2012 KENWORTH T660 Complaints and Recall Information
The 2012 KENWORTH T660 has 0 complaints and 11 recalls filed with NHTSA. Owners most frequently report issues related to brakes, electrical systems, and visibility components as reflected in recall data.
The recalls affect various systems including service brakes, fuel system components, hood latches, electrical software, air supply valves, exterior lighting, air brake reservoirs, electronic stability control, and windshield wiper motors.
Recalls- Slack adjuster housing. Recall 11V157000 affects 280 vehicles. Certain cast iron slack adjuster housings may fracture due to a casting defect, causing loss of wheel brake function which can increase stopping distances and cause vehicle pull during braking. Dealers will inspect and replace housings free of charge.
- Oil module filter cap. Recall 11V127000 involves 4664 trucks. The centrifugal spinner filter cap may loosen, allowing engine oil to discharge onto hot exhaust parts, creating fire risk. Dealers will re-torque the cap and install a secondary retention device at no cost.
- Hood safety latch. Recall 11V334000 covers 72 trucks. A defective hood strut safety latch may fail to engage, allowing the hood to unexpectedly close and risk personal injury. Dealers will inspect and replace struts as needed free of charge.
- Engine software. Recall 11V380000 impacts 211 vehicles. Fast idle control can activate with transmission in gear, possibly causing unintended acceleration and parking brake override. Software updates will be provided at no charge.
- Brake air supply check valve. Recall 12V026000 affects 15,932 vehicles. Bendix relay valves may leak internally in cold conditions, causing continuous brake application, overheating, fire risk, and potential loss of vehicle control. Temporary repairs will be performed until a permanent fix is developed.
- Hazard warning lights and DRLs. Recall 15V458000 covers 12,551 trucks. Daytime running lamps override hazard lamps after brake pedal is pressed for over two seconds, reducing hazard light effectiveness and crash warning. Dealers will update cab controller software free of charge.
- Brake air reservoirs. Recall 24V145000 impacts 996 vehicles. Air tanks have insufficient volume for brake systems, lowering braking performance and increasing crash risk. Dealers will replace tanks free of charge.
- Electronic stability control software. Recall 20V199000 includes 460,515 vehicles. Loss of power to ABS controller may not trigger dash warning light, preventing driver alert to ABS failure and increasing crash risk. Dealers will update NAMUX software at no cost.
- ABS warning light. Same recall 20V199000 also covers the ABS warning light not illuminating upon ABS power loss, masking a brake system failure risk. NAMUX software updates will be performed free of charge.
- Windshield wiper motor. Recall 15V271000 affects 104,807 trucks. Water leakage into the wiper motor may stop intermittent wiper function and cause corrosion leading to electrical shorts or fire. Remedy development is ongoing and interim information has been provided to owners.
Owners of the 2012 KENWORTH T660 who face repeated repairs, unresolved safety defects, or issues related to these recalls may want to explore their rights under their state’s lemon law for possible remedies.

SERVICE BRAKES, AIR:SUPPLY:RESERVOIR/TANK
PACCAR Incorporated (PACCAR) is recalling certain 2009-2021 Kenworth C500, 2012-2021 Kenworth T440, 2009-2015 Kenworth T660, 2015-2024 Kenworth T680, 2008-2024 Kenworth T800, 2009-2020 Kenworth T370, 2013-2023 Kenworth T880, 2011-2016 Kenworth T470, 2023 Kenworth T480, 2021-2023 Kenworth T800B, and 2009-2019 Kenworth W900 vehicles. The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
Risk: Insufficient air volume can reduce braking performance and increase the risk of a crash.

SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT
PACCAR Incorporated (PACCAR) is recalling certain 2008-2019 Peterbilt 330, 335, 337, 340, 348, 365, 367, 384, 386, 387, 388, 389, 567, 579 and 587 vehicles and 2008-2020 Kenworth T170, T270, T370, T660, T680, T800, T880, and W900 vehicles equipped with NAMUX Software. In the event that the Anti-lock Brake System (ABS) loses battery and/or ignition power to the controller, the dash warning light for the ABS may not illuminate to warn the driver of the loss of ABS. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems," and 136, "Electronic Stability Control System on Heavy Vehicles."
Risk: If the driver unknowingly operates the vehicle without the ABS functioning, there would be an increased risk of a crash.

VISIBILITY:WINDSHIELD WIPER/WASHER:MOTOR
PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T270, T370, T440, T470, C500, C540, C550, T660, T800, W900, and 963 trucks manufactured November 1, 2010, to April 6, 2015. In the affected trucks, water may leak into the wiper motor.
Risk: As water leaks in, the wiper may cease to function on the 'intermittent' setting, reducing the driver's visibility and increasing the risk of a crash. Additionally, the water may cause corrosion which, over time, may result in an electrical short, increasing the risk of a fire.

EXTERIOR LIGHTING:HEADLIGHTS
PACCAR Incorporated (PACCAR) is recalling certain model year 2011-2016 Kenworth T440, T470, T660, T680, and T880 trucks manufactured January 14, 2010, to May 22, 2015, and equipped with HID Headlamps and the option for Daytime Running Lamps (DRL). The DRLs are required to deactivate when the hazard warning lights are activated, however, the DRLs on these vehicles override the hazard flashing functionality after the brake pedal is pushed for more than two seconds. Normal hazard flashing functionality returns once the service brake is released. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."
Risk: If the hazard warning lamps are overridden by the DRL, oncoming vehicles may fail to be warned, increasing the risk of a crash.

SERVICE BRAKES, AIR:SUPPLY:CHECK VALVE
PACCAR IS RECALLING CERTAIN MODEL YEAR 2012-2013 KENWORTH T170, T270, T370, T440, T470, T660, T700, T800, W900, AND PETERBILT 320, 330, 337, 348, 365, 367, 382, 384, 386, 388, 389, AND 587 VEHICLES, MANUFACTURED FROM JANUARY 31, 2011, THROUGH JANUARY 19, 2012, AND EQUIPPED WITH BENDIX ATR-6 ANTILOCK TRACTION RELAY VALVES. IN EXTREMELY COLD CONDITIONS, THESE BENDIX RELAY VALVES MAY POTENTIALLY DEVELOP INTERNAL LEAKAGE. INTERNAL LEAKAGE CAN LEAD TO AIR PRESSURE BEING DELIVERED TO AFFECTED PRIMARY OR SECONDARY BRAKE CAUSING CONTINUOUS BRAKE APPLICATION.
Risk: UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE BRAKES TO OVERHEAT AND LEAD TO A FIRE. UNEXPECTED CONTINUOUS BRAKE APPLICATION CAN CAUSE THE DRIVER TO LOSE CONTROL OF THE VEHICLE, INCREASING THE RISK OF A CRASH. ALSO, THE BRAKES MAY BE APPLIED WITHOUT ILLUMINATING THE BRAKE LIGHTS, FAILING TO GIVE PROPER WARNING TO OTHER DRIVERS.

SERVICE BRAKES, AIR:SLACK ADJUSTERS
PACCAR IS RECALLING CERTAIN MODEL YEAR 2011-2012 KENWORTH T270/370, T440/T470, T800, T660, W900 AND C500 VEHICLES MANUFACTURED BETWEEN OCTOBER 18, 2010, AND JANUARY 28, 2011. CERTAIN CAST IRON SLACK ADJUSTER HOUSINGS, WHICH TRANSMIT BRAKING FORCE FROM THE BRAKE CHAMBER PUSH ROD TO THE BRAKE CAM TUBE, MAY INCLUDE A FLOW NOTCH IN THE HANDLE PORTION OF THE HOUSING DUE TO AN ERROR DURING THE CASTING PROCESS. A FLOW NOTCH IN THE HANDLE PORTION MAY REDUCE THE EFFECTIVE CROSS SECTION STRUCTURE AND CAUSE THE SLACK ADJUSTER HOUSING TO FRACTURE.
Risk: IF THE SLACK ADJUSTER HOUSING WERE TO FRACTURE, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER HOUSING IS ATTACHED WOULD NO LONGER FUNCTION, WHICH COULD INCREASE VEHICLE STOPPING DISTANCES, AND IF MOUNTED ON THE STEER AXLE, COULD CAUSE THE VEHICLE TO PULL TO ONE SIDE DURING BRAKING, INCREASING THE RISK OF A CRASH.
