NHTSA complaint #11326113, filed 2020-05, 51,600 miles“In this truck, and in other CMVs with down-facing exhaust, and with complete aerodynamic panels, exhaust gases are trapped under the body, and are circulated into the cab. Much worse when parked, but noticeable when driving. I can smell regen soot in the cab when moving at highway speed, meaning that exhaust is getting from the exhaust pipe to the cab interior. This vehicle VIN has this problem, but i have found it to be present in most other newer models of CMV, to varying degrees. The style of exhaust that ends above the roofline (vertical stacks) do not present this problem. …”
NHTSA complaint #11509676, filed 2023-03“Semi was traveling on the highway and transporting a 48,000 pound steel coil. The steel coil was secured with 4 chains. The automatic emergency braking system engaged with nothing in front of the vehicle, causing it to suddenly come to a dead stop in traffic. This caused the steel coil to break free of its bounds, crash through the trailer and into the vehicle cab, trapping the driver.”
