Equipped with ProPILOT Assist and Intelligent Cruise Control inclusive of Lane Keep assist, traffic sign recognition, and Direct Adaptive Steering. Vehicle has just under 60,000 miles and still under warranty When in ProPILOT Assist/Intelligent Cruise Control, when hands leave the steering wheel, car failed to give a dash visual warning, sensory warning, or did not take control of the vehicle to bring it to a safe stop. This of course is a serious safety issue if the driver becomes incapacitated to the point of not being able to respond to the warnings. The car could obviously go through intersections without stopping or possibly get off course resulting in collision with other vehicles, structures or people. This first appeared on interstate highway travel on a trip to Florida in late November and bought in to Smith Infiniti of Hunstville, AL on [XXX] As of this date, [XXX], it has been in service department for nine (9) weeks with no correction of the failure.

Jan 25,2021 Highway 35 San Antonio Texas Display board lights turned off for a few seconds it made a click sound and the car turned off and turned back on for a few seconds, stalling the car. The automatic break was activated and deactivated at the same time. Trying to stop the car. This is the third time since octubre 2021 that this happens. My safety and the safety of the other drives was at risk, I can’t drive this car anymore because it may cause an accident. Approximate a month ago the car stoped in the middle of Stone Oak street in San Antonio Texas. I put the car in reverse and the car started working again. I took the car to the agency I was without a car for Several days because the agency doesn’t have a car available for rent. They could not find the problem of the computer glitch. Please the maintenance records for more details.

Incident

While driving vehicle, randomly vehicle brakes are applied on their own, causing vehicle to suddenly slow down in traffic. Red warning light appears on the dash. This has occurred 6-7 times over the past 2 years. 3 of the times occurred on the interstate, causing vehicle to drop speed from 60-40 within few seconds. The other 3-4 times have occurred while driving underneath a light rail walk way and an underpass. Most recent incident was 12/25/21 on interstate. I am concerned this will contribute to a car crashing into the rear of my car. I had vehicle checked by my dealer today 1/7/22, and they were unable to duplicate the issue. They have submitted a report to Infiniti. I was unable to upload the documentation from Mike Ward Infiniti

-DISPLAY SCREEN COMPLETELY BLACK, BUTTONS WOULD WORK, RADIO WOULD WORK, HEATED SEATS WOULD WORK, AC WOULD WORK BUT ABSOLUTELY NOTHING ON THE SCREEN. I DID NOT BRING THE VEHICLE IN BECAUSE I THOUGHT 'THAT WAS WEIRD' AND IT WOULD JUST GO AWAY. UPON STARTING THE CAR THE NEXT TIME, EVERYTHING WAS NORMAL. -SEVERE CONDENSATION INSIDE VEHICLE WINDOWS. CONDENSATION WAS SO SEVERE THAT WATER WAS ACTUALLY DRIPPING FROM MY WINDSHIELD ONTO THE DASHBOARD AND DRIPPING FROM THE SUNROOF ONTO MY SEAT. -DISPLAY SCREEN BLANK AGAIN EXACTLY THE SAME AS FEB INCIDENT, THIS TIME I DID BRING THE VEHICLE IN AND THE ENTIRE DISPLAY SCREENS WERE REPLACED. -A/C DID NOT WORK. WAS DRIVING GF TO AIRPORT AND SHE WAS GETTING HOT DUE TO RUSHING, THE A/C ONLY BLEW LIKE A FAN, IT DID NOT BLOW COLD AIR AT ALL. I TRIED ALL THE VARIATIONS OF BUTTONS TO TRY AND GET IT TO WORK. I EVEN TURNED OF THE CAR ON 3 DIFFERENT OCCASION AT STOPLIGHTS TO SEE IF THE VEHICLE WOULD 'RESET' ITSELF. IT DID NOT. WE DROVE ALL THE WAY TO THE AIRPORT (APPROX. 30 MILES) WITH NO AC. -CD PLAYER DID NOT WORK. THE CD FUNCTION DID NOT WORK, WOULD NOT EJECT CD OR ACCEPT CD. WAS TOLD THAT A 'RECONFIGURATION' FOR THE SOFTWARE MULTI-AV UNIT NEEDED TO BE PERFORMED. -FM PRESET STATIONS NOT WORKING PROPERLY. PRESET STATIONS GO FROM 1-6 AND THEN 7-12. MY STATIONS ONLY WENT TO CHANNEL 6 THEN WENT BACK TO 1. I COULD NEVER GET THE STATIONS TO GO TO 7-12. THEY WORKED BEFORE I BROUGHT THE VEHICLE IN FOR THE CD PLAYER PROBLEM. THE CD PLAYER FUNCTION WAS FIXED BUT THEN THAT CAUSED THE FM PRESET FUNCTION NOT TO WORK PROPERLY. I WAS TOLD THAT THERE IS A SOFTWARE 'GLITCH' WITH THE HD STATIONS. I WAS TOLD THAT I CANNOT USE THE HD FUNCTION. -REAR SONAR SENSOR LIGHT DEFECTIVE. I CAME OUT TO START MY CAR AND THIS LIGHT WAS ON. WAS TOLD TO SEE IF THE SENSOR WAS 'SUNK IN.' WAS ADVISED IT MIGHT BE ELECTRICAL FAILED SENSOR.
