Oil in the power distribution box can kill drive power, ABS, lights, wipers and the defogger on twelve 2027 models. Owner letters are not due until September 25.

PACCAR Recalls 5,919 New Kenworth and Peterbilt Trucks

Almost six thousand brand-new trucks are carrying a defect that can shut off the lights, the wipers and the drive power at the same time — and the letters telling owners about it are not scheduled to go out until late September. That gap is the part worth planning around.

What the filing actually says

The campaign is numbered 26V485000 and was filed on July 27, 2026. It covers 5,919 units and reaches far more than one flagship model. Twelve 2027 model-year configurations are on the list: Kenworth W990, T880, T680, T480, T380 and T280, plus Peterbilt 589, 579, 567, 548, 537 and 536. If it is a 2027 PACCAR product, it is worth checking rather than assuming.

The defect sits in the power distribution center, the box that feeds the truck's electrical circuits. It may be contaminated with oil. When that happens the filing lists five possible consequences: loss of drive power, loss of Antilock Brake System function, loss of exterior lighting, loss of windshield wipers, and loss of the defogging system.

That combination is why the paperwork cites three separate federal safety standards — the ones covering defrosting and defogging, windshield wiping and washing, and lamps and reflective devices. A truck in that condition is not merely inconvenient. It is out of compliance with equipment rules an inspector checks directly.

The remedy exists, the parts timeline does not

Dealers will inspect the serial numbers on the box and replace it where needed, at no cost to the owner. The important detail is scheduling: interim letters notifying owners are expected to be mailed September 25, 2026, and a second round of letters will follow once the final remedy is available. In plain terms, the fix is defined but the parts flow is not yet.

This is also not a park-it recall. Federal regulators did not tell owners to stop driving or to park outside, and there is no over-the-air update that resolves it. The truck keeps working until the failure shows up, which is exactly what makes it easy to postpone.

Why the wait is the operator's problem

An inspector at a scale house does not weigh why your marker lights are dark. A lighting or wiper failure is written up on what it is, not on what caused it, and a pending campaign number does not change the equipment standard the truck has to meet that day. The same logic applies to ABS: the warning lamp is a check item, and an ABS fault on a tractor is a familiar line on an inspection report.

There is a second cost that does not show up on a repair order. A truck that loses drive power in traffic, or wipers in weather, turns into a recovery call, a missed appointment and a service event you did not schedule. Owner-operators absorb that directly.

What to do before the letter arrives

  • Check the VIN yourself, do not wait for mail. The federal recall lookup takes a VIN and returns open campaigns; the letter is a courtesy, not the trigger.
  • Call the dealer with the campaign number in hand. Peterbilt customer service is 1-940-591-4220 and Kenworth is 1-425-828-5888. PACCAR's internal number for this one is 26PACD.
  • Stop treating intermittent electrical faults as gremlins. A wiper that hesitates, a marker light that flickers, an ABS lamp that clears on its own — on a 2027 unit those now have a documented suspect.
  • Photograph and date what you find. If a failure happens before the remedy is available, a dated record of the symptom and the service call is what supports the claim later.
  • Put it in the pre-trip out loud. Lights, wipers, defogger and the ABS lamp are already on the walkaround. For these units they deserve a second look, not a glance.

The recall itself is good news in one sense: the defect was found, the responsible part was identified and the repair is free. The risk is the eight weeks in between, when nothing has arrived in the mail and the truck feels normal.

One last note on scope: campaign 26V485000 covers specific units, not every 2027 truck these two brands built. Confirm by VIN before assuming your unit is either affected or clear.
