2003 Infiniti I35 Review

A nice Japanese sedan with plenty of luxury and safety features.

Reviewed by Automotive on


The 2003 Infiniti I35 isn’t going to be the flashiest or fastest sedan available in its class. However, it does have plenty to offer the right buyer, and is attractive with a comfortable cabin and plenty of standard, safety, and convenience features available. Its 3.5-liter, V-6 engine has more than enough power to take care of the daily commute, day-to-day errands, and whatever else the driver may need. Highway driving is smooth and comfortable. Overall, this is a good choice for the car owner who wants lots of reliability and dependability as well as an attractive body design and lots of safety features. In consumer reviews, it does very well and seems to be well liked by its owners.

What's New

The 2003 Infiniti I35's front seats are now adorned with the Infiniti logo embroidered on the cloth. It's also has more wood trim on the center console and offers a new satellite radio option.


The 2003 Infiniti I35 looks like what it is, a nice, unassuming sedan perfect for families, professionals, or older people looking for a reliable car. It features a new sunroof, rear sunshade, and body side sills. It also has an assertive front end and grille with prominent headlamps, and the Infiniti logo located in the center of the grille. The bumpers are painted to match the rest of the car’s paint, giving it a cohesive, elegant look. The rear end features a nicely sloping line from the car’s roof to the trunk area and easily visible turn signal lights and parking lights.


The 2003 Infiniti I35 has received complaints that some of the materials used are lower quality than some of the model’s competitors; yet, the overall look and feel in the cabin is very nice. Both the driver and passenger seats are adjustable for the perfect fit. These seats are bucket style with a power adjustable lumbar support system in the driver seat. The back seat features its own ventilation ducts, offers an armrest with storage in the center and is split folding for additional cargo space. It also features power accessories such as mirrors, door locks, and windows. The front console also has storage along with the front and rear door pockets. Cup holders are conveniently spaced in the cabin as well. Cruise control and a tilt adjustable steering wheel are standard for the driver’s comfort. Controls for the cruise control and the car’s audio system can be found on the steering wheel as well. Speaking of the steering wheel, it is wood and leather and adds a nice, elegant touch to the interior. Leather trim accents the dash and faux wood can be found on the shift knob, doors, and center console.

Performance & Handling

The 2003 Infiniti I35 is well equipped with a 3.5-liter, V-6 engine capable of 255 hp and 246 lb-ft of torque. The company chose to pair this powerful engine with a four-speed automatic transmission. While the powertrain promises a great deal, it overall performs adequately in most situations. This isn’t a car to expect great, sport sedan-like performance from, though it is well known for its reliability. Depending on the owner, this trait could be more important than speed and race car like abilities. The suspension system offers a comfortable ride, especially on the highway.


In addition to its reliability, the 2003 Infiniti I35 has a list of safety features almost as long as its list of standard features. This car is equipped with four-wheel anti-lock brakes, front and side airbags, and front side mounted airbags. It is also equipped with traction control, head restraints designed to protect the car’s occupants from whiplash injuries in the event of an accident, and emergency braking assist. For parents or child caregivers, it offers child seat anchors and rear door child safety locks on every car as well. Seatbelts with pre-tensioning abilities are located in the front seats for additional security.
