I have a 2021 LT2 with z51 option and front lift. I have 800 miles on the car and from day one the front lift has not work properly. The car has been at a Chev dealer for 2 weeks trying to fix the problem. The reservoir has the new blue cap and is not the issue. They have been in contact with GM. Does anyone know if the front lift has been an issue on the 2021?
