Complaints for the 2017 BMW 540i are spread across several systems, with no single issue dominating the field given the relatively small number of reports. Seats and electrical draw the most mentions: owners report seat restraint module malfunctions and warning lights pointing to faults in the restraint system. On the electrical side, a few owners describe the automatic emergency braking system activating unexpectedly at highway speeds with no obstacle present, which they say caused abrupt slowdowns. Tires show up as a recurring secondary item, with owners noting sidewall bubbling and slow leaks on performance-spec tires. Isolated reports mention coolant hose deterioration leading to leaks, and air conditioning refrigerant loss attributed to a leaking AC coil, with one owner noting the issue tends to surface in the 50,000–70,000 mile range.
