2003 Chevrolet Express 3500 problems
The Chevrolet Express (also known as the GMC Savana) is a series of full-size vans produced by General Motors since 1996. The successor to the Chevrolet G-series van, the Express is produced in passenger and cargo variants. Alongside the standard van body, the line is offered as a cutaway van chassis; the latter vehicle is a chassis cab variant developed for commercial-grade applications, including ambulances, buses, motorhomes, and small trucks.
In production for a single generation since 1995, over 2.5 million examples of the Express and the Savana have been produced. One of the longest-produced designs in American automotive history, the Express/Savana are rivaled only by the Jeep Wagoneer and Dodge Ram Van for longevity.
Since 1995, General Motors has assembled the Express and Savana at its Wentzville Assembly facility (Wentzville, Missouri). Also, since 2017, GM has sourced commercial cutaway-chassis production from Navistar through its Springfield Assembly Plant (Springfield, Ohio).

Common 2003 Chevrolet Express 3500 problems
Based on the complaints from owners of the Chevrolet Express 3500 2003, several common problems have been reported:
- Hydraulic Brake Booster Pressure Accumulator Crack: A recall was issued for certain Chevrolet Express 3500 vehicles due to a crack in the hydraulic brake booster pressure accumulator, which could separate from the hydro-boost assembly during normal operation. This issue could lead to a loss of vehicle control, increasing the risk of a crash. Owners were advised to contact Chevrolet for a replacement of the hydro-boost assembly.
- Wheel Bearing Assembly Retaining Nut: Some vans were built without a wheel bearing assembly retaining nut, potentially leading to bearing separation and disabling the ABS system. This could result in a grinding noise, decreased vehicle speed, and steering pulling in the direction of the affected brake assembly, posing a risk of a crash. Owners were instructed to have the wheel bearing assembly inspected and replaced if necessary.
- Safety Belt Buckle Malfunction: In certain vans with a gross vehicle weight of less than 8,500 pounds, the front safety belt buckles may not release after a crash or could cause the buckle to unlatch during a crash, increasing the risk of personal injury. Dealers were required to replace the front driver and passenger side safety belt buckles to address this safety concern.
These issues highlight the importance of addressing safety recalls promptly and conducting thorough inspections to ensure the proper functioning of critical components in the Chevrolet Express 3500 2003 model.
