Overview

2018 BMW M4

The 2018 BMW M4 is a potent performance coupe that delivers thrilling driving dynamics. Under the hood, it boasts a 3.0-liter, 6-cylinder engine paired with a rear-wheel-drive system. While its EPA estimated combined fuel economy is 19 MPG, owners should be aware of the significant number of Technical Service Bulletins (TSBs) recorded, which indicate a history of minor to moderate issues requiring dealer attention. One recall campaign addressed front seat belts. Buyers should prioritize a thorough inspection of any outstanding TSBs and confirm the recall has been completed.

Critical Failure Risk

The M4's high-performance engine generates significant heat, placing stress on the cooling system. Leaks can develop from hoses, the radiator, or the water pump, leading to overheating.

Early detection can help you avoid a $3,000-$7,000 repair.
