The sunroof has a drain that has a plastic part. The part failed and water was penetrating the cabin. This is not covered by warranty. However, the dealer and Infiniti covered this under goodwill; and I paid a nominal amount. The repair itself was very time consuming but the part itself was rather inexpensive. This to me seems more like a manufacturing defect

Water penetration into cabin. Problem lies in sunroof drains that become blocked. This is a problem noted in various YouTube videos and G37 owner forums. I was able to get this covered by virtue of an extended warranty Arguably the terms of the warranty do not cover water leaks. However I was able to induce the dealer to repair. This requires replacement of the drain hose (only the two front hoses; although there are also two in the rear of the sunroof opening) and the drain hose grommet which passes through the firewall and allows water to drain to the ground. This problem is very disappointing to me. I like the car very much. This is a design defect and Infiniti should be embarrassed. Our other car, a 2004 Lexus RX330, has a sunroof and we have never had a problem.

Check Engine Light came on. Very erratic. Very frustrating since no engine performance issue manifested. Codes referred to a possible ECM defect. Expensive repair. However dealer technician carefully investigated and diagnosed a broken wire in the harness. The repair required a soldered wire and rewrapping harness. Problem eliminated. I was actually impressed and pleased with the technician's work. It was expensive; but it required a lot of testing of wiring in the harness and in a way I was paying for the experience and knowledge of a good tech person

I don't consider this brake job a problem. It was just normal wear and tear. I can't remember if they required this fix for my safety inspection or not. The brakes never malfunctioned. I have zero complaints about this car. Haven't had any problems or issues with it to date. Just normal maintenance. Dealer had said the G37 tends to need brakes replaced faster than the average car. He speculated it could be because people who choose this car like to drive fast. True for me!
