Volvo and Mack Recall the Same Roof Marker Lamp Again, Now on 2,364 2027 Trucks

Counting the marker lamps, the Volvo Group's current highway cab has now generated three FMVSS 108 campaigns since last November. Between the two marker-light recalls came 26V208000 and Mack's parallel 26V207000 in April, covering turn signals that may not function properly on 2025-2027 VNL (4), 2026-2027 VNR (4) and Mack Pioneer and Anthem units.

The remedies tell you which of these costs shop time. The turn signal defect was closed with a software update to the indicator logic. The marker lamp is hardware: dealers replace the center roof marker light, free of charge, on both the Volvo and Mack campaigns. Volvo's internal number is RVXX2608; Mack's is SC0498. Affected VINs became searchable through NHTSA's recall lookup on August 13.

Owner notification letters on both campaigns are not expected to go out until October 5 — two months after the filing. That leaves a window in which an affected truck can be running a known non-compliant lamp while its operator has no letter in hand, and a required marker lamp that does not light is citable at roadside whether or not the mail has arrived. The VIN lookup closes that gap; the letter does not.

One more filing from the same August 6 batch is worth a note on the PM sheet. International's campaign 26V516000 covers just 49 units of the 2027 HV, HX, LT, MV and RH, where a retaining nut in the wiper assembly may loosen and disconnect both windshield wipers from the motor. The remedy is a torque check — dealers tighten the wiper motor drive nut and three motor mounting bolts — which is a few minutes of labor on any service visit.

Run VINs first. Any 2027 VNL, VNR, Anthem or Pioneer taken into the fleet this year should go through the NHTSA lookup now rather than in October, and the same applies to 2026 New VN units against 25V757000.

Then stop paying for the lamp. If the roof marker on an affected VIN is already dark, the replacement is covered under RVXX2608 or SC0498, and buying one over the counter spends money the campaign already pays for. Quote the campaign number at the dealer.

For everything outside the recalls — older VNLs, Pinnacle and Granite units, mixed-age fleets — roof marker and clearance lamps stay an ordinary consumable, and the assemblies changed with the cab. Confirm which model years share the cab and lamp fitment before you pull a part number off an older invoice, and verify the interchange on that number before ordering an aftermarket equivalent. A lamp that does not seat correctly on the roof line is the same FMVSS 108 problem the recall is trying to fix, only on your dime.
