Infiniti utilised the A33 series as an update for the I30 in 1999 for the 2000 model year. Engine power was up to 227 hp（169 kW） but the manual transmission was no longer offered in North America (it continued to be available in the Middle East). One key complaint many people voiced about the A32 Infiniti I30 was that it was too similar to its Nissan Maxima counterpart. To address these complaints, differences of the Infiniti I30 compared to the Nissan Maxima for both models' redesign for the 2000 model year included a more powerful engine thanks to the addition of a variable capacity muffler and an additional fenderwell air intake, different front and rear body styling, gauge cluster design, a foot-pedal parking brake (as compared to the Maxima's center console mounted lever), center dashboard design, the availability of a rear sunshade, and standard drivers seat memory. If one chose the I30t (t standing for "touring"), then the vehicle would come equipped with High-Intensity Discharge (HID) xenon headlamps with darker colored headlamp surrounds, a viscous limited-slip differential, larger 17" wheels, and the availability of a Sport Package which consisted of a rear decklid-mounted spoiler and side-sill body extensions. The rear spoiler was offered as a dealer accessory on the non-Touring I30, but the full Sport Package was unavailable. In testing, many editorials claimed that when compared to the Infiniti I30's competition, the Acura 3.2TL and Lexus ES300, the Infiniti was a middle-ground between the two, stating that the I30 was neither as sporty as the Acura, nor as comfortable as the Lexus.

In late 2001 (for the 2002 model year) the model got its most significant host of upgrades, including minor styling changes, minor revisions to the interior, new optional equipment, larger brakes, a re-tuned suspension system, a standard traction control system, and optional electronic stability control. The updated model was renamed " Infiniti I35" to reflect an engine displacement increase from 3.0 to 3.5 liters, with the new VQ35DE V6, producing 255 hp（190 kW）.

In September 2004, Nissan announced that I35 production would cease and that model year 2004 would be the last for this vehicle. It was also the last remaining front-wheel drive Infiniti since the G20 ended production after the 2002 model year. The I was replaced by the new Infiniti M which had been introduced earlier for the 2003 model year. Sales also could have declined due to the redesign of the Infiniti G, another mid-size sedan, with a coupe option, with better driving dynamics, more enthusiast-centric styling, more power, and different drivetrain options, being Rear-Wheel Drive or All-Wheel Drive as opposed to the I35's Front-Wheel Drive.

Indonesian versions were sold from 2000 to 2002 as the Infiniti I30 Standard and Touring. The later models from 2002 to 2003 was sold as Nissan Cefiro 3.0 Brougham VIP.
