I have a 2019 Grand Sport 2LT. Just turned 5500 km and last week I discovered two bent rims, both on the LHS. I haven't hit anything as far as I know and there's no visible damage to the tire or rim but so far GM says no warranty. Anyone heard of a class action lawsuit against them in Canada? There are a couple of lawsuits underway in the US but apparently they can't or wont include cars owned by Canadian residents. Thanks
