Chevrolet Express 1500 issues with rear end, brake system, transmission, and electrical plug needing diagnosis on Chevrolet Express 1500

Some Chevrolet Express 1500 owners report experiencing significant rear end issues, including severe rust on rear leaf spring hangers that can lead to safety hazards such as the rear axle assembly detaching or the frame breaking. Additionally, some owners have noted brake system problems, such as damaged brake hoses that reduce rear brake effectiveness, which was part of a recall for the 2011 model. Other brake-related concerns include brake fluid leaks, deformed rotors, and premature wear of brake pads. Transmission concerns have also been reported, particularly with the 2022-2023 models, which faced a safety recall due to transmission control module issues causing harsh shifting, reduced power, unintended deceleration, and rear wheel lockups. Furthermore, intermittent harsh shifting has been noted in the 4L60E transmission, potentially linked to wiring harness issues affecting the TCC solenoid and pressure control solenoid. Lastly, electrical problems impacting the console or warning lights may require diagnosis at a dealership under a Technical Service Bulletin. It is essential for owners to address these issues promptly to ensure the safety and performance of their Chevrolet Express 1500.
