WITHIN 5 MINUTES OF DRIVING IT FAILS AND DEACTIVATES THE AUTO STOP FUNCTION.

FAULTY RADAR ON FRONT OF MY CAR CAUSED SPEED CONTROL AND EMERGENCY BRAKING SYSTEM TO MALFUNCTION WHILE IN MOTION. THIS OCCURRED SPORADICALLY SINCE NEW AND THEN CONSTANTLY FOR LAST 3 MONTHS. I FINALLY TOOK THE CAR IN FOR TROUBLESHOOTING LAST WEEK AND THE RADAR UNIT ON THE FRONT OF THE CAR WAS REPLACED. THIS FIXED THE PROBLEM BUT IT SHOULD BE BROUGHT TO SOMEONES ATTENTION BECAUSE OF THE SAFETY HAZARDS INVOLVED.
