GM is Recalling Nearly 3.5 Million Trucks and SUVs Over Braking Issue

Certain Escalades, Silverados, Suburbans, Sierras, and Yukons made between 2014 and 2018 are susceptible to a vacuum pump issue that can make braking more difficult and increase the risk of a crash.

The vehicles are fitted with an engine-oil-cooled vacuum assist pump. The oil fed to the pump through a filter screen that can become clogged over time reducing its effectiveness.

That can make braking harder and if that happens unexpectedly, the results could be dire.

General Motors has said that dealers will reprogram the electronic brake control module that will improve how the system the brake booster when vacuum assist is reduced.

NHTSA says it has reports of nine crashes and two injuries related to this issue. It opened an investigation in 2018.

Vehicles manufactured after 2018 were not fitted with the affected vacuum pump design and should not be subject to the same issue.
