NHTSA Complaint #11521632 — 2018 GMC TERRAIN

In mid traffic my 2018 GMC terrain just stopped with no warning, no check engine lights, no smoke from the vehicle, nothing. I was in Charlotte traffic, driving, with my family in the vehicle, the car stopped right in the middle of driving, and I had to quickly and sharply turn the wheel to got into a median to avoid hitting the car in front of me and avoid being rear-ended. The dealership informed me that the vacuum pump in the engine cracked (broke) causing another part in the engine to malfunction. There were no, none, warning lamps, messages, or other symptoms prior to this incident that would of indicated a problem so that I can proactively service the vehicle and keep my family safe.
