Problems with 2006 Nissan Altima POWER TRAIN

Discovered antifreeze to be milky white in the reservoir and radiator it's self. will need to replace radiator and flush transmission fluid.

Vehicle was being drove down major highway when all of the sudden it loses all power, get off highway on edge put it in park, turn key completely off and try to restart car fails to start check engine light comes on and stays. get code pulled shows crankshaft position sensor a. get the crankshaft position sensor replaced and code cleared. head home with car, does same exact thing that happened while on the highway in town. have had everything else looked at and no one knows what to do to fix the problem. car acts as if it's hard to start ever since this happened. definitely won't be taking it out of town until something is done. car will sit and crank and crank then eventually decides to start. starter isn't issue it was previously replaced not even 2 months ago due to it going out.

Newly purchased used car....a slight hesitation and then sudden surge type feel under light acceleration at low speeds.

Jerking transmission.transmission jerks randomly when accelerating. occurs in city driving. this is continuous event.

Was leaving store and when pulled out onto road, i was involved in a crash! left the scene and then was taken by private vehicle to local emergency room and from there, airlifted with brain injury! was almost across the road and vehicle stalled and wouldn't accelerate and stalled and caused a horrible accident. the vehicle that hit me got me in passenger rear as he was traveling up highway and threw me and went air borne and knocked a telephone pole in half and done damage to front as well. air bags didn't deflate at all. i am making attempt to make nissan aware and opportunity to make right. i have researched what could cause this and recalls are effective while i'm going to state unknown to cause, as there are several reasons on forum as to what could cause this. takata recall for air bags but unknown on other. ...updated 07/11/17 *bf *js

Takata recall automatic transmission: while driving, it shutters when shifting from 1st to 2nd gear (aprox 20 mph). sounds and feels awful! parked it, and haven't driven it since.

Crankshaft sensor is bad causing the car to stall at any time - even at high speeds. it has happened while driving slowly through a neighborhood as well as on an interstate causing the car to be difficult to steer to get off the road. this is very dangerous! check engine light came and computer says that its the crankshaft/camshaft sensor that needs replacing.

Just like with other nissan recalls. my can shaft position sensor is bad and is causing my car to die/quit in the middle of traffic while driving it

Purchased this car used from a dealership 3 weeks ago. within 1 week the car stalled while driving. started it back up with no problems. took car on a 750 mi. road trip and while driving 75mph on cruise control the car bucked. after reaching our destination and turning the car off we had trouble restarting it. when it finally started the service engine soon light came on. took it to a mechanic and codes came up for the cam and crank shaft sensors. replaced these sensors and cleared codes. drove car away and within 5miles the check engine light came on again and again excessive cranking when trying to start the car. brought it back to mechanic and the brand new cam sensor that was replaced less than 24hrs before tested out bad. replaced sensor again and cleared code and code came up for high speed input sensor along with the same codes for cam shaft and crank shaft sensors. again trouble starting vehicle. drove car 750mi. back home without turning the car off for fear of not being able to start again. dealing with a nissan dealership to try and get this fixed. this issue was under recall before. the bucking of the car while driving at 75mph was terrifying and seriously dangerous!

This vehicle has given me a lot of problems from steering to brakes took the boots transmission. it was hard shifting going through an intersection all the sudden it popped and the transmission gave out

When driving the car the gear gets stuck and you have to allow it time to catch up with the accelerator so you can take off if your sitting at a light or trying to accelerate speed when driving. it also jerks at times when driving on the highway.

My 2006 nissan altima has started to have a transmission slip. it jerks very hard when accelerating. very unsafe to drive.

I just bought the car used. felt vibration in engine was told it was a motor mount. checked on line because car shifting hard 3 days after purchase to find out it has transmission issues that cause motor mount wear and tear and replacement and may need transmission replaced. nissan needs to fix this issue

Consuming or burning a lot of oil.had to add about a quart of oil every 300 miles. it takes longer to shift and does not have power going uphill. hard 1-2 shift.

Vehicle is violently shifting into second gear. transmission is starting to fail. vehicle has only 91,000 miles.

I was driving on cruise control at 70 mph. the car bucked, but kept going. i exited the highway a few miles later and came to a complete stop. with cruise control now off, i attempted to proceed as normal, and the car lagged in power. i almost got broad sided as the car didn't go as normal. i pulled out with a right on red. the car was stuck in 5th gear.

Transmission problems rpm going out and them down and don't gear well

While stopped at a red light my car engine shut off. after a while it started again, but the transmission wouldn't shift to lower gears and jerked hard in reverse, and service engine light came on. when i took it to the shop the cam sensor had to be replaced. after doing research, i found this was an issue and a recall on some models but not mine. why only one model was recalled? *tr

While driving down the road entering highway i went to shift my 06 altima 5 speed into 5th gear when i pressed the clutch pedal there was no pressure and transmission would not go into 5th gear. i let up on the pedal and in a few seconds the pedal had pressure again. enter highway and drove for about 25 miles and exited highway. the same thing happened again no pressure in the pedal then pressure. i was able to return home but the problem is still happening. i have read some forums on this issue and it seams that many people are having the same problem. some people say they replaced the master cylinder and slave cylinder and this did not fix the problem. other people recommend using a dot 5 brake fluid with a higher boiling point.not sure what direction to head in. as a life long mechanic for dealerships it appears to me that the fluid is boiling out and causing air pockets in the hydraulic system, then bleeding it self out. it was only 77 degrees this day so extreme temps are not always the problem.... *tr

Tl* the contact owns a 2006 nissan altima. the contact stated that while driving approximately 45 mph, the clutch malfunctioned causing the driver to lose control and crash into a median guardrail. there were no injuries and a police report was filed. when depressing the clutch, the pedal would not release and would remain stuck. the vehicle was taken to the dealer who replaced the clutch, but the failure persisted. the manufacturer was notified of the failure. the failure mileage was 52,000.

Tl* the contact owns a 2006 nissan altima. the contact stated while driving approximately 55 mph, the transmission down shifted violently with extreme hesitation. the failure recurred whenever the vehicle was being driven. the vehicle was taken to an authorized dealer, who informed that the transmission would need to be rebuilt. the vehicle had not been repaired. the manufacturer was not notified of the problem. the approximate failure mileage was 106,000. the vin was unavailable.

Driving on dry road at speed engine suddenly stopped. pulled over to side and before car fully stopped put into neutral and engine restarted. then placed back in drive and continued 50 miles with no further problem that day. on 12/15 while on interstate the engine stopped again with much more danger as traffic was coming up on our rear. managed to get into breakdown lane and while going 15/20 mph placed the transmission into neutral and engine restarted and proceeded 50 miles to home. brought into nissan dealer on 12/18 and they claimed they checked it out and could find no problems. nissan customer service opened a case #[xxx] but has not returned calls after the nissan dealer diagnostics. the car is a danger to ourselves and others but it is our only vehicle. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

My altima's transmission began slipping out of gear while taking my children to school. it started slipping bad enough where i felt the vehicle was not safe to drive and needed to be towed. as i pulled off a main road onto a side street, the transmission slipped out of gear while turning and a vehicle nearly struck me on the passenger side. luckily the transmission went into gear at the last possible second so i could escape the accident. after doing research this is apparently a common problem with the v6 altima transmission.

Car is getting stuck in 5th gear which causes stall outs while driving and no acceleration-only 102,000 miles-hesitates, jerks and stalls out randomly. *tr

Tl* the contact owns a 2006 nissan altima. the contact stated that while driving at 70 mph, the vehicle decelerated to 30 mph without warning. the check engine light illuminated and the contact noticed load roaring noises. the contact maneuvered to the emergency lane and the vehicle stalled. the contact discovered oil leaking from the front of the engine. the vehicle was towed to a mechanic who diagnosed that the catalytic converter, engine, radiator, transmission, and engine cooling system failed. the vehicle was repaired, but the failure persisted. the manufacturer was not made aware of the failure. the approximate failure mileage was 103,000. . . .updated 07/21/15 *bf updated 10/19/217*cn

I own a 2006 nissan altima ser. i have had the motor replaced and the entire clutch kit and slave cylinder replaced. after having the clutch parts replaced the pedal stuck to the floor a small handful of times. now, it is nearly a daily occurrence and it is consistently lasting longer and longer each time. it still allows for sporadic shifting in non specific gears while the pedal is on the floor. i can pick up the pedal with my foot and put it back in place but when it apply any pressure it falls back to the floor and stays there until i pick it back up with my foot. this issue has nearly caused to be in several accidents, all of which i narrowly avoided by quickly maneuvering my vehicle off the road. *tr

This is the second time within a year and a half that my clutch system has went completely out while driving. while driving i could not get the clutch pedal to engage the clutch. it was becoming increasingly more difficult to get the clutch to shift into gear even with the pedal pushed all the way to the floor. this is the very same situation that happened the first time the clutch system went out at about 60,000 miles. the mechanic contacted nissan and they said they knew that there was an known issue with the nissan altima ser 2006 and its clutch system. the standard dot 3 fluid that is used was becoming to hot and breaking down its compressibility not allowing the clutch to shift. this time around when the mechanic called nissan yet again, nissan said that there is an issue with the clutch systems used in the altima ser 2006 and that they have been replacing a lot and seeing that they are only getting between 35,000 - 40,000 miles when the life span of the clutches should be longer!!! this is not a cheap fix and is becoming increasingly annoying. this is an unsafe car for anyone to have and luckily neither incidents caused any accidents. nissan knows there is an issue with this model of car but yet nothing is being recalled on these clutch systems!!!! *tr

Traveling at 15 miles per hour and started to stop at stop sign, vehicle went dead and i could no stop in time and went through the stop sign. hard to steer also. luckily no other vehicle was approaching or an accident could have occurred. service engine soon light came on afterwards and gave code p0335. *tr

Driving on i-4 transmission heard a "pop" sound, car had a hard time going from a stopped position to moving. added transmission fluid, worked fine until the next day when the same thing happened. car once accelerated seemed to accelerate faster without me pushing on the accelerator. purchased car 2 yrs ago and noticed a random hard shift either when accelerating or decelerating, no major problems to take it anywhere. had transmission fluid changed and flushed seemed to help problem until now. i have 3 kids and with the problems of this nature could have a serious impact on us financially not to mention if something were to happen while driving. our safety as well as others could be at jeopardy. *tr

I have a 2006 nissan altima, that is constantly 5-7 mph off. i am getting concerned because this is a hazard as i have been asked by the local city police for me to pick up my speed a little as i am restraining the flow of traffic by driving at or below what i believe is the speed limit. also, i am really concerned since the factory tells you to use a certain size of tire, with me using their recommendation, this will cause the wheels to spin faster than what i am actually really going, thus saying i am traveling farther (mileage) than what i truly am. this, i believe is effecting my gas mileage as my tires are having to spin faster than what is needed and thus causing me to use more fuel. please help me consider my options or do you know if there is a recall on the speed sensor, drive/powertrain, wheels, etc. someone who drives 10 mph on the interstate is a hazard, i believe. i am having all kinds of vehicles and semi-trucks pass me on the interstate and i feel the safety of my family is at risk in driving this vehicle. (my current mileage (supposedly is: 43500 miles) i may have traveled less than that. can you help me get this issue resolved? here is a cbs story on the issue: http://www.cbsnews.com/stories/2007/03/13/earlyshow/main2562144.shtml please help, my families safety could be at risk as well as other passengers who own or are on the road around these cars.

Clutch falls to the floor, leaving you with the inability to disengage the transmission from the engine, causing you to fly to the shoulder as fast as possible, stepping on the brakes hard enough to shut off the engine. there are thousands of nissan forums describing this problem. the car has 80,000 miles on it now, and it happened again tonight, causing my wife to run the car off of the road when she began to panic because she couldn't stop the car at a busy intersection. the clutch will resume normal function in a matter of minutes, and wont have a problem for months. very, very dangerous! *tr

Several 2005 and 2006 nissan altimas se-rs (including mine) have had issues with the clutch pedal getting stuck on the floor unable to come back up and not being able to change gears. dealerships accross the country have deny the issue and deny repairs. this is a safety issue and an accident can happend due to this. to me, is been happening since i purchase the car at 37,000 miles and it keeps happening now at 86,000 miles...this is happening to several others as well and a website has been created with everyone's concerns. please recall!!! *tr

Attempted to shift and clutch pedal sank to floor and would not return, clutch did not disengage. made it very difficult to get car out of gear, and impossible to reengage gear. luckily was able to coast to a stop without accident. dealer reported failed clutch line / master cylinder led to loss of fluid & inability to disengage clutch. *tr

Nissan altima 2006 manual transmission: clutch losses pressure. i have taken car in to nissan for issue. vehicle bought in aug 2006. approximately 2 years later issue began. clutch drops down while car in motion. manually move clutch back up with foot. when first taken into nissan (windward nissan, honolulu hi) was told that there was nothing wrong. clutch continued with issue very intermittenly. upon arrival to san diego ca, i decided to take to mossy nissan (national city). i was told that i needed a new clutch. i was reffered to nissan 1 for assistance. nissan covered the replacement of the clutch. it has then been about a year and a half and issue persists. now clutch drops and i have to pull over, wait a few minutes and see if clutch comes back up. cannot put vehicle in gear while clutch is down. i googled "clutch issues with nissan vehicles" and there was a link to your website. *tr

Tl* the contact owns a 2006 nissan altima. the contact stated while driving she continued to hear a loud noise coming from the back of the vehicle. she also mentioned that every time she had to shift gears they would lock and in order to continue driving she had to engage the shift release button. the vehicle was taken to a local mechanic who diagnosed that the gear shift needed to be replaced. the manufacturer was not made aware of the failure. the vehicle was not repaired. the failure mileage was 84,000 and the current mileage was 86,000.

I have had my engine replaced as a recall but windsor nissan has no record when i asked for the report. i went in to the dealer on 12/16/10 at 5:30 pm because i was having problems as the gear shift was getting stuck in park and couldn't move at all. i read the book which says to push the shift lock release button which will let me move the gear shift temporarily. i then contacted the dealer who in turn told me to bring the car in to check it out. they wanted to charge me $110 just to see it until i disputed that. afterwards, he told me that the shift lock control unit needs to be replaced, he couldn't explain to me why the car just up and started to act up or what leads to that. i have an older model nissan altima and it runs better than the 2006. i have had more problems with the new car than i had with the old one. i have also had to replace the back brake lights 6 times within the year because it continues to blow out as well as the over head light on the inside of the car. the only thing that confuses me is the gear shift, now i'm subject to pay $300 for this part being replaced because it isn't covered in the warranty and no one could tell me exactly what causes this problem. i need to know what is causing the problem and what can be done to keep this from happening in the future. i have contacted other mechanics who seem to feel that this shouldn't have happened especially because the car is only 4 1/2 years old. *tr

On cruise control, traveling in a 50 mph going 45 suddenly the transmisson went into a high pitch the engine went to nearly 6000 rpm, reversed the cruise and it restored, the gears on the auto transmission has been messed up ever since.

I purchased my nissan altima se-r in june of 2007. during that summer the clutch would stick on few occasions and i wouldn't be able to change gears. on one occasion i had to pull off the freeway and pump the clutch petal multiple times until it became free and i was able to change gears successfully. i took the vehicle to the nissan dealership to which they told me to bring it in when the problem was actually occurring, which was virtually impossible since it was sporadic. i have noticed that during winter on occasion the clutch and brakes would need to be pumped before driving otherwise the clutch would stick and the brakes just wouldn't work. this morning i got in my nissan which had been parking in the garage all night, and the clutch petal was sunk to the floor. i was able to turn the car on, but couldn't switch gears. i tried pulling up on the clutch petal with my foot and nothing. it took multiple times of trying to pick it up with my foot and trying to un-stick it by pressing down hard on it before it finally came up and i was able to put it in reverse to drive. *tr

2006 certified used nissan altima will not come in and out of "park", or into "reverse" while trying to go into "park". shifter and related parts have been replaced with no success in september 2010. problem has been ongoing since february 2009. car has been to dealers multiple times to diagnose problem with no success. shifter and electronic module replaced later september 2010. problem came back within 48 hours of getting car from dealership. owned car for only 8 months before problem arose. *tr

2006 nissan altima ser. when driving the clutch sinks. several pumps will get it back in order. also at times on a cold start it doesn't feel like the clutch disengages completely. *tr

I have been have trouble with my 2006 altima se-r since buying it at 52k miles. it's like everyone else; the clutch gets real floppy and looses pressure until it sinks to the floor and wont return. this has happened to me about 30 or 40 times since buying the car in october 2009, but i can't replicate for the dealer. they also say that they have never heard of this before, and nobody has ever complained about it to them - apparently they are lying. this afternoon, i was driving my son home from daycare, and the clutch did this very thing, but for the first time, i could not get the car out of gear and i was in bumper to bumper traffic. i almost hit the guy in front of me. when i finally yanked it out of gear, i couldn't put it back into gear because the clutch was stuck to the floor. i sat on the side of the road for an hour with my 14 month old son in 99 degree heat waiting for the clutch to "repair itself". this is bogus and nissan needs to own up to their responsibility of fixing these cars before someone dies. *tr

After completing acceleration after a period of sitting in traffic, the clutch pedal fell to the floor without the aid of the driver. the clutch pedal lost all resistance and the driver was unable to get the vehicle out of gear and into neutral or another gear. driver had to maneuver the vehicle off of the freeway and onto the shoulder and coast for several hundred yards with the vehicle stuck in gear for the clutch pedal to regain pressure so that the vehicle could be placed into neutral. since the initial incident, which occurred only weeks after the vehicle was purchased from a nissan dealer, the sunken clutch pedal has become a regular occurrence, nearly daily. *tr

I have a 2006 nissan altima se-r. the clutch repeatedly looses pressure when the ambient temperature is hot combined with a heavy traffic situation. i have brought the car to the dealership several times and they say they have replaced the cylinder, but the problem persists. i did a little online investigating and it appears as though i am not the only person that owns an altima that is plagued by the safety issue. it almost is impossible to shift. *tr

Regular driving. i went to park car and could not take out of gear only able to put the car in neutral and leave key in ignition . the car rolled into and was stopped by curbing, thankfully, before rolling into a busy road. the shift lock solenoid on nissan altima locked up. the shift lock solenoid and shift lock control module were replaced and old parts kept by dealer. *tr

Right engine mount broken at 66k miles. *tr

On my 2006 nissan altima with the manual transmission, it has a tendency to just lose pressure on the clutch pedal as i am driving making it hard or sometimes very near impossible to shift in and out of gears.......has happened to me on busy roads causing a very scary situation. *tr

1-2 times a week,i have to repeatedly push hard on the brake to get the car out of park. i am not parking on any kind of incline. this has gone on for several months. now twice in the last 2 months, i go to get ready to park the car,and my gearshift will go to neutral but will not go into reverse or park. i tried costing the car a bit,tried driving it forward a bit,i even shut the car off in neutral, nothing worked. finally,while in neutral,i revved the engine a little bit and gearshift smoothly started working again. *tr

We purchased a used 2006 nissan altima, with in a month of purchasing this vehicle we were unable to get the car out of park or into park. we thought it might have something to do with the winter weather, because it was periodically happening. it is now summer and it happens every time we start the car. it even happens when we have been driving the car and pull in to a parking spot , we are unable to get the car into park. we have been overriding the lock mechanism by inserting a metal tool into it, but it is quite inconvenient every time we drive the car to have to do this! *tr

The vehicle is slow in changing gears. *tr

For no apparent reason the clutch pedal will lose all resistance and lay on the floor leaving the vehicle inoperable and stranded on the side of the road. this issue has happened multiple times, as early as 44k miles and as recent as last thursday, march 24, 2011 with 68k miles. pumping the clutch pedal for an extended period of time did restore enough hydraulic pressure to operate the clutch and within 2 miles of "in town" driving the clutch problem completely resolved as if it never happened. there are multiple complaints of this issue on the forums. fort pierce nissan official answer was " nothing". they wouldn't acknowledge it. i'm sure with all the complaints from altima se-r owners nissan is fully aware of the issue, yet they won't step up to the plate and make it right for their customers. i've been a loyal nissan customer since 1988 but without proper resolution, this will end that streak.
