"General Motors voluntarily remembers several 2014-2018 models of the year Cadillac Escalade, Chevrolet Silverado, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, and GMC Yukon vehicles for a condition related to increased brake pedal efforts, ”GM said in a statement statement. "In rare cases, these vehicles may have a condition where engine-mounted mechanical vacuum pump output may decrease over time, decreasing the amount of vacuum / assist brake power."

As pumps in power-assist brakes put less vacuum force than required, "customers may experience increased brake pedal effort, hard pedal pedals, and / or potentially increased stopping distance. "

All of these issues can increase the risk of a crash. buying more expensive trucks.

Flores says the issue is more prevalent at low speeds when the brakes are gently applied, and the brakes continue to operate and meet the requirements of the Federal Motor Vehicle Safety Standard. [19659005] As the National Highway Traffic Safety Administration (NHTSA) began investigating the issue in November, GM only contacted NHTSA for several months on the issue.

NHTSA did not respond to a request for comment by email and telephone.

GM was invited to take action based on field reports and customer complaint information.

"Traders will discuss the electronic control control module in these vehicles with a new calibration that will improve how the system uses hydraulic brake boost to assist function when vacuum assistance is lost," he said. Flores.

Traders will be able to redistribute the electronic control control module at no cost to customers.
