The 2003 I35 is essentially a rebadged Maxima with the VQ35DE V6—solid powertrain, but the front-wheel-drive transaxle differential and subframe bushings are ticking time bombs that make or break ownership economics.
Front Differential Failure in Transaxle
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Grinding or whining noise during acceleration or turning, Vibration through steering wheel under load, Visible metal shavings in transaxle fluid, Loss of power transfer to one or both front wheels
Fix: Front differential bearings and gears wear prematurely in the transaxle case. Requires full transaxle removal, case splitting, and diff rebuild with new bearings, seals, and often ring/pinion set. 8-12 labor hours. Many shops won't touch it—easier to swap a used transaxle, but used units often have same wear.
Estimated cost: $2,200-3,800
Subframe and Bushing Deterioration
Common · medium severity
Typical onset: 100,000-150,000 mi
Symptoms: Clunking over bumps from front end, Steering feels vague or 'floaty' on center, Visible cracking or tearing in rubber subframe bushings, Uneven tire wear on inside edges
Fix: Front subframe bushings deteriorate and the subframe itself can crack at stress points. Full subframe drop required to replace bushings (6-8 hours), crack repair may need welding. Alignment mandatory after. Polyurethane upgrades available but transmit more NVH.
Estimated cost: $1,200-2,400
Dashboard and Interior Delamination
Occasional · low severity
Symptoms: Dashboard surface becomes sticky or melted texture, Peeling vinyl on door panels and center console, Headliner sagging in rear, especially near rear window, Carpet edges pulling away from sill trim
Fix: UV and heat degrade the soft-touch plastics Infiniti used. Dashboard requires full removal and re-cover or replacement (10-14 hours for dash), headliner re-glue is 4-6 hours. Many owners live with it. Aftermarket dash covers are $200-400 DIY option.
Estimated cost: $800-2,500
AC Evaporator Core Leaks
Occasional · medium severity
Typical onset: 120,000-180,000 mi
Symptoms: AC blows warm intermittently, then stops cooling entirely, Oily residue or wet carpet on passenger side, System won't hold refrigerant charge, Musty smell from vents even after cabin filter change
Fix: Evaporator core corrodes and leaks refrigerant. Entire dash must come out for access—this is a 12-16 hour job. Includes evacuate/recharge, new expansion valve recommended while you're in there. Labor kills you on this one.
Estimated cost: $1,800-3,200
Power Steering Rack Leaks and Failure
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Power steering fluid leak at inner tie rod boots, Groaning noise when turning at low speed, Intermittent heavy steering effort, Fluid level drops repeatedly despite top-ups
Fix: Rack seals fail, sometimes rack develops internal scoring. Replacement rack required (used units often no better). 4-6 hours labor, includes alignment. Aftermarket racks available but quality is hit-or-miss—OE remanufactured preferred.
Estimated cost: $900-1,600
Brake Line Corrosion (Rust Belt)
Common · high severity
Symptoms: Visible rust perforation on steel brake lines along subframe, Soft or spongy brake pedal that doesn't improve with bleeding, Brake fluid leak visible at line connections or mid-run, Brake warning light with confirmed fluid loss
Fix: Steel brake lines rust through in salt states, especially along rear axle and front subframe runs. Complete brake line replacement (all four corners) is safest approach. 6-8 hours with pre-bent line kit, longer if custom flaring required. Inspection-failure item.
Estimated cost: $800-1,400
Takata Airbag Inflator Recall
Common · high severity
Symptoms: NHTSA recall notices for passenger airbag inflator, No symptoms until deployment—then risk of metal shrapnel, Airbag light may or may not illuminate
Fix: Two recalls for passenger-side Takata inflators. Dealer replacement is FREE but parts shortages meant years-long waits. Verify recall completion before purchase—check VIN at NHTSA.gov. Non-negotiable safety issue.
Estimated cost: $0
Owner tips
Change transaxle fluid every 30,000 mi with Nissan-spec fluid to延长 延长 prolong front diff life—many failures trace to neglected fluid
Inspect subframe bushings and mounting points annually after 80k mi; catch cracks early before they propagate
Use OE-quality parts for suspension—cheap aftermarket stuff fails quickly on this chassis weight
Rust-prone in salt states—undercoat treatment and frequent undercarriage washing pays off
Buy only if the front differential is quiet, subframe is solid, and all recalls are complete—budget $2-3k reserve for the inevitable diff or subframe work, otherwise it's a $500 parts-car waiting to happen.

AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE · 20V008000
2020-01-09 · EA15001
Nissan North America, Inc. (Nissan) is recalling certain 2001-2003 Maxima, 2002-2006 Sentra, 2002-2004 Pathfinder, 2007-2011 Versa Sedan and Versa Hatchback, 2001-2004 Infiniti I30 and I35, 2002-2003 Inifiniti QX4, 2003-2008 Infiniti FX35 and FX45 and 2006-2010 M35 and M45 vehicles. The vehicles are equipped with non-desiccated, frontal passenger air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Nissan will notify owners, and dealers will replace the front passenger air bag inflators with alternate desiccated inflators, free of charge. The recall began February 12, 2020. Owners may contact Nissan customer service at 888-737-9511 or Infiniti customer service at 888-810-3715.

ENGINE AND ENGINE COOLING · 03V455000
2003-11-17
ON CERTAIN PASSENGER VEHICLES, THE CIRCUIT BOARD FOR THE CRANK POSITION SENSOR OR CAM POSITION SENSOR MAY HAVE AN IMPROPER SOLDER JOINT DUE TO SOLDER DEFORMATION CAUSED BY HEAT STRESS ACCELERATED BY THE EXISTENCE OF FLUX RESIDUE DURING THE SOLDERING PROCESS.

Remedy: DEALERS WILL REPLACE THE CRANK POSITION SENSORS. CAMSHAFT POSITION SENSOR(S), AND IN SOME CASES, THE VARIABLE TIMING CONTROL SENSOR(S). VEHICLES INVOLVED IN A PREVIOUS RECALL CAMPAIGN, 01V357, ARE ALSO INCLUDED IN THIS NEW CAMPAIGN. THE REPLACEMENT SENSORS USED IN THAT CAMPAIGN ARE ALSO AFFECTED. OWNER NOTIFICATION BEGAN ON DECEMBER 22, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261 OR INFINITI AT 1-800-662-6200.
