Hello Everyone!
I'm new to the forum. Just picked up a 2008 G35S yesterday with 141k miles on it for my son. Overall it looks to be in great condition. Has the panel peeling issue that every car seemed to have. Found some solutions on here for that already, great ideas on this forum. One issue it has is the passenger power door lock doesn't work. It doesn't work with the key fob, the door switch on the door itself or the driver side door. I can't find schematics anywhere. I was wondering if any of you knew if there was a door solenoid that commonly fails before I dig into replacing the door actuator itself. When trying to lock or unlock it doesn't make a peep, so I'm thinking its a solenoid somewhere and not the actuator. I'm not familiar with Nissans at all, so any help would be appreciated.

 

I believe door lock actuator failure is common on these cars. Thats probably your issue. And no, theres no solenoid for the door lock actuator.

 

Thanks!

 

Here's a link to the FSM, section BL - Body/Locks.

This is a huge help thanks! I didn't think it was the actuator because I thought the switch on the passenger door wasn't opening any locks. I was mistaken though it does unlock/lock everything, but the passenger door lock. Pretty much confirmed it's the door actuator, yeahhhhhh. I do think my son has buyers remorse. Just bought this a few days ago to get out of his gas hog Toyota Tacoma. He didn't realize he had to use premium fuel for the G35 HAHAHAHA!!! Now he's questioning whether or not to keep it. Oh well.

 

It's not recommended but you "can" use regular gas.
I had a similar issue but my actuator was working.
The door didn't unlock. After repairing the cable it works perfectly.

 

Yeah you CAN run regular fuel, the knock sensor will pull timing if it detects a knock condition which is pretty common on all these engines.

You just aren't going to get full timing advance (thus POWAH) when you punch it wide open throttle.

I would have kept the Tacoma AND bought the G35 The Tacoma gets pretty much the exact same mileage as the G35.

 

Yep, true that. I had three little baby bouncy Nissan pick 'em up trucks (4-banger ATs) over 15 years before my first G sedanX, and both my Gs get same or better MPG around town as those things. So underpowered, the gear ratios had to be ridiculous to get them to carry any weight at all. And not even close on the highway. Never got any better than 17 mpg with those things.

 

This is true. I have been filling my car with regular gas because that śhits expensive here and the weather was cold during winter.

I have gotten engine knock twice and both times the engine was cold, and I was flooring it. But besided those two incidents, its been running fine.

 

My son is 6'1" and believe it or not, but the Tacoma did not have a lot of leg room. He was pretty uncomfortable in it. He's loving this G35 now though. Plenty of legroom and power for him lol. If he ever decides to go back to a truck he would need a full size for sure.

 

I'm on my third Infiniti since December 2005 and have never used premium except for one month tests
Regular 87 octane is fine and gives better MPG. I know because I did a one month test of both 91 and 93 when I had my 06 G35 6 speed and was commuting 2k miles/month.
Even my current Q70 runs fine on regular.

 

That's great info, thanks. Like that you ran two different tests to confirm and have the data to prove it. Thanks!!

 

Totally agree about the legroom in the Tacoma, swapped engines in my dad's last winter and test drove it for a week. Very cramped.

 

Gas prices are retarded now.

Regular gas crew.

 

I blame Biden. Soon as he took office, gas prices started climbing. That damn turd!
