Transmission Gear Slipping problems of the 2010 Nissan Altima

The cvt transmission started shifting hard a few months ago. Then about a month ago the transmission started slipping. I exited the freeway and came to a light. Turned left and was in the middle of the intersection when the car would not go. I was nervious and pushed then pumped the gas and the car would not go. Then out of the blue it took off with out my foot on the gas. I had the transmission fluid changed. Then a few weeks latter I was driving 75 (speed limit) with cruise control on then the car started loosing power, 65,60 55. I accelerated the car and it just would not go faster. I was able to stop it with the cruise at 55. With flashers on could have been killed. Started my research and found that Nissan has extended the warranty by doubling it from 5 years/60,000 to 10 years/120,000 miles. My issue is my car is only 6 years old with 128,000 miles and Nissan has my car in their shop and will not fix it. I believe the cvt transmission needs to be recalled before someone get killed. I have very service record since the day I bought the car with 12 miles on it. The car has been well maintained.

Purchased my new Altima 3. 5 a few months ago. Had a problem the second week, seemed like the transmission was slipping. After stopping at a stop sign, I accelerated but the car wouldn't move. Had to accelerate a lot to get the car to move very little and very slowly. Had I been pulling out in traffic it could have been a disaster. The problem occurred a few times as I parked in a parking garage. Upon returning to the car hours later the transmission seemed fine. Months later after a 3 1/2 hour drive on the highway, I got off the highway exit and the same thing happened. This time it continued to happen at low speeds, the car only accelerated properly at high speeds. The following day (Monday) I drove the car to my Nissan dealer to check out the problem, I never had any warning lights at all. They ran tests, found nothing, road tested and determined I had a defective transmission. Brand new car. This defective transmission could have resulted in serious injury or death to my family and myself. Nissan is replacing the transmission as I write this report, but this needs to be looked into to prevent others from serious accidents. I was lucky.

2010 Nissan Altima making a loud clunk noise. Consumer states the noise happens only when it's cold outside, the vehicle is cold, and at speeds 30 mph and less. The consumer stated the noise was so bad, it felt as though the vehicle was going to stall. The consumer also stated it felt as though the transmission was slipping. The vehicle would drag/sputter. The slipping was sometimes accompanied by a rattling noise coming from the underbody which lasted for 3-4 seconds. The dealer was unable to duplicate the problems the consumer experienced.
