The incident happened while driving the vehicle home from the dealership upon purchase. The milage on the car at that time was 290 mi. The car went into a bucking/jerking/lunging when we started to accelerate from a 35 mph zone to a 55 mph. Over the next days and weeks it continued to occur while accelerating and also while maintaining consistent highway speeds. It also regularly experienced a rumble strip feel/sound when accelerating off a stop when traveling 20-40 mph. At first it happened every few days but within a month became a nearly daily experience. Nissan acknowledged that it is a problem with the transmission, but have been unable to fix our vehicle after multiple attempts. About a month after owning the veh, they performed a computer update to attempt to fix but the fix failed. A month after that they replaced the torque converter to attempt to fix. That fixed the jerking/bucking/lunging but the rumble strip shudder still persists at random times when accelerating around 20-40 mph. It happens daily for a week or so... sometimes once a day, sometimes multiple times a day... then it won't do it for a week or so... then it returns again in the same pattern. Our vehicle now has about 8200 miles and the problem continues. Nissan has failed to fix our car despite an ongoing transmission problem.

Purchased this vehicle in March 2013. Since purchase experienced numerous times transmission problem that manifests itself as vehicle shuddering when trying to make turn at low speed or from complete stop. This also happens when trying to accelerate to go onto highway, vehicle would shudder and can not accelerate until foot is taken from the gas pedal and gas pedal pressed again. I brought this to Nissan usa attention and spoke to the dealership several times. Vehicle was evaluated at the dealership service center and we were notified that the problem can not be duplicated. I tried to explain to the technician that in order to duplicate problem this vehicle have to be driven for several days if not weeks on daily basis since sometimes problem happens every three days, sometimes it happens three, four times a day. I have a feeling Nissan is trying to hide serious flaws in the design of their new Pathfinder and it is simply refusing to take care of problems. This is serious safety issue and I hope we will not wait until someone dies in the accident until Nissan takes necessary steps to fix their cvt transmission.

I purchased a new 2013 Pathfinder for myself on 4/18/2013. I started noticing a slight shudder on take off from a stop in May. We mentioned this to the dealership in early June and the immediately acknowledge there was a problem with all the new model Pathfinders. The fix was a torque converter for the cvt but the parts were on back order with no known eta. In late September they called saying they had the part and told me to bring it in for the repair. When I came for my scheduled appointment a couple days later they turned me away stating the torque converter was found not to fix the problem and they needed to completely replace the transmission. Again, the parts were on back order and no known eta. The transmission replacement was finally done 10/24/2013 and we started feeling the shuddering right away. I thought it was the transmission breaking in. The problem is much worse now with the car losing complete power and causing potential accidents. I have a 12 month old riding in this vehicle. We are currently requesting Nissan to repurchase the vehicle because the dealership says there is nothing they can do.

We purchased our new 2013 Nissan Pathfinder on 03/16/13, from tustin Nissan in tustin, California.. at approximately 3000 miles, the vehicle's transmission began to shutter and jerk the vehicle when driven at approximately 15 to 20 miles per hour. Initially, it occurred not too often and we did not think much of it. The shuttering got much stronger as time went on and became more often. During these occurrences it appeared that the vehicle lost power which caused the vehicle to slow down. This created a safety concern due to nearly being struck by vehicles a few times while pulling out of driveways and merging into highway lanes. Its a safety issue and Nissan needs to fix. Took the car to the dealer and said we can't duplicate the issue. So not sure what to do.

- Irvine, CA, USA

While making turns from side streets into main roads trying to accelerate and merge into oncoming traffic the car will briefly accelerate then power will drop out, RPM's will jump to 4000-5000 with no acceleration leaving me in the main road with no power to accelerate and stuck at between 25-35 mph. Only way to correct problem is to hit the brakes and re accelerate. This has almost caused several accidents and has happened multiple times.

Driving along at a relatively slow pace around 45 mph the transmission shook and shudders. It feels like going over rumble strips. The vehicle has done this multiple times this weekend at 25 mph and at 45 mph. The vehicle is 2.5 months since purchased new. It has been to the dealer for this issue 500 miles ago. The transmission was replaced with a factory remanufactured transmission and is starting to do the exact same problem it had prior to the replacement. Nissan had the vehicle for 23 days to replace the trans and additionally had the vehicle for 3 days to repair the a passenger air bag seat sensors when it failed during the delivery. Nissan is aware of the problems with the Pathfinder transmissions that the buyers are having and continue to sell these vehicles to the consumers. This was a very expensive purchase and the expectations were high. Those expectations have been lost Nissan has refused to refund the purchase price to me or replace the vehicle. This is my second report to NHTSA. My first ODI was 10547158. I have sought legal counsel. In my opinion Nissan is negligent in selling these vehicle when they are aware of them having these problems with the transmissions and they have no fix that adequately solves the issue. I will return the vehicle to the dealership. This is not right that a brand new vehicle has to go back to shop for more downtime after already being out of service for 26 days out of the first 45 days of ownership.

The 2013 and 14 Pathfinder have a faulty cvt transmission that Nissan can't seem to fix. The cvt will "judder" between 18 and 35 mph. It feels like riding over rumble strips. This is a problem as the car can not accelerate during the judder and it is also an unexpected behavior which could cause someone to panic. For instance, if you try to pass or pull out in front of someone, you may find the car not moving. Nissan has tried multiple fixes for this - started with tcm reprogramming, then torque converter replacement, then entire cvt replacement. Many vehicles, like mine, are on their 3rd cvt. Worse, they are replacing them with remanufactured cvts. This is a serious defect that has safety implications. I pulled out in front of an oncoming vehicle with plenty of distance/time if my car was working properly but when my cvt started juddering and my vehicle slowed, I was almost hit.

Purchased vehicle Jan 2013. Vehicle shudders continuously when traveling at constant speed around 40 mph. Also shudders violently and loses power when turning at low speed, approx. 5 to 10 mph. Source feels to be transmission. Happens every time driven.took back to dealership where purchased May 2013. Technician drove it and said they couldn't feel anything wrong. Took to another dealership in October. They reprogrammed the ABS system because they said there was going to be voluntary recall issued soon. That had no effect on problem, still as evident as ever. Now faced with third trip to shop to try to get something done. Seems to be common complaint based on what I read.

My wife purchased her 2013 Nissan Pathfinder on 04/06/13, from metro Nissan in montclair California. The vehicle had only 35 miles. At approximately 3000 miles, the vehicle's transmission began to shutter and jerk the vehicle when driven at approximately 20 miles per hour. Initially, it occured not too often and we did not think much of it. The shuttering got much stronger as time went on and became more often. During these occurances it appeared that the vehicle lost power which caused the vehicle to slow down. This created a safety concern due to nearly being struck by vehicles a few times while puling out of driveways and merging into highway lanes. Its a safety issue and Nissan needs to fix. On 10/29/13, I dropped off the Pathfinder at metro Nissan, with aproximately 6281 miles. I test drove vehicle with a technician. The technician observed and felt the vehicle shutter and tremble at approximately 20mph. The transmission was replaced, due to internal damage, with a new transmission. The new transmission appears to be fine but I have read numerous reviews online from around the us with similar problems and concerns. Some have had transmissions replaced and problem have continued. My question is, what is Nissan going to do to fix this problem. Its truly a safety hazzard and my wife and I are concerned that the problem will return. Nissan or dealer does not seem to have solution or fix for the problem.

Transmission shuddered, squeaky noise in the brake system with my foot off the brake pedal.

Upon accelerating, I noticed jerking/shuttering. This has happened 2-3 times since then. Taking to dealer tomorrow.

Incident happen multiple times from July 20th 2013 up to September 2013 only in hot days with outside temperature around 85 degrees. All situations were very similar. I will describe just one. I was trying to merge to traffic from right to left. I moved slowly around 25 mph and I sow that I can merge to line so I accelerate lightly to around 30-32mph where RPM was around 1000-1500rpm. When I was changing lines car start shake like I'm going trough slow down strips, I remember speed because I got scared and I took look to dash if engine light is on and if engine is shutting down. I saw RPM still up and car started move normally after 1-2 sec. When I pressed accelerator. I thought that car will stop and I will get hit by car coming from rear. I had 2 years old daughter in car with me at that time. No so funny Nissan. I visited dealer 2 times. Dealer tried to replicate issue but they did that at morning when is not so hot. They couldn't replicate it and they sent me home with nothing because Nissan didn't released recall for my VIN.

My husband and I purchased the 2013 Nissan Pathfinder, November 2012. We traded in our Chevrolet Tahoe and decided with gas prices increasing we needed a vehicle that we can save a little on. We put our trust in Nissan. About 11 months after purchasing, I was leaving work and backed out of my parking space proceeded to the stop sign. At the stop sign I accelerated and it moved forward a few feet, then it made a loud noise. Before I knew it the car was on, but would not move. Would not move forward or in reverse. The good thing is I had a person behind me that noticed I had car problems and pushed the car out of the lanes of traffic. Got the car towed to Nissan dealership, and they just informed us that they could not figure out why the card is not working. The transmission is going into gear, just not moving. Now their shop manager has decided to replace the entire transmission. This is one week that we have been in a rental....should get our car Friday. Will my car ever drive the same again with a new transmission ?

We, like many other owners, are having problems with the cvt transmission in our 2013 Nissan Pathfinder 4X4. At low speed acceleration, transmission shakes violently and power is lost -- cannot speed up. Also happens at high/highway speeds. It is an intermittent problem but a dangerous one, both when trying to speed up from rolling start or when passing/accelerating at highway speeds. I have contacted Nissan, taken to a dealer where they say they will replace torque converter. I hope this will help but most other owners reporting similar issues say these are not fixes and problems recur. Will report back. Beyond the transmission issue, our hood also buffets significantly at highway speeds. It visibly shakes and when I asked the dealership to fix, they said they could not recreate and it wasn't dangerous.

I just filed a complaint last week regarding my air bag on my 2 month old Pathfinder and this week I had trouble with my transmission. Approximately one month ago when I was accelerating onto the highway my car seemed to get stuck in second gear and would not go above 30 mph. The rpms were going up to 7000 without any additional power. This only lasted for about 10 seconds. The dealer checked out the car and said that nothing was wrong with it and that it may have been a communication problem with the transmission. It happened again this week, again trying to merge onto a highway. The speed limit on the highway was 55 and my Pathfinder would not accelerate past 30-35 miles per hour for 1/4 to 1/2 mile. It is quite disconcerting when a tractor trailer rides up on your bumper going at least 55 miles an hour and you have no power to accelerate to get out of the way. Once again, no warning lights came on the dash so I am sure that when I take it back to the dealer next week they are going to once again tell me that nothing is wrong with the vehicle. Obviously this is a safety concern when the transmission can just stop responding like that. I don't know how Nissan can use the excuse "because it didn't trigger a internal warning with the computer, nothing is wrong." Clearly something is wrong and since Nissan really needs to address this issue.

Received my Pathfinder back after 15 days in the shop for replacement of ABS modulator and shuttering in the transmission. Nissan service dept. Told me they did a modification to the transmission to stop the shuttering. Service manager told me there was still a shutter at around 20-30 miles an hour and that was just how the vehicle ran. Left for a 500 mile trip day after picking up for these fixes. On the hwy. It lost power on hills and shutter was harder then before. RPM's were higher than normal which decreased gas mileage by 5 mpg. Called service dept. And they told me to take the overdrive off. Vehicle did run slightly better on the hwy. But once on surface streets it would hesitate (not move for 2-5 seconds) and then lunge forward when taking off from a stop. Other times it wouldn't move at all. When in reverse it would not move then would jerk backwards. Also would roll forward on a slight decline even when in drive or reverse. Finally on the way back home the vehicle's RPM's went to 5000 and got stuck there, check engine light came on. We pulled off the highway at nearest exit. On the off ramp vehicle stop moving. Fortunately there was no one behind us. Had vehicle towed to a Nissan dealer and they said the transmission has 3 modulators that went out. Vehicle has now been out of service for more than 30 days and the transmission is back ordered. Nissan corporate has contacted me and wants to do a repurchase or replacement. Replacement would only mean that we would be getting the same defective transmission but in a different Pathfinder. Repurchase means we are out a lot of money.

I purchased my Pathfinder in November 2012. At about 1000 miles into ownership (less than a month, my vehicle started shuddering and acting like it was going to stall. When I took it in for the first service they told me they checked for it and couldn't find anything. Then they asked me to bring it back in for a computer update. It still shuddered. At the next service repeat the same scenario and they couldn't find anything again. The shudder is progressively getting worse at this point. When I took it back for the 3rd service I told the dealership again and was told the same thing again. Repeat one more time in 9/13 and they told me I needed a new transmission. A new transmission was put in on 10/7 and I picked it up on 10/8. I left for a beach 800 mile trip on 10/9 and the shuddering is still happening and now when I turn my wheels while slowing down (entering my garage/braking in a curve) the brakes will not hold and the vehicle will surge as if out of control. If I leave it running for a 10 or so minutes in park then try to put it in drive the vehicle tries to surge away from me as if I cannot control it unless holding the brakes down. Last week the vehicle jumped across 2 lanes of oncoming traffic then quit. I quickly started it again and jumped into a parking lot. The dealer picked it up and told me they could not duplicate the problem and would do anything to help me. In fact they said it was driver error. The last I heard when you press the gas the car should go and when you press the brakes the car should stop. It is now sitting in the dealer parking lot because I am extremely afraid of it. They told me it was just fine and to come and get it. I almost died last week in it and it is not safe. The dealer will not help me nor Consumer Affairs at Nissan are helping me. No one should be driving this vehicle. So now I am out $44,000 for an unsafe car.

Transmission shuttering problem: Traveling on los osos valley road, slo ca. Accelerated out of a turn to about 25 miles per hour; when the vehicle shuttered 5 to 6 times. Minimal loss of power, and then resumed to normal. Feels like vehicle is going over speed bums, but there are none. This 2013 Pathfinder is new, with 2200 miles on it. This is now the fourth time this has happened. The shuttering seems to happen when coming out of turns, while accelerating up to 30-35 miles per hour. Nissan needs to come clean on this issue. So far, they are playing "take into a authorize service dealer". most likely, Nissan knew of this problem and is hoping that all new 2013 Pathfinder owners will act as a "vehicle delivery service" to resolve Nissan transmission problem. Not quite..

This vehicle would buck and jump due to the transmission factory problem, we with dealership and they rebuilt this original one and told me there were problems across the states. This lasted about 3 weeks I went back to dealership and they had to have a service technician drive it with computer attached to throw a reading this took about 4 days. The Nissan main headquarters agreed to put a new one in and said they had a fix this was close to Sept. Holidays transmission box came but had a motor in it, then I had to call back headquarters because they were a month behind on fixing the ones they were ahead of me, so I had to get upset with them and they sent one in about 2 days. Now that has been about 3 weeks and my vehicle is jumping and bucking again, headwater will not fix this until a technician drives the vehicle again and computer must throw a code. I am tired of having to wait on a fix I am making $547 payment for 7 months and it has been in the shop most of this time.
