2022 Mercedes-Benz EQC 400 AMG Line Premium 4M Electricity · SO71 FTP

The EQC presents a mixed maintenance picture that has deteriorated noticeably in the most recent test cycle. The March 2026 pass at 38,844 miles carried three advisories, including both front inner brake discs flagged as worn, which marks a clear regression from the clean bill of health recorded in March 2025 at 30,639 miles. The trend is worsening rather than stable. Two advisories on inner brake discs suggest the vehicle has been driven hard or sat for extended periods, leading to surface corrosion and uneven wear patterns on discs that may not have been flagged as critical yet but will likely require attention within the next service interval. The nearside rear nail puncture advisory was minor but indicates the previous owner did not address it before the test, pointing to reactive rather than proactive upkeep. The mileage accumulation is broadly typical for a four-year-old vehicle, averaging just under 9,700 miles per year. The jump from 30,639 miles in March 2025 to 38,844 miles in March 2026 represents roughly 8,200 miles in twelve months, consistent with regular daily use rather than prolonged standing. No anomalous gaps or sudden spikes appear in the record, so there is no evidence of long-term garage storage or odometer irregularities. The annual test cycle itself is regular and unremarkable. A buyer should focus the physical inspection on the front braking system first. Inner disc wear advisories on both sides at the most recent test warrant measuring disc thickness and checking for lipping, uneven deposits, and binding calipers. The February 2025 failure flagged slight play in the nearside front suspension arm ball joint spring link, yet this did not reappear in the March 2025 or March 2026 tests, suggesting it was repaired or replaced. Still, a pushrod or pry-bar check on both front suspension ball joints and track rod ends is advisable, along with a close look at the subframe and lower arm bushes for cracking or corrosion. The two tyre-related advisories in the 2026 and 2025 failures, including exposed ply on the offside rear, indicate tyre condition has been a recurring weak point. Inspect all four sidewalls for age-related perishing, uneven wear, and correct specification fitment. Given the EQC's high-voltage architecture, also verify the condition of underbody panels and charge port seals, as water ingress around high-voltage components can be costly.
