I was going to post the reliability chart (since the April 2011 auto issue just came out) but found this thread already. The current I was going to post is identical to the one posted by the OP in terms of ratings.
The bottom of http://www.consumerreports.org/cro/c...-406/index.htm shows the problem rate for an average car for a given model year.
http://www.consumerreports.org/cro/c...faq_ov.htm#1.4 might also be insightful regarding the survey, as it involves problems in a 12 month window of time, for a given car.
Since I own an older Z and haven't watched the 370Z section of the board at all, I am curious to see if people w/370Zs have had trouble on those identified as trouble spots.
In earlier years when the 350Z was still new, the 03 and 04s for instance, had terrible reliability ratings for suspension (no doubt due to the infamous feathering issue) and transmission (I'd seen so many people go through at least one manual transmission). So, the results for the time, seemed quite accurate.

As I posted, I am very curious to hear if 09 370Z common probs experienced by owners here concur w/what CR reports for the 09.
FWIW, on my 04 Z, both power windows failed long ago, fortunately both under warranty. Around that time (don't look at this chart since they only represent a recent 12 months of ownership, not back when I had my power window motors replaced), the CR ratings on the 04 for either body hardware or power equipment were quite bad.
It's very possible for a set of problems to manifest themselves in a window of time, all/mostly get fixed under warranty (and thus get reported in the survey) and then the improved parts are better/don't fail.

These problems may not be "common", but they've popped up repeatedly on other 370z forums.
- Steering wheel lock sensor failure, keeps car from starting until replaced (yes, you will have to be towed to the dealer)
- ECU "whine" (high pitched frequency) coming from the ECU itself which can be heard in the cabin while the car is moving. Requires ECU replacement
- Fuel Starvation when taking a hard right turn with one quarter tank or under- all gas shifts away from fuel sensor/siphon due to design of gas tank. Car stalls, wait a minute and crank it back up. No known fix other than "don't take hard right turns with a quarter tank of gas". If you track the car, keep a gas jug handy. I'm not making this up.
- Throttle lag issues when oil temps get above 220(ish)+. VVEL may/may not be the cause. The ECU cuts throttle response to keep "damage" from happening to the engine at higher oil temps. So far, the only fix seems to be going with a new engine management system, but that also seems hit-and-miss.
- Rotor glazing/scoring under hard (track type) braking scenarios, leading to possible brake failure
- Drivers side seat wobbles in base models, requires a dealer fix
- Oil consumption requiring a new short block if the car fails an oil consumption test according to TSB guidelines
Those are the only ones I can think of off the top of my head.

The fuel starvation issue is nuts. Is it fairly easy to repro it while not tracking the car? If so and one has personally hit the condition while not on a track, I'd file a safety complaint w/NHTSA at https://www-odi.nhtsa.dot.gov/ivoq/ (you can find it if going to www.safercar.gov). It could eventually cause an investigation and a recall.

I have had this one on my 2011 Nismo. I thought I was going crazy. So next time I here it I will look a bit closer now.

I've found CR reliability ratings to be generally pretty accurate. I seriously doubt that the solid black dots for the 09 on engine cooling, squeaks and rattles, body hardware, paint/trim could all be due to lack of maintenance. Same goes for the not the best ratings for power equipment and audio system.
As I posted, I am very curious to hear if 09 370Z common probs experienced by owners here concur w/what CR reports for the 09.
FWIW, on my 04 Z, both power windows failed long ago, fortunately both under warranty. Around that time (don't look at this chart since they only represent a recent 12 months of ownership, not back when I had my power window motors replaced), the CR ratings on the 04 for either body hardware or power equipment were quite bad.
It's very possible for a set of problems to manifest themselves in a window of time, all/mostly get fixed under warranty (and thus get reported in the survey) and then the improved parts are better/don't fail.

In regards to people saying poor maintenance was the problem...
These are 2009 models. Really, they shouldn't need any maintenance besides oil change. Most are probably not even at 30,000 miles. Plugs, coolant, brake fluid, etc. don't need replacing yet.
