Peterbilt and Kenworth truck throttle pedals can stick
PACCAR is recalling certain 2023-2024 Peterbilt 535, 536, 537, 548, Kenworth T280, T380, T480 and 2024 T180 trucks because an oversized magnet carrier can slow the throttle pedal or make it stick.
What this means for you
Our assessment, not the agency’s: severity 4/5 (Severe).
The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: Rubric level 4 covers structural vehicle defects: a physically oversized part in the throttle assembly can cause the pedal to stick, taking speed control away from the driver of a heavy truck.
