Replacement Vehicle Under Iowa Lemon Law

How a replacement vehicle works under IA Lemon Law § 322G.4 — comparable new vehicle, consumer choice between refund and replacement.

Under Iowa Code § 322G.4, the consumer may receive a replacement vehicle (a comparable new motor vehicle) instead of a refund. § 322G.4 generally gives the consumer the choice between refund and replacement — unlike SC § 56-28-40 or OK § 901(C) which give the manufacturer the choice.

What counts as a “comparable” replacement

  • Same model line.
  • Equivalent trim level.
  • Equivalent options package.
  • Same or newer model year — if same model year is no longer in production, next available production year is typically substituted at no charge.

When to choose replacement over refund

  • The consumer is otherwise satisfied with the model.
  • Market price has risen — refund at original price wouldn’t buy a comparable vehicle.
  • Sales-tax avoidance is meaningful — replacement typically doesn’t trigger new sales tax.
  • Financing simplicity — existing financing typically transfers.

When to choose refund over replacement

  • Consumer no longer trusts the model or manufacturer.
  • Consumer wants different vehicle type.
  • Market depreciation favors cash recovery.

The replacement process

  1. Agreement on comparable specifications.
  2. Locating the replacement — inventory search or scheduled production (2-12 weeks).
  3. Title transfer.
  4. Vehicle exchange at original dealer or designated location.
  5. Documentation update.

Reasonable allowance for use on replacement

The IA statute’s miles-capped-at-threshold-reaching-date offset under § 322G.4(1)(a)(2) is framed in terms of the refund formula. Replacement may involve negotiated use-credit terms following the same cap principle.

Options or upgrades

If the same model is no longer available:

  • Upgrade: manufacturer may offer next-trim-up at no charge.
  • Newer model year: typically substituted at no charge.
  • Different model line: more complex.

Replacement and existing financing

For financed vehicles:

  • Existing loan typically transfers to the replacement.
  • Refinancing not required.

For leased vehicles:

  • Lease transfer with VIN substitution.

Tax treatment

Replacement vehicles in IA typically:

  • No new sales tax — no new purchase transaction.
  • No new title fee — title-substitution fee only.

When replacement is not practical

  • Model discontinuation.
  • Significant price difference.
  • Consumer trust loss.

Bottom line

Replacement under § 322G.4 is the consumer’s choice (distinct from SC/OK manufacturer-option states). For consumers content with the model who just want a non-defective unit, replacement is typically acceptable. For consumers wanting cash or different brand, refund (with the consumer-favorable miles-capped offset) is the choice.
