2013-2026 Stellantis Aluminum Body Panel Corrosion

The Stellantis group has released Technical Service Bulletin (TSB) 31-001-25 REV. A, which addresses concerns about aluminum body panel corrosion. This bulletin, dated August 14, 2025, details the appearance of corrosion and bubbling on various exterior aluminum components across a wide range of 2013-2026 models from brands like Alfa Romeo, Chrysler, Dodge, Fiat, Jeep, and RAM. For owners of a 2023 Alfa Romeo Stelvio, or other affected vehicles, understanding the details of this TSB regarding aluminum body panel corrosion is important, despite its current status.

Symptoms of Aluminum Body Panel Corrosion

Owners of affected Stellantis vehicles, including the 2023 Alfa Romeo Stelvio, may observe specific signs of aluminum body panel corrosion. The primary symptom described in TSB 31-001-25 REV. A is "Aluminum corrosion or bubbling along the leading edge of hood, hinges or other exterior surface areas of the hinges, doors, fenders, swing gates or liftgates." This bubbling indicates a breakdown in the protective layers of the aluminum panels, leading to visible surface defects. These issues can affect the aesthetic appeal and potentially the long-term integrity of the vehicle's exterior.

Identified Cause

The underlying cause for this aluminum body panel corrosion is broadly identified as "Corrosion conditions." This suggests that environmental factors, such as exposure to moisture, road salts, or other corrosive agents, contribute to the degradation of the aluminum components. Aluminum, while generally resistant to rust, can still corrode under certain circumstances, often appearing as a white, powdery substance or bubbling beneath the paint.

Important Warnings for Owners

It is critical for owners to understand the current status of TSB 31-001-25 REV. A. The bulletin explicitly states, "This Information Only TSB has been put on hold until further notice." This means that while Stellantis acknowledges the issue of aluminum body panel corrosion, there is currently no authorized repair procedure or warranty claim process associated with this specific bulletin. Owners of vehicles like the 2023 Alfa Romeo Stelvio experiencing aluminum corrosion should not expect dealers to perform repairs under this TSB at this time. Furthermore, the policy for this bulletin is "Information Only," indicating it serves to inform technicians about the condition rather than provide a repair solution.

Superseded Bulletin Information

This current bulletin, TSB 31-001-25 REV. A, supersedes a previous Technical Service Bulletin, also numbered 31-001-25, which was issued on August 13, 2025. The superseded bulletin should be removed from dealer files. The revision highlights, marked with asterisks, indicate changes from the previous version, including the decision to suspend the information contained in the TSB until further notice. This suggests that Stellantis is re-evaluating the approach to addressing aluminum body panel corrosion.
