Car completely losing power while driving


Asked by Feb 03, 2015 at 11:54 AM about the 2012 Nissan Altima 2.5 S

Question type: Maintenance & Repair

While driving I lose all power. No warning lights, no check engine. Outside lights go off as well. Sometimes it turns itself back on quickly, others I have to restart the car. Was happening when slowing/coming to stop but now happening frequently and while driving. Replaced a sensor on the battery wire as that's the only code it threw, still doing it and now showing no codes. Car has been in the shop three times and Nissan cannot find the problem.

Check the fuel pressure?May be fuel pump,

I would try replacing the Crank Position Sensor. There are a lot of complaints with your model not starting. Check out this forum: altima/TEUIGP0N4PCM77QLD/p4

The car starts and restarts fine. It is shutting off while I am driving it.

your Altima should be still under warranty, go to the dealer it will be free

In regards to the last two responses: 1. It has been hooked up to a scanner, no codes come up. 2. It is at the dealer. They cannot find the problem and have had it a total of 15 days over the past month. Total of three different times being in their service department.

If every thing is going off, it could be losing ground somewhere.


Did you ever figure out the problem? My car shut off yesterday while driving. All lights went out and I lost all power. I have a 2011 Nissan Altima 2.5S

thank you!

220 Ford Explorer did the same thing....from another thread on this website under "loss of power while driving." I was able to find out that it was the throttle body assembly, after several trips to the dealership without an explanation as to what was wrong with it. Maybe it is the same issue with the Altima. I have not had any problems since I had it replaced. My car was less than 3 years old when it happened. It was built in 2011 as a 2012 model. It makes me wonder who is manufacturing these parts???

I have a 1999 mazda esmy car loses power


I have a 2012 Altima and it has done this twice over the last 2 weeks. Just talked to my dealer and they claim they have never heard of this happening.

Jeanne, your dealer is lying. The stall issue on the Altima is a known failure. I have read many posts and threads on this issue. I have not found any common fix. People have replaced all the sensors to having the car reprogrammed. Problem still persists. I would trade the car in. problems.php Or you can try the usual parts. The crank sensor, MAF sensor, and cam sensor. There was a recall for the '02 Altima for a faulty crank sensor. You can give the dealer your VIN # and see if your model has any recalls. If your check engine light is on, have the codes read. That should narrow down what part has failed. Typically the check engine light does not illuminate with this stall issue. I believe that there will be a class action lawsuit against Nissan for this issue. It is very common. Kind of like the newer Camrys and the oil consumption issue that Toyota has failed to recall.

Did anyone ever figure out what's causing this issue? I've started to have the same issue with my 2012 Altima and my research shows that this is a very common problem, but I called Nissan and they "have no knowledge of this issue". Yea right. I'm taking it to the dealership today but the check engine light isn't on and the battery/alternator are fine. Any suggestions?


I've never read about this problem with an Altima, BUT, for my ford explorer, it was the throttle body assembly....had it changed and has not happened since. The dealership also acted like they didn't know what was going on....complete cover up by Ford!!!!! They do know what causes the problem...they are covering the replacement on the Ford Edge, I believe, but since I don't have that model, I had to pay out of pocket....almost $600....just to find out that my son could have changed it for about $100....not happy with Ford right now.


I'll just sit back and wait for you to have your own reality show first. I wanna see how it works out for you. Maybe you and Honey Boo Boo can team up together and have a battle of wits. Should be priceless.............

I don't have a Nissan, but my Honda did the same thing for a while. Bogged down to the point that sometimes it would die at an idle. I ended up changing the plugs, plug wires, distrbutor cap and rotor, and cleaned the throttle. Ended up being the EGR valve. Literally put hundreds of dollars and 15+ hours into this car over the course of 5 weeks, and it was a $100 and 15 min fix. Just throwing that out there.

2013 altima lose power and battery and brake light come on. Replaced battery, cable and alternator still same problem

I have a 211 Nissan Altima and have been dealing with this problem for over 3 years. I have replaced battery and terminal, 3 dealer original MAF sensors with reprogramming, and the problem persist. They even suggested it was the CVT transmission-- supposedly a warranty cover common issue with Nissan. This is the reason they extended their transmission warranty 120k. However, I didn't believe because it was a 5k job that was not longer cover for my car. I know the issue is related to fuel. It comes soon after the car rides on gas tank that is less than 1/2. A fuel injector cleaner improves the problem. My theory is that the car pumps more gas that it can burn and it shocks. Kind like when you try to jump a stalledcar and you give too much gas. The engine does not burn the gas that build up in it. I am the problem is in the fuel system. This is a factory malfunction on the Altima. I have read thousands of posts on the same complaint. I am just waiting to settle some debts before so Ican buy another car, since this piece of crap is paid off already.

I have a 2011 Nissan Altima 2.5 the standard one. I had this issue for almost 3. I have replaced battery, terminals, 3 MAF sensor and reprogrammed the whole car 3x. I have done tons of fuel injector cleaning... then I was told it's my CVT transmission that needed to be replaced, but it was not longer conver on their extended 120k warranty. However, I didn't believe it because I noticed the problem happens after the car runs on a low gas tank-- like 1/4 to E. if I let this happens the issue returns. I believe there is an issue with the way the car burns the gas. The engine injects more gas than the car is able to burn and shocks. I am waiting it out for another year but a new car, but never a Nissan Altima.


Kizzy, was your car showing any error codes this whole time? Just curious if it was or not. There are many things that can cause your fuel system to inject too much or too little fuel. Judging by your observations, I would think it would be fuel pump related. My guess would be that for some reason, your fuel system is losing pressure as the tank becomes low on fuel. Did any mechanics test for fuel pressure fluctuations when the tank is low on fuel? Was the fuel pump replaced during any of your maintenance to fix the issue? Did anyone suggest a faulty fuel pressure regulator?

Reelin68, yes the car was always showing the air flow sensor. When we replaced it goes away for exactly 65 miles then the check engine light comes back with the same code. We changed the terminals at the MAF too. The traction lights come on and then it begins to act out again. When I tried to replace the fuel pump, I was told by two mechanics is not the pump.


Kizzy, does this only happen when the tank is low on fuel? You seemed to think in your above post that your problem acts up only when you get to a quarter tank or less. You say the light turns on after 65 miles. Is that with a full tank? Or have you realized that it always happens whether or not the tank is full? You also stated that you thought it was getting too much fuel. Has anyone pulled the plugs to see if they are black and fouled due to an over abundance of fuel? Has anyone suggested that you may have a bad ECT sensor? I was also going over some forums on the MAF issue. One guy said that his dealer got in touch with some special Nissan tech. The tech said that it was a common problem and he thinks it may be a bad wiring harness. I'm guessing it's probably the main harness that the MAF ties into. Naturally, nobody posted back with any updates.....and the post was from 2013. The guy who posted said he had gone through all the exact same things you've done. Replaced the MAF 3 times and had the car reprogrammed. After a week or so, the light is back on.
