Altima 4

  • Automatic transmission
  • 124,600 miles


Called Nissan local and they said even though my Altima is the make model and year of recall my VIN number is not included in the recall. I have paid out over $1000 + dollars to figure out what is wrong with it to find out there is a recall but my car is not apart of it. I will never buy another Nissan if my life depended on it. I priced out to fix it and it would be over 500.00 more dollars! It has died on me while I was driving it and wouldn't start even after I only parked it for max 10 minutes. I called Nissan Canada and they tell me that's too bad and there is nothing they can do. I paid the money for the car and there is a recall then fix the problem. I have a small child what if my car dies again and my child and I are in the car in the middle of no where. I don't have the money to get a newer car and I don't have the money to fix this problem now! Nissan is the WORST company ever and the WORST for customer service. THE WORST EVER!!! For all you people out there with Nissan autos good luck!!!!

l believe that Nissan should replace the bad parts and do the replacement of the crank shaft sensor and the cam sensor for this, as this the root of the problem. But the company has decided to take the easy way out, only to do the resetting of the computer problem. My car has stopped on me while driving 3 time and this is a dangerous situation. l will get my car fixed for these issues but l will also see if l can get some legal guidance on what are my other options to hold Nissan accountable for issues they know are a problem, as well as the one's they have refused to address.

l personally will not do business again with Nissan and l will inform all of my family member not to purchase their product again. Thanks for your time and hearing my concerns. This problem as well as other problems they are aware of on their older cars that will cause harm to the consumers who have purchase products from Nissan. l will only buy American made cars from now own.

Thanks for your time

Altima 25L

  • Automatic transmission
  • 50,142 miles


My 2005 Altima 2.5L car with only a little over 50,000 miles is shutting down without warning while driving. It will not start on some occasions and others will start right back up. Usually it will restart after a cool down period of 10-30 minutes. I took the car to a Nissan dealership since this problem is part of a recall and they wanted to charge over $300 to replace the Crank position sensor and the Cam sensor. My son did the labor and saved me over $200. After replacing the two sensors, I brought it to the dealership and they charged me $120 to reprogram the ECM. Now after only a year and about 1,500 additional miles on the car, the problem has returned. I will replace both sensors again but the dealership told me today that it is not necessary to reprogram the ECM again after the sensors are replaced.

I have no comfort of the safety of my vehicle. Stalling while you are in traffic is the scariest thing possible especially for a 60+ year old driving alone. I called the government department that issues the recalls on vehicles and posed the question why Nissan is not responsible for the replacement of these sensors or at least the cost of reprogramming of the ECM and received no satisfaction with their answer. They make us aware of this problem but Nissan is not held accountable for the problem nor the solution.

Altima SE V6

  • Automatic transmission
  • 109,665 miles

The car just shut down while driving, I managed to get it back on but had to keep the engine revved to get home. It has not done it since so I'm not sure what to do?

Update from Aug 1, 2015: Car has another hidden code (PO 726) and it is still shutting off. The code indicates that there is a problem with the throttle body control valve which new is about $300.00. This particular model 2005 3.5 Altima seems to be the most difficult to diagnose as most of the failures have similar symptoms but, do not always throw a code. I have to date replaced the PVC valve,air fuel mixture valve, mass air flow valve, fuel injectors,cam shaft & crank shaft sensor, plugs to mention a few. This has been done in the past four weeks and, the car still does not run. It does however look good.Update from Aug 1, 2015: I forgot to mention that I replaced the fuel pump too! I will keep ya posted if it's the throttle body control valve.

Update from Sep 10, 2016: After replacing some $2,000.00 in engine parts it found to be the mass air flow sensor. I had already replaced that but, unfortunately bought a bad one on Ebay. It was thought to be a good price but, I paid for it in the end. Even Nissan stealership couldn't figure it out. Whoever buys it now will have a new car.

My Nissan Altima 2005 2.5 SL engine automatically switch off while I stop at traffic signal in neutral gear or move slowly in parking lots. Its been month I purchased this car and it happen 5 times. After the engine switch off all the indicators in dashboard light up like battery, engine and then If move the gear into 'P' parking mode and turn the key fully it switch on the engine. I showed to different mechanics and tested two computer with computer to detect the code. But it don't show any trouble code and mechanic says we are not able to detect the problem.

I don't know what to do next.

Altima 2.5L V4

  • Automatic transmission
  • 47,000 miles

Twice my car engine has shut down without warning at an intersection in downtown DC - once when I was driving to a dealership to drop it off - which is an entirely scary and dangerous situation to be in at rush hour.

I did research and found a recall notice on my car that could easily explain the situation: the crankshaft sensor overheats causing an interruption to the electronic control module, which causes the engine to stop running without warning while the vehicle is driven at low speed.

As easy as it sounds to get this corrected - there's a national recall after all - I'm getting absolutely nowhere and paying money to do so. After my car shut down the check engine light came on. I went to a dealer to perform the recall maintenance, but they say that because the check engine light is on, they can't adjust the ECM (like the recall notice says) and that they have to run a diagnostic to tell me what the problem is. We argue because clearly the problem is the crankshaft sensor. I pay $126 for a diagnostic test and guess what? The problem is the crankshaft sensor! They first quote me $540 to fix the crankshaft and cam sensors. When I asked what's wrong with the cam sensors, they say they just usually change them when they change the crankshaft sensor. Um, so does the dentist also drill holes in your molars when he's filling other cavities because they usually do that at one time? So then they quote me $395 to just replace the crankshaft sensors. Once they do that, the light will go off and they can do my "free" update to the ECM for the recall.

So next up, I called Nissan corporate, who suggested I take my car to another dealer for a second opinion. They've also opened a case for my complaint. My 2nd appointment is tomorrow (p.s. who has time to run around various dealers and go without a car?). Finger's crossed. Will update once I have that appointment.

Altima 2.5L V4

  • Automatic transmission
  • 65,000 miles

Today - in morning rush hour - at an intersection in the center of DC all of the lights on my dashboard flashed and my 2005 Altima died. Did I mention being IN AN INTERSECTION? I was seriously panicked about being hit by an oncoming vehicle.

While being screamed and honked at by drivers behind me, I alternated pumping the gas pedal and trying to crank and was eventually able to get the engine to catch for a 2 block drive to a parking garage. Heaven knows what awaits me when I go back this evening as I'm sure it will die on the attendants as well.

In researching this problem, I did find that there was a recall on the 2005 Nissan Altima (those with 2.5L engines) related to the crankshaft position sensor and the car's electronic control module (ECM) in late 2007, which I didn't previously know about. The "consequence" listed for the malfunction is that "the engine will stop running without warning while the vehicle is driven at a low speed." Sounds about right.

Made an appointment at a Nissan dealer tomorrow to have my ECM reset. Will report back - hopefully with happy news that (a) I was not in a major traffic accident due to my car dying while attempting to get to the dealership, (b) the recall correction remedies the problem and (c) that they do not charge me for any additional or unwarranted services. It seems a lot to ask at this point.

Altima S 2.5L

  • Automatic transmission
  • 82,314 miles

All this happened within 6 days after purchasing my 05 Nissan Altima. 1st As I pulled off the lot he car was completly empty on gas so Nissan gave me a voucher to fill my tank up with gas, so when I go to pop open the gas cap from the switch inside the car it did not work, I tried several things put it wouldnt open, so I just slid my credit in between the latch to open to fill up, but during this I had called my salesman telling him what happened he didnt know what to do since all the mechanics where gone, then afterwards I told I had opened it already. He just told me to bring it back and they'll fix it free of charge.

2nd On my way home from the gas station the check engine light came on, I couldnt call Nissan till the next day due to they where closed.

3rd When I was driving home from the dealer and gas station, I was driving through winding roads I notice my driver seat back rest was swaying slighty side to side. All this happened Saturday evening after leaving the dealers lot.

4th My new/used was dirty because it wasnt detailed so the next day I had gone to the car wash to wash my new (USED) car. As I was spraying the soap on, the black trim on the ceiling had pop off while I was spraying the car. I just pop it back on as best as I could for the time being. The very next day, Sunday

5th I noticed the enging vibrating when the air conditioning unit was on, alot more than normal. Sunday also I had called Nissan that day tell to speak to the saleman and he was off for the next to days, so had spoken to the manager regarding this issues and he just said didnt you notice any of this when you test drove the vehicle, first I said I didnt test the gas cap since I was testing driving then with the seat it doesnt sway in the city when your driving straight with no curves in the road to notice, with the trim he really didnt understand so he just asked me to bring the car back and they'll fix my these problems. Sunday afternoon

On Wednesday my saleman had called and said he had found another bank giving me a better deal with $100 less payments a month and 4 to 5000 off the price if I can come up with an additional $300 on top of the $500 I gave them along with the my trade in, and they still fix my problems.

6th Still noticing the vibration from the air conditioning unit, as I was driving through road construction the car had shut off briefly then kicked back on. I immediatly called Nissan and spoke to my sales man and told him what happened an he had made an appointment for the next day. Then later that day as I was turning on to the freeway the car shut off again this time for 5 minutes. I called my salesman again and told him I was sitting on the side of the road with a broke down car. He had placed me on hold to get me some help, I wasnt on hold very long and I kept on trying to start the car and it finally started back up. I told him I was bringing the car back and I needed a car immediatly because I was working still ( I work in sales so I travel alot in my personal vehicle), he said no problem. The mechanics new what the problem was, and everyone garunteed me everything will be fixed and the salesman still trying to get me to sign the new loan agreement and telling me the warrenty on the car had gone up to 150,000 miles, I was irritated with everything I had just left with the rental car to finish my job. This happened on Friday exactly 6 days later.

7 days I go back and speak to Nissan regarding my loan and vehicle wanting me to keep this car. Bought car July 2, 2011 taken back in for repairs on July 8, 2011 suppose to finish papers on July 9, 2011?

The car was shut off when I was driving and I was so scared. I took it to dealer to fix it. The computer diagnostic report says it was a cam sensor and crank sensor problem. They also said the ECM was not reprogrammed and they reprogrammed it for free. However, I have to pay for the replacement of the two sensors and the labor along with it, which is $450. I told them the engine was shaking when I drove on highway and from the 1st shift to 2nd shift. They did nothing about it. I found the engine shaking is still on... I have no idea what happens to it.

My 2005 Altima 2.5S shuts off in the middle of traffic with no warning. The check engine lights has been on... I replaced the battery (because it needed one of those too), Advance auto ran a simple diagnostic test code for the crank sensor. Its very scary after seeing so many complaints I do'nt understand why Nissan won't do a recall on this car. Does anyone have any information about where to complain directly to Nissan?

car shuts down while driving

There I was in my nissan when suddenly the engine shut down. I turned it back on and it worked fine. This was in Nov 2010. In late December , this happened again. On Jan 2, it stalled again but this time the (check engine) light came on. It stayed on. Took it to an expert car mechanic , who connected a code generator- he said the crank shaft sensors needed replacement. Bought them for $100. Inspection cost $30. Labour cost $35. So far, the check engine light is off and the car hasn't stalled.

My 17-year-old daughter was driving home from a swim meet and her car died without warning. Now the car shuts itself off 4 or 5 times a day. We replaced the crankshaft sensor and it didn't fix the problem. Now she is unable to drive her vehicle because the last time it shut off she was almost rear-ended by a truck. We bought a Nissan because we thought they were reliable vehicles, but after searching the internet we found out that this is pretty common for Nissan. One person said they had to have the engine computer reset.

Altima SL 2.5L 4 cyl

  • Automatic transmission
  • 59,000 miles

My 2005 Nissan Altima 2.5 SL quit running while driving. Firestone read the code as Crankshaft Position Sensor, and even over the phone Advantage Nissan service dept said it sounded like the Crankshaft Position Sensor. Took it to Advantage Nissan, and they did nothing as they said the code was cleared and they couldn't recreate the problem. At this time I was unaware that there was a recall for this issue directly, and Advantage Nissan service did not even tell me. Total waste of my day with the car in their shop.

Update from Oct 14, 2010: Please make sure you read the wonderful updalte from October 9, 2010 as the Nissan Corporation and Advantage Nissan helped me out WONDERFULLY. I cried with joy as they paid for almost everything.

Third time in the shop for this same problem for my 2005 Nissan Altima 2.5 SL within 2 months. Codes read Crankshaft Position Sensor and Cam Sensor. Advantage Nissan only replaced the Crankshaft Position Sensor...??? Very scarry and and a definite safety issue when your car quits running in highway traffic. Advantage Nissan still did not tell me that there was a recall on this very issue, and still had me pay my under warranty deductible of 55.00.

Altima SL 2.5L 4 cyl

  • Automatic transmission
  • 73,835 miles

My 2005 Nissan Altima 2.5 SL quit driving in high freeway traffic. Had to tow it to the Advantage Nissan Service Dept and the code was a Crankshaft Position Sensor ..again, they had replaced it on this car 1-26-2010 already. They also told me that it had an engine knocking noise that they felt was internal engine issues and now has metal in the engine/oil. It is 3,835 past it's warranty and I am now basically told "sorry charlie", I would have to pay for the new engine they say it needs. They want copies of all my maintainence records as they feel I must not have had the oil changed regularly enough. I have had maintained the car excellently...regularly...however, I have misplaced my zipper bag with all my maintainence records in it, and all I can find is four I got from Firestone and Wal-Mart service. I had my oil changed once right there at Advantage Nissan with one of their own coupons, and they don't even have that oil change in their computer (how convenient). I will have to have it towed back to my house and sit in my driveway until I can someday come up with money for a new engine.

Update from Oct 9, 2010: Just wanted everyone to know that after talking to the Nissan Corporation about my engine, Nissan paid for ALL THE PARTS it took for fixing my car engine, and my dealer Advantage Nissan paid two thirds of all the labor costs for me. I only paid $499.54 for the labor, and got a whole new engine and got me all working great and back on the road. Thank you Matt and Brad. 100 big thank you's.

The engine stops running without warning while the vehicle is driven at a low speed. Apparantly this is an ongonig issue., and the recall is for 654,793 vehicles in the US. However there is none in Canada. My vehicle is doing the same thing. This is extremely dangerous as you well imagine. Driving along the hwy, or even trying to pull out from a stop sign could cause an accident. If it is such a safety matter, how come our government does not force Nissan to fix the problem in Canada. And by the way how many accidents was caused by this situation, and how many were injured or killed.
