GarageCalc What the data says
Electrical system accounts for about 92% of this year's Mercedes-Benz EQB 250+ complaints. That is a strong concentration, the kind that usually points to a specific known issue rather than general wear.
The 2023 model year contributes 22 complaints (85%). No single model year dominates, so this looks like a line-wide pattern rather than one bad year.
Not enough 2025 complaints to compute a year-over-year trend (3 in the same window last year). Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Mercedes-Benz EQB 250+s are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.
