Well we did figure out what was wrong with it and its exactly as newdude said, only that our later on would do it in any gear, we have still not gotten the truck fixed as everytime i took it to the dealership they wouldnt look at it until it did the rear lock up while i drove taking there tech for a drive.. for one which we thought was ridiculous that they wanted us to put ourself and there employee at risk by trying to get it to do it for them to see. First time to dealership they turned me away completely and said we never heard of such a thing before.. so we continued to drive it given we are financially strapped and unable to afford another vehicle or to fix it out of pocket. We had warrenty on it the entire time aswel. Then while i was up north for work my gf had the truck do it to her and she called the dealership where we live but not where truck was from and they told her they werent able to look at it for 2 weeks. I then contacted general motors and they called the dealership and told them to take the truck imediatly for warrwnty repairs.. she went to the dealer and sat there for 1 hr 45 min as they told her they were busy and gonna have to wait.. and that they did not have a lender vehicle.. after waiting for nearly 2 hrs she had to leave to get kids from school. We then reported it to transport safety canada and then they told us to file and report our file number to general motors and we did.. then we had salesman from dealership truck come from try and buy the truck back but was also trying to put us in exact same truck but a 2023 and same trim and interior package but nearly double the price as our 2022. During the time talking to saleman during the week in hopes for a replacement the transmission completely crapped out and quick driving completely. Dealership up north had us tow it to our house with warrenty tow then to find out we had to pay for tow to the local dealership which they had told us they werent gonna charge us our monthly payments on the lease during the time its broken and then said they didnt have a lender yet again. Shortly after while truck was still in our driveway we got contacted by general motos finance department telling us we were a month behind on payments and we told them no we were told we dont have to until truck issue is resolved. He said no ans took us to collections.. truck had now sat in our driveway couple months and finaly we contacted general motos ceo and said we dont even want the truck you can have it but for the danger you guys allowed us and left us in and for the frustrations and damage to my gfs and kids anxiety and fear of tye truck having to drive it like that for over 5 months we wanted all our lease payments back since we first reported the problem and they bluntly ignored us and put us on the back burner. They refused.. then a balif showed up.. she hears story and refused to repo it and told us what to do so we then had 2 mechanics look over the truck and give us written reports both saying its unsafe.. but then the balif called us and told us she has no choice she has to repo it her boss is not giving her a choice.. so we then trailered it and have it hidden and they still refuse to compensate us at all.. and they havent found it and now are telling us they are going to take this to court which we are hoping for so we can pleade our case to the court and for them to ignore this safet issue the way we see it they voided there contract by not holding to tye warrenty policy. As of right now trucks still hidden and still awaiting to be served court papers
