The remedy for the CC850's parking-brake recall will not require owners to visit a workshop at all.

Koenigsegg will push a parking-brake control software update over the air to every affected vehicle at no cost, and customers who prefer not to take the update remotely can have it installed at an authorized Koenigsegg dealership instead.

According to CarScoops, the seven impacted vehicles were manufactured between September 28, 2025 and August 2, 2026, and all seven examples delivered in the United States are covered.

The defect is narrow but startling. Per the NHTSA recall report cited by MotorBiscuit, when the electronic parking brake button is pressed while the transmission is in Reverse and the engine is running, the EPB will not engage.

If the driver then exits the vehicle in that state on a non-flat surface with no footbrake applied, the car can roll without driver input. CarScoops adds that the only way to engage the brake in this condition is to hold the button down continuously.

Regulators found no non-compliance with FMVSS 135 or UN R13-H, and the condition falls outside the scope of static parking-brake tests — meaning Koenigsegg appears to have recalled the car of its own accord.

Koenigsegg was notified on October 12, 2026 of an incident in which a CC850 rolled away after a driver attempted to engage the parking brake. The engine was running, reverse gear was selected, and the driver had exited the vehicle while it was parked on a slope; no injuries were reported.

The company launched an internal investigation the same day, running real-world tests and assessing how likely the condition was during normal use.

On October 19, after reviewing the findings, Koenigsegg concluded a safety-related improvement was necessary and decided to issue a voluntary recall, confirming it had received no injury reports connected to the problem.

The rollout is already in motion. Koenigsegg began notifying dealers on October 29, 2026, and owner notification letters are scheduled to be mailed from that same date.

For a halo car built around the unusual nine-speed Lightspeed transmission — which CarScoops notes uses three shafts and seven clutches and can be driven as a manual with a clutch pedal or as an automatic — keeping the parking-brake software correct matters well beyond seven cars, since the CC850's production run is capped and the fix preserves the car's value and usability.
