5/5 Overall
NHTSA 5-Star Safety Rating
For the 2015 BMW 328i, electrical system complaints make up the largest share of what owners report, followed by engine and powertrain issues. On the electrical side, owners frequently describe warning messages appearing on the instrument panel cluster, including alerts instructing them to shut off the engine, along with intermittent tire pressure monitoring system warnings that reset on their own without driver input. Engine complaints often involve coolant-related concerns, with some owners describing fluid escaping from the engine compartment. A smaller but notable group of powertrain reports centers on the parking brake cable bracket, which owners describe as a plastic component prone to breaking repeatedly, to the point that aftermarket alternatives have become common. The tire pressure monitoring complaints follow a recurring pattern where the warning illuminates and clears without any confirmed system fault, even after dealer inspection.

By System
The 2015 BMW 328i has 4 recalls, the most serious involving two separate airbag inflator defects: one where a side airbag inflator can rupture and send metal fragments into the cabin, and one where the driver's frontal airbag inflator can explode and strike the driver or other occupants.
A separate electrical recall covers a wiring connector that can short and start a fire. On the visibility side, the side marker lights may fail to illuminate, making the car harder to see at night.
