You can try reseating the touchpad. However, check also the battery - it may be a sign of a swollen battery, so please check this first.
If your laptop is still under warranty, I recommend you to ask for repair/replacement.
Shut down and unplug your laptop from its power source. Gently press down on any raised corners of the touchpad until they become flush with its surface, flipping your laptop while holding down this corner to make it flush with its surface and finding screws that secure its attachment to its body.
Tighten these screws carefully but without over-tightening as to not cause further damage to anything in your laptop's touchpad assembly. Once completed, flip back over and power on to make sure everything still functions as expected.
