G37 Reliability?

How would you guys rank the reliability of the G37 Sedans? For current or former owners, how many mileage did you get until you started to find issues or problems to begin happening?

My G has been very reliable (knock on wood). I know a couple of people that have 100k+ on their G37's and other than normal maintenance they're still kicking. I chose to buy an Infiniti because I was looking for a luxury/sporty car and because their reliability and cost of owner ship is great compared to Mercedes BMW and Audi.
I'd say reliable. I have seen people have small issues here and there with electrical parts but nothing the warranty doesn't cover. Parts also aren't that expensive.
I've driven the G37 back to back with the 3 series and A4 and I think I prefer the Infiniti.

The BMW and Audi have their pros but the cost of ownership past 100+k is what scares me off.
I have only 6, 000 miles on my G37 but I do know that they and other Nissan products are very reliable. I have driven nothing but Nissans for the past 15 years. That is not a long time in the grand scheme of things but considering this is my 5th car in that timeframe, I have gotten a feel for what to expect. None of those cars broke down on me and all of them were as reliable on the day I traded them as the day when I drove them off the lot.

Thats exactly what I think too with bmw the first 50k is glorious until you past the 90k mark. Things start to get expensive and maintenance cost just goes through the roof once you past warranty with these german vehicles. Although Infiniti in the past had their slight issues with their first generation G series, they were gradually fixing the issues upon release of the new one. We all saw the improvements.
I think with other brands its more of a hit or miss. My brother has a 01 Audi TT that he has owned since new and it has almost 190k on the clock and it runs just fine. It just comes down to the car you get and how you baby it. I still think that Infiniti surpasses most of its rivals when it comes to reliability.
Maintenance is big part of it. I believe that German cars require a strict schedule for maintenance. It is not impossible to have a non japanese car go over 200k.

But it is common for a japanese car to be over 200k.
Infiniti has one of the better reputations among luxury brands. I would actually rank Lexus first, followed by Infiniti, then probably Mercedes in terms of reliability.

BMW and Audi have terrible reputations when the miles start to tag on. But Infiniti doesn't have that problem.

Generally, I think Japanese cars have better reliability than anything European. I don't really bother with American lol.

American car makers are stepping up, I know Dodge/Chrysler is doing much better than they were before, but that's probably because Fiat (Italian company) is now part of Dodge and controlling a lot of what they do.

I still wouldn't buy American
The domestics (GM/Chrysler) are doing much better than before but I still their reliability is still very much questionable. Out of everybody I hear them having the most recalls and TSBs. CFRP actually explained it the best, and that Euros need to follow a "Strict" maintenance schedule to run in good working order.
I had a customer come in with 230K miles on his 2004 G35 with original trans and motor.. These cars are rock solid..

It is funny because the EX, FX, G had little to no recalls TSB's and the QX When it was built in USA had many recals and TSBS and now the JX also has many recalls and TSB's and it is also built in the USA... NOt that the QX is on the patrol platforn the reliability has got a lot better!
Where Infinitis made in Japan at one point? Which ones are still? I've noticed that some of the newer Infiniti vehicles that are made in USA have had a bunch of recalls.

Sorry not too knowledgeable about what models are made where. I just know the new JX, and Pathfinder has a crap load of recalls.
My G37 has been very reliable to me. I haven't brought it back for any issues apart from some service recalls that I did not even notice. I have faith in Infiniti.

The VIN will tell you from the first letter, from last check all Infiniti's I have run across have been made in Japan.
I've had my G37 for 2.5 years and I've had to pay $0 to fix anything on my car right now. The only money out of pocket that I've had to spend on the G37 have all been external stuff/cosmetic (wipers, dents, dings, windshield repair...etc).

However, I've got 24k miles on the car right now and I'm thinking I'll need to replace the tires by the end of the year.
My 08 coupe: bought in July 2010 with a lil over 26k, I now have 130k. Up until July 2012, drove 120 miles roundtrip to work not including errand runs, business and liezurely travel. I had the engine replaced at 61k and replaced the clutch since the engine was apart from the transmission. I now drive 60 miles roundtrip to work as well as business and leizurely travel.

I have had to replace a battery, an idle pulley, brakes and rotors (2x), an air flow sensor and some other small issues due to wear and tear. I will be replacing a sway bar soon, and as soon as I figure out if this PA200 code, I will be replacing what that issue is too.

Outside of replacing the engine (thank goodness for warranty), and considering the amount I drive everyday, I feel fortunate not to have had any real serious issues.

I've had a few G's but the most I've driven is 50k miles on any one. Never an issue. Total between 3 cars so far is about 85k miles. Only repair was some moisture that got behind the glass of my speedometer once and my last xS had brakes replaced early (at 12k miles -dealership replaced for free). Otherwise, normal maintenance.

Wow an 04 with 100k?

You don't drive much!

I have a 2004 that I bought in 2006 with 19k on the dial and it's a hair over 118k now. That's what, a little less than 7 years for 100k. Nearly 15k per year, mostly in town and one or two 1600 mile round trips each year. I'd say 100k is a little low but some leases are 12k yearly. Average yearly ends up being somewhere between 12 and 15k depending on where you live I think.
