I have a 2016 mazda CX-9 touring, I purchase suv in April 2022, 2weeks later I started to have trouble , after turning the vehicle off it goes dead over night. I've taken it to the Mazda dealer, the battery has been replaced the cables have been tighten also the lifegate module has been replaced twice with 2 months also he said it was the sensor and then it came its a shortage in the motor of lifegate! After replacing the liftgate on left and right side, the Mazda service guy came in the next morning and the liftgate was up, and the suv was completely dead! At this point seems like everyone is a loss and I'm stuck without a vehicle I just purchased 7 months and they had had it 4 months now can't rectify the issue. Do you have any recommendations on how to solve the issue, something is drawing the battery down and the parts for these supposedly issues is very costly. Thank you so much in advance if you have any solutions please!!
