Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2003 I35.

Body PASSENGER CAREngine ElectricTransmission Automatic 4-spd

The 2003 Infiniti I35 Electric arrives as a passenger car propelled by an electric motor paired to a four-speed automatic transmission, a configuration that distinguishes it within the model's 2001–2004 run. This model year recorded the highest owner complaint total of the span at 95 reports, with the engine category leading the tally and five recalls issued. By contrast, the 2001 model logged just two complaints, underscoring a sharp reliability divergence that positions the 2003 as the most troubled iteration of the lineup.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs at 105,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The federal record for the Infiniti I35 shows a significant upward trend in complaints from 2001 through 2003, peaking at 95 complaints for the 2003 model year. This represents a sharp increase from the 2 complaints seen in 2001 and 76 in 2002, before the figures declined to 35 in 2004. The 2003 model also shares the generation's highest recall count of 5 and saw an increase in investigations to 3, up from 1 in 2002. Primary complaint areas for 2003 were Engine and Engine & Engine Cooling with 22 reports each, though the data does not specify the root cause of these issues. Because this year represents the peak of consumer complaints and is tied for the highest number of recalls, it is not the ideal year to buy.
