Looking to purchase a sedan in the next day or so and need to know what would some potential deal breakers be. Any noises, oil leaks, interior issues, etc. to look out for? Any insight and contributions would be helpful. All i found upon searching were the 2012's had an upgraded gasket. Thats about it. Thanks in advance

 

If you can expand your budget just a bit I would consider that 2012, that gasket issue can be over $2k to R&R, other than that there's not much to be concerned with as long as you give it a good inspection. Taking it to a trusted mechanic if you're so inclined is always a solid plan before sealing the deal.
G/L w/ your search.

 

Like blnewt said, if the rear timing cover gasket has been replaced, that's great. Otherwise, consider a 2012 - 2013. If not, the odds are still in your favor. It's only a familiar problem on the forums, and even then.

If the original CSC had already been replaced, that's a plus. Unless the RWD-Sport you're looking for is an automatic, in which case... yawn.

If the diff bushing had already been replaced... also a plus.

That's about it. Pretty solid car.

 

Check the sun roof drains.

Make sure auto-up works on all the windows from both the individual controls and from the driver door master panel.

Take a peek at the back of the differential looking for dark fluid indicating a ruptured viscous mount.

 

Ok thanks guys. I dont see any 12-13s around for a good deal. Ill check the rear of the engine and diff for any leaks. Upgrading from a g35 coupe and sedan

 

Actually it's not the rear of the engine, it's the rear timing cover in the front of the engine (there's a front and rear cover behind the front engine cover).

And there won't be external leaks, it's a paper gasket that seals the oil passage going through the timing case, so it's leaking inside the timing case. Once it gets soaked it can tear & break away, this results in lower & lower oil pressure

By the time your oil pressure warning code comes on it's too late

The newer models have an improved metal-lined gasket that won't tear away.

FWIW, our 09 has 90k miles and solid oil pressure. This issue isn't inevitable but it occurs often enough that it needs to be something to keep in mind when shopping for these cars, and one significant thing not to worry about if you can find a 2012+.

 

And make sure it's an actual g37S. Make sure it has the bolster seats, Akebono brakes. ETC. A lot of used car dealers advertising G37 as Sport models when they aren't.

 

Thanks blnewt. Does anyone have any pictures of this area. Maybe something to lookout for to see if by chance it has already been done?

Ive owned G35's for a while and definitely know the differences between these regular journeys and the S models. I would not buy anything but an S

 

Spend $100 on a professional pre-purchace inspection.

 

Definitely go for a 2012+ if you can find a decent deal on it. Most cases of the timing cover on the earlier models usually happen when the car reaches high milage, though I've seen cases where it occurs as early as 70k.

Didn't even know the issue existed until I started surfing through the forums. I hate having that "I'm one pull away from having a hefty repair bill" feeling in the back of your head

 

Oh hey, that's encouraging. I don't expect I'll ever see 70K miles on this car. Close, maybe. Knock on wood.

 

Just copped a 2012 g37S and sad to see this thread a week later

 

why are you sad, you found a 2012

 

Ha that was TYPO I Bought a 2010 !!! Good catch!!
