2012 Toyota IQ 1.0L Petrol · SW12 JOV

The most recent MOT test on the 2012 Toyota IQ was conducted on 2026-07-21 and resulted in a passing outcome, though it did not eliminate all prior concerns. The overall maintenance trend over the past four years shows a pattern of recurring issues rather than a consistent improvement, with several advisories and one major failure in 2024 related to the rear suspension coil spring fracture. The vehicle’s history also includes multiple exhaust and brake pipe corrosion advisories, along with structural corrosion that was noted but deemed not to compromise structural integrity. While the latest MOT did not flag any new major defects, the persistence of rust-related advisories and the prior coil spring failure suggest ongoing wear and potential long-term vulnerabilities in the suspension and exhaust systems. The vehicle’s recorded mileage of 95,575 miles at the time of this assessment represents a moderate annual usage rate of approximately 6,827 miles per year, which is typical for a 14-year-old car. This mileage level does not indicate excessive wear beyond what is expected for its age, but it also does not suggest minimal usage either. The gaps between MOT tests—particularly the two-year interval between 2024 and 2026—could imply periods of inactivity, which may have exacerbated corrosion issues, such as those observed in the exhaust pipes and brake components. Standing for prolonged periods can accelerate rust formation, especially in areas exposed to moisture, like the fuel tank heat shield and exhaust brackets. Additionally, the lack of recent service history beyond MOT compliance means consumables like brake fluid, coolant, and oil may have degraded over time, warranting attention to their condition. For a prospective buyer, the most critical areas to inspect during a physical examination are the rear suspension and exhaust system, given the recurring advisories and prior failures. Focus on the rear coil springs, which were fractured in 2024 and should be replaced if they exhibit signs of further deterioration, such as sagging, excessive play, or cracks. Listen for unusual noises from the rear axle during a test drive, particularly clunks or thumps that could indicate worn suspension bushes or binding components. The brake pipes, which were found to be corroded and greasy in multiple MOTs, should be thoroughly inspected for leaks, cracks, or structural compromise. If leaks are detected, the pipes may need replacement, and the brake system should be bled to ensure proper function. Additionally, the exhaust system’s mounting brackets, which were broken in 2026, should be checked for stability and signs of further wear, as a compromised bracket could lead to emissions-related issues or structural vibration problems. Beyond mechanical checks, the vehicle’s age and mileage warrant attention to several other potential concerns. Given the Toyota IQ’s design and the car’s age, inspect the tyres for signs of sidewall cracking or perishing, which can occur even at moderate mileages due to prolonged exposure to UV light and temperature fluctuations. The 12V battery should be tested for voltage output and overall health, as standing cars can suffer from parasitic drain or electrolyte degradation. Check the brake discs for corrosion, warping, or binding calipers, which may indicate standing corrosion or previous overheating events. Fluid levels should be topped up, and the coolant system should be inspected for leaks or sludge buildup, as coolant can degrade over time without regular servicing. Finally, verify the service book for any scheduled maintenance, such as timing belt replacement or suspension component inspections, which were not recorded in the MOT history but are critical for long-term reliability. If the vehicle has been in storage for extended periods, consider a thorough inspection by a qualified mechanic to address any latent issues before purchase.
