Literally bought an 06 this morning. I wasn’t too familiar with the car until a couple months ago I was scrolling looking for a decent used 350z and one of these popped up. I love these cars.

[Turtlefarm]

Love how she explained everything. Very intelligent lady.

[baldpnoy]

No mention of the Gas gauge and Instrument Cluster issues?... Probably one of the most common issue with this car.

Friend of mine has a 07 an it has 407k onit an still running strong love these cars very fast too fully loaded

I just purchased a 2004 G35 with about 153k miles (I know high but I don't drive too much and the cars last AT LEAST 200k on the engine if you treat it right)
I want to include a list of issues I have had to add on to 1A's video
The list will be helpful for anyone looking to buy a G or already has one and to see what problem may arise.
1st- The window motor & regulator
Never had such a problem with ANY car in my life then a G35 with the windows!!
If you are unlucky then the windows will go down and not come back up! Better make sure you have a tarp!
I had to replace BOTH driver and passenger motor & regulators
Also from some research I have done the sunroof may have issues but luckily I have been safe on that for now.
2nd- Crankshaft & Cam Sensors
1A had this one the sensors go bad after about 100k from what I have researched so if your G has more or coming up may be a good idea to replace them as bad sensors can cause your car to stall/turn off completely in the middle of the road! Scary!! I would recommend replacing them all at the same time if you can if not both bank 1 and 2 then later the crankshaft.
3rd Misfires These VQ engines are prone to misfires from bad spark plus bad coil packs bad valve cover gaskets ETC. In my case I just had gotten my valve cover gaskets replaced as well as my transmission fluid changed and pushing the pedal to the medal as the kids say I had a misfire in the forum in code P0305 which is a misfire in Cylinder 5.
In my case I'm still figuring out the cause but I'm sure its a bad spark plug/coil pack as these cars from 100k need a good tune up to keep the running strong.
Hopefully your G is alot better then mine drive fast turn safe!

How in the world did she not mention the internal electrical issues?! Had my HVAC control stack go out so many times on my coupe back in the day.

What a breath fresh air..great Presentation

[alexandergarcia]

I have a 04 coupe been having it for 5 years only problem I had with it with my radiator cracked they are really reliable cars as long as you take care of them and always remember to check your oil it’s just a VQ thing

[vkde]

I've had 2 G35's, never had 9/10 the problems mentioned here. The one we did have was the crankshaft position sensor. Also common are the oil burning issues, cam cover oil leak leading to ruined ignition coils, and the seat airbag repeatedly sending an error.

Before cleaning the "Butterfly" disconnect the Battery. This might prevent you from getting a code or having to perform a idle relearn foot dance procedure to correct now induced idle problems. The Throttle body throat accumulates soot and should be throughly cleaned.

[kxngearner]

I had 3 of these a 2004 RWD red a 2005 AWD black & a 2006 RWD silver all were Sedans I loved all 3 were great cars I only changed the crankshaft senor and bank 1 camshaft sensor in the 2006 these G35 are awesome just buy one from someone who has maintained it properly

[chchcheatas]

Major issue with engine shuts off randomly at stop light and sometimes on highway. I Replaced crankshaft sensor, spark plugs, cleaned throttle body, manifold and maf sensor. Still same issue. I’ve been searching on forums and others are having same issues.

[johnathannorton]

[The-Warm-voice]

These are minor problems and are considerd consumables.but if you want the real problems.they are found in BMW🤣🤣🤣...i love japanese cars i don't like Germany cars ...well nice video👍 i almost forgot Do you know i japan call it this infinity g35 skyline sedan

[johncoffey]

That brown brake switch tan connector is not for the brake lights the one right above it goes to the brake lights had to replace the garments on mine last week. The lower switch has something to do with the trany from what ive read still figuring out what it actually does thinking mine might be bad i step on the gas an lag until 3k rpm then she shyts an gets

[dope]

is the filler neck hose issue related to the not letting gas in? Im having problems filling up the tank, gas nozzle trigger keeps turning off.

[WhyDoIDriveAMustang]

looking at one sitting at abt 160k i wanna know if there’s anything i should be worried about involving the transmission. my last car just exploded it’s trans, would be nice to avoid that

[pirihern]

Don't own one, but still good to know. Have you done a 2006 su aru sti yet?

[booya]
