Connecticut Lemon Law Statute of Limitations

Connecticut’s timing rules are distinctive for the 4-year action filing window under § 42-181(d) — substantially longer than peer states’ 2-year windows.

The four deadlines

Statute	Deadline	Triggered by
Lemon Law Rights Period	2 years OR 24,000 miles OR end of warranty	Original delivery date
Lemon Law action filing window	4 years from delivery	Original delivery date
CUTPA	3 years from occurrence	Date violation occurred
Magnuson-Moss / UCC	4 years from delivery	Original delivery date

2-year / 24,000-mile Rights Period

This is the eligibility window — the defect must arise AND repair attempts must occur within this window. After this window closes, the Lemon Law is no longer available for new claims.

4-year action filing window — distinctive

§ 42-181(d) provides consumers up to 4 years from original delivery to file a Lemon Law action — even if the Rights Period (2 years / 24K) has closed. This is one of Connecticut’s most consumer-favorable provisions:

• Peer 2-year states: typically 2-year action filing window
• Connecticut: 4-year action filing window

This double-window structure means a consumer whose vehicle developed a defect at month 18 (during the Rights Period) can still file at month 36 (after the Rights Period closed but within the 4-year action window).

CUTPA — 3 years from occurrence

CUTPA actions must be brought within 3 years of the occurrence of the violation under § 42-110g(f). Often longer in practice for ongoing violations or where discovery rule applies.

Magnuson-Moss — 4 years from delivery

Magnuson-Moss borrows Connecticut’s UCC § 2-725 SOL of 4 years from delivery. Matches the Lemon Law action filing window.

Practical strategy

Time since delivery	Best avenues
0 – 18 months	All open; pursue Lemon Law via DCP arbitration or court action.
18 – 24 months	Lemon Law Rights Period closing — file action ASAP while attempts/OOS still count.
2 – 3 years	Rights Period closed; 4-year Lemon Law action window still open for vehicles whose defects arose during Rights Period.
3 – 4 years	Lemon Law action window closing. CUTPA + Magnuson-Moss still available.
4+ years	Lemon Law closed; CUTPA may still be available (depending on occurrence date).

Equitable tolling considerations

Connecticut courts apply tolling in limited cases:

• Manufacturer concealment — Lemon Law SOL may toll where manufacturer concealed the defect.
• Discovery rule — CUTPA accrues at discovery of the violation, not necessarily at the deceptive act.
• Ongoing violations — CUTPA SOL accrues separately for each occurrence.

Bottom line

Connecticut’s 4-year Lemon Law action filing window is among the most consumer-favorable in the country. Stay within the 2-year / 24K Rights Period for eligibility, but you have up to 4 years total to file action. CUTPA adds a separate 3-year SOL — useful when Lemon Law has expired.
