GM remembers over 3.4M pickup, SUVs to fix brake problems – History



– Under pressure from the federal government, General Motors recalls more than 3.4 million large pickups and SUVs in the United States to fix a braking problem.

The recall covers the Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 pickups from the 2014 to 2018 model years. The 2015 to 2017 Cadillac Escalade is also included, and the GMC Yukon and Chevy Suburban and Tahoe from 2015 through 2018.

GM says that as it ages, the pump in the auxiliary brakes can release less vacuum power than necessary, increasing the stopping distance and the risk of a break.

The recall comes after the National Highway Traffic Safety Administration began investigating the issue in November last year.

Dealers will calibrate the electronic brake control module at no cost to customers. Owners should be notified from 6 September.

NHTSA, the government's road safety agency, began investigating the problem last year after receiving 1

11 complaints from owners with poor braking ability. At that time, the agency had nine reports of crashes that had caused two injuries.

GM states that the problems occur rarely and largely at low speeds such as driving in parking lots. Even with the problem, the brakes continue to operate and exceed the requirements of the relevant federal motor vehicle safety standard, "said GM spokesman Dan Flores.

The vacuum pump is lubricated with engine oil flowing through a filter screen. In some of the trucks, oil sludge or other debris may clog the screen. Flores said the trucks have a secondary braking assist system that works when there are problems with the main system, but it is limited to lower speeds. The reprogramming will activate the secondary

GM does not replace the pumps because pump failures are rare and already covered by an extended warranty, Flores said. "This remedy will improve brake performance in any situation where brake vacuum drops," he said.

months after NHTSA opened the investigation, asking why it took so long to worship the appeal, Flores said only that the company has cooperated with NHTSA and provided data.

Drivers could feel a vibration in the brake pedal or a pressure change required to push the brake pedal if their trucks have the vacuum pump problem. If the problem arises, the owners will see a message on the dashboard asking them to operate the brake assist system, Flores said.

Although the recall is large, the cost will not be high enough for GM to report it to the Securities and Exchange Commission as an event that will have a significant impact on earnings, Flores said. He said he did not know the cost.
