Lamborghini service campaign L636- A.18.25
Lamborghini filed this with NHTSA as a service campaign dated Nov 3, 2025, received Dec 3, 2025, about the power train. It names 1 model year (2025). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationDue to the installation of a non-appropriate fixing clip on the rear sport differential harness, it is possible that it gets loose and comes into contact with the driveshaft. In case of the mentioned cable gets damaged, the signal for the sport differential may be cut and instead of having an electronic guided sport differential with specific functions, the system goes into recovery, with specific pop-up to alert the driver, but the traditional mechanical differential continues to work normally. Therefore there is no influence in the handling or acceleration/braking, only the more sport-like setting is affected. This is considered as a quality issue only. The action is for the replacement of the fixing clip with a reinforced one.
