Michigan can't surcharge a windshield claim. The deductible is what decides it

If you carry comprehensive coverage in Michigan, a cracked windshield is paid like any other comprehensive loss, with your deductible first. Michigan has no law waiving that deductible for glass and no law making insurers sell a $0-glass option. And to clear up a common mix-up: Michigan's famous no-fault system is about injuries, not glass, so it has nothing to do with your windshield. Glass is ordinary comprehensive coverage.

The strong Michigan rule: a glass claim can't be surcharged

Michigan law is unusually clear here. The state's merit-rating statute, MCL § 500.2111(3), requires each insurer's surcharge plan to exclude comprehensive coverage entirely, and says surcharges on other coverages can be based only on at-fault accidents or traffic convictions. A windshield claim is a comprehensive, not-at-fault loss, so it cannot generate a surcharge or points. The law names comprehensive coverage by exclusion, so this is not an inference. It is written into the rule.

The honest limit: no surcharge does not guarantee no effect at all. We did not find a Michigan law that stops an insurer from dropping a claims-free discount or declining to renew for frequent claims. So the glass claim itself cannot be surcharged, but the discount and the renewal are not guaranteed.

You get to pick the shop, and the law says so by name

Michigan is one of the few states whose anti-steering law names glass directly. MCL § 500.2110b bars an insurer from unreasonably restricting you from using the shop you choose for auto glass repair or replacement, and requires it to tell you that you are under no obligation to use a particular facility. If a claims rep pushes one glass vendor, you can decline.

What Michigan does not have

Michigan has not passed a law banning assignment of your glass benefits or requiring camera-recalibration disclosure. Its only glass-specific rule is the shop-choice disclosure above.

A worked example

A rock cracks the windshield on a 2021 RAV4 near Detroit. Replacement runs about $590, and camera recalibration adds roughly $390 if needed, so the real bill is close to $980. With a $500 deductible, filing costs you $500 today and cash costs about $980, so insurance is ahead by about $480, and Michigan's rule means the claim itself cannot be surcharged. At a $1,000 deductible, insurance pays nothing and cash is the clear choice. The main thing to confirm is whether filing would cost you a claims-free discount.

What this means for your decision

Michigan takes the surcharge off the table by statute, which makes filing safer than in most states. Compare your deductible to the real price of the glass, check on your discount, and decide.
