GEN1 (2005–2013) — Engine options included the 1.1L Petrol. We track 5 known issues on this generation, with 4 classified as significant. The most significant concern is Power steering fluid leak and system malfunction (£300–£600 to address).
The power steering system on the Proton Savvy suffers from exceptionally high failure rates, with MOT data showing 208 times the national fleet average for power steering fluid leaks and system malfunctions. The pump, high-pressure lines, and reservoir are all prone to failure. This affects the majority of cars in the 20,000-80,000 mile range and represents the most significant reliability issue with this model.
Complete power steering failure makes the car extremely difficult to steer, particularly at low speeds and when parking. This creates a significant safety hazard. Pump replacement typically costs £300-600, while steering rack replacement can cost £400-800 plus alignment.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
Wheel bearings on the Proton Savvy fail at 41 times the national fleet average, with the highest failure rate occurring between 20,000-40,000 miles. This exceptionally early failure rate suggests inadequate bearing specification or poor quality control. The problem affects all four corners but front bearings typically fail first due to steering loads.
A collapsed wheel bearing can cause the wheel to seize or detach, creating an extremely dangerous situation. Early replacement is essential once noise or play is detected. Individual bearing replacement typically costs £150-300 per corner including labour.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The Proton Savvy exhibits severe brake problems with binding brakes occurring at 26 times the fleet average and brake imbalance at 23 times the average. Brake calipers seize frequently, causing uneven braking and accelerated disc and pad wear. This affects cars from very low mileage, suggesting manufacturing quality issues with the brake components.
Binding brakes cause rapid pad and disc wear, poor fuel economy, and dangerous braking imbalance that can cause loss of control. Complete brake overhaul may be needed, costing £400-800 for front and rear systems.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
Coil springs on the Proton Savvy fail at 17 times the national fleet average, with failures occurring from very low mileage. This suggests inadequate spring specification or metallurgy issues. Spring fracture can occur suddenly and creates a dangerous situation where the car loses ride height and handling stability.
A broken coil spring creates dangerous handling characteristics and can damage other suspension components or tyres. The car should not be driven with a fractured spring. Spring replacement typically costs £150-250 per pair including labour and alignment check.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Suspension components on the Proton Savvy deteriorate rapidly, with joint dust covers failing at 19 times the fleet average and suspension components suffering damage at 17 times the average. Ball joint and CV joint dust covers split prematurely, allowing dirt ingress and accelerating wear. The suspension bushes and components appear to be of poor quality specification.
Split dust covers lead to premature joint wear and eventual failure. Worn suspension bushes cause poor handling, tyre wear, and MOT failure. Individual component replacement ranges from £50-200 per item, but multiple components often need attention simultaneously.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
