Problems with 2010 Nissan Altima POWER TRAIN

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. *tr

When at a stop and starting to accelerate, it's almost as if the power train shifts immediately from low or 1st gear to hi and then vehicle starts to lunge and buck. also, has little acceleration capacity when this happens. *tt

Cvt transmission is warmed up after driving for 20 minutes. once warm, from a complete stop, i lightly accelerate to move forward and the car hesitates like i am not even press on the accelerator so i press harder almost to the floor when the car finally and suddenly accelerates out of control almost causing an accident. this situation happens is a constant problem for the past month. another problem is that you can be on the freeway driving at 60mph and just loose all power and cant accelerate. i took it to the dealership and they say cant replicate the problem and to just leave it with them to see if they check engine light comes on, but i had already explained that the light has never came on. the service advisor stated that if the light doesn't come on and they don't get a "code" from it that they cant fix the problem under warranty even though nissan knows that their is an issue with the cvt so they extended the warranty on the vehicle. *tr

I bought my vehicle in august of 2010. in october we were on our way to florida, and at the end of a full day of travel, aprox 6 hours- we exited i95 in virginia to go to our hotel. when we came to a stop sign at the bottom of the ramp, we attempted to cross a state road to get to our hotel. when i depressed the accelerator the car barely moved and we were almost t-boned by another vehicle. we got to the hotel and after a nights rest the car seemed fine, but the car did the exact same thing the next night. when we got to florida the dealer was unable to find anything wrong and couldn't offer a solution. on the trip back to ny this spring the same problem occurred every day after a long drive, even though we made rest stops during the day. i feel this is a very dangerous situation, not being able to accelerate to avoid a potential accident and do not feel safe driving this vehicle.

I purchased my 2010 nissan altima new at the dealership in april 2010. around 7k miles is when i first noticed the problem. when i am accelerating, between 20-35 mph my car makes a loud nose and hits between 4000-5000 rpms, but it feels like it is losing power and is very slow to speed up. once i hit over 50mph it gets better. i have taken it to 2 different nissan dealerships and they say they can't find anything wrong with it. as a sanity check, i have asked 3 other people to drive my car and they are experiencing the same thing i am. this is very dangerous when turning left at an unprotected light or turning right into traffic. i googled this and see many people are having the exact same issue with the year and model. *tr

Tl*the contact owns a 2010 nissan altima. when the contact engaged the accelerator pedal the vehicle moved very slowly. this happened sporadically and it also occurred while driving on a highway. there were no warning lights illuminated indicating any type of failure. the vehicle was taken to the dealer where they test drove the vehicle but could not duplicate the failure. after running a diagnostic test on the transmission faulty codes were detected indicating that the transmission needed to be replaced. the dealer called the manufacturer and informed them of the failure but was told that the transmission was on back order. they also are not sure when they will receive the transmission to repair the vehicle. the failure mileage was 10,000.

It occurred to me in july 2010. car was 7 months old with mileage of ~7,000 km. there was a problem with acceleration - with acceleration pedal fully depressed engine was revving up to ~2,200 rpm and car barely accelerated like it was slippage in the transmission. switching to sport or manual modes was not effective. there is "high fluid temperature protection mode" described in manual, but there is no warning light/chime that transmission enters this mode. driver not being aware of very limited acceleration can find himself in very dangerous situation leading to fatal accident, e.g. when pulling out in heavy traffic. it occurred several times, never any warning light was on. finally transmission was replaced, but until now (january 2011) nissan did not admit that there is a problem and did not take any preventive action. *tr

Tl* the contact owns a 2010 nissan altima. the contact stated that while driving 30 mph, the brakes and transmission failed. there were no lights illuminated on the instrument panel. the contact stated that she depressed the brake pedal, but the brakes seized and the vehicle slid and experienced an increased stopping distance. the contact stated that once that happened, the transmission failed. the contact restarted the vehicle and the vehicle functioned normally. the contact took the vehicle to the dealer for inspection and they stated that they could not duplicate the failure. the were unable to determine the cause of the failure. the manufacturer was notified and they did not respond. the failure mileage was 3,000. the vin was unavailable.

After driving for extended periods of time (2 hours or more) on the interstate, the vehicle has difficulty recovering from a stop. i accelerate to move forward and the vehicle hesitates. when it reaches about 2000 rpms, it accelerates out of control. i took it to the dealership who could not replicate the problem. they offered for me to bring it in when i am getting off the interstate, but i had to stop before i arrived at the dealership. this occurred around 700 miles. when i'm at stop lights i don't panic, but this is unsafe for interstate driving. nissan will not replace my transmission under the warranty as they cannot duplicate the issue. *tr

My 2010 altima 2.5s has poor acceleration after coming to a stop. this is very dangerous, especially when making left handed turns in front of on-coming traffic. i would press the accelerator pedal all the way to the floor and the car will not accelerate quickly, it's almost like a hesitation or bogg. this issue is worse when the a/c is on. nissan has not issued a recall, but they really need to, because there are many other nissan altima owners with the cvt transmission that are experiencing the same issue. i also own a 95 altima and have never experienced an issue like this, quite frankly i am very disappointed and concerned with my 2010 altima purchase because of this poor acceleration issue. *tr

After a hard application of the brakes (abs activates) and stop, the vehicle fails to accelerate at a normal rate of speed. pushing the accelerator to the floor does not increase the speed of the vehicle. there is a delay before the vehicle will accelerate normally. nissan reports there is nothing wrong with the transmission or the brakes. the process occurs everytime after the abs is activated and rapid acceleration is attempted. *tr
