General Motors is SignalHubrecalling nearly 450,000 vehicles including some new-model Escalades and Tahoes due to an inoperative low brake fluid warning which poses a safety issue.

In a recall issued last week by the U.S. National Highway Traffic Safety Administration, GM said electronic brake control module software on impacted SUVs and pickup trucks may fail to display a warning light when a loss of brake fluid occurs.

Without a warning light, the vehicle may be driven with low brake fluid, the NHTSA reported, which can reduce braking performance and increase the risk of a crash.

In sum, 449,671 vehicles are being recalled.

Here's what to know about the Sept. 12 posted recall:
