Koenigsegg has filed a voluntary safety recall with NHTSA covering every Koenigsegg CC850 delivered to the United States — just seven cars from the 2025 and 2026 model years, built between September 28, 2025 and August 2, 2026.

The recall, filed October 21, 2026, concerns the electronic parking brake, which may fail to remain engaged when the engine is running and the Engage Shifter System gearbox is in Reverse.

The issue surfaced on October 12, 2026, when Koenigsegg received a report that a CC850 rolled away as the driver stepped out with the parking brake applied, reverse engaged, and no footbrake applied. The car was parked on a slope.

Thankfully, no injuries have been reported. With only 70 CC850s ever to be built and a price tag exceeding $3 million, the recall covers roughly 10 percent of the entire production run — the whole American fleet.

The recall is laughably tiny by industry standards, but for the CC850 it is literally everything: all seven US cars are on the list, and Koenigsegg figures every one of them has the bug.

According to NHTSA recall documents cited by AOL, the fault means the electronic parking brake will only stay engaged in Reverse if the driver continuously holds the button down.

If the driver leaves the car in Reverse with the engine running and no footbrake applied, the vehicle can roll on a non-flat surface without driver input, increasing the risk of unintended vehicle movement.

In a machine with Jesko's 5.0-litre twin-turbo V8 producing 1,185 hp on regular fuel and up to 1,385 hp on E85, a runaway is not a trivial hazard. The Supercar Blog notes the circumstances raise an obvious question: was the system at fault, or was there some element of user error?

The timeline in the recall documents is unusually fast.

Koenigsegg learned of the rollaway on October 12, opened an investigation the same day, and conducted real-world testing and a failure-rate assessment through October 19, when it decided a safety improvement was needed and filed the recall with NHTSA.

Notably, the NHTSA documents state the glitch is not about compliance with federal motor vehicle safety standards, because Koenigsegg's electronic parking brake system operates outside the scope of traditional static parking brake tests.

Owners are being told to keep relying on the parking brake indicator — which illuminates red when engaged and switches off when not — to confirm the brake is actually activated.

Autoblog reports the biggest danger is a driver who leaves the car in Reverse, skips the footbrake, and trusts the parking brake on a hill, letting a multi-million-dollar hypercar take a solo trip downhill.

But this recall shows the flip side of low-volume, software-defined hypercars: when something goes wrong, the affected fleet can be counted on one hand, and even a small software issue becomes big news, as The Supercar Blog puts it.

The good news is that the fault is a software gremlin, not a busted part, and no crashes or injuries have been linked to it so far.

The remedy is remarkably simple for a hypercar this exotic.

Koenigsegg will update the parking brake control software on all seven affected cars through a free over-the-air update, and Autoblog reports the update was supposed to go live over the air last week, with owner letters hitting mailboxes on October 29.

If the OTA update does not work, owners can take their car to an authorized Koenigsegg dealer for the same software fix — or, as Autoblog jokes, just to show it off. Koenigsegg has also said it will reimburse owners who already paid to have the condition remedied before the recall was filed.

Until the patch is confirmed installed, the advice is straightforward: keep a foot on the brake, mind the indicator, and never assume the electronic parking brake is holding on a slope.
