Service bulletins for the 2021 Freightliner Coronado

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

30 on file from NHTSA, as of 2026-10-19.

Bulletins, newest first
SB31-0432020-07-31. Service bulletin. EQUIPMENT; SUSPENSION:REAR. Freightliner Service Bulletin for Non-Airliner Rear Suspension Crossmember Fastener Change. With the start of production on March 2, 2020, the fasteners used to assemble the non-Airliner rear suspension (bogie) crossmember have changed. The rear suspension bogie crossmember gussets to the C-channel will be assembled with 5/8 - 18 fasteners. This change includes a revision to a higher friction nut that requires an increase in tightening torque. The new higher friction nut can be identified by its green color.
SB60-1712020-07-28. Service bulletin. STRUCTURE:BODY:DOOR. Service Bulletin for Guidelines for Cleaning and Disinfecting Cab Surfaces. The following guidelines are for cleaning and disinfecting commonly touched surfaces on the inside and outside of a vehicle. For best results, follow cleaning and disinfecting procedures fully and consistently. Ensure there is adequate ventilation when using chemicals. NOTICE: Wipe down fragile components carefully to avoid damaging the vehicle.
CALFTLWS000-012020-04-09. Service bulletin. TIRES; WHEELS. Customer Advisory Letter for GWR Label Correction. Freightliner 108SD/114SD, Coronado, New Cascadia, and Business Class M2 vehicles and Western Star 4700 and 4900 vehicles equipped with a certain tire rating have the wrong Component GWR label. DTNA is requesting the current Component GWR label be replaced with the correct label.
SB32-0332020-03-31. Service bulletin. SUSPENSION. Freightliner Service Bulletin for Front Axle Spacer Replacement. This service bulletin replaces the version dated 05/01/2016. This bulletin is updated to include the parts list. Some vehicles may exhibit a lean (right or left) due to weight difference on the front suspension. While this does not affect the operation of the vehicle, it may be visually unpleasing to many customers. To correct this condition, replace the existing front axle spacer on the low side of the vehicle with a thicker one.
SB00-0382020-03-18. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; SUSPENSION. Freightliner Service Bulletin for vibration troubleshooting - finding the cause. This version replaces the version dated 5/1/14 and adds New Cascadia.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
