2011 Nissan Sentra with 80,000 miles and the cvt transmission is making a high pitch noise when accelerating. It increases in rpm but doesn't increase power. Nissan is aware of the issue with these transmissions but refuse to do anything about it if the car is out of warranty. This could be very dangerous if trying to pass another vehicle with oncoming traffic. This and many other problems with the cvt transmission are all over the internet. They extended the warranty for earlier models but won't do anything for newer ones. When I called and opened a complaint with Nissan consumer affairs they called the next day and told me there would be no assistance from Nissan and as far as they were concerned the case was closed. I took the car to a Nissan dealer and the vehicle tech said he thought it was the cvt going bad. He said they have a lot of problems with cvt's and his opinion was he wouldn't own one.

The following problem with the car can potentially cause bodily injury. Please record and compare with similar complaints. When the vehicle is warmed up (after about 20 minutes of driving) and the gas pedal is pressed genteelly, it experiences severe rocking back and forth motion during the driving. It unexpectedly accelerates and then unexpectedly decelerates, occasionally to almost complete stop, repeatedly. The tachometer reading will suddenly jump to above 3000 rpm and swiftly jump back down below 1000 --€“ all within 2-3 seconds. Then it returns to normal range at 1000 -1600 rpm depends on amount of gas pedal applied. The car accelerates and decelerates in sync with the rpm changes. When the car is decelerating, the car makes squeaking noise and it feels like the brakes are applied to the maximum. If the gas pedal is continuously pressed at the same level, above symptoms repeat at uneven intervals, frequently in between every 5-10 seconds. If the gas pedal is pressed more, the above symptoms get worse with larger range of rpm changes, louder noise, and more severe jerking. When the vehicle is stopped with the engine on, it is hard to start moving and accelerate -- lack of power and the rpm suddenly jumping up and down. According to the dealer, a coil inside the transmission is at fault and the connection between the engine and the transmission was assembled wrongly.
