Mevion Medical Systems, Inc. Recall Insight
Mevion Medical Systems, Inc. appears on 14 federal recall records indexed by PlainRecalls, out of 101,704 total recalls tracked across the FDA, CPSC, and NHTSA. That represents approximately 0.014% of the federal archive, a data point that is only interpretable alongside production volume, product mix, and decades of operation, because a high recall count alone does not establish fault. Large, diversified firms that sell tens of millions of units across many categories will mechanically accumulate more recall records than small manufacturers, even when their defect rates per unit shipped are comparable or lower. The most recent action on this firm is dated Apr 6, 2022, which is the anchor point for assessing whether enforcement is currently active or historical.
On this page of 14 entries, severity tagging shows 0 critical, 14 moderate, and 0 lower-severity recalls. Affected-unit counts are disclosed on 14 of 14 entries, unit-count disclosure is more common on CPSC and NHTSA actions and less common on FDA drug/device recalls, where lot numbers and distribution scope substitute for absolute totals. The records on this page span 1 distinct product categories, with issuing agencies dominated by FDA Devices (14). The date window on this page runs from Apr 2, 2014 to Apr 6, 2022.
Manufacturer-level browsing is useful when monitoring a single firm for patterns, whether recalls cluster around one product family (suggesting a specific design or supplier issue) or scatter across the firm's entire catalog (which can indicate systemic quality-control problems or deliberate regulator attention). Clicking into each recall reveals the specific hazard, remedy, and distribution scope that together determine whether a consumer is actually at risk. For decisions that depend on being current, deciding whether a product in your home is safe, whether to return a gift, or whether to accept a replacement, always verify the recall number on the issuing agency's site, because federal agencies amend, terminate, and re-scope recalls over time and only the agency's live record reflects the current legal status. This page aggregates what agencies have published publicly and is intended for consumer awareness and research.
