Cause for the dreaded P0011/P0021 codes that everyone is curious about - G35Driver
link says it is a front timing cover problem? I'm confused.
It's indeed the rear cover gasket, the one that's the most PITA to replace

Out of sheer curiosity how do g37's respond to mods?

Maybe one of these days I'll go for a tune and or full exhaust.

Are there many parts available? Do they run reliably when modded?

I'm asking because when Legacy GT went from 4th gen to 5th they they lost the wrx rumble due to headers being equal length and a lot of the parts don't fit due to a different design.

My car ate 2 rear ends in the last 2 months ... but it runs high 12's LOL!

Very little customization necessary for the typical bolt-on mods to this car. And you've got a decent rack of manufacturer and vender choices, because much of the power/handing mods that are pursued by the Z crowd are available to the G. However, from what I've been reading, and in context to your interests, bolt-ons and a tune will still only catch you a few tenths in your 1/4 mile activities, which I'm guessing is normal for $3K of bolt-ons, give or take.

Take all that with a grain of salt, as hearsay over experience. Better yet, go read up in the racking/track subforum: Motorsports / Track - MyG37

I was going to say that 3k for ~ 0.5 in 1/4 is pretty bad but I forgot that this is a NA v6 :P . ECU flash from a cobb access port got me from 14.0 to 13.5.

My car should be up an running in a week or so. At that point and time I will most likely start visiting dealerships.

I'll probably start with the closest ones to me or the ones with the most desirable cars. However usually the most desirable cars are located at the small or shady looking dealers ...

G/L with your search and a big hats-off for taking the time to do your homework and ask the right questions, that should be time well spent. Look forward to seeing what you find

Apologies for bumping an old thread but I finally did it ;P !

Gray 2012 G37x with 39k miles.

I should have asked this before but what kind of mpg are you guys getting? Gas mileage could be better lol.

My trip to work is maybe 3 miles city / burbs + 12 hwy (2 in traffic) and going back its maybe 6 hwy and rest city little traffic and I'm averaging 18 mpg ... ... ...

Given what you described, 18 mpg is all you can expect... but I'm sure you knew that before you bought the car.

I'm also in a 2012x, get 21.5 per the car's computer, 30 miles city/burbs, 94 hyw daily. Some people say the car's computer isn't too accurate (represents better mpg than actual). I know it's not the most practical, but it's worth it to me to have something I can enjoy a bit on such a long commute. I wouldn't be able to handle having something at 30mpg that couldn't pass a semi on an incline.

I drive city/small hwy (the kind with lots of lights, and sometimes traffic), and get around 20 mpg. Good enough for me, I sure didn't buy this car for its fuel economy.

Tranny Issue

Not trying to jack your thread but I recently had to swap out my 62K Transmission on my 2012 G37xs coupe,
One day on the highway she just starts revving but not moving over 38 MPH on a 65 MPH stretch of highway..
It was a pain in the *** but worth it, Got a Brand new Q50 tranny in her at a great price.

My biggest concern would be related to model / year specific issues that are very difficult to get rid of.

For example my 2010 Legacy GT had a very soft stock suspension that used to sway at higher speeds when on the highway. My 2001 Cadillac Seville STS had vibrations at 60+ as well. Trans ams had weak rear ends etc ...

My research so far as led me to believe that there might be transmission issues with G37.

Is this true for 2010+ models?

Are there are any other issues that might be expensive to fix or hard to get rid of?

Reliability?

Thank you for your time!

You didn't jack the guy's thread but you did delve into the dark art of thread necromancy. It had laid dormant for four years until you revived it this morning.

Making a new post would have been better. What year Q50? I assume it was the V36 and not the latest redesign (V37?)
