WOODCLIFF LAKE, N.J. – A class-action lawsuit has recently been filed against BMW of North America alleging defective “M Compound” brakes cause excessive brake squeal and are also dangerous.

The lawsuit includes former and current owners and lessees of BMW vehicles fitted with the M Compound brakes.

The plaintiff claims he brought his 2020 M8 Convertible to the dealership 10 times due to the loud brakes and was told each time the noise was normal with “high-performance brakes.”

He was also informed about BMW service information bulletin 34 10 19:

“Inform the customer during a consultation that the M Compound (standard equipment) and M Carbon Ceramic (optional) brakes are high-performance brake systems which are designed for sporty, dynamic driving styles. As a side effect of the highest possible brake performance, customers are likely to hear noises due to the extremely resilient materials. In the same conversation, inform the customer that his/her braking performance can help ensure that the noises do not occur or disappear quickly.”

BMW Squeaky Brakes Are Allegedly Dangerous

The lawsuit goes beyond noise complaints, alleging the noisy brakes expose the driver, occupants and others on the road to an “increased risk of accident, injury, or death.”

The reasoning from the action is the squealing brakes allegedly are the means BMW drivers use to determine if their brakes are in need of repair. And if the squeak is “common,” they will not know when to go in for service.

The BMW squeaky brakes lawsuit was filed in the U.S. District Court for the Central District of California: Alber Karamanoukian, v. BMW of North America, Inc., et al.
