Toyota Highlander Lemon Law

Many Highlander owners report trouble with the UA80 8-speed automatic transmission: a high-pitched whine around 25 to 45 mph, delayed acceleration, hard or missed shifts, clunks, and in some cases premature failure. Toyota has issued technical service bulletins and, for certain earlier model years, a warranty enhancement program, but there is no nationwide recall that fixes the underlying behavior — leaving many owners cycling through repeated repair attempts.

Highlander drivers also report a lagging, unresponsive infotainment system, Apple CarPlay that drops or won't connect, and warning-light problems — Toyota recalled certain 2023–2024 Highlanders because an instrument-panel software error could fail to display the speedometer and the brake, tire-pressure, and other warning lights. Owners have also reported air-bag and second-row seat concerns. Any defect that substantially impairs use, value, or safety can support a claim.

Under California's Lemon Law, you don't need a recall — you need a covered defect that a manufacturer can't fix in a reasonable number of attempts, or a vehicle that's been out of service too long. If your Highlander has been back to the dealer again and again for the same transmission, electronics, or safety issue, you may be entitled to a buyback, a replacement, or a cash settlement, with Toyota paying your attorney fees.

A recall is not automatically a lemon — it's the manufacturer acknowledging a defect and offering a free repair. California's Lemon Law (the Song-Beverly Act) comes into play when a substantial defect can't be fixed after a reasonable number of attempts, or when your Highlander has been out of service for 30 or more cumulative days.

If your Toyota Highlander qualifies, you may be entitled to a buyback (a refund of what you've paid, minus a mileage offset), a replacement vehicle, or a cash-and-keep settlement — and Toyota pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
