- **Defective radio or power window switches**.
- **Modern diagnostics** (OBD-II) are not present in these models, making troubleshooting harder without a scan tool.
3. **Rust and Structural Concerns**
- Many **1990s minivans suffer from rust**, particularly in:- **Rockers (side panels near the wheels)**
- **Floor pans (especially in snowy climates)**
- **Hood and trunk areas**
- **Rust can compromise structural integrity**, leading to **frame rot** or **suspension issues** over time.
- **Undercoating is minimal or nonexistent**, accelerating rust in wet conditions.
4. **Safety and Modern Standards**
- **No modern safety features** (no ABS, no airbags in some models, no stability control).
- **Poor visibility** due to **small side windows** and **high roofline** (can be disorienting in traffic).
- **Noisy cabin** early models have **thin panels** that transmit road noise and engine vibration.
- **Poor fuel economy** the V6 gets around **16 18 MPG highway**, while the 4-cylinder is slightly better but still inefficient by today s standards.
