All 2 Known Issues
On the 1990-2001 Chevrolet Metro, the Metro is extremely rust-prone due to thin body panels and inadequate corrosion protection. The front subframe, rocker panels, and rear quarter panels rot through, sometimes to the point of structural failure. In salt-belt states, Metros can become structurally unsafe within 10-15 years.
Common Symptoms
- Visible rust holes in body panels
- Soft or spongy floor pan
- Clunking from front end over bumps
- Subframe visibly corroded
- Failed safety inspection
How to Fix
Inspect the subframe mounting points and rocker panels carefully before investing in any other repairs. If the subframe mounts are compromised, the vehicle is unsafe. Minor rust can be cut out and patched with welded-in repair panels. Apply rust converter and undercoating to slow progression. Many Metros are scrapped due to rust rather than mechanical failure.

On the 1990-2001 Chevrolet Metro, the small Suzuki-sourced 3-cylinder and 4-cylinder engines develop head gasket failures, particularly when the cooling system is neglected. The aluminum cylinder head warps from overheating episodes, and once warped, even a new gasket will fail again without head resurfacing. The 1.0L 3-cylinder is especially vulnerable.
Common Symptoms
- White exhaust smoke
- Overheating
- Coolant loss
- Bubbles in coolant reservoir
- Rough idle
How to Fix
Replace the head gasket and have the cylinder head inspected for warpage and resurfaced if needed. Replace the thermostat and water pump at the same time. Use the correct torque specifications and tightening sequence. The small engine makes this a relatively quick job compared to larger vehicles.
