The National Highway Traffic Safety Administration (NHTSA) is looking into an alleged wide spread defect in about 2.7 million trucks and SUVs from General Motors.
The Chevy Silverado, Suburban and Tahoe are all affected along with the GMC Sierra, GMC Yukon and Cadillac Escalade. The probe was triggered after 111 complaints were registered about brakes that were not working right.

NHTSA says it already knows of nine crashes ad two injuries related to the issue in these GM trucks. The power brake vacuum pump in these models can degrade over time and eventually make it difficult to stop according to NHTSA.
A recall has not been issued yet, but both GM and NHTSA are monitoring the situation closely and will decide if a recall is warranted in this situation. A Chevy spokesperson told Automotive News that GM is fully cooperating in the investigation.
