2009 Infiniti G37x S 3.7 atmospheric from North America


Serious job by Infiniti!


Transmission shifts were very rude, but the dealer reprogrammed it, and it's worked smooth since then.

Shift-tronic on the steering is too slow to shift gear. Better keep it in the automatic mode.

General Comments:

Nice on acceleration and sounds great!

Seats are comfortable with the Sport package. Interior is roomy, and the finishing of the cabin is sober and classy.

Push the "snow" button and the car becomes a tank over the snowy conditions!

Absolute reliability for 3 years!

I own the exact same vehicle and I would write the exact same comments!

Fast, luxurious and reliable car. Highly recommended.

How many km do you have on it? I'm considering buying a used sports sedan/coupe, and the G37 seems to be one of the most reliable options...

I had several minor problems with the car. The seats wore pretty quickly upon owning, but the dealer had no problem fixing it.

The battery also died quickly after buying it, but the dealer was amazing. They actually put a larger battery in it, so it wouldn't happen again. So while the reliability hasn't been perfect, with the amount of technology in it, I am still happy.

General Comments:

First of all, this is an amazing car.

I am a younger person, and when I was car shopping, I found this car for very cheap, even used. When I found out it cost just a bit more than an Impala, I immediately bought it.

The car performs amazing through turns and general driving. Even in winter conditions with summer tires on it, it still handles decently well for a performance vehicle. However, a lot of people think it is supposed to be the fastest car on the road. It is not, I still consider it more comfort oriented, and it will not outrun a Corvette.

The only complaint I have with the car is the gas mileage. While it might not be as fast as some of the more sport oriented cars, it eats gas like it has a V12 in it.

Infiniti dealers also seem to be top of the line also. I have been to pretty much every dealership, other than Bentley, Lamborghini etc. And compared to the other Japanese dealerships, they are much less rude.

Every other dealer I went to, seemed like I should be thanking them for being able to even look at a car of theirs. This includes the American and German companies also.

I would suggest to anyone to take a look at infiniti if you are looking for a more sporty ride, while still being comfy. But again, if you want pure luxury or pure sport, go somewhere else; it is somewhere in the middle in my opinion.

2009 Infiniti G37x 3.7L 328HP from North America


Almost perfect!


While driving the car on a hill at low speed (about 30 km/h), the transmission would get stuck on the 2nd gear (safety mode). Strangely, the problem would disappear when I would turn the engine off. I brought the car to the dealer, but they could not find anything wrong with the 7 speed transmission. Then, it happened a second time in very similar conditions. Took the car to the dealer, but again, they found nothing wrong with the transmission. This time, the dealer decided to reset the software (transmission management software).

When it happened a 3rd time, I went straight to the dealer... on the 2nd gear (!) to have the mechanic test drive the car while experiencing the problem. It appeared the dealer had seen other G37's with the same problems since my last visit. According to the Service Mgr, Infiniti had found a bug in their program and they were still working to solve the issue (reprogramming the software). So the dealer could only reset, one more time, the software. It's been 5 months since my last visit and the problem has not reoccurred. Still, I have never heard back from the dealer regarding the new version of the software Infiniti promised.

The other problem I had is a cracking noise coming from the windshield. It was easily fixed by the dealer, but can't remember what they did exactly.

General Comments:

At first, the transmission problem has left a sour taste in my mouth... especially on a car with a price tag of over $40,000. But since the problem has not reoccurred, all I could say is the G37x is a wonderful car to drive. You really feel the road, and the handling is simply amazing.

Also, the seats are comfortable, and the G37x has a VERY quiet cabin.

In the snow, the 4WD does the job very well, and has nothing to envy of the competition.

Finally, the G37 has perhaps the most beautiful design in its category.

It is the Japanese BMW, with all of the problems of BMWs, namely shocking reliability and the ability to put a smile on your face. I find BMW and Infiniti make very good passenger car 4WD systems.

I currently have my third and fourth Infinitis: a G37x and a Q50. They are as trouble free as any car I've had, requiring no maintenance other than oil changes. BMWs, on the other hand, are best leased, since one doesn't want to own one off warranty.

You were trying to say Infinitis have problems like BMW??? Not in your lifetime dude; maybe you want to wish they would have problems like BMW and other German manufacturers, but never. BMW and Mercedes, you pay for the name; their reliability ranks among the worst. Japanese cars are a million times more reliable, and only every so often will it have any problems besides regular maintenance. My G35x never had an issue from brand new until I sold it 4 years later.

I agree with you 100%, and Mercedes as well.
