What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationVolvo Cars USA LLC and Volvo Car Canada LTD on behalf of the Volvo Car Corporation has decided to launch Service Action S10306 on certain model year 2025 EX90 vehicles. Volvo Car Investigations have identified the oil plugs for the TVDC may not be torqued properly. The corrective action is to check the torque on the TVDC oil plugs and replace the oil plugs if found to be leaking. NOTE: If no leakage is found torque the oil plug screws according to the instruction. If leakage is found the oil plug screws are not to be reused and must be replaced. We expect only a small number of vehicles will need to replace the oil plug screws. S10306 affects 1,995 vehicles in the U.S and 194 in Canada.

What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 74 complaints with NHTSA since 2015. 10 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
1. The passenger side daytime fog light occasionally fails to operate, which could be a safety concern in certain driving conditions. 2. The one-pedal drive feature automatically switches off, even though it is saved in my profile. This may present a hazard if I accelerate as if one-pedal drive is still active. 3.

Common questions
Source: NHTSA, 49 CFR 579.5Is Volvo S10306 a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the S10306 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does S10306 cover?
The manufacturer filed it against 1 model year: 2025 Volvo EX90. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
