The most common problem with the BMW 4 Series gran coupe tailgate are usually related to the motor that lifts it. The power assisted motor can have problems with it and that can lead to You needing to open it manually. When the motor is having a problem the first thing that You should inspect are the fuses to it to make sure that they are in tact. If they are good then it is likely a problem with the actual motor itself. The tailgate also uses struts to help it open and if any of these get damaged then it will have a hard time opening. They can also wear out as the vehicle gets older and will need to be replaced.
