Recall 10V601 affects 97 2011 Kenworth T800 and T660 trucks for door labels that overstate load capacity. Repair is free at any franchised Kenworth dealer.
Kenworth is recalling 97 2011 T800 and T660 trucks because the door labels overstate the actual load capacity for installed components. The inaccurate steer axle and gross vehicle weight ratings can lead an owner to overload the truck, which increases the risk of tire failure and a crash; the Kenworth dealer repair will be free once available.

What's wrong?
The certification label on a 2011 Kenworth T800 or T660 is the door label that lists the truck's weight ratings. Those ratings include the steer axle gross axle weight rating, the maximum weight the front axle assembly is rated to carry, and the gross vehicle weight rating, the maximum loaded weight for the truck. Drivers, fleet managers, and service shops use that label when deciding how much load the truck can carry.
On the recalled trucks, the steer axle rating and the overall vehicle weight rating printed on the door label overstate the load capacity of components installed on the truck. The label makes the truck appear rated for more weight than its hardware supports. If the truck is loaded according to the wrong label, the steer axle or other load-bearing parts can be overloaded.
There is no warning sign before failure. The problem is the printed certification information, not a part that changes sound, feel, or warning-light behavior before the truck is loaded beyond its true rating.
Who's affected?
Covers both T800 and T660 trucks from the 2011 model year, tied to the vehicle label placard or certification information.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Incorrect door labels can lead an owner to overload the vehicle. Overloading adds stress to the tires, increasing the risk of tire failure and a crash. Use the correct load information from Kenworth or the dealer before carrying heavy loads, and schedule the label inspection. Repair will be free at any franchised Kenworth dealer once available.
What should I do?
- Check your VIN to confirm your 2011 Kenworth T800 or T660 is included in this recall.
- Call Kenworth at 425-828-5440 to confirm repair availability before scheduling service.
- Contact a franchised Kenworth dealer to inspect and replace the door labels that overstate axle and vehicle load capacity.
- Bring the recall notice if Kenworth mailed one. If not, reference recall number 10V601 when you call.
- Avoid hauling at the listed maximum loads until Kenworth verifies the door label, because the label overstates the truck's load capacity.
What happens at the repair
At the dealer, a Kenworth technician inspects the door certification labels on the affected T660 and T800 trucks. The issue is the weight information printed on those labels, including the steer axle and gross vehicle ratings. If the label information is wrong, the technician replaces the labels with corrected versions. The dealer repair will be free once available, with parts and labor covered under the recall.
