Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Not sure if it is a malfunction or not. Can not verify. Seller mentioned: “Allison Automatic Transmission will not shift from Neutral to Drive or Reverse unless you hit the brake”. It does shift w/o braking. This seems like it would be a safety issue but Freightliner Techs can not verify. Vehicle is new to me and has not been inspected yet although I did consult Freigthliner tech via phone. No warning lights related. Operates fine otherwise.”

NHTSA complaint #11432993, filed 2021-09
