Tesla Common Problem Causes & Solutions Analysis

1.Front cover not level from left to right
Adjust the upper bracket screw on the uneven side, loosen the screw slightly then control the frunk to close, the bracket will automatically fine-tune to perfectly close the front cover, then tighten the screw.
If the method does not work:
Check whether the lock is placed horizontally. If not, loosen the two screws on the lock, make the lock horizontal, then tighten the screws

2.Mobile App can not open the frunk
1.The motor plug is not tightly inserted, or it is forgotten to be inserted. Solution: Insert the motor plug tightly.Frunk lock problem:
2.If the frunk can not be open, check the locks to decide whether it is a problem caused by gear one or gear two locks.

First, try using the mobile app frunk button several times to see if the frunk can be opened. If yes, click (not long
press) the small black dot on the control box and hear two beeps.lf not, pry the lock.(Working Theory: When
closing the frunk, the motor steel wire will draw closer to the ball stud. After closing, it will make a ” z-” sound. Loosen the wire, if there is no ” z-” sound, it means the lock is jammed. At this point, you need to pull the emergency lock wire, so the steel wire connected to the bali stud will be loosened, then the lock can be opened normally)
2) The problem is on one lock if the frunk completely does not react when pushing the button.
Check whether the original car motor plug is plugged in. If yes and the frunk still cannot work, the problem is on the original car motor. Contact Tesla Customer Service.
