Lemon laws only apply to safety issues.
Lemon laws vary by state, but most are quite broad. Texas for instance covers new vehicles, including cars, trucks, vans, motorcycles, all-terrain vehicles, motor homes, towable recreational vehicles (TRVs), and neighborhood electric vehicles that develop a defect(s) covered by a
manufacturer’s written warranty (this is key). Demonstrator vehicles that have not been previously titled are considered new vehicles. The law does not cover repossessed vehicles, non-travel trailers, boats, or farm equipment.
Nor does it cover defects that do not substantially impair the use or market value of the vehicle such as minor rattles, radio static, etc.
There are, in Texas, 3 tests to see if it is covered:
Four-times test
If you have taken the vehicle to a dealership for repairs four times for the same defect within the first 24 months or 24,000 miles, whichever comes first, and the defect is still not repaired.
Serious safety-hazard test
A serious safety hazard is a life-threatening malfunction that substantially impedes your ability to control or operate the vehicle normally or that creates a substantial risk of fire/explosion. You pass the serious safety-hazard test if you have taken the vehicle for repair of a serious safety hazard during the first 24 months or 24,000 miles, whichever comes first, and the defect is still not repaired.
30-day test
If you have had your vehicle out of service for a total of 30 days or more - not necessarily all at one time - during the first 24 months or 24,000 miles (if a comparable loaner vehicle was provided while the vehicle was being repaired, that time does not count toward the 30 days) a substantial defect still exists, and this test is passed.
