2015 Bmw M4 Safety Report

The 2015 BMW M4 exhibits a mixed safety profile based on NHTSA data. While the vehicle has a relatively low number of total complaints (11), it has been subject to 3 recalls addressing significant safety concerns. Notably, there is one reported fire incident, though no crashes, injuries, or deaths are directly attributed in the complaint data. The NHTSA has not provided overall crash test ratings for this specific model year, making it difficult to assess its performance in controlled crash scenarios. Common complaint patterns revolve around the POWER TRAIN and ENGINE components, which account for 3 and 2 complaints respectively. Specific issues mentioned in complaints include 'crank hub spinning out' leading to engine damage and loss of power, and transmission temperature warnings causing the car to go into 'limp mode.' These issues, if occurring at speed, could pose a significant safety risk. Electrical system issues, such as instrument cluster display failure and door lock malfunctions, are also noted. Recall history highlights critical vulnerabilities. One recall addresses potential rupture of side/window airbags, which could cause metal fragments to enter the vehicle. Another recall pertains to loose rear sub-frame bolts, which could adversely affect vehicle handling and control, increasing crash risk. A third recall targets a potential driveshaft slip-joint failure, leading to a complete loss of power to the rear axle and increasing the risk of a crash. These recalls indicate that BMW has identified and attempted to mitigate serious design or manufacturing defects that could compromise safety. In summary, while the complaint volume is low, the nature of the complaints and the recalls point to several high-severity issues, particularly concerning power train integrity and structural components. The lack of NHTSA crash test ratings means a key aspect of safety performance remains unquantified.

Our recommendation: Given the significant recalls and reported high-severity power train issues, thoroughly verify all recall repairs have been completed and consider a pre-purchase inspection by a BMW specialist focusing on engine and transmission health before buying a 2015 BMW M4.
