The shifter (automatic transmission) moves through all the gears but nothing changes and I am stuck in reverse

Just curious about the best battery brand for my car.

It makes a squeaking noise while driving, mainly when you first start going and coming to a stop. It sounds like it's around the tires and it's not an engine issues or belt issue.

After taking the seat out from cleaning under them, the passenger airbag light stays on, even when someone is in the seat sitting.

When the car is running the car with the key is not showing.

I think that what's killing my battery over night

The AC Blows but not cold (I'm sure the compressor isn't coming on). I decided to disconnect the battery just in case the AC problem was an electrical problem and now the vehicle won't start without a jump. It turns over forever but won't crank. Could it be a battery issue?

Checked fuses,fuel pump seems to be engaging,but one problem that I have is I can't find the port hole to check fuel pressure?put in new battery

I changed water pump on my 08 pathfinder. It is not releasing back on chain but the chain is tight is this correct?

Right after changing my rearbottom spring mount?

I have been chasing VDC problems with a myriad of "guesses" for solutions including a $4300 translmission that only made it worse I need to give up on Nisson. I can't afford to pay for the "fix" of the day.

there seems to be something mixing with my coolant.
the overflow bottle and the radiator has some milky looking solution in it.

2013 intake manifold repaired after engine light came on. 2014 evap emission canister replaced after engine light came on. 2 weeks after took car in for smog check. Almost immediately after engine ran very rough and I felt it was "sputtering". Intermittently. Brought in to dealership. They pulled the code for 4 th cylinder misfire. They moved the coil and spark plug to different locations and had me drive it. Ran rougher than usual and 2 weeks later misfire occurred again at the 4th cylinder. They concluded it was fuel injector. They replaced for $700. Same day I took home had same roughness and sputtering and again intermittent. 2 days later another misfire. Took to independent shop. They did the coil and spark plug move. Car ran beautifully for them for 20 miles. I take home and within days rough riding, sputtering, and service engine light soon flashes. They say my motor is good and this is electrical due to the intermittent nature.. They all say not the fuel pump, or vacuum leak, or valve issue. None are suggesting a compression test . . I had them flush the radiator and transmission to insure colors were proper and no contamination. They said all good there.not sure what to do.

My jeep was working fine and then as i came out the grocery store it wouldn't fire up. I ruled out the battery after i realized all the lights, AC, windows and stereo worked fine. I even tried to jump start it with no luck. I don't even hear the starter trying to work. Checked all my fuses and they seemed fine. My friend suggested that the immobilizer has been activated for whatever reason, which i don't know why cuz i only own original keys. Can somebody please help. I don't want to have to get a tow truck to pull it to the dealership so they can charge me an arm and a leg to get it working in 15 minutes. Heeelllllpppp!!!!!!
