I purchased this vehicle used with an (Nissan certified) extended warranty with approximately 25,000 miles in 2010. I have had the automatic cvt transmission replaced (under warranty---cvt replaced with new transaxle assembly) on three separate occasions between 2011 and 2013. In early 2013, ross Nissan claimed there was nothing wrong with the transmission and did not replace it, one month later I took it too valley hi Nissan in victorville and they told me that it should have been replaced by ross. The problem is as follows: The car when driven over long periods of time in traffic (1 hour or more), the transmission begins to whine, especially when climbing up hills. On over five occasions the car speed topped out at about 45-55 mph on the freeway and could not go faster on steep inclines. I would have to pull the car over to the slow lane as it would not accelerate past the 45-55 mph until the incline in the freeway leveled off. This has happened several times and each time it has happened, the Nissan dealer would evaluate it and state that the transmission was faulty. The transmission were replaced approximately around 45K, 77K, 109K, in doing the research the following bulletins seem to match the problem that I've been having ntb-13-079 and ntb-12-057 and the one mentioned by the dealer which I couldn't find on this website tsb-ntb10-143A. They all seem to indicate a problem with the fail safe for the cvt transmission fluid protector. I don't understand why Nissan will not replace this issue as it has happened on so many cars. Although my warranty had expired, the problem was never solved correctly. I don't take the car on the freeway, because I am in fear that I will be rammed by another vehicle as the car will not accelerate on occasions when the car is running too hot. The car/transmission is defective.

First, no problems but at regular oil maintenance, they said we had an oil leak. Had it fixed. Engine started stalling. No warning lights. Said had an oil leak of some kind. Fixed it again (so we thought). Happened again two months later - car started stalling. Engine light came on that time. Towed it Nissan. Said had an oil leak. Fixed it (again we thought). Two months later riding down road at low speed, car caught on fire. Got it put out before engulfed because of a gentleman passing by had a cooler full of water. Engine is now totally no good and have another year to pay on this car.

I contact Nissan Corp and file a complaint pertaining to the engine oil cooler. Nissan had a recall on this part back in 2007. They call it the 2007 campaign. The results were giving to me on 6/11/2013 stating that they will not pay for the repairs. I paid 70 dollars to get the inspection at Nissan for them to tell me they will not repair my car. My car is dripping more oil than usually and the issue is the same issue they recall my model car back in 2007. My car is at great risk of catching fire because of the poor quality engine.

I was driving my car heading home from work on the highway in steady traffic and the car wouldn't go just dropped down to zero, however the car was going about 35...I contacted my dealer and they said it was probably bad gas and to bring it in for a check..after going in and paying the 90 plus dollars I was told nothing was wrong..after time passed it didn't do it for a while and around 95thousand plus miles it did it all over again.. took car in and was told nothing was wrong..after driving and finally it wouldn't go anymore and my cars was at about 160 miles by now I took it in and was told that I need to maybe get a tune up after getting a tune up. It drove fine until I drove out of state and the car was driving but speedometer was @0. finally made it home safe after letting car cool on the highway every 50 miles and took back to shop and was told that when gettin a tune up if fluids look ok they aren't changed..so upon finding this out I was told I needed a new transmission @ a different shop put new transmission in and drove fine for 35 plus thousand miles and everything started all over again..took back and was told I needed a catalytic converter a new down flex pipe and a new transmission...I would like to know how to get a car transmission recalled or off the market cause I've never had to deal with a car like this before..I guess that's what I get for stepping out on the Acura and Honda family...:-) please look into this for me thank you!!

Pulled off the highway and merged into a left hand turn lane. When I came to a stop I noticed black smoke coming from the engine block. My car then caught fire and it was later totaled by the insurance company. The previous day I had my car serviced at a Nissan dealership. They changed my oil/filter and changed a part that was recalled (dealing with leaking brake fluids).... coincidence (sarcasm meant)"?"

The engine cooling assembly on the Nissan Altima from 2007-2012 after they reach a certain amount of mileage they begin to start leaking oil. It starts off with just a couple of drips and over time it progressively gets worse. There are a numerous number of individuals online asking if others with the same type of vehicle are having the same problem. So obviously there is a faulty part that was installed on these vehicles that Nissan is avoiding the real significance of the issue. Which can cause your vehicle to lose all the engine oil without realizing it and damaging your engine. I am one of those individuals having the same issue on my vehicle, wanting Nissan to take responsibility for these costs. The replacement of the engine oil cooling assembly is quite costly. This part is a part that can't be damaged by human error, it is tucked away underneath the engine. Thank you
