Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
For the 2021 BMW 530i, electrical system complaints make up the largest share of what owners report, followed by a smaller cluster of engine-related issues. On the electrical side, owners describe problems with the remote start system failing to respond and key fobs becoming unresponsive even after battery replacement. A separate electrical concern involves an apparent fire risk that prompted at least some owners to avoid parking the vehicle in enclosed structures, though that situation appears in only a few reports. On the engine side, multiple owners report collapsed motor mounts, with at least one owner noting the condition was confirmed by a dealer. A pair of complaints also touch on the backup camera or rear detection system not functioning as expected. The motor mount reports are worth noting given how that failure can affect drivability, with owners describing vibration and instability tied to the condition.

Crash-Related
By System
The 2021 BMW 530i has 7 recalls, the most serious being two separate fire risks: a corroding engine starter relay that can overheat and short circuit, and a 12-volt battery connection where increased electrical resistance can also lead to a fire.
On the drivetrain side, this recall only affects xDrive models: the output shafts that transfer power to the rear wheels can break, causing sudden loss of drive power or, if the vehicle is parked without the parking brake engaged, an unexpected rollaway. There is also a seatbelt concern where the retractor can fail to function properly in a crash, reducing the belt's ability to restrain an occupant. Two recalls cover rear visibility: in one, a software issue can cause the rearview camera image to be missing or significantly reduced while backing up, and in another, a small portion of the rearview image may be slightly obscured. Both affect drivers who rely on the camera alone when reversing.
