Consumer Description

My vehicle is currently in repair due to a known issue with GM. GM has put out a Technical Service Bulletin 20-NA-038 referencing a "well-known" problem with Cylinder 5 failing in 2021 5.3L and 6.0L engines. However, there has not been a recall. Ironically, there were other vehicles brought to the dealership (Sam Boswell GMC in Enterprise, AL) for the same repair on the same day as my vehicle. I'm hoping to get an initiative started for a recall
