2012 Nissan Sentra power train problems

“Our nissan Sentra with 106K miles the car lost nearly all power as my son was turning onto the freeway. He could only drive 16 miles an hour and it was hopping and jumping through a 8 lane freeway/highway intersection while he tried to get into a parking lot off the road. He turned it off, waited 5 minutes, and turned it back on, but it was still slowly hopping and jumping. After another 10 minutes my husband drove it for about 10 minutes and it operated normally. This same behavior happened in 2019 with 82k miles at a large intersection. It suddenly lost power and slowly hopped through the intersection. At 60k the cruise control buttons on the steering wheel quit working. When we asked the Nissan Dealership about it, we were told that was typical and it would slowly lose all the functionality of the steering wheel controls. All the functionality was gone by 70k miles. We have learned that Nissan's transmissions are very problematic and these situations are typical as you get closer to 120k miles. We planned to have this car for several more years. If we sell it and buy a different car we are out several thousand dollars or if we keep it we will likely have to…”

“The Transmission is making a whining nose and smells terribly bad! When driving on the interstate and parkways; after the car reaches 60 -70 miles, the car starts shaking and slows down; almost coming to a complete stop and we have to either get over in the slow lane and/ or sometimes, we have to pull over, off the interstate, because it has came to a complete stop and would not accelerate and/or move forward ! We sat there for an hour waiting for help/ and I called my Granny! When she got there; she checked the oil, added a quart of oil! After sitting there for over an hour; the car accelerated and we drove onto a side road and drove it slowly back to the house! WE took it to Unitires on Charolette ! He told us, the whining noise appeared to be the Transmission ! He repaired the wheel bearing , which stopped some of the shaking; but not all of it!”

“While driving on the freeway pulling approximately 70 miles per hour, my car will begin to shake violently, continuously decelerate and my RPMs drop significantly. I am unable to go over 55 miles per hour when this happens. This has happened to me a total of four times now within the last 2 months. I had my car take this one auto repair shop in which my spark plugs were changed out a brand new air intake hose was put in my coils were changed out and everything. Today while driving on the freeway, going 72 mph my car decelerated and would not go above 55. This is a major safety issue considering I drive on the freeway a lot. I just paid $970 to have my car fixed and can't continue to pay to have the car fixed along with still paying a car note and insurance on this car. Well researching transmission issues I came across this page when filing a complaint. I looked to see if there was a recalls on my car and noticed that there is not. My VIN number is [XXX]”

“While driving at around 70 mph on the highway the car suddenly lost power and was no longer able to accelerate. This issue persisted for the duration of the drive and has happened now on more than one occasion. There were no warning lights or messages before or after the car stopped accelerating and this very nearly caused and accident when the car wouldn’t accelerate during a lane change even with the gas pedal fully depressed. After a few minutes of no acceleration the car also begins to accelerate suddenly and without warning. I haven taken the car to an auto shop and they were able to pull codes that indicate an issue with the transmission. I have not yet paid for the issue to be fixed and the car is available for inspection upon request.”

“Vehicle transmission appeared to slip from gear causing vehicle to lose power while in heavy interstate traffic at 70mph, vehicle lost acceleration and began to slow then "bucked" jolting vehicle several times almost suffered rear collision from following cars. Upon stopping to check fluid in transmission, stick read full for hot.”
