Notes: The 2005 Nissan Altima has two fairly significant problems with the floor pan rusting through & motor mounts breaking.

Altima owners report that up to a basketball-size hole develops under the floor mats where the floor pan metal rusts through. Average repair cost is over $1,000.

The broken motor mounts are less of a problem - they break at ~75,000 miles average & it's $400 to fix. Still, motor mounts should not break!

2005 Nissan Altima SE-R man transmission. The clutch pedal sticks to the floor. This has happened twice in a one year period. I had the clutch replaced once and the slave cylinder once. The pedal is starting to stick again. It happens when your driving. I drove to a movie, went to leave and the pedal stuck to the floor. When the pedal sticks it will not come out or go into gear. I had to pull over, slam it in neutral and ended up driving home in fourth gear. I have been on several Nissan forum sites and there are a lot of SE-R owners having the same issue.

The clutch in my 2005 Nissan Altima sticks to the floor; no pressure what so ever. This has happened at least 3 times before. This time it happened on a bridge in a one way stand alone lane. It had lost more than 50 percent of its pressure. Good thing I was wearing sandals. Was able to lift the clutch with my toes and make it off the bridge. Once I got off, the clutch was not responsive what so ever. I pulled over and parked with the car off for 20 mins. Clutch started to work againża miracle. Last time, it took over 5 hours for the clutch to start working again. If I was in traffic or had to make an a brunt stop, braking without the clutch would have been disastrous.

The contact owns a 2005 Nissan Altima.the contact stated that when depressing the clutch while shifting gears, the clutch would drop too quickly to the floor making it difficult to change gears. The vehicle was taken to an authorized dealer approximately six times and they were unable to duplicate the failure. Approximately three years later, the contact experienced trouble trying to shift into neutral gear when the clutch pedal moved too quickly to the floor. After repeated attempts she was able to shift into second gear. The vehicle was taken directly to an authorized dealer where the spring retainer was replaced. A bearing-clutch and limited slip were also installed. Approximately 2 months later the failure began to recur. The vehicle was again taken to an authorized dealer where it was in the process of having the failure diagnosed. The failure mileage was unknown and the current mileage was 40,200.

Before I replaced my 2005 Nissan Altima 3.5 SE's engine, transmission, injectors, mass airflow sensor, throttle body, and clutch, I was having issues with the clutch losing pressure. After taking the car to Nissan I was told I needed a new clutch. I had it replaced along with everything else shortly after with other major engine repairs due to a blown motor at 100,000 miles. Now my car is back in the shop and after two months with the same issue among other electrical problems. I lost pressure again yesterday and dropped my car off this morning. They want $370 to replace the clutch slave cylinder. After reading all of the complaints, I feel that they are dead on track with this being a safety issue. This isn't the first time its happened to me either. Why hasn't this issue been resolved by Nissan, obviously this is a trend. Do I have to get in an accident with my kids in the car before something is done about this" maybe it will be your family we crash into"!! California lemon law needs to change because apparently very little is being done with recalling defective automotive parts. 3 time iraq war veteran! -usmc

1. Nissan Altima S 2005 manual. Was driving in a heavy traffic for about 30 min with A/C working. Clutch pedal became very light and then stuck to the floor. The car was left on a gear. Hardly avoided accident by braking with working engine and then shutting down with key. 2. it occurs again when the car was left in hot sun after driving in a traffic. 3. did not do anything yet. But will go to mechanic if it occurs again.

I own a Nissan Altima SE-R, I purchased the car pre-owned with 42K miles on it. After having the car for just a month the clutch will sink to the floor and I will not be able to shift the car into any gears. This has been an on going problem since I've owned the car and its going to be 2 years of owning the car this summer. Many of the times the clutch has lost pressure going over bridges and stopping to pay tolls and during traffic. How can I operate my vehicle correctly if the clutch keeps loosing pressure because the master and slave cylinder looses pressure. How safe is that for not only myself but other motor vehicle operators on the road.

The contact owns a 2005 Nissan Altima. The contact stated that the gears were grinding and the clutch pedal fell down which made it impossible to shift gears. He had to drive onto the emergency lane or apply extreme pressure to the brake pedal until it began to function normally while driving approximately 25 mph. The failure occurred more frequent during the summer. The engines oil pressure decreased to 10 psi. He took the vehicle to the dealer who stated that the required oil pressure was 14 psi. The dealer also stated that they could not offer any assistance after they replaced the oil pressure sensor. The dealer replaced the master cylinder clutch in 2008 but the failure continued to occur. The vehicle had not been repaired when the complaint was filed. He had not called the manufacturer to-date. The current mileage was approximately 36,200. The failure mileage was approximately 160.

When car is cold, clutch has trouble, this has been since the day I got it at 45,000 miles. The clutch has always had to go the floor to engage and I was recently told by a mechanic friend of mine that is dangerous.

The clutch will lose pressure leading to the inability to shift. Once this starts to happen, it will happen randomly until the car sits for several hours. This causes unsafe situations at intersections and on the highways during traffic. I have experienced this since I bought the car and experience the problem most often during hot days with lots of stop & go driving. Over time/mileage, the condition becomes more common. The dealer eventually replaced the master cylinder to correct the problem. It fixed it for awhile then it started happening again. Until the condition was happening enough for the dealer to detect the problem, they would not do anything. They eventually decided to replace the master & slave cylinder again.

I had the clutch drop to the floor, get spongy and really low when I'm driving. It happened several times, each time costing me money to sit up in a hotel or miss work many states away. Every single time I take it to the dealer they tell me there is nothing wrong with it.

I own a 2005 Nissan Altima ser with a known clutch pedal issue, it was fixed under warranty 2 times and the 3rd time they refused because I was a few miles past the 35K mile warranty even though the repaid was within the 12K miles that it is warrantied for, I had to go elsewhere to fix it because I need my car. I thas happened 2 times since than where I have to keep purchasing pedals because the welds on the pedal do not hold, it is a safety hazard because I will lost my clutch and cant' shift fears in the middle of intersections. This pedal has been replaced 5times and now needs to be replaced for the 6th times and it has damaged my clutch, my mechanic said do to the stress from the bad pedal the forced shift on my clutch have cause it to "slip" and now I need to purchase and have installed a brand new clutch that Nissan will not warranty either. This is a known issue with the 2005 and 2006 ser models and Nissan will not do a recall or fix the problems that come with it. My mechanic has told me that it is bad engineering and the issue will continue to happen so I have a spare pedal with him at all times.

The clutch pedal will sink to the floor during driving. Sometimes the clutch pedal will sink so low that it lays on the floor. When this happens I am unable to switch gears at all. I will have to pull the car to the side of the road and wait for about 10-15 minutes. The problem occurs at random times and doesn't seem to be associated with any particular event during driving. It occurs during different times of day, different weather types and at different traveling speeds. The issue has been ongoing for about 3-4 years on my car. It was first reported to the dealership while the car was still under full warranty with about 15,000 miles on the car. The dealership claims they have been unable to re-create the problem and have not replaced any parts. The last visit I took it in the technician topped off the clutch fluid, but this did nothing to resolve the problem. I have spoken to other Nissan Altima owners with manual transmissions and many are experiencing the same problem with no resolution.

Dear sir, I purchased a 2005 Nissan Altima ser with a 6 spd. Manual transmission approximately 14 months ago used with 33,000 mile and factory drivetrain warranty until 60,000 miles. My car currently has 59,000 miles. About two weeks ago, I brought my car to ira Nissan in woburn MA for a re-occurring clutch issue ; clutch pedal sinks to the floor making the car undrivable and grinding in the transmission shifting into third gear. Under warranty, Nissan replaced the transmission and clutch assembly. Last Monday, a week after getting my car back, the clutch is once again sinking to the floor just as before, and the Nissan dealer is saying because the can't replicate the problem, there is nothing more they can do, leaving me with a car that is unreliable and unsafe.the clutch fails intermittently and usually returns within an hour or so, making the car difficult at best to drive in traffic and making it hard to replicate on cue. The clutch appears to fail after an hour or so of driving or after it gets warm, with no warning. The dealer drove it for 7 mile and says it can't duplicate the issue.. Nissan customer service says they know nothing of the issue even though the internet lists over 60 incidents of clutch pedal sinks to floor on 02-06 Nissan with standard transmission, especially 05-06 Nissan ser"S.- but they have never heard of it" my case number with Nissan is 6600267. I use my car primarily for commuting gloucester to woburn and back and I typically don't have an issue, but it has happened 6 or seven time now and I know for a fact this wasn't mentioned in the sales brochure for this model Nissan. This is problemdangerous, as you can imagine being stuck in traffic and not being able to move. And not knowing when you can rely on your car, and when you can't" please assist me in making Nissan do the right thing and simply fix the car- they replaced the transmission, replaced the clutch and a week later, still under factory warranty won' T do it right.

Altima 6-cyl

  • Manual transmission
  • 36,100 miles
Car: 2005 Nissan Altima SE-R 6 speed manual transmission 3.5L V6. Problem: Clutch pedal fell to floor during normal use. This is the second time that this has happened to me. I had the first incident investigated by the dealership with no results. I have reported that incident to NHTSA separately. I had been using my car for a 1500 mile family trip. I was nearly halfway through my 12 hour one day return trip. I got hung up in stopped traffic in NY for about one hour fifteen minutes. We pulled off the highway to a rest stop and had dinner for about 30 minutes. I returned to the car, spent another five minutes in traffic and was moving along at highway speeds again. The car was loaded with 2 adults and 3 children and about 125 pounds of vacation stuff. Upon approaching a toll booth on the NY "expressway" I depressed the clutch to begin downshifting and decelerating from roughly 60 mph. The clutch pedal fell to the floor. Since this had happened before I was not caught completely by surprise. I put the transmission in neutral and began pumping the clutch as the car coasted in towards the toll booth. I was able to pump the clutch because it did have some small degree of return, but it did not reach the height of the typical pickup point which I estimate to be 6-8 inches off the floorboard. Pumping the pedal had no effect. I placed my foot under the pedal and lifted it all the way up. Pressing again had the same result. Very little friction. On the other side of the toll was dead stopped traffic. There was enough friction in the pedal to engage the clutch plates and to shift between gears. The traffic speed increased and after a few hundred yards the clutch recuperated on its own. I always double declutch and have never had to replace clutch plates in my cars.

Altima 6-cyl

  • 32,960 miles
Car: 2005 Nissan Altima SE-R w/ 6 speed manual transmission and 3.5L V6. The problem is that my clutch pedal bottoms out to the floor board. This has been reported over and over in the Nissan forum. Unfortunately, only a few people have reported to NHTSA. I used my car on a Sunday morning for a short run to the grocery store (approximately 8 miles round trip). I left the car in the direct sunlight on my blacktop driveway all day (about 85 degree F). In the late afternoon I started my car to put it in the garage. Before I turned the ignition I depressed the clutch and immediately noticed that there was no pickup point. The pedal was easily depressed to the floorboard and the typical resistance in the pedal throw was nonexistent. The car was already in gear and when I let the clutch out there was barely enough resistance to engage the clutch plates and pull the car into the garage. The pickup point was just a couple of inches off the floorboard, whereas the usual pickup point is anywhere from 6-8 inches. I left the car in the garage and made an appointment on Monday. When I started my car on Tuesday to bring it in to the dealership, there was no issue at all. I paid my $46.50 to get this on record with the dealer. They of course could not reproduce the error (as with nearly every other person that has had this problem) and saw no clear defects under the hood. I have the complete paperwork from the dealership if the NHTSA ODI investigator would like to contact me for additional information. For a history of the many incidents please see this page:
