It is difficult to brake at low speeds; I have to press very hard for it to brake. I took my 2017 Chevrolet Silverado in to a shop in reference to a safety recall, they said they followed the procedures for that recall, but I have the same issue. I believe the proposed solution is not fixing the problem. This has been on going for at least three years. To be clear, this happens when there is REPETITIVE braking at low speeds. Typically after three times braking at low speeds (0-5 mph). What component or system failed or malfunctioned, and is it available for inspection upon request" Brake How was your safety or the safety of others put at risk? It is difficult to brake anytime there is repetitive braking at low speeds, including but not limited to parking lots, drive thru, or heavy traffic. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, per the safety recall message. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes.

I have notice from OnStar for issues with Antilock braking and on the vehicle dash notice for brake assist problems. I have experienced pedal pressure changes at very slow speed where I had to push very hard to stop the vehicle. Search and info from Consumer Reports indicates this is a problem for this model year, however I have not been notified of a recall and none is listed on this web site. I have scheduled service, but I believe this vehicle should be added to the recall.
