Smart Fortwo (450) Problems by Year
The original Smart Fortwo (Type 450) revolutionized urban transport by offering a tiny, two-seat footprint that could literally be parked nose-in to the curb. Utilizing a Tridion safety cell and interchangeable plastic body panels, it became an instant icon in congested UK cities like London. However, its early automated manual gearbox is notoriously jerky, and the tiny turbocharged engines (600cc and 700cc) are fragile if not meticulously maintained. Many have succumbed to engine failure by 60,000 miles. It is strictly a city car, best suited to urban dwellers who prioritize parking ease over driving refinement and are prepared for specialist maintenance.

- ✓Prioritize cars with a documented engine rebuild if the mileage is over 60,000; the small turbo engines burn oil and lose compression quickly.
- ✓Pull back the carpets in both footwells to check for moisture; leaking windscreens frequently destroy the SAM unit (fuse box) underneath.
- ✓Check that all six spark plugs (two per cylinder) have been changed; garages often ignore the difficult-to-reach lower three.
- ✓Ensure the automated manual gearbox shifts through all gears; clutch actuators frequently seize and require adjustment or replacement.
- ✓Inspect the plastic body panels for cracking, particularly around the front bumper and wheel arches.
- ✓Look for heavy oil misting around the turbocharger and intercooler piping, indicating impending turbo failure.
