Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2018 BMW M4 sits amid a declining trend in federal complaints and recalls that began at a peak in 2015 and 2016, when complaints jumped to 12 and 21 respectively. 2018’s five complaints and single recall represent the lowest levels seen since 2014, and the year‑to‑year TSB count fell to 134 from 188 in 2017. The primary complaint areas in 2018 were Fuel/Propulsion System (four complaints) and Engine (one complaint), with no crash or fire complaints reported. This marks a clear improvement in the generation’s safety and reliability trajectory, suggesting that a 2018 model is less likely to encounter major issues than earlier or later years. Overall, 2018 is a solid choice for a used M4 buyer looking for a vehicle with fewer reported problems.
