Is Your Car a Lemon? Understanding the Repair Attempt and Days-Out-of-Service Rules
Think your vehicle is a lemon? Learn how the 'reasonable number of repair attempts' and 'days-out-of-service' tests work to help you secure a refund or replacement.

Understanding the 'Reasonable' Repair Test
If you have ever spent more time in a dealership waiting room than on the open road, you know the frustration of a vehicle that just won't stay fixed. Many owners assume that if a car has a problem, it is automatically a 'lemon.' However, the law generally requires that you give the manufacturer a 'reasonable' number of opportunities to fix the defect before you can claim a refund or replacement [7].
So, what exactly is 'reasonable'? While state laws vary, most jurisdictions rely on two primary benchmarks: the number of repair attempts for a specific issue and the total number of days the vehicle has been out of service [3, 7].
The Two-Pronged Test
Most state Lemon Laws use a two-pronged approach to determine if a vehicle qualifies for protection [3].
First, there is the repair attempt threshold. This usually means you have brought the vehicle to an authorized dealer for the same recurring problem—often three or four times—without success [1, 3, 6]. It is important to note that these aren't just any visits; they must be documented attempts to fix a 'nonconformity,' which is a defect that substantially impairs the vehicle's use, value, or safety [4, 7].
Second, there is the days-out-of-service test. If your car has been sitting at the dealership for a cumulative period—often 20 to 30 days—due to warranty-covered repairs, it may qualify as a lemon, even if the specific repair attempts vary [1, 2, 3, 6]. This recognizes that a car that is constantly in the shop is just as unreliable as one that cannot be fixed at all.
Why Documentation is Your Best Friend
Because these laws rely on specific counts, your paperwork is your most powerful tool. Every time you drop off your vehicle, ensure you receive a detailed repair order that clearly describes the problem. When you pick it up, get an itemized invoice that lists the work performed and the date. If the dealer says they 'could not duplicate the problem,' keep that record too—it proves you brought the car in for a concern that remains unresolved [9].
What to do next
If you suspect your vehicle is a lemon, follow this checklist today:
- Gather your records: Collect every repair order, invoice, and receipt related to your vehicle's issues.
- Check your warranty: Confirm that the issues occurred within your state’s specific time or mileage limits [3, 9].
- Send written notice: Many states require you to send a formal letter via certified mail to the manufacturer (not just the dealer) to notify them of the defect and provide a final chance to repair it [1, 2, 6, 8].
- Keep a log: Start a simple calendar tracking every day the car is in the shop and every conversation you have with service managers.
- Seek professional guidance: If the problems persist, don't wait for the warranty to expire. Consult with a qualified attorney to see if you are eligible for a buyback or replacement.
