2023 BMW 4 Series Coupe Safety and Reliability

No BMW 4 Series Coupe crashworthiness review has yet been conducted by the NHTSA, and the IIHS has also haven't crash-tested this German luxury vehicle. However, its closely related sibling, the BMW 3 Series, has attained some good reviews. The sedan managed to score a Top Safety Pick from the IIHS in 2022, meaning the 4 Series should also be very safe.

Each and every 4 Series Coupe comes fitted with eight airbags, including knee airbags for both front occupants and curtain airbags. Other industry-standard features include a rearview camera, ABS, a tire-pressure monitoring system, and stability and traction control.

As far as driver-assistance systems go, the 4 Series comes standard with automatic high beams, rain-sensing wipers, frontal-collision warning, active blind-spot detection, lane-departure warning, speed-limit info, and front and rear parking sensors. Adaptive cruise control with city-collision mitigation is standard. Available as part of the Driving Assistance Professional package for 430i models are steering and lane-keep assist, an evasion assistant, and extended traffic-jam assistance with automatic steering up to 40 mph. Besides this package, M440i models also have access to the Parking Assistance package, but the optional head-up display can only be had in conjunction with the Premium package.

There have been no recalls for the 2023 model year, but the 2022 4 Series Coupe was recalled once for a sunroof malfunction and the 2021 model was recalled for a passenger seatbelt malfunction, a rearview camera malfunction, and a head-thorax airbag deployment issue, so the car's reliability record hasn't been flawless. The 2022 model had a stellar rating from J.D. Power at 87 out of 100 for quality and reliability, but this has dropped somewhat to 84 for 2023, which is still a very good result.

BMW backs the 2022 4 Series with a four-year/50,000-mile basic warranty, a 12-year corrosion warranty, a four-year/50,000-mile drivetrain warranty, a three-year/36,000-mile maintenance plan, and four years of unlimited-mileage roadside assistance for US customers.
