r/altima

The car died on the highway, and it was apparent that the battery was dead. The battery was old, so I replaced it and that was enough to get me home.

Once home, I checked the voltage across the battery with the car running, and it was below 12v, so I replaced the alternator. With the new alternator, I was seeing 14v or so (I don't really recall, but more than 13)

Then, last night, it died again. When I checked the voltage across the (new!) battery, it was 5v :-/

I jump-started it, and checked the voltage with it running, and, again, less that 12v :(

WTF? Thoughts?

This has been an ongoing issue. My Altima is misfiring and running rough. I have changed the valve cover, plugs and coils and cleaned the throttle body. For awhile it seemed to run fine, but now it will die after a few seconds when I have it in park or idle and when driving it I can sometimes smell gas. The code its showing for the check engine is P0300 and Auto Zone suggested replacing the fuel pump. I dont want to replace the pump if thats not it. Has anyone had a similar issue? Any ideas on what it might be?

2017 Nissan Altima 2.5 SL (GCC spec) here in Abu Dhabi.

Current odo: 94,000 km
CVT fluid changed first time at 93,000 km
Engine oil changed regularly every 10,000 km
Driving mix: about 25 km daily commute, city + highway, usually 80–100 km/h

I’m getting around 8 km/L average checked tank to tank .

Wanted to check with other Altima 2.5 owners—especially GCC/UAE owners:

- Is 8 km/L normal for this car/driving pattern?
- What mileage are you getting?
- Anything I should check (CVT adaptation, spark plugs, throttle body, tire pressure, air filter, etc.)?

No warning lights, car feels normal.

Appreciate your inputs.

Went to go start my 07 Nissan Altima 3.5 and was overheating as a drive but is balanced in the temperature gauge. What does that mean? It still starts and runs but overheats as a drive. Going to a shop tomorrow to figure it out!! Need help figuring it out! The leak color is blue.. what does this mean? Do I need a new hose or water pump? Car has no check engine light

I'm currently at 230,000 kms (144k miles). I service my car regularly and use OEM parts only. I still have my original engine and CVT.

I have been extra cautious with the CVT, specially after crossing 150,000 kms (94k miles), I usually service it every 40k kms (25k miles) and have had 0 issues so far.

What does everyone's odo reading look like? It would be quite interesting to hear some tips and advice from owners with high mileage!

Thank you!

Hello! I have very recently, (yesterday), bought a 2017 2.5 SL Altima that has over 208K KM (130K miles) on it. Prior to it I haven’t had any experience with any Nissan and honestly, and I’m not very familiar with them.

The car was owned by an older gentleman and he drove it like an old person would. I asked him about maintenance and he said he was kinda sporadic with it and wasn’t always on time, and besides the regular engine oil change he wouldn’t do much else.

I heard that the transmission on these cars is terrible and breaks easily which is what I’m pretty scared of but I wanna do a full car maintenance on it changing pretty much everything just to be safe.

Is there like a specific procedure to follow with these cars and do I have to worry about the transmission much or not? Your input would be very appreciated.

Hey everyone -

How are the new 2025/2026 Altima’s? Are they proven to be reliable or still have transmission problems?

So I found this car on Facebook marketplace. It’s a 2012 Nissan Altima · 2.5 S Coupe 2D with 163k miles on it. I’m going to look at it tomorrow m, anything I should look out for?

26k miles on it. Anything I need to know yall think? Obviously I’ve test driven it and like it because it’s fairly nondescript with good gas mileage. Only downside I can see for me personally is trunk space bc I might have to move soon but I’ll make it work. Mostly just going to be a daily commenter car.

My current car is old so to me the whole Apple CarPlay thing and blind spot monitoring is pretty luxe lol

I have a 2014 Nissan Altima with around 146k miles on it.

Lately it’s been having some issues with acceleration and at times the brake lights staying on.

I have cleaned the battery terminals, replaced the brake stop light switch, and cleaned the mass air flow sensor.

The issues still seem to be returning.

For the brakes, I was wondering if the 2014 Nissan Altima needs a brake stopper grommet even if it appears that the stop light switch plunger is nowhere near the hole (it appears in the middle of the two switches).

Then I was curious if you guys think I should just buy a new mass airflow sensor for the car to see if that helps with acceleration issues?

I have a 2015 Nissan Altima S that I am replacing its IPDM. Both low beams are not working despite light bulbs are new.

If I replace the IPDM, does the IPDM require programming or is it plug-and-play, if I get a used one with same P/N that was taken out the car?
