Have taken it to the GMC dealership over seven times with same issue. They refuse to fix problem due to not being able to replicate it. Losing steering and braking issue is getting worse. This is a LARGE HEAVY TRUCK and GM refuses to help fix. This is very disturbing. Has to be something in the drive train.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 GMC Savana Cargo G33705 verdict →
