I have a 2004 sedan and it has been bulletproof. It has the older VQ35 which I believe is used on the Hybrid. The only 2 issues it had was a wonky throttle body, replaced free under warranty, and the stupid design of the spark plug seals molded into the valve cover. Around 80k miles the seals go bad and a few drops of oil can get into the spark plug heads. This requires replacing both valve covers at about 500USD each plus labor. There's no functional problem with it, it can stay that way for years without causing trouble, and I hope they changed the design in the past 9 years.
Reliability Question to Infinity Owners - Seeking Help
Hi Q50 Forum Members. I am enjoying very much this forum and find very informaive and fun!!. The more I look at the Q50 info here and elsewhere, the more reasons I am finding to serioulsy considering buying it. I would be very interested to hear from G37 owners about their engine and transmition realibility, since these apparently are being used at the Q50, conversley, I would like to hear form the M Hybrid owners on the their Hybrid experience so far (again regarding its reliability). I have been driving beamers for the past 20 yrs, and as far as the driving experience is concerned, for me it is really great experience, but.....I find their Nav and overall interface to be lagging behind the times and becoming outdated, I played with the INtouch simulator that someone posted, and it is a significant improvement over BMW's interface (assuming that they can get the bugs out and get to work fast and realiably). Well, sorry for the long post, but I felt that I had to put my question in proper context for your help.
Message to Inifity Chick: I don't mind at all if you can send me a two page response on your current experience with your G37, your writing skills are second to none!!!, anjoyed your report very much (and I knew you were going to choose exterior White, that seem to be a color that is not too compromising).
p.s. I am writting this from overseas and looking very much forward to driving this car next week when I return home. I hope I don't get disapointed (last time I drove my daughter's Corolla, it felt like driving a go-cart, no disrespect to the Corollal owners, but, when you get used to a heavy car, that is the sensation you get in a lighter car)

AFAIK, the only engines that had problems were the first revup VQ35's they put in the coupes. Alot of them had oil consumption problems and were repaired or replaced under warranty. The drivetrain is so ubiquitous across the Nissan and Infiniti lineup if there were reliability issues you would have heard about it by now.
