general problems of the 2012 Nissan Altima - part 1

The sensor was replaced but the light engine light still came back on now the speed sensor is causing the issue. The abs light comes on while accelerating it jumps and jerks.

What component or system failed or malfunction and is it available for inspection upon request. The cvt failsafe high fluid temperature protection mode enacted while I was driving on the highway at speeds of 65 to 70 mph going with the flow of traffic it is not available for inspection upon request because this issue only occurs while you're driving down the highway. How was your safety or the safety of others put at risk? my safety and the safety of my passengers and the safety of my fellow commuters was put in jeopardy due to negligence of the manufacturer of the 2012 Nissan Altima when this occurs all acceleration ceases your foot can be all the way to the floor on the gas pedal and your car will not accelerate and in the fast lane on the highway when this happened I became a sitting duck in the flow of traffic cars are flying by me and my passengers and I can't get enough speed to change lanes and get out of danger due to a failsafe that Nissan put in these cars on purpose they were fully aware of these issues this is a direct quote from the 2012 Nissan Altima owners manual page 5-17 warning when the high fluid temperature protection mode or fail safe operation occurs vehicle speed may be gradually reduced the reduced speed may be lower than traffic which could increase the chance of a collision be especially careful when driving if necessary pull to the side of the road to a safe place and allow the transmission to return to normal operation or have it reparative necessary. Has the problem been reproduced or confirmed by a dealer or independent service center. Unknown. Has the vehicle or component been inspected by the manufacturer police insurance representatives or others. Unknown. Where there any warning lamps messages or other symptoms of the problem prior to the failure and when did they first appear. Zero warning lamps no messages just all of the sudden no acceleration and I am in a very dangerous situation which could have cost many people their lives.

Hi I’m having trouble with my transmission in my car due to a safety feature that Nissan has installed on there cvt transmissions. After driving for 1 1/2 to 2 hour trips my car does not accelerate or will have a slow time gaining speed. Nissan has a high fluid temperature protection mode that basically when the transmission temp gets too high the computer cuts you off completely and intentionally stops you from going any faster. This is a serious issues if your in traffic or driving somewhere on the highway and not able to move to the side of the roadway or to a median. If my car was to completely stop in the middle of the road due to this safety feature, it could cause collisions and life threatening injuries.

Cvt transmission jerking, can’t accelerate. The vehicle has been inspected by multiple mechanics my vehicle stopped accelerating in the highway while everyone was going 80 mph mine dropped to 60 causing almost a collision also my car had turned off because of the jerking was so bad there is no check engine light on at all.

We had a near fatal accident on the highway because the car suddenly lost speed drastically and later on a few incidents won't move up on the slope. My daughter had a hard time reaching home but somehow managed. A quick online research showed many people sharing similar issues due to faulty transmission and sensors. It seems that Nissan is simply hiding behind its 60,000 mile warranty and not addressing and fixing this issue for the consumers and thereby putting lives at risk.

3 times car has decelerated when driving on interstate for 1 to 2 hours. Last time speed dropped to 20 mph when most cars were doing 70 to 80 mph. This creates a very dangerous situation that could result in loss of life if not corrected. Nissan refuses to address the matter and problem is well documented on the internet and lawsuits. Nissan should have issued a recall covering the defective cvt. My college age grandson is driving the car as he has no other option but he is putting his life and friends at risk each time he goes on an extended trip. Nissan should at minimum replace the transmission as a safety issue but have denied our claim. Your help would be greatly appreciated.

Three hours into my drive, I was going about 70 mph and noticed my car started to slow down and was making a noise. I pulled over, got out, checked my power steering fluid. It was fine so I drove off and as I was entering the freeway, I noticed the car wasn't picking up speed again. I drove to the next exit and got off. I literally coasted to a parking lot of an industrial building. After several attempts at trying to leave the parking lot, I noticed I couldn't go up the hill. I waited about 30 minutes, picked up speed and made it up the hill and onto a 2 lane road. I drove to a hotel about 4 miles away, going about 40 mph. I realized that as long as I didn't stop, I would be fine. The next morning I found a mechanic shop, called and drove there with minimal problems. He told me the year, make and model of my car had been having issues with the cvt transmission. He hooked a machine up and it gave him these codes: p0746, p0826, p1778 step motor, p0868. He told me to check for recalls. I was able to drive the car 3 hours back to my house in woodbridge.

Car automatically reduces speed from 65 mph to 35 mph while in motion on highway and will not increase speed when driving at an hour or better at 65 mph or greater. When it autodecelerates it makes a whining noise and will not accelerate again until you turn the engine off and allow the car to sit for 30 mins or better.

While driving for 1/2 hour or more my car loses power this has caused my car to die in the middle of an intersection and almost getting hit. In order to get power back you have to shut the car off and let it sit. We have checked all fluids replaced spark plugs battery alternator filters and it still does this. Upon researching this I have seen other complaining about the same issue with their 2012 Nissan and due to it being a safety harvard should be recalled and fixed.

2012 Nissan Altima cvt transmission issues. Altima has recalled from 2007-2010 and then again after 2012 for the cvt transmissions. Mine is doing the same things and Nissan doesn't have a way for me to check the fluids. The dealership said they can fix the problem for over $7000. I'm in the dealership right now and he says again that he can't check the fluids but that I can replace it if I want but that it might make it worse. The vehicle sometimes doesn't shift and engine revs without acceleration at any speed. Pulling into traffic is very difficult and if I am unable to pass if needed because sometimes it accelerates and sometimes it doesn't.

This was a used pre-certified car, purchased from the dealer in which did not have any issues until its warranty was practically no longer valid. The cars electrical system started to have issues. The issues with the electrical system started with the usb port connection to a cellular device. Sometimes the car will recognize the phone, other times I have to disconnect the usb to phone connection, turn the usb cord around and reconnect a few times for the radio to recognize the phone. After this issues, one speaker went out. Later on, a second speaker went out. I replaced both speakers to find out that it is possible the in-car amplifier blew. After this, the radio unit would at times go completely black, causing me to have to turn the car off and back on. After this, the driver side door no longer locks electronically, I have to lock and unlock driver side door manually but the passenger side does indeed work. After these issues, I noticed the check engine light had come on for a mass air flow sensor. I cleaned the sensor, and the engine light went away. About 300 miles later, it came back on and the car hesitates/bucks consistently with a loss of power once the speed hits about 60 mph. I-75 hills, I can no longer accelerate to maintain speeds. I replaced the maf sensor, check engine light is still on. I had it cleared from o'reilly's since the same code was appearing on the car. After 10 miles sitting in idle, the traction control sensor appeared. 10 miles afterwards this on I-75, the car will not climb hills, drops power, bucks and jerks the car forward and back. I stopped at a part store, turn the car off and back on. Traction control sensor goes away, engine light comes back on with same code reading. I cleaned the throttle body, check engine light is still on. I've read a lot of articles about this, no one has figured out how to fix this.

We were driving up hill in a canyon going 80 mph when we suddenly lost all power. We had only been on the road for 30 minutes before this occurred. We had to pull over and let the car sit for a minute before attempting to drive it home. It happened two more times on the way to taking it back home.

Travelling west on hwy 44 started having trouble going up hills. Put pedal to the floor, and nothing extra. It was starving for fuel. Turned around to go back home, eventually stopping in sullivan mo. While going back I had to gain speed going downhill in order to make it uphill. On two occasions I had a semi rider my rear bumper even though I was in the slow lane. One time while gaining sped down hill, I had to pass the semi in front of me, or lose the speed that I had gained, so I tried to pass on left, as usual, but then the acceleration stalled once again. I then had another semi riding in rear view mirror, and was fearful of what could happen. I was eventually passed by semi on right , I got over, and then the semi on the left passed. Needless to say it was not a good situation. I have seen on-line that there is a class action suit against Nissan, but no recall for the cvt's. In my opinion, this is a must. Even the guy at Nissan had told me that he has heard of many stories just like this. Someone is going to get hurt/killed if nothing is done. Nissan knows of problem, hence the cooling device started in 2013 model. Even this did not fix the issue. Please force Nissan to correct their error in judgement before it is too late. Oh, Nissan does want to fix my issue, for several $$$'s thank you, a concerned driver.

When driving on the highway my vehicle will deaccelerate going from 70 miles to 45 miles, even though my pedal is flush to the floor. This happens sfter I have been driving for approximately 2 and 1/2 hours. I have had this checked out by auto repair and have not found a solution to this problem. When this first happened I was in the fast lane and was barely able to get over to the right shoulder. The second time I had my grandchildren with me and we were basically stranded on the side of the road 2 and a half hours from home with no way to get anywhere for help.

Tl-the contact owns a 2012 Nissan Altima. The vehicle shifted to limp mode while driving the complainant was stranded on several occasions the cvt transmission cooling system inadequate to cool fluids causing the vehicle to go into safe driving/limp mode. The contact stated that while driving for 45 minutes to one hour,the vehicle shifted into limp mode. There was no warning indicators illuminated. The contact stated that the vehicle decelerated from 70 mph down to 20-30 mph. The contact stated that even with the accelerator pedal down to the floorboard, the vehicle failed to respond. The vehicle was taken to miller auto plaza located at 2900 2nd st s, st cloud, mn 56301, (320) 200-2472, to be diagnosed however, the mechanic was unable to retrieve a fault code. The vehicle was not repaired. The contact stated that the failure recurred on a daily basis. The manufacturer was contacted and informed of the failure, case number: 36304669. The approximate failure mileage was 190,000. Piir=y. Ah.

As I was starting to slow down in preparation of taking a turn off the frontage road my car completely shut off, my brakes and steering locked and luckily I was able to complete my turn into a gas station where I immediately put it in park and restarted via push start. , 2 days later this occurred again on a fairly busy street where I repeated the steps to start it again. I am extremely scared to have this happen again on a heavily traveled street causing me to be involved in a collision , I have researched online and see other reports/complaints of the same issue I described yet do not see any recall issued regrading this extremely dangerous defect.

I have a automatic 2012 Nissan Altima w. 130k miles. While driving, my car automatically shifted to neutral and in order for me to stop, I had to place my emergency brakes on. The gear was stuck in between neutral and reverse and unable to move. Thought it was a shifter console, but turns out it was my transmission. In this model car, there is a class action law suit against Nissan for failing cvt transmissions/engines. My failure happened while driving and could have caused a major accident. Due to the miles, I am out of warranty and I do believe that Nissan should be at fault seeing that there is a suit pending.

My vehicle when driving will not throttle correctly so I have to pull over on the road and turn the car off and than turn it back on. After turning the car back on I would rub the engine to make sure it would throttle pass 3. Lately though my car has been turning off while driving which is a big safety for my self and other drivers. Because I have to turn the car of and on quickly especially if im on the freeway.

The mph would register as 60 but I know it was only doing 20. Going around curves it was acting like it want to go but dont go far. It will start but mph wont move, and wont move forward but will backup.

When driving the car for a long distance (30 miles) there is a whining sound that starts and the car will not accelerate. If the car is allowed to sit and cool down the whining will stop but start back as the engine/transmission heats up. During this period the car will loose power and not exceed 40 miles per hour. This happens when driving throughout the city and on the highway.

Complete loss of power climbing a steep grade uphill, almost caused accident sandwiched between two 18 wheelers also going uphill one of which had to swerve sharply to avoid hitting us. Cvt transmission likely went into fail-safe mode, same thing repeated multiple times on steep winding climbs on mountain highways. Very dangerous situation with engine cutting out and loss of power. Nissan has issued cvt recalls and extended warranty on models up to 2010 but the problem is still there in this 2012 Altima and in many other complaints about the cvt on later models. Nhtsa should get Nissan to extend its recall/warranty to models after 2010 judging by the many complaints being reported about the same loss of power issue with the cvt.

While driving on the interstate I had my cruise on for around 35-40 mins, got off my exit and noticed even if I mashed my gas my car would not pick up speed, I pulled over while coasting, shut it off for around 10 minutes, took off again and it done fine. This has became a weekly thing . I've called with questions and no one can help me!!!!.

When I took the car up to 85 miles per hour and I drop speed and I tried to pick speed back up it wouldn't let me go over 40 miles per hour I had to pull over cut the car off and then started back up and then it let me proceed to go where I need to go and it acted normal this is the second time this is happen.

Cvt transmission on the Nissan ultima 2012 has been had given me a lot of problems for the past 6 months. Upon seeing reviews on the internet in hearing a lot of complaints due to the transmission problems with the Nissan baltimore frome yes before the 2012 model up until now that something has to be done to correct this problem with Nissan dealers to fix this brow with all the alter most this having a strong with faulty equipment. It is very dangerous to drive by losing power especially if you only in a state will call several accidents due to losing power to upgrade and wanting noise is just creates a big problem moon in a state if you drive-in in your fewer in a major city with the the vehicle slowing down without your control.

My car started making a whining noise while driving it. Going up the hill my car on a highway in the desert when the speed declined it's from 70mph to 45mph, which I tried to accelerate and it was stuck on 45mph, and almost caused the car behind me to crash into me with my three young children in the back seat. A lot of complaints have been made and nothing's has been done. What does it take a life to be taken in order for a recall. The transmissions on these cars are crap. Every time someone walks into the dealership they seem to be well aware but no recall he been done.

Vehicle was in motion on the highway and after two and half hours of driving could not accelerate past 45-50 miles an hour and stuck on this speed even with the gas pedal being pressed down to accelerate. I had serious safety issues with this on the highway in regards to ascending hills and had near serious encounters with trucks and other vehicles on all incidents I have had to drive more than that duration. I am on a website called cargurus and have a lot of Nissan 2012 Altima owners with the same year, make and model having exactly the same terrifying experience. I have called Nissan about this and that they should do a qa of their call logs and check other complaints from other customers and all they could say is "there is currently no recall on your VIN". Informed them about medicine after death not possible and problems like this with frequent complaints by customers should be investigated and not ignored till people start dying before there is a need to fix this or issue a recall. The gear box and cv axle based on what I have read may be the cause of this. I am not a technician but this is a very serious safety issue that should be investigated. Every time you are in a car on the highway on long distance journey with this car your life is on a live wire because of this gear box issue. I have also been to the dealership in south holland IL for this and was told to call Nissan and complain about this which I have done. I will appreciate your looking into this please! thanks.

Takata recall. I was traveling on the interstate, in heavy traffic, when my car began to slow it refused to maintain my speed or accelerate at all. I had to pull into the median to avoid being hit by an 18 wheeler. I had my sister and two of our little kids in the car with me. This is not the only time it has done this it has done it several times now and the mechanics can't find anything wrong. I have read several places where others have had this same issue. . . . I believe their is a manufacturer default with either the acceleration or transmission. . . . It just revs up sounds like it's doing something but not increasing speed. I have noticed that it occurs mostly after I have been traveling a while. . . Like about an hour and a half or so.

While in motion, the vehicle begins to drasticly slow down from speeds of 60 to 70 mph down to 20 to 30 mph. This usually happens during the day after driving for an hour + and in any kind of incline road. At hard inclines I can bearly drive upward even hhaving to come to a complete stop. The rpm gage begins to jump rapidly to 5 and 6 rpm when even slightly pressing the gas peddle, and once it adjust , the vehicle will not go more that 3 rpm while still at a mph slower than 30. This will stay for the remainder of the drive until I have stopped and turned my vehicle off for a significant amount of time. Tbis began happening at 100,000 miles and now at 150,000 miles it happens very frequently. I feel this is unacceptable, and clearly very unsafe for driving long distances on large highways, when my vehicle should work as it should.

The contact owns a 2012 Nissan Altima. The contact stated while the vehicle was operated between 60 and 70 mph, the vehicle experienced an abnormal deceleration. The contact also stated the vehicle made an abnormal noise. The vehicle was taken to central valley Nissan located at 4530 mchenry Ave, modesto, CA where it was diagnosed that the cvt needed to be replaced. The manufacturer was notified of the failure. The failure mileage was approximately 18,000.

While pulling into a parking place at a restaurant all of a sudden my wife heard a loud noise and surge from the engine propelling the car forward and over an embankment fortunately for a few trees and god's help my wife is thankfully still alive the embankment had approximately 100' drop this has never happened before the sound coming from the engine she still hears, not sure once the car is fixed if we buy another Nissan Altima or even continue to drive this one, something caused this car to surge and it definitely was not her foot,.

2012 Nissan Altima 2. 5s sedan, purchased new plus extended warranty with 3 miles on it. At 64k miles while driving on the highway after about a. Hour at normal speeds on a hot day the car started making a whining noise from the engine compartment. The vehicle became sluggish and the speed reduced to 60mph. The rpm gauge began to rise ant the car began to decrease it's speed eventually descending to 20 mph while the rpm gauge fluctuated from 2k to 5k rpm. The gas pedal was non responsive except for a louder whining noise as it was pressed . We pulled over for a while and the vehicle went to normal. This exact same issue happened 2 more times before we arrived home. The dealer responded stating a new transmission was needed but not covered they said my warranty was not valid. I complained, they contacted headquarters I guess and stated to me because the car was under 70k miles the company would pay partial for the repair but my out of pocket expenses would have been about 1200. Not only did I think this was unfair but I also didn't have an extra 1200 lyng around. So unfortunately I've been dealing with this issue for years car drives fine for about 40 min. So no long commutes.

My Nissan Altima 2012 has significant reduction in speed while taking trips less than 40 miles. Driving on fast lane on highway about 70 miles then all of a sudden it reduces all by itself to 35-40 mph and I almost got into in accident because I did to know what was going on but had to get off the onto the side of the highway.

While driving on the interstate to FL from ky at around 65-75 mph the vehicle would not accelorate past 3000 rpm's. Going up hills was the worst, cars would pass and our vehicle would slowly decline in speed. Pulled over to check the car out and after if cooled down it when back to working okay but after another hour on the road it done the same thing.

After driving at 70 mph for several hours, the vehicle will no longer accelerate and slows down. The vehicle needs to sit for a period of time before it is able to accelerate again. This issue had occurred before 8k miles earlier and had the cvt cooler replaced under warranty.

Today was the second time I've experienced this dangerous issue while driving on the freeway for about an hour and a half long. My car began to lose speed and would not accelerate above 60 mph. While I had the gas pedal down completely all the way to the floor, as the car could not gain speed. I could have been in a serious accident with all the traffic on the freeway, I had to merge over to the far right for safety. I drove my car immediately after to Nissan so they could verify this issue. They failed to help me in any way recommending I invest in a cvt cooler, due to not being covered under warranty anymore. A couple months back when the car was still under warranty I took it to Nissan with the same issue, at that time they stated they could not detect an issue. But now my warranty is up they're suggesting what the car needs. I'm very upset with how dangerous this can be and how careless Nissan is. It's like they are just waiting for someone to seriously be hurt in an accident to then do something about it.
