Certain vehicles may have two potential conditions. First; the front caliper may have been produced out of specification on the caliper clearance to the rotor. This can result in brake drag, reducing brake pad life, and the potential to pull to the right or left. Second; the rear caliper may have been damaged during vehicle assembly. This damage may have caused a microcrack in the rear brake calipers piston. This microcrack can result to a leak path for the brake fluid, eventually illuminating the BRAKE malfunction indicator lamp (MIL). Dealers are to replace both front and both rear brake calipers.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10189165-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10189165-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10189165","components":[{"id":"lighting","name":"Lighting","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"EXPRESS","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_chevrolet_express"]},{"make":"GMC","model":"SAVANA","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_gmc_savana"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
