Review of the 2003 Infiniti I35

  • Though not as luxurious as some peers, the I35 is powerful, reasonably well-equipped and a good deal -- so long as you don't mind that it's a Maxima in disguise.

  • Safety
  • Pros

    Outstanding V6, pleasant highway ride, low price, spacious cockpit, easy-to-use controls, strong reliability record.

  • Cons

    Too similar to the Nissan Maxima, some cut-rate interior materials, sport package gives the car a choppy ride on rough pavement.

Amazing car!!! will always drive

by on
Vehicle: 2003 Infiniti I35 4dr Sedan (3.5L 6cyl 4A)

Although this Infiniti is my first car, I must say what a dream it has been to own. I bought this car in early 2012 with 117,000 miles on the odometer and have since put on close to 20,000 miles without a single problem. Gas mileage is very good for 134,000 miles averaging 25mpg between highway/city driving. The performance was top notch for it's time and is still a high level competitor today. Car drives great on the GLE suspension and the 215/55/R17 tires make for a nice mixture of ride comfort and handling. The car truly is a low end sports car with great luxury features and very good interior quality. Very little I would change about this car...will always have one.

Great value

by on
Vehicle: 2003 Infiniti I35 4dr Sedan (3.5L 6cyl 4A)

Peppy vehicle with poor turning radius. Very dependable. Only problem in 8 years has been the automatic portion of the electric windows (when you hit the switch and they go all the way up), it comes back down 4". If you close slowly it is fine. Comfortable and a great deal and value for the money. Consumer reports his listed this model as "great used car value" for many years.

A fast sleeper

by on
Vehicle: 2003 Infiniti I35 4dr Sedan (3.5L 6cyl 4A)

This is my 2nd Infiniti, my first is a 96 I30t (still own) If this car holds up like the 1996 model I will be a satisfied customer! This is a fast highway car, passing cars has no strain or sweat associated with it. Seats are comfy everything works, stereo slams but not distorted. Fuel economy is freakishly good ( my trip computer lines up with my manual calculations 34-35 mpg going 65 mph in Ohio and PA roads! (no kidding 34-35 mpg) Smoothness and reliability are the trademarks here, looks good too.




Much to be improved upon

by on
Vehicle: 2003 Infiniti I35 4dr Sedan (3.5L 6cyl 4A)

Was a fantastic vehicle until it passed 60k miles. Even with continuous maintenance, it sucks gas, has serious suspension problems, eats through tires, burns oil, the transmission is going, and the muffler has rusted completely off. It now has 68,000 miles on the odometer and has eaten $5000+ in repair costs. It has also left me stranded 1000 miles from home when the TPS (throttle position sensor - once recalled) died. That out of town repair was $1000 alone.




Solid car for the money

by on
Vehicle: 2003 Infiniti I35 4dr Sedan (3.5L 6cyl 4A)

I bought this car looking for comfort, performance/sportiness, luxury/sleek elegant look and a bit of exclusivity. 12k miles into it I've found all this and then some. Among the competition, (es300/TL), I went with the i35 due to its performance (3.5L versus 3.0, 3.2), comparable gas mileage (20/26), comfort in the little things (sunshade, rear heated seats, sojourner leather), build quality and reliability (its a maxima in disguise). TL's and ES300's are a dime a dozen, this car was Infiniti's hidden car. Its nice to roll in a car that has a lot of everything, yet isn't seen 5 times in 1 in block. The ride is very smooth and no major issues have arrived.




Best car i've had

by on
Vehicle: 2003 Infiniti I35 4dr Sedan (3.5L 6cyl 4A)

This car has given me absolutely no problems in the past 6 years I've had it. Recently I was hit by some object on the freeway. The windshield withstood the impact with just a small scratch. I think I would have been in trouble had I not been in such a sturdy car. I love the performance and the reliability.
