Nissan 350Z / 370Z Reliability and Durability: Pros
YearBody/PowertrainComment
2009 2dr Hatch 332-horsepower 3.7L V6
6-speed manual RWD
My last two Nissans have each gone over 150,000 miles. Both were easy keepers, reliable, and inexpensive to service. I expect the same from this one. Servicing costs on the Cayman are a nightmare by comparison, despite long recommended service interval
2008 2dr Hatch 306-horsepower 3.5L V6
5-speed shiftable automatic RWD
Very reliable, have not had long enough to evaluate durability.
2007 2dr Convertible 306-horsepower 3.5L V6
5-speed shiftable automatic RWD
I drove this car in 15 degree weather, It cranked up the same as 80-90 degree days
2006 2dr Convertible 300-horsepower 3.5L V6
6-speed manual RWD
So far no problems.
2005 2dr Hatch 287-horsepower 3.5L V6
5-speed shiftable automatic RWD
nissans have always been know to be well built and reliable.
2004 2dr Hatch 287-horsepower 3.5L V6
5-speed shiftable automatic RWD
Relatively cheap to maintan for a sportscar. Nissan engines can run pretty high in mileage and be just fine.
2004 2dr Hatch 287-horsepower 3.5L V6
6-speed manual RWD
Strong, durable engine and drivetrain. Have only had standard maintenance - no repairs. This includes taking the car to the track and autocross on occasion.
2004 2dr Hatch 287-horsepower 3.5L V6
6-speed manual RWD
I bought mine with about 160,000 miles on it kind of as a toy as I didn't anticipate having a 400 mile a week commute. Through all that though it has been dead reliable. Here are the only issues I've had with it: - Clutch needed to be bled as pedal would sink to floor in hot weather (still operable though) - Replaced/upgraded brakes - Alignment was way out of whack and feathering front tires (common problem) - Driver's side window motor failed the day I bought it (fixed obviously, common problem, no issues since with OEM Nissan replacement) - Trunk latch and dampers were shot and needed to be replaced It starts up and runs like clockwork. I could see this car going another 100K miles in the hands of the right owner.
2004 2dr Hatch 287-horsepower 3.5L V6
5-speed shiftable automatic RWD
never had to do any major repairs on my Z
2003 2dr Hatch 287-horsepower 3.5L V6
6-speed manual RWD
Its engineered to last and the parts are reasonable, not cheap, but reasonable

Engine is a hit or miss with oil consumption.

2008 4dr Sedan 162-horsepower 2.4L I4
5-speed shiftable automatic FWD
I researched online and spoke with Optima owners. Kia has come a long way in reliability in the past few years. I was surprised by the level of owner loyalty. People who own Optimas enthusiastically recommend them.
2008 4dr Sedan 162-horsepower 2.4L I4
5-speed manual FWD
Good general reliability, which is backed by an excellent warranty
2007 4dr Sedan 185-horsepower 2.7L V6
5-speed shiftable automatic FWD
I have had zero problems with the car. Trim and everything is just like new.
2005 4dr Sedan 170-horsepower 2.7L V6
4-speed shiftable automatic FWD
Have not had to call roadside service once in three years
2004 4dr Sedan 138-horsepower 2.4L I4
5-speed manual FWD
Have had 0 problems until just recently the clutch pressure plate broke! $800 to fix and not under warranty! Not happy about that.
