We have a 2023 GMC Sierra 2500HD with 31000 miles that we purchased brand new off lot in 2023. My husband was pulling his boat 3 weeks ago when the truck went into limp mode. Our truck has now been at local dealership needing a transmission valve body. The valve body is on back order and we have no idea when we will receive. A transmission has been ordered as well but it also has no projected arrival date. In the meantime we are without a truck. GM refuses to provide enough rental allowance for a truck to haul what we need to haul. Does anyone know if there is a class action lawsuit for this model and if so how do we apply? This is infruating and GM does not seem to care. All they want to do is keep rolling out these think of chunks and charging an outrageous price for them.
