Today, in this video, we're gonna talk about the top five problems in our Infiniti G35
third generation.
Number one is cutting out, engine light on with a code for like a cam sensor or crank
angle sensor.
So, driving on the road, cuts out, box stalls, excessive crank.
Infiniti did have a recall on some models, so if you want to know if your vehicle is
covered under this recall, just call any Infiniti dealer with your VIN number, and they can
tell you if the program has been taking care of or if your vehicle had been taken care
of.
So, the location of the crank sensor is down below.
So, there's a plastic shield you have to take it down.
And then it is located right here in the bell housing to the automatic transmission.
Our model happens to be an all-wheel drive, an X, G35X, but it's gonna be located in the
same spot whether you have all-wheel drive or not.
And then the cam sensor is up top.
And don't forget, on the 3.5-liter, you have two cam sensors and one crank sensor.
Number two, brake lights stay on.
So, if you notice that your brake lights stay on, your foot is off the brake pedal, obviously,
you can get out, and they're extra bright, they're on, there is a problem with the brake
switch on these.
The switch itself gets stuck.
Most of them are made out of plastic.
It's not uncommon for the gear in that to bind up.
So, location of that is in the driver compartment right above the brake pedal.
So, the brake switch is right here in the driver's seat, located right underneath right
above the brake pedal.
You can't miss it, it's really easy to access, and it's easy to replace.
It is a brown switch with a tan connector with two wires going into it.
Also, with replacing the switch, check your fuse that goes to it because a bad switch
can actually trip the fuse.
So, I don't want you to put a new brake switch in and then say it still doesn't work, now
it doesn't work at all or...
So, double-check your fuse.
If the fuse is popped, don't think it's just the fuse because more than likely the mechanical
part of it, the electronic switch triggered and broke the fuse.
So, check both of them out.
Number three is an erratic idle after cleaning the throttle body.
So, these G35s are notorious for a light cleaning on the throttle body needs to be performed
quite often, I would say probably every 20K.
You just need to do a little cleaning on it, then it should go, but you might get an erratic
idle after, and it's really no big deal.
What that is is basically the PCM, the module is what we call searching and looking for
the proper air-fuel ratio, and it's taking calculations.
It eventually will straighten itself out.
So, you don't have to worry too much about it.
You didn't do anything wrong, hopefully.
And once you get on the highway, steady speed, it'll adapt and ready to go.
On this particular model there is electronic throttle.
So, it's not a cable operation.
It has a little module sensor up here located, and it connects wires to the throttle, your
gas pedal.
So, if you force this butterfly open, you're gonna break the calibration off, and then
you're gonna hold in a bunch of problems.
So, all you need to do is take a nice little throttle body cleaner, put some eye protection
on, and spray right in there and you wanna get rid of all that carbon.
You can use an old toothbrush, like a bristle brush, and just clean it, but do not push
on that butterfly.
By butterfly, I mean this plate right in here.
In the old days, you can push this with your finger and have no problem, but now with this
model and design nowadays, you'll set another code.
Number four is timing chain.
If you own a Nissan, you're aware of this, but don't take that tapping noise lightly.
If it starts, get it fixed, checked out right away because what it's doing is giving you
a fair warning about a failed timing chain.
These are notorious for the guides and the tensioner breaking down.
So, the guides are like a plastic sheeting that it gets mounted to the front of the block,
and the chain goes around.
So, it goes around the cams, down the chain to the crank, and then you have a tensioner
that goes on there.
The tensioner will get actually clogged if you do not do frequent oil changes.
You've got to keep up with the oil changes.
You have any, like, ticking started, don't push it aside, get it checked out and get
it replaced.
Number five is the filler neck hose located here where the gas cap is.
Open your door, you can see the gas cap right there.
Go underneath, right below it, and you'll see what the filler neck is.
Let's take a look.
So, if you follow the filler neck, it goes to the gas cap and down inside this fender
well.
And you see that plastic cover?
Don't bother taking it off because it's all metal underneath there, but it turns into
rubber down below.
So, if you follow the filler neck, it's a steel tube all the way down right here over
the actual rear suspension, and then it turns to a rubber right here, and then it goes right
into the gas tank.
Now, I can actually see the metal part is rotted, and it's starting to split the metal
where it goes into the rubber hose.
Infiniti did have a recall on this, so once again, just call your local dealer if you
don't think this has been replaced, give them your VIN number, and they will be more than
happy to help you out.
