- Solution: Replacement of timing belt, tensioners, and idler pulleys. This is a critical maintenance item.
- Cost: $700 - $1200
Transmission
5-Speed Manual
Clutch Wear
- Symptoms: Slipping clutch, difficulty engaging gears, stiff clutch pedal.
- Solution: Replacement of clutch kit (disc, pressure plate, release bearing).
- Cost: $600 - $1000
Gearbox Synchromesh Issues
- Symptoms: Grinding when shifting gears, difficulty selecting specific gears.
- Solution: Rebuild of the gearbox or replacement of synchromesh rings.
- Cost: $1000 - $2000
6-Speed Manual
Clutch Wear
- Symptoms: Slipping clutch, difficulty engaging gears, stiff clutch pedal.
- Solution: Replacement of clutch kit (disc, pressure plate, release bearing).
- Cost: $700 - $1100
Gearbox Bearing Noise
- Symptoms: Whining or rumbling noise from the gearbox, especially at speed or when accelerating/decelerating.
- Solution: Rebuild of the gearbox with replacement of worn bearings.
- Cost: $1200 - $2200
Suspension
Standard Chassis
Worn Bushings
- Symptoms: Clunking noises over bumps, vague steering feel, uneven tire wear.
- Solution: Replacement of worn suspension bushings (e.g., control arm, anti-roll bar).
- Cost: $400 - $800
Shock Absorber Failure
- Symptoms: Bouncy ride, poor handling, visible leaks from shock bodies.
- Solution: Replacement of front or rear shock absorbers.
- Cost: $500 - $900
Electrical
General Electrics
Window Regulator Failure
- Symptoms: Power windows not operating, slow window movement, grinding noise from the door.
- Solution: Replacement of the window regulator mechanism.
- Cost: $200 - $400
Central Locking Issues
- Symptoms: Doors not locking/unlocking consistently, individual door lock actuators failing.
- Solution: Diagnosis and replacement of faulty door lock actuators or control modules.
- Cost: $150 - $350
ABS/VDC Sensor Failures
- Symptoms: ABS and VDC warning lights illuminated on the dashboard, loss of ABS/traction control functionality.
- Solution: Replacement of faulty ABS wheel speed sensors or VDC module.
- Cost: $250 - $500
Exterior
Body Panels & Trim
Rust
- Symptoms: Corrosion typically found on wheel arches, sills, and around the rear window.
- Solution: Rust removal and repair, repainting. Prevention through regular washing and underbody protection.
- Cost: $500 - $2000+
Convertible Roof Mechanism (GTV Spider)
- Symptoms: Slow operation, leaks, motor failure, fabric wear.
- Solution: Lubrication, seal replacement, motor repair/replacement, or fabric replacement.
- Cost: $400 - $1500
Interior
Cabin Components
HVAC Blower Motor Resistor
- Symptoms: Fan only works on highest setting, or not at all.
- Solution: Replacement of the blower motor resistor.
- Cost: $100 - $200
Seat Wear
- Symptoms: Bolster wear on leather seats, stitching coming undone.
- Solution: Professional repair or replacement of seat covers/panels.
- Cost: $300 - $800
Summary Verdict
The 2003 Alfa Romeo GTV is a desirable sports coupe with a characterful driving experience. Its reliability is a mixed bag; while the core mechanicals can be robust, specific components are known to require attention. The Twin Spark engines are prone to camshaft and ignition issues, while the V6 Busso engines require diligent timing belt maintenance. Manual transmissions can develop synchromesh problems or require clutch replacements. Suspension bushings and electrical gremlins, particularly with window regulators and central locking, are also common. Rust can be a significant concern, especially on older examples. Despite these potential issues, with diligent maintenance and prompt attention to developing problems, the GTV can remain a rewarding and stylish car to own.
