Answer:
Safety
Step-by-step explanation:
Lemon Laws were made to protect customers from defective vehicles with safety problems, or malfunction defects that affect its safety, use or value. Depending on the number of issues detected, the car reveals itself to be a "lemon". Generally, most states provide 3 attempts to solve the problem within a given period. In this case, 30 days.
Since the problem found was on the drivetrain and the axles, then it is a matter of safety after all.
