Service bulletins for the 2016 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.

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

Bulletins, newest first
TechTalk76792020-10-01. Service bulletin. ENGINE AND ENGINE COOLING. Tech Talk discussion on repair verification for codes like 'low air flow' when a trailer is not available.
TS10330142020-07-31. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP; ENGINE AND ENGINE COOLING. Training Solutions for Fuel Leak Found at High Pressure Fuel Pump Weep Hole for Heavy Duty DD Engines. Occasionally we see trucks come in with fuel leaking from the high pressure fuel pump weep hole. This is NOT a defect in the pump and further diagnostics need to be performed to find the root cause.
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.
SB54-3272020-04-17. Service bulletin. BACK OVER PREVENTION; ELECTRICAL SYSTEM. Service Bulletin for Lengthening the Backup Light Harness. Though the backup light harness is long enough to connect to the backup light switch, it may be short enough that the wire seals in the connector can be stressed. Moisture entering through the seals can cause corrosion, resulting in a bad connection and/or failure of the switch. As a result, backup lights and, if equipped, the backup alarm, may not function when the vehicle is shifted into reverse.
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.
20CSA-042020-03-22. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT. Customer Service Announcement saying that Service Pack (SP) 3 for DiagnosticLink® 8.11 Standard and Professional will be available for download from the Detroit Diesel server.
