2017 Toyota Yaris 1.5L Petrol · DF17 LWD

The latest MOT test result for the 2017 Toyota Yaris shows a failure on 2026-06-17, with the primary defect being a serious fluid leak from the offside rear shock absorber, which is critical for roadworthiness and stability. Despite this failure, the vehicle has passed all previous MOT tests from 2020 to 2025, indicating that while the shock absorber issue is now present, it may not have been previously identified or addressed during those assessments. The recurring advisories on tyre sidewall damage or cracking from 2024 onwards suggest a consistent pattern of wear that could be exacerbated by prolonged standing or underinflation, though the severity of these advisories remains low-grade. This mixed history—with a recent failure but a stable maintenance trend prior—points to either a delayed or overlooked issue with the shock absorber, or a scenario where the vehicle has been driven intermittently, leading to the fluid leak becoming apparent only now. The recorded mileage of 9,121 miles for a vehicle aged nine years represents an annual usage rate of approximately 1,013 miles, which is notably low for its age. Such low mileage can result from infrequent use, long periods of stationary storage, or a lifestyle that avoids regular driving. However, low mileage does not inherently guarantee mechanical health, as components like tyres, brakes, and fluids can degrade over time due to exposure to environmental factors rather than wear from use. The absence of rapid mileage accumulation suggests that the vehicle has not been subjected to high-stress driving conditions, which could have accelerated wear on suspension, drivetrain, or exhaust systems. Nevertheless, the recent MOT failure highlights that the offside rear shock absorber has likely been compromised by prolonged exposure to road conditions, potentially leading to reduced suspension performance, uneven tyre wear, or even handling instability if left unaddressed. Given the recent MOT failure and the recurring tyre sidewall advisories, the prospective buyer should conduct a thorough inspection of the suspension system, particularly focusing on the offside rear shock absorber. During a test drive, listen for signs of excessive clunking or bouncing in the rear suspension, which may indicate fluid loss or internal damage. Also, check for uneven tyre wear patterns, particularly on the offside rear, which could correlate with suspension misalignment or poor shock performance. The tyre sidewall cracking advisories suggest that the tyres may be approaching their useful life, even if they appear to have sufficient tread depth. Inspect the tyres for signs of dry rot, delamination, or internal damage, as these can compromise safety and lead to blowouts. Additionally, verify that all tyres are properly inflated and that the vehicle’s wheel alignment is correct to mitigate further tyre wear. For the offside rear shock absorber, which failed the MOT due to a fluid leak, immediate replacement is strongly recommended to restore roadworthiness and prevent further damage. The fluid leak could lead to the shock absorber failing prematurely, resulting in reduced damping efficiency, which may cause the vehicle to feel harsh or unstable, especially during cornering or over bumps. If the shock absorber is beyond repair, consider replacing both the shock absorber and its associated lower control arm bushings to ensure symmetrical suspension performance. Beyond the suspension, the buyer should also check the brake system for signs of corrosion or binding calipers, particularly if the vehicle has been stationary for extended periods, as standing can cause brake discs to rust or seize. Finally, given the low mileage and clean previous MOT records, a comprehensive fluid check is advisable—including brake fluid, coolant, and transmission fluid—due to their susceptibility to degradation over time, even with minimal use. Ensure all fluids are topped up and free from contamination, and consider a service history review to confirm that routine maintenance, such as oil changes and fluid top-ups, has been conducted as recommended.
