When I lock my car the alarm sounds very weak,
thought it was because I was running low on gas,
but I filled up my tank and it's still having the same
issue. What could be wrong with it? The car is only
a couple of months old.
Your car is still under factory warranty. Take it to the dealership and they will get it sorted out for you.
It is likely that the horn is weak or bad. A defective horn has no relationship with how much fuel is in the tank.
