What is the Issue?
Stellantis has issued a Quality Inspection Request (QIR), identified as communication ID 111406, concerning specific cylinder head cover bolts. This request focuses on part number 04893799AJ, which is used in various Jeep, RAM, and Dodge vehicles. The purpose of this communication is to ensure that only properly manufactured bolts are used in service and assembly. The communication highlights a critical distinction between "good" and "suspect" parts to prevent potential issues related to incorrect components. This quality check is vital for maintaining the integrity of engine components, including those found in models like the Jeep Wrangler.
Identifying Suspect Parts
The core of this Quality Inspection Request is the visual identification of the cylinder head cover bolts. Dealerships are instructed to differentiate between two types of bolts for part number 04893799AJ.
- Good Parts: These are described as "Bolts with flat ended flange". The PDF includes an image clearly showing a bolt with a flat, even flange at its base. These bolts are considered correct and can be used for sales and service.
- Suspect Parts: These are identified as "Bolts with chamfer to the flange". The accompanying image in the communication illustrates a bolt where the flange has a noticeable chamfer or bevel. These suspect bolts must be quarantined immediately.
This visual distinction is crucial for technicians to correctly identify and separate the parts. The presence of a chamfer on the flange indicates a manufacturing deviation that makes the bolt unsuitable for use.
Dealer Actions and Deadlines
Dealerships that have been identified as having stock on hand or parts in transit for part number 04893799AJ are required to take specific actions. The manufacturer communication ID 111406 outlines the following steps:
- Inventory Check: Dealerships must thoroughly check their current inventory and any incoming shipments for cylinder head cover bolts with part number 04893799AJ.
- Quarantine Suspect Parts: Any bolts identified as "suspect part- Bolts with chamfer to the flange" must be immediately quarantined to prevent their use.
- Return Procedure: All suspect parts must be returned to the designated facing depot. The communication specifies using "Return Code 02" for this process.
- Return Deadline: The deadline for returning these suspect parts is "29th April 2026". Dealerships are advised to complete the return process before this date.
- New Orders: For replacement parts, dealerships are instructed to "place new orders" to ensure they receive the correct "Bolts with flat ended flange".
- Open Orders: The communication also explicitly states, "Return any open orders in process too," indicating that even parts currently on order that might be suspect should be addressed.
- Support: For any questions regarding the return process, dealerships can contact "[email protected]".
Why This Matters for Owners
While this communication is primarily directed at dealerships, it has direct implications for owners of affected vehicles, including the Jeep Wrangler. This Quality Inspection Request ensures that only high-quality, correctly manufactured components are used in the maintenance and repair of their vehicles. Using the proper cylinder head cover bolts with a flat-ended flange is essential for the long-term reliability and performance of the engine. It helps prevent potential issues that could arise from using an incorrectly manufactured bolt, thereby safeguarding the vehicle's integrity and the owner's peace of mind.
Important Warnings for Dealerships
Dealerships must adhere strictly to the instructions provided in this Quality Inspection Request (ID 111406) to avoid using incorrect parts.
- Do NOT use suspect parts: Bolts identified as having a "chamfer to the flange" must not be used for sales or service. They must be quarantined and returned.
- Return all open orders: It is critical to "Return any open orders in process too" that may contain suspect part number 04893799AJ to prevent them from entering the usable inventory.
- Adhere to the deadline: All suspect parts must be returned using "Return Code 02" by "29th April 2026". Failure to do so may result in continued inventory of non-conforming parts.
