I bought a certified pre-owned 2012 Nissan Altima 2. 5s sedan from university Nissan in universal city, CA. Throughout its life from when I received car at around 45,000 miles, every couple thousand 5k-10k care engine engine could not accelerate quicker car would begin making engine whining noise. It was never disgnosed as a cvt problem when I would take car to Nissan in warranty repair . During dealership repair enounter mass air flow sensor was replaced. "mass air flow sensor" that has been replaced multiples times throughout its life as well. Car now has a cvt problem and struggles during hot weather and worst if people are in car now.
When driving the car for a long distance (30 miles) there is a whining sound that starts and the car will not accelerate. If the car is allowed to sit and cool down the whining will stop but start back as the engine/transmission heats up. During this period the car will loose power and not exceed 40 miles per hour. This happens when driving throughout the city and on the highway.
My car started making a whining noise while driving it. Going up the hill my car on a highway in the desert when the speed declined it's from 70mph to 45mph, which I tried to accelerate and it was stuck on 45mph, and almost caused the car behind me to crash into me with my three young children in the back seat. A lot of complaints have been made and nothing's has been done. What does it take a life to be taken in order for a recall. The transmissions on these cars are crap. Every time someone walks into the dealership they seem to be well aware but no recall he been done.
When I first bought it I heard a whistling sound and was told it was nothing. I travel a lot and while on the interstate I went from going 75 mph to 30 and it wouldn't accelerate. I would pull over and wait about 10 minutes until I could accelerate. Initially I thought it was the fuel line so I put fuel injector in it and it a couple days later it happened while I was on the interstate again. This has happened to me at least 5 times. I can't even drive it on the interstate. After taking it to the multiple mechanics I was told that it was the transmission and it will need to be replaced.
Driving long distances my car overheats, looses power going from 70 mph down to 40 mph in high speed traffic. I am forced to get off the highway and let it reset itself. It has always made a whining noise during acceleration, and the brakes have squeaked from day one. I have complained to Nissan several times and am always been given lame excuses. Now that my warranty is up they have a solution to my problems. New transmission or overheat converter to the tune of $1600. How convenient they have a solution not that my car is out of warranty!! they refuse to help me or fix my car unless I fork over the money. My car has had problems since I purchased it and there was never any resolve. I purchased an extended warranty as I do a lot of driving. My car was out of warranty 2,000 miles when they miraculously found a cause and solution for my problem.
