Spending $165,000 on an SUV comes with certain expectations — and “the wheels staying attached” ranks pretty high on that list. Unfortunately for owners of the Mercedes-Benz G580 with EQ Technology, that expectation is now the subject of a federal safety recall affecting more than 3,700 vehicles across the United States.
The issue isn’t a software glitch or a battery warning. It’s something far more mechanical, and frankly more alarming: the wheel bolts connecting the wheels to the hubs can gradually loosen while the vehicle is in motion, raising the very real risk of a crash.
Why a $165K EV shipped with the wrong wheel bolts
Here’s the core problem. When Mercedes engineers built the electric G580, they carried over the same wheel bolts used on the standard combustion-powered G-Class. On paper, those bolts met the required specifications. In practice, the G580 is a fundamentally different machine — heavier, torquier, and more demanding on every fastener in its chassis.
Electric vehicles are almost always heavier than their gasoline counterparts, and the G580 is no exception. That added mass, combined with the instant torque delivery of electric motors and the stress of repeated wheel changes over a vehicle’s lifetime, creates a wear pattern that the original bolts simply weren’t designed to handle. The connection between the wheel and hub can loosen progressively, with the most dangerous scenario occurring after extreme driving maneuvers paired with multiple wheel removal cycles.
Mercedes caught the issue during its own durability testing
To the company’s credit, this recall didn’t originate from a crash report or a consumer complaint. Mercedes says it discovered the loosening problem during ongoing durability testing of the electric G-Class — when a wheel bolt came loose despite passing all required spec checks. That prompted a wider investigation, and the conclusion was sobering enough to trigger a full recall.
A total of 3,734 units are affected, covering vehicles manufactured between February 26, 2024, and August 19, 2026. Starting May 22, 2026, Mercedes will begin notifying owners directly. The fix involves replacing the original bolts with a newly engineered two-piece collared lug bolt design, which maintains more consistent friction at the contact surface and better resists wear during repeated tightening cycles. Vehicles built from August 26, 2026, onward already have the revised bolts installed from the factory.

The recall lands at the worst possible time for the G580’s image
The real story here isn’t just a bolt swap — it’s the context surrounding it. A Mercedes-Benz executive publicly described the G580 as a “complete flop” in mid-2026, which is about as brutal an internal assessment as you’ll ever hear from a luxury automaker. Sales were bad enough that Mercedes began offering $10,000 discounts on a vehicle that still carries a $164,550 price tag, hoping aggressive pricing could move units that buyers simply weren’t buying at full sticker.
Now, with a safety recall added to that narrative, the G580’s recovery path gets considerably steeper. Luxury EV buyers at this price point have no shortage of alternatives — from the Rivian R1S to the Cadillac Escalade IQ — and a wheel-loss risk won’t help conversion rates. The combustion G-Class, by contrast, had its best-ever sales year in 2026. That gap between the two versions of the same icon says everything about where consumer confidence currently sits.
What G580 owners should do right now
If you own a G580 built before August 26, 2026, the immediate step is straightforward: wait for Mercedes’ notification letter arriving from May 22 onward, then schedule your dealer visit as soon as possible. The replacement bolts are a no-cost repair covered under the recall. I’d strongly recommend not delaying this one — loosened wheel hardware is not a “monitor and see” situation.
It’s also worth asking your dealer to confirm whether your specific VIN falls within the affected build window, rather than assuming the letter covers your vehicle. Dealers will have full access to the recall database, and a quick VIN check takes minutes. Given that this issue is most likely to surface under aggressive driving combined with repeated wheel changes — something off-road-capable G-Class owners are statistically more likely to do — the urgency here is real.
The broader takeaway for any EV buyer at any price point: electrification changes the engineering calculus in ways that aren’t always obvious at launch. Weight increases, torque delivery profiles, and even something as unglamorous as a wheel bolt specification all need to be revalidated for every new platform. Mercedes learned that lesson through durability testing rather than a highway incident — and that’s the one genuinely positive note in an otherwise rough chapter for the G580.
If you own a G580 or know someone who does, share this article now and make sure they check their recall status at NHTSA.gov using their VIN before their next drive.
