Classification: Reference: Date: BT09-053J ITB09-039J February 27, 2023 WINDSHIELD CRACKING This bulletin has been amended. See AMENDMENT HISTORY on the last page. Please discard previous versions of this bulletin. APPLIED VEHICLES: All Infiniti SERVICE INFORMATION The purpose of this bulletin is to give Infiniti retailers guidelines to help determine if windshield breakage or damage is covered under warranty or is the client’s responsibility. Nissan North America (NNA) is not responsible for damage to glass that is a result of objects striking or scratching the glass, including damage caused by the installation of aftermarket window tinting. However, NNA is responsible for manufacturing issues such as distorted glass and cracks that are due to improper installation or damage to the glass during vehicle assembly. NNA typically does not find any type of cracks in the windshield due to stress after the pre-delivery inspection (PDI). Glass damage can be categorized in three general areas: 1. Cracks due to objects striking the glass (page 2). 2. Cracks due to scratch in glass surface (page 5). 3. Distortion or cracks due to manufacturing fault (page 7). Part Return Process Reminder: Prior to removal, retailers must take at least two digital photographs of the damaged area. Retailers are required to mark glass and other components returned that have “visible issues” using masking tape or appropriate means (grease pen, etc.) to identify and highlight the area damaged. HINT: The claim may be debited if the part is not marked properly and/or missing the required digital photographs. Refer to the Glass Part Return section of the Infiniti Assurance Products Reference Manual (APRM) for complete glass return details. Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this applies to your vehicle. 1/9 1) HOW TO DETERMINE IF GLASS DAMAGE IS DUE TO OBJECTS STRIKING THE GLASS Cracks from Objects Striking the Glass Most windshield damage that occurs due to impact is easily identified as shown below: Cone shaped break (A, B, C) Crush mark (D, E1, F) Star shape crack (C, D, E2, F) A B C D F E1 E2 Cracks can spread and become larger from the original strike point or crush mark due to: Thermal stresses caused by temperature fluctuation. External physical stresses, such as hand touch, wind force, or vehicle vibration during driving (pot holes). A lead, or crack from one of the star cracked impact points can run to the edge of the glass and appear to be a low stress crack starting from the glass outside edge. 2/9 ITB09-039J Single Crack Beginning or Ending at the Edge of the Glass Single cracks must be inspected along the entire crack for impact marks. If any impact mark is found anywhere along the crack, it indicates the damage occurred from an object striking the windshield. This is not covered under warranty. The tip of a ball point pen can be run along the crack in the windshield to find the impact point. A magnifying glass (10X magnification) may be necessary to identify impact marks that may be less than 1 mm in diameter. HINT: A lead, or crack from an impact point can run to the edge of the glass and appear to be a low stress crack starting from the glass outside edge. Impact Mark Single crack with no impact mark: Warranty Single crack with impact mark: Not Warranty Compound Crack Beginning or Ending at the Edge of the Glass This type of crack is always caused by impact to the glass. The point of impact is located where the crack “branches out”. Impact Mark Compound crack: Not Warranty 3/9 ITB09-039J Cracks That Are Only in the Middle of the Glass This type of crack does not begin or end at the edge of the glass. These cracks are always caused by an impact to the glass and are not covered under warranty. Cracks not reaching edge: Not Warranty 4/9 ITB09-039J 2) HOW TO DETERMINE IF GLASS DAMAGE IS DUE TO A SCRATCH IN THE GLASS SURFACE Cracks from a Scratch in the Glass Surface Glass is produced by fusing together various raw materials such as silica, soda ash, and limestone, and has hardness of 5 to 6 on the Mohs scale (for reference, a diamond has a hardness of 10 on the same scale). Since earth and sand can contain substances harder than that of glass, glass can be easily scratched by: Fine sand particles. Hard metal. Rubbing action of contaminated wiper rubbers, or sand particles caught between the wiper and the glass, especially when operating the wipers in a dry condition. A magnifying glass (10X magnification) may be necessary to identify wiper scratches as a start point of cracks in the glass. Inspect the wiper paths (may be a single scratch of a group of scratches). Small scratches can cause a small rupture in the outer glass surface, which can lead to a crack from thermal conditions, vehicle vibration during driving, or wind pressure. Wiper position Wiper position Scratch from sand/stone: Not Warranty 5/9 ITB09-039J A magnifying glass (10X magnification) may be necessary to identify metal object scratches as a start point of cracks in the glass. Scratches can occur from metal objects such as keys and metal buttons. These scratches are typically sharp and can be found anywhere on the glass surface. Thoroughly examine the entire length of the crack to identify any scratch as a start point. Small scratches can cause a small rupture in the outer glass surface, which can lead to a crack from thermal conditions, vehicle vibration during driving, or wind pressure. Scratch from metal objects: Not Warranty A magnifying glass (10X magnification) may be necessary to identify scratches caused by a contaminated towel as a start point of cracks in the glass. Scratches can occur from wiping the glass with a towel that has sand particles or dirt on it. These scratches are typically long and have several scratches concentrated together. These scratches can be found anywhere on the glass surface. Thoroughly examine the entire length of the crack to identify any scratch as a start point for cracks in the glass. Magnified 42x Scratch from dirty towel/cloth: Not Warranty 6/9 ITB09-039J 3) HOW TO DETERMINE IF GLASS HAS DISTORTION OR CRACKS DUE TO MANUFACTURING ISSUE Distortion or Cracks Due to Manufacturing Issue Open bubble – Warranty Surface blister - Warranty Adhesion chip – Warranty (Can occur from a manufacturing issue such as adhesion of molding to the glass surface along the glass edge.) Surface blister – Warranty 7/9 ITB09-039J CLAIMS INFORMATION For manufacturing issue claims only: Submit a Primary Failed Part (PP) line claim using the following claims coding: DESCRIPTION PFP OP CODE SYM DIA FRT RPL Windshield (1) UG10AA FD 03 (2) (1) Reference the Electronic Parts Catalog (EPC) and use the applicable Windshield P/N as the PFP. (2) Reference the current Infiniti Warranty Flat Rate Manual and use the indicated FRT. HINT: Refer to the Glass Part Return section of the Infiniti Assurance Products Reference Manual (APRM) for complete glass return details. Part Return Process Reminder: Retailers are required to take at least two digital photographs that clearly identify the alleged glass defect prior to removing the glass from the vehicle. Digital photographs must be kept in retailer records. Retailers are required to mark glass and other components returned that have “visible issues” using masking tape or appropriate means (grease pen, etc.) to identify and highlight the area damaged. The new glass warranty form must be completed and digital photograph files attached through ASIST for: 1. Over DCAL Warranty Call Center pre-authorization 2. Glass Part Return requests The claim will be subject to a claim debit if the part is not marked properly and/or missing the required digital photographs (via ASIST) to support identification of a warrantable defect. Glass warranty form is found here 8/9 ITB09-039J AMENDMENT HISTORY PUBLISHED DATE REFERENCE DESCRIPTION August 25, 2009 ITB09-039 Original bulletin published March 8, 2013 ITB09-039A Latest models and model years applied April 28, 2015 ITB09-039B Latest models and model years applied, and pages 1 and 3 revised January 28, 2016 ITB09-039C Latest models and model years applied, and the “Part Return Process Reminder” section revised February 21, 2017 ITB09-039D Latest models and model years applied, aftermarket window tinting statement added, and APRM reference on pages 1 and 8 revised November 29, 2017 ITB09-039E Latest models and model years applied, and warranty information on pages 1 and 8 revised April 9, 2018 ITB09-039F Latest models and model years applied May 15, 2019 ITB09-039G Latest models and model years applied, and APRM reference on pages 1 and 8 revised May 10, 2021 ITB09-039H Latest models and model years applied, and APRM reference on pages 1 and 8 revised February 17, 2022 ITB09-039I Publication date revised to include the latest models and model years February 27, 2023 ITB09-039J Publication date revised to include the latest models and model years, and APRM reference on pages 1 and 8 revised 9/9 ITB09-039J
