Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

To enhance the satisfaction of our customers, avoid further costs of litigation and return focus to its core businesses, Mercedes-Benz USA, LLC (MBUSA) has entered into a settlement regarding claims relating to alleged mold and mildew type odors originating from the HVAC system in certain Mercedes-Benz vehicles. As part of the settlement, MBUSA has agreed to offer sliding-scale warranty coverage for certain vehicles diagnosed as having mold or mildew type odors originating from the HVAC system?although that coverage will not take effect until the settlement is judicially approved and other events occur; likely not until December 7, 2020 at the earliest (see below).

They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
