2021 Mercedes-Benz GLC-Class — reported problems and evidence

What owners report: issue areas

Owner complaints are classified by the system they concern: 99 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

Other / uncategorized: 8 classifications (8.1%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

These are counts of records held by CarFaultIQ, not a failure rate. More records can simply mean more vehicles were sold or more owners reported. No vehicles-in-service figure exists in this data, so no reliability or risk score can be derived from it.

What the records are about, by source

Each source is kept separate: owner complaints, recalls, manufacturer communications and investigations are different kinds of record and are never added together. All model years.

Owner complaints (1,480 records, model years 2016–2026) are most frequently classified under: engine, electrical system and fuel system.
Safety recalls (164 records, model years 2016–2026) are most frequently classified under: electrical system, body & structure and air bags (restraint system).
Transport Canada recalls (156 records, model years 2016–2026) are most frequently classified under: electrical system, air bags (restraint system) and fuel system.
Manufacturer communications (3,108 records, model years 2016–2026) are most frequently classified under: electrical system, engine and equipment & accessories.

"Most frequently classified under" reports how the records are filed by the source. It is not a finding about causes, and a record can be filed under more than one system. Read the individual records
