After a serious machine injury, the first explanation offered is almost always the worker. He reached in. She bypassed the guard. He was moving too fast. Michigan product liability law exists in large part because engineers have understood for generations that machines are operated by human beings: tired ones, rushed ones, ones doing exactly what production quotas demand. Machines are supposed to be designed around foreseeable human behavior, and when they are not, the law can hold the manufacturer responsible.
Product claims against machinery manufacturers reach compensation that workers’ comp never provides, and they are among the most technically demanding cases in injury law, defended by manufacturers with decades of practice. The work injury lawyers at Vahdat Weisman Law build defective machinery cases for injured workers across Michigan, alongside the comp benefits that keep a family going in the meantime.

Michigan law recognizes defects in design, in manufacture, and in warnings. Design cases are the heart of machinery litigation: the press that cycled without a two-hand control, the conveyor with an unguarded pinch point, the lift with no interlock. Under MCL 600.2946, a design claim turns on whether a practical and technically feasible safer alternative existed when the machine was made, one that would have prevented the harm without significantly impairing the machine’s usefulness or creating equal dangers. The date matters: Michigan measures design against what was known and feasible at the time of manufacture, not at the time of your injury, and Michigan law imposes no general duty to recall or retrofit old machines when technology later improves. Where ANSI standards and the machine-safety literature specified the fix before the machine was built, feasibility stops being theoretical, and proving that alignment is engineering work we resource properly.
Manufacturing defect cases involve the machine built wrong: the weld that failed, the hydraulic component that ruptured. Warning cases involve hazards the manufacturer understood, and the operator was never adequately told. Serious machinery cases often plead more than one theory, and the engineering investigation shows which the evidence supports.
Manufacturers defend these cases vigorously, arguing the design was sound, the standards were met, and someone else caused the harm. Michigan gives their most common arguments specific legal shapes worth knowing in advance.
He misused the machine. Under MCL 600.2947, misuse defeats a claim only when it was not reasonably foreseeable; the question is what the manufacturer knew or should have known when it made the machine, and Michigan treats that foreseeability question as one for the judge, which makes the early record critical. Workers clearing jams and reaching past guards are not exotic surprises; they are the documented realities safety standards exist to manage, and we build the proof of that.
Someone altered it. The same structure: an alteration bars the claim only when it was unforeseeable. Guards that slow production get removed in plants everywhere, and a machine that runs happily without its guard tells its own story about foreseeability.
The worker was sophisticated. Michigan gives manufacturers a defense for products provided to sophisticated users, and defendants stretch it toward any experienced tradesperson. Experience with a machine is not knowledge of its hidden failure modes, and the doctrine has limits we litigate.
Blame the employer. Your employer cannot be sued for negligence, but Michigan lets a manufacturer ask the jury to assign the employer a share of fault anyway, as a nonparty, which reduces what the manufacturer pays. This is the defense that surprises injured workers most, and it is why the employer’s maintenance and training records matter to us from day one, whether they help or hurt. When the record supports some of the criticism, we tell you, and we build the case the evidence actually supports.
Nothing in a machinery case matters more than the machine in its post-accident condition. Repaired, modified, or scrapped, it takes physical proof of the defect with it, and plants repair quickly because production resumes. A preservation letter demanding that the machine, its guarding, its controls, and its maintenance and modification history be held needs to go out immediately, and where the machine is in the employer’s or another company’s hands, inspection often has to be arranged formally, sometimes with court help. Our engineers inspect and document before anything changes, and on modern equipment that includes the electronic record: PLC logic, fault histories, safety relay configurations, and interlock states that show how the machine actually ran.
The paper matters almost as much: manuals, purchase and lease agreements, service contracts, prior incident reports, recall and service bulletin history. Discovery into what a manufacturer knew, and when, has turned individual injuries into pattern cases before, and it starts with preserving the record.
A machinery product claim compensates for wage loss past and future, diminished earning capacity, medical and rehabilitation costs, prosthetics and home modifications, a spouse’s losses, and pain and suffering. It also, practically, funds the life rebuild that comp alone cannot: the retraining, the adapted vehicle, the future a skilled tradesperson has to redesign around an injury.
Michigan caps non-economic damages in product liability cases under MCL 600.2946a; the caps adjust annually, and for 2026 stand at $596,400 in most cases and $1,065,000 where the defect caused death or permanent loss of a vital bodily function. The caps have exceptions for the most egregious cases, including where a manufacturer had actual knowledge of the defect and a substantial likelihood of injury and willfully disregarded it, a demanding showing. Economic damages, the wages and medical costs that dominate serious machinery cases, are not subject to those caps.
Two more Michigan rules worth knowing. Non-manufacturing sellers face liability mainly for their own lack of reasonable care or breach of warranty, so the manufacturer is usually the primary target. And Michigan has no general age cutoff for machinery claims: after ten years in use, the plaintiff loses the benefit of certain presumptions and must build the prima facie case fully, but plants run on thirty-year-old equipment, and cases about it remain winnable when the engineering is done right.
Your workers’ comp claim pays now; the product case pays what comp never will. When the product case recovers, the comp carrier is reimbursed under MCL 418.827 after sharing the costs of recovery, and the remaining balance is credited against future comp benefits. That statute also contains a timing rule worth knowing: if the worker has not filed the third-party case within one year, the carrier can file it. We run every client’s numbers before settlement, so decisions are made with actual figures on the table, not estimates.
Machinery cases are engineering cases, and we resource them that way: qualified experts, immediate preservation, the standards literature, and the manufacturer’s own documents. We are selective and honest: when the machine was sound and the case is comp-only, we say so at the first meeting. When the machine failed you, we prove how, and which company was responsible for building it that way.
