You press the pedal, and nothing happens. After hundreds of complaints, more than 20 crashes, and a few cars ending up inside retail stores, federal safety regulators are launching a top-level investigation into General Motors.
Modern cars are basically computers on wheels. They steer, they park, and they brake using electronic signals instead of physical cables. But when that electronic signal drops, you are suddenly sitting in a two-ton metal box that will not stop.
The National Highway Traffic Safety Administration is taking a hard look at General Motors. The agency just upgraded its probe to an “engineering analysis.” That is the highest level of investigation they do, and it is usually the last step before forcing a massive recall.
More than a million vehicles could be involved. The problem covers popular electric vehicles like the Cadillac Lyriq, Chevy Blazer EV, and the Honda Prologue. It even affects regular gas-powered trucks like the Chevy Colorado and GMC Canyon.
The issue sits inside a system GM calls “eBoost.” It ditches the old mechanical link between your foot and the brakes, using wires and computers instead. At first, GM told investigators the issue was just a broken metal spindle inside the system. But the feds kept getting reports that did not match that story. Drivers were losing all braking power right in the middle of slowing down.

The reports filed by actual drivers are terrifying.
One person driving a 2025 Lyriq lost their brakes while trying to park in front of a shop. The car jumped the curb and smashed right through the glass doors. The driver told investigators the car came to rest “midway in the store, amidst the furniture and store structure.”
Another driver in a 2024 Blazer EV realized the brakes were gone as they approached a busy intersection. They told regulators they had to “deliberately steer the vehicle into a concrete curb” to force the car to stop and avoid a “catastrophic intersection collision.”
So far, these brake failures have caused more than 20 crashes or fires and left at least six people hurt. GM is doing internal testing, but the government is no longer just taking their word for it.
When the computer telling your car to stop stops working, you do not have time to wait for a software update. You just hit the curb and hope for the best.
