2019 Mercedes-Benz GLC 2.0L Petrol · DS19 NHE

The vehicle’s roadworthiness record demonstrates a concerning deterioration trend in critical suspension components, culminating in a recent failure just three weeks before its last pass. The May 2026 failure highlighted severe wear to both front suspension arm ball joints, a defect that had been flagged as minor play in the 2024 and 2023 tests. This suggests a pattern of deferred maintenance, as the ball joints—critical for wheel alignment and handling—were allowed to degrade over successive MOT cycles. The absence of defects in the most recent pass (May 2026) does not negate the urgency of addressing these issues, as they were clearly unresolved before the test. The tester’s failure to note corrective action implies the faults persisted despite the vehicle passing, raising questions about whether the suspension was inspected between tests or if the owner relied on temporary fixes. Mileage progression indicates moderate usage, averaging around 6,400 miles annually, which aligns with typical wear expectations for a seven-year-old vehicle. However, the gaps between tests reveal inconsistencies: the 2025 pass occurred at 39,213 miles, a span of nearly 4,500 miles since the 2024 test, while the 2026 failure and pass occurred within a 27-day window at 44,982 and 45,023 miles respectively. This clustering suggests the owner may have accelerated testing in anticipation of the suspension failure, rather than adhering to a regular maintenance schedule. The 2023 test also noted worn front tyres, implying a lack of proactive replacement despite the legal limit being approached—further evidence of neglect in consumable components. A buyer should prioritise an independent inspection of the front suspension, particularly the ball joints and associated camber arms, as the repeated failures indicate imminent failure risk. The near-side and off-side front suspension arms were flagged in three consecutive tests, with the 2026 failure confirming the condition had worsened significantly. Binding or excessive play in these components compromises steering stability and increases the risk of wheel detachment. Additionally, the 2023 tyre defects—perishing and edge wear—should prompt inspection of wheel alignment and potential subframe corrosion, as these issues often correlate with suspension misalignment. The windscreen wiper blade failure in 2025 is a minor consumable but worth verifying, as worn blades impair visibility in adverse conditions. Structural integrity checks, including underbody corrosion around the wheel arches and suspension mounts, are advisable given the vehicle’s age and mileage.
