Yes. If you win a Texas Lemon Law repurchase, the manufacturer does not simply hand back what you paid — it buys the vehicle back for the purchase price minus a deduction for the use you got out of it, and that deduction is worked out from the mileage on the vehicle at the time of your hearing, according to the Texas Department of Motor Vehicles. The longer your case takes and the more you drive in the meantime, the larger that number gets.

What is the mileage deduction, exactly?

Under the Texas Lemon Law, a successful refund claim entitles you to the purchase price of the vehicle — including taxes, title and license fees — minus an amount charged for the vehicle’s use, and that amount is set by a formula that factors in the mileage at the time of the hearing, as TxDMV describes it. TxDMV publishes the actual repurchase spreadsheets it uses to run that calculation, but the plain-English point is the one above: the deduction is not fixed at the moment you first reported the fault, it is fixed at the hearing, months or sometimes longer than a year later.

So does waiting to file cost me money?

Not filing itself, but the miles that accumulate while your case is pending do. A case takes time to move through TxDMV’s process — the complaint is reviewed, mediation is attempted, and if that does not resolve things, the matter goes to a hearing before an examiner, who issues a decision within 60 days of the hearing closing, per TxDMV. Every mile you put on the vehicle between the day you filed and the day that hearing happens goes into the same formula that reduces your refund. Two owners with an identical defect and an identical purchase price can end up with different repurchase amounts purely because one drove the car substantially more while the case was pending.

Am I required to keep driving a car I believe is defective?

The law does not order you to park it, and for many owners the vehicle is also their only way to get to work, so the honest answer is that this is a practical trade-off rather than a legal one. What the law does require is that you give the dealer or manufacturer a reasonable number of attempts to fix the defect — satisfied by passing the four-times test, the serious-safety-hazard test, or the 30-day test, as set out by TxDMV. Time the vehicle spends out of service at the dealership for repairs does not add to your mileage or your deduction — it simply is not being driven. If a comparable loaner is provided while it is in for repair, that time does not count toward the 30 days, per the same source.

Does this mean I should rush to file the day my defect qualifies?

It is a reasonable instinct, within the limits the law actually sets. A Lemon Law complaint must be filed within six months of whichever comes first: the expiration of the express warranty, 24 months after purchase, or 24,000 miles on the odometer, according to TxDMV. TxDMV’s own guidance is that, to be safe, the complaint should be filed as soon as the consumer realizes the dealer is having trouble repairing the vehicle, rather than waiting until the filing window is closing. Filing earlier does two things at once: it starts the clock on TxDMV’s review and mediation process sooner, and it caps how many more miles you are likely to add before a hearing happens.

What if I’ve already put a lot of miles on the car before realizing it might be a lemon?

That does not disqualify a claim — the mileage deduction is a feature of how the refund is calculated, not a bar to filing one. The conditions that make a vehicle eligible are a substantial defect covered by the manufacturer’s written warranty, reported within the warranty term, given a reasonable number of repair attempts, and still unresolved, as TxDMV states. A higher mileage figure at the hearing means a larger use deduction from the purchase price, not a lost claim. It is a reason to move promptly once you suspect a defect will not be fixed, not a reason to assume it is too late.

What can I actually do to limit the deduction?

Keep driving to what you need, get the defect reported and logged in writing as early as possible, and treat the six-month filing deadline as a ceiling rather than a target. TxDMV’s own advice is to keep a log of the problem with dates and locations, keep every repair order, and file for the fastest processing through its online complaint system as soon as you realize the dealer is having trouble repairing the vehicle. None of that stops the vehicle from needing to be driven in the meantime — but it does mean the case starts moving on day one rather than after months of uncertainty about whether the fault will ever be fixed for good.

If you are trying to work out where your own vehicle stands against the repair-attempt tests and the filing deadline, check whether you qualify.
