Consumer Description

My daughter was driving her 2019 GMC Terrain at 15 - 20mph when she suddenly lost her brakes. Fortunately she had just turned into a new housing development where the road ended into an empty field. This could have been catastrophic for her & other citizens on the road. The following morning she would have been heading to work on a highway with heavy traffic with a posted speed limit of 65mph. We towed the vehicle home & after some investigating I found a vacuum pump failure. This vacuum pump broke apart internally sending chunks & shards of metal into her valve train. This issue is mentioned several times in Terrain forums & someone needs to address this issue before it becomes a fatality.
