On XXX while driving my 2018 GMC Terrain SLE 1.5L turbo on the highway at approximately 70 MPH near [XXX]. I experienced a sudden loss of power brake assist without any prior dashboard warning lights or messages.

Dear [Manufacturer], I am writing to report a serious safety concern with my [year, make, model]. A bolt from the idler arm/undercarriage came off after becoming severely rusted. I had the vehicle inspected by a repair shop, but they could not determine why the bolt failed or why it had rusted to this extent. This is extremely concerning because a failure of this component while driving could potentially result in loss of control and a serious accident. I am asking the manufacturer to investigate this issue and determine whether this is a known defect or corrosion-related problem. Please let me know if you would like to inspect the vehicle or failed component. I look forward to your resp
