| 10192822 | SERVICE INFORMATION Replacement 5-speed rear wheel drive Automatic Transmission (A/T) assemblies and replacement control valves (valve bodies) now come with blank Transmission Control Modules (TCMs). Blank TCMs come without software and must be programmed (not reprogrammed) and then configured after they are installed. When ordering a replacement A/T or control valve, use the Infiniti electronic parts information systems to obtain the correct software program part number See this bulletin for further detail. |
| 10192806 | IF YOU CONFIRM A refrigerant leak at a refrigerant pipe/hose joint location, ACTIONS 1. Inspect the metal surfaces of the pipe/hose joint for damage or contamination. NOTE: Do not replace a refrigerant pipe, hose, or other A/C component if an o-ring seal will solve the leak incident, if it should occur. 2. If no damage is found to the joint metal surfaces, replace the O-ring seal. See this bulletin for further detail. |
| 10192802 | SERVICE INFORMATION Because of collision damage or other vehicle repair, a replacement "Certification Label" or "VIN Plate / Label" may be needed. These items may be available from Infiniti by request if certain criteria are met. This bulletinlists the criteria and provides an application form for such replacements. See this bulletin for further detail. |
| 10192728 | SERVICE INFORMATION The purpose of this bulletin is to give Infiniti dealers guidelines to help determine if windshield breakage is covered under warranty or is the customer?s responsibility. Nissan North America (NNA) is not responsible for damage to glass that is a result of objects striking or scratching the glass. 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 dealership PDI. |
| 10192718 | SERVICE INFORMATION The Intelligent Keys used on the various Infiniti vehicles may not be interchangeable between models and years. See this bulletin for further detail. |
| 10192693 | SERVICE INFORMATION Windshield "foreign material" that is on the surface of the glass in some cases can be cleaned off with a very particular type and grade of steel wool. * Most any foreign material on the surface of the Windshield can be cleaned off by using #0000 super fine steel wool. >The #0000 grade super fine steel wool can be found in most hardware stores. Please see this bulleitn for further details. |

| 10192616 | SERVICE INFORMATION The information in this bulletin is provided to help ensure correct diagnosis and repair of fluid leaks. All fluid leaks, when properly diagnosed, should be repaired (whether under warranty or customer pay) to ensure proper vehicle operation. However, certain normal operating conditions can be misdiagnosed as a leak requiring repair. Unnecessary repair or replacement of parts in connection with incorrectly diagnosed "leaks" can negatively impact customer satisfaction, be time consuming and costly, and if not performed correctly can lead to future repairs. See this b |

| 10192589 | SERVICE INFORMATION After ECM reprogramming, the Calibration Verification Number (CVN) needs to be automatically calculated prior to State emissions testing (also known as Inspection Maintainence, I/M, or SMOG testing depending upon location). Allowing the vehicle to idle for 22 minutes will allow for faster CVN calculation. It is recommended that customers utilize this method if the vehicle needs to be tested for emissions soon after ECM reprogramming. See this bulletin for further detail. |
| 10192533 | SERVICE INFORMATION NOTE - Failure to follow the procedures in this bulletin may result in the denial of a warranty claim.

The PGF protects the paint finish during vehicle handling, transportation and storage from harmful elements such as acid rain,iron particles, bird droppings, tree sap and other environmental contaminants.
