Wagoneer & Grand Wagoneer Lemon Law in California

The Wagoneer and Grand Wagoneer are Stellantis's full-size flagships — big, expensive, technology-dense SUVs — and that complexity has come with real defects. California's lemon law, the Song-Beverly Consumer Warranty Act, covers them like any other vehicle sold with a manufacturer's warranty. If a covered defect substantially impairs the vehicle's use, value, or safety and the manufacturer cannot repair it within a reasonable number of attempts, you may be entitled to a buyback, a replacement, or a cash settlement, with the manufacturer paying your attorney fees.

The 2026 brake-control-module recall

The most serious recent defect is a braking-system software problem. In 2026, Stellantis recalled roughly 12,000 early-production 2026 Grand Wagoneer and Grand Wagoneer L vehicles because suspect software in the brake system control module — the unit integrated with the brake booster and master cylinder — could disable electronic stability control and cause a loss of electronic brake assist. Losing stability control and brake assist on a three-ton SUV is a serious safety defect. The remedy is a software update, and if that update does not resolve the behavior, or related braking problems persist, that is exactly the kind of issue a lemon claim is built on.

Electrical, software, and drivetrain complaints

Beyond that recall, Wagoneer owners report the broader set of problems common to these big, feature-heavy Stellantis SUVs: electrical faults and dead 12-volt batteries, Uconnect infotainment and screen failures on the multi-display dashboards, stop/start and mild-hybrid eTorque quirks, and assorted software glitches that send the vehicle back to the dealer. Any substantial defect that keeps returning after a reasonable number of repair attempts — or that leaves the vehicle out of service for an extended period — can support a claim. A recall is never required.

What a buyback is worth, and the deadline myth

A buyback refunds what you paid — down payment, monthly payments, and official fees such as tax and registration — minus a single mileage offset for the use you had before the defect first sent the vehicle in. A willful failure to comply allows a civil penalty of up to two times your actual damages. On a Grand Wagoneer, which stickers well into six figures when loaded, the numbers are substantial, and the manufacturer pays your attorney fees when you win.

And the 18-month / 18,000-mile figure is a presumption period, not a deadline — missing it costs you an automatic shortcut, not your claim, and many claims are proven on the repair history alone.
