Passenger side seatbelt latch gets stuck so when trying to buckle it doesn’t go in, you have to try multiple times. Get a notification on dashboard every once in a while saying seatbelt or airbag issue contact dealer. Warning light (air bag and seatbelt system) lights up. My safety is put at risk as I am pregnant and not sure whether the seatbelt will buckle or not while I’m in the passenger seat. I have not taken this In to be looked at yet.

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 2021 Buick Enclave verdict →
