NHTSA Complaint #11522066 — 2019 CHEVROLET SILVERADO 3500

The electrical connector vibrated loose at the injector. The mechanic said he has seen this happen before and GM said its because those motors vibrate excessively. It caused my vehicle to run in reduced power mode. In that mode it was lurching forward uncontrollably and it felt like the transmission was banging. What damage will that alone cause in the future? Also, if GM knows there is an issue, why isn't it fixed? Why is the consumer responsible for poor engineering or design flaws? It isn't normal wear and tear or neglect on my part. The repairs including the part and the rental car cost me $640.45! Oddly enough it wasn't covered under any extended warranty or recall so I had to pay out of pocket. Very dangerous and expensive!
