As I was driving across the railroad tracks, my car just stop. There was no warning or indication that there was a problem, it just stopped and all the lights shut down as well. No brake, head or emergency lights worked.

On January 29th 2022, we drove the car on the interstate at about 65-70 mph for over two hours when suddenly, the vehicle completely shut off. We were able to navigate safely into the shoulder while the power steering, dashboard, and engine were all completely off. No lights or other errors appeared. We took the car to an auto zone where they checked and cleaned the battery from corrosion. Assuming we were fine, we embarked on the three hour journey home on the same highway the next day. We drove the car for about 45 minutes short distances with no errors. As we got ready to return home, we got on the highway again. About 30 minutes into the drive going the same speed, the car shut down again. No warnings or errors like the last time. We took the car to a Nissan dealership in Monroeville, PA. They held the car for a week doing inspections and say that there are no errors. I'm wary of the safety of the vehicle and nervous to drive a car that unexpectedly shuts down on the highway

Rpm’s spike up to high levels just to get up to 45/50. I have to let off gas & almost stall out to press gas to try & catch it into higher gear. This happens most the time, but not all. 45/50 but won’t go past 55/60mph, let alone 70-80 on I90/I94. & if it’s really bad then I have to be almost gas to the floor just to maintain any speed once up to 40/45++. Especially higher speeds. & other times O/D kicks in at random times random speeds & then I have to park or EMERGENCY park because reduction of speed won’t stay up, or will not even get to 55/60… I bought this car New March 2017. Maybe 10-20 miles. We had extended warranty. I told them multiple times about the recall & the studdering since a year of owning in 2018. They said they didn’t find anything or that they did the repair. Then during covid we didn’t have funds to have maintenance but about 6 months ago I told them to fix everything do all recalls, do the issues we thought & they agreed & then never did it. Now we aren’t in warranty. We put in 2g of repairs up keep, thought it was low price. But then said ok add in auto start & do the other fluffy stuff. Well… have 9-10 grand left & they wanted to buy it & get us into another 450 car loan. We refused. & repeatedly asked why the recalls & repairs seem to have never been done. & Nissan in crystal lake IL where we have been doing business with for years now claim that the only recall is for the break lights…. & that it’s my fault for doing 60 thousand miles before coming in… during covid… when this has been an issue. Nissan dealership bought, Nissan loan, Nissan warranty. & a solid 6 years at least just to be in a money pit because “no one knows what’s wrong”, it’s the not repairing while I was in warranty telling them the same things. Now I’m not in warranty and they want me to come in to buy a new Nissan from them again, & roll in the remaining balance ️ I don’t feel safe with Nissan, let alone hulling my 2 children at/under 4… plus I use that car to work

Getting a sulfur (egg smell) through vents when air conditioner is on. Not sure if something a fautly with fuel system? Car is only 4 years old with 40+ thousand miles on it.
Electrical system, Service brakes, Engine, Sep 5, 2021
About 6 months ago I had the brake light switch repaired because my car wouldn’t start due to the brake lights not coming on. So yesterday I’m almost was rear ended due to m break lights not coming on, and then got stranded at midnight , by myself, out of town. Finally I put both of my feet on the break and pushed as hard as I could and it started. Called Nissan in Tracy, CA they stated there’s no fix and to have it towed there if it won’t start. Well what if someone slams into me? They also did not offer to change the switch like the safety recall states they should. This dealership has now put my safety and my children’s safety at risk.

I WAS DRIVING ON SEVERAL OCCASIONS AND THE CAR WOULD JUST SLOW DOWN OUT OF NOWHERE ON THE HIGHWAY. I COULDN'T GET THE CAR PAST 80 OR IT WOULD SHAKE. IF I STOPPED THE CAR OR EVEN SLOWED DOWN, (ANYWHERE, STREET OR HIGHWAY) THE CAR WOULDN'T MOVE AT ALL. I WOULD BE PUSHING THE PEDAL ON THE FLOOR FOR 10 MINUTES JUST TO GET IT TO 5MPH. IF I WOULD GO UP A SMALL INCLINE, THE CAR WOULD ROLL BACK AND BARELY STOP ( ALMOST RESULTING IN SEVERAL POTENTIALLY FATAL COLLISIONS). AT TIMES MY REVERSE WOULDN'T EVEN WORK IF I COULDN'T PRESS THE GAS AND IF IT DID WORK THEN I COULDN'T DRIVE FROWARD. IT WOULD TAKE ME ALMOST 30 MINUTES TO GET HOME FROM WORK AND MY JOB IS EXACTLY 10 MINUTES IN A STRAIGHT LINE FROM MY HOUSE (ON THE STREET. NO HIGHWAY). IF THAT GIVES ANY PERSPECTIVE. ONCE THE CAR WAS PARKED IT WAS FINE. ALL THE PROBLEMS OCCURRED WHILE THE CAR WAS IN MOTION.

I WAS DRIVING ON THE HIGHWAY AND NOTICED THAT AS I ACCELERATED, MY RPM WOULD INCREASE BUT MY SPEED-O-METER WOULDN'T. AND IF IT DID MOVE, IT MOVED VERY SLOWLY.
Power train, Vehicle speed control, Engine, Feb 7, 2021
THE CAR WAS IN MOTION WHEN I LOSS 90% ACCELERATION AND VELOCITY WHILE DRIVING. VERY, VERY SCARY! I WAS ON THE HIGHWAY WHEN THIS OCCURRED. I PROCEEDED TO CHECK THE BATTERY, ALTERNATOR, AND STARTER BY AAA WHEN A SERVICE CALL WAS PLACED TO INSPECT THE VEHICLE AT MY HOME. AAA'S. THEY INFORMED ME THAT THE BATTERY, ALTERNATOR AND STARTER ARE GREAT AND THAT THESE THINGS WERE NOT THE REASON WHY THE CHECK ENGINE LIGHT CAME ON AND HAS REMAINED ON. THE CAR IS ONLY 3YRS 11MNTHS OLD. I GET THE STANDARD OIL CHANGE BUT NISSAN HAS DISCONTINUED TO USE CONVENTIONAL OIL. WHICH IS THE RECOMMENDED OIL FOR MY CAR. I ALSO GET THE CAR SERVICED AS NEEDED. IT IS EXTREMELY DANGEROUS TO DRIVE MY CAR. I CANNOT DRIVE IT PERIOD. IT SUDDENLY LOSES POWER 60 TO 120 SECONDS WHEN THE CAR IS IN MOTION.

MY CAR HAVE BEEN GIVING ME PROBLEMS SUCH AS CUTTING OFF IN THE MIDDLE OF DRIVING AND I DON'T SEEM TO BE GOING OVER 45 WHEN THIS HAPPEN I TOOK IT TO NISSAN TO GET IT FIXED AND STILL DOES THE SAME THING WITHOUT WARNING THE CAR LOCKS THE STEERING WHEEL AND BRAKES THE LIGHTS ON THE DASH LIGHT UP AND THE CAR CUTS OFF.
Engine, Oct 20, 2020
ON MULTIPLE OCCASIONS UPON ENTERING THE CAR, PRESSING ON THE BRAKES, AND PUSHING THE START BUTTON, THE CAR WILL NOT START. I HAVE TO WAIT SEVERAL MINUTES, SOMETIMES AS LONG AS AN HOUR AND EVENTUALLY THE CAR STARTS. IT STARTS AFTER MULTIPLE ATTEMPTS. THIS HAS HAPPENED LATE AT NIGHT, SINCE I TRAVEL AND WORK MULTIPLE DIFFERENT SHIFTS AS A TRAVEL NURSE. IT'S EXTREMELY SCARY TO LEAVE WORK IN THE MIDDLE OF THE NIGHT, GET TO THE DARK PARKING LOT, AND YOUR CAR NOT START.

PURCHASED MY CAR IN AUG. OF 2017. JAN. 2018 WAS THE FIRST OF 7 TIMES I HAVE TAKEN MY CAR IN FOR THE CHECK ENGINE LIGHT. CASE IS AT NISSAN NORTH AMERICA IN ARBITRATION WHERE THEY WANT TO 'COMPENSATE' ME $1500 TO ESSENTIALLY SHUT MY MOUTH. THERE IS A SIGNIFICANT LAG IN THE ACCELERATION NOT ONLY FROM A STANDSTILL , BUT ALSO WHILE IN MOTION TRYING TO ACCELERATE TO HIGHER SPEEDS. THE CAR WILL NOT GO FASTER THAN 55 MPH UP A HILL. WHEN THE CAR IS ON SLIGHT INCLINES THE VEHICLE LOSES POWER IN ATTEMPTING TO CLIMB AND THE ENGINE TACHOMETER READINGS CLIMBS WELL ABOVE THE DESIGNED RPM SPECIFICATIONS. THIS HAPPENS ON LEVEL GROUND. WHEN ACCELERATED FROM 45 MPH TO 55 MPH THE TACHOMETER WOULD APPROACH 6000 RPMS PRIOR TO SWITCHING GEAR. IT DOESN'T OCCUR 100% OF THE TIME, THE VEHICLE CONSISTENTLY REACHES CLOSE TO 6000 RPMS PRIOR TO SHIFTING TO A HIGHER GEAR. AS I DRIVE I ALSO START TO NOTICE A BURNING SMELL. MY CAR IS CONSUMING EXCESSIVE FUEL COMPARED TO ANOTHER 'LOANER' 2019 NISSAN SENTRA SV WHICH HAS THE SAME EXACT SPECIFICS. MY CAR REQUIRES 3 TIMES THE FUEL TO DRIVE A SIMILAR DISTANCE. WHEN TELLING NISSAN CONSUMER AFFAIRS THIS I WAS TOLD 'THIS IS NORMAL BECAUSE MY CAR IS OLDER AND HAS MORE MILEAGE ON IT.' NORMAL WEAR AND TEAR OVER A 2 TO 3 YEAR PERIOD WOULD NOT ACCOUNT FOR SUCH A DISPARITY IN FUEL MILEAGE. NISSAN TECH SUPPORT HAS PHYSICALLY GONE TO THE DEALERSHIP TO TRY TO FIX MY VEHICLE AND I SINCE TAKEN IT IN ON FEBRUARY 10 FOR THE 7TH TIME. NISSAN CALLED BECAUSE MY ARBITRATION POC DIDN'T CALL THEM LIKE SHE WAS SUPPOSED TO 4 DAYS AGO SO NOW MY VEHICLE SITS AT THE DEALERSHIP BECAUSE THEY DON'T KNOW HOW TO FIX IT. . MY VEHICLE IS NOT SAFE TO DRIVE ON A PUBLIC ROADWAY OR TO TRANSPORT MY 8YO. I HAVE SUBMITTED MY CASE TO THE ATTORNEY GENERAL'S OFFICE AND BBB AUTO-LINE CLAIM. I JUST WANT TO BE IN A SAFE VEHICLE. I HAVE ALL THE SERVICE DOCS BUT FILE IS TOO BIG TO ATTACH.

BOUGHT 2017 NISSAN SENTRA BRAND NEW FROM DEALERSHIP AND WAS VERY UNFAIRLY OVERCHARGED. I WAS CHARGED $23,014.53 FOR A CAR THAT WAS ONLY WORTH $16,000 AND HAS SO MANY ISSUES. GAS TANK SOMETIMES WILL STOP AT 200 MILES AND WILL NOT FILL UP, SPEEDOMETER SHOOTS UP AND DOWN WHILE DRIVING, SPEED DOES NOT STAY AT A CERTAIN SPEED AND SLOWS DOWN AUTOMATICALLY. THE ENGINE JERKS AND SPUTTERS WHILE DRIVING ON FREEWAYS AND STREETS.
