Power windows have been around since the 1940s and are now standard on pretty much every new car, Slate Truck excepted. But this week GM was forced to recall nearly 30,000 Cadillacs because they’re replicating some dangerous habits of those early convenience features.

Though the first power windows used hydraulic power, by the 1950s automakers has switched to the electric lifts we now take for granted. But there’s one big difference between modern and classic power windows.

GM Says Supplier At Fault

In the NHTSA recall notes GM places the blame squarely on supplier Kwangjin America, who its says set the upper travel range of the anti-pinch software incorrectly. The good news for squeamish readers is that the automaker has no reports of fingers being mangled due to the goof, at least not yet.

Quick Fix, No Wrenches Required

And the remedy is a simple one that doesn’t involve tearing the door down to replace hardware. A simple software update to the Optiq’s Body Control Module on 29,347 cars at a GM dealership should ensure your kids’ mini sausages are safe for years to come. And owners who have signed up for OTA (over-the-air updates) don’t even need to visit a service center.

This week’s recall isn’t the only example of Cadillac caring for Optiq owners’ fingers. GM’s poshest brand is rolling out new infotainment software for the Optiq, Lyriq, Vistiq and CT5-V that gives the screens bigger virtual buttons. The move is a response to customer feedback reporting that the existing touch targets were too easy for fingers to miss, especially on the move.
