2002-2004 Infiniti I35 Grille: A Buyer's Guide to Damage, Fitment, and Replacement
This guide covers common issues like peeling chrome and broken tabs, and provides a complete walkthrough for buying a used OEM grille for your 2002-2004 Infiniti I35.
- The most critical step when buying a used grille is to inspect all mounting tabs on the back for damage; broken tabs will prevent a secure fit.
- The OEM part numbers are 62310-5Y800 and 62310-5Y80A, which are interchangeable and fit all 2002-2004 I35 models.
- Peeling and bubbling of the chrome finish is the most common failure, a cosmetic issue that is difficult to repair.
- Replacement is a simple DIY task that can be completed in under an hour with basic tools.
Symptoms of a Damaged Grille
Since the grille is a cosmetic and passive-protection part, symptoms of failure are almost always visual. You won't see a check engine light, but you will notice physical issues.
- Cosmetic Flaws: The most common issue is deterioration of the chrome finish. Look for peeling, bubbling, flaking, or a hazy, milky appearance under the clear coat. This is often caused by age, UV exposure, and harsh cleaning chemicals.
- Cracks and Breaks: Physical impacts from road debris, parking lot bumps, or minor collisions can cause the plastic to crack or shatter. Pay close attention to the thin horizontal slats and the main frame.
- Loose Fitment: If the grille feels loose, rattles, or has noticeable gaps between it and the hood or bumper, one or more mounting tabs are likely broken. These tabs are critical for a secure fit.
- Missing Emblem: The Infiniti emblem is often a separate piece and can be stolen or fall off. Many aftermarket and even some used grilles are sold without the emblem.
Pro Tip: A forum user on a G35 forum noted that their dealer replaced a peeling chrome center cap on an I35 under warranty, even when the car was past 12,000 miles. While these vehicles are now well out of warranty, this indicates that chrome peeling was a known issue even when the cars were newer.
Buying a Used 2002-2004 Infiniti I35 Grille: What to Inspect
A used OEM grille is often the best value, offering factory fit and quality at a lower price than a new part. However, careful inspection is crucial before buying.
- Check All Mounting Tabs: This is the most important inspection point. Flip the grille over and carefully examine every single mounting tab and clip location. These are frequently broken during removal or from minor impacts. A grille with even one broken tab may not mount securely, leading to rattling or a poor fit.
- Inspect the Chrome Finish: Look at the chrome from multiple angles under good light. Check for the common signs of peeling, bubbling, or hazing. While minor cosmetic wear is expected on a used part, deep peeling can't be easily repaired and will detract from your car's appearance.
- Look for Hidden Cracks: Flex the grille slightly to reveal any hairline cracks, especially around the screw holes and where the slats meet the frame. What looks like a small crack can quickly spread once installed on the vehicle.
- Verify the Emblem Status: Confirm whether the grille includes the Infiniti emblem. Many used grilles are sold without it, and purchasing one separately adds to the total cost.
- Confirm Part Numbers: The original part numbers are 62310-5Y800, which was later superseded by 62310-5Y80A. Both parts are identical in fit and appearance for all 2002, 2003, and 2004 I35 models.
Replacement Guide
Replacing the grille on a 2002-2004 Infiniti I35 is a straightforward job that most DIYers can complete with basic hand tools. The process typically involves removing several clips and possibly a few screws at the top of the grille, which allows it to be tilted forward and lifted out. In some cases, removing the front bumper cover may provide easier access but is not always necessary. The entire job can usually be done in under an hour.
Known Issues, Recalls, and TSBs
There are no recalls or Technical Service Bulletins (TSBs) specifically for the grille of the 2002-2004 Infiniti I35. The primary known issue, based on owner forums, is the cosmetic peeling and degradation of the chrome finish over time.
Important Recall Note: While the grille itself has no recalls, all 2002-2004 Infiniti I35 models are subject to major recalls for faulty Takata airbag inflators, which could rupture and cause serious injury or death. It is critical to verify that this safety recall has been performed on your vehicle by checking the VIN on the NHTSA website or with an Infiniti dealer.

Frequently Asked Questions (FAQ)
Is it difficult to replace the I35 grille myself?
No, it is considered an easy DIY job. Basic hand tools are all that's required to remove the upper clips and fasteners. The replacement can typically be done in less than an hour.
Will a grille from a Nissan Maxima fit my Infiniti I35?
No. While the Infiniti I35 is based on the Nissan Maxima platform, the front fascia, including the grille, headlights, and bumper, are unique. You must use a grille specifically designed for the 2002-2004 Infiniti I35.
Do aftermarket grilles come with the Infiniti emblem?
Almost never. Due to trademark laws, aftermarket grilles are sold with a provision for the emblem, but you will need to purchase the emblem separately or transfer it from your old grille.
Can I just repair the peeling chrome on my original grille?
Repairing peeling chrome is very difficult and often not cost-effective. The process would involve stripping the old chrome, which is a specialized task. For most owners, replacing the grille with a good-condition used or new aftermarket part is the more practical solution.
