How Long Do I Have to File a Texas Lemon Law Claim?

Texas’s lemon-law timing rules are more complicated than most states because three different statutes carry three different deadlines. See our detailed statute of limitations article for the full framework.

The three deadlines

Statute	Deadline	Triggered by
Texas Lemon Law (TxDMV)	6 months after the earliest of: express-warranty expiration, 24 months, or 24,000 miles from delivery	Original delivery date
Texas DTPA	2 years from discovery of violation	Date of false/deceptive act or discovery
Magnuson-Moss / Tex. Bus. & Com. Code § 2.725	4 years from delivery	Original delivery date

TxDMV’s filing deadline

Under Tex. Occ. Code § 2301.606(d), a TxDMV complaint must be filed no later than six months after the earliest of: (1) the express warranty’s expiration, (2) 24 months from original delivery, or (3) 24,000 miles. The 24-month / 24,000-mile point isn’t the deadline itself — it (or an earlier warranty expiration) starts a six-month filing tail.

This deadline is jurisdictional. Once it passes, TxDMV typically lacks authority to act regardless of the facts. Everything runs from original delivery (date of first retail sale), not from when you bought the vehicle or when the defect manifested.

This is the most-missed deadline in Texas Lemon Law practice. Don’t let the manufacturer’s “we’re still working on it” delays push you past it.

DTPA’s 2-year limitations period

Tex. Bus. & Com. Code § 17.565 sets a 2-year statute of limitations for DTPA claims, running from the date of the deceptive act or discovery (whichever first). For warranty-breach DTPA claims, the discovery date is usually when the defect manifested or when the manufacturer first refused warranty.

DTPA’s 60-day pre-suit notice requirement under § 17.505 doesn’t extend the limitations period.

Magnuson-Moss / breach-of-warranty 4-year limit

Magnuson-Moss doesn’t have an explicit limitations period. Texas courts apply the most analogous state-law period — 4 years from delivery under Tex. Bus. & Com. Code § 2.725.

Practical strategy

Time since delivery	Best avenues
0 – 18 months	All three avenues open; TxDMV is fast and cheap.
18 – 24 months	The earliest trigger is approaching; line up your TxDMV complaint.
Within 6 months after the earliest trigger	Last window to file with TxDMV; DTPA and Magnuson-Moss also open.
After the 6-month tail closes	TxDMV closed; pursue DTPA and Magnuson-Moss.
2 – 4 years	DTPA likely past limits; Magnuson-Moss available.
4+ years	Few viable options.

Mileage- and warranty-based triggers for the TxDMV deadline

The 24,000-mile threshold and the express-warranty expiration date are independent of the 24-month time threshold. The six-month filing clock starts at whichever comes first. A vehicle with high mileage accumulation may reach 24,000 miles in 8-12 months, starting that clock early.

For high-mileage drivers, file at the first credible opportunity.

What “discovered or should have discovered” means

For DTPA’s 2-year period, courts look at when a reasonable consumer would have known the violation occurred. For warranty breaches:

• Repeated unsuccessful repair attempts typically trigger the clock.
• The manufacturer’s express refusal to honor warranty does too.
• Manufacturer “goodwill” offers that fall far short of statutory exposure may also start the clock.

What to do if you’re past TxDMV

If you’re past the six-month filing deadline (counted from the earliest of warranty expiration, 24 months, or 24,000 miles):

1. Don’t give up on the case — DTPA and Magnuson-Moss may still apply.
2. Document the timeline carefully.
3. Talk to a Texas lemon-law attorney about which avenue fits.
4. Send any required pre-suit notices promptly.

File promptly

If you suspect you have a Texas Lemon Law claim, get a free case review early in the timeline. The closer to the defect manifestation and the active warranty period, the cleaner the case. The longer you wait, the harder it becomes to win — even if you’re technically within a deadline.
