BMW M4 — reported problems

What owners report: issue areas

Owner complaints are classified by the system they concern: 126 classifications in all. One complaint can concern several systems, so these add up to more than the number of complaints.

• Engine32 (25.4%)
• Powertrain (transmission & drivetrain)28 (22.2%)Official recall records for this system: 2, covering model years 2015–2017.
• Fuel system16 (12.7%)Official recall records for this system: 1, covering model years 2020.
• Suspension12 (9.5%)
• Electrical system10 (7.9%)Official recall records for this system: 1, covering model years 2026.
• Brakes6 (4.8%)Official recall records for this system: 1, covering model years 2021.

Other / uncategorized: 6 classifications (4.8%) 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 (92 records, model years 2015–2024) are most frequently classified under: engine, powertrain (transmission & drivetrain) and fuel system.
• Manufacturer communications (1,398 records, model years 2015–2026) are most frequently classified under: equipment & accessories, electrical system and body & structure.

"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

Mileage reported when the issue occurred

• 42reports included a mileage
• 32,338average of those mileages

This is the mileage owners recorded at the time they reported, not an expected failure mileage and not a prediction for any individual vehicle. The lowest and highest figures on record are not shown: they are unverified odometer entries that include zeros and implausibly high readings, so they would not describe a real range. A median is not shown either, because the stored figures are group totals and a median cannot be recovered from them.

Counts are not adjusted for how many vehicles were sold in each year, so a taller year is not necessarily a worse year.
