2018 Mercedes-Benz GLA 1.6L Petrol · TC02 ACE

The most recent MOT test on the 2018 Mercedes-Benz GLA, conducted on 2025-09-26, resulted in a passing outcome, though it included a single advisory regarding an offside rear tyre nail. This follows a pattern of consistent MOT results from 2023 onwards, with no major failures or repeated advisories, suggesting a generally stable maintenance record. However, the vehicle’s failure in 2024 highlights critical issues—specifically, exposed tyre cords on the nearside rear tyre and sidewall perishing on both front and rear tyres—indicating severe wear beyond the legal limits and a failure to address tyre degradation promptly. These failures underscore a need for caution, as tyre safety is paramount for roadworthiness and accident prevention, particularly given the potential for sudden blowouts or reduced traction in adverse conditions. The vehicle’s recorded mileage of 53,832 miles over approximately eight years reflects an average annual usage of around 6,729 miles, which is within the expected range for a car of this age and class. While lower mileage could imply periods of inactivity or lighter use, higher mileage would typically accelerate wear on consumables like tyres, brakes, suspension components, and fluids. The absence of significant mileage spikes suggests steady operation, but the 2024 MOT failures—particularly the exposed tyre cords—point to either aggressive driving, poor tyre management, or a lack of regular tyre rotation and balancing. Tyres are the most critical safety component, and the exposed cords indicate that the vehicle’s tyres have reached a critical state where they are no longer capable of providing adequate grip, necessitating immediate replacement to avoid failure during use. For the prospective buyer, the most urgent concern is the tyre condition, as the exposed cords and sidewall perishing from the 2024 MOT failure are highly dangerous. On inspection, check the tyre tread depth with a legal tread depth gauge or the UK’s 1.6mm minimum requirement—any exposed cords or visible perishing must be replaced immediately, regardless of remaining tread. Before proceeding with purchase, verify the tyre brand, model, and load index to ensure compatibility with the vehicle’s specifications. During a test drive, listen for unusual noises such as a grinding or scraping sound from the rear, which could indicate tyre separation or a blowout risk. Additionally, examine the vehicle’s suspension for uneven tyre wear, which may suggest misalignment or worn suspension components, though this is less critical than the tyre failures but should be noted for further investigation. Beyond tyres, given the vehicle’s age and moderate mileage, the buyer should conduct a thorough inspection of the engine bay and undercarriage for signs of fluid leaks, particularly from the oil, coolant, and brake systems. Check the 12-volt battery for corrosion on terminals and a healthy charge, as standing vehicles can lead to battery degradation over time. Inspect the brake system for corrosion on discs and calipers, especially near the rear where standing can cause rust buildup, which may lead to binding or reduced braking performance. Fluid levels should be checked for any signs of degradation or contamination, with brake fluid and coolant ideally serviced every two years or 60,000 miles, whichever comes first, due to their susceptibility to moisture absorption and performance loss. Lastly, verify that the service history book is complete, particularly for oil changes, filter replacements, and suspension component inspections, as these are critical for maintaining the vehicle’s structural integrity and safety.
