Mercedes-Benz GLS Lemon Law

The GLS's most alarming defect is a fire risk. Mercedes recalled certain 2021–2023 Maybach GLS 600 vehicles because a 48-volt ground connection under the passenger seat may not have been secured properly during assembly. A loose ground lug can increase electrical resistance at the connection, causing it to overheat — which raises the risk of a fire. Dealers were directed to inspect and tighten the connection, and owner notification letters went out in May 2024 under Mercedes' recall 2024040002.

The GLS was also recalled for a fuel-pump defect: the fuel pump may shut down, resulting in a loss of drive power. Losing power while driving is a serious safety hazard that can increase the risk of a crash. Owner notification for that campaign was mailed in June 2024 under Mercedes' recall 2023070012.

The GLS is a heavy, complex luxury SUV, and owners also report electrical faults, air-suspension issues, and driver-assist glitches on top of these recalls. A recall by itself does not make a vehicle a lemon — but when the fix doesn't hold, the same defect keeps recurring, or your GLS sits out of service waiting on parts or repairs, California's Lemon Law may entitle you to a buyback, replacement, or cash settlement.

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 GLS has been out of service for 30 or more cumulative days.

If your Mercedes-Benz GLS 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 Mercedes-Benz pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
